A. Follow the drawings because they are normally more detailed.
B. Follow the specifications because they control construction quality.
C. Ask the owner which requirement they prefer and proceed immediately.
D. Request formal clarification from the design professional and document the
direction.

encountered below the planned bearing elevation. What should the contractor
do first?
A. Pour concrete over the unsuitable material.
B. Remove and replace the material without notifying anyone.
C. Stop affected work and obtain direction regarding soil remediation.
D. Increase the concrete strength to compensate.
Answer: C. Stop affected work and obtain direction regarding soil remediation.
Rationale: Bearing conditions are critical to structural performance. The
contractor should document the condition and obtain appropriate engineering
or owner direction before changing the foundation design or subgrade
preparation.
3. Which estimating practice provides the strongest protection against omitting
major project costs?
A. Estimating only direct labor and materials.
B. Using the previous project's total cost as the new budget.
C. Developing a detailed quantity takeoff and incorporating direct, indirect,
overhead, and contingency considerations.
D. Applying a percentage to the architect's estimated construction cost.
Answer: C. Developing a detailed quantity takeoff and incorporating direct,
indirect, overhead, and contingency considerations.
Rationale: A comprehensive estimate accounts for measurable work as well as
supervision, equipment, temporary facilities, insurance, permits, overhead, and
other project costs.
,4. A subcontractor performs work that does not conform to the approved plans.

Answer: B. It documents authorization and establishes the agreed cost and time
effects.
Rationale: Changes affecting price or time should be documented before
execution whenever practical. A properly executed change order establishes a
clear contractual record.
8. A concrete slab is specified with a particular compressive strength. Which
factor has the greatest direct influence on achieving the specified strength?
A. Concrete color.
B. Water-cementitious materials ratio and proper curing.
C. Formwork color.
D. Exterior air temperature alone.
Answer: B. Water-cementitious materials ratio and proper curing.
