Timeline depends on project complexity. Simple wall removals in residential homes typically take 2-4 weeks including engineering approvals. Major commercial projects or those requiring temporary propping may take 6-12 weeks. We provide detailed project schedules during the engineering and planning phase before construction begins.

Yes, all structural alterations require Development Application (DA) and Construction Certificate (CC) from your local council. We coordinate all approvals with certified structural engineers and handle documentation requirements. Building Commissioner certification is provided on completion of all work.

Engineering approvals typically take 1-2 weeks for standard projects and 4-8 weeks for complex multi-story alterations. We manage all coordination with structural engineers and councils to minimize delays. Our detailed preliminary engineering reports help accelerate council review and approval processes.

Costs vary significantly based on scope. Residential wall removals typically range $8,000-15,000 including temporary propping and structural frame installation. Commercial projects with complex engineering and phasing can cost $50,000-200,000+. We provide detailed quotes after structural assessment and engineering review.

This depends on the project scope and council requirements. Small residential alterations may allow occupancy with noise and dust management. Large commercial or multi-story work typically requires partial or full building evacuation during the alteration phase for safety compliance. We work with your occupants to minimize disruption.

We use engineered temporary support systems including acrow props, steel needling beams, and hydraulic jacking systems designed by structural engineers for each specific project. All temporary works comply with building codes and are monitored daily for performance and safety throughout the alteration process.
