,specialty trade. Its published content areas include general requirements,

systems, finishes, mechanical and plumbing systems, electrical systems,
and procurement and contracting requirements.

D. Procurement and Contracting Requirements
Rationale: The published outline allocates 31 questions to Procurement
and Contracting Requirements, making it the largest single content area.

contains 15.

highest-weighted subjects. Which combination should receive
substantial study attention?
A. Concrete and masonry only
,B. Wood and finishes only

artificially low and financially dangerous bid.

A. Only the original drawings
B. Only the contractor's preliminary estimate
C. Only the specifications
