• Earthquake strengthening to an engineer's design

• %NBS upgrades for earthquake prone buildings

• Strengthening work arising from a Detailed Seismic Assessment

• Structural steel framing and portal frame installation

• Concrete shear walls, core drilling and epoxy anchoring

• Foundation underpinning and new concrete footings

• Unreinforced masonry securing, parapet and chimney bracing

• Facade and veneer tie fixings

• Heritage building strengthening

• Staged programmes in occupied and tenanted buildings

• Biosecurity controlled sites and quarantine procedures

• Site establishment and temporary works

• Scaffolding and access on steep terrain

• Craneage and materials handling on constrained sites

• Piled foundations and retaining structures

• Remote and coastal building projects

• Demolition on restricted access sites

• Helicopter only access sites
