  7. 7. Glenmarie Cove, Klang fences Discarded construction wastes and soil after excavation are placed at the vacant land next to the site. Temporary toilet for the workers. hoardings Concrete mixer is located here because it is near to where the materials are unloaded. Only road access to the site. Open storage area for gravels and bricks and a lockable storage hut for security and weather protection. Sands and construction materials are unloaded at the main entrance of building since it is easier to transport the materials to other parts of the building. Electrical generator. SITE LAYOUT Workbench to cut the pipes.
  8. 8. Taman Bukit Segar, Cheras Retaining wall for the site to prevent landslide since it is located on the hill. Water tank Electricity substation Boundary line for the site where it is surrounded with hoardings and fences. Main entrance, only in and out access for the site. Guard house is located at the only access to the site. Storage area for floor tiles along the road access. Portable toilet located in the middle of the site for the convenience of the workers. SITE LAYOUT Dump site for the wastes.
  9. 9. The amount of materials to be stored in this site is a lot so there are a lot of storage area distributed along the site according to where the materials are needed the most. Site office Canteen and accommodation for workers where the toilet is next to it. Slowest progress of all construction of the houses. Location to unload materials since it has a bigger space and the buildings here are mostly still in earlier stages. Reinforced steel bars are placed here as beams and columns are still constructed in this part of the site. Location of steel bars cutter and bender. SITE LAYOUT Materials are unloaded here because it is near to where the storage area.
  10. 10. Security The loss of construction equipment from theft being one of the major source that causes a construction project to be more expensive and may also result in the delay of production whilst waiting for new equipment as well as the paperwork of said stolen equipment. As such people with control of the workplace are normally there to ensure that unauthorized personnel not be given access to the site. Signboards Construction sites are better known as one of the most dangerous environments to work in due to the high possibility of being seriously injured. With the presence of high voltage areas, falling debris and heavy equipment, it's important to make sure that construction workers and anyone in or near the site are made aware of the dangers there. SITE SAFETY With that in mind, safety signs are normally present in numerous locations on both sites to remind the contractors or other people in the vicinity of the site regarding the safety and restrictions.
  11. 11. Meeting To achieve their objective, Meetings should be structured communication sessions, with an agreed goal and outcomes. People have to be led in order to function efficiently and reach decision appropriate to the organization. advance of commencement of work on site. Meetings help the principle contractors to explain the role of safety, health and environmental management, together with any specific requirement related to the project. A copy of the completed agenda should be signed off and retained on file for record and audit purposes. SITE SAFETY A pre-start meeting are normally held by principle contractors on a specific location on site with each contractor in order to discuss the overall site safety plan through the
  12. 12. Equipment Head protection :- Function to provide protection against sun and rain, and against impact damage to the head. A regular safety helmet has a life span of 3 years but can be shortened by prolonged exposure to ultraviolet light and repeated minor or major impact damage. Footwear :- Provide protection for feet especially for the toes, if material should drop onto them. Also provide protection against penetration from beneath the sole of the foot, be reasonably waterproof, provide good grip and designed to comfort. SITE SAFETY Gloves :- Carefully selected on consideration of cause and hazards likely to be encountered by wearer in order to ensure compatibility with field of construction.
  13. 13. Equipment Mask :- Use to purify the air by drawing it through a filter to remove contaminants, breathing apparatus, which supplies clean air for wearer from uncontaminated external source. Making proper choice of mask provide efficiency when used correctly. any fall, and to assist in rescues from confined spaces. Belts are preferable compared to harnesses as for the movement needs of the work. Harnesses are to withstand the snatch load of any fall, by basically attach the securing lanyard to a fixing point as high as possible over work area. SITE SAFETY Harness :- Only use on platforms, nets or other access and personal suspension equipment is impracticable is their use permissible. Belts and harnesses are limit to the height of
  14. 14. Electricity As electrical installations on construction and demolition sites may pose serious risks to the safety of construction and demolition workers., several simple precautions are normally taken in order to reduce the risk of electrical injury to the contractors and people on site. Regular visual inspection of electrical equipment will identify most faulty items, but not all faults can be seen. Because of this, testing at appropriate intervals is required, depending upon the treating the equipment receives in use. Work near overhead and underground lines requires planning. Carrying metal ladders and scaffolding tubing near overhead wires can provoke arcing – safe clearance distance must be obtained. The best options in advert ant context can be prevented by choosing traffic roots to avoid, or building goal post or collapsible barriers beneath them on either side so that the barrier is hit before the cable. SITE SAFETY
  15. 15. Roadwork Traffic management plan is an important aspect at a construction site and should be included in every project safety plan. With main access and egress point to the site, there needs to be good visibility and room for manoeuvring wherever possible as it is important to keep pedestrian footways and vehicle path physically separated. This is most commonly done by identifying and marking entry and exit point with reels or barrier. using pedestrian footways while crossing. SITE SAFETY Banksmen should allows assist drivers in reversing, and to be trained in traffic management plan and signalling. Additionally, high-visibility clothing should be worn by everyone
  16. 16. Dumper All construction sites should have a planned maintenance program by which dumpers will operate in enclosed areas within building structures, or in confined spaces, adequate ventilation must also be ensured. Dumpers must secure vehicles when loading, tipping or parked. Drivers must wear safety helmets, and dismount during loading. Ladders and step ladders must be checked to ensure correct length, type and condition for use. It should be subjected to a planned maintenance program. Length must be extend to a sufficient height above the step-off point when used for access. Step ladder must be placed at right angles to the work and the users hips should be below the top platform to ensure stability and prevent side loading. In Site A, uses wooden self-made ladder in the beginning to mobilize to the next level after a certain period, they use aluminium ladder using the scaffolding to support the ladder. After realizing that the wooden ladder could no longer reach a certain height. For Site B, in comparison to the aluminium ladder in site A they use the wooden self-made stairs in order to reach higher platforms. SITE SAFETY Ladder
  17. 17. Fall Fall prevention is far more effective than fall protection. Reliance on people to make the “right” decision about wearing personal protective equipment as to be shown by events to be unsatisfactory –they forget, decide to not wear it in view of the expected short exposure time, of wearing it incorrectly. Methods to prevention :• Use a working a platform fitted with guard rails and toe boards where practical. • Only when the situation is not practicable, or when protection has been removed for a period, a method of arresting falls must be used. • Harnesses and lines do not prevent falls but do provide protection for those falling. An effective barrier can be provided by sheeting below the guard rails down to floor level. All holes should be protected properly, either by guard rails if they are large enough, or by securing a cover above them that is prominently not ‘Danger-hole beneath.’ SITE SAFETY
  18. 18. Self-propelled Crane Cranes are lifting devices designed to raise materials by means of rope operation and move the load horizontally within the limitations of any particular machine. (cite) Lorry mounted crane is one of the example mobile cranes which can be found on site, where it consists of a lattice boom mounted on a lorry. It has two operating positions, the front cab where driver drove and another parts where crane is being controlled. It is suitable to be used in short hire period because it took less time in site preparation process. ▲Example of excavating front bucket Highway Dumper Backhoe Loader Backhoe loader is one of the common construction plants that has been used in site B. It is used in small excavation works. It is fitted with one excavating front bucket and a rear backhoe attachment. When using the rear backhoe attachment, the machine is raised off its axles by rear mounted hydraulic outriggers. Most of them can be fitted with different size of buckets and various attachments, such as bulldozer blades, scarifiers, grab buckets and post hole auger borers. Dumpers are used for the horizontal transportation of materials on or off the construction site. Highway dumper has a better function than a typical dumper because it is larger in size. This helps the highway dumper in carrying other materials such as excavated spoil along the roads. It has a rear tipping skip which is useful in discharging the materials. SITE MACHINERY Lorry Mounted Crane This machinery is only used in site B. Compare to Site A, Site B has a larger scale in project size. Unlikely to the lorry mounted crane, self-propelled crane is a mobile cranes mounted on a wheeled chassis and have only one operator position from which the crane is controlled and the vehicle driven. A variety of self propelled crane formats are available ranging from short height lifting strut booms of fixed length to variable length lattice booms with a fly jib attachment.
