5 Construction Site Security Risks You Haven’t Considered
Beyond the obvious plant theft: the construction security risks that quietly cost projects time and money — and how to close them.
Most construction security conversations start and end with plant theft. It's a real and expensive problem — but it's also the risk everyone already plans for. The losses that hurt most are the ones nobody costed in. Here are five.
1. Delivery-window vulnerabilities
Deliveries create predictable gaps in your perimeter. Gates open, attention is on the logistics, and an opportunist walks in behind the lorry. A guard who knows your delivery schedule — because they've been on your site for months — spots the vehicle that doesn't belong.
2. Fuel and consumables
Red diesel, copper and cabling rarely make the incident report until the totals add up across a quarter. Active CCTV monitoring during patrols turns these slow bleeds into flagged events.
3. Trespasser liability
An injured trespasser is still a liability exposure. First/last patrols document the secured state of your site, which matters enormously if a claim is ever made.
4. Subcontractor access creep
As phases change, so do the people with legitimate access. Without documented assignment instructions under BS 10800, "who should be here" becomes a guess. With them, it's a checklist.
5. The handover gap
Shift changes are the classic weak point. Rotating, unfamiliar guards lose context at exactly the wrong moment. Continuity — the same guards for years — closes that gap.
The common thread: every one of these is a prevention problem, not a reaction problem. That's the whole point of a free risk assessment — to find them before they cost you.
