Retrofitting needs of each bridge vary. Some require relatively minor retrofitting such as sealing cracks that are becoming large enough to compromise the integrity of the bridges; other retrofitting needs include reinforcing structural bridge supports to prevent collapse in the event of seismic events. At the time the bridges were initially evaluated (late 1990s), Caltrans did not require local agencies to complete the environmental process prior to beginning seismic retrofit work. However, Caltrans' regulations have since changed, and that Agency is now requiring completion of all environmental processing and permitting with numerous federal and state agencies before any retrofitting may occur. In light of the stricter environmental processing requirements City staff recommends the retention of TY LIN International Consulting to provide all necessary support services to begin the retrofitting of the eight bridges identified to need retrofitting and eligible for such repair under Caltrans' Seismic Safety Retrofit Program. To allow the project to begin the needed environmental process as soon as possible the City requests that the needed services be awarded to TY LIN per the purchasing ordinance section 3.08.140 (c), which allows the City to piggyback on the completed bid process by another agency. The City of Grand Terrace completed an informal bidding procedure in accordance to the purchasing ordinance section 3.08.070 (b) for similar professional firms able to provide `Seismic Retrofit Project Management Services.' The City of Grand Terrace received five bids and found the consultant that best served the interests of its City in providing seismic retrofit project management services was TY LIN. Services that TY LIN International will provide include authoring of a status update, summarizing work completed to date, level of permitting and approvals achieved, funding status with Caltrans, and other pertinent data. TY LIN will assist with the securing of resource agency and railroad company permits as needed. Furthermore, the fine will complete Preliminary Environmental Survey (PES) forms for each bridge and submit them to Caltrans for review, comment and final sign off. City staff will be responsible for obtaining updated structural plans from the firms originally retained by the City for retrofitting in the 1990s. Once these plans have been updated and submitted to the City, TY LIN will be responsible for the preparation of non-structural plans for the bridges, including preparation of traffic handling plans and traffic control requirements; the firm will also prepare necessary plans and specifications for inclusion in the bid packet. In light of the amount of research and environmental processing involved in the seismic retrofitting requirements of the City's bridges, TY LIN is qualified to handle the scope of work required. The firm has demonstrated competence and success in similar retrofitting projects for various municipalities, and their rates are competitive to industry standards. FINANCIAL IMPACT: Due to the new Caltrans environmental processing requirements staff recommends redistributing available funds used to budget the La Cadena Bridge Project in account number 450-0611-6910-
