Fine grade for slab (Area Condition in SF- of Slab 24’ x 36’) 2. Excavation and Backfill for all foundation trenches (End area method Cross Section of Trench 2’ x1’ x the Perimeter of the slab in cubic yards). Concrete: Assumptions: 3,000 psi concrete: Rebar sticks are 40’ and lap is 38 bar diameters (a rebar diameter is measured by 1/8 of an inch i.e. a number 4 rebar is 4/8th of an inch or ½” in diameter.) . WWM is in 50’ x 4’ rolls with 6” of lap on all sides. (Rebar and Reinforcing are extra credit) 1. 24’ x 36’ x 4” slab on grade with one layer of 6x6~W2.1xW2.1 WWM (Trowel Finish) ( Cubic yards) 2. 2’ x 1’ Continuous spread footers under slab turn down including 2 # 4 rebar (cubic yards) 3. Sub-base 6” of gravel with 10 mil vapor barrier (both area Conditions ) Masonry: Assumptions: 14’ CMU Masonry has bond beams every 48” and vertical reinforcing 24” O.C. Consisting of grout and # 4 rebar. Unreinforced spaces will remain hollow! Reinforcing Extra Credit 1. 8” x 16” x 8” CMU around perimeter of building (assume no openings for now) Area Condition SF) 2. Brick Veneer on the outside of CMU (Area Condition SF)
