BACKGROUND The project replaced the eastbound to northbound off ramp "loop" connection and the direct eastbound to southbound connection with a "T" style signalized intersection at Foothill Road just south of the 1-580 interchange. These changes were made to improve interchange safety, traffic flow, and bicycle and pedestrian access. Improvements consisted of the removal of the eastbound to northbound loop ramp, realigning the eastbound diagonal on and off ramp, constructing a signalized intersection at 1-580 and Foothill Road just south of 1-580 interchange, widening Foothill Road to accommodate dual right turn lanes at the eastbound on ramp, and providing bike lanes on Foothill Road in both directions. Improvements also included a retaining wall along the 1-580 eastbound off ramp, roadway paving, modification of the existing storm drain system, installation of an irrigation system for planting and landscaping, and signing and striping of the roadway. On August 20, 2013, Council awarded the contract to the lowest responsible bidder, Ghilotti Construction Company, Inc. in the amount of $5,300,625.90 and authorized the Director of Community Development to approve and execute contract change orders for a contingency amount not to exceed $535,600. On August 20, 2013, Council approved the Sixth Amendment to the Professional Services Agreement with T.Y. Lin International in the amount of$89,224 to provide design services during construction and approved the Professional Services Agreement with Carlson Management Inc. in the amount of $411,582.85 for the construction management services for the I-580/Foothill Road Interchange Improvement project. On July 15, 2014, Council approved Amendment No.1 to the Professional Services Agreement with Carlson Management, Inc. to provide additional construction management services in the amount of $87,000, for a total of$498,583. The City issued a task authorization for$45,366 for Ruggeri Jensen Azar under the City's on call survey contract to perform construction staking and surveying for the project. DISCUSSION The final construction contract cost is $5,613,724 which includes $331,099 (5.90% of the construction contract) in change orders. The contract change orders were the result of an increase in contract quantities and additional work performed by the contractor. Staff recommends $30,000 be retained to cover the cost of tree/landscaping/irrigation restoration at Residence Inn. Existing trees on the Residence Inn property were removed as necessary during the construction of the retaining wall along the 1-580 eastbound off- ramp adjacent to Residence Inn. Staff is currently working with the property owner for the reimbursement of the cost for restoration, which is being completed by the property owner. The project funding included a Congestion Management and Air Quality (CMAQ) grant for$709,000 for which the City has been reimbursed $645,099. Staff will prepare a Project Completion Expenditure Report to Caltrans for reimbursement for the remaining CMAQ funding amount of$63,901. The final project funding and expenditures are summarized in Attachment 1 to this report, indicating total project expenses of$6,897,941 and a balance of$69,296 remaining in the CIP budget. All of the work has been completed to the City's satisfaction. Staff Page 2 of 3
