Temelion turns the bills of quantities from your awarded contracts into a searchable price database, then builds estimates you can source, explain and defend.

Every estimate is built on real bill-of-quantities lines, with the source identified,
the cost index applied and a confidence range.

Bring in your history.
Upload bills of quantities and quotes, in Excel or PDF. Temelion normalises them, extracts unit prices and tags each project with its type, region, floor area, trade package and phase.
Anything that looks off is flagged for you to check.
Explore your price database.
Filter by region, project type, floor area, period, trade package or keyword, with cost-index updates set per package. Or just ask in plain language: the AI platform sets the filters for you, and stays in sync as you adjust them. Every ratio comes with:


Estimate at every phase.
Start a project at concept stage. Work from a global ratio at concept and preliminary design, then line by line at detailed design. Temelion produces an auditable estimate that shows its sources, filters and method. Export to Excel or PDF, in your own deliverable formats.
Every contract you win sharpens the next estimate.
Only bills of quantities from awarded contracts are added to your database, never every quote received. The affected ratios are recalculated automatically, and every update is notified, explainable and reversible.
