DISCUSSION The Bridge Improvements at Various Locations Project, CIP No. 16514 — Fed ID 5101(029), performed routine preventative maintenance that included various repairs, such as concrete spall and crack repairs and joint seal replacements, at Case Avenue Bridge at Mission Creek, Laurel Creek Drive Bridge at Laurel Creek, West Las Positas Boulevard Bridge at G-3 Channel, and Owens Drive Bridge at Chabot Channel. In addition, the project included major maintenance at the Santa Rita Road Bridge at Arroyo Mocho which included installation of concrete approach slabs, deck sealing and water line work to address the settlement occurring at the approaches of the bridge. The project construction proved very challenging, requiring additional funding to address several unforeseen conditions. In the end, there were 12 change orders for a total of $263,351, including the balancing change order, negotiated by the Director of Engineering to address issues discovered during construction that were unforeseen at the time of project design. Attachment 2 is a list of the change orders. Consultant Support In addition to the construction contractor, various consultant services were required on the project, both during design and construction. Biggs Cardosa and Associates, Inc. provided design and construction support services for review of project submittals, RFIs and review field conditions. Geocon, Inc., through the City's on-call professional services agreement for geotechnical services, provided material testing and soil density and compaction testing, abiding by the City's Quality Assurance Program. Pakpour Consulting, Inc., through the City's on-call professional services agreement for general civil engineering, provided engineering support services, reviewed the project documents and updated the City's procurement documents for consulting support services for federal funded projects, utilized for procuring TRC's services. TRC Engineers, Inc., through a professional services agreement, performed on-site inspection and resident engineering services for the project. TRC provided a full-time inspector to oversee the daily work. In addition, TRC provided a part-time resident engineer to complete, review, and approve for submittal, all the required Caltrans documents. The change orders on the project added over a month of on-site work, plus a higher than anticipated amount of Caltrans paperwork to the project. Working with City staff to supplement where possible, TRC was still unable to complete the work within the original estimated hours. Staff recommends approving Amendment No. 1 to the contract for $31,700 to cover the additional inspection and resident engineering services required. Project Costs and Funding Sources The total project cost, including design, the construction contract, all change orders, and consultant services was $2,008,685, with a total funding of$2,044,763 as summarized in Attachment 1. Funding is primarily comprised of reimbursable federal grant funds that cover 88.53 percent of eligible expenditures with a 11.47 percent local share. The Page 5 of 6
