RECOMMENDATION
title
Approve Amendment No. 2 to Agreement No. 250223B with Bureau Veritas for a contract maximum of $1,265,795 for construction management services to support the construction of the Dry Creek Road Bridge. (Fiscal Impact $1,265,795; Capital Improvement Fund; Budgeted; Discretionary)
body
BACKGROUND
The Dry Creek Road Bridge over Dry Creek is 0.8 miles west of Mt. Veeder Road, over 100 years old, and in need of replacement. Caltrans identified the bridge as structurally deficient, functionally obsolete, and unstable due to scour under the north abutment. The width is only 18 feet between the bridge barriers, which does not meet the Association of State Highway and Transportation Officials (AASHTO) standard of 11-foot minimum lanes.
The proposed bridge structure would consist of an approximately 80-foot-long by 32-foot-wide single-span concrete slab bridge that is constructed on pre-cast and pre-stressed concrete girders. The project also includes 900 feet of new roadway to remove two curves in Dry Creek Road. County staff anticipates that the contractor will build the project in four stages to minimize the disruption to traffic and this would require work in Dry Creek over two summers.
After County staff conducted a competitive solicitation for construction management services, the Board awarded Agreement No. 250223B to Bureau Veritas on November 12, 2024. The original Agreement’s scope was limited to constructability review to address potential issues and conflicts before the construction work was put out to bid.
On May 6, 2025, the Board awarded the competitively bid construction contract to Gordon N. Ball, Inc., approved Amendment No. 1 to Agreement No. 250223B with Bureau Veritas for additional pre-construction services, and approved a budget amendment for the construction phase.
County staff negotiated Amendment No. 2 to Agreement No. 250223B, County Counsel approved it as to form, and staff recommends approval of Amendment No. 2 for the introduction Task 2 - Construction Services and Task 3 - Post-construction Services. There is an adequate budget for this expense.
Requested Actions:
1. Approve Amendment 2 to Agreement No. 250223B to Bureau Veritas of Sacramento, California for construction and post-construction services.

Additional Information |
Dry Creek Road is designated as a “minor collector”, the existing bridge is an “Off-System" bridge and thus the project is eligible for 88.53% Highway Bridge Program (HBP) funding and 11.47% Toll Credits funding as the match for local funds; however, there are some expenses that are ineligible for federal funding. In Fiscal Year 2016-17, the Board budgeted $958,420 from the Roads Fund to cash flow the consultant and County staff expenses during design/engineering. On July 13, 2021, the Board approved Amendment 1 with BCA and a $321,054 budget transfer from the Measure T fund.
