Effective Construction Security Techniques

What security risks are you exposed to on your building sites? How many theft or loss incidents do you have each year? How much do those occurrences set you back? What steps do you take to ensure construction security?

These are crucial questions to ask if you’re a project owner, General Contractor (GC), or Construction Manager (CM). There are not only up-front costs to consider with every act of theft or vandalism, but also the lost time or lost productivity that can ensue.

Security systems and deterrence measures, on the other hand, might be pricey. This article examines the top four security company London options accessible to contractors.

The Importance Of Construction Site Security

Are you curious about the risks associated with construction security? Construction sites are frequently targeted because of the high cost of much of the equipment utilized on-site. Because many modern construction sites are still unsafe, many construction sites provide low-risk, high-reward chances.

To make matters worse, the cost to GCs and CMs doesn’t stop with replacing stolen equipment. It also includes the cost of renting or financing equipment to fill temporary needs and reduce the risk of project delays, as well as lost productivity and time due to missing equipment, time spent on police reports and insurance claims, and the cost of renting or financing equipment to fill temporary needs and mitigate the risk of project delays.

Having a strong construction security policy to protect your sites can help you avoid losses while also increasing the project’s return on investment. Find out more in the sections below.

The Top 4 Security Methods For Construction Sites

The following construction site security methods are meant to be utilized together rather than separately to create a comprehensive security strategy. 

  1. Surveillance by video

Video surveillance systems have gone a long way in recent years. Most modern construction site surveillance solutions now include high-definition footage, 360-degree coverage, alarm systems, infrared lenses or motion lights, and automatic alert systems to detect suspicious conduct, among other features. If properly installed, these modern security systems may provide total site coverage. As a result, these methods improve the possibility of arresting criminals after recovering stolen property. The best part is they don’t jeopardize anyone’s safety. However, they may be less effective than a personal presence on the construction site in preventing crime in the first place.

  1. Security Personnel on-Site

Security guards are common in the construction industry. Though they are rarely employed as a sole security measure, they are a valuable supplement to many construction site security plans. They can often be used for purposes other than site surveillance and patrol. Theft of materials, stealing plans or ideas, protecting labor, damage to the project or property, and keeping things ordered are some of the key hazards that security guards protect construction sites from. The best uses for on-site security officers are:

• Project smaller locations with fewer probable avenues of entry and a smaller perimeter to patrol.

• High-crime areas and locales that may require more deterrence, as physical bodies are generally perceived as scarier than silent (or potentially undetected) deterrence techniques.

• Projects in congested urban areas. If hundreds (or thousands) of persons pass by your workplace daily, a physical deterrence device can help prevent unauthorized access.

  1. Management Systems for Equipment

According to studies, 79 percent of employees will steal from their workplace at least once. It emphasizes the importance of protecting construction enterprises not only from the outside but also from within. The first step in creating an equipment register is to assign a serial number, license plate, or other identifying feature to every item on your construction site. Due to legal requirements, you must register some of these objects, but you can track others with tags by the project owner, GC, or CM (equipment such as impact wrenches, electric nibblers, etc.). After that, someone on-site should be in charge of making sure that all equipment is correctly checked out and checked in. Though equipment registers don’t do much to prevent theft from individuals outside of your personnel, they do result in a concentrated equipment store on your premises. Having most of your equipment in one secure location makes it less accessible to potential thieves, resulting in fewer losses.

Though a registry can be maintained manually, using equipment management software is one of the most effective ways to keep track of your assets. 

  1. Control of Access

Construction access control systems are an underappreciated security feature provided to project owners, general contractors, and construction managers. They connect door strikes, turnstiles, and other entry points to LTE-connected smart devices that validate worker credentials and prohibit untrained or uncertified personnel from entering a job site. It protects the project from potentially hazardous workers and eliminates the possibility of non-compliance-related fines. Also, it completely secures the perimeter of the job site, making it far more difficult for unwelcome visitors to get entry after hours.


The security of a construction site is not something to be taken lightly. Construction security is a notoriously low-margin sector. Therefore owners, general contractors, and construction managers cannot risk any inevitable losses due to theft or damage.
