Overview

Why Job Sites Are a Target, and How We Stop It

Construction site security is guards, patrols, and access control that protect equipment, materials, and entry points on active and idle job sites, cutting theft, vandalism, and liability. Learn more about security guards on Wikipedia.

Tools, copper, and heavy equipment make job sites a frequent target after hours. Officers control who enters, log deliveries and contractors, and patrol the perimeter so the project stays on schedule and on budget. Our officers are state-licensed through the California Bureau of Security and Investigative Services (BSIS).
