challenges.
5. When estimating a municipal sewer installation, which cost
category should include excavation, bedding, pipe, backfill, labor,
equipment, and restoration?
A. Only administrative overhead
B. Direct construction costs
C. Personal expenses

B. It provides uniform support and helps maintain the designed grade
and alignment
C. It eliminates the need for trench safety
D. It guarantees that groundwater cannot enter the excavation
Answer: B
Rationale: Proper bedding supports the pipe uniformly and helps
prevent point loading, settlement, displacement, and alignment
problems.
10. Which project document normally establishes the technical
requirements for materials, workmanship, testing, and construction
procedures?
A. Contractor business card
B. Project specifications
