This week we went off the campus and had a site visit. First here is the foundation of a site. We can see that is in the process of making the foundation and couldnâ€™t guess the constructing of it yet.
Some materials for using.
In the second picture, we can see some concrete-reinforcing bar which was mix in the concrete to make the foundation. Inside the building, we can see composite decking that span across the joists it increase the stiffness and spanning capability. Its also the tensile reinforcement. The steel reinforcement will stay across the decking. The part that circled in yellow is the wood forming board of the concrete slab. Hence the decking is also as formwork for a site cast concrete slab. (Chin, 2008)
After listening the explain from staff in the site, we know that both of black part and white part are covered with special paint. Black part is radiation-proof and white part is waterproof.
The left picture shows the insulation filled with special material like cotton fibre. The right picture shows the auto-door which provide protection when a fire happen.
From the basement of the building, the foundation of the building can also be recognized as site cast concrete. The pipe was insert into the concrete column through the lighter part to pump the concrete in.

Week 8 Composition A. Concrete wall and ceiling of ground level. B. Brick wall C. Thermal insulation D. Timber stud E. Sealant and joint filler: helps relieve the stresses caused by thermal expansion and contraction; F. control the depth of the sealant contact with the joint part G. Cavity flashing H. Wall ties I. PFC (parallel flange channel) J. Frosted plastic sheet K. WPS(water proofing sheet)
Week 8 ① ② ③ ④ ⑤ ⑥
Building Process the framing are being built based on the main structure joints are being set the connected wall tied and cavity flashings are built the water proofing are added to the structure. the connected wall tied and cavity flashings are built. the brick walls, PFC and other details like sealant and joint filler.
Pros and cons: Efficient structure Sustainability and environmental analysis: Pre-cast concrete wall and floor requires large amount of embody energy
Week 9 Absence the tutorial. Interrogation of the detailing decisions and purpose: • Concrete wall: concrete wall only exist on the ground flood as those bearing wall carries more load than the first floor. • Insulation: thermal insulation and sound insulation • IL: short for unknown, but probably for acoustic • Timber: probably the soles plate part of the wood stud framing to position the insulation and decreasing the weight of the wall. • Weep holes: allowed moisture to get out following the flashing
• Concrete floor .
Week 10 LVT (Laminated veneer timber) :made by glued cross section timber pieces under pressures. Therefore it is a very strong and replaceable material. In formwork of the site cast concrete . This week we went to the pavilion site and learn more about construction of the building from the staff in the site. The drain inside the wall has small holes at the top that let the moisture in the wall get in. Other brick concrete wall has high dense brick that achieve selfwaterpro
Use of it: Support and connect the plywood board .
The roof system is supported by the Purlin and the steel columns. ① the timber is not strong enough to support the superstructure ② the steel can provide some reinforcements. ③ The beams continues over grinder (overhang) ④ bolt to keep beam from shifting (Ching, 2008).
