Describe the work method first
Start with the installation sequence, access, material handling, equipment, shift conditions, and quality requirements. The crew should follow from the work method.
Copying a familiar crew into a different site condition can produce a precise but unusable labor extension. Use the construction labor productivity estimating as the related control and keep the record with the estimate revision under review.
Build the crew from actual roles
List each classification, headcount, burdened rate basis, and whether the role is productive, supervisory, or equipment support. Check agreement obligations and project rules with the contractor responsible for labor compliance. Do not hide foremen or operators in a blended rate without documenting the blend.
AACE recommended practices offer general estimating references. The project documents, contractor procedures, and approved estimate remain the controlling basis for the decision.
| Review field | Required record |
|---|---|
| Method | Sequence, access, and equipment |
| Crew | Roles, counts, and rate basis |
| Output | Quantity per crew-hour or shift |
| Check | Hours, duration, and sensitivity |
Test production and cost together
Calculate crew-hours from the proposed output and compare the result with the schedule area, quantity, and available work fronts. Run a small sensitivity check on the uncertain production input.
If the estimate depends on uninterrupted access, state that condition beside the labor build-up. Use the construction crew rate calculator as the related control and keep the record with the estimate revision under review.
