RESIDENTIAL SERVICES.
We support homeowners, architects and residential builders across Perth and WA with structural documentation that’s practical, efficient and easy to follow. Whether it’s a single-storey home, two-storey build, extension, or grouped development, our team provides clear advice from concept through to construction. We work closely with designers to ensure drawings align with the architectural intent, while also being cost-effective, code-compliant and builder-friendly. With decades of experience in WA’s residential sector, we understand the timelines, challenges and on-site realities that matter most.

COMMERCIAL and Government.
Our team has delivered engineering solutions for a wide range of commercial and public-use projects , from apartment buildings, childcare centres and warehouses to council infrastructure, sports pavilions and facilities. We know how to balance performance and constructability with compliance and cost. All documentation is prepared with clarity in mind, helping developers, builders and project managers move efficiently from tender to approval and beyond. Whether working with a local council or a private developer, our focus remains the same: clear communication, timely delivery and structural outcomes that last.

SITE INVESTIGATIONS AND REPORTING.
We provide detailed, site-specific reports across both residential, commercial and government properties. Our services include pre-purchase structural inspections, slab and footing reviews, dilapidation reports, construction compliance checks, and retrospective approvals. Every report is tailored to the exact requirements of your build, site or issue. We pride ourselves on fast turnarounds, practical recommendations, and clear documentation that clients and contractors can rely on at every stage of the project.
