Score your exposure honestly
Walk the site at the end of a workday — the way a thief would see it — and rate yourself on six factors:
1. What’s staged on site
Copper wire and pipe, lumber, appliances, HVAC units, tools left in gang boxes, fuel — staged materials are the biggest draw. The question isn’t just value; it’s portability and resale. A pallet of copper fittings walks off a site far more easily than structural steel.
2. Equipment left overnight
Skid steers, excavators, generators, compressors, trailers. Equipment theft is a tow-and-go crime, and vandalism — cut hydraulic lines, sugar in tanks, smashed glass — costs schedule even when nothing is stolen.
3. Perimeter quality
Is the fence continuous, tensioned, and gated — or are there gaps behind the spoil pile? Can a pickup back up to the laydown yard? A perimeter that only slows down honest people counts as no perimeter.
4. Lighting and sightlines
Dark sites invite entry; lit sites with clear sightlines from the street get skipped. If your site goes fully dark at night, you’ve raised your score whether you like it or not.
5. Neighborhood incident history
Ask around before you rely on assumptions: what has happened on nearby sites and properties in recent months? Other GCs, your fencing vendor, and neighboring businesses will tell you quickly whether sites in the area have been hit. If yours is the newest site in an area with an active pattern, plan for attention.
6. Project phase
Phase drives what’s stealable. Sitework and foundation phases risk equipment and fuel. Rough-in is the copper phase — wire and pipe in every room, drywall not yet closed. Finish phases stage appliances, fixtures, and cabinets. Exposure isn’t constant across the job; it peaks and moves.
When the risk actually happens
Construction theft is overwhelmingly an after-hours crime, and it clusters:
- Nights — especially the hours after the last trade leaves and before neighbors are awake.
- Weekends — two unobserved days, and a Friday-loaded laydown yard is a standing invitation.
- Holidays and long weekends — three or four quiet days give thieves time to work and a head start before Monday’s discovery.
- Right after big deliveries — material that lands Thursday and installs Tuesday spends the highest-risk window sitting in the open.
This is good news for your budget: you don’t need to buy 168 hours of coverage to cover the windows that matter.
Guard, patrol, or cameras — the decision matrix
| Your situation | Coverage that fits |
|---|---|
| High-value staging, active theft pattern, or an urban site with an open perimeter | Dedicated on-site guard during the risk windows — continuous presence, gate control, live deterrence |
| Moderate exposure, decent fence and lighting, no incidents yet | Mobile patrol — randomized, documented vehicle checks overnight and on weekends |
| Fixed sightlines, power available, budget-sensitive, long project | Monitored cameras with live voice-down — a persistent watch that talks to intruders and dispatches response |
| Peak-value phases (rough-in, appliance delivery) on an otherwise quiet job | Layered: cameras full-time, guard added only for the peak weeks |
| Daytime problems — gate control, deliveries, unauthorized visitors | Day-shift guard on the gate with contractor sign-in and delivery logging |
The models also stack. A common Worcester-area build: cameras across the whole project, patrol on ordinary nights, and a guard for holiday weekends and the copper phase. For the tradeoffs in detail, see guard vs. mobile patrol.
Add and drop coverage as the job moves
Security spend should track the exposure curve, not the calendar:
- Mobilization: establish the perimeter, lighting, and camera positions before the first equipment arrives — retrofitting security after a loss costs more
- Sitework/foundation: patrol-level coverage; equipment and fuel are the targets
- Rough-in: escalate — this is the copper window, and it deserves your strongest coverage
- Finish: keep coverage on delivery-heavy weeks; appliances and fixtures disappear fastest the night they arrive
- Punch list/turnover: step down to patrol or cameras; drop to zero only when the valuables do
A good security vendor will propose this kind of phase-based plan and revisit it at each milestone — if you’re getting a flat quote for the whole job regardless of phase, you’re overpaying somewhere and underprotected somewhere else.
