RECOMMENDATION: That the Board of Public Utilities approve an increase in the capital expenditure for Work Order No.1121193 from $721,545.45 to $945,462.24. BACKGROUND: On January 18, 2013, the Board of Public Utilities approved Work Order No. 1121193 in the amount of $721,545.45.The project consisted of the structural rehabilitation of four deteriorated vaults(V2805,V28381 V2840 and V2909), replacement of associated equipment, and the conversion of two existing pull boxes (X7024 and X10612) on Chicago Avenue between Spruce Street and Marlborough Avenue. Public Works Department staff determined that the project would need to be completed during restricted hours to avoid an undesirable public impact.The project site is near the on-going grade separation project at Iowa Avenue and Citrus Street and is part of the designated traffic detour route.Work hours were restricted to minimize the impact to traffic that was already being affected by the grade separation project. Description Planned Schedule Actual Schedule Engineering by RPU Staff and Consultant Start 8/3/12 8/3/12 Duration 6 Weeks 6 Weeks Civil Work performed by Contractor Start 11/5/12 3/11/13 Duration 8 Weeks 14 Weeks Electrical work performed by RPU Field Forces Start 2/12/13 4/29/13 Duration J 6 Weeks 12 Weeks The Notice to Proceed for the civil work was issued on February 21, 2013, but work was delayed until switching to de-energize circuits in the first two vaults was completed. There were six weeks of additional delays due to scheduling railroad company flagmen at one structure and waiting for Riverside Public Utilities (RPU) forces to complete electrical work at the first two structures before re-mobilizing to continue with the work on the second two vaults.An initial change order amount of$25,451.59 was approved due to changed conditions caused by other utilities where actual locations did not match as-built locations provided.