  19. 19. Cement Mixers Most cement mixers in general use will have a rotating drum designed to produce a concrete without segregation of the mix. Output performances of a cement mixer is always the main consideration in designing it. Generally a batch mixing time of 5 minutes per cycle or 12 batches per hour can be assumed as a reasonable basis for assessing mixer output. (cite) This cutter is a rare machinery used in construction site. Due to the special design of Site A’s façade, which is covered by aluminium panels, the cutter is needed for so. It is used to cut an edge by the sides of the panels so that it could be bent into shape. Picture at the right shows how the workers use the machine. Rebar Cutter and Bender Rebar cutter (left) and bender (right) are important tools in handling the reinforcement bars. For example, when the bars need to be shaped, the bender plays an important role on it. In another hand, rebar cutter helps in cutting the bars into ideal length. Both of the machines need electricity supply to function. Face Shovel The function of face shovel is to excavate above its own track or wheel level. This builder plant is preferably to be used in excavating any type of soil but not hard object such as rock. Basically, it requires a haulage vehicles nearby to carry the spoil away. It has a limit where it could not reach 300mm-400mm below its wheel level. SITE MACHINERY Aluminium panel cutter
  20. 20. The electricity supply is not always available on a construction site, therefore, portable generators are needed to provide electricity for some tools application. In compare to site A, site B has a generator with higher voltage (Image in the middle) as to support the larger site electricity requirement. Care is always needed while setting up the generators under advise of expert to ensure site safeness. For example, the location of placing the generators has to be taken into consideration, such as, placing them away from drains or watercourses. Maintenance has to be frequently done to ensure the generators work more effectively. Hand Drill Nail Gun Since Site A is more towards a finishing period, it uses more hand tools compare to Site B. This is because less external works and structure parts are to be done. Drill is one of the hand tools that can be used to drill holes on a surface. As figure shown above, drill helps in making a small drainage for the connection of wire. Nail gun is one of the hand tools that is used in driving nails into the surface of some specific materials, which are mostly hard surface materials. In site A, this tool is to be applied on concrete wall. Permit is needed in using this tool due to the bullets contain gun powder inside. Picture above shows the bullet of the nail gun. Two bullets at the middle with red colour tips are those which have not been use yet. SITE MACHINERY Electric Generators
  21. 21. External Work -Marking External work starts with plotting the site and site clearing. Based on plan drawn on paper, the boundaries of the land has to be identified. The plotted land is the place where construction will be initiated. Before the construction can begin, the trees and bushes within the boundaries have to be removed so that construction can progress smoothly. Pay special attention to the roots of trees which might damage the structure in the future if they are not removed completely. Setting Out Marking the excavation site by pegging in the ground OR to mark the floor for the erection of the walls. Marking the boundaries requires a few steps. Lining out Determine the positions of the corners and the distance between them. Then mark the positions of foundations, footings and walls (including the thickness) by pegging in the ground. Direct marking For buildings that are small like the houses in site A and site B may marked directly on the flat ground. But for site B the uneven ground may have to be flatten first. Mark the location and measurement of the foundation on the ground using the plumb bob and dig the trenches. Uneven Ground During setting out in site B, the distance between 2 horizontal points is used, not the distance along the slope. The points have to be extended upwards using a plumb bob and then the distance between 2 points is measured. When setting a boundary along a slope, this method is used together with the 3-4-5 method. Right angle can be constructed as long as all the lines are straight. The length of the pegs might have to be different to keep the lines straight and off the ground. SETTING OUT 3-4-5 Method The idea of 3-4-5 method is the use the Pythagoras theorem to acquire the right angle of the boundaries. The first horizontal line that is peg on the ground is called front line. The front line is measured 4 metres in total length. Then the 2nd line, which is 3 metres, is pegged vertically from the starting point of the front line. To make sure that front line and the second line is right-angled to each other, the ending points of the front line and the second line has to be 5 metres. This is the theory of Pythagoras theorem. It should be easy to form a rectangle. If the marking is done correctly, the diagonals should be equal.
  22. 22. EXCAVATION Earthwork: the processes whereby the surface of the earth is excavated and transported to and compacted at another location. It ranges from works such as the excavation of ditches and trenches for drainage and pits and trenches for foundations. It is usually carried out at an early stage in a construction project, completion of the earthworks within the scheduled time is often the key to the completion on time of the whole project . Before excavating any land , planning , designing , construction , environmental and geological conditions are taken into consideration . The land must be cleared off well , before any type of construction can take place. The stability of the slopes were controlled by the density and strength of the materials that were used to form the slope and the groundwater conditions. Successfully controlling the surface water and maintaining the moisture range can lead to a successful earthwork operation. Soil collapses: When the excavated material is not placed far enough away from the edge of the excavation. The recommended minimum distance for location of excavated soil (spoil) from the edge of the excavation is equal to or greater than the excavation depth. Another one is when common in clay-type soils when excavation walls are too steep, or when moisture content increases rapidly. EARTHWORKS ENVIRONMENTAL: The earthworks should not disfigure but rather blend into the environment. Transportation and minimize disruption of the local environment. Consider natural and waste resources in the area , such as are produced from the pits and quarries and other machinery used on the site.
  23. 23. Septic Tank Septic tanks consist of two chambers and do not fully treat sewage. Septic tank is better waste water management compare to other system due to few reasons. Advantage Can be built and repair with locally available materials Little space require due to underground construction No energy required Outlet Tee Scum (, 2013) Name Inlet Tee Effluent Filter Outlet Tee Effluent Scum Function Decrease speed of incoming wastewater and reduce the disturbance of settled sludge Prevent solid from leaving septic tank Protect drain field from clogging Maintain scum and solid waste in tank Wastewater that sending drain field and broken down by aerobic process ,filter through soil and return to groundwater to be reused Contains of detergent, grease and other chemicals that less dense than wastewater Prevents oxygen from dissolving in the sewage and cause anaerobic process take place SERVICES Inlet Tee Disadvantage High cost compare to other systems such as dry or composting toilet system Sufficient amount of piped water is required constantly to send the waste to treatment unit Only suitable for
  24. 24. As volume of sludge and scum increase, the time and space for the solid to separate before wastewater leave the tank decreases. The septic tank has become less effective. Solids should be removed by periodic pumping to avoid clogging and prevent overflow of drain field. Each septic tank has to be pumped every 3 years to 5 years. The cleaning period depends on the size of septic tank, type of solid waste in septic tank and amount of solid waste in septic tank. There are two types of method to set up of a septic tank: 1. Gravity-fed system 2. Alternative septic system Site A and Site B share same method to set up septic tank which is gravity-fed system. SERVICES Gravity-fed system 1. Assemble equipment and machinery require for excavation such as backhoe tractor, shovel, contractors’ dummy level and rod. 2. Success permit process which include a test to determine type and size of drainage field require in the installing system in Site A and Site B. 3. Plan the flow to go downhill as gravitational force will make the flow to move faster and to discharge the waste from tank. Concrete aerobic divided tank and perforated pipe embed in gravel. 4. Excavate a whole large enough to set the septic tank below ground. The size of septic tank is calculated to be at least twice the accumulating sludge volume. The maximum amount of sludge that a septic tank can store is approximately a third of its volume (, 2013). 5. Place rock from nearby gravel pit around the pipe to hold the pipe in position. 6. Cover up the pipe and tank once
  25. 25. Sump pump Sump pump functions to collect water around the foundation and redirect it away from foundation. There are two types of sump pumps that are usually installed: 1. Submersible pumps 2. Pedestal Name Function Check Valve Allow fluid to flow in one direction Discharge Pipe Direct the discharge away from foundation Weeping Tile - Prevent overflow of water - Connect to sump pit The setting up begins after the foundation is complete. The drain pipe is installed under the gravel around the entire perimeter of the home. (, 2013) 1. Excavate sump pump pit for sump pump liner and sump pump to be placed. 2. Use jackhammer to break the floor around the edge of concrete flooring and a layer of clean stone is placed. Perimeter drain is installed at this place to collect water from the wall floor joint and direct it to the installed sump pump pit. 3. A special outlet connects the perimeter drain to sump pump and gravel is placed around sump pump liner to keep sump pump as clean as possible. Airtight sump pump lid around all pipes and wire prevent from rising out of sump pit and prevent anything to fall into foundation. 4. Connect the check valve and attach PVC discharge piping. Run the piping up the wall and out through the hole that drill in the rim joist. 7. Extend piping to outside to allow water to remove from foundation. 8. Seal around hole in rim joist with caulk. 9. Plug the sump pump into GFCI receptacle. Fill the basin with water and test pump. SERVICES (, 2013)
