South Island

We have undertaken work in the South Island since 1984 and have had a permanent presence in Christchurch since 1999.  From our office in Moorhouse Avenue and an office in Auckland, our engineers and geologists are well-positioned to undertake projects throughout New Zealand. 
Water resources, geotechnical, and civil engineering services comprise core areas of expertise, and our teams work closely together to provide efficient and cost-effective solutions for our clients.

Water Resources

Our water resources group, which includes two Category A Recognised Dam Engineers, has the capability and experience to undertake investigation, design, analysis, and management for a variety of water resource projects including dams and associated structures, irrigation schemes, flood assessments, and stormwater management and mitigation.  Clients include councils and government agencies, power generation companies, land developers, farm owners, and private individuals. 

Recent projects include embankment dam strengthening for the Arnold power station; various dam regulatory reviews for building consent; dam management and civil safety inspections for Trustpower; design of a settling pond and infiltration gallery intake for a pump station on the Rakaia River; and the design of several frost-fighting reservoirs.


The in-depth knowledge of our engineers and geologists ensures we have the skills and experience to provide a solution for the wide variety of geotechnical issues relevant to South Island conditions.

Projects include design of foundations and retaining walls for land often subject to soil strength variations; investigation and reporting in support of resource and building consents for new subdivisions and retirement villages; investigations to identify earthquake damage on behalf of insurance companies; and geological investigation, stability assessment, and quarry design.


Our civil engineering team provides a range of infrastructure and land development design services including earthworks assessment; stormwater management and mitigation; pavement and roading; civil works tenders and contract preparation; and feasibility and due diligence assessments.

Recent projects include Belfast Village subdivision in Christchurch, two retirement villages in Christchurch, and Worsleys Road Stormwater outfall in the Port Hills of Christchurch.
