ADMINISTRATIVE REPORT
MEETING DATE: 2/12/2025 AGENDA CATEGORY: Consent – Agreements TO: Honorable Mayor and City Council
FROM: Zachary Meyer, Public Works Director
DATE: 1/29/2025
SUBJECT: Contract Change Order Nos. 22 and 158 to Agreement No. 19-069 with Security Paving Company (decreasing compensation by $60,508.22; revised not to exceed $151,908,188.78) 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. 22 decreases compensation to the contractor due to modifications to the length, height, and joint spacing of the screen walls. The layout of some walls also had to be revised due to conflicts with utilities . In general, the length of walls w as reduced. This change order results in an estimated decrease of $80,508.22.
Change Order No. 158 provides compensation to the contractor for performing additional traffic control and flagging. Per standard specifications, City and Contractor share the cost for flagging. Traffic control work includes moving barricades, moving and repainting Type K b arrier, and repositioning and repairing temporary crash cushion modules. This change order provides additional funds for Change Order Nos. 41 and 82 which have been depleted. This change order results in a net increase of $20,000.00.
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 cha nge 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 $4,894,532.53 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 = $4,955,040.75
Current Change Orders = -$60,508.22
Amended Contract Agreement after CCOs = $151,908,188.78 Net Increase to date = $4,894,532.53
There is no General Fund impact associated with this change order.
Federal, State, and Local f unding for these change orders is available in project TRCC21 Centennial Corridor Phase 4 Mainline.
