|
|
Construction estimating is a subset of cost estimation.
|
|
|
|
## 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* Proposals to GC's can be withdrawn for any reason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* Proposals from subcontractors can be withdrawn for any reason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 [[strategy#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.
|
|
|
|
## Ethics
|
|
|
|
Clients engaging in unethical bidding practices can quickly gain a reputation for doing so,
|
|
leading to reduced bid response that can be impossible to fully recover from.
|
|
|
|
To ensure a transparent bidding process, one must
|
|
|
|
* divulge all selection criteria to bidders,
|
|
* avoid conflicts of interest,
|
|
* maintain confidentiality of bid submissions, and
|
|
* provide equal access to bidding information.
|
|
|
|
For unacceptable behavior see [[bad-bid-practice]].

|
|
> in order to solicit lower bids.
|
|
> The competing quote may be legitimate, fabricated,
|
|
> or a non-serious proposal from a colluding vendor.
