As inherently hazardous environments, unauthorised access on construction sites can lead to severe consequences – not just for the trespassers but also for workers and the broader community. Beyond the significant financial losses from theft and vandalism, trespassing incidents can also result in serious injuries or even fatalities.
Find out more about the impacts trespassers can have on a construction site and what you can do to prevent them in this week’s blog.
The hidden dangers of trespassing
While theft remains a pressing concern, the risks associated with trespassing extend far beyond stolen tools or materials. Very recently, a tragic incident occurred when a man gained unauthorised access to a Willmott Dixon site at Manchester Science Park and fell from a crane, resulting in his death. Such events underscore how crucial it is to take every possible action to keep construction sites secure and prevent unauthorised entry.
Moreover, trespassers can inadvertently cause damage to equipment, disrupt ongoing work or even pose threats to on-site personnel. The presence of unauthorised individuals can also lead to project delays, increased insurance premiums and potential legal liabilities.
The financial impact
Theft and vandalism continue to plague the construction industry, with annual losses estimated at £800 million in the UK. A survey by the Chartered Institute of Building revealed that 92% of construction professionals have experienced theft on their sites. These crimes not only result in direct financial losses from stolen equipment or materials but can also disrupt project timelines, leading to further financial impacts as work and payments from clients become subject to delays.
Five ways to keep your site secure
To mitigate the risks associated with trespassing, consider implementing the following security measures:
- Illuminate the site: Ensure that all areas of the site are well-lit, especially during darker months. Motion-activated lighting can deter unauthorised individuals and alert security personnel to potential intrusions.
- Secure equipment and materials: Lock away tools, machinery, and materials when not in use. Use tamper-resistant locks and store valuable items in secure containers or designated storage areas.
- Establish a robust perimeter: Erect sturdy fencing around the site, complemented by clear signage indicating restricted access and the potential safety and legal consequences for trespassing.
- Implement surveillance systems: Install CCTV cameras at strategic points around the site. Modern systems offer real-time monitoring and can be integrated with alarm systems to alert authorities promptly.
- Engage professional security services: Hiring SIA-accredited security personnel can provide an added layer of protection, ensuring rapid response to any unauthorised access and maintaining a visible deterrent to potential trespassers.
Remember, keeping trespassers out isn’t just about protecting property – it can be about safeguarding lives!
