Construction Estimating |
Construction Estimating
Construction estimating is a subset of cost estimation.
Scope
This note is intended for: facts that are about the profession, specifically, as it is currently practiced.
For philosophy see bid-process-strategy
Misconceptions
Standard Practices
In general, many things thought to be standard are quite the opposite.
- Use of square receptacle symbols
Proposals
Proposals are not legally binding, which is a double edged sword for intermediate subcontractors like electrical:
- Proposals to GC's can be withdrawn for any reason
- Proposals from subcontractors can be withdrawn for any reason
This is obviously not popular practice, however it is important to recognize that errors aren't set in stone until a contract is signed.
Destigmatizing proposal retraction is of critical concern for subcontractors. See estimating-culture for more on estimate error game-theory.
It's important to recognize that retracting a proposal may upset a few people employed by the GC, but consider how little your own opinion matters to your company's strategic decisions. Much bigger people are involved after the proposal is accepted.
