What Makes Us Different

Not a Generic Online Quantity Take-Off Service

Our estimating process is built on practical construction experience — construction documentation, building methods, materials and real-world costs — not just computer-generated quantities.

01 — Measurement

Accurate Measurement From Drawings

We measure directly from architectural and structural drawings using AutoCAD and professional digital measuring tools — not generic floor-area rates or broad allowances.

02 — Reporting

More Than Just a Quantity Schedule

Measured quantities are developed into a trade-by-trade Construction Estimating Report — with applicable SANS / Building Regulation requirements, construction notes, material specifications and finishes.

03 — Experience

Practical Construction Knowledge

Our process combines architectural drawing interpretation, digital measurement and hands-on construction experience — so the information is genuinely usable for tendering, budgeting and decisions on site.