  26. 26. Wastepipes Process: 1. Cut a 2-inch hole through the bottom plate of the wall behind the toilet with a hole saw. Secure the toilet flange to the floor with deck screws. Be certain that the slots provided in the flange for the base of the toilet are in the correct position to insert the bolts for the base of the toilet. 2. Cut a short section of the 1½-inch pipe with the skill saw. Be certain it is long enough to fit from underneath the floor into the wall. Slip it through the 2-inch hole. The rest of the drain line will be installed from under the house. 3. Apply PVC cleaner (or primer) to the elbow and the flange followed by the glue. Install the elbow onto the flange from underneath the floor giving it a slight twist. Be certain it "seats" and is facing the correct direction. 4. Install the reducer to the short section of the reduced size vent pipe you cut in Step 2. Install the "T" on the end of the elbow so that one end of it points up for venting and the other is down. Secure the reducer to the "T" facing up. 5. Install sections of the toilet drain pipes using the method described in Step 2. Break up the different sections of pipe as needed to connect to the line leading to the sewer or septic tank. Be certain there is enough of a descent to keep the water flowing to its destination. 6. Install plumbers strap around the pipe under the house. Measure a piece long enough to reach around the pipe and secure to the floor joists. It can be secured with box nails or screws. 7. Cut a hole through the top plate of the wall for the vent pipe. Secure a pipe coupler to the end of the pipe coming up from the floor. Cut a piece of vent pipe long enough to reach above the ceiling. From there, cut and secure enough vent pipes to go through the roof. SERVICES There are many types of waste pipes in different dimension of sizes. Before installation of waste pipe, the degree of slope is an important aspect to be considered. Piping from the toilet should take several precautions: a. Piping should be 45 degree slope or more to vertical or at 2 to 3 degree to ensure the waste able to flow through. b. Piping should not slope upward c. Connections should be snug to avoid “hang up” where pipes meet connector. d. Use sealant such as silicon for the connection of waste pipes to the connecting unit to ensure the composing unit is able to move

  28. 28. Being the lowest part of a building, constructed partially or wholly below the ground surface, foundation is used to: • To support and anchor the superstructure above. • To transmit all the dead and imposed loads safely to the ground causing no or minimal settlement or other movement. Uniform settlement Differential settlement which would impair the building structure ii) Subsoil movements are due to changes in volume when the subsoil becomes wet or dry and occurs near the upper surface of the soil. Compact granular soils such as gravel suffer very little movement where as cohesive soils such as clay suffers changes in volumes. A chart on the bearing capacity based on types of soil FOUNDATION Problems faced by foundations: Subsoil: i) The subsoil beneath foundation is compressed and reacts by exerting an upward pressure to resist foundation loading. If foundation load exceeds maximum passive pressure of ground a downward movement of the foundation could occur. Solution for this is to increase the plan size of foundation to reduce the load per unit area or alternatively reduce the loadings being carried by the foundations.
  29. 29. The soil type for both sites is generally soft clay or laterite soil which is common in west coast of the peninsular of Malaysia. Low soil strength Low residual strength Characteristics of soft clay High compressibility • • • • High compressibility: higher chances of settlement to occur. Low permeability: Might retain water and make changes to the soft clay as it is very sensitive to the level of moisture content. Low residual strength: The soil strength of soft clay decreased if it is disturbed. Low soil strength: Could not withstand the heavy load from the building structure. Trees: • Direct physical contact by tree roots could do damage to the substructure of buildings. The effect of the shrinkage or heave of moisture level in the soil, especially clay subsoil will also impair the foundation system. • Trees up to 30 m distance may have an effect on foundations, therefore reference to local authority building control policy should be undertaken before specifying construction techniques. FOUNDATION Low permeability
  30. 30. Both sites used combined pilings and raft foundations. Raft foundation normally consists of a concrete slab extending over the entire loaded. It is used to spread the load of a structure over a large base to reduce the load per unit area being exerted on the ground. It is usually used when individual column loads or other structural loads are heavy. Raft foundations have the advantage of reducing differential settlements as the concrete slab resists differential movements between loading positions. They are often needed on soft or loose soils with low bearing capacity as they can spread the loads over a larger area. The edge of the raft foundation is determined by the nature of the loading applied. 1. Light load 2. Light load and point load columns 3. Heavy uniform load 4. Heavy and isolated point load Plan for raft foundation Ground beam Perspective of raft foundation The raft foundation for the Glenmarie Cove site is the fourth because the building structure is heavy and the columns are all isolated. FOUNDATION Cross section of raft foundation with beam at the bottom
  31. 31. Why raft foundation with pilings are used? • inadequate bearing capacity of shallow foundations • to prevent uplift force • to reduce excessive settlement (Consolidation - soils decrease in volume when stress is applied to a soil that causes the soil particles to pack together more tightly) Glenmarie Cove, Klang: • The poor soft clay soil condition of Port Klang • The site is very near to the river • The building is 3 storeys in height which exerts huge loads on the foundation There are two ways on how the piling system works to transfer loads to the ground: i) End Bearing Piles are driven down to a point where they bear on bedrock or dense granular soil at the foot of the pile. ii) Friction Piles can be driven into soil far enough that the friction of the soil against the sides of the pile is enough to resist any downward movement. End bearing pile Friction pile FOUNDATION Taman Bukit Segar, Cheras: • low bearing capacity of soft clay soil at the site • situated on the hill top and have slopes • Heavy loads as the buildings range from three to four storeys in height
  32. 32. There are two methods on how the piles are installed: i) Driving • Driven pre-cast pile: The pile is casted in a yard brought to the site and driven by some mechanism into the soil • Driven Cast-in-situ pile: A casing plugged at bottom is driven into the ground and then the pile is casted by removing or retaining the casing ii) Boring • Bored Pre-cast pile: A bore is made and the soil inside is removed and then a pile casted in some yard is put into the bore • Bored Cast -in-situ pile: A bore is made the soil is removed and the pile is casted at site in the bore. Both sites used driving method with hydraulic jack-in pile machine for the piling system, as the site at Taman Bukit Segar, Cheras used pre-cast concrete piles. Both sites used end bearing piles. Patented grip jacking system FOUNDATION The reasons hydraulic jack-in pile machine is used: i) Lower noise and vibration as both sites are located in the middle of the residential areas ii) Faster construction rate iii) Higher quality control iv) Lower damage to the piles Main jacking cylinder v) Cleaner construction method Concrete piles Main support frame Heavy counter weights to prevent the rig from being lifted when the piles are jacked into the ground Hydraulic jack-in pile machine Support sleepers

  34. 34. Pile Cap Starter bars to make column stump to join the foundation with the column Anchor bolt Reinforced steel cage Starter bars from the pile Concrete slab approximately 10cm thick Pile caps are linked together with reinforced concrete ground beams. The usual minimum spacing for piles is: i) Friction Piles 1100mm or not less than 3x pile diameter, whichever is the greater. ii) Bearing Piles 750 mm or not less than 2x pile diameter, whichever is the greater. For the site at Glenmarie Cove, the distance between the piles on the site is 400mm each, twice the diameter of one pile which is 200mm, as they are end bearing piles. No pile cap was used but through the drawings, extra reinforced steel bars were added into the concrete ground beam structure to increase the strength of that particular part that has piles. FOUNDATION Concrete pile
  35. 35. Elevation of the raft foundation Extra reinforced steel bars piles Section of the raft foundation Reinforced steel bars Walls/ columns Concrete slab soil hardcore 50mm lean concrete • 16mm reinforced steel bars are used in the foundation. • The thickness of the ground beam is generally 600mm as it needs to increase the surface area in contact with the soil to be more stable while the concrete slab is only 150mm in thickness. The reason why the concrete slab doesn’t need to be as thick as the ground beam because it’s not the supporting structure for the building. • Hardcore is the infill of materials such as broken bricks, stone or concrete, which are hard and do not absorb water or deteriorate. It is spread over the site within the external walls of the building to a required thickness to raise the finished surface of the foundation concrete. Hardcore bed is usually 100 to 300 mm thick. • Hardcore should be clean and free from old plaster or clay that sticks on broken bricks as those materials might decrease in volumes over a period of time. • Lean concrete is used to prevent the direct contact of the foundation concrete with the soil. FOUNDATION Steel mesh
  36. 36. Process of constructing a foundation: 1. Soil tests are being conducted before excavation is started. 5. The soil is marked and concrete piles are driven into the ground according to the ground plan using hydraulic jack pile driver. 6. Holes are dug for the pile caps and formworks are set up so that the concrete can be mold. Reinforced cage are installed. Reinforcement for column stump is installed. Pile caps are then casted with concrete on top of the piles. Pile cap is left till the concrete hardens and formworks are removed. 7. Formworks for stump are set up and stumps are formed. Trenches are dug and lean concrete is poured to form a layer on the ground. Reinforced steel bars are placed in it. Concrete is poured to form the ground beams and concrete slabs and steel mesh are placed in between the slabs. Once the foundation is done, columns and walls can be erected. FOUNDATION 3. Topsoiling (removal of a desirable soil surface) is carried out because topsoil contains organic matter which makes it unsuitable to be load bearing soil. 2. Appropriate site investigation works need to be carried out to determine depths of filled ground, bearing capacity of soils, soil type and any existing workings or services that may clash with pile locations.
