Construction Site Security Guards in Southern California

Construction site security guards from CAL Security Group hold the gate while crews work and walk the fence line after they leave, logging deliveries and subcontractors and writing up each round for the superintendent.

Overview

What a Construction Site Guard Protects

A construction site security guard controls who comes through the gate and checks the site after the crew leaves, so the tools, wire and equipment are still there in the morning.

Job sites lose the most at night and over weekends, when a chain-link fence is all that stands between the street and a spool of copper wire. A break-in can also mean a cut fence the inspector notices, a fire in a trash bin, or a trespasser hurt in an open trench.

What needs guarding changes as the build moves: equipment and fuel on an open lot, then lumber and wire once framing is up, then ranges, water heaters and fixtures in rooms that do not lock yet. Our officers hold guard cards from the Bureau of Security and Investigative Services (BSIS). More on how sites lose material: construction site theft prevention.

On the Post

What the Officer Does on Each Shift

Day and night shifts are different jobs; the post orders spell out both.

  • Log every truck at the gate: company, driver, plate and time
  • Sign in subcontractors against the superintendent's list
  • Check fence panels, gates, containers and locks on every round
  • Walk the building shell for trespassers, running water and lights left on
  • Note equipment hour meters and fuel levels at lock-up, if the post orders ask
  • Photograph cut locks, damage and missing material for the report

Standing Guard or Patrol Visits: Which Fits Your Site

A standing guard fits a site with valuable material on the ground overnight; patrol visits fit a small, fenced site where little is left out.

For example, a tract of homes at finish stage in the Inland Empire, with appliances in every garage, needs a person on site all night. A podium building in Koreatown with a locked materials cage and one gate may only need a lock-up and patrol visits between midnight and 5 a.m.

We tell you which fits after the site walk. Check your builder's risk policy too; some carriers set conditions on fencing, lighting or security.

Post Orders

What the Post Orders Cover on a Job Site

Every CAL post runs on written, site-specific post orders. On a construction site we build them from a walk with your superintendent.

1

Site walk

The fence line, gates, lay-down yard, job trailer and the building itself, noting where lighting is poor or a fence panel can be lifted.

2

Access rules

Who may enter after hours, which subcontractors hold keys, where deliveries park and who signs for them.

3

Round checklist

Gates, fence panels, containers, equipment, fuel tanks and each floor of the building.

4

Call list

Who the officer calls, and in what order, for a break-in, a fire, a water leak or an injured trespasser. Police and fire come first.

FAQ

Construction Site Security Questions

Do I need a guard if the site already has cameras?
Yes, if valuable material sits on site overnight. Cameras record a theft; a guard is there to interrupt it. Many sites use both: cameras on the yard and an officer who checks camera alerts in person.
What does the officer do if someone is on site at night?
The officer keeps a safe distance, calls police, and watches and records until they arrive. On a dark site with trenches and rebar, calling and observing is the safe move, not a chase. Everything goes in the shift report with times.
How many guards does a construction site need?
The length of the fence line and what sits inside it set the number. One officer can hold the gate and walk a compact site. A spread-out tract with several entrances may need a gate officer plus a rover.
Can you cover only nights, weekends and holiday shutdowns?
Yes. Those are the longest stretches without a crew on site. The post orders stay the same; only the schedule changes.
Will you name our company on your insurance certificate?
Yes. CAL carries at least $1,000,000 in general liability coverage per occurrence, the minimum California sets for a Private Patrol Operator, and sends a certificate naming your company before the first shift.
