The Need For Building Site Security

The stats concerning construction site theft are frightening.

  • Statistics from insurer Allianz Cornhill show that theft alone costs the construction industry £800M a year
  • A survey conducted by IronmogeryDirect found that more than £100 million of tools have been stolen in the UK since 2020.
  • The Chartered Institute of Building revealed that 92% of respondents to their survey were directly affected by petty crime, with 21% stating that their construction sites were robbed on a weekly basis.
  • According to CESAR (the UK’s Official Construction Equipment Security and Registration Scheme), as little as 5% of unregistered plant is recovered.

FMB CEO, Brian Berry, said: “More than half of builders in the UK have fallen foul of tool theft with concerns growing over a crime wave continuing to wreak havoc across the construction industry. Tools are being stolen from vans and direct from construction sites, with some builders even being assaulted by would-be thieves…”

Tool loss, or the theft of any construction equipment, will incur a significant financial loss, cause disruption and increased downtime which can only extend construction projects and increase costs. This highlights the need for effective construction site security.

Clearway inView solar CCTV Tower

Temporary CCTV Tower (solar or mains)

Our purpose-built CCTV towers can be installed and configured quickly once on-site, providing instant visual security for large open spaces. The CCTV camera is mounted at the top of a 6m telescopic mast, instantly providing near 360-degree coverage, ensuring your site is monitored from all angles.

Our rapid deployment CCTV towers include two large solar panels that recharge a set of high-capacity batteries. Together, they will keep the CCTV tower running 24/7, independently of mains power. Our CCTV towers will also run from 240v mains power should it be available. Requiring very little maintenance, this robust and responsive construction site security solution can be set up within minutes and removed quickly as and when needed.

Clearway ARC

CCTV Monitoring

Our fixed or temporary CCTV systems are set, by default, to record 24/7 and can be viewed via a mobile device or PC from any location.

Multiple passive infrared sensors can be installed to provide trigger points, such as entrances and exits to a site, where a PTZ (Pan, Tilt, Zoom) camera can point and focus on in the event of an activation. These events can be monitored by our NSI Gold Cat ll Alarm Receiving Centre, allowing for round-the-clock surveillance and collection of video footage for evidence, if required.

Additionally, our ARC can monitor intruder and fire alarm activations, video-verified alarm systems and other construction site security systems, to provide a quick reaction and response to breaches in security. You can read more about our remote CCTV monitoring station here.

Clearway inView Detect PIDs on construction site

InView Detect for Building Sites

inview Detect, our innovative wireless intrusion detection system, provides immediate protection for construction sites, where security needs can change swiftly with daily activity shifting the perimeter of the site.

Our autonomous intrusion detection system actively monitors the site, promptly detecting any unauthorised activities or intrusions and triggering real-time alerts. This feature is crucial for preventing theft of construction materials, equipment, and tools, as well as deterring potential trespassers.

The extendable coverage of inview Detect, reaching up to 2000 meters with multiple units, ensures comprehensive surveillance across expansive construction sites. Its adaptability allows for quick repositioning or deployment of additional units, accommodating the evolving layout of construction projects.

The system’s rugged design and tamper-proof features make it resilient to the challenging conditions of construction sites, where robust security measures are essential. inview Detect’s integration capabilities with central monitoring enhance the overall security posture, enabling swift verification of alerts and timely responses to potential security incidents.

Clearway Video verified Alarm System

Video Verified Alarms

Whilst regular alarm systems can monitor movement or changes within a specific area, via a variety of sensor types, there is typically no indication as to what caused an alarm to be triggered, only the activation itself.

Our video verified or visually verified alarm system takes the alarm activation process one step further. As well as sounding a 100db alarm it uses its built-in camera to capture a series of still images, collates them into a ten-second clip of the cause of the activation, and sends it, with a notification, directly to a pre-determined recipient or to our NSI Gold Cat II Alarm Receiving Centre. The appropriate action can then be taken depending on the perceived level of the threat.

Video-verified alarms are a particularly efficient way of monitoring a construction site as both false and genuine alarm activations can be identified immediately, before any response team is deployed, especially for vacant construction sites or areas with low movement expected.

Battery life for all devices, including the control panel, is up to 4 years. A pre-recorded voice challenge can also be added as an option.

Clearway Concrete Barrier Blocks

Concrete Barrier Blocks

Construction sites can typically occupy large, open areas of land with multiple access points, and these can be difficult to protect from unwanted intruders and fly-tippers in particular.

To bolster your construction site security, concrete barrier blocks are an ideal and flexible solution that enable large perimeters to be fully protected with a contiguous, physical barrier, or simply protect a small access point, such as between trees on the edge of roads.

The concrete barriers can be used to restrict vehicle access, preventing thieves who may use vehicles to transport stolen goods.

Fly-tipping is also a major issue on open land or unoccupied land, such when a site is in the early stages of development, should your construction site be left unattended for longer periods of time.

Frequently asked questions

Construction sites are often a target due to:

  • High-value assets, equipment and tools.
  • Open access points and easy vehicular entry.
  • Vacant sites out of hours and during weekends.

