• Retail and commercial centres,
• Basements

Our expertise covers:

• Scoping, management and delivery of field and laboratory investigations,
• Derivation of geological and subsurface models,
• Seismic appraisals – liquefaction susceptibility and effects analysis, subsoil class assessment and derivation of seismic design criteria,
• Analysis of groundwater regimes and groundwater drawdown effects;
• Design of shallow and deep foundations,
• Settlement assessments,
• Design and detailing of retaining walls and in-ground, palisade walls,
• Slope stabilisation solutions,
• Ground improvements,
• Floor slab and pavement assessments,
• Construction observation, testing and certification.

Infrastructure

We have a proven track record of delivering on diverse infrastructure projects – including the Orams Marine redevelopment, George Bolt Memorial Drive Realignment, Opotiki Marina, and Auckland Airport’s second runway. We’ve also worked on a range of port and wharf re-development projects, design and detailing of significant retention structures and large-scale ground improvements on settlement prone and liquefaction susceptible ground.

Our team can provide advice and geotechnical solutions covering both permanent and temporary works design for:

• Roads and rail,
• Ports and wharves,
• Retaining walls,
• Bridges,
• Heavy duty pavements (e.g. runways),
• In-ground storage tanks and pump stations,
• Wastewater and stormwater tunnels,
• Buried services,
• Ground improvements.

Our infrastructure expertise includes:

• Scoping, management and delivery of field and laboratory investigations,
• Derivation of geological and subsurface models,
• Seismic appraisals – liquefaction susceptibility and effects analysis, subsoil class assessment and derivation of seismic design criteria,
• Analysis of groundwater regimes and groundwater drawdown effects,
• Design of shallow and deep foundations,
• Settlement assessments,
• Design and detailing of retaining walls,
• Slope stabilisation solutions,
• Ground improvements,
• Construction observation, testing and certification.
