Ready, City Manager Initiated by: Public Works and Engineering Department SUMMARY Approval of Contract Change Order No. 1 to Agreement No. 6093 with PTM General Engineering Services is necessary to accommodate required changes in the work related to the Indian Canyon Drive at Vista Chino Traffic Signal Modification, City Project No. 08-17. RECOMMENDATION: 1) Approve Change Order No. 1 to Agreement No. 6093 with PTM General Engineering Services, in an amount of $27,354.83 for a revised total contract amount of $230,557.83 for the Indian Canyon Drive at Vista Chino Traffic Signal Modification, City Project No. 08-17; and 2) Authorize the City Manager to execute all necessary documents. STAFF ANALYSIS: On November 17, 2010, the City Council awarded a contract to PTM General Engineering Services for modification and upgrade of the existing traffic signal at the Indian Canyon Drive and Vista Chino intersection. Previously, the existing traffic signal had no left-turn phasing in any direction, which made turning left difficult during peak hours of traffic at this highly congested intersection. Vista Chino is also State Highway 111, and Caltrans operates and maintains this traffic signal. Construction of this project has been under inspection by Caltrans, and during construction Caltrans imposed certain requirements related to installation of underground conduit and trench pavement repairs. These additional requirements were not originally included in the project, and complying with these requirements incurred additional cost to the contractor. Item No. 2A . City Council Staff Report September 21, 2011 - Page 2 Contract Change Order No. 1 to CP 08-17 Staff has negotiated the cost to comply with the Caltrans requirements, and recommends Council approve Contract Change Order No. 1 to compensate the contractor for the work completed pursuant to Caltrans requirements. FISCAL IMPACT: Sufficient funds are available in Local Measure A account 134-4498-50271. No local miscellaneous General Funds are being used for this project.

In accordance with State of California Requirements,the conduit trenches will be ground 18" outside of trench edges and final paving cap will be placed.
