During a field-measurement visit, a drafter discovers that one end of a temporary guardrail beside an open stairwell is unsecured. The opening is not otherwise protected, and the drafter can move away along a clear route. What is the appropriate immediate action?
Correct answer: C - Withdraw from the edge and notify the site supervisor.
Field dimensions for a rectangular cabinet are 48 in wide across its front, 18 in deep, and 84 in high. A drafter is constructing front, top, and right-side orthographic views at the same scale. The outer boundary of the right-side view should represent:
Correct answer: A - 18 in horizontally and 84 in vertically
A wood-framing elevation shows a header over a door, full-height king studs beside the opening, and cripple studs above the header. The approved detail requires the header ends to bear on vertical wood members extending to the bottom plate; those members are missing from the elevation. What should be added?
Correct answer: C - Jack studs beneath header ends, extending to the bottom plate
A roofing takeoff covers both slopes of a symmetrical gable roof. Its horizontal projection measures 24 ft by 36 ft to the roof edges, including all overhangs. The ridge parallels the 36-ft side, and each roof plane rises 5 in for every 12 in of horizontal run. There are no openings. Before adding waste, what sloping surface area belongs in the takeoff?
Correct answer: C - 936 sq ft
A drafter is annotating existing plumbing after a survey. A seldom-used floor drain has a dry trap, and a reported sewer-gas odor disappears when water is added. Wastewater otherwise drains freely. Which function has the added water restored?
Correct answer: B - Water has restored the trap's barrier against sewer-gas entry.
The drawing register identifies A202 Revision 3 as the current authorized construction issue. A Revision 4 working file has a later modification date but is marked 'Coordination only.' The contractor, who has Revision 2, requests the current construction sheet. Under a procedure allowing only authorized construction issues to be sent for site use, the drafter should:
Correct answer: D - Issue Revision 3 with a transmittal identifying it as the current sheet.
A new manual hinged doorway on an accessible route is subject to the 2010 ADA Standards, with no applicable exception. The opening is 8 in deep. With the leaf open 90 degrees, the unobstructed distance from the door face to the opposite stop is 33 in; there are no projecting obstructions. Reviewing only the clear-opening-width requirement, what is the correct finding?
Correct answer: C - It meets the requirement; the measured clear opening exceeds 32 in.
Each cabinet centerline in a millwork layout must be set out independently from Grid B. The draft locates the first cabinet from Grid B, then chains the remaining centerlines from one another. Which dimensioning revision prevents a setting-out error at the first cabinet from being carried through the rest of the row?
Correct answer: A - Dimension each cabinet centerline independently from Grid B.
A proposed surface-drainage route runs from elevation 101.20 ft beside a building to 100.60 ft at a swale low point, then to an outlet at 100.90 ft. All elevations use the same datum, and grades are straight between these points. There is no other outlet or pumped drainage. Which review finding is supported by this profile?
Correct answer: D - The low point lacks a continuously downhill surface path to the outlet.
A flooring order covers a 12-ft by 20-ft lobby and a separate 8-ft by 10-ft alcove. A fixed cabinet occupies a 2-ft by 10-ft footprint within the alcove; the takeoff excludes flooring beneath it. Purchasing requires an additional 10% of the net floor area for cutting waste. Each carton covers 24 sq ft. What is the minimum number of whole cartons to order?
Correct answer: B - 14 cartons
