Problem $2$

$15\mathrm{.}2$ Estimate the total direct cost and cost per $1,000$ bricks for construction of walls

of a rectangular building, $75$ ft $6$ in $.$ wide and $340$ ft $0$ in $.$ long, with brick veneer

walls $10$ ft high. The total area of openings for doors and windows will be $560$

sf$.$ The walls will be $4$ in$.$ thick, using Norwegian type bricks laid in common

bond with $(1)/(2)-$in$.$ mortar joints on all sides. A header course will be placed every

fifth course between the stretcher courses. Wall ties will be placed every $16$ in$.$

in the horizontal direction and every $24$ in$.$ in the vertical direction.

Material cost will be $$(612)/(1),000$ bricks, $$(83)/()$ cy for mortar, and $$(4\mathrm{.}25)/(100)$

wall ties. Labor costs include $$(20\mathrm{.}95)/($h$)$r for bricklayers and $$(15\mathrm{.}56)/($h$)$r for

helpers. The mixer for mortar will cost $$(9\mathrm{.}50)/($h$)$r$.$ Scaffolding rental will be

$$1,800$ for the job.
