What this service covers
A&A work is rarely about the structure alone. It is about hacking, forming and pouring next to tenants, neighbours and live services without shutting the building down — and satisfying the Qualified Person and BCA along the way.
We plan A&A projects backwards from the constraints: permitted working hours, noise and dust control, access and hoisting routes, temporary propping, and the sequencing of structural alterations. The programme is then built around what the building can actually tolerate.
Whether the trigger is a change of use, a lease requirement or added floor area, we handle the submissions and the physical works as one package.
Typical scope of works
- Extensions, new floor area and roof works
- Structural hacking, propping and reinstatement
- Façade and external wall upgrades
- Internal reconfiguration and partitioning
- Wet works, waterproofing and floor screeding
- QP coordination and permit applications
Best suited for
- Occupied commercial and industrial buildings
- Landed homes undergoing reconfiguration
- Change-of-use and lease-driven upgrades
