INTRODUCTION
The enclosed resolution authorize the initiation of the public bidding procedure for the
Carnegie -Stout Library Roofs 1 & 2 Restoration Project.
BACKGROUND
The current roofs 1 & 2 on the central and east side of the building are 19 years old and
currently showing signs of noticeable deterioration. In 2020 diagnostic testing and analysis
was completed on both sections of the roof to determine the remaining service life. The
results of the analysis indicated there were a few areas where the roof membrane was
leaking, and the insulation board was wet from water. A maintenance repair project was
completed to address the active leak areas to avoid any potential damage inside the
building. The east roof was replaced in 2010 as part of the previous library major renovation
project and remains under warranty and is in good condition.
DISCUSSION
The 2020 analysis also recommended installing a new monolithic urethane liquid applied
fully reinforced restoration of not less than 80mils with a 20-year warranty. In order to
ensure the long-term viability of the building and to eliminate the potential for water damage
the Engineering Department is recommending proceeding with this restoration project.
As part of the competitive bidding process the specifications use Tremco Roofing Inc.'s
AlphaGradeTm Restoration System as the basis of design. Prospective bidders will list the
quantity of materials they will need to complete the work, which the City will subsequently
direct purchase these goods and turn them over to the contractor off of a cooperative
purchasing contract from AEPA — the Association of Educational Purchasing Agencies.
Using the cooperative purchasing contract is estimated to save the project 10%-15% on the
price of materials. The estimated cost of the goods to be purchased for this project is
$79,000. Bidders will also directly list on their bid form along with the quantities to be used
on the project, the cost of labor and installation. The combined total cost of labor and
installation plus calculating the unit price cost of materials will be used to establish the low

bidder for the project. If a bidder prefers not to use the AlphaGradeTm Restoration System
they may submit a substitution request for approval to use an alternative, equivalent product
as is regularly done on all types of public improvement projects.
