Highlighted Project

Rialto Rails-to-Trails

City of Rialto, CA

Construction Management for Rails-to-Trails Project

Willdan provided construction management services for the award-winning Rails-to-Trails project, which linked transportation networks and established a 21-mile route between Rialto and Claremont for walkers, runners, and bicyclists. Willdan managed all phases of construction – including constructability review, bid selection, coordination with the utility and general contractor, construction oversight, and monitoring federal labor compliance and project schedule and costs.

Willdan successfully handled requests for information, submittals, change orders, and project closeout, delivering this $4 million project on-time and within budget. The City of Rialto won an Achievement Award for Sustainability from the Southern California Association of Governments for this project.

Bolivar Runoff Capture simulation

City of Lakewood, CA

Bolivar Park Stormwater and Runoff Capture Project

Willdan provides construction management and public works observation services for an innovative, $9 million stormwater capture project in Bolivar Park. Lakewood is the first city in California to repurpose their stormwater in this way, transitioning almost entirely away from the use of drinking water for park irrigation.

The City will capture water during light to moderate rainfall in the Los Cerritos Channel using an inflatable dam, then pump the water to a reservoir beneath Bolivar Park, where it will be cleaned and used to irrigate the park. Some of the water from the reservoir will seep into the ground beneath it, replenishing groundwater aquifers. As part of this project, Willdan oversees the construction of a 2.9 million-gallon underground storage reservoir, a 20 cubic-foot-per-second pump station, and a rubber dam that will act as a channel diversion.

Harvey County Courthouse Energy Upgrades

Harvey County Courthouse - Newton, KS

Construction Management for System Upgrades

Our team worked closely with Harvey County administrators to develop a comprehensive solution to address the maintenance, comfort, and energy savings needs of their facilities. Willdan managed the successful delivery of the resulting construction project, including window replacements, the installation of a new high-efficiency geothermal heat pump and HVAC controls, plumbing fixture replacements, and LED upgrades. We prioritized facility improvements that provided more immediate paybacks through energy savings to help Harvey County offset the costs of more capital-intensive system upgrades.
