A $10,000 \text{ m}^2$ warehouse was constructed in 2010 for a total cost of \1,500,000$. The Engineering News-Record (ENR) Building Cost Index at the time of construction in 2010 was$4500$. The current ENR index for the year 2024 is$8100$.

Estimate the conceptual budget required to build the identical warehouse today in the same location.

An engineering firm designed and built a $50 \text{ MGD}$ (Million Gallons per Day) water treatment plant for \40,000,000$. They are asked by a different municipality to provide a conceptual estimate for a much larger,$80 \text$ plant of the same technology.

Historical data suggests the capacity scaling exponent ($X$) for this specific type of water treatment plant is $0.70$. Determine the conceptual budget for the new plant.

A structural steel warehouse was constructed in Chicago, IL in 2018 for a total cost of \3,500,000$. An estimator needs to provide a conceptual budget for building the exact same warehouse in Denver, CO in 2024.

Historical Data available:

• 2018 National Average Index: $100$

• 2024 National Average Index: $135$

• Chicago City Cost Index (CCI): $115$ (relative to a national average of $100$)

• Denver City Cost Index (CCI): $108$ (relative to a national average of $100$)

A developer wants to build a new $45,000 \text{ sq ft}$ medical office building. They do not have architectural drawings yet. The estimating firm looks at their database of the last five medical office buildings they constructed in the same region over the past two years:

• Project A: $30,000 \text{ sq ft}$, \8,100,000$

• Project B: $50,000 \text{ sq ft}$, \14,500,000$

• Project C: $25,000 \text{ sq ft}$, \6,500,000$

Determine the average historical cost per square foot, and use it to estimate the developer's new project.
