Installation of Physical Deterrent Barriers

Caltrans District 4 in the Bay Area/Oakland is seeking a subcontractor to install non-permanent physical barriers at highway underpasses and roadside areas to deter re-encampments. The work includes the placement of fencing, bollards, planters, and concrete curbing designed to be removable and adaptable without permanent structural changes to public infrastructure. This effort targets high-visibility and high-impact locations where encampments have repeatedly formed, aiming to balance public safety, environmental management, and community needs. The contract falls under NAICS code 238990 for other specialty trade contractors, indicating specialized installation expertise is required. The solicitation was posted in July 2026, with performance expected in locations across Caltrans District 4, though exact sites are not specified. The nature of the work demands careful coordination with local authorities and adherence to transportation regulatory standards, with solutions that are both effective and minimally invasive to surrounding infrastructure and landscapes.
