Your submitted information

Property / project address

42 Sample Lane, Example Suburb, Auckland, 1010

What would you like to understand about this claim or variation?: I have received Claim 04 for NZ$31,800 including GST from my builder for our extension and renovation. It contains NZ$25,000 for a roof/framing stage and NZ$6,800 for a replacement stormwater pipe variation. I thought the original NZ$210,000 contract included connecting our new drainage and I have not signed an approval for this extra charge. I want to understand what the documents say, which work is included or excluded, which supporting evidence appears missing, and what questions I should ask the builder before deciding how to respond. Please explain the claim in practical building terms; I am not asking for a legal determination about payment.

Your Question / Issue

You have requested a review of Progress Claim 04 totalling NZ$31,800.00 incl. GST for your residential renovation at 42 Sample Lane, Auckland. The claim comprises NZ$25,000.00 incl. GST for Stage 04 (roof covering and associated framing works) and NZ$6,800.00 incl. GST for proposed Variation V-03 (stormwater drainage pipe replacement). You are seeking clarity on the contractual scope boundaries, the requirement for written variation sign-off, the necessary supporting documentation, and the completion status of the milestone stage.

Build Advice — what we found and what it means

Based on the documentation supplied, our assessment covers two distinct items within Progress Claim 04: proposed Variation V-03 for stormwater drainage replacement, and the milestone claim for Stage 04 roof and framing works.

Recommended Next Steps

Request written confirmation from the contractor clarifying whether the 18 metres of stormwater drainage pipe has physically been excavated and installed, or if the claim is based entirely on estimate ES-03 and supplier quote SQ-18 before work took place.
Request solid diagnostic and photographic proof of the drainage defect, including CCTV footage or logs showing the crushed or blocked pipe, photographs before removal, and as-built photos of the replacement installation.
