McGuire, ngineer III Wt.1�IV� i� UTIL DIR BU L(i lalHR DIR SUBJECT: MISSION PLAZA BANK WALKWAY WALL, SPECIFICATION No. 99257 ye CAO CAO RECOMMENDATION 1. Award the contract for the"Mission Plaza Bank Walkway Wall", Specification No. 99257, to Rehak Construction in the total project bid amount of$120,000. 2. Authorize the transfer of$55,000 from the CII' Reserve Account to the project account for funding of the Contract and maintaining 10% construction contingency. DISCUSSION Over the years, the steep creek bank below the Amphitheater and the Murray Adobe in Mission Plaza has been subjected to soil erosion in large rain events. This has caused-soil to spill onto the existing paved walkway, creating a maintenance problem and continued erosion of the creek bank. This erosion has resulted in tree root exposure, potentially weakening the stability of the trees, and a reduction in distance between the top of the bank and the Murray Adobe.. In 1997 a project to reinforce the bank was approved as part of the 1997-99 Financial Plan. At that time the project included the replacement of the bricks on the Warden Bridge and adjacent walkways. Due to funding limitations and issues with accessibility conditions on the bridge, the brick work portion of the project was eliminated. The project design and construction has been continually pushed back through a combination of substantial design changes, higher priority capital improvement projects and permitting problems. The current project is designed to prevent soil erosion from the bank by reinforcing the base of the slope with a 3 -4 foot high segmental concrete block retaining wall along approximately 225 feet of the walkway. The existing benches will be refurbished and a new bench installed to replace one lost to flooding. Trash receptacles will be replaced and relocated to provide more clearance along the walkway. Existing lighting will be replaced with in-wall light fixtures. Native plants will be used to re-vegetate the construction area. On June 19, 2006, the CAO authorized staff to advertise the project for bids. On July 20, 2006, bids were opened. The City received four bids with all bids exceeding the Engineer's Estimate for construction. The lowest project bid was from JPG Construction, Inc. in the amount of $82,250. Two days later, JPG Construction withdrew their bid proposal, stating a significant clerical-error had been made. The next low bid was from Rehak Construction of Monterey, California in the amount of $120,000. This bid is approximately 71%. over the Engineer's Estimate of$70,000, due to the labor costs associated with transporting construction materials to the site that has no vehicle access; the tight confines of the construction site itself, requiring specialized equipment or hand labor and the rising costs of construction materials. Staff is Mission Plaza Bank Walkway Wall Page 2 requesting award of the contract by the City Council due to the need to provide additional funds to the project from the CIP Reserve account. FISCAL IMPACT This project was approved as part of Cultural Services, in the 1997-99 Financial Plan, Appendix B Capital Improvement Plan, page 176 and estimated to cost$85,000. Staff is recommending use of CIP reserve to complete the necessary funding for the project. Currently, there is $109,000 available in the CIP Reserve Account to support this use. Project Costs Construction $120,000 Construction Contingency(10%) 12,000 Printing&Advertising 1,000 Materials Testing& Inspection 2,000 Miscellaneous Costs 1,000 Total Cost: $1367000 Project Funding Remaining Original Budget $81,000 Additional Funding(from CIP Reserve Account) 55,000 Total: $136,000 ALTERNATIVES 1. Reject all bids and re-bid the project Labor, fuel and construction material costs continue to rise. Re-bidding the project would likely result in an even more expensive project. Also; due to the Department of Fish & Game's permit restriction on when construction can proceed, this project would have to be built in 2007 and an extension fee paid. 2. Defer the project Currently, there are areas along the bank that are susceptible to erosion in a significant storm event. If the wall is not installed, erosion will continue and potentially result in structural damage to the Murray Adobe or the pedestrian bridge above the creek bank. ATTACHMENTS Attachment 1.