  37. 37. In both Site A and Site B, they share a similar building process of ◄ Column stump is a lower structure which is built above a foundation pad constructing building frameworks, and it’s located in the ground below the waterproof layer at ground floor which is built in-situ reinforced slabs. The column stump are useful in transferring the loads of a building concrete. Before any construction of into the foundation and it acts as a supporter for ground beams and ground beams and slabs, a column stump is floor column construction. needed to be built on top of a pad foundation which extended from the piling below foundation. First of all, ground beam are first built before any structures. Ground must be cleared before ground beam is built followed by a blinding layer on top of the surface. The ash blinding plays a role in preventing the concrete from losing moisture. ▲ Set up of beam reinforcement. ▲ Example of beam formwork structure After the blinding process, the reinforcement will be tied to the column stump to hold them in position. Reinforcement steel bars is useful in providing the tensile strength which plain concrete lacks off. Formworks which are made from plywood are then set at the surrounding of the reinforcements of the ground beams together ground floor slabs. Plywood is one of the most convenience materials of formwork and it has a lower cost, hence, it is widely used in construction including both Site A and B. Lastly, concrete mixed will be poured into the formworks. The curing period will took around 2 to 3 weeks. Once the concrete are dried up, the formworks can be taken off and are reusable for up to three time at least. ▲ Example of ground beams in Site B BEAMS ▲ Process of beam construction layering
  38. 38. ▲ Reinforcing steel bars ▲ Stretched, twisted and ribbed steel bars are used in both site ▲ Starter bars are extruded out from the formwork to provide connection for the next structure. ▲ Reinforcing steel mesh As reinforcements inside the ground beams set before, they are tied with extended reinforcement bar for a better connection to the ground floor slabs. Such extended reinforcements are called starter bars. A new reinforcement mesh is then places between the ground beams and is tied to the starter bars of the ground beams. Similar process is repeated, where the concrete is poured into the reinforcements which are surrounded by the plywood formwork. Compare to any other slabs at different levels, ground floor slab will usually have damp proof property. This is very useful in withstanding the forces of the slabs and to prevent greens grow underneath them. that is different from Site A which is the houses have overhang slab at the top ceiling area which near the roof level. The slab is extruded from indoor ceiling to outdoor. It has a function of blocking rain water from ▲ Image above shows how reinforcing steel mesh are tied to beams reinforcement spreading to the house. ▲ Scaffoldings set below the first floor slab acts as a supporting system SLABS In Site B, there is one feature
  39. 39. Columns are the last framework that will be built in the on the ground floor area. Although they have the similar construction process as both beams and slabs, but column is a vertical structure whereas the other two are horizontally built. Since columns are built above the column stump, reinforcements steel bars of columns will be tied to the starter bars on column stump. This can ensure that the beams load and weight are transferred down to the foundation. Columns are usually built in storey height, therefore it is important to ensure the structural continuity of the reinforcements. Steps that have been applied on beams and slabs are repeated again at where formworks are set up continued with concrete pouring into it. Although the plywood formworks are taken off after the curing period, they are once again set of the edge of the built column. These formworks set play an important role in continuing the construction of the formworks for building first floor beams.

  40. 40. CONCRETE Concrete is a heavy, rough building material made from a mixture of broken stones or gravels, sand, cement and water spread and hardened. PROCESS PROCESS Through self-placing and self-leveling concretes (concrete that is placed without vibration). Step 1 : The site needs to be cleared. Step 3 : After the sub base is compacted and the forms are set concrete mix are placed. Concrete is poured directly from the chute of the ready mix truck, wheeled into place with a buggy, or pumped into place with a concrete boom pump. Concrete is normally specified at a 4-5 slump. Step 4 : Once wet concrete has been placed into the forms, a large metal or wood board is used to screed the top of the concrete. This screeding process helps compact and consolidate the concrete, and begins the smoothing and leveling of the top of the concrete. Once the surface has been screeded, the concrete is floated. This involves using a special trowel called a float. Floats can be a small hand held trowel for edges and detail work, or a large trowel called a bull float for working large areas of the concrete surface. Step 5 : Floating and troweling is a process of compacting and smoothing the surface which is performed as the concrete starts to harden. Step 6 : Once all the troweling (float or steel) is complete the final finish can be applied to the concrete. The most basic type of finish is known as a "broom finish". A special broom is pulled across the concrete surface creating a rough textured surface. Step 7 : Once concrete has been placed and consolidated it must be allowed to cure properly to develop good final properties. As the concrete hardens and gains strength it becomes less and less vulnerable, so the critical time period is the first hours and days after it is placed. Proper curing of concrete generally comes down to two factors, keeping it moist and keeping it supported. To cure properly, the cement paste much be fully saturated with water. FLOOR SYSTEM Step 2 : Forming. Once the sub base is prepared, forms can be set. Forms are attached to stakes with screws or special nails to allow easy removal of forms after the concrete has cured.

Granite tiles are used as the flooring in the master bedroom and the other bedrooms. Marble Tiles • Made from limestone or dolomite rock. • Colour of marble ranges from purest white to black. Travertine Tiles • Is a natural stone such as marble, granite and Slate. • Formed in hot springs or limestone caves. • Standard size is 0.5 inches thick. Marble tiles are used as the flooring in the bathroom in the main bedroom. Based on my knowledge, I do not think it is suitable to make it as the flooring in the bathroom. Because when it gets wet, someone might trip and fall down. On the contrary, it is suitable as the wall tiling. Granite Tiles • Granite is a hard, coarse-grained rock. • Contains three main minerals such as quartz, alkali feldspar, and plagioclase feldspar. • Strong and durable. • The most size of granite used for domestic applications is 305x305x10mm. Travertine tiles are used as the flooring in the bathroom of the other bedrooms. It is suitable to be used as the flooring in the bathroom since it has a rough surface which prevents people from slipping over the floor. Granite tiles are used for the flooring outdoor. It is used widely as an elegant and many practical solution to design issues. FLOOR SYSTEM Taman Segar, Cheras, Selangor Darul Ehsan.
  43. 43. Wall structure is important for every construction as it carries the weight of the whole building. There are many ways to construct the wall based on the requirement of the client along with the design from the designer. Judging from our sites, we were able to learn more on the types of wall structure and how unique each construction is. There are 2 types of walls: Load-bearing wall (Site A and B) Load-bearing wall is a structural element. It carries loads from the roof and upper front floors and its own weight. This type of wall have to be able to resist side pressure from wind and sometimes imposed loads within the building. With trussed roof construction, external walls are known as part of load-bearing wall. WALL Non load-bearing wall A non load-bearing wall can be removed or altered. It is free standing and only carries own weight The wall is mostly built internally and is described as a partition. Being part of internal wall, piers and slabs are not required.
