At Grid C-4, architectural sheet A-201 dimensions a service opening at 3 ft 0 in, while the current structural detail on S-503 shows 3 ft 6 in. Neither document states which dimension governs. Fabrication is scheduled for Friday. Which request for information gives the design team the clearest basis for a timely decision?
Correct answer: A - A-201 shows 3 ft 0 in; S-503 shows 3 ft 6 in at C-4. Confirm the required width by Thursday for Friday fabrication.
Compaction tests on an approved clay fill repeatedly report 92% of the specified laboratory maximum dry density; the project requires at least 95%. The acceptable moisture range is 12%-16%, but field moisture is 19%. Lift thickness and the padfoot roller meet the placement plan, and extra passes have not improved density. Which adjustment targets the condition identified by these results?
Correct answer: D - Scarify and aerate the lift, then recompact and retest after moisture enters the specified range.
Excavation quantities are uncertain. The owner wants to pay for measured, accepted work while leaving the contractor responsible for labor and equipment overruns in the cost per unit. The pricing arrangement that assigns these risks as intended is:
Correct answer: C - Unit price for each measured unit of accepted excavation.
Water appears at the interior head of a window during wind-driven rain. Inspection shows that the head flashing slopes outward, but its upper flange lies over the face of the water-resistive barrier, leaving a reverse lap. The window's perimeter sealant is intact. Which repair addresses the defect in the drainage path?
Correct answer: D - Re-lap the barrier over the head-flashing flange so water drains onto the flashing.
Three mechanical subcontractors quote the same project. The apparent low quotation excludes controls and start-up; the other two include both. The estimate carries no separate allowance for either exclusion. To compare the quotations on an equivalent basis, the estimator should:
Correct answer: A - Confirm and price the exclusions before comparing the low quotation with the complete-scope quotations.
At the monthly review, a project's earned value report shows a cost performance index (CPI) of 1.08 and a schedule performance index (SPI) of 0.83. The project manager says, "We are spending efficiently, so our completion date is secure." Which assessment is supported by the report?
Correct answer: B - Cost efficiency is favorable; earned progress trails the plan, but a completion delay is not established.
A remaining-work schedule has two paths: A-B-D takes 18 working days, and A-C-D takes 17. A and D are shared by both paths. All links are finish-to-start with no lag. B can be shortened by up to 2 days at $900 per day, C by 1 day for $700, and D by 1 day for $1,300. A cannot be shortened, and there are no other paths or resource constraints. What is the least added direct cost of finishing in 16 working days?
Correct answer: C - $2,200
A crew is working in a 9-ft-deep trench protected by a designed shoring system. Following a rainstorm, the competent person sees fresh cracks along the trench edge and a displaced shoring member. The escape ladder is accessible. What takes priority before the cause is investigated?
Correct answer: C - Remove the workers from the affected trench and prevent reentry until protective measures restore safe conditions.
The project specification requires a 480-V air-handling unit. A reviewed product-data submittal shows a 208-V unit, but the contractor did not identify the deviation. The contract states that review does not approve undisclosed deviations; substitutions require separate written acceptance. The 208-V unit has not been ordered. How should procurement proceed?
Correct answer: B - Procure the specified 480-V unit unless the substitution receives separate written acceptance.
A grade check uses two level setups. Benchmark BM-1 is at elevation 100.00 ft. At the first setup, the backsight on BM-1 is 4.65 ft and the foresight on turning point TP-1 is 6.10 ft. After moving the level, the backsight on TP-1 is 5.25 ft and the foresight on existing ground at the stake is 4.10 ft. Design grade is elevation 99.20 ft in the same datum. What should be marked on the stake?
Correct answer: A - Cut 0.50 ft
