The biggest decisions about cost are made early, often before the drawings are detailed enough to measure. That is when an elemental estimate is most useful.
What is an elemental estimate?
Instead of pricing every item, an elemental estimate prices the building by major element: substructure, structure, envelope, internal finishes, services and external works. Rates are drawn from comparable projects and adjusted for your quality level and site.
Why use one?
- Test affordability. Find out early whether the concept fits the budget.
- Compare options. See how changes in size, shape or finishes affect cost.
- Guide design decisions. Know which elements drive cost.
- Support early conversations. With lenders, partners or advisers.
How accurate is it?
An elemental estimate is a guide, and it carries a wider allowance than a measured estimate. As the design develops, the estimate can be refined and replaced by a full-rate estimate.
Elemental versus full-rate
| Stage | Estimate type | Based on |
|---|---|---|
| Concept / feasibility | Elemental | Areas, sketch plans, benchmarks |
| Developed design | Elemental or measured | Developed drawings |
| Construction documents | Full-rate | Measured quantities and priced items |
