Most construction sites get a security system after the first significant theft. The sequence is almost always the same: the site gets hit, the general contractor absorbs a bad week, and somebody finally puts a number on what it would have cost to prevent it.

By that point you have already paid the tuition. The tools are gone, the schedule has slipped, and the crew that showed up to work spent the morning taking inventory instead.

The better sequence is to have the conversation at mobilisation, when the site is still a graded lot and nothing has happened yet.

Why construction sites are targeted so consistently

A jobsite is an open-air warehouse with a published schedule.

Anyone driving past can see what stage the build is at, and stage tells you what is on site. Framing means lumber and nail guns. Rough-in means copper and conduit. Mechanical means HVAC units sitting on the ground waiting to be set. Finish means appliances and fixtures in boxes.

Add the conditions: no permanent power, no permanent lighting, a perimeter of temporary fence that changes weekly, multiple subcontractors coming and going so unfamiliar faces are normal, and long stretches — nights, weekends, holidays — with nobody there at all.

And unlike most commercial targets, a construction site has no alarm to trip, because there is nothing to alarm.

The cost is never just the stolen property

Contractors tend to price this by replacement value. That is the smallest part of it.

Schedule. A stolen HVAC unit is not a purchase order, it is a lead time. Every trade behind that item stacks up, and the delay propagates through the remainder of the build.

Labour. A crew that arrives to find their tools gone does not simply switch tasks. They spend the day dealing with it.

Rework and damage. Copper theft means cutting open finished walls. The theft costs a few hundred dollars in scrap; the repair costs thousands.

Liquidated damages. On a project with a hard completion date, delay has a price written into the contract.

Insurance. Builder’s risk claims follow the contractor to the next project and the one after that.

What changes when monitoring goes in at the start

The argument for day-one security is not that the risk is highest at mobilisation. It is that the site develops a reputation from the beginning, before anyone has learned that it is easy.

Sites that get hit once usually get hit again, because the people who took the first load know the layout, the gaps in the fence and the rhythm of the schedule. Preventing the first incident prevents the pattern.

A monitored surveillance unit — towed in, positioned, running on its own power and connectivity — goes up the day the fence does. As the build progresses and the valuable material moves around the site, the unit moves with it.

Live agents, not just a recording

The distinction matters more on a jobsite than almost anywhere else, because police response to a remote or partially built site is rarely fast and the property is rarely recoverable.

With Overwatch, an agent watching the live feed sees someone crossing the site and responds while they are still in the open: a direct voice-down naming what they are wearing and where they are standing, lights, a 110 dB siren, and a call to police with a live description when it is warranted.

Most attempts end at the voice. Somebody who came to load a truck with copper has no interest in being spoken to by name.

Security as a line item, not an emergency

When monitoring is priced at mobilisation it is a predictable cost in the general conditions, with a known start and end date that matches the project. When it is bought after a theft, it is an unplanned expense on top of the loss that triggered it.

Same service. Very different conversation with the owner.
