Home My WebLink About5.3 Iron Horse Nature Park and Open Space Phase 1 Project, CIP No. PK0422 – Contract Change Order Authorization STAFF REPORT CITY COUNCIL Page 1 of 3 Agenda Item 5.3 DATE: November 4, 2025 TO: Honorable Mayor and City Councilmembers FROM: Colleen Tribby, City Manager SUBJECT: Iron Horse Nature Park and Open Space Phase 1 Project, CIP No. PK0422 – Contract Change Order Authorization Prepared by: Andrew Russell, Public Works Director EXECUTIVE SUMMARY: The City Council will consider increasing the contract change order authority of the City Manager by $240,000 for the Iron Horse Nature Park and Open Space Phase 1 Project, CIP No. PK0422. This will enable a change to the contract with Goodfellow Bros. California, LLC to compensate the contractor for costs due schedule delays associated with environmental resource agency restrictions and permitting, as well as for additional work requested by the City. STAFF RECOMMENDATION: Adopt the Resolution Authorizing the City Manager to Approve Contract Change Orders with Goodfellow Bros. California, LLC for the Iron Horse Nature Park and Open Space Phase 1 Project, CIP No. PK0422. FINANCIAL IMPACT: The total additional cost associated with schedule delays and additional work is estimated at $240,000. Sufficient funds are available within the Iron Horse Nature Park and Open Space Project (CIP No. PK0422) to cover these expenses. DESCRIPTION: On October 17, 2023, the City Council awarded a construction contract of $3,324,491 to Goodfellow Bros. California, LLC for the Iron Horse Nature Park and Open Space Phase 1 Project, CIP No. PK0422, and authorized the City Manager to approve change orders up to a contingency amount of $335,000 (Resolution No. 108-23). On November 19, 2024, the City Council authorized the City Manager to approve change orders up to an additional contingency amount of $400,000, which brought the total change order authorization to $735,000 and a total potential construction contract amount to $4,059,491 (Resolution 133-24). 25 Page 2 of 3 The Iron Horse Nature Park and Open Space Phase 1 Project is under construction and approximately 90% complete. The contractor has completed grading activities and contaminated soil removal, bridge and culvert construction, pathway paving, and enhancements to Stagecoach Park. Remaining activities include wetland restoration, final planting and landscaping, installation of remaining park furniture, fencing at Amador Valley Boulevard, and punch list corrections and final project closeout. Work in and around the regulated streams and wetlands is restricted by the permits from three resource agencies: the Regional Water Quality Control Board, the U.S. Army Corps of Engineers, and the California Department of Fish and Wildlife. Although pre-application engagement was conducted and permit applications were submitted to the agencies in April 2023, the final permit to construct was not issued to the City until September 2024. Because activities within the regulated areas are limited to the dry season, the project schedule was updated and work within the jurisdictional areas was delayed until mid-April 2025. In November 2024, the City Council approved a $400,000 increase in contract change order authority, which addressed additional contractor overhead cost associated with the construction delay and increased project costs due to increased material costs, storage costs, and construction of a new haul road necessary to avoid the streams and wetlands. To date, three project change orders totaling $703,312 have been approved, as follows:  Change Order 1 - $136,057 for additional costs for deleterious soil testing protocols, asbestos mitigation during railroad trestle bridge removal, and initial time-related overhead due to regulatory agency delay of work from April 29, 2024, to May 31, 2024.  Change Order 2 - $373,719 for additional costs related to working beyond 2024 due to unanticipated resource agency permit restrictions and material storage costs; increased costs for the arch bridge culvert due to decreased soil bearing pressure ; and Stagecoach Park improvements (privacy fence, irrigation, grading, air relief valve , and drainage at trees).  Change Order 3 - $193,536 for additional negotiated costs for time-related overhead due to regulatory agency delay of work from June 1, 2024, to August 16, 2024. The impact of the regulatory agency permit delay is greater than initially anticipated. In addition to delayed schedule, the means and methods required of the contractor created inefficiencies that resulted in extra work and increased costs, as follows:  A single haul route in and out of the project work area to avoid the streams and wetlands, instead of circular access as was originally planned, resulted in increased contractor time and costs.  The inability to excavate spoils and immediately place them into the path prism (former railroad areas) and inability to store spoils onsite for future work created costs associated with additional off-haul of materials approximately six months later.  Additional hydroseed application was required in and around the wetland areas. 26 Page 3 of 3  The pushing of the project schedule moved contractor wages from 2024 to 2025 rates and extended the contractor’s overhead costs. Additionally, project costs also increased due to the following Staff-requested additional work items:  Installation of additional two-rail wooden fences along Amador Valley Boulevard and a pathway entrance to Stagecoach Park.  Installation of traffic detector loops at Amador Valley Boulevard.  Painting of the exposed timber elements at railroad amenity shade structure. To compensate the contractor for work described above, Staff requests that the City Council authorize an additional $240,000 of change order authority to the City Manager. This will bring the total authorized change order authority to $9 75,000 and will increase the total potential construction cost to $4,299,491. There are sufficient funds available in the project budget to accommodate the increased change order authorization. STRATEGIC PLAN INITIATIVE: None.
