MEETING DATE: 1/7/2026 AGENDA CATEGORY: Consent – Agreements TO: Honorable Mayor and City Council
FROM: Zachary Meyer, Public Works Director
DATE: 12/16/2025
SUBJECT: Contract Change Order Nos. 16 and 17 to Agreement No. 2024-235 (7th Movement) with Granite Construction Company (increasing compensation by $158,885.36; revised not to exceed $27,926,329.43) 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 S R 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 No. 16 provides compensation to the contractor to construct an additional 219 cubic yards (CY) of Jointed Plain Concrete Pavement (JPCP). The footprint of JPCP located within the 99 median and beneath the separator bridge equates to a much larger quantity than the 14 CY st ated in the plans. The error was confirmed by the designer of record and corrected to be 233 CY. This change order results in a net increase of $130,000.00.
Change Order No. 17 provides compensation to the contractor for revisions to Drainage System 24. This includes a change in pipe size from 36” RCP to 30” RCP due to a conflict with the new column footing located within SR 99 median. The 36” RCP had already been procured by the contractor and the City elected to keep the pipe for future use. The contractor was directed to deliver the 65 linear feet of 36” RCP to the Union Avenue/Truxtun Avenue storage. Cost includes inefficiencies, delivery of the unused pipes, and removal of the existing drainage system. This change orde r results in a net increase of $28,885.36.
FISCAL IMPACT:
The sum of all change orders to date on this project reflects a total cost increase of $ 626,032.63 which results in a 2.29% increase of the original contract amount as illustrated below:
Original Contract Amount = $23,300,296.80
Previous Change Orders = $467,147.27
Current Change Order = $158,885.36
Amended Contract Agreement after CCOs = $23,926,329.43
Net Increase to date = $626,032.63
