Background The City's comprehensive sidewalk maintenance program includes two sidewalk repair projects performed by contractors: . The Tree Preservation and Sidewalk Repair Program (subject project) completes block by block sidewalk repairs in a pre-determined project area at no cost to the adjacent property owner for offsets of one-inch or greater. Offsets less than one- inch may be repaired through a 50% cost shared agreement with the property owner. . 1 1e Cost Shared Sidewalk Repair Project completes repairs to sidewalk offsets Ie ated outside of the pre-determined project area through a 50% cost shared agreement with the property owner. On June 7, 2004, the City Council approved the contract documents and specifications for the Tree Preservation and Sidewalk Repair Program and awarded the contract to JJR Construction, Inc. for the amount of $569,652.00. JJR Construction has been performing the sidewalk repairs to the contract specifications and to the satisfaction of staff. Change Order No.1 adjusted quantities and did not change the approved contract amount. As of July 18, 2005, approved progress payments total approximately $498,000, and staff estimates that the full contract amount will be reached by the second week of August. Therefore, staff is seeking Council authority as follows: Chanqe Order No.2: During the project, staff developed an alternative to concrete using recycled rubber sidewalks. Five test sections were approved by the City Engineer on Bristol Way. The sites were completed by JJR Construction to the manufacturer's specifications. The use of the recycled n..bber materials results in reduced root cutting. The material is thinner and more flexible than concrete and doesn't require as deep or complete base excavation. The base material used under the rubber panels is decomposed granite (DG) which can be compacted around existing roots. The rubber material can be placed over the top of the roots and DG without the need for extensive root cutting. If the site needs re-visiting in the future, the rubber panels can be pulled up, site corrections made, and the rubber panels can be re-used. 03-04 TPSRP change order Page 1 of 3
