Page 3 of 5 intersection with Owens Drive. To do so, related modifications include adding a second northbound left-turn lane and eliminating the northbound free right-turn lane on the south side of the Hopyard Road/Owens Drive intersection. This project also includes adding a southbound bike lane to close the existing bike lane gap from the I-580 eastbound off-ramp intersection to 180 feet south of Owens Drive. The work includes new sidewalks, medians, landscaping, traffic signals, soundwalls, and repaving of the area. The project initially started with a simple design scope for adding a dedicated southbound right-turn lane at the Hopyard Road and Owens Drive intersection; extensive bike and pedestrian improvements were not part of the original design scope. During the preliminary plan review process, Caltrans conditioned additional bike and pedestrian improvements, which extended the project limit and necessitated modifications to the existing median and landscaping. When the project was submitted to Caltrans for encroachment permit approval, Caltrans implemented its new Design Engineering Evaluation Report (DEER) process for project approval. The DEER required additional design modifications, engineering study, and analysis related to the project, which were not anticipated at the start of the project. The City requested Caltrans to waive the DEER review process for encroachment permit approval, and Caltrans declined to grant any exception to its requirements. Multiple rounds of review, design modifications, and various requirements from Caltrans impacted the project approval timeline. Due to the construction staging and the necessity of maintaining traffic through the intersection, daytime work has limited hours. It is anticipated the majority of work will take place at night when additional lanes of traffic can be closed to accommodate construction activities. Bids Sealed bids for this project were opened on March 20, 2024. Three bids were submitted, ranging from $4,183,298 to $4,903,100. The low bid amount, submitted by Bay Cities Paving & Grading, Inc., in the amount of $4,183,298 is approximately 10 percent higher than the Engineer's Estimate of $3,815,876 (see Attachment 1). Staff reviewed bids and found the low bid responsive and responsible. Past work performed by the low bidder has been verified to be satisfactory. Staff recommends awarding the construction contract to Bay Cities Paving & Grading, Inc., in the amount of $4,183,298. Consultant Services Construction Management and Inspection Services Swinerton Management and Consulting will provide construction management and inspection services, including the required nighttime oversight. Work within Caltrans’ right-of-way requires a resident engineer and inspector experienced with Caltrans’ standards and procedures. Due to the number of ongoing projects, it is difficult to dedicate one full-time staff member to nighttime inspection and construction management. Staff recommends awarding a professional services agreement to Swinerton Management and Consulting for the not-to- exceed amount of $308,890 for construction management and inspection services. Designer Additional Work and Construction Support Services Consor will provide construction support services to review shop drawings and provide responses to requests for information. Additional design fees are required to cover the cost of the numerous iterations of plan changes and time spent working to meet the varying Caltrans requirements for project DEER approval and securing an encroachment permit.Staff DocuSign Envelope ID: 4F87FD3C-C94B-445D-A7F7-B9041B616CE0
