The Seascape tower comprises more than 12,000 tonnes of imported structural steel, including a multi-storey external mega-frame, seismic bracing systems, and integrated viscous dampers designed to control wind and movement in New Zealand’s tallest residential building.
Ensuring compliance for such a complex steel structure required specialist technical assurance aligned with AS/NZS standards, detailed design verification, and rigorous quality control across both fabrication and erection.
Operating upstreaming management of statutory checks, the work provided a full layer of technical due diligence covering shop-drawing verification, welding procedure qualifications, non-destructive testing (NDT), coating and durability requirements, and comprehensive Inspection and Test Plans (ITPs).
This disciplined, standards-based approach minimised construction risk, prevented rework, and ensured the entire 12,000-tonne steel system was fully compliant, safe, build-ready, and able to be installed smoothly and without issues.
