MEMORANDUM Kevin O'Rourke To: Interim City Manager Date: May 16, 2013 Raul Godinez II, Executive Director From: Public Works Agency Project Nos. 11 -6736 & 11 -6746 Broadway Rehabilitation: Anahurst PI. to First St. Subject: Change Order No. 4 Contractor: All American Asphalt PO BOX 2229 Corona, CA 92878 Project Description: Broadway Rehabilitation from Anahurst Place to First Street Change Order Number: 4 Accounting Unit - Account - Activity Number: JUSTIFICATION Change Order Total: $ 242,212.00 03017660 - 11673'601028 The streetlight portion of this project requires the contractor to separate the high voltage streetlights along Broadway from the existing high voltage system on Russell Avenue just east of Birch Street (see Exhibit 1a). The work includes removing the single high voltage (5,000 volts) wire from the existing conduit, installing three new wires into the existing conduit, installing new metal halide fixtures, and installing conduit and wire to an existing 240V service pedestal located on Borchard Avenue one block west of Broadway. When the contractor was performing the Broadway streetlight work on Russell Avenue, it was discovered that the streetlights were interconnected with the adjacent street, which is not consistent with the as- builts (see Exhibit 1a). Similar conditions were found on the streetlights on Wilshire Avenue and on Borchard Avenue (see Exhibit 1b). Essentially, the existing streetlight system is a continuous loop and separating the system was not in the original contract. Therefore, the planned streetlight work needed to be expanded. A prior approval for this work was granted 3/13/2012. The initial scope of extra work included all of the streetlights on Ross Street and Birch Street between McFadden Avenue and Edinger Avenue at a cost of $162,989. However, while performing the extra work, the conduits were found severely deteriorated and damaged beyond repair by corrosion and tree roots, necessitating replacement at an added cost of $81,223. Therefore the total cost of the streetlight upgrades is $242,212. AGREED COST $ 242,212.00
