- Ground floor and second storey SIREWALL suites extend on either side of a winding outdoor central courtyard, which runs the length of this long and somewhat narrow property.
- The colour and texture of the walls closely resembles the local sandstone.
- Barrel vaulted ceilings are constructed atop many of this structure’s load-bearing walls. On top of these ceilings, insulation as been incorporated which articulates with the insulation in the SIREWALLs, completing the thermal envelope. When temperatures approach 50°C, it is vital to have enough insulation to reduce the negative comfort and economic impacts of too much air conditioning.
- Repetitive design elements allowed the fabrication of modular torsion box formwork, that was used over and over again.
- Plywood torsion box formwork in panels up to 400 sqft were stripped and placed with a crane.
- Plywood had a polypropylene surface that could be welded to eliminate seams (not entirely successful)
- The thickness of the insulated SIREWALLs was reduced to the absolute minimum of 17”.
- Construction took place at temperatures ranging from 5°C to 49°C. The SBA needed protection from the heat.
- Monsoons made it imperative to protect materials and understand when work needed to be halted.
- Mixing was acheived with a high tech volumetric mixer to ensure consistent quality, and delivery was by means of a low tech ‘bucket brigade’ (40+ people) transportation of bowls (teslas) containing the soil mix, from the mixer to the top of the SIREWALL formwork.
- An onsite lab was provided to ensure consistency of soil be supplied.
- Steel reinforcing was our standard 24” grid of 15M in each wythe.
