ADMINISTRATIVE REPORT
MEETING DATE: 1/22/2025 AGENDA CATEGORY: Consent Calendar – Agreements TO: Honorable Mayor and City Council
FROM: Zachary Meyer, Public Works Director
DATE: 1/8/2025
SUBJECT: Contract Change Order Nos. 51 and 73 to Agreement No. 19-069 Contract Change Orders with Security Paving Company (increasing compensation by $51,037.71; revised not to exceed $151,903,697.00) for the Centennial Corridor Mainline Project. (Wards 1, 2, & 3).
RECOMMENDATION:
Staff recommends approval of the change orders.
BACKGROUND:
The Centennial Corridor Mainline Project (Project) proposes to extend State Route 58 (SR-58) from the current terminus as a freeway at State Route 99 (SR-99) to the Westside Parkway. At the SR-58/SR-99 interchange, the Project adds a collector-distributor on the northbound SR-99 and constructs a new northbound to westbound connector. The Project also includes various local road improvements including; realignment and introducing cul-de-sacs at the end of local roads along the corridor, widening and realignment of Chester Avenue at SR-58, and construction of a traffic signal at the eastbound SR-58 ramps/Brundage Lane intersection (which is part of the SR-58/Cottonwood Road interchange). This Project was awarded in July of 2019.
Change Order No. 51 decreases compensation to the contractor as a result of eliminating the installation of a signal pole and items related to this elimination at the north side of the Brundage Lane and westbound 58 ramp. This change was due to a conflict between the new signal pole and an overhead high voltage power line at the same location. This change order results in a net decrease of $11,262.29.
Change Order No. 73 provides compensation to the contractor to keep falsework material in place at Marella Way Overcrossing beyond the planned release date to accommodate Calwater’s installation of water line in the bridge. The plans had to be revised to include a water line in the bridge and a request was made for additional time for Calwater to install the casing prior to the concrete deck pour. Calwater agreed to compensate the City for the cost to keep the falsework material in place during the extended period. This change order results in an estimated increase of $62,300.00.
The Contractor has refused to sign these change orders alleging additional time and money. However, the Contractor needs to substantiate the request for time and money. In a good faith effort to make payments to the Contractor, staff recommends unilateral approval of these change orders using the engineer's calculated quantities and without the Contractor's signature. If the Contractor later submits acceptable justification for revisions to this change order, staff will review the additional information and, if changes are warranted, a supplemental change order may be in place on a future City Council Agenda.
FISCAL IMPACT:
The sum of all change orders to date on this project reflects a total cost increase of $4,890,040.75 which results in a 3.33% increase of the original contract amount as illustrated below:
Original Contract Amount = $147,013,656.25
Previous Change Orders = $4,839,003.04
Current Change Orders = $51,037.71
Amended Contract Agreement after CCOs = $151,903,697.00 Net Increase to date = $4,890,040.75
There is no General Fund impact associated with this change order.
Funding for these change orders is available in project TRCC21 Centennial Corridor Phase 4 Mainline.
COUNCIL GOAL:
