    • 1.0 Introduction As architects and the building industry continue to design and build structures that differ in design, type, materials and building method, it has become important that each party stay familiar with both basic and new concepts of building construction. As time pass by, construction methods are constantly being replaced by new and more efficient and cost effective methods to construct buildings. Therefore, architects need to improve with knowledge of building construction in order to follow trend of technology.   AIM : This project is to produce architects with knowledge of building construction by identifying difference types of building elements, construction process, details and materials. This report includes the studies and records of site and safety, external work, foundation, superstructure, roof and doors.

    • 4.0 Foundation 4.1 Foundation type and construction process     A pile cap is a thick concrete mat that rests on concrete or timber piles that hav e been driven into soft or unstable ground to provide a suitable stable foundati on. It usually forms part of the foundation of a building, typically a multi-story b uilding, structure or support base for heavy equipment. The cast concrete pile c ap distributes the load of the building into the piles. A similar structure to a pile cap is a "raft", which is a concrete foundation floor resting directly onto soft soil which may be liable to subsidence. 4.after the completion of a bored pile , the remaining reinforced bars are then extended to form starter bars and th e concrete pile is then extended up to ground level or beyond such that the floors of the building rests on the pile.
    •                 5.1 Beam & Column   Beam and Column       •  Reinforced concrete column       •  •  •  •  Length of overlapping reinforcement bar is forty times of the diameter of bar. Dowels tie column to supported beam or slab. Vertical reinforcement should not be less than 1% nor more than 8% of the cross sectional concrete beam. Types of reinforcement steel includes T12, T14, T16, T20, T25, T32 and T40. ‘T’ represents reinforcement steel and the numbers indicates the diameter. Lateral Reinforcement 1. •  •  •  Reinforced concrete column is designed to carry compressive load. Reinforcement bar in concrete increases the column’s tensile strength. Size of columns differs according to the amount of load it has to bear. •  •  •  •  •  •  Rebars for columns 2. 3. 4. Number of reinforcement bar used in columns may be varied instead of varying the size of columns. Formations of lateral reinforcement bars depends on the number of vertical reinforcement bars used in a column. Lateral ties should have a minimum diameter of 10mm. Space between two ties is not more than 48 tie diameter. Type of reinforcement used is usually T12, reinforcement steel with a diameter of 12mm. Concrete columns may be supported by isolated footings or by pile caps.

Treads and risers on the panel are also laid out. Then, the slab thicknesses at a right angle to the slope of the stairway are measured and a line is snapped.       Figure  5.5.1:  Staircase  construction   formwork  at  Altitude  236   Shores to be cut at angle After that, lay out the soffit panel thickness, joist width and stringer width and snap lines. The next step, shore length and the side form width are determined.                                         4   Soffit panel Stringer width Brace Riser STAIRCASE Shores cut to length Shores are cut to length and secured in position. Stringers are nailed to the tops of the shores, joists are nailed to the tops of the stringers and soffit panels are nailed in position. Then, the temporary panels are removed. NOTE: The construction of stairs using system formwork at Altitude 236 is very similar to wooden formwork such that segments of the formwork are pieced together like a jigsaw. System formwork is at an advantage whereby no wastage of wood is produced and the aluminium mould can reuse over and over again. This provides a one-time investment for the contractor as well as compared to wooden formwork that can be used once and has to be disposed of after usage.                     Stiffener Riser form boards Cleats Side forms Rebar Front section Bottom plate Top plate Treads and risers are laid out on the side form. While the top and bottom plates and stiffeners are nailed through the side forms. Side forms are then fastened to the top of the joists. After the rebar has been placed, cleats and riser form boards are fastened to the side forms. Lastly, the front section is nailed into place.  
    • Types of staircase Stair Plans Both of the sites are having the same type of staircase, which is concrete stairs . A concrete stair is designed as an inclined slab with steps formed on its upper surface. Hence, it often requires careful analysis of load, span and support 1. De’bunga Uses quarter-turn stair .

