How can we help?

Find answers to the most pressing questions regarding high-stakes construction estimating in the New Zealand market.

How do you account for NZ-specific material and labour fluctuations? +
We maintain a proprietary real-time database that tracks regional material pricing (steel, concrete, timber) and labour rates across New Zealand. Our AI models analyse these fluctuations daily to ensure your budget remains accurate.
How do you ensure compliance with NZ building codes (NZS 4210)? +
Our estimating team is extensively trained in New Zealand's building code framework. We automatically validate takeoffs against NZS 4210 standards and local council regulations, ensuring fully compliant bids.
Can you help us win high-value tenders against large competitors? +
Absolutely. By combining our 98% accurate cost models with deep local market intelligence, we give you the pricing confidence and data-backed justification needed to outperform larger competitors.
Is our project data and pricing strategy kept confidential? +
Yes. We use enterprise-grade secure cloud infrastructure to store and process your information, ensuring that your competitive edge remains strictly protected.
What is your typical turnaround time for an estimate? +
For standard residential projects, our turnaround is typically 3-5 business days. For complex commercial developments, we provide a detailed timeline upfront and expedite based on your tender deadlines.
Do you offer support after the bid is submitted? +
Yes, our support doesn't end at handover. We provide post-bid support, helping you answer queries from clients and adjust estimates if scope changes occur during negotiations.
Can you provide breakdowns for alternative material options? +
Definitely. We often model multiple scenarios (e.g., standard vs. premium materials) so you can present the client with clear cost-benefit analyses and make informed decisions.
What happens if my project scope changes during the estimate? +
We adapt immediately. Simply notify your lead estimator, and we'll update the takeoffs and costs, ensuring the new scope is reflected before you finalize your tender.
What are your pricing structures for estimating services? +
We offer flexible pricing, including fixed-rate project fees, hourly rates for complex consultations, and subscription models for long-term estimating partnerships.
Do you offer fixed-fee quotes for commercial projects? +
Yes. For commercial projects with well-defined scopes, we provide a fixed-fee quote upfront, so you know exactly what the estimating cost will be with no hidden charges.
How does billing work for long-term or phased projects? +
For phased projects, we bill per stage (e.g., Foundation, Framing, Finishes). We provide detailed invoices with line-item breakdowns, ensuring total transparency.
Do you require a deposit before starting the estimation process? +
We often waive deposits for established partners. For new clients, we require a 25% deposit to initiate the takeoff process, which is fully credited towards the final bill.
Which software formats do you accept for blueprints? +
We accept all standard file formats, including PDF, DWG (AutoCAD), and RVT (Revit). Our AI engine automatically processes and digitizes these plans for takeoffs.
Do you integrate with our existing project management software? +
Yes, we integrate seamlessly with platforms like Procore, Buildertrend, and Xero. We can export our estimates directly into your existing workflows.
How does your AI engine calculate real-time material costs? +
Our AI scrapes live data from NZ supplier databases and global market indices. It cross-references this with historical project costs to predict material price fluctuations accurately.
Is the data from my past projects used to train your AI models? +
We prioritize data privacy. Your project data is strictly isolated and never used to train public models. Only anonymized, non-identifying market trends are aggregated.
