SITE CLEARANCE Site clearance is the compulsory procedure to remove any obstructing elements such as vegetation found on site to prepare for excavation or structure building. It involves: - demolition and removal of existing buildings and structures; - grubbing out of bushes and trees; - removal of topsoil to reduce levels
2. The bulldozer is then used to remove the cleared vegetation from the site. Uprooted trunks and loose rocks are pushed toward a collection point. Taller/heavier trunks that cannot be pushed by the bulldozer are towed away by another machinery.
3. Next, the topsoil at 30 cm is removed because it contains decaying organic matter and roots. This part of the soil is unstable as a construction material for foundation and structure building. Site before clearance
Site after clearance progress
surface soil is usually from 5 to 30 cm deep
STEPS soil surface
1. First, Vegetation is removed. A bulldozer is used to uproot the trees. 4. Lastly, excavate the desired depth and transport the topsoil to another space as it can be reused later. remove the surface soil
11
SETTING OUT Setting out of a building refers to the act of measuring and marking out a full size plan of the building or element of the building on site. It is usually undertaken once the site has been cleared out of any debris or obstructions and any reduced level excavation work is finished.

1. The first task in setting out the building is to establish a baseline to which all the setting out can be related.
width of foundation
2. After the baseline has been set out, each corner should be marked with a corner post. A check should now be made of the setting out lines for right-angles and correct lengths
Setting out done on site
3. After completing and checking the setting out of the main building lines, profile boards are setup to determine the corners of the buildings. These are set up clear of the foundation trench positions to locate the trench, foundations and walls.

EARTHWORK & EXCAVATIONS Earthwork is a process which involves removing, moving and adding large quantities of soil, rocks from an existing land to another area.This is done to achieve a suitable level or height for a construction purpose. The specific type of earthwork done is determined by the condition of the site and soil and to prepare the site for other construction works such as making roadways, works on bridges and under tunnels.
TYPES OF EXCAVATION Topsoil Excavation The removal of topsoil as a Building Regulation Requirement Depth varies from site to site but usually in a 150 to 300mm range. Topsoil contains flora and fauna life and decaying matter which makes the soil compressible and unsuitable to support the building structures.
Cut & Fill Method Used for sites with slopes - existing slopes are measured and levelled. This is a common and most used method as it can help save on the labour work of landfilling and also time consumed on transport. The quantity of soil that has been removed will equal to the quantity to be filled.

FOUNDATION FOUNDATION TYPE & CONSTUCTION PROCESS (SITE/REFERENCES) THE FUNCTION OF ANY FOUNDATION IS TO SAFELY SUSTAIN AND TRANSMIT TO THE GROUND ON WHICH IT RESTS THE COMBINED DEAD, IMPOSED AND WIND LOADS IN SUCH A MANNER AS NOT TO CAUSE ANY SETTLEMENT OR OTHER MOVEMENT WHICH WOULD IMPAIR THE STABILITY OR CAUSE DAMAGE TO ANY PART OF THE BUILDING
0323398 DARREN TAN YONG TEE
FACTORS DETERMINING TYPE OF FOUNDATION Foundation can be classified into shallow and deep foundation and is determined by the following factors:
GROUND CONDITION The ground or soil condition is necessary for determining the type of suitable foundation. The soil on which the building rests may be stable, level and of uniform composition, but in some situations it may be otherwise. When the load is transferred from the structure to soil through foundations, the soil tends to consolidate and settlement of foundation occurs.The settlement of foundation causes cracks in building walls, beams, slabs etc. and building can even fail in case of large settlement. Where soil close to the surface is capable of supporting structure loads, shallow foundations can be provided. Where the ground close to surface is not capable of supporting structural loads, deep foundations are used.
LOAD FROM BUILDING The loading condition depends on the form and type of building to be constructed. In case of low rise building with large span, the extent of loading is relatively modest, so shallow foundation is preferred in this case. On the other hand, high-rise building with short span has high loads. Therefore, deep foundation is required in such cases.
15
SHALLOW FOUNDATION RAFT FOOTING -
-
PAD FOOTING
Used to spread the load of the superstructure over a large base to reduce the load per unit area being imposed on the ground. Useful where low bearing capacity soils are encountered and where individual column loads are heavy.
-
Suitable for most subsoils except loose sands, loose gravels and filled areas. Usually constructed of reinforced concrete and where possible are square in plan.
square footing
STRIP FOOTING -
rectangular footing
circular footing
CANTILEVER FOUNDATION
Suitable for most subsoils and light structural loadings such as those encountered in low to medium rise domestic dwellings where mass concrete can be used.
-
Can be used where it is necessary to avoid imposing any pressure on an adjacent foundation underground service.

