Approve the Cost Analysis for a total estimated project delivery cost of $2,071,602. <br />DISCUSSION <br />The existing 10 -inch diameter cast iron water main on 17th Street was installed in the 1930's and <br />has begun to experience a number of breaks and leaks. Staff monitors the condition of water main <br />pipelines by assessing critical factors such as age, history of breaks, size, location, and system <br />redundancy to determine the priority of replacement needs. Based on an analysis of these factors, <br />the water main on 17th Street between Bristol Street and Broadway has been identified as the <br />highest priority for replacement due to its high probability of failure and significant consequences <br />should a failure occur. <br />Prior to advertising the project for bids, staff considered the impacts of construction on businesses <br />and regional traffic. A vicinity map in Exhibit 1 shows the relative location of the water main on 17`h <br />Street to other major city streets. As a result, the project scope was developed to include the <br />option and flexibility to perform construction during nighttime hours as a base bid, along with the <br />option to perform the work during standard daytime hours. <br />Staff recommends that the contract be awarded based on nighttime work. If nighttime work is <br />performed, all vehicle travel lanes would be open during the daytime, allowing access to <br />businesses, and would not interfere with critical peak morning and evening commutes. Working <br />hours for the construction would be 7:00 p.m. to 5:00 a.m. Nighttime construction would adhere to <br />the City's noise ordinance at all times; nonetheless, staff will require that noisier construction <br />activities be limited to before 10:00 p.m. <br />23A -1 <br />
