are valuable for project management and can become important if a
dispute arises.

those shown in the contract documents. What should the contractor
generally do first?
a. Conceal the condition
b. Proceed without documenting it
c. Notify the appropriate project representative and document the
condition

Rationale: Unexpected site conditions can affect cost, schedule, and
construction methods. Prompt written notification and documentation

before substantial additional work is performed.

calculating quantities of individual materials and labor requirements?
a. Guess estimating
b. Historical pricing only
c. Quantity takeoff estimating
d. Percentage-of-completion estimating
Rationale: A quantity takeoff identifies the amount of materials,
labor, and other resources required. Applying appropriate unit costs
