Are Contractors Ripping Off Georgetown?

Georgetown is preparing to entertain bids for a new fire station on Williams Drive near FM3405. The City has budgeted $5M for the construction of the building.

That estimate does not include the land which is being furnished by ESD#8.

The two story fire station with community room is 11,125 square feet in size.

Using an on-line construction cost estimator gives the following result:

Notice this estimate assumes construction in the Austin area using the "high" cost index.

We see the costs should be about $2.1M. Adding a 10% architect fee would only increase the costs to about $2.3M.

The City is estimating costs to be about $425/sf while the estimator indicates the costs should be about $190/sf.

Why is the City budgeting $5M for a $2.1M-$2.3M fire station?

So, what is going on? Is the City getting ripped off?
