SUBJECT:ROOF REPLACEMENT AT THE ELECTRIC POWER PLANT
PROJECT COMPLETION
COUNCIL ACTION FORM
BACKGROUND:
The Power Plant contains several separate roof sections. Several of the Power Plant roofs
were previously identified by a consultant as needing to be replaced. Leaking roofs have the
potential to create safety hazards and cause issues with operations.
This project replaced approximately 18,840 sq. ft. of existing built-up roofing on three
separate roof areas and levels, which is approximately half of the total roof square
footage at the Power Plant. New roof drains and portions of metal decking were also
replaced. The new roof system is designed to provide an effective service life of at least
20 years.
On February 27, 2024, City Council awarded a contract to Central States Roofing of Ames, IA,
for the Roof Replacement at the Power Plant. The bid included a unit price to replace any
additional deteriorated decking discovered when performing the original scope. The original
amount of the contract was $1,591,000. There were three change orders during the project:
Change Order No. 1, in the amount of $20,000, was approved by staff to address
additional failed decking found shortly after replacement work began.
Change Order No. 2, in the amount of $100,000, was approved by City Council on May
14, 2024 to continue replacing deteriorated decking material that was encountered.
Change Order No. 3, in the amount of $13,540, was approved by staff to replace wall
damage identified during the project, bringing the final contractual amount to $1,724,540.
Total budgeted funds for this project equaled $2,091,247.
The project has now been completed in accordance with the approved plans and
specifications. The project engineer has issued a certificate of completion.

Roofing, of Ames, IA, in the amount of $1,724,540 (inclusive of sales tax) and release
