AGENDA MATTER:
CONTRACT AMENDMENT FOR MAIN STREET REHABILITATION - 1 ST AVE. TO BARSTOW ROAD PROJECT (CITY OF BARSTOW PROJECT # ENCD-26-0042)
EXECUTIVE SUMMARY:
On August 18, 2026, the City Council awarded the Main Street Rehabilitation Project - First Avenue to Barstow Road, to Sully-Miller Contracting in accordance with the California Public Contract Code and the City of Barstow Purchasing and Contract Policy. Construction began on September 8, 2026.
During construction, staff identified additional areas of deteriorated sidewalk and asphalt pavement within the project limits that required rehabilitation to provide a complete and satisfactory finished project. Staff directed Sully-Miller Contracting to perform this additional work on a time-and-materials (T&M) basis to address the unforeseen conditions efficiently and minimize impacts to the construction schedule.
Additionally, during asphalt milling operations, existing Petromat pavement reinforcement fabric was encountered within portions of the roadway. The material required additional removal and remediation before placement and compaction of the new asphalt wearing course. This unforeseen work was also performed on a T&M basis to prevent delays and allow construction to continue.
As a result of the additional sidewalk and pavement rehabilitation, Petromat removal, and associated unforeseen construction activities, an additional $75,000 is required to fully fund the project. Staff is requesting that the City Council authorize the appropriation of $75,000 to the Main Street Rehabilitation Project budget to fund these additional project costs and provide sufficient funding for completion of the remaining work.
DISCUSSION:
During construction of the Main Street Rehabilitation Project - First Avenue to Barstow Road, staff identified unforeseen field conditions and additional areas requiring rehabilitation that were not included in the original scope of work. These conditions included deteriorated non-compliant sidewalk and asphalt pavement within the project limits that required repair to provide a complete and acceptable finished project.
To address these conditions efficiently and avoid delays to the construction schedule, staff directed SullyMiller Contracting to perform the additional sidewalk and asphalt rehabilitation on a time-and-materials (T&M) basis. Utilizing T&M allowed the contractor to proceed with the necessary work as the conditions were identified rather than suspending construction while quantities and costs were separately negotiated.
During asphalt milling operations, the contractor also encountered existing Petromat pavement reinforcement fabric beneath portions of the roadway. The Petromat interfered with the milling operation and required additional removal and remediation before the roadway surface could be properly prepared for placement and compaction of the new asphalt wearing course. This work was also performed on a T&M basis in order to maintain the project schedule and minimize construction delays.
