We provide much more than pipes in the ground

We know Council standards inside out, having even helped shape them. Our extensive experience forms the backbone of our approach, focusing on strong engineering solutions that respect nature.

We're all about clear communication and meeting deadlines. If we can't fit your schedule, we'll tell you upfront – no fluff.

Focus Areas

Our services & areas of expertise

Structure Planning

Detailed structure plan analysis and reporting for local government, including zoning, roading, 3 waters and ecology.

Water Supply Engineering

Modelling, design, scheme and pressure management and optimisation for municipal water supply entities.

Waste Water Engineering

Modelling and design of urban waste water networks and pump stations.

Stormwater Engineering

Modelling and design of private and public stormwater devices and networks. Modelling and analysis of stormwater catchments, and hydraulic and hydrologic analysis.

Roading

Road design for urban, rural and state highway.

3D Infrastructure Modelling

We employ cutting-edge tech to craft 3D models, enabling councils, developers, and iwi to visualize upcoming projects. Our output: an HTML-based 3D model accessible from any PC, fostering seamless online viewing.

Structure Planning

Our Structure Planning service evaluates the potential for transitioning extensive land zones from rural to commercial, industrial and residential. This comprehensive report guides councils, landowners, and developers by addressing infrastructure enhancements such as roading, sewer, stormwater, and water systems. We analyse infrastructure upgrades and advise on crucial elements like street design, stormwater ponds, and reserve land positioning. This instrumental tool informs Councils and Land Developers, and streamlines subdivision processes.

Roading

We develop roading networks for structure planning and provide geometric road design for private developers, local government and Waka Kotahi. Using cutting edge design and visualisation software, we design roads to work in harmony with the environment and to comply with Waka Kotahi, Austroads, and Local Authority Standards.

Water Supply Engineering

Utilising digital models, we design and develop water supply systems for municipalities and local government entities, from new schemes to network modifications, pressure zoning, and leakage reduction.

Stormwater Engineering

We carry out engineering infrastructure assessments and design for local government asset management.

We also design stormwater infrastructure for subdivisions, working closely with Iwi, and local government agencies. Out team assists with all aspects of the consent process to ensure compliance with the Te Mana o te Wai frameworks, NZ Standards, The District Plan, The Building Code, and Local Authority requirements.
