FLIPBOOK SECTION 2D: construction stages, details and annotations

Stage 01 FOUNDATION SYSTEM

Prior to site demolition, existing conditions are examined by land surveyor, site safety and site office are set on site.

The the site went under demolition using excavators. After the earth is exposed, the top soil was removed and ground was watered to ensure earth strength. Trenches are then excavated, compact sand and insulation then been set out.

1. LAND SURVEYOR Land surveyor come on site and survey on existing conditions, examine on water meter, soil condition, electric wire, storm water system, sewers etc.

2 SITE OFFICE AND SITE SAFETY Set up safety fences and warnings, emergency assembly point and safety signs around site.

First-aid box, fire extinguisher, and construction schedule prepared. Each construction worker on site must wear a full set of protective equipment: hard hats, safety vests, gloves, goggles and hard shoes.

4. STRIPPING AND WATERING Prior to excavation, use Dial Before You Dig (DBYD) to locate existing underground services, to prevent damage and disruption. Excavators are employed to remove top soil, which is soft soil containing roots, fill, grass and organic matters. This soft soil is unsuitable for load bearing . If natural ground has shrinkage cracks, water site for five days to avoid cracks.

AA A200

5. TRENCHES Trenches to be dig either using a smaller excavator or man power, to provide space for reinforce trench mesh. 700mm deep 400mm wide trench for the edge beams, and 400mm deep 300mm wide trench for the internal beams.

5 6. SAND AND INSULATION Instead of using natural soil, 50mm packing sand are used and compacted with a soil vibratory roller. Compacted sand is easier to level and is good with vertical loads. 25mm thick insulation with a R-value of 1.2 is installed to perimeter of slab.

3. DEMOLITION Excavators with loaders and bulldozers are employed to demolish existing rainwater tank and slabs, extent of existing house be demolished according to architectural drawing A160, and refer to AS 2601 The Demolition of structures.

Stage 02 FLOOR SYSTEM Edge beams, internal beams and ground floor slab are constructed all at once. Prepare pipes setout, membranes and steel reinforcement prior to concrete pour. Concrete is tested first to ensure best performance, concrete comes out from concrete truck then poured, compacted, flattened using different machineries. Then the concrete slab going under curing process for 14 days, concrete went from plastic phase to setting to hardening.

1. MEMBRANE 0.9mm damp proof membrane installed between structural slab and under slab insulation, acting as a moisture barrier so moisture will not transfer between soil and concrete.

3. STEEL REINFORCEMENT 4-12-TM (4 bars of trench mesh 12 in diameter) are placed for both edge beam and internal beams. Steel trench mesh are place at the lower part of the footings to improve the tension force of the footings. Steel mesh reinforcement are placed and secured with plastic bar chairs.

Stage 03 STRUCTURAL SYSTEM (BUILDING FRAME GROUND FLOOR)

2. TIMBER STUD WALL(AS1684,AS1720) Timber supports were used to support stud wall during erecting. Load bearing timber walls are constructed using 90 x 45mm timber studs at 450mm central spacing, by screwing them between top and bottom plates. Noggings are screwed between studs to protect studs from buckling. Plywood sheet bracing or 30x0.8mm crossed strap Hoopiron bracing were used to provide rigidity and stability.

After concrete slab, the next stage is the structural system for the ground floor. Load bearing steel columns and walls are set up first. The steel columns are bolted and welded to steel bottoms plates, load bearing timber works are constructed and braced. Recycled bricks are used for the brick veneer and double brick cavity walls later on.

1. STEEL COLUMNS (AS4100, AS3679, AS1538, AS1554.)

After removing the concrete formworks, 2/125 x 125 x 12L and 89 x 89 x6 SHS were erected and wedge anchored onto steel base plates.

Steel bearing plates are used to distribute the concentrated load imposed by the columns.

The 15mm grout raise steel above ground and avoid it from rusting. Temporary timber bracings and supports were used during erection for PARAPET safety and alignment. Clamps were used to hold RL 45.090 timber in place.

