HomeMy WebLinkAbout11 Spring Street Pipeline Project Agenda Item # 11 Public Utility District ACTION To: Board of Directors From: Neil Kaufman Date: April 16, 2014 Subject: Consideration of Setting Contract Parameters for the Spring Street Pipeline Rehabilitation Project 1. WHY THIS MATTER IS BEFORE THE BOARD Board approval is required for expenditures in excess of$15,000. 2. HISTORY The Water Department has an ongoing need to replace existing water pipelines that fall into two basic categories. 1) Pipes that are in poor condition and require repeated repairs. 2) Pipes that are old, undersized (typically 4-inch diameter and smaller) and have exceeded their useful life. The Town of Truckee will be conducting a streetscape project in the Brickeltown area of Truckee. The area of the Town's project is from 10120 Jibboom Street to the traffic roundabout at the McIver Crossing. The existing water pipe in Spring Street between Jibboom Street and Keiser Avenue is in poor condition and the Water Department would like to address this problem before the final paving and parking improvements are constructed along Spring Street. A workshop regarding this project was held on April 2, 2014. 3. NEW INFORMATION The bid documents for the project have been completed and the District has begun advertising for bids. A copy of the bid documents in PDF format is included as Attachment 1. The Town's streetscape project is scheduled to begin construction on July 2014. Therefore, it is necessary for the District to complete its work in June in order to avoid conflicts between two separate contractors working in a limited area. The current project schedule is: • Begin Advertising for Bids -April 2014 • Bid Opening - May 2014 • Bid Award - May 2014 • Construction - June 2014 • Project Completion - June 2014 In order to perform the construction in June, it is necessary to award the contract in early May. This time frame provides a few weeks for the contractor to submit all the necessary contractual requirements such as bonds and insurance and to order materials. As discussed at the April 2 workshop, the next scheduled Board meeting on May 21 does not fit well with the need to award the project in early May. It was suggested that the Board could consider authorizing the award of the contract up to a certain dollar value prior to the actual bid opening. After the bid opening, if the apparent low bid exceeds the authorized dollar value, or if some irregularity occurs, it would be necessary for the Board to take additional action, possibly at a special meeting. The estimated construction cost for the project is $60,000. 4. FISCAL IMPACT The estimated cost for the project is $60,000. The planned funding source for this project is the Water Department Capital Replacement Fund. 5. RECOMMENDATION a) Authorize the award of the Spring Street Pipeline Rehabilitation construction contract to the lowest responsive and responsible bidder in for an amount not to exceed $60,000. b) Establish a 10 percent change or allowance in an amount not exceed $6,000. c) Authorize the transfer of up $66,000 from the Water Department Capital Replacement Fund to the Water Department General Fund.
