Perimeter Bollards and Barriers
Fixed, removable and retractable bollards and anti-climb barriers, designed to deter and control unauthorised vehicle and pedestrian access to vacant and live sites.
Assessed, designed, installed. One team.
Perimeter bollards and barriers, run inside the AOG operating model.
Perimeter bollards and barriers sit inside the same AOG account as void security, cleaning and inspections. One project manager owns the void. One control room holds the keys, monitoring and inspection records. One weekly report covers every visit, incident and finished work order.
You take the service on its own, or alongside the rest of the vacant property division. The covenant, the compliance ledger and the point of contact stay the same either way.
AOG designs and installs bespoke perimeter bollard and barrier systems, designed to deter and control unauthorised access, theft and vehicle movement around vacant properties and live construction sites, with product specification selected to the site risk. Every layout follows an on-site assessment of access routes and weak points, using fixed, removable or retractable bollards depending on how the site needs to be used.

Questions
Frequently asked questions
When should bollards or barriers be used on a vacant site?
Bollards and barriers suit sites where unauthorised vehicle access is a specific risk, such as ram-raid exposure or unwanted vehicle incursion onto a vacant or live construction perimeter. A layout is only proposed after an on-site assessment of access routes and weak points.
What types of vehicle access can be controlled?
Fixed bollards suit permanent control, while removable and retractable options suit sites that need flexible or occasional vehicle access.
Are temporary and removable options available?
Yes. Removable and retractable bollards and collapsible barrier systems are available for sites that need the boundary opened periodically rather than permanently closed.
Can barriers be combined with CCTV and patrols?
Yes. Bollards and barriers are commonly run alongside steel screens, monitoring and mobile patrols as part of one perimeter security record.
How is access maintained for authorised contractors?
The layout is designed around genuine access needs identified in the site assessment, so authorised contractors and vehicles retain access while unauthorised movement is controlled.