16
DEEP FOUNDATION Pile Foundations -
A series of columns constructed or inserted into the ground to transmit the load(s) of a structure to a lower level of subsoil. Can be used when suitable foundation conditions are not present at or near ground level making the use of deep traditional foundations uneconomic.
Classification of Piles Piles may be classified as either End bearing or Friction piles, according to the manner in which the pile loads are resisted.
End Bearing Piles
Friction or Floating Piles
The shafts of the piles act as columns carrying the loads through the overlaying weak subsoils to firm strata into which the pile toe has penetrated.
Friction piles obtain support by adhesion or friction action of the soil around the perimeter of the pile shaft.

17
ON SITE: REINFORCED CONCRETE (RC) FOOTING Pad footings are made up of rectangular or square concrete ‘pads’ that support localised single-point loads such as structural columns, groups of columns or framed structures.
CONSTRUCTION PROCESS
Pad footing on-site Excavation is done to the desired level. A layer of lean concrete is placed to provide a firm base.
Formwork is built. Spacer blocks are placed before reinforcements are laid.
Formwork
Reinforcement bars bent and tied in a basket
Stump reinforcements are erected in rectangular arrangement. Ready-made concrete will set and cure in the formwork and is dismantled afterwards
The rebar “basket” is placed into the formwork, raised above the concrete base.
18
SUPERSTRUCTURE BEAM & COLUMN BEAMS AND COLUMNS ARE USED TO AS A STRUCTURE OF A WHOLE BUILDING . THE USAGE OF THESE STRUCTURAL ELEMENTS ACTS AS A SUPPORT THAT CAN WITHSTAND LOAD PRIMARILY BY RESISTING BENDING . THE PRECAST CONCRETE ARE REINFORCED AND CAN BE APPLIED TO ANY BUILDING ONCE THE BEAMS AND COLUMNS ARE DONE. BEAMS ARE USED AS A LEDGE FOR OTHER PRECAST FLOORING TO REST ON. THEY ARE ALSO MANUFACTURED TO SUIT EACH PARTICULAR STYLE OF BUILDING DESIGNS.

.1
BEAM Materials used on our site: Reinforced Concrete (RC) - Also known as composite beam, it is made of concrete and steel. - RC is a composite material in which the poor tensile strength and ductility of concrete are counteracted by including reinforcement.
-
Here the reinforcement is steel reinforcing bars (rebar), embedded passively in concrete before the concrete sets.
-
A singly reinforced beam is used, in which the concrete element is only reinforced near the tensile face and the reinforcement, called tension steel.
-
This strengthens concrete beams, columns, and slabs by providing more resistance towards compression and tension forces.
20
Importance of reinforcement -
Without reinforcement, beams will crack if too much pressure is applied to it
-
Reinforced concrete can fail due to inadequate strength, leading to mechanical failure, or due to a reduction in its durability. Corrosion and freeze/thaw cycles may damage poorly designed or constructed reinforced concrete. When rebar corrodes, the oxidation products (rust) expand and tends to flake, cracking the concrete and unbonding the rebar from the concrete.
21
DEFLECTOR BEAM DETAIL Beam-to-Column connection : Beams are set on bearing pads on the column Corbels. Steel angles are welded to metal plates cast into the beams and columns and the joint is grouted solid.
22
PROCESS OF IN-SITU CASTED BEAMS
1. Construction of a beam will require formwork for its sides and soffit. The latter will have to be supported temporarily until the completed beam has gained sufficient strength. 2. Once soffit formwork has been erected, the necessary reinforcing steel is fixed, making the necessary connection to the reinforcement in the supporting columns or other elements. The side formwork is then fixed. Spacers are required to make sure that there is adequate cover to the reinforcement. 3. The concrete is then cast and the top surface of the beam finished off to the required level. After finishing, the top surface must be covered to prevent moisture loss. Generally the side formwork may be removed the day after the concrete is cast, taking care not to damage the surface of the concrete and corners. All exposed surfaces must be covered with polythene or wet hessian to prevent moisture loss for about 5 days, so that the concrete is fully cured.
4. As indicated above, the soffit supports and the soffit formwork should not be removed until the beam had reached sufficient strength for it to carry its own weight and any additional imposed loads.
23
COLUMNS 1. Columns at ground level are constructed on a pile cap, edge beam or some other type of foundation. 2. On our site the construction process is similar. At the base of the column, ‘starter’ bars will project from the supporting member. 3. Reinforcement, main vertical bars and horizontal links, will lap with starter bars for continuity. Reinforcement projects from top of the column for continuity. Formwork is fixed, with the necessary props to make sure that it is vertical and does not move during the casting of the concrete. 4. A variety of methods are used to fix the base of the formwork in place and to ensure a grouttight seal. Then, concrete is placed slowly and vibrated (using poker vibrators). 5. The side formwork is thus removed the day after the concrete is cast, taking care not to damage the surface of the concrete, corners etc. 6. Finally it may be appropriate to provide temporary protection to corners to prevent damage by other construction work. 7. To conclude, the column should be wrapped with polythene for about 5 days, to prevent moisture loss so that the concrete is fully cured.

