Thames Tideway Tunnel
09.2017 - 01.2026
- Ensured secure access by verifying credentials of personnel entering specific zones based on risk assessments.
- 24/7 Manned Entry: Personnel provided round-the-clock entry management, cross-referencing worker credentials to maintain a strict, real-time log of exactly who was on-site at any given time for safety accountability.
- Managed gatehouse functions to control access for all arriving vehicles, acting as traffic marshals to ensure safe flow of heavy goods vehicles (HGVs) and specialised machinery at tightly confined urban sites across London.
- Delivery Verification: They logged delivery manifests, checked driver site safety compliance (such as verifying mandatory FORS accreditation requirements), and safely directed vehicles through crowded site gates.
- First Responder Duties: Because workers operated up to 60 metres below ground under high hydrostatic pressures, the security team was trained to act as immediate first responders.
- Hazard Reporting: Officers monitored sites for immediate health and safety hazards (e.g., perimeter breaches, fire risks, equipment failures) and maintained strict compliance logs to support Tideway's overarching zero-harm safety culture.
- Barge and Waste Security: Unlike standard land-based construction, the Tideway project relied heavily on the River Thames to transport excavated materials and tunnel segments via barge. Security officers adapted their duties to monitor a high volume of waterside activity and marine logistics, preventing unauthorised river-based access to cofferdams and reclaimed tidal land.
- Managed waterside activities to prevent unauthorised access to construction areas along the Thames..
- Managed logistics and traffic flow to ensure efficient movement of vehicles and materials.
- Perimeter Integrity Patrols: conducted continuous physical sweeps of complex boundaries, particularly where construction met public spaces or the London foreshore, to deter urban explorers, protesters, and trespassers from entering high-risk environments.
- Monitored surveillance systems for perimeter protection, ensuring comprehensive site security.
- Monitored advanced Avigilon intelligent camera networks, automated number plate recognition (ANPR), and infrared/motion sensors from localised and central command hubs to enhance security oversight.
- Tunnel Zone Restrictions: to secure checkpoints on zones closest to the deep tunnel shafts.
- Officers ensured that only workers with specialized deep-tunnel credentials, specific safety training, and valid CSCS (Construction Skills Certification Scheme) qualifications could enter these hazardous areas.
- Security officers on the Tideway project operated under Effects-Based Security Design principles—similar to protocols used at critical national infrastructure like nuclear power plants. Their specific on-site duties included:
- During the construction of the Thames Tideway to manage and protect over 20 highly complex, high-risk riverfront sites.
- Health, Safety & Incident Response.
- A mobile driver security officer key holder: night shift mobile driving and visiting central zone responsible for safekeeping property access credentials and providing rapid, on-site response to alarms and to secure incidents
