Provide a parametric cost estimate for the parking structure (from your project) using the following information (assume the parking deck is post tensioned) a. Post tensioned Concrete parking deck built 6 years ago cost $5,250,000 and had 150,000 sf floor space b. Concrete warehouse built 2 years ago cost $1,680,000 and had 80,000 sf floor space c. Non post tensioned concrete parking deck built 1 year ago cost $5,400,000 and had 200,000 sf floor space d. Post tensioned Concrete parking deck built 8 years ago cost $6,250,000 and had 170,000 sf floor space

Total Cost per square footage = $ 119.76

Explanation:

As each of these costs is related to the area and building the cost driver would be area square footage floor space.

We divide the cost with the cost driver to get the parametric cost estimate for each of the following.

a. Concrete parking deck cost $5,250,000 / 150,000 sf floor space=$35 per sf floor space

b. Concrete warehouse cost $1,680,000 / 80,000 sf floor space = 21 per sf floor space

c. Non post tensioned concrete parking deck cost $5,400,000 / 200,000 sf floor space = 27 per sf floor space

d. Post tensioned Concrete parking deck cost $6,250,000 / 170,000 sf floor space = 36.76 per sf floor space

Total Cost per square footage = $35 + $21 + $27 + $36.76 = $ 119.76
