Speed up tendering with clear, builder-ready BOQs
What We Cover Under Cost Estimation Services
Material Measurement & Takeoff
We extract material quantities from your drawings and schedules using trade-specific logic. Each takeoff is adjusted for site conditions, construction sequence, and detailing. The result is a BOQ that reflects how the work will actually be delivered on site.
Common items covered include:
- Roof sheets and flashings
- Floor and wall tiles
- Paint coverage areas
- Concrete volumes and pours
- Fit-out and finish scopes
Material Pricing & Costing
We integrate pricing into your BOQ based on your preferred rates or current NZ supplier data. This helps you stay in control of budgets, supplier requests, and pricing across multiple trades.
How it helps:
- Apply real-time pricing for better accuracy
- Align with supplier quote formats
- Use for tender submissions or cost comparison
Labour Allocation & Planning
Labour estimates can be included based on tasks, areas, or trade-specific productivity benchmarks. We help you scope workforce effort and align with installation timelines or subcontractor quotes.
Common use cases:
- Estimate laying or installation hours per trade
- Assess labour needs for multi-zone projects
- Plan resources across residential or commercial work.
Waste Allowances & Overlaps
We apply trade-specific waste factors that reflect how materials are used and lost on site. Every estimate accounts for layout loss, breakage, cutting, and overlaps where applicable.
Examples include:
- Tile breakage, cutting loss, and spacing
- Roof sheet overlaps and profile loss
- Paint absorption and prep coat waste
- Concrete edge trimming or formboard loss
Trade-Specific BOQ Formats
Every report is formatted to suit the trade it covers. We don’t use generic templates. Each file reflects how builders, QS teams, or suppliers expect to receive it.
You’ll get:
- Structured Excel with grouped items by zone or scope
- PDF version for sharing or review
- NZS4202 format available on request
- Supplier-ready layout with clear headings and descriptions

Our Approach to Cost Estimation
At BigEstimate, cost estimation isn’t just about quantity takeoffs, it’s about reducing friction,
increasing win rates, and helping NZ contractors run profitable projects.
Trade-Centric Thinking
Each estimate is scoped by trade, so roofing reports look nothing like tiling or insulation ones. This keeps your quotes clean and your subs on the same page.
NZ Code & Builder Format Compliance
We align every output to what local builders and suppliers expect, right down to fixings, fasteners, and wastage buffers.
Data-Led Accuracy + Human Oversight
We use software like Planswift, but every project is reviewed by a senior estimator before delivery. So you’re getting both precision and accountability.