SUPERSTRUCTURE SLAB REINFORCED CONCRETE SLABS ARE USED IN FLOORS , ROOTS AND WALLS OF BUILDING AND AS THE DECK OF BRIDGE . SLABS MAY SPAN IN ONE DIRECTION OR IN TWO DIRECTIONS AND THEY MAY BE SUPPORTED ON MONOLITHIC CONCRETE BEAMS ,STEEL BEAMS, WALLS OR DIRECTLY TO THE STRUCTURE ‘S COLUMNS
0327850 NAHIDA AUCKBARAULLEE

SLABS -
-
-
-
Here the slabs are made of reinforced concrete. They are plate structures, horizontal slabs of steel reinforced concrete, laid with reinforcement bars to withstand load. They are supported on foundations and is used to construct the ground floor of the building. Ground-bearing slabs built using formwork.
26
GROUND SLABS
Concrete Slab -
-
-
Minimum thickness is 100mm and maximum is 500mm, depending on the load it has to bear. Directly on the ground , can drain heat from a room. Concrete slabs are usually cast above a layer of insulation such as expanded polystyrene, and the slab may contain underfloor heating pipes. However, there are still uses for an uninsulated slab, typically in outbuildings which are not heated or cooled to room temperature. In those cases, casting the slab directly onto a rocky substrate will maintain the slab at or near the temperature of the substrate throughout the year, and can prevent both freezing and overheating.
Construction -
-
-
In site concrete slabs are built on the building site using formwork - a type of boxing into which the wet concrete is poured. If the slab is to be reinforced, the rebars are positioned within the formwork before the concrete is poured in. Plastic tipped metal, or plastic bar chairs are used to hold the rebar away from the bottom and sides of the formwork, so that when the concrete sets it completely envelops the reinforcement. Ground slab, the formwork may consist only of sidewalls pushed into the ground. The formwork is commonly built from wooden planks and boards, plastic, or steel.

Precast Concrete Wall Construction Process 1. Remove precast wall from delivery truck 2. Conduct sample measurement to confirm on the accuracy of the critical dimensions of precast concrete elements and openings 3. Check the locations and conditions of the lifting inserts before hoisting 4. Check on the accessibility of unloading point and storage area 5. Set references line and offset line to determine the position of the precast elements to be installed 6. Provide level pads (or shim plates) for setting the level of the elements. Set the level pads in the position using non-shrink mortar 7. Lift and rig the panels to its designated location with the use of wire ropes 8. Adjust the panel to the position and secure it with diagonal props 9. Prepare and apply non-shrink mortal to seal the gaps along the bottom edge of the inner side of the panel 10. For corrugated pipe sleeve or splice sleeve connection, prepare and pour non-shrink grout or proprietary grout 11. For panels with cast in-situ joints ,install the joints rebars as required 12. Remove excess grout infill after precast wall is erected

