CEP Quantity Takeoff & Measurement 2 — Questions and Answers
Question 1: In quantity takeoff, board feet (BF) is the standard unit for measuring which material?
- Concrete formwork panels
- Lumber and timber products (Correct answer)
- Steel reinforcing bar
- Rigid insulation board
Correct answer: Lumber and timber products
Board feet is the traditional US unit for lumber and timber, defined as a piece equivalent to 1 inch thick × 12 inches wide × 12 inches long in volume.
Question 2: Which of the following best describes the 'net quantity' approach in a construction takeoff?
- Including all waste and overage in the measured quantity
- Measuring only the actual installed quantity without waste allowances (Correct answer)
- Accounting for subcontractor markup in the measured amount
- Calculating quantities after deducting the project contingency
Correct answer: Measuring only the actual installed quantity without waste allowances
Net quantity measures the exact installed amount without waste or overage; waste factors are then applied separately to arrive at the purchase quantity.
Question 3: What is the standard industry unit for measuring roofing shingle quantities in a quantity takeoff?
- Square feet (SF)
- Rolls
- Square (100 SF) (Correct answer)
- Cubic yards (CY)
Correct answer: Square (100 SF)
Roofing materials are measured in 'squares,' where one square equals 100 square feet of coverage area, which is the industry standard unit for roofing.
Question 4: When calculating steel reinforcing bar (rebar) quantities, what unit is most commonly used for purchasing and pricing?
- Linear feet (LF)
- Pounds (LB) or tons (Correct answer)
- Cubic yards (CY)
- Each (EA) by bar size
Correct answer: Pounds (LB) or tons
Rebar quantities are first calculated by length and then converted to weight (pounds or tons) because steel is purchased and priced by weight in the industry.
Question 5: What is the purpose of a 'quantity survey' or 'material schedule' in the takeoff process?
- To schedule material deliveries to the job site
- To compile and organize all measured quantities by trade or work section (Correct answer)
- To survey subcontractor bid prices
- To track actual versus estimated quantities during construction
Correct answer: To compile and organize all measured quantities by trade or work section
A quantity survey compiles and organizes all measured quantities by trade, CSI division, or work section, making pricing, review, and scope management more efficient.
Question 6: What does 'CY' represent in standard quantity takeoff notation?
- Current year cost index
- Cubic yard (Correct answer)
- Calendar year basis
- Construction yield factor
Correct answer: Cubic yard
CY stands for cubic yard, the standard US unit for measuring volumetric materials such as concrete, earthwork, gravel, and other bulk materials.
Question 7: When measuring wall area for painting in a quantity takeoff, what is the standard practice for door and window openings?
- Always include the full gross wall area without any deductions
- Deduct all openings larger than a specified threshold (commonly 100 SF) (Correct answer)
- Deduct all openings regardless of size
- Add a premium factor for cutting-in around openings instead of deducting
Correct answer: Deduct all openings larger than a specified threshold (commonly 100 SF)
Standard painting takeoff practice deducts openings only when they exceed a threshold (commonly 100 SF per opening) because small openings require similar effort to paint around as to cover.
