A Guide To Different Types Of Construction Security

Difficult to secure and full of high-value materials, equipment and machinery, construction sites can often be seen as an easy target for criminals. So it’s important that you take security on your construction site seriously. In this guide we walk you through why security is important and the different ways in which you can reduce the risk of theft and vandalism at your construction site.

Why is construction security essential?

There are many reasons why you may want to ensure the security of your construction, with the obvious being the potential loss of expensive materials and equipment, there are also further reasons which can often be overlooked but could have a massive effect on your business.

One of the main effects is delays to your work. Not only does losing materials and equipment have a direct financial impact, but it will also affect your ability to work at the site. This can lead to delays in completion which can lead to delays in payments for work being completed and therefore lead to cash flow issues.

There is also potential for threats to human wellbeing in some instances of theft or vandalism, with potential harm coming to your employees or members of the public due to the construction site being tampered with.

How do you ensure security on a construction site?

Construction site security begins with understanding the risks that a particular site faces, its weak security spots, and how these may be addressed.

Risk assessment

A detailed risk assessment will identify and list the range of security risks that the construction site needs to address. It will determine how severe the risk is and the kind of security measure required to reduce the risk.

The risks should be prioritised in terms of the threat they pose, and an audit taken of what existing security measures are already in place. The risk assessment process should be regularly reviewed, considering any changes that have taken place on-site and what security measures have been implemented and how they are performing.

Not every member of the on-site workforce needs to be involved in the risk assessment process. However, they should be aware of the risks, the security measures in place and their role in ensuring the site is secure.

A fourfold approach to construction site security

Construction site security is best understood as a range of measures and approaches that, taken together, help to create a coherent defence against theft and vandalism:


Most thieves are opportunistic, and that applies to construction sites as much as it does to domestic property. Opportunists can be deterred with visible security measures that change their risk/reward calculation in favour of risk. This is likely to include a difficult to scale or breach perimeter fence or security hoardings, securely locked access gates that can’t be climbed or lifted and visible CCTV.

In some instances, it may include on-site security dogs or guards. The more these you have in place, the more difficult your site will look to breach and profit from.


The second aspect of any construction site security system is detection. This serves two purposes: first, to detect an active threat early on and provide some tangible evidence that could be used for judicial purposes after a crime has taken place. Detection aspects may include operational methods, such as on-site security teams, whereas physical processes might consist of CCTV cameras, security lights and access control systems.

Delaying action

An audio warning can be issued if attempted entry, vandalism, or theft is detected either by the physical or operational detection methods employed. This can be done automatically or by the on-site security team. Either way it should encourage intruders to leave. If intruders ignore these warnings, then implemented access control can be used to lock and secure any additional entry points.

Quick exit can be prevented by securing the gates. It also gives time for the police to arrive on-site, who should be notified as soon as the attempted entry is identified. In most instances, an audio warning is enough to prompt would-be intruders to leave the site. However, with CCTV, any intruders that refuse to go will be tracked and monitored.

Quick response

The final aspect of construction site security is ensuring a quick response from the police or the on-site security team. Remote monitoring services such as CCTV allow operators to report on live situations as they occur. This can encourage a prompt response from the police. High-quality imaging provides irrefutable evidence should a prosecution follow.

Comprehensive construction site security

At Tag Systems, we are experienced at providing comprehensive security systems for construction sites. Our security systems work on the four-fold approach outlined above and contain a range of measures that provide high levels of deterrence against theft and vandalism.

Should the worst happen, our systems facilitate a swift response that can limit the damage and, in some cases, secure a prosecution and gain redress. Our approach begins with a thorough risk assessment and combines regular maintenance.

Wireless installation offers complete flexibility, and 24-hour remote monitoring at our secure operating centre combines to deliver real benefits to construction sites. A coherent security system gives operators and those working on-site absolute confidence in their security, ensuring that losses are minimised and reducing the risk of lengthy delays.
