body
Background:
On December 17, 2024, City awarded the construction contract C2025-05 to United Pavement Maintenance, Inc. (“UPM”) for $2,995,249.25 and approved a project contingency of $300,000.
As of September 2025, the following contingencies totaling $246,910.12 have been approved:
• $206,910.12 in Field Directives for
o Americans with Disabilities Act compliant curb ramps at the Main Street intersections with Alameda Street, Northgate Drive, and Jason Street
o Tree removal and concrete curb, gutter, and sidewalk repair near Edison Street & Main Street intersection
o Concrete median modification at the northbound Main Street left turn lane into Parkwest Casino driveway and at the southbound Main Street left turn lane into Cardoza Center driveway
o Pedestrian fence footing connection change to base plate
o Replacement of faulty electrical conductors and cables at Alameda Street & Main Street intersection
o Additional Iteris traffic signal video detection extension modules
o Additional pavement rehabilitation at the Alameda Street & Main Street intersection
• $40,000 for TRC Engineers, Inc. for additional Construction Management and Inspection Services
During the installation of the new concrete median, a layer of concrete was discovered below the existing asphalt pavement. This information was not known during design and was not discovered as part of the project site investigations. The design consultant, Mark Thomas, recommended the addition of geosynthetic fabric to mitigate against future reflective cracking.
UPM provided City staff with a cost estimate of approximately $340,428.00 for the placement of the geosynthetic fabric across the full road width. City worked with Mark Thomas and UPM to secure pricing from multiple geosynthetic fabric manufacturers and was able to arrive at a negotiated installation cost of $127,660.50.
Staff is requesting City Council to approve an additional $96,125.51 in project contingency to maximize the Project improvements.
