  • 3.3 Earthwork Types of Earthworks Earthworks can be calssified based on the tyoe of excavated material: Removal of the exposed layer of the earth’s surface, including vegetation. Since the topsoil, or mantle soil, supports growth of trees and other vegetation, this layer contains more moisture than that underneath. Removal of a formation that cannot be excavated without drilling and blasting. Any boulder larger than 1⁄2 yd3 generally is classified as rock. Rock Excavation: Topsoil Excavation: Removal of material that contains an excessive amount of water and undesirable soil. Its consistency is determined by the percentage of water contained. Because of lack of stability under load, muck seldom can be used in an embankment. Removal of the layer of soil immediately under the topsoil and on top of rock. Used to construct embankments and foundations, earth usually is easy to move with scrapers or other types of earthmoving equipment.

  • 4.1 Introduction to Foundation Foundation is the lowest part of the building. The first function is to support the building and anchor the superstructure above and transmit its loads safely into the earth. Foundation system must anchor the superstructure to prevent the wind- induced sliding, uplift and overturning withstands the sudden ground movements of an earthquake then resist the pressure imposed by the surrounding soil mass and ground water. Proper designed construct foundation As the building is constructed, some settlement is to be expected as the load on the foundation increases and causes a reduction in the volume of soil voids containing air or water Anchorage to resist sliding, uplift and overturning Foundation Differential settlement Substructure FOUNDATION Prepared By: CHRISTIODY
  • 4.1 Types of Foundation systems Foundation have a lot of combination of bearing walls, columns and piers to transmit building loads directly to the earth. There are some structural elements can form various types of substructures, such as, basement wholly , crawl spaces, concrete slabs on grade and a grid of independent. Two types of foundation systems are Shallow foundation and deep foundation. Basement wholly Crawl spaces Shallow Foundation Concrete slabs on grade A grid of independent Shallow Foundation Deep Foundation FOUNDATION Prepared By: CHRISTIODY

  • 5.1 Column & Beam Advantage of Reinforced Concrete Column: • It has a relatively high compressive strength; Advantage and Disadvantage of Reinforced Concrete Column • It has better resistance to fire than steel; • It has a long service life with low maintenance cost; In some types of structures, such as dams, piers, and footings, it is the most economical structural material; • It can be cast to take the shape required, making it widely used in precast structural components. It yields rigid members with minimum apparent deflection. Disadvantage of Reinforced Concrete Column: • It has a low tensile strength of about one-tenth of its compressive strength; • It needs mixing, casting, and curing, all of which affect the final strength of concrete; Pictures shot during site visit • The cost of the forms used to cast of concrete placed in the forms; • It has a low compressive strength as compared to steel (the ratio is about 1:10, depending on materials), which leads to large sections in columns of multistory buildings; • Cracks develop in concrete due to shrinkage and the application of live loads.

