The City, through its design consultant TLCD Architects, requested detailed cost estimates for each of the three concept design options. In addition, the City requested a cost estimate for an alternative approach that would demolish the existing structure and construct a parking lot with no other improvements. TLCD retained the services of Cromb Associates Construction Cost Management to provide the cost estimating.
In preparing the cost estimates, Cromb incorporated several components to ensure the estimates are as comprehensive and accurate as possible in this stage of design, including:
Demolition and site work
Footings and foundations, including an allowance for potential seismic issues
Superstructure, exterior closure, roofing, and interior construction
Mechanical and electrical
Equipment (fixtures and furnishings)
Professional services (design and construction administration)
Contractor general conditions, overhead, bonds/insurance, and profit
Contingency (15% of total construction costs)
Below are the total cost estimates for each option. Detailed cost estimates (44 pages) can be downloaded from the link above.
