Frequently Asked Questions (FAQs)

1. Do you follow NZ-specific formats in your estimates?

Yes, we use NZS4202 formatting when requested. All takeoffs and BOQs are structured to match how local builders, councils, and suppliers expect to receive them.

2. Can you estimate for residential and light commercial projects?

Absolutely. We work with builders, subcontractors, material suppliers and QS teams across both residential and light commercial scopes in Auckland.

3. What do I need to send to get a QS quote?

Just your architectural plans and any supporting documents. You can upload them via Dropbox or Google Drive, or email us directly.

4. How fast can I get my takeoff or BOQ?

Most estimates are delivered in 3–5 working days. If we need more time based on scope, we’ll confirm that up front.

5. Do you include pricing in the reports?

Yes, we can include material and labour pricing if needed. Just let us know your preference when you request the estimate.

6. Can I request changes after receiving the report?

Yes, we support plan revisions or scope changes. Just send us the updated drawing and we’ll revise your report accordingly.