  • 5.2 Slab Step to Construct Column Diagram 1.5 : 1. Wooden panels were set Cement up to form the shape of the slab. Besides that, the rebar is placed on the Rebar gravel to withstand more force. 2. Cement is poured into the wooden formwork to form reinforced concrete slab. Wooden panel 3. Remove the wooden 2 1 panels after the cement form slab shape and it takes time around two weeks. 4. Reinforced concrete slab Wooden panel 3 is totally dried up around 28 days. 4 SUPERSTRUCTURE Prepared By: DANIEL YAP CHUNG KIAT
  • 5.2 Slab Advantage of Reinforced Concrete : • Reduced project time & Improved Cash Flow • Shorter start to finish time Reason of concrete crack: Shrinkage, Rapid Drying of the concrete, Improper strength concrete poured on the job. Prevent slab from crack : Know the allowable water for the mix the contractor is pouring- or be very sure you have chosen a reputable contractor who will make sure the proper mix is poured. It is more expensive to do it right- it simply takes more manpower to pour stiffer mixes. SUPERSTRUCTURE Prepared By: DANIEL YAP CHUNG KIAT
  • 5.3 Wall Constructing a concrete brick wall:Brickwork bond used on site: Stretcher bond (Running bond) Types of bricks used on site:Clay brick and Cement sand brick Features: Most common bond  Easy to build  Produces very little waste  Use for interior setting because of its thin wall Step 1: Foundation Pour a concrete foundation if you do not have an existing slab, brick ledge, or footing to work on. Concrete footing A wall is a vertical structure, usually solid, that defines and sometimes protects an area. Most commonly, a wall delineates a building and supports its superstructure, separates space in buildings into sections, or protects or delineates a space in the open air. Soil Wood board (formwork) Aggregate s Perspective view SUPERSTRUCTURE Prepared By: LOO GIAP SHENG
  • 5.3 Wall Step 2: Measure the brick get the length of your wall Start by putting a brick down at each end of where you want the wall to go. Measure the size of your brick because bricks come in variety of sizes; long, short, wide, skinny, etc. 9 5/8” Step 4: Consistency Spirit level 3/8” Keep the height of all bricks the same by using a spirit level or carpenter’s level. Check them once in a while to be safe. 10” For example if your brick is 9 5/8 inches long, then you may want to mark 10 inches intervals for each brick. The remaining 3/8 inch gap you can fill them with mortar. Step 5: Next level brick Always start at each end then fill in the middle till you get to your destined height. Remember to adjust your hook line every level you goes. Step 3: Set up the line Hook a line at both ends so it lines up with the very top of the two bricks. Then fill up the middle. Half size brick Full size brick Set up the line Fill the middle SUPERSTRUCTURE Prepared By: LOO GIAP SHENG
  • 5.3 Wall Step 6: Wiring and piping Constructing a drywall partition wall After constructing the brick till the top, you have to get all kinds of piping ready depending on what you need: wire, air conditioner, water and etc. Then, you need to craft a cylindrical-like space on the wall vertically or horizontally depending on your piping system. Then, you can start setting up your pipes. Advantages: Easy and fast installation  Fire resistant (contains gypsum)  Superior in terms of insulation  Environmental-friendly Cylindrical-like space for pipes Step 1: Mark and record Determine where you want to place your partition wall and on the spot, put a mark on the ceiling. From the mark, drop a plumb bob and mark the floor. Repeat it on the other side where the partition wall going to end. Step 7: Laying the mortar Before you start to lay the mortar, construct a small flat-topped pyramid with mortar at every corner and side end (make sure they are all same height). This method is use to make sure the mortar is laid perpendicularly. After the flat-topped pyramid mortar has dried, you can now finish off by laying the rest mortar on the wall. Flat-topped pyramid mortar Plumb bob SUPERSTRUCTURE Prepared By: LOO GIAP SHENG
  • 5.3 Wall Step 2: Measure and cut Step 3: Assembling the pieces Prepare studwork timber to make the frame of the partition wall. Using measuring tape, measure and dimension the size of the wall you want it to be. Note that the distance between every stud has to be in 16 inches because:- Lay the cut studwork timber on the floor first then proceed by joining them together. Drive two 16d nails into each edge at 45 degree angle. This method is to make sure the studworks are firmly attached.  The standard dimension of heat and sound insulations are 16 inches as it could fit exactly into it.  By the time it comes to time, you might want to put things outside the plasterboards such as baseboard, crown mold, cabinets and etc. It is good to know where the studs are for nailing and screwing purposes. Nail at 45 degree Cut the studwork timbers using a saw into the dimension (according to the size of your wall) shown below:Top plate Step 4: Screw the plasterboards Studs Cut the plasterboard of that size of the outer frame. Screw the plasterboard in, at only one side of the frame. Noggings Maximum 1350 mm 16 ” Base plate SUPERSTRUCTURE Prepared By: LOO GIAP SHENG
  • 5.3 Wall Pre-cast wall Step 5: Install insulations Leave the other side of the wall empty so that you can place the insulation in. Make sure you install the right type of insulation depending on what you need: heat, sound, or both. Measure and cut the insulation into the right size so that it fits exactly. Heat/sound insulation Advantages: Rapid construction  Good quality control  Minimal wastage Disadvantages: Limited building design flexibility  Skilled workmanship is required on the site  Connections are difficult Step 1: Plotting the wall element Mark the outline of the wall with the dimensions you want. Step 6: Finish the plasterboards After inserting all the insulations you want, cover them with plasterboards. Again, cut the plasterboard of that size of the outer frame and screw the plasterboard in. Step 2: Moulding and placing electric/water installations Place the electric and water pipes on the mark (depending on what you need). SUPERSTRUCTURE Prepared By: LOO GIAP SHENG
  • 5.3 Wall Step 3: Inserting reinforcement (ironing) Step 5: Vibration and rotation (double wall formation) Insert iron bars within the outline of the wall. After the mortar has dried, rotate the dried mortar and stack it with another prepared wall. Step 4: Concrete filling Step 6: Storing the walls Pour mortar onto the iron bar. Hook the wall off to a side as it is available to be cast to construction SUPERSTRUCTURE Prepared By: LOO GIAP SHENG
  • 5.3 Wall Reinforced concrete wall Step 3: Removing forms Features: Higher relative strength  Used in skyscrapers and bridges  Have expansion joints to prevent cracking in response to changes of temperature Step 1: Setting steel and inspection After the mortar has completely dried, remove the formwork. Set up the skeletal structure with steel bars. Step 2: Formwork and mortar Glass block wall Advantages:    Transmit light in both direction Distorting image to create privacy Resistance in heat, sound and impact Cost effectiveness (minimal maintenance) Set up the formwork and pour mortar into the formwork. SUPERSTRUCTURE Prepared By: LOO GIAP SHENG
  • 5.3 Wall Step 1: Determine the number of blocks Measure and plan your project as glass block cannot be cut. Do not forget the thickness of mortar joints. Step 3: First row Step 5: Complete wall Lay a bed of mortar and start placing the glass blocks. The spaces between the end of the block will be filled with expansion strip instead of mortar due to climate changes. Continue laying the glass blocks until the top. Remember to add panel anchors in every two rows to increase its endurance. Expansion strip Step 2: Prepare mortar Mix an amount of glass mortar depending on your usage. Step 4: Second row Repeat step 3. After filling the second row, place panel anchors on the glass blocks and screw them into the side wall of both ends.

