1The South Carolina Nonstructural Renovation commercial-contractor classification covers interior and exterior finishes, partitions, windows, doors, millwork, and similar work. Which activity is outside that classification?
A.Installing acoustical ceiling panels
B.Altering a load-bearing beam or column
C.Hanging load-bearing or nonload-bearing drywall partitions
D.Installing vinyl composition tile flooring
Explanation: The PSI Candidate Information Bulletin and S.C. Code scope for Nonstructural Renovation expressly exclude alterations to load-bearing portions of a structure. Acoustical ceilings, drywall partitions (including load-bearing gypsum partitions), and hard flooring other than carpet are inside the classification.
2A floor plan is drawn at a scale of 1/4 inch = 1 foot 0 inches. A partition measures 3-1/2 inches long on the drawing. What is the actual partition length?
A.7 feet 0 inches
B.10 feet 6 inches
C.14 feet 0 inches
D.28 feet 0 inches
Explanation: At 1/4 inch = 1 foot, each inch on the drawing equals 4 feet. 3-1/2 inches × 4 feet per inch = 14 feet. Always convert the plotted length using the stated architectural scale before taking off material.
3A rectangular room is 16 feet by 20 feet with a 9-foot ceiling. How many 4-foot by 8-foot gypsum boards are required for the walls only, single layer, after deducting two 3-foot by 7-foot doors and applying a 10 percent waste allowance? Round up to a whole sheet.
A.19 sheets
B.21 sheets
C.23 sheets
D.26 sheets
Explanation: Perimeter = 2 × (16 + 20) = 72 feet. Gross wall area = 72 × 9 = 648 square feet. Door deduction = 2 × 21 = 42 square feet. Net area = 606 square feet. Sheets before waste = 606 ÷ 32 = 18.94. With 10 percent waste: 18.94 × 1.10 = 20.83, which rounds up to 21 sheets.
4On a commercial renovation set, where does the estimator find the required door size, fire rating, hardware set, and glass type for each opening?
A.The civil site plan only
B.The door and finish schedules keyed to the floor-plan marks
C.The structural foundation notes
D.The plumbing riser diagram
Explanation: Door marks on the floor plan (for example D-101) key to a door schedule that lists width, height, material, fire-protection rating, glazing, and hardware set. Finish schedules likewise assign paint, flooring, and wall covering. Estimators take quantities from those schedules, not from civil or MEP drawings.
5A contractor must paint 2,800 square feet of wall with a product that covers 350 square feet per gallon per coat. Two coats are specified and a 10 percent waste allowance is required. How many gallons should be ordered, rounded up?
A.8 gallons
B.16 gallons
C.18 gallons
D.22 gallons
Explanation: Two coats require 2,800 × 2 = 5,600 square feet of coverage. 5,600 ÷ 350 = 16.00 gallons net. With 10 percent waste: 16 × 1.10 = 17.6 gallons, which rounds up to 18 gallons.
6A partition is 48 feet long. Wood studs are specified at 16 inches on center, including a stud at each end. How many studs are required for the run, ignoring extra jack or king studs at openings?
A.36 studs
B.37 studs
C.48 studs
D.49 studs
Explanation: Convert length to inches: 48 × 12 = 576 inches. Number of spaces = 576 ÷ 16 = 36. Number of studs = spaces + 1 = 37. The extra stud accounts for both ends of the run.
7A 24-foot by 36-foot ceiling will receive 4-foot by 12-foot gypsum panels hung perpendicular to joists. Using a 15 percent waste factor for a cut-up ceiling with lights and soffits, how many sheets should be ordered?
A.18 sheets
B.20 sheets
C.21 sheets
D.24 sheets
Explanation: Ceiling area = 24 × 36 = 864 square feet. Each 4×12 panel covers 48 square feet, so the net count is 864 ÷ 48 = 18 sheets. With 15 percent waste: 18 × 1.15 = 20.7, which rounds up to 21 sheets.
8Under IBC 2021 Section 1010.1.1, what is the minimum clear opening width of a swinging means-of-egress door, measured with the door open 90 degrees?
A.28 inches
B.30 inches
C.32 inches
D.36 inches
Explanation: IBC 1010.1.1 requires a minimum clear opening width of 32 inches, measured between the face of the door and the stop with the door open 90 degrees. A 36-inch nominal door is commonly used to achieve that clear width after hardware and stops.
9Per IBC 2021 Section 2406.4.1, glazing in which of the following is a hazardous location that generally requires safety glazing?
A.A small decorative leaded-glass insert that will not pass a 3-inch sphere
B.Fixed or operable panels of swinging, sliding, and bifold doors
C.A high transom whose bottom edge is 72 inches above the floor and is not in a door
D.Curved glazed panels of a revolving door
Explanation: IBC 2406.4.1 treats glazing in all fixed and operable panels of swinging, sliding, and bifold doors as a hazardous location requiring safety glazing (typically tempered or laminated), subject to listed exceptions such as very small openings, decorative glazing, and revolving-door curved panels.
10When framing a rough opening for a prehung 3-foot 0-inch by 6-foot 8-inch interior door, what is the typical rough-opening allowance used by carpenters?
A.Exactly the slab size, with no extra width or height
B.About 2 inches wider and 2 to 2-1/2 inches taller than the door unit to allow shimming and a header
C.6 inches wider and 6 inches taller than the door
D.The same as the finished casing dimensions
Explanation: A prehung 3-0 × 6-8 door is commonly framed at about 38 inches by 82 to 82-1/2 inches. The extra width and height provide space for the jamb, shims, and a level, plumb installation. Feirer’s Carpentry and Building Construction uses this industry allowance.
