A single construction site theft in BC rarely costs what the stolen items were worth - it costs the items, plus the deductible, plus the schedule slip, plus re-done work, plus the premium increase that follows the claim. When you add those up, a "$15,000 equipment theft" routinely becomes a $40,000-$60,000 project problem. That math is why site security is not an expense line - it is delay insurance. Here is the full cost picture, and what actually prevents it.
The theft targets on every BC site
- Copper and wire - stripped from rough-in within hours; the single most damaging theft type because it destroys completed work
- Power tools and small equipment - easiest to fence, first to vanish from unlocked containers
- Fuel - siphoned from machinery on unfenced sites
- Heavy equipment and attachments - skid steers and mini-excavators stolen to order
- Building materials - lumber packages, appliances, and fixtures near project end
The real cost stack (worked example)
Take a mid-size Okanagan or Lower Mainland project hit by a copper strip during electrical rough-in:
- Stolen material (copper, wire spools): $8,000 - $20,000
- Re-doing completed rough-in labour: $10,000 - $30,000
- Insurance deductible: $2,500 - $10,000
- Schedule slip (trades resequencing, penalties): 1 - 4 weeks of overhead
- Premium increase at renewal: Years of higher cost
- Second-hit risk: Thieves return to soft targets
That last row matters most: sites that get hit once get hit again unless something visibly changes. Word travels.
Why construction is targeted (and when)
Vacant hours are the whole story - most sites sit empty 12+ hours on weekdays and 60+ hours across a weekend, with valuable, portable, fenceable goods inside a perimeter that says nobody is watching. Risk peaks:
- Phase peaks: electrical/mechanical rough-in (copper) and finishing (appliances/fixtures)
- Time peaks: weekends, long weekends, and the dark months
- Situational peaks: after deliveries, and after any prior incident
We map coverage to these phases in When Does a Construction Site Need Security in BC?
What actually prevents it
In effectiveness order for typical BC sites:
- Visible, unpredictable presence. Random-timed mobile patrols with GPS-verified visits remove the "nobody's watching" signal at a fraction of static cost - and a dedicated night guard during copper and finishing phases is the strongest deterrent available.
- Hard targets: locked containers bolted down, machinery immobilized and keyed out, fuel tanks locked, delivery timing that avoids weekend dwell.
- Lighting and sightlines: dark corners are staging areas.
- Documented access control: who is on site, when, verified at the gate during work hours.
- Reporting discipline: photographed, time-stamped logs mean fast police reports and clean insurance claims when something does happen.
Fireball adds drone-assisted night sweeps for large sites - aerial night-vision passes that cover ground patrols cannot see quickly.
The break-even calculation for your project
Overnight patrol coverage for a site might run a few hundred dollars a week; a night guard during a six-week rough-in phase costs a few thousand. Compare either number against the cost stack above from one incident - plus your deductible alone. For most projects past the framing stage, security pays for itself by preventing a single event.

Frequently asked questions
What is stolen most from construction sites in BC? Copper/wire, power tools, and fuel - with copper theft the most damaging because it destroys completed work and forces re-dos.
When is theft risk highest? Weekends and overnight during electrical rough-in and finishing phases - vacant hours plus high-value, portable goods.
Is site security worth it for small projects? Usually yes once rough-in begins: a few patrol visits nightly costs far less than one deductible plus schedule slip.
Does security help with the insurance claim if theft still happens? Yes - GPS-verified logs, photos, and incident reports give adjusters documented diligence and a clean timeline, which speeds claims and defends against denial.
