execution plan into a projected cost and bid price. A sound estimate
,considers labor, materials, equipment, subcontractors, indirect costs, risks,
and the contractor's required margin.

construction estimate?

B. Contact the lowest-priced subcontractor
C. Thoroughly review the plans, specifications, addenda, contract
requirements, and other bidding documents
D. Prepare the final payment application
Rationale: The estimator must understand the complete scope before
assigning quantities and costs. Reviewing all current bidding documents
reduces the risk of omitting work or pricing obsolete requirements.
3. What is the primary purpose of a quantity takeoff?
A. To determine the contractor's tax rate
B. To establish employee classifications
,C. To determine the quantities of labor, materials, and other measurable
work required to perform the project D. To approve the owner's

unit costs and developing direct-cost estimates.

drawing should be used in a bid estimate?
A. Whether it has an attractive title block
B. Whether it was issued by a supplier
C. Whether it is the current, applicable bid revision identified in the
project documents

missing revisions, and inaccurate pricing. Estimators must establish
document control before relying on drawings for takeoff.

, B. A final warranty certificate
C. A written modification or clarification issued during the bidding period
that changes or supplements the bidding documents

clarify, or supplement the bid documents before bid submission. Estimators
must incorporate applicable addenda into their estimates and bid forms.
6. Why must an estimator carefully review all addenda before submitting
a bid?
A. Addenda are optional suggestions.
B. Addenda apply only after construction begins.
C. Addenda can change scope, quantities, specifications, schedule
requirements, or other conditions that materially affect the bid. D.

Rationale: Failure to incorporate an addendum can result in pricing the
wrong scope or failing to acknowledge a required change. Proper
addendum control is therefore an essential bidding responsibility.
