Using Figures 22-2 and 22-3, determine the cost for a 250-foot by 200-foot warehouse. The exterior walls are to be concrete block, which are used as bearing walls. The warehouse is 20 feet high. Include ten 7-foot by 8-foot dock levelers in the costs.
What will be an ideal response?
The cost is as follows:
Area = 250? × 200? = 50,000 sf
Perimeter = 250? + 200? + 250? + 200? = 900?
From Figure 22-2, the cost per sf for a concrete block warehouse with bearing walls and an area of 50,000 sf is $71.05 per sf. From Figure 22-2, the base perimeter is 966 lf and an add of $1.30 per sf per 100 lf of perimeter.
Add for Perimeter ($/sf) = (900? – 966?) / 100? × $1.30 per sf per 100 lf
Add for Perimeter ($/sf) = $0.86 per sf deduct
From Figure 22-3, the base story height is 24? and from Figure 22-2, the adjustment for story height is $0.40 per sf per foot of height.
Add for story height ($/sf) = (20? – 24?) × $0.40 per sf per ft = $1.60 per sf deduct
Base cost ($/sf) = $71.05 per sf – $0.86 per sf – $1.60 per sf = $68.59 per sf
Base cost ($) = 50,000 sf × $68.59 per sf = $3,429,500
From Figure 22-2, the added cost for a 7?×8? dock leveler is $6,225 per leveler.
Dock levelers = 10 ea × $6,225 per ea = $62,250
Total cost = $3,429,500 + $62,250 = $3,491,750 – Use $3,500,000
