STAGE 4 — TAKE-OFF, BOQ AND COST
Bill of quantities and cost comparison
Quantities measured from the native Revit take-off of each run's model (or the design model), priced with an editable rate library. Seeded rates are ILLUSTRATIVE — not verified market rates.
ILLUSTRATIVE — not verified market rates
The seeded library is a Hexanta assumption for the synthetic demo (source “Hexanta illustrative assumption”, confidence LOW). It is not a cost plan for tender; quantities are not checked by a quantity surveyor and nothing here is engineer or QS signed off. Controls, insulation thickness and valve sets are ASSUMED allowances where the model holds none.
Native Revit take-off (recorded pairing)
Measured from the native Revit models: baseline Run 3 (baseline) — wf1-NATIVE-REVIT-APS-MEP-20261019-e963993a (PARTIAL — owner-accepted for the frozen Run 3 baseline (WF1_MASTER rows 24h and 30)); change Run 4 (owner change) — wf1-NATIVE-REVIT-APS-MEP-20261019-1ce22c7e (PASS — accepted Run 4 model (WF1_MASTER row 41; RUN4_BASELINE_FREEZE)). Items the models do not hold (controls, accessories, insulation thickness) stay ASSUMED allowances. Choose “Design model” below to compare on route centrelines instead.
