Fit for purpose and fit for budget design.

BTW’s engineers take projects from concept through to IFC (Issued for Construction) drawings for roads, earthworks and three waters infrastructure, with clear staging, fewer surprises and confidence in compliance.

Why choose this service:
  • Code-compliant, buildable designs that meet New Zealand standards and council requirements
  • Efficient use of materials and staging to reduce cost, time and rework
  • Integrated delivery for smooth progression

Our Chartered Professional Engineers deliver certified civil and three waters solutions across subdivision, infrastructure, and asset upgrades. Using Civil 3D and other modelling tools, our team provides clarity at every stage, from concept optioneering to preliminary and detailed design. We align closely with our in-house planners, surveyors and environmental specialists, ensuring each design supports consenting requirements and sustainability goals from the outset. This collaborative approach helps minimise risk and maintain programme certainty.

HOW WE HELP:
  • Civil Engineering Design, including optioneering of concept solutions, earthworks, and
    civil infrastructure design.
  • Water and Wastewater Design, including reticulation modelling and design, treatment solutions, storage solutions, and general infrastructure (Wai-eye Water Services)
  • Environmental Stormwater Design, including pond/wetland design, stormwater attenuation solutions, erosion and sediment control solutions, and provision of environmentally sensitive management solutions.
  • Traffic and Transportation Design, including traffic assessments, road and pavement design, and carpark/accessway design.