  44. 44. Material •Autoclaved Aerated Concrete (AAC) Blocks (SITE A) •Material was chosen for its greener advantages • Non-toxic and energy efficient as it consumes less energy in manufacturing process •Made from recycled aggregate •Good thermal insulation and low thermal conductivity •Made from a mixture of inert aggregate and cement (causes the formation of bubbles and expand around 5 times its original volume) and cured by natural weathering or in a pressured autoclave •Has a higher fire resistance •Has better water permeability, making it suitable for its site by being by the lakeside Mortar •Good workability •Adequate strength •A mixture of sand and lime or sand and cement with or without lime ratio and composition: Cement mortar (cement : sand) 1:3 — suitable for brickwork in exposed conditions such as parapets and brickwork in foundation. Lime mortar (lime : sand) 1:3 — for internal use only Gauged mortar (cement : lime : sand) 1:1:6 — suitable for most conditions of severe exposure; 1:2:9 — suitable for most conditions except those of severe exposure; 1:3:12 — internal use only WALL Clay Brick (SITE B) •A basic and cheaper alternative from SITE A, with contractor being more familiar with material •Used in general work with no special appearance •Type of brick used, solid clay bricks were used in site •Absorbs moisture easily thus plastering or rendering and finishing are required •Does not require skilled labour to assemble
  45. 45. Constructing a Brick Wall Lay a solid footer or foundation wall and then allow footer to cure for at least 2 full days before beginning to lay brick. is added to the Measure the two point as guideline to keep the wall centred. Mix the mortar according to the acquired ratio. Bricks are lay on the mortar. Starting from the second brick, mortar is applied to head joint end of each brick. Level is used to make sure bricks are levelled. When removing brick, trowel handle is gently tap on to avoid breaking the bond. SITE A •The use AAC bricks •Technique of using ‘thin-bed’ mortar is used making construction process to be skimming it. •Clay bricks are also used on site, creating man hole. It is done this way to save cost. SITE B •Mortar work is not neat as some parts the can drooling out. •Brick work is roughly done, with some bricks ‘popping’ out •Excess mortar isn't removed as plastering will be done later onto brick wall, avoiding any unwanted sight of brick wall. WALL A mortar line foundation. Hose the bricks down before beginning laying the brick to stop the bricks from absorbing moisture from the mortar.
  46. 46. Bond Running bond •Used in both Site A and B •Most common bond •Simplest pattern •Consists of stretchers only •Usually uses reinforcing ties to strengthen the bond because there is no header involved •Top level’s brick are placed 45 degree slanting upward in order to joint both wall and beam together as this is the solution to the lack of space that prevents using 2 layer of bricks. Rendering Give extra protection against penetration of moisture or to provide desired texture on the outside of the wall Process Wall is left for 3-5days to cure to for the first coat of render. Wet the wall thoroughly to prevent the bricks from absorbing moisture. Avoid rendering in full sun as the finish will dry up before it can be worked with. Mortar mixture is mix until acquired mixture is obtained based on client's need. Level pack is placed onto brick wall as a guide for the workers as a marking to indicate the plaster's thickness. Along with the angle bead, placed on the corner of the wall to ensure the vertical of the wall. Rendering, starts from the corner, working on combining the brickwork with the rubber grout float by filling the joints. After finishing the first coating, allow coat to dry. “Scratch" the plaster in a crosshatch diagonal design before the plaster cures making sure the first coat bonds well with the second coat. As for the second coat, it's not important to have a thick coat like the first coat, cause it's just as an additional cover. The number amount of coat depends on the designer, as to achieve the acquired wall. Process Dampen the wall before beginning the work as there is a risk of plaster drying up quickly resulting a friable and deleterious material Scratch coat (First coat) It’s important to wet the substrate. Because if plaster is applied to a dry masonry wall, the plaster will be dried quickly resulting in possibility of shrinkage cracks and delamination. Using hawk and trowel to apply the plaster to masonry. Fix level pack (ensure the plaster reach enough thickness) and angle bead at the corner of the masonry before plastering starts. Truing up takes place at the second coat. Scratch coat is to put material on the wall in preparation for the truing coat. “Scratch" the plaster in a cross-hatch diagonal design before the plaster cures making sure the first coat bonds well with the second coat. The plaster need 7 days to cure depending on the conditions, so second coat can be apply. Brown Coat (Second coat) Before applying the second coat, its important to control the suction. If the plaster dries out too fast proper bonding between 2 coats cannot take place. at least 7 days needed to ensure slow cure of the work. Finish Plaster (Third coat) The wall thoroughly dampen before finishing the plaster. Thin layer of plaster is applied using the "putting on and taking off" technique for 3 layers to have a smooth and flat surface. Ensuring a "tight" plaster with good bonding. And when the plaster is taking up, apply some water and polish the plaster with a trowel to have a soft glass like finish. WALL Internal Plastering Plastering is the mixture of gypsum with sand and water that provides durable hygienic surface to wall. Applying layers of mortar to masonry, wood, or metal lath will form a finished wall surface. The 3 coat work is where the background requires an extra coat of material and when the background is uneven, with the mortar not evenly spread during the brick wall process. Or background is lathing. The background has variety of different materials, using clay bricks, mortar and more.
  47. 47. Finishing Wall Tiling Using sand paper to smoothen out the wall, vacuum away the dust. A thin set of mortar layer onto the wall, using a tiling trowel to spread the mortar around the wall. First few tiles are installed along straight edge to ensure that tiles would not be crooked. Align the first tile along the edge of wall, then press it into mortar after making sure it’s straight. Process is then repeated. Excess tiles are then cut using machineries to fit into pattern. By marking the tile using a pencil, holding it up to the installed area. This is then repeated. When it’s done, installed wall are then left for 24 hours until the joint of the tiles are then grout. Type of grout is based on the requirement of the client. Excess grout are then cleaned out using sponge and water by gently rubbing it and often rinse. Painting Prepare the wall for the painting. By using sand paper to smoothen out the wall. Then vacuum away the dust. Wall is firstly covered with a coat of primer.. It help absorb the colour well. Start off from the edge of the wall and using an angled brush to help ease the painting. Roller is then used for the centre part of the wall. Wet the roller with different liquid for different paint based. Paint is then poured onto tray. Excess paint are rolled out on tray to achieve even coat. Paint is then left for hours to dry. Wall is then touched up using the second coat of paint. For wall at the roof or swimming pool where it is expose to water, waterproof membrane is applied to wall before painting. WALL Wood Veneer Ensure the surface of the wall is cleaned and smooth and then cut the veneer into specific shape and size by marking the cutting lines first and run painter’s tape along the planned seam. After cutting, remove the tape. This reduce breakage of veneer. Use glue roller to spread veneer glue onto the wall and also the backside of the wood veneer. Place the veneer on the surface and ensure that it’s set properly. Lastly gently apply pressure on the veneer to remove air bubbles. Aluminum Cladding Aluminum sheets are measured and drawn using pencil then cut using the aluminum panel cutter. Grooving and cutting the corner side of the panel to enable us to fold it. After being folded it will be caulked to stabilize the panel. Panels have been riveted interiorly, to secure it. Wall brackets, hold up the sheets and jointing the aluminum sheets together, being bolted on the wall. With galvanized steel tie hooked onto the aluminum sheets are then inserted into the hook from bottom to top. Apply force upward to secure the sheet onto hook. Sheets are bent 90 degrees to get the desired shape when sheets reach the edge of façade.
  48. 48. Introduction A stair is a structural consists of a numbers of steps leading from one floor to another. The main function of a stairway being to provide means of communication between the various floors for everyday use. As well as an escape route from upper floors in the case of a fire. A lot of measurements and calculations are required to be done when constructing the staircase as to allow maximum comfort for the users which includes a suitable width as well as step sizes. Types of Stairs Stairs come in the various following types : a ) Straight Stairs Stairs that has no change in direction on any flight between two successive floors. STAIRS Straight Stairs Stairs may permit a change in direction at an immediate landing such as parallel stairs, angle stairs, and scissors stairs. “L” Stairs Double “L” Stairs “U” Stairs Pie Stairs
  49. 49. b ) Curved Stairs Stairs that when viewed from above appear to follow a curve with two or more centers of curvature, such as an ellipse.. Curved Stairs c ) Circular/Spiral Stairs Stairs that when viewed from above appear to follow a circle with a single enter of curvature and large radius. A spiral stair is slightly similar to the circular stairs except that the radius of curvature is small and the stairs maybe supported by a center pole. Spiral Stairs STAIRS All the stairs present in both site A and B whether indoor or outdoor are all half-turn stairs but differentiate in material and aesthetic qualities.
