Material Dimensional tolerance

Dimensional notation in construction documents must also consider dimensional tolerances associated with various materials. For example, construction standards published by American Concrete Institute (i.e. ACI 117) are commonly referenced in project specifications, which should be coordinated with relevant detail drawings. In concrete formwork for a 40 foot building, allowance must be considered for upto 1/2 inch (Choose 2)
A. in 10 feet variation from level in slab soffits, ceilings, and beam soffits
B. minus (negative) variation in plan dimensions of footings
C. plus (positive) variation in plan dimensions of footings
D. plus (positive) variation in cross-sectional dimensions of columns & beams (thickness of slabs & walls)
E. in any bay, or 20 ft maximum variation of linear building lines (from set position in plan and related position of columns, walls, and partitions)


Answers B and D are correct. A = 1/4 inch, C = 2 inches, E = 1/4 inch

Deflection: steel or wood

For EITHER steel or wood beams, a question that asks for the allowable deflection limit (maximum) for live loads only requires which of the following equations? A. L/240 B. L/360 C. ∆ = 5wl⁴ / 384EI D. ∆ = 5Wl³ / 384EI Answer B. L/360 or span in inches divided by 360. ARE 4.0 exam prep: SS Note on calculations: From posted discussions on AREforum , memorization of most equations is not advised. However, even when the equation may be available in in-exam reference, selection of the appropriate equation requires correct identification.

Facility parking

A new office complex is being planned, which is required to include 162 parking spaces. In addition to the parking spaces, allow for related driveways and walkways to estimate the area of the parking lot that would satisfy this number of spaces. A. 1.0 acres B. 1.5 acres C. 1.75 acres D. 2.0 acres Answer B. 1.5 acres. Multiply the required parking spaces by 400 sf per car (1 acre = 43,560 sf). If walkways are not required, use 300 sf per car. ARE 4.0 exam prep: SPD
