5) In a building construction project, 7,500feet of insulated ductwork is required. The ductwork is made from 14-gauge steel costing $8.50 per pound. The 24-inch-diameter duct weighs 15 pounds per foot. Insulation for the ductwork costs $10 per foot. Engineering design will cost $16,000, and labor to install the ductwork will amount to $180,000. What is the total cost of the installed ductwork for this project?

$1,227,250

Explanation:

Calculation for the total cost of the installed ductwork for this project

First step is to calculate the costs that have to be estimated based on unit technique for both material and insulation

Material: 7,500ft*15 lb/ft*$8.5/lb=$956,250

Insulation: 7,500ft *$10/ft=$75,000

The next step is to calculate for the Total cost

Engineering design cost $16,000,

Labor $180,000

Material $956,250

Insulation $75,000

Total cost $1,227,250

Therefore the Total cost of the installed ductwork for this project will be $1,227,250