  50. 50. Construction Process Prior to the construction of the stairway, several rules are established in order to make the stairs as comfortable to use as possible. a) All the risers in the same flight must be equal; the same rules apply to threads. b) Maximum height of riser is 8” and 9” for thread excluding the nosing. c) The formula Minimum R + T = 17” and Maximum R + T = 18” is the most common stair ratio being used. These rules being used better known as The International Residential Code which includes the change of allowable thread width and height of risers is updated every three years. Main stairways are usually not built or installed until after interior wall surfaces are complete and finish flooring or underlayment has been laid. The dimension for the stairs are then measured in order to find the accurate riser and threads. The stringer layout is first determined by the riser height being measured through the use of a story pole to mark the height of the top of the finished floor above. A straight piece of 2 x 10 or 2 x12 is then used to draw out the layout using the framing square with the riser height and the step is repeated until complete. The stair case in site A is a half-turn open riser stairs that rises up 3 story. The supports are first attached onto the wall following the initial measurements of riser and thread. The solid timber threads are then added onto the surface of the support followed by the black anodized carbon steel hand and guard rail. STAIRS Both stairways in Site B are concrete inclined, one-way reinforced slab with the addition of steps on the upper surface. After the measurements in terms of risers, thread and landing is determined through the general method as stated. The frame can then begin to be assembled.
  51. 51. When the form of the frame has been completed, concrete is then poured into it complete it’s basic structure for the stairs. The handrails and guardrails are then added to the stairs within the cast-in-place sleeve. Using stainless steel for the handrail and tempered glass for the guardrail as per design. Piece of cardboard are measured and cut to a exact size of the glass panels to be slotted into the in-cast sleeve at a later period. Half completed example of outdoor stairs on site B Completed example of indoor stairs on site B STAIRS Wooden thread is then lastly added onto the thread of the stairs as a finisher and adds to its aesthetic properties.

  56. 56. DOORS GENERAL INTRODUCTION A door is an opening or closing structure used to block off an entrance. Doors typically consists of a panel that swings on hinges or that slides or spins inside a space. It is held in position by doorframes, the members of which are located at the sides and top of the opening or doorway. The main function of a door in a building is to serve as a connecting link between internal parts and to allow free movement to the outside of the building. They admit people, animals, ventilation and light. Doors have many uses ranging from shutting out noise, to shutting out the atmosphere, to preventing fires from spreading, or simply separating two spaces. There are many different types of doors that would suit different functions and styles, depending on the type of building they are used in. Types of door found in Glenmarie Cove Klang Site 1 1. Double Leaf Hinged Door 2. Single Leaf Hinged Door 3. Sliding Glass Door DOORS Diagram 1: Anatomy of a door
  57. 57. Installing Door Frames and Openings For this site, the installation of the doors and doorframes were postponed until most of the construction is completed to avoid and prevent the woodwork from being damaged. The measured to detail openings were made as the brick walls were built and left to be fitted later with frames and doors. picture 1 - 2: Openings for doors during construction The head of a small opening like the one above is supported by a concrete lintel. It is to bear the load from above the opening. It is a structural horizontal block that spans the space between the two vertical supports. DOORS Diagram 2: Lintel sitting above door frame. Picture 3: Exposed concrete lintel
  58. 58. Alternatively, the head of any sized opening can also be supported from the floor above. This allows openings of any length. It requires the head to be aligned with the underside of the floor slab or beam above. This is the case for one of the openings in Site 2 (Cheras), as shown below. Door Opening in Brick Wall Construction Picture 4 - 6: Unfinished opening in brick wall after temporary timber struts are removed. DOORS In this case, the opening goes up to the beam (full height of the floor). To hold up the temporary timber formwork in position during the following building operations, the workers use struts. These are braces against blocks on the ground and lean up to the head of the frame, where they are secured with two nails. The temporary formwork to make the opening are cut to finished size and sanded. Nails are used to assemble the temporary door frame which is then is raised into correct position. Bricks are then laid up to the frame on each side. Diagram 3: Temporary formwork and struts for door opening construction
  59. 59. Once the bricks are laid and the wall is done, the struts and temporary timber frame is removed. The brick wall is cemented and tiled with bathroom tiles on one side. Full size tiles are laid leaving the access to be cut off later. picture 7 - 9: Temporary timber door frames A doorstep is then made with cement and tiled. When the access tile is cut and the opening is cleaned and ready, a selected door with its frame is chosen and installed. For this opening, a hinged door would most likely be used. DOORS Picture 10 -11: Bathroom tiles before excess is cut The installation of the frames is postponed until most of the construction is complete in order to reduce the risk of damage to the woodwork. As seen in the picture above, temporary timber door frames were used for most openings throughout the construction process until the door frames and doors were ready to be fixed.
  60. 60. Timber Frames for Openings A door frame provides a secure attachment for the door. Depending on the type of door, its function, and its location, different types of door frames can be constructed. The most common door frame consists of three members; Two posts (a) One head (b) One member on the floor, called the threshold (c) Diagram 4: Members of a timber door frame However, there were also openings in the house that were just timber frames with no doors. For these frames there are no door jambs needed as no door is needed. DOORS Picture 12 -13: Openings with Casings only
  61. 61. Hanging an Internal Hinged Door • Once an opening in a wall is ready, the door frame and door can be fixed. A simple timber door frame, painted in white, is used for all the hinged doors found. • A hinge is selected according to the size and weight of the door. The height and distance between each hinge is measured before it is screwed to the frame. • The top hinge is marked 6 inches (150mm) down from the top and the bottom hinge 8 inches (210mm) up from the ground. The hinges are placed inside of the markings and a pencil is used to draw around the hinge. • The hinges are then screwed on and made sure and the hinges and screws are flush. The door is then propped up into the frame while resting on wedges and not on the ground so that there is a correct gap at the bottom. Once the markings are made on the door frame, a single screw can be used to fasten the door first so that adjustments can be made later. Picture 14: Entrance door hinge Diagram 6: A dissembled hinge Diagram 7: Hinge when the door is closed DOORS Diagram 5: An assembled hinge DOORS For most doors in residential construction, the residential grade butt hinge is adequate. It s neat looking and consists of two rectangular leaves with screw holes. The leaves are joined by a pin. Withdraw this pin and the leaves will separate. Both leaves are recessed; one into the door, the other into the jamb or framework. When the door is closed, the leaves meet, as shown above, with only the pin showing.
  62. 62. Types of doors found in Taman Bukit Segar Site 2 1. Sliding Doors (Interior Sliding Glass Door) 2. Bi-fold Sliding Door. 3. Hinged doors for entry, store rooms, bedrooms, and smaller spaces. 4. Timber top-hung sliding door for wardrobe. 5. Openings only (with timber frame). Interior Sliding Glass Door The mechanism used to operate a sliding door is called sliding door gear. The first type of sliding door found on site is a bottom rolling system sliding door. When the weight of the door cannot be supported from above, a bottom rolling system is used, such as in this case. DOORS This system consists of two rollers at the bottom of the door, running on a track, and two rollers at the top running in a guide channel. All the weight of the sliding door is concentrated on the bottom two rollers, therefore more force is needed than on a top hung system. DOORS picture 14: Bottom tracks of the sliding door
  63. 63. To be more specific, a sliding glass door, as shown in the picture above, is a large framed glass in a structure that provides door access from room to room or to outdoors. There are two types of sliding glass doors found on site: i) 2 panel sections ii) 4 panel sections In a two panel section sliding glass door, as sketched below, one panel is fixed while the other is mobile to slide open and close. In a four panel section sliding glass door, the two outer panels are fixed, while the inner two are mobile to slide open and close. Picture 15: 4 section sliding glass door Assembling and Installing a Sliding Door •When installing a sliding door, there are two situations; the first being the sliding door is readily assembled and the other is having to assemble it on site. • An opening in the wall would be cut or made to size. Once the opening is done, a header is placed above the opening. If the opening is made directly under a beam, this is not necessary. •A timber frame was used in this case and was lifted and set into the opening. A nail gun was then used to nail the top right side or the frame then the flanges. Advantages of Sliding Doors 1. Sliding doors let a lot of sunlight in while being aesthetically pleasing. 2. Saves a lot a space as it does not require any space except for the opening. 3. Can see through from room to room or indoor to outdoor. 4. Also, creates the illusion of more space. 5. Allows larger objects to be moved in and out of the home or rooms. DOORS •Wood shims are then used and shoved into any small gaps to make sure the frame is level and has right angle corners. Once the opening is done and ready, the assembled sliding door and frame is lifted and fit into place. The sliding door will be secured with 12 inch screws. Lastly, the shims are trimmed and the timber frame is covered with cement or plaster and painted.