Trespassers and intruders can cause costs and damage that have a long-lasting impact.

Many construction businesses have experienced tens of thousands of pounds worth of expenses to replace stolen assets and repair damage, and delays of months while repairs are carried out, due to insufficient security safeguards. Whilst cameras are great for providing evidence after a crime has been committed, by then, the damage is done and the construction project has been delayed until the equipment can be replaced or the damage repaired.

The severe and sometimes business-critical impact of security limitations is far-reaching, and therefore it is crucial to work with an experienced and proficient construction site security partner who can protect your site during every stage of the project.

Construction site security threats are not limited to the theft of tools. In fact, the consequences of a security threat can result in loss of human life so it’s extremely important that all risk are considered to prevent that outcome.  Some of the primary risk factors include:

  • High-value equipment, machine, plant and tools left unguarded overnight.
  • Vehicles left vulnerable to fuel theft when the site is empty.
  • Vandalism and site damage caused by intruders where site access is exposed.
  • Workforce risks where security provisions are not sufficient to provide staff safety.
  • Site risks in controversial areas where protests or demonstrations can disrupt the flow of work, or restrict access to the site.
  • Environmental risks such as fire, flooding and weather damage.

A risk assessment is more than a checklist exercise or an insurance requirement – it is an essential tool to assist construction site managers in clearly identifying key risks, and being able to make informed decisions about the best mitigation strategy.

The risk assessment process typically follows these predefined steps:

  1. Carry out a comprehensive site inspection and identify risks – both primary and secondary.
  2. Record how serious that risk is, and what issues it potentially presents.
  3. Decide which risks are crucial to site operations, to establish a list of priorities.
  4. Work with a security professional to identify the best security safeguards available to eliminate or mitigate that risk and compare alternative options.
  5. Put in place security strategies, and review regularly and whenever site operations change.

One of the most common concerns for construction site managers is in the costs of protecting their premises, and how to balance a tight budget while avoiding critical risks. Therefore, a cost analysis is an integral part of the risk assessment process, where every aspect of the building site security options should be considered:

  • Potential costs of not mitigating the risk factor.
  • Security options and the respective costs of each.
  • Anticipated effectiveness of the security solutions.
  • The element of workforce risk where employee protection is a top priority.

Your risk assessment is also a powerful communication tool, and by sharing these with your workforces, you help all employees remain diligent, understand where risk factors are present, and work with site security to prevent any breaches from occurring.

Your building site security will depend on multiple factors such as hours of work, points of entry, the storage and location of valuable assets, and the flow of traffic around your site.

Generally we advise the following, broken down into three categories: deterrents, detection and response.

Intruder Deterrents:

There should be a number of construction site security measures in place to make opportunistic thieves think twice about attempting a breach. These should include products such as unclimbable perimeter security fencing as well as electronic security features such as CCTV. Consider the following:

  • Visible security presence and signage.
  • Robust perimeter fencing and security access points.
  • CCTV monitoring and maintenance.
  • Manned guarding and construction site access control.
  • Concrete barrier hire to prevent unauthorised vehicular access.
  • Security lighting, alarms and sensors.

You may also want to consider:

  • Restricting the number of vehicles on site and having a sign in / sign out authorisation process in place. This would help to identify non scheduled deliveries or unmarked vehicles with malicious intent.
  • Preventing vehicle access altogether – by implementing turnstiles and restricting access points, you can get a clear picture of who is on the site and when whilst granting access to authorised personnel only.
  • Full and wide reaching lighting – having floodlights or timed lighting not only ensures that staff can work safely, but can prevent vandalism and break ins.

Efficient Detection Systems:

Should your first line of construction site security not deter the offender, there should be a number of detection systems in place to identify a threat as quickly as possible and to provide evidence if needed if a police investigation ensues.

Detection systems are often broken down into operational solutions (those that require human response) and physical detection systems (usually electronic such as CCTV). Whilst operational activities such as manned guarding and patrols increase the level of deterrence, they can be expensive. Physical detection systems such as the solutions outlined below often come at a reduced ongoing cost and prevent any threat to human life. Physical detection systems include:

  • CCTV solutions, infra-red monitoring and wireless sensors to immediately detect activity.
  • Remote monitoring services – this activity is then fed directly to an alarm receiving centre. Those manning the system will immediately review the intrusion and alert those on site (or deploy a rapid response security team to investigate).
  • Construction site access control to vet and approve each visitor.
  • Advanced alarm systems to detect breaches, smoke, or fire.

Response systems

Whilst detecting a threat is the first step in dealing with a security breach on a building site, the response is critical to limiting the amount of damage incurred. By utilising a remote monitoring system, operators can very quickly respond to security breaches, alerting emergency services if needed. Your response solutions should include:

  • Instant intruder alerts with appropriate personnel informed.
  • Intruder detection warning systems.
  • Automatic lock and unlock facilities.
  • Keyholding services to respond to alarm activations and call-outs.
  • Live CCTV imaging, monitoring, and high-quality video retention.
