Cash Contract No. S.S. 628 Brookshire Ave Pavement RehabAPPROVED BY CITY MANAGER AGENDA MEMO TO: Mayor and Members of the City Council FROM: Office of the City Manager By: John Oskoui, P.E., Director of Public Works DATE: July 24, 2012 SUBJECT: CASH CONTRACT NO. S.S. 628 BROOKSHIRE AVENUE PAVEMENT REHABILITATION PROJECT - APPROVE PLANS AND SPECIFICATIONS AND AUTHORIZE SOLICITATION FOR BIDS RECOMMENDATION: That the City Council approve the plans and specifications and authorize solicitation for bids for Cash Contract No. S.S. 628 — Brookshire Avenue Pavement Rehabilitation Project. BACKGROUND: The City's Pavement Management Information System (PMIS) is the primary tool used to prioritize street pavement rehabilitation projects throughout the City. Based on a review of the PMIS, Brookshire Avenue is a Secondary Arterial street requiring rehabilitation of its existing pavement, which has deteriorated to a state of disrepair that cannot be handled through routine street maintenance (i.e. pothole patching, crack sealing, and slurry sealing). Specifically, Brookshire Avenue has extensive longitudinal and transverse cracking and numerous patches due to pavement repair and utility work. Therefore, it is recommended that the existing pavement on Brookshire Avenue between Imperial Highway and Davis Street undergo comprehensive rehabilitation to bring it to an acceptable standard. DISCUSSION: The Engineering Division staff has completed preparation of the plans, specifications and construction cost estimate for Cash Contract No. S.S. 628 — Brookshire Avenue Pavement Rehabilitation Project, which is now ready for solicitation of construction bids. This project consists of the rehabilitation of the existing pavement for the entire length of the project with the exception of the segment between Boyne Street and Davis Street, which will involve full pavement reconstruction. In addition, the project will include the miscellaneous repair of concrete surfaces (i.e., curb and gutter, sidewalk, driveway approaches, curb ramps), adjusting of manholes, valve covers and survey monuments to grade and incidental replacement of traffic signal loop detectors, striping and pavement markings. The work will also include potable water improvements such as upgrades to fire hydrants as well as lateral and main service lines, meters, and connections. The attached list of work items may be referenced for a detailed scope of work. The project covers approximately 1.25 miles of roadway. The project limits are shown on the attached project Location Map.