  64. 64. Bi-fold Sliding Door or Bi-folding Door Picture 16 - 18: Opened and closed Bi-fold sliding doors used on site The bi-folding doors on site have a white aluminium frame. There are two types found; i) Four Panel Sections ii) Eight Panel Sections A bi-fold sliding door is a type of door that opens by folding back in sections, while sliding to the side. On site, they are used as entrance doors, separating indoors from outdoors. They are designed to provide quick and easy space division. Advantages of Bi-fold Sliding Doors 1. Allows maximum or 100% clear opening. 2. Keeps doors out of the way and safe for children to run in and out. 3. Lets more air for ventilation into the house. DOORS Diagram 8: Showing how a bi-fold door slides open
  65. 65. Top-hung Timber Sliding Door This single panel, top-hung sliding door is used on site for all the bedroom wardrobes. It uses the tophung system and the door is hung by two trolley hangers at the top of the door, running on a concealed track. All the weight is taken by the hangers therefore making it easy to move. There is not track at the bottom of the sliding door and there is a slight gap between the door and the floor to ensure there is no friction and obstruction in its mobility. Picture 19 - 20: Opened and closed top hung sliding door There is a track stopper or door stop at each end, as shown in the picture below, to absorb any impact if the door is slammed and to hold the door in an open or closed position. Diagram 10: Longitudinal section through tracks at the top of top hung sliding door. DOORS Diagram 9: Section cutting through tracks at the top of top hung sliding doors
  66. 66. Picture 21: Showing position of the plastic floor guide DOORS In most cases, a top-hung system also requires a guide at the bottom to prevent the sliding door from swinging sideways. In this case, a floor-fixed plastic guide is fixed below the door at the mid-point of its run (marked in the picture below), and a groove is cut into the bottom of the door which runs over this guide. This prevents any lateral movement. Because the door is always engaged in the guide, when the door is open the floor is clear leaving a clear threshold.
  67. 67. Hinged Doors These doors are hinged along the side to allow the door to pivot away from the opening in one direction but not the other. There are no swing doors that are also hinged doors, on site. There are four types of hinged doors found on site; i) Timber Bedroom Door (Single Leaf) ii) Timber Entrance Door (Double Leaf) DOORS iii) Maid’s Room Door (Single Leaf) iv) Store Room Door (Double Leaf)
  68. 68. Hardware, Fixtures and Fittings The various fixtures used are: 1. Hinges 2. Bolts 3. Locks 4. Handles Door Handles It is an attached mechanism used to open or close a door. The keyhole is located below the handle. Door Handle This is an interesting type of door knob which can be pushed in and out to open and close the door. Door Hinge Strike Plate Lockset and keyhole It is a metal plate affixed to a door jamb with a hole or holes for the bolt of the door. When the door is closed, the bolt extends into the hole in the strike plate and holds the door closed. This consists of components that comprise the locking or latching mechanism that can usually be found on a door or other hinged object but can also include sliding doors. DOORS This is the hinge used for the bedroom doors. It is shorter than the ones used for the heavy timber entrance door which has 5 screw holes. It is the device that allows the turning or pivoting of the door.
  69. 69. Window System The windows of houses in Site A and Site B have been installed by using sub-frame system. Window type Sub-frame system Pro - Lug system - More stables To minimize damage during construction stage Sub-frame can be installed before the main frame is readily available. Hence, speed up the construction Cheaper Conventional Con More expensive compare to cast in system and lug system - Extra care is needed to avoid damages during construction stage Head Lintel Jamb Sash Sill Figure 1: Early Construction Stage No. Figure 2: Complete Installation of Fixed Window Explanation 1 Rough opening Space is required at the top sides, and bottom for leveling and shimming of the unit 2.

  76. 76. Ventilation Ventilation of a building will be affected by size of window and type of glass used. Insulating glass in Site A and Site B consistes of two or more sheets of glass separated by a hermetically sealed air space to provide increased thermal insulation and restrict condensation. Clear insulating glass without tinted and coating in Site A and Site B can reflect 14-15% visible light and 11-15% solar radiation (Francis DK Ching 2008) Windows Type Ventilation % Fix window 0% Top hung window 100% Sliding window 50% Frameless window 0% WINDOW The position of a window will be concerned according to different zone such as toilet.The windows in toilet are usually installing at higher position at the wall. This is to conduct ventilation and reduce visibility from outside at the same time.
  77. 77. ROOFS SITE 1-KLANG GENERALINTRODUCTION The roof system functions as theprimary sheltering element fortheinterior spaces ofa building. It usually controls theflowofwater aswell asthe passage ofwater ,air,heat andcold .Similar tothefloor system, aroof must bestructured to span across space and carry both itsweight and liveloads such assnowand wind .itsstructural layout musttherefore correspond tothat ofthewall andcolumn systems through whichits loads are transferred downtothefoundation system. THE FOLLOWING TABLE SHOWS THE ADVANTAGES AND DISADVANTAGES OF USING A FLAT ROOF ADVANTAGES: DISADVANTAGES: They are very easy to put up They lose heat They can create extra usable space if they are accessible They are not as weatherproof as pitched roofs They are easily maintained The finishes do not last as long as roof tiles In the construction process, the thermal insulation made from metal sheathing is laid beneath the roof deck, allowing the roof and structure to be insulated from extremes of temperature, such as heat that enters into and out of the building .The insulating metal sheathing also prevents the water entering into the roof during rainy weathers. The roof is made slightly stiff , to avoid any wind uplifting forces . The deck slopes towards the gutter or drainage points at an angle which is sufficient enough to drain the water that falls onto the roof. FALL SHOWN AT AN ANGLE SUITABLE ENOUGH TO DRAIN RELIABLY ROOF Structure of flat roofs a deck or slab a method for disposing of rainwater a watertight covering some insulation
  78. 78. Assembling of truss After the layering of the sheathing , there are battens placed to provide fixings . The assembling of the flat roof is very simple as a roof truss is hollow and is made from steel . It is connected to one end of the structure . This causes a slant for easy water flow . The other end of the roof is laid flat like a beam . The truss is connected using roof brackets . The truss is connected to the columns of the building using a clip , which is nailed to the top of the wall , it turns up at 90 degrees to the truss with a slot in it . The metal roofing used can resist high winds and stimulates other roofing materials. METAL TRUSS ROOF TRUSS SHOWING BRACE BRACKETS USED FOR CONNECTING TRUSS TRUSS ARRANGMENT OF THE FLAT ROOF TRUSS AND COLUMNS CONNECTED CLIP USED FOR CONNECTION ROOF The roof is covered or finished by metal sheets , which act as membranes whose purpose is to waterproof the roof area . This makes it easier for the water to run off from a slight inclination to the terrace , which allows flow to the gutter. Below the truss , there is space made for an eave , which overhangs from the roof . Hence it is known as an eave overhang . The overhang ensures that when it rains , the walls of the building are not wet or affected by the water that comes down . It also can be seen as a channel for water that is being sent to the gutter . There is placement of a fascia board along the roof , it holds the gutter in place.
