FULL-PHASE SECURITY FOR EVERY PROJECT
Washington's construction boom means active sites across the Puget Sound are prime targets for theft, trespassing, and vandalism — especially after hours and on weekends. We build security programs that cover every phase of your project from site prep through final inspection.
Mobile Patrol Coverage
Vehicle-based patrol for large sites or multiple project locations — GPS-tracked, documented, and cost-effective alternative or complement to stationary guards.
Site Access Control
Gate management and contractor credentialing to ensure only authorized personnel, subcontractors, and delivery drivers enter your project site.
Fire Watch Services
IFC and NFPA 72-compliant fire watch during and after hot work operations and during fire suppression system impairments — with full documentation for your AHJ.
Equipment & Material Protection
Deterrence and documentation for high-value equipment, copper, lumber, and materials that make construction sites among the most theft-targeted properties in Washington.
Incident & Liability Documentation
Detailed shift logs and incident reports supporting your insurance claims, GC liability protection, and owner documentation requirements.
EQUIPMENT THEFT COSTS WA CONTRACTORS MILLIONS
Construction site theft is one of the most underreported and costliest crime categories in Washington State. Copper wiring, heavy equipment, power tools, and building materials disappear overnight — and the losses compound through project delays, insurance claims, and schedule impacts that affect your bottom line long after the theft.

Construction FAQs
What's the most cost-effective way to secure a construction site overnight?
For most sites, a combination of a stationary guard at the primary access point plus mobile patrol rounds delivers the best coverage-to-cost ratio. The stationary guard controls entry and deters opportunistic intruders, while mobile patrol covers the full site perimeter. For very large sites or multiple project locations, mobile-only patrol can be cost-effective with documented GPS-verified rounds.
Do you provide fire watch for construction sites?
Yes — fire watch is one of our core construction services. We provide IFC Section 901.7 and NFPA 72-compliant fire watch coverage during and after hot work operations and during fire suppression system impairments. Our officers maintain patrol logs that meet your Authority Having Jurisdiction documentation requirements.
