DISCUSSION
The Fiscal Year 2018-19 Capital Improvement Plan provides for roofing repairs and a full
roof restoration at the Arcadia Library. The current roof system was installed during the
building reconstruction in 1996 and was failing in numerous areas. The existing top layer
roof cap sheet was deteriorating and had begun to bubble and develop “mole runs”, which
resulted in cracking, seam separation, and leaks. Additionally, the base flashings and cap
sheets were starting to pull away from the parapet walls creating open gaps for water to
infiltrate the building. During the recent rains, extensive leaking occurred that could have
potentially ruined books and computer equipment. Multiple spot repairs have been
completed to extend the life of this roof, but a more extensive restoration was necessary
to ensure that the building did not encounter costly water damage during heavy rains.

On May 7, 2019, the City Council approved a contract with Western States Roofing, Inc.
for the Library Roof Restoration Project. The work performed included repairs to all
imperfections in the roof system such as blisters, mole runs, splits, and tears with a three-
course application of mesh and mastic. The roof was then top-coated with Garland brand
“White Star” polyurea coating and 3/8-inch gravel.
Consequently, the project generated odors inside the library building that resulted in
closing the Library for 4 days. In an effort to mitigate the odor related disruption to library
operations, work was conducted on weekends. The three change orders listed below
were due to overtime incurred for work performed on four weekend dates.
CCO# Description Amount
1. Added overtime installation labor on 8/11/2019 $2,316.91
2. Added overtime installation labor on 8/18/2019 $2,316.91
3. Added overtime installation labor on 8/31/2019 and
9/1/2019 $4,162.89
Total: $8,796.71
The change orders increased the overall contract amount by $8,796.71, or 2.19% more
than the original contract amount. All other terms and conditions of this contract have
been complied with and the work has been performed to the satisfaction of the Project
Manager. Western States Roofing, Inc. has completed the work as defined in the project
plans and specifications in an efficient and timely manner.

Funds in the amount of $685,000 for both labor and materials have been budgeted in the
