Construction-site risks MPS mitigates
The six loss events active job sites log most.
California general contractors and developers face a consistent set of loss events on active job sites. These are the six categories our field teams see most frequently — each with a guard-based mitigation that stops the clock before a police report is even filed.
Material & lumber theft
High-value lumber stacks and staging yards are the first target on any job site; an unmanned lot overnight invites flatbed runs that can set a schedule back by weeks.
Copper & tool theft
Pipe, wire spool, and power-tool theft routinely runs $10K–$50K per incident — no police response time beats a guard who is already on-site.
After-hours trespass
Squatters, scrappers, and competing contractors entering the site after lock-up create liability the GC holds and inspection failures the AHJ flags.
Vandalism
Graffiti, equipment sabotage, and site-office break-ins delay the schedule and are rarely covered by standard builder's risk — the GC absorbs the cost.
Hot-work fire risk
Welding, torch-cutting, and brazing on a site with exposed framing and combustible materials require a dedicated fire-watch under Cal/OSHA Title-8 §6078.
Alarm impairment / fire-watch gap
When the sprinkler or fire-alarm system is out of service during rough-in or panel changeout, OSHA Title-8 §3220 and the AHJ require a physical watch on-site until the system is restored.
What we put on-site
Night-watch officers, mobile sweeps, and an OSHA-compliant fire-watch that carries through to the cool-down window.
Every post is GPS-stamped, time-carded, and downloadable from the GC’s dashboard the moment a sweep ends — the same audit trail we bring to every job-site placement.
Night-watch officer
Single licensed guard on-site from lock-up to first call. Perimeter walk of every staging area, equipment yard, and material storage point on the posted cadence. GPS-stamped and time-carded so the GC's site contact can pull the patrol log any time.
Mobile patrol sweeps
Randomized drive-through of the site perimeter at intervals the GC sets. Covers multi-gate footprints and adjacent lots that a posted guard cannot walk alone — every sweep GPS-stamped from the patrol app.
OSHA Title-8 fire-watch
When a hot-work permit is active or the fire-alarm system is impaired, a dedicated licensed guard stays on-site for the duration and the full cool-down window. Permit-ready log book on-site with AHJ signature lines ready.
24-hour dispatch backup
A real human answers the dispatch line at any hour. If a sweep is missed or an incident is observed, the GC's site contact gets a call within minutes — not an end-of-shift email.
California Bureau of Security & Investigative Services Private Patrol Operator. In good standing — BSIS-licensed officers on every post.
Every sweep GPS-stamped from the guard’s patrol app, surfaced in the GC’s dashboard in real time — tightens to meet the AHJ site plan.
Fire-watch log book on-site with AHJ signature lines. Patrol reports, incident logs, and permit documentation exportable on first request.
Typical guard tier pricing
Per-hour guidance so the GC’s project team can quote on the first call.
These are typical California bands — not a published contract. Final quote reflects site geometry, watch duration, footprint size, and whether the scope is a single overnight post or a multi-guard fire-watch rotation.
Unarmed night-watch · single officer
$45–$60 / hr
Standard overnight post, perimeter walk of staging areas, equipment yard, and site office from lock-up to first call.
Mobile patrol · site sweeps
$35–$55 / drive
Randomized vehicle patrol hits every gate and perimeter point on the route sheet; check-in GPS-stamped from the patrol app.
Fire watch · hot-work or impairment
$55–$70 / hr
Dedicated licensed guard for the duration of a hot-work permit or alarm-system impairment. Permit-ready log book on-site.
Fire watch · 24-hour continuous
$90–$120 / hr
Two-guard rotation for multi-floor or large-footprint sites where a single guard cannot cover the cadence across the full watch.
California does not regulate guard pricing. The bands above are a planning estimate from recent construction-site placements in our service area; your brief lands with the fire-watch team lead, who answers within one business day.
