FOR THE LIBRARY ROOF RESTORATION PROJECT AS COMPLETE Recommendation: Approve SUMMARY On May 7, 2019, the City Council approved a contract with Western States Roofing, Inc. in the amount of $401,400 for the Library Roof Restoration Project. The terms and conditions of this project have been complied with and the work has been performed to the satisfaction of the Project Manager for a total project cost of $410,196.71. This amount reflects the original contract amount of $401,400 plus contract change orders totaling $8,796.71, or 2.19%, more than the original contract amount. It is recommended that the City Council accept all work performed by Western States Roofing Inc. for the Library Roof Restoration Project as complete, and authorize the final payment to be made in accordance with the contract documents, subject to the retention of $20,509.84. 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. Accept Library Roof Restoration Project October 15, 2019 Page 2 of 3 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. FISCAL IMPACT Funds in the amount of $685,000 for both labor and materials have been budgeted in the Fiscal Year 2018-19 Capital Improvement Plan for the Library Roof Restoration Project. On May 7, 2019, the City Council separately approved the purchase of the roofing materials from the Garland Company, Inc. for $240,840.56. The cost for roof restoration and repair services was $410,196.71, for a total project cost of $651,037.27.