Bi-Fold Door A system of hinged doors that stack against a wall Gliding Door A door with two or four panels that slide past one another Saloon Door A pair of lightweight swing doors often found in public bars Types of Mechanism   Open Open Open Open Close Close Close Close Folding Door Hinged Door The doors are hinged along one side to allow door The door operated by fitting the pivots of one door into the top and bottom pivot brackets. to pivot away from the doorway in one direction but not in the other. The axis of rotation is usually vertical. Sliding Door Pivot door slides allow the door to pivot open then slide back into the sides of the cabinet. Rotating Door The door typically consists of three or four doors that hang on a central shaft and rotate around a vertical axis within a cylindrical enclosure. It is either be mounted at the central pivot or attached to the door wings.
    • 5.7 WINDOWS Types of Windows Picture Window Picture window is a large fixed window in a wall, generally without glazing bars, or glazed with only minimum reflection of glazing bars near the edge of the window. Picture window provides an unblocked vie, as if framing a picture on the wall. Single-hung Window Single-hung window has two sashes but typically the top sash is fixed and only the bottom sash slides. The advantage of sash window that it provides cooling effect of interiors during warm weather. By opening both top and bottom of a sash window by equal amounts allows warm air at the top of the room to escape, thus drawing cool air from the outside into the room through the bottom opening. Fixed Window A fixed window cannot be opened. Its function is limited to allow light to enter. This type of window is used in where only light or vision is needed and there is no ventilation is possible because the use of trickle vents or over glass vents is absent in this type of window. Single Casement Window Casement windows are hinged on the either side and open outward to the right or left. It is usually taller than wide, their entire sash opens to provide top-to-bottom light and ventilation.
    • Installation of Casement Window The window opening is spanned externally by a brick-on-edge arch backed by a reinforced concrete lintel. As the flat arch has little strength it is supported by a mild steel angle, with ends built into the brickwork. The exposed edge painted for protection. The window frame may be fixed to the sides of brick jambs.The jamb may be fixed to the brickwork by screwing or nailing to hardwood plugs let into mortar joints. The hardwood sill helps to improve its weathering qualities, which overhangs the face of the brickwork. Where the window is set well back from the outer wall face, it is necessary to incorporate a precast concrete sub sill. Mullions should be through tenoned into heads and sills, an the transoms stubtenoned into jambs and mullions. Opening casements are held in a closed position by casement fasteners, while both casement and ventlights can be fixed in a number of open positions by means of casement stays, which may be either the peg or sliding varieties.
    • 6.0 ROOF Cross Gable From the site at De’bunga, the roof constructed is cross gable. Fly rafter Either of the end rafters in the part of a gable root that projects beyond the gable wall. Lookout A short bracket for supporting the overhang of roof. Valley Rafter A rafter connecting the ridge to the wall plate along a valley. Valley Jack A jack rafter extending from a valley rafter to a ridge. Cripple Jack A rafter joining a hip to a valley. Hip Rafter A rafter forming the junction of the sloping sides of a hip roof.
    • 7.0 Summary SUMMARY: Throughout the whole of this project, we manage to obtain more knowledge and guidance of Malaysian building construction methods compared to that of lecturers and in-class learning. Besides that, we have learned that throughout the process of building construction, compromises are made and the plans produced by architects are not finalized and it’s a process of evolutions that occurs from the beginning to the end of the project. In the first site, De’Bunga Residence, we were able to witness a three-storey bungalow at its pre-roofing stage such that most of its structural components were already completed. We learned the different names of materials in which the contractors used such as splash dash, beam starter bars, wire mesh and key holes in the mortar walls for the door frame. All of which are rather new terms we have not learned in class. This help broaden our “architectural vocabulary” as some of these terms are not written in the books and vary from country to country. At the same time, we were able to improve our observation skills. During our second site at Altitude 236, we were fortunate enough to be able to visit a condominium in which we managed to experience a totally different variety of construction methods such as using reinforced concrete to construct everything from walls to roofs and floors. The machinery used in high-rise construction is very different as well such that they have to transport building materials from ground level all the way up to the construction area. Lastly, we as a team would like to thank the people in which has given us guidance and took time to patiently explain the different components of the construction site. We would also like to thank IJM the developer for allowing us to visit their construction site and for providing us with the information we need to complete our assignment.
