Milestone costing breaks your renovation into priced stages tied to physical progress on site. Framing complete. Services rough-in. Lock-up. Finishing. Each stage carries its own line items, its own pricing, its own checkpoint against actual.
Why it matters. A one-page price gives you a single number and little sense of how it was built. Milestone costing gives you a live picture. Where you are. Where you should be. What’s coming next. The CoConstruct portal shows every milestone in real time, so your project stays anchored to the plan.
Every YOURBUILDER project feeds the pricing dataset. The team logs hours against specific accounting codes every day. Roof framing, wall framing, cavity battens, cladding, roofing, insulation, flooring. After each project we pull the data into spreadsheets that track hours per task and cost per square metre.
This is real project pricing. 28 years of cost data across 273 Auckland projects (as of 2026). Internal painting at $85/sqm because that’s what the numbers consistently show. Subcontractor rates priced against actuals. Material prices cross-checked three times a year against Placemakers, Carters, and Bunnings.
The result. Cost variance of 1 to 3% against actual. Without a system like this, builders guess from the last job. That’s how a price ends up $35,000 to $40,000 short, with no record of where the money went.
The master pricing template is a line-by-line checklist of every likely material, labour rate, and hire cost. The QS works through each line and confirms nothing is missed. CEO Hamid Zwart calls this fixing the “master mistake” in construction. Human error.
The template carries 28 years of real project pricing. Every line gets updated against current market data. Every subcontractor rate sits against actual job results. Every material price is cross-checked against current supplier rates.
The output is a 33-page detailed proposal. Every cost itemised. Structural steel. Geotechnical requirements. Every trade involved. Hire equipment. The exact tapware. The industry standard is a one-page price with round numbers and a list of exclusions. Thirty-three pages against one tells its own story.
A builder’s price and a QS’s detailed proposal are different documents. Both have value. Different contexts, different stages, different decisions.
Builder pricing is judgement-led. It draws on field experience and the last comparable job. Useful for an early sanity check. Not enough for a bank-financing decision.
QS pricing is template-led. Every line item priced against historical actuals from our own dataset. Documented, defensible, detailed enough for lender approval.
Our in-house QS team works as a quantity surveying company and as a building company at once. Marain Datulayta (Senior QS, Project Manager) sits at the senior level of the team. That’s how seriously we take budget accuracy.
Yes. Concept Design Pricing is available as a standalone service for $1,500 to $3,000 depending on project size and complexity. You receive the same 33-page proposal produced by our in-house Senior Quantity Surveyor. The fee is refunded in full if you engage us for the build.
Cost variance against actual sits at 1 to 3 percent. The accuracy comes from real project pricing. We price new projects against recorded actuals from 273 projects (as of 2026), not from memory. Material prices in our master template are cross-checked three times a year against major suppliers.
Yes. Bring whatever plans, drawings, or earlier estimates you have. We work with external architects regularly, and Concept Design Pricing is available regardless of who developed the design. The Discovery Call assesses what you have and routes you to the right next step.
Yes. Our cost-plus-margin proposals have never been rejected by a bank or construction lender. The detailed costing with built-in contingencies satisfies lender documentation requirements. You can approach the bank for finance months earlier than with a typical builder’s rough numbers.
