MEETING DATE: 4/9/2025 AGENDA CATEGORY: Consent – Agreements TO: Honorable Mayor and City Council
FROM: Zachary Meyer, Public Works Director
DATE: 3/26/2025
SUBJECT: Contract Change Order Nos. 4 and 11 to Agreement No. 2024-235 Contract Change Orders with Granite Construction Company (increasing compensation by $67,000.00; revised not to exceed $27,388,837.80) for the Centennial Corridor EB58 to NB99 Loop Connector Project (7th Movement). (Wards 1 & 2)
RECOMMENDATION:
Staff recommends 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 conne cting 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. 4 provides compensation to the contractor for additional costs related to resequencing the permanent closure of the southbound SR 99 to Stockdale off-ramp. The closure has changed from the first order of work to the last order of work. Costs for this change include import borrow needed because the intended excavation material at the off-ramp would no longer be available as fill material. This change order results in an estimated increase of $56,000.00.
Change Order No. 11 provides compensation to the contractor for the removal and disposal of previously unidentified asbestos containing materials near Bent 2 of the bridge widening and at an electrical box on eastbound SR 58 over SR 99. This change order results in an estimated increase of $11,000.00.
FISCAL IMPACT:
The sum of all change orders to date on this project reflects a total cost increase of $ 88,541.00 which results in a 0.32% increase of the original contract amount as illustrated below:
Original Contract Amount = $23,300,296.80
Previous Change Orders = $21,541.00
Current Change Orders = $67,000.00
Amended Contract Agreement after CCOs = $27,388,837.80
Net Increase to date = $88,541.00
There is no General Fund impact associated with this change order.
