MEETING DATE: 11/19/2025 AGENDA CATEGORY: Consent – Agreements TO: Honorable Mayor and City Council
FROM: Zachary Meyer, Public Works Director
DATE: 11/3/2025
SUBJECT: Contract Change Order Nos. 10, 22, and 31 to Agreement No. 2024-235 (7th Movement) with Granite Construction Company (increasing compensation by $78,023.58; revised not to exceed $27,710,104.93) for the Centennial Corridor EB58 to NB99 Loop Connector Project. (Wards 1 & 2)
RECOMMENDATION:
Staff recommend approval of the change orders.
BACKGROUND:
The 7th Movement Project proposes to construct a new freeway connector ramp from eastbound State Route (SR) 58 freeway to northbound SR 99. At the SR58/SR99 Interchange, construct a new connector starting west of SR 99, on the south side of 58 with a bridge widening over SR 99, a new bridge spanning over Wible Road, and connecting to northbound SR 99. This project also includes the construction of a bike path from Commerce Drive to California Avenue with a pedestrian bridge over the Carrier Canal, permanent closure of the southbound SR 99 to Stockdale Avenue off -ramp, drainage improvements for the Elcia Drive and Real Road intersection, and installation of permanent barrier at the Ming Avenue to southbound SR 99 on -ramp. This Project was awarded in September of 2024 and has an estimated completion date of August of 2026.
Change Order N o. 10 provides compensation to the contractor for additional removal, disposal, and reconstruction of Separator Bridge Widening approach slab and joint seal. The construction of abutments for the Separator Bridge Widening had a much wider impact on the exi sting approach slab making it necessary to remove more than as shown in the plans. This change order results in an estimated increase of $33,000.00.
Change Order No. 22 provides compensation to the contractor to demolish and reconstruct a portion of Type 60 concrete barrier located at the Ming to northbound SR 99 on -ramp. The concrete barrier was originally part of the Mainline Project, however, it was designed and constructed with a blunt end which was a safety issue for Caltrans and identified as Punch List No. 300 for route adoption. To quickly resolve the safety issue and avoid additional expenses, Granite agreed to perform this work. This change order results in an estimated increase of $17,000.00.
Change Order No. 31 provides compensation to the contractor for the purchase of temporary k -rail and installation within the westbound SR 58 to southbound SR 99 connector, more specifically the outer shoulder of the loop ramp. It was determined that after a couple of incidents of vehicles veering off the roadway and onto private property that a safety issue needed to be resolved. The City agreed to install temporary k-rail at this location near the project as an interim fix prior to the 8 th Movement Project, in which a perman ent barrier would be constructed. This change order results in a net increase of $28,023.58.
FISCAL IMPACT:
The sum of all change orders to date on this project reflects a total cost increase of $ 409,808.13 which results in a 1.50% increase of the original contract amount as illustrated below:
Original Contract Amount = $23,300,296.80
Previous Change Orders = $331,784.55
Current Change Order = $78,023.58
Amended Contract Agreement after CCOs = $27,710,104.93
Net Increase to date = $409,808.13
There is no General Fund impact associated with this change order.
