What we do
Engineering solutions for developers, surveyors, architects, planners, and councils across the North Island.
Council needs you to manage stormwater from your development. We design the detention tanks, ponds, or swales to get your consent approved.

A few examples of how we solved real problems for our clients.
Problem: A culvert design was quoted at $700,000.
Solution: We redesigned it using a dual pipe system for $100,000.
Outcome: Same capacity, $600,000 saved. Full subdivision now complete.
Problem: Developer needed to prove building sites were safe from flooding.
Solution: We modelled the river and set conservative floor levels.
Outcome: Cyclone Gabrielle flooded the area in 2023. The assessed lots stayed dry.
Problem: A wetland classification threatened to block the entire development.
Solution: We used historical aerial photos from 1942 to prove it was never a wetland.
Outcome: Classification overturned, consent granted, 41 lots delivered.
