Why You May Need an As-Built Plan
New builds, renovations, or room extensions
Council building consent (BC) or Code Compliance (CCC) requirements
LIM documentation when selling a property
Verifying drainage work installed by contractors
Planning future upgrades, repairs, or landscaping
Locating drains before excavation or driveway installation
Undocumented or older drainage systems in areas like Napier South, Onekawa, Marewa, Taradale, Flaxmere, Akina, and Havelock North often require accurate as-builts to avoid costly surprises.
How We Create Your As-Built (4-Step Proven Process)
We inspect visible drainage components, boundary connections, vents, gully traps, and access points to establish the system layout.
Our high-resolution CCTV camera and sonde locator trace underground pipe paths, junctions, depths, and materials — giving us precise mapping, even on older or complex systems.
Your drainage network is drawn in standard council format, including pipe sizes, invert levels, distances, directional flow, materials, and any system changes or upgrades.
We supply clear, digitally produced copies ready for council submission, your builder, architect, or long-term property records.
