A clearer basis for your next NZ build

By turning complex architectural blueprints into precise, data-backed budgets, we ensure your high-value tenders are built on a rock-solid foundation.

We organise quantities, project-specific pricing assumptions and scope notes into a clear basis for review. Supplier rates, design requirements and site conditions are confirmed for the individual New Zealand project.

Construction Estimating
The SJEH estimating sequence

Your New Zealand project.
Three deliberate steps.

From the latest drawing revision to a structured quantity schedule, each stage makes your construction estimate easier to review.

  1. 01
    Define the brief

    Start with the right information.

    Share the plans, specifications, NZ project location and tender deadline. We agree the scope, drawing set and estimating fee before starting.

    Your drawing checklist ↗
  2. 02
    Measure & review

    Make the scope visible.

    Measure the agreed trades and organise the quantities. Record assumptions, design gaps and pricing allowances so your team can review the basis.

    Explore measured schedules ↗
  3. 03
    Handover & next steps

    Put the detail to work.

    Receive the agreed breakdown and query notes. Use them to compare supplier quotations, review budgets or prepare your New Zealand tender.

    From measurement to review

    The drawing is the start.
    The workflow makes it useful.

    Three distinct examples: a home floor take-off, a commercial drawing revision and a material schedule. Scroll through the workflow or use the stage links.

    01 / PlanSwift

    Area & length take-off

    Follow an area trace around a residential floor zone. The measurement closes back on its starting point before the quantity is recorded.
