Construction site security
SECURITY SERVICES IN LONDON
Construction sites change as work progresses. Orion provides construction-site security in London, with arrangements planned around the site layout, access points, workforce and the stage of the project.

Security that follows the site’s working arrangements
An assignment can support controlled access, observation of agreed areas and reporting of activity outside normal patterns. We discuss the relationship between the security team, site management, contractors and delivery personnel so that responsibilities are clear.
What the assignment can include
- Managing agreed gatehouse and access procedures
- Checking visitors, contractors and delivery arrivals
- Patrolling designated areas where included
- Observing and reporting damage, suspicious activity or unsecured access
- Keeping site logs and following the agreed escalation process
Plan your service
Provide the location, project phase, operating hours, access layout and areas requiring attention. We discuss site induction, relevant hazards, reporting contacts and changes expected during the assignment. Any static guarding, mobile patrol, lock-up or dog-handling requirement is considered separately and included only where agreed.
Adapt to each project stage
Security arrangements should reflect changes in the project. Temporary entrances, contractor numbers, delivery routes and the location of materials can change over time. Tell us when the site layout or working hours change so the assignment can be reviewed. Unoccupied areas and parts of the site still under construction require particular attention to safe access.
Set practical site boundaries
Discuss inductions, welfare access, protective equipment requirements and any areas the assignment must not enter. The scope should distinguish security duties from site-management decisions, plant operation and specialist safety responsibilities. Agree how observations are reported to the site manager and who can authorise access outside normal working hours.
