First-principles cost estimating
Ground Truth Estimator is a workspace for Australian civil infrastructure companies to price projects the way a good estimator actually does it: labour, plant, and material rates assembled into build-ups, rolled up into categories, and stress-tested against a real risk register — not a single number pulled from memory.
One workspace per company. Your rates and projects are never visible to anyone outside your organisation.
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.
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.
Track project-level risk items alongside the estimate itself, so contingency is a considered number — not a round-up at the end.
A stacked breakdown of labour, plant, material, and markup for every project, so you can explain and defend a price at a glance.
Set up your workspace, bring in your rates, and start estimating your next project the way it should be priced.