Stage 04 FLOOR SYSTEM (INTERMEDIATE SUSPENDED FLOOR)

2. FLOOR JOISTS 300 X 45 LVL floor joists at 450 central spacing are bolted on to hot dip galvanized steel beams and formed the whole intermediate suspended floor. Timber blockings were fixed perpendicular to floor joists to stiffer the joists and prevent them from buckling. Double joists were used for openings and cantilever.

The intermediate suspended floor is supported using floor joists and steel beams, load is transferred to the beams then to the ground through steel columns. Crane is used in this stage to lift up heavy steel beams, and scaffolding used to support construction workers and materials. Yellow tongue is screwed to floor joists and provide supports for workers to walk on.

4. YELLOW TONGUE SUBSTRATES 19mm Yellow tongue substrates been nailed to joists, which provided protection against humid conditions. Space fasteners at 150 spacing to perimeter edges, 300 spacing in the body of boards and all joins. Stairs opening is blocked by yellow tongue at this stage, to provide support for workers to walk on. The stair opening will be cut open at later stage.

Stage 05 STRUCTURAL SYSTEM (BUILDING FRAME FIRST FLOOR)

3. NOGGINGS Noggings staggered over a centre line for easier nailing between studs.

On top of the intermediate suspended floor, the first floor is erected fully using stud wall and double studs walls.

With studs transfer loads from top plates to bottom plates, noggings strengthening the studs, crossed strap Hoopiron bracing secure the wall and temporary timber supports the whole structural system during erection. Double sided ladder, table saw, and screw guns were the equipments used at this stage.

1. BOTTOM PLATES Bottom plates were fixed onto the intermediate suspended floor, which then holds studs in place.

2. TIMBER STUDS 90 X 45 mm timber studs were used for the building frame on the first floor, with 450mm spacing for external walls and 600 spacing for internalPARAPET walls. Double studs at the corner or next RL 45.090 to secure the area. The wall on the to openings, East side is 90mm double stud cavity wall, with a lower stud wall on the inside, providing supports for box gutter and provide space for extra insulation.

Stage 06 ROOF SYSTEMS (ROOF STRUCTURE & COVERW)

4. BOX GUTTER Marine plywood was fastened on ceiling joists between the double stud wall and box gutter was installed on top of the marine plywood, with additional flashing and capping to make sure the roof structure is water-resistant.

The roof structure was formed by ceiling joists, soldier studs and roof bracing. Waterproofing is very important in this area. Roof sheets and box gutter at a gradient are used to direct water away from the roof system. Sarking, capping and flashing are other details to prevent water from getting in. Thermal insulation is another important factor here, to insulate the roof and create a thermal bridge.

1. CEILING JOIST 200x45 LVL at 600 central spacing were used for the ceiling joists, with perpendicular blocking installed between the joists and connected by joist hangers. Soldier studs at various sizes are fastened on to every third ceiling joist. Timber battens are fastened on to soldier studs and support roof sheet.

Stage 08 WALL SYSTEMS (CLADDING) External wall claddings and finishes are installed and painted at this stage. For the ground floor, external wall was painted, and for the first floor, sarking was installed under timber batten and charred shiplap cladding then fixed onto battens. The structural system for the internal stairs are constructed and hydronic in salb heating coils are placed on insulation and covered with concrete screed.

1. SCAFFOLDING Scaffoldings were assembled on site for safety and provide a platform for installation of the exterior wall systems.

4. FINISH CLADDING 130mm Prefinished charred timber shiplap cladding installed for first floor external walls in vertical orientation, the boards were fixed on the battens with concealed stainless-steel screw fixings.

Charred timber is a traditional Japanese method which forms a carbon layer on the exterior of the timber boards which protects the timber inside and less maintenances needed.

Shiplap cladding ensure a sealed cladding with hidden fixings.

2. SARKING Breathable sarking was attached, to outer side of stud walls, the sarking allows the vapor from the heating to get outside, but at the same time protect from cold or heat from outside.