  • 7.0 Roof Roofing Introduction A roof is the covering on the uppermost part of a building. A roof protects the building and its contents from the effects of weather and the invasion of animals. In most countries, the roof protects primarily against rain, heat, sunlight, wind, cold and snow. Introduction to Butterfly Roof A roof shape which has two surfaces that rise from the center to the eaves with a valley in the center; resembles the wings of a butterfly. The butterfly roof design is not only meant for the good looks but also have some advantages, the interiors of the house feels very airy and fresh. It also allows more sunlight to enter the house due to increased height of walls. Besides, it forms a v shaped valley so the roof is capable of storing rainfall. However, leakage problem makes the butterfly design less comfortable, it requires a little bit extra maintenance than other roofing, which is the main reason why butterfly roof is less popular.

  • 7.1 Butterfly Roof and Shed Roof (on site) Modern Construction Method Step by step 2 1 Roof Truss: Sloping Top Chord Roof Framing These metal trusses are pre-fabricated in a factory and delivered to site ready for fixing, much simpler than traditional roofing carried out entirely on site. The purpose of a roof frame is to provide a structure that spans the walls of the building and supports the roof covering. The slope of pitch is to allow rain water to run off and be drained away from the dwelling. The roof frame also assists in bracing the structure from wind forces from various directions. 3 4 Install Acoustic Insulation Panel on top of Roof Framing Roofing insulators that prevent heat flux through the roof, they are set below water proof roofing materials. Flashing: Install Corrugated Galvanised Steel Roofing on top of Insulation Panel pieces of sheet metal usually lead, attached around the joints and angles of a roof to protect against leakage ROOF Prepared By: NG YOU SHENG

  • 7.2 Types of Roofs The gambrel roof is the variation of a gable roof. It has a steep slope on two sides , a second slope begins partway up and continues to the top. This type of roof is commonly used on barns. The gable roof has two sloping sides that meet at the top to form a gable at each end. It is the most common type of roof. GABLE ROOF GAMBREL ROOF The gable roof has two sloping sides that meet at the top to form a gable at each end. It is the most common type of roof. The hip roof slopes at all sides, results in an even overhang all around the building. It is a very strong roof and is commonly found in regions where have severe storms. This roof is very popular due to its low maintenance needed. HIP ROOF MANSARD ROOF ROOF Prepared By: NG YOU SHENG
  • 7.2 Types of Roofs A-Frame Roof is normally used in countries which have snowfalls, the steep slope allows the snow slides to the ground instead of remaining on top. A-Frame house have limited space and are usually built as vacation cottages. Curved roof is known for their aesthetic appeal. Other than that, it may allow for greater indoor areas or extra floors where height restrictions are a concern. In addition, a curved roof may also help to reduce resistance to wind. CURVED PANEL ROOF A-FRAME ROOF The flat roof is not perfectly flat, the rafters are laid at a slight angle to allow rain water to flow. Sheathing and roofing are applied to the top of the rafters. Shed roof, also called a lean-to roof, the shed roof is often used for an addition to an existing building. A shed roof is similar to a flat roof but has more pitch.

  • 8.0 Summary Although both site A and site B are three-storeys building, but we found that the construction process of site B is much efficient. In our opinion, site B uses more advanced machines and the land area is operated by developer. From our observation, the workers in site B are more skilled and attentive compared to site A. The superstructure of site B can be pre-casted because it required less design flexibility. SITE A (Bungalow house) SITE B (Shop houses)
