After an approved partition relocation, a room dimension displays the revised width. However, the partition's model coordinates and the measured wall-to-wall distance remain unchanged. The drafter discovers that the dimension text was overridden. How should the revision be completed without concealing the discrepancy?
Correct answer: B - Move the partition geometry and restore a dimension linked to that geometry.
The enlarged window-head section shows the wall's upper drainage membrane passing behind the vertical upstand of the head flashing. The flashing's outer edge drains to the exterior, and its drainage outlets remain open. Water traveling down the membrane can therefore enter behind the flashing. Choose the correction that restores the gravity drainage path.
Correct answer: B - Lap the upper drainage membrane over the flashing's upstand.
A topographic drawing of ordinary terrain shows contours bending into successive V shapes along a shallow landform. The tips point west, toward the higher contour elevations. A proposed runoff arrow along the landform points west. The correct interpretation is:
Correct answer: D - A valley is shown, and runoff along it should instead be shown eastward.
Two parallel partitions are dimensioned 12'-0" apart, centerline to centerline. Each finished partition is 6 inches thick and centered on its dimension line. Casework projects 24 inches into the room from each opposing finished wall face. The project requires 92 inches clear between the casework fronts. Which clearance check is correct?
Correct answer: C - 90 inches clear; the layout is 2 inches short.
The product data for an engineered header describe thin wood veneers bonded with their grain predominantly parallel to the member's length. This construction identifies the header as:
Correct answer: C - Laminated veneer lumber (LVL)
In a symmetrical gable-roof section, the two bearing points are at the same elevation and 28'-0" apart. The ridge is centered between them. Each roof-slope line rises 6 inches per 12 inches of horizontal run and continues 2'-0" horizontally beyond its bearing point to the eave. Ignoring member thickness, what vertical rise should be dimensioned from the bearing elevation to the ridge?
Correct answer: D - 7'-0"
An accessibility review of a new public office records these dimensions at a manual swinging door: 33 inches clear between the face of the leaf opened 90 degrees and the stop; 62 inches of maneuvering depth on the front-approach pull side; and 15 inches of clear space beyond the latch side. The doorway is 8 inches deep, and the door has a latch but no closer. Under the 2010 ADA Standards, which review comment is justified?
Correct answer: A - Increase the latch-side clearance; this front-pull approach requires at least 18 inches.
A straight stair must connect finished floors 120 inches apart vertically. The project criteria require equal risers no higher than 7 inches and 11-inch tread depths. The upper floor serves as the final walking surface; there is no intermediate landing. Which geometry uses the fewest risers while satisfying the stated riser limit, with horizontal run measured between the first and last risers?
Correct answer: A - 18 risers, 17 separate treads, and a 15'-7" horizontal run.
Water beads uniformly on the outside of an uninsulated metal supply-air duct during dry weather. The duct interior and nearby water and condensate piping are dry. The duct's exterior surface is 51 degrees F, while the adjacent room air has a dew point of 58 degrees F. Which mechanism best explains the observed wetting?
Correct answer: D - Room-air moisture is condensing on the colder outer duct surface.
"Duplicate window tags" is written beside six openings marked W-1. The plan legend defines W-1 as a reusable window type. All six openings match the schedule's W-1 dimensions, operation, and glazing, and the W-1 row lists a quantity of six. How should the drafter resolve this review comment?
Correct answer: A - Retain W-1; the repeated tags correctly identify the scheduled type.