  79. 79. SKYLIGHT CEILING The ceiling of the second floor is a that of a skylight ceiling . It is made from tempered glass and is supported by metal beams . The use of tempered glass is because , if in any case the glass shatters , it will not be injurious , as the glass remains intact . It will appear as though it is just cracked . The 2 piece laminated glass is 12 mm thick(each).With a frame of 50mm.It allows light to pass through into the house . It is visible on the terrace floor . Again ,it is raised to allow flow of water towards the drain holes. For most of the ceilings inside the toilet , there are ventilation tubes and outlets placed . They are held in place by metal beams . After this the ceiling and walls will be plastered . These vents permit the septic gases to escape to the outside and allows fresh air into the system. For most of the ceilings inside the toilet , there are ventilation tubes and outlets placed . They are held in place by metal beams . After this the ceiling and walls will be plastered. DRAINAGE DETAILS WITH FILTER CAP A B AS SEEN ON THE ROOF The terrace flooring is made to slope at an angle , to allow flow of rainwater into the gutter. On the terrace , there are drainage systems placed for the flow of water . They are made from plastic , and are placed vertically . Due to construction purposes and safety purposes they have not been cut to their suited height . This is because , there could be chances that they may have to be connected to another drainage pipe coming from the bottom of the building. However after completion , they are meant to be standing at a height of 50mm.They will be covered with filter caps to prevent any dirt or objects falling through , as seen in the picture. Flow of water on a flat roof (A) Section of a drainage pipe with a filter cap(B) ROOF AS SEEN FROM THE INSIDE
  80. 80. PITCHED ROOF SITE 2 –CHERAS The main supporting structure is made from steel . The truss is a triangulated plane roof frame. A pitched roof is stable in most weather and its slope disposes of rainwater. An advantage with this kind of roof is that the space enclosed by the roof can add some extra living or storage space. The roofs are pitched roofs with a square and rectangular base respectively. COMMON RECTANGLE BASED PITCH ROOF SQUARE BASED RECTANGLE BASED The pitched roof affects the structural design: Span-the span is the distance between the masonry structures that support the roof. Pitch-the angle of the slope of the roof measured from the horizontal. Roof covering-the roof covering material varies from light weight sheets. After laying the under lays , most of the vents and pips were placed , to avoid any unwanted leakages. The roof under lays provide the barrier to the entry of wind , rain , even snow blown between the tiles or slates, It also prevents the entry of water. The use of bitumen sheets are being used , as they are permeable to water vapor and do not need to be perforated to ventilate the roof spaces. THE TRUSS IS CONNECTED TYPICAL TRUSSED RAFTER DETAIL CONNECTING THE TRUSS The use of gang nail plates help to secure the truss together . These are often used to secure wooden trusses . The Gang Nail Plates are made from galvanized steel and have projecting nails . They are placed across the truss members to be connected and the nails are forced in under pressure . A plate is put on each side of the joint. On site , bearings were made and the purlins were screwed onto the roof trusses . Gables were erected and braced to avoid any lateral movement. GANGNAIL PLATES USED FOR CONNECTING THE TRUSS(WOODEN TRUSSES) ROOF TRUSS FORMATION The roof is constructed using the trussed purlin roof method . The trusses replace struts as support for the purlins . Trusses , which are spaced about 1200mm apart , are braced against the external walls rather than internal load bearing walls.
  81. 81. Roof eaves The roof eave is made from timber strips or fascia boards . The ceiling inside is made from plaster which is made up from mortar and fine sand. The eaves being the lower borders of the roof, are horizontal and overhang the walls and casts off the water that falls on the roof. Roof eaves protect the brickwork from rain and supports the wall. Using tiles as roof coverings There are two layers of tiles covering any part of the roof . Each tile has at least two nibs on battens nailed over the rafters . The two nail holes provide the means of fixing the tile to the batten. The type of tiles used on the roof are known as “tile and a half tile”. The roof tiles are made from clay or concrete that are molded into suitable shapes . Their main function is to keep the roof watertight as well as enhance the appearance of the roof. The tiles are overlapped so that the rain water flows down the slope of the roof and the roof structure underneath remains dry . The tiles are fitted closely together to prevent wind entering the spaces between them . Since there is a possibility of rain water that can be driven underneath the tiles , a layer of polythene is inserted over the rafters . Hence if water flows through the tiles , then it will flow down this layer into the gutter. The tiles are inserted . They have nails at the top so they can be nailed to battens. Layers of reflective insulation made up of double sided highly reflective metal polyester are used to keep out the rain and wind while the tiling work is done during construction . The tiles are placed in regular bond patterns , so that the edge joints between the tiles are in the centre of the tiles immediately below and above the course under consideration. ROOF Lightening Arrestor Lightening arrestor is a device placed on the top of the roof to protect the insulation and conductors of the system from the damaging effects of lightening . Its main function is that of insulation . And to avoid any effects of lightning as the space is open. Gutter and Drainage The roof is designed with a suitable fall towards the surface water collection channel or gutter which in turn is connected to vertical rainwater pipe which conveys the collected discharge to the drainage system. The material used for the eaves gutters and rainwater pipes is cast iron but uPVC systems are also being used because of their simple installation and low maintenance costs . The materials used are of adequate size , strength and durability. ROOF DRAINAGE SYSTEM GUTTER BOXES USED AROUND THE EAVE AND ROOF
  82. 82. THE FINAL DISCHARGE OF WATER IS DIRECTED TO THE BOX DRAINAGE PIPE. The gutter is that of a box gutter which is within the eaves of the roof . The gutter continues under the foundation and leads to a drain passage(as seen).The drain passage is going to be covered after complete construction , to avoid a “messy” look . Another advantage of this type of gutter as shown in the picture is that , when the water flows down the drain , it reaches the drain passage and does not allow excess water to flow by the doors , so as to cause puddles of water. . Gypsum Ceiling Board Firstly, ceiling panels is installed first, then the wall panels. Constructing the ceiling grid, using the steel brandering and form a perimeter around room. Once board is cut to size, position gypsum boards into place without forcing them. Similar edges and ends, like tapered to tapered, square-cut ends to square ends are matched and put together. Span the entire length of ceilings or walls with single boards if possible to reduce the number of butt joints, which are more difficult to finish. Stagger butt joints and locate them as far from the center of the wall and ceiling as possible so they will be inconspicuous. Using the screw gun to drives all types of gypsum board screws through gypsum board and into framing or substrate. For a single-ply application, position all board ends and edges over parallel framing members to ensure that the joints are supported. Whereas in a two-ply assembly, with adhesive between the plies, the ends and edges of face layers need not fall on supporting members. Using a temporary T-brace to support the weight of the ceiling . Mechanical and electrical equipment should be put into consideration at all times, at the proper distance relative to the framing to allow for the gypsum board thickness so that the trim components, such as cover plates, registers, and grilles, fit correctly. It is dangerous for the depth of electrical boxes to exceed the framing depth and avoid placing boxes on opposite sides of a wall in the same stud cavity space. ROOF / CEILING Ventilation Outlets , these are placed on the roofs between the tiles right above the toilet under in the house
  83. 83. Conclusion With this project we were able to understand the basic procedures and profile of construction process through real life project, by exposing students to construction technology and method responding to site context. With Site A as a private triple storey bungalow in Glenmarie Cove, Klang. Offering a green view as it's at the lakeside. While Site B, a private property with 13 unit of triple storey bungalows, offers an overview of the hill which is filled with residential houses, Bukit Segar. Even when both located in different site, they use the same type of foundation, deep foundation. From the roof, we can learn two contrasting genre of roof, Site A using the unique flat roof where we can hardly see this type of roof based on Malaysia's climate. And Site B uses the classic pitch roof. In bricks, Site A uses AAC bricks as it help ease up the installation of the aluminium cladding, while Site B uses solid clay brick as part of their wall system. Huge contrast can be seen in the construction of stairs as even though both uses half turn stairs as part of their design, Site A used the concept of open riser with timber as their medium. Whilst, Site B uses concrete stairs with wooden thread. Sub frame was used as their window system, this applied to both site. From both construction site, we were able to understand construction technology on local construction sites based on the unique climate in Malaysia. Enabling us to comprehend the current material and technology in relevance to present construction industry. BUILDING CONSTRUCTION HANDBOOK, Sixth edition, R . Chudley, MCIOB and R.
