How can we help?
Find answers to the most pressing questions regarding high-stakes construction estimating in the New Zealand market.
The estimate should state its region, pricing date and rate sources. Share your current supplier or subcontractor quotes so the agreed pricing basis can be used. Allowances and items awaiting confirmation are identified for review.
An estimate measures and prices the agreed drawing scope. It does not replace design certification, engineering advice or building consent. Your designer and relevant authorities remain responsible for compliance decisions.
Clear quantities, trade boundaries and recorded assumptions help your team compare quotations and review its tender. We support that process; pricing decisions and the tender outcome remain with your team.
Use the quote form for PDF, JPG or PNG plans, and include only the information needed to assess your enquiry. Ask the team about any confidentiality requirements before sharing sensitive documents. See our privacy policy for how website enquiries are handled.
Send the current drawing set, required scope and tender deadline. We will confirm the delivery programme with your quote after reviewing the size and complexity of the work.
Yes. Contact the team with the relevant drawing reference or schedule item. Clarifications, revisions and any additional work can then be agreed against the original scope.
Include the alternatives in your brief. Separate quantities and clearly stated rate assumptions can help compare the agreed options without mixing the base scope and proposed changes.
Send the revised files with their revision numbers and a description of the changes. The team can review the affected scope and confirm any change to the fee or delivery date.
Fees depend on the drawing set, trade coverage, required deliverables and deadline. Submit your plans for a project-specific quote before authorising the work.
Yes. Identify the package boundaries, available drawings and tender requirements. The team will confirm the agreed deliverables, fee and exclusions in the proposal.
Agree the stages, deliverables and invoice schedule with the team before starting. Include your purchase-order or invoice reference requirements in the project brief.
Payment terms are set out with your project quote. Review the proposal and ask the team to clarify any deposit, milestone or revision charges before accepting.
The quote form accepts PDF, JPG and PNG: up to three files, 5 MB per file and 10 MB combined. For native drawing files or larger sets, contact the team to agree a suitable transfer method.
Tell us your preferred spreadsheet layout, trade codes and import requirements. The team can confirm a compatible deliverable before work begins. Direct integrations should be agreed separately.
No. Ask AI explains construction and estimating topics, but has no live supplier prices or access to your uploaded plans. For a project quote, use the Get a Quote form and confirm the required pricing basis with the team.
No. Quote attachments are sent with your enquiry to the business mailbox. Ask AI sends the question and recent chat context to its AI provider, so avoid entering confidential project details in the chat.
