 Construction estimating is a subset of cost estimation.
 
-## Purpose
-
-The purpose of [[construction-estimating]] in practice
-is not to determine the cost of the scope,
-which would take far longer than allotted for bid,
-
-### For the Solicitor
-
-* Determine feasibility of functional requirements

-> [!info] Type 2 Owners
-> For some owners, money is no object,
-> and standardization is far more important
-> than any potential construction savings.
->
-> These owners can be expected to decline every [[value-engineering]] option offered
-> (see [[gold-plating]]).
-
-### For the Contractor
-
-* Make profit to meet growth target
-* Secure work for current and projected employees (fill backlog)

-
-> [!aside]
-> I take increasing issue with the common model
-> of measuring operational success by negative overrun,
-> as it is incompatible with the preferable target of estimate certainty.
-
-#### The Role of the Estimator
-
-The role of the estimator is to model the potential cost distribution of the project,
-taking actions to reduce the model's uncertainty.
-
-The effect of estimating methods can be represented as $d\sigma$,
-thus efficiency is $\frac{d\sigma}{dt}$.
-
-#### The Role of the Executive
-
-The role of the executive is to allocate profit and contingency
-according to the potential cost distribution
-weighted by the organizational desire to win the project.
