W07 – STUDIO REPORT
153 FRANKLIN ST The plan is to build 830 apartments, with a prediction of 2000 residents. The first 330 apartments are planned to be handed over in December this year.
Large prefabricated concrete columns span 2 floors each. Each column is lowered onto rebars (re-enforcement bars). These have been placed over grout which then prevents the column from moving.
On site there are generally 450 workers from Monday to Friday, 300 on Saturday and the project is currently also being worked on Sundays as well.
BASIC STRUCTURE Each floor is based on a concrete slab cast in situ. For each floor the slab is divided into 2 sections poured separately, one day apart. The slab is also pre-tensioned with wires. This, as we have learnt in our lectures, helps to balance the concretes strength under both compressive and tensile forces.