35
PLASTERING TECHNIQUE
Plastering Process of covering rough surfaces with a plastic material to obtain an even , smooth,clean and durable surface -a mixture of lime or gypsum ,sand and water ,sometimes even with fiber added will be used for coating walls and when harden Splash dash help to increase friction when applying plaster to the wall and increase the bonding
Types of Plastering 1. lime plaster - binding agent is lime 2. cement plaster - binding agent is cement 3. mud plaster - applied in two coats, thickness for first and second coats is 18mm and 6mm respectively 4. stucco plaster - decorative type of plaster 5. plaster on lath - lathing might be expanded metal or timber 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
36
Process of Plastering After the brick wall is completed, plaster has to be applied on wall before painting. 1. Use a mixer to combine all of the ingredients that is to make plaster. 2. Put a corner of the hawk into the plaster mix and use the trowel to push the mix onto the hawk. Rest the trowel on the hawk, tilt the hawk back and scrape the plaster onto the trowel. 3. Evenly spread the mortar across the wall when applying it. Continue applying the plaster until you’ve covered all of the wall. 4. Once the plaster is touch dry, screed the wall. Do this by dragging the straight edge along the wall. Screeding takes any excess plaster off the wall to give it a nice flat finish. 5. After the last screed, there might be areas where the plaster is uneven or patchy. Use the trowel and hawk to apply plaster where it’s needed.
Mixer -Plastering should be done after curing on the brick wall. -Cement and fine aggregate mix ratio should be: // 1:6 (1 cement : 6 fine aggregate) for internal plastering of bricks and // 1:4 for external plastering -Never do a plastering beyond 12 or 15mm thickness on a brick wall

STEEL TRUSS SYSTEM
Our site building has a steel truss roof system. A steel truss system is the Queen Post Truss is designed to be a very reliable, simple and versatile type of roof truss that you can use at any given time. It offers a good span, around 10m, and it has a simple design which makes it perfect for a wide range of establishments.
51
FORCES The truss roof has two different forces that act on it. One is Tensile force (this is a pulling away from each other force) and the other is compressive force (this is a push towards each other force). The tensile force is on the base of the roof and the diagonal steel truss while the Compressive force work on the top part of the roof and the steel truss perpendicular. Therefore the force cancel each out making the roof stable and suitable for the structure.
Tensile force Compression force

4. UNDERLAYMENT The usage of sisalation under the roof frames is as follows: Super Sisalation (A) Physical characteristics: The outer layer of aluminium foil is bonded to high density kraft papers which is then bonded together with heavy flame retardant and tear strength. (A) Thermal performance: When used in conjunction with an airspace. Sisalation is an effective thermal insulation material because of the high reflectivity, and low emissivity of its aluminium foil surfaces.

5. ROOF COVERING Cement Mortar Is a materials which gives a protective surface to the roofing structure. The function is only to prevent ingress or egress of heat & moisture into the building. The material used is tiles which are made of a ceramic material and is hard and brittle, but The disadvantage is that it is poorly suited for places where tree limbs can fall on a house's roof. As your site does not that any large tree is a good suitable material.

6. ROOF FLASHING The flash is to drain water away from the roof so that water leak into the structure from an angle or joints. Thin pieces of impervious material installed to prevent the passage of water into a structure from a joint or as part of a weather resistant barrier (WRB) system. In modern buildings, flashing is intended to decrease water penetration at
objects such as chimneys, vent pipes, walls, windows and door openings to make buildings more durable and to reduce indoor mold problems..

7. ROOF DRAINAGE GUTTER A gutter is a component of water discharge system for a building is. Water collected by a rain gutter is fed, usually via a
downpipe (also called a leader or conductor),from the roof edge to the base of the building where it is either discharged or collected.

As conclusion, surveying a process along the project running enhance the quality and the precision of building construction. Also it helps to identify certain material used that actually essential for building also give a suitable ambience to the user of the space.
Excavation process was brought to clear the land
Piling is implanted as a base and foundation
Scaffolding is built to hold the formwork for the first floor beam
Formwork of ground beam is being filled
Construction of roof, doors, windows and walls marks end of the project
Backfilling of sand is carried on after the completion of the ground beam
Construction of ground floor slab formwork
First floor slab is constructed after the completion of first floor slab

Through this project, we were able to introduce basic principles and procedures of construction process through real-life project. We were also able to understand the sequence and coordination of construction at site. Furthermore, we were able to demonstrate our understanding and knowledge of construction, material and technology.
In the end, we have successfully produced a complete documentation and an analysis of construction elements. We also understood and had an explanation of construction elements and its components. We had a lot of fun going into this project and learned a lot from the contractors that brought us along and also gained a lot of experience.
