Fast, Targeted Security Response at the Bristol Railway Arches
In the heart of Bristol’s city centre, a construction project under the railway arches was being held up by more than just the usual logistical challenges. Frequent fly-tipping, trespassing by travellers, and drug use on-site had not only delayed progress but created serious safety concerns for contractors and workers.
Propertysec was called in to turn the situation around fast.
Through the deployment of Sentinel PID MK1 units and a comprehensive monitoring solution, we helped the client regain control of the site, restore safety, and resume construction without further delay.
Project Overview
Client: Commercial construction contractor (confidential)
Location: Bristol city centre – railway arches site
Challenge: Ongoing antisocial behaviour, delays, and site hazards
Solution: 3 Sentinel PID MK1 units with 24/7 remote monitoring
Result: Site secured, intrusions deterred, project resumed on schedule
The Challenge
The client faced growing disruption from antisocial activity, including:
Fly-tipping by travellers
Drug use and littering of syringes
Daily safety risks for workers
Significant project delays and rising costs
The site needed to be secured quickly — without complex infrastructure or lengthy installations.
Our Solution
Faced with persistent antisocial behaviour and urgent client needs, we designed a rapid-response solution built around portable, self-contained units that could be deployed quickly and monitored remotely besides other solutions.
1. Site Clearance
Before any equipment could be installed, the site was cleared of hazardous waste, including syringes and general fly-tipped debris, to make it safe for both workers and security hardware.
2. Deployment of Sentinel PID Units
We deployed three Sentinel PID MK1 units, each strategically placed to provide full site coverage. Each unit included:
4 Reconeyez detectors for wide-area motion and thermal detection
1 integrated siren to produce an immediate, high-decibel alert when triggered
This setup allowed for comprehensive coverage with rapid deterrent response.
3. 24/7 Monitoring
To ensure continuous site protection, all units were connected to our professional monitoring partner. This provided:
Real-time detection and verification
Fast, coordinated response to confirmed intrusions
Full peace of mind for the client, day and night
Results and Impact
Immediate Deterrence
The presence of the PID units, and the loud siren activations discouraged unauthorised access instantly. During post-installation walk tests, the sirens clearly demonstrated their effectiveness as a psychological barrier.
Verified Intrusion Detection
The Reconeyez system detected any movement across the site, and alerts were escalated only when verified — preventing false alarms while ensuring fast intervention.
Construction Resumed
With the security measures in place, the site was declared safe and construction resumed — avoiding further financial losses for the client.
Community Benefit
The improvement in site safety also had a positive knock-on effect in the surrounding area, reducing antisocial activity near the city centre location.
Conclusion
This project demonstrates Propertysec’s ability to respond rapidly to complex urban security challenges. With the right equipment, planning, and monitoring support, we helped restore order and get the project back on track.
Whether you are managing a busy city-centre site or facing persistent trespassing and theft, Sentinel PID units provide fast, flexible protection that works.
