For civil contractors & quantity surveyors
Build estimates from the ground up — not from a gut-feel per-metre rate.
First-principles cost estimating and cost control for civil infrastructure. Labour, plant, and material rates assemble into build-ups, get stress-tested against a real risk register, then carry through to actual cost and earned value once work starts.

Your own rates, reused everywhere
Build a labour, plant, and material rate library once. Every new project draws from the same source, so estimates stay consistent as your business's real costs change.
Quantities straight off the drawing
Measure lengths, areas, and counts on your PDF or DXF drawings, with a scale for every page and a live running total, then send them into the estimate. How takeoff works
Costs built from first principles
Every line item is assembled from its actual labour, plant, and material components — not typed in as a lump sum you can't defend later.
Contingency you can point to
Track project-level risk items alongside the estimate itself — with live geotechnical and weather lookups for your site — so contingency is a considered number, not a round-up at the end.
See where the number comes from
A stacked breakdown of labour, plant, material, and markup for every project, so you can explain and defend a price at a glance.
A range you can defend, not a guess
Every risk in the register feeds a simulation of thousands of possible outcomes, giving you a best case, an expected case, and a worst case — a credible range for a client or tender panel, not one number that quietly hides the uncertainty.
Schedule the work, register who's running it
Give each category a planned start and end date — link one to another's finish the way Microsoft Project's Predecessor field does — and register every site or support role's Wage or Salaried rate, ready to compare against real cost.
Track real cost and progress, not just the estimate
Log real Labour, Plant, Material, and Subcontract cost against the same Rate Library used in the estimate, record % complete as work happens, and see Earned Value and Actual Cost — so the number you defended at tender keeps being checked against the job.
One account per company.
Set up your workspace, bring in your rates, and start estimating your next project with numbers you can actually defend.
