6.//I-~ The rubber is more expensive in the construction process. However, there is cost avoidance to the City in not performing the root cutting per site and the not performing the necessary revisions to the title documents creating the sidewalk maintenance easements which require expensive title searches and deed revisions, and time consuming notarization. The trees will experience less root disturbance with the rubber sidewalk installation than root cutting and concrete installation and this is better for the trees. Change Order No.2, in the amount of $56,000 will incorporate the use of rubber sidewalks at locations that are not recommended for root pruning due to the tree's condition or species of tree present or where easements cannot be secured to allow adequate space for root cutting. Previously, staff used asphalt in these applications. There are approximately 29 sites on Ohio Avenue of 50 total tree sites where root pruning will not be performed on Evergreen Chinese Elms for tree preservation. JJR Construction has been certified as an installer by the rubber sidewalk manufacturer. Their unit price has been negotiated for the intended work. Chanqe Order No.3: Prior to JJR Construction beginning the pre-determined Tree Preservation and Sidewalk Repair Program, the City experienced delays in the Cost Shared Sidewalk Repair Project due to the contractor defaulting on the project. The City subsequently annulled the contract and awarded the remaining work to the second lowest bidder. There was a substantial delay between the annulment of the contract, the award to the second lowest bidder, and the second bidder's ability to begin the work. In the interim delay period, JJR Construction agreed to assist the City by completing property owner-paid locations at the Tree "reservation and Sidewalk Repair Program contract unit prices. JJR Construction's v. 'ingness to complete these committed but unfinished sites allowed previously paid cost shared repairs to be completed up to 90 days earlier than would have otherwise occurred. Change order No.3 to the Tree Preservation and Sidewalk Repair Contract is in the amount of $142,413.00 and includes $112,027.50 of cost shared repair sites completed by JJR Construction prior to beginning the Tree Preservation and Sidewalk Repair Program. This change order will facilitate completion of the originally planned project within the neighborhood bordered by Massachusetts, Woodside Road, and Alameda de las Pulgas. The approval of Change Order No.3 is within the 25% Change Order amount allowed by the project specifications. JJR Construction has agreed to perform the additional work at the existing contract unit prices. In summary, the Council has previously approved the scope of work included in Change Order No.3, as well as the budget to support the work. While no additiona funds are being spent, JJR's contract cap must be increased by the Council so that staff can now give direction to complete the unfinished portion of the Tree Preservation and Sidewalk Repair Program.
