For a shower installation, Part 2 of the waterproofing specification identifies the membrane, while Part 3 requires a flood test before tile installation. The product submittal is approved, and the correct membrane has been delivered. Which additional record demonstrates compliance with the specified requirement for releasing the shower to the tile setter?
Correct answer: B - A passing flood-test record for the installed shower waterproofing
Today's inspection record releases the bedrooms for drywall but leaves the new bathroom awaiting rough-plumbing inspection. The permit requires approval before that piping is concealed. The drywall crew is available now. What direction keeps useful work moving while honoring the inspection requirement?
Correct answer: B - Leave the bathroom piping exposed and assign the crew to the released bedrooms
A contractor is paid to replace a painted window, including its frame, in an occupied three-bedroom house built in 1964. The painted area disturbed is only 4 square feet. No valid determination that the affected paint is lead-free has been made, and no housing exclusion applies. Under the federal EPA Renovation, Repair and Painting Rule, how is this work classified?
Correct answer: D - Covered renovation because window replacement does not qualify for the minor-repair exclusion
An extension ladder provides access to a roof landing. Its side rails extend 18 inches above the landing and cannot extend farther because of the ladder's length. The top is secured to a rigid support that will not deflect, and a suitable grabrail is installed for the transition. The footing, angle, and other safety requirements are satisfied. Under federal OSHA's upper-landing access provision, which assessment is correct?
Correct answer: D - The secured top and grabrail satisfy the permitted alternative to the three-foot extension
The homeowner says, "You told me I'd have my kitchen back Friday." Friday is the scheduled cabinet-installation milestone; countertop installation and plumbing reconnection come later. The lead carpenter has not established what the homeowner expects to be usable. Which reply best checks that expectation while correcting the schedule misunderstanding?
Correct answer: C - "Does 'back' mean ready for cooking and washing dishes? Friday is cabinet installation, not a functioning kitchen."
Rain staining keeps returning on an interior wall just below the point where a porch roof ends against the house. The asphalt shingles and step flashing farther up the sidewall are intact. At the eave, runoff follows the siding instead of entering the gutter. Which detail would most directly correct this water path?
Correct answer: C - Kick-out flashing integrated with the wall drainage plane and directed into the gutter
A replacement stair has 120 inches of finished-floor-to-finished-floor rise and 157 1/2 inches of available horizontal run, excluding nosing projections. It will be one straight flight, with the upper floor serving as the landing. The project permits risers no higher than 7 3/4 inches and requires treads at least 10 inches deep. Considering these rise and run constraints, which layout fits?
Correct answer: A - 16 risers and 15 treads, with each tread 10 1/2 inches deep
Four otherwise equivalent replacement windows have the same whole-window U-factor and air-leakage rating. For an unshaded west-facing room that overheats in summer, the owner wants to limit solar heat gain while retaining as much daylight as possible. Which pair of NFRC ratings best serves both priorities?
Correct answer: C - Solar heat gain coefficient 0.28; visible transmittance 0.62
A carpenter argues that collar ties near the ridge make the lower rafter ties unnecessary when converting a ceiling to a vault. The roof uses a nonstructural ridge board, not a ridge beam. Which function of the lower ties does that argument overlook?
Correct answer: D - Resisting the rafters' tendency to push the exterior walls outward
