Every price is built on assumptions. Capture them.
Lock every pricing, scope, and programme assumption with an owner and a status. The thinking behind your number travels with the project so the delivery team prices and builds against the same baseline.
Assumptions made at bid stage shouldn't disappear with the estimator.
Every tender number is built on assumptions exclusions, allowances, expected ground conditions, who supplies what, what's in scope and what isn't. They live in the estimator's head or scattered through emails and spreadsheets. When the job is won, those assumptions vanish, and the delivery team rebuilds the logic from scratch or worse, prices against a different baseline.
The Assumption Log captures each assumption at the point it's made, with an owner and a clear status. Caveats, exclusions and allowances are recorded against the bid so there's a single, auditable record of exactly what the price assumed.
When the contract moves to delivery, the assumption log feeds straight into the Handover Pack. The site team inherits the full commercial logic no guessing, no margin bleed from assumptions that never got passed on.
Owner and status on every entry
Each assumption has a named owner and a status so nothing sits unvalidated or forgotten.
Exclusions and allowances captured
Record caveats, exclusions and allowances against the bid as a single auditable source of truth.
Bid-to-site continuity
Assumptions flow into the Handover Pack so the delivery team prices and builds against the same baseline.
Margin protection
When assumptions are explicit and handed over, fewer surprises turn into cost overruns and disputes on site.
