Whether it be arson, vandalism, or theft, construction sites are prime targets for criminal acts. These events can create significant added costs, including insurance deductibles and consequential premium hikes; work delays; and replacement of lost equipment, tools, and building materials. Such an event can also affect your overall job site and your client's deadline.
Job site security tips
-
Research the work area prior to beginning a job. Carefully researching unfamiliar work areas is especially important if you're not planning to hire on-site security, but should be done regardless. The local police or sheriff department can tell you if a particular area has a high crime rate and may be able to send a patrol to check your site periodically once work begins. You might additionally ask friendly competitors if they've had problems in a particular area.
-
Ensure the job site is well-lit and fenced. Most thieves and vandals will think twice before acting if they have to climb or cut a fence and perform their activity without the protection of darkness. Motion-detector lights and lights with infrared triggers illuminate with movement, which can scare off intruders and alert neighboring businesses or homes. Most experts recommend a chain-link fence since it provides enclosure while allowing visibility, but if fencing isn't in the budget, designate enclosed storage areas for tools, materials, hazardous items, and flammables.
-
Implement an inventory system for all tools and equipment. Keeping a running inventory helps you track what's on site. Smaller tools that are easy to carry are often targeted by thieves. Assign the site foreman or supervisor to log when a tool is checked out, who is using it, and when it's returned. Consider etching a serial number on equipment that lacks distinguishing marks, and put your company's logo or name on expensive items.
-
Consider installing ignition cutout switches and GPS. You can immobilize heavy vehicles and machinery by installing ignition cutout switches. GPS units are a good consideration for expensive heavy equipment, providing location alerts and notifications if equipment moves outside a designated area.
-
Security, be it real or faux. A security camera can be a visual deterrent and can help identify brazen thieves or recover stolen items. A security guard and/or guard dog increases on-site protection, and there are electronic devices that simulate a barking dog to create the illusion of a guard animal. Whether or not you actually have surveillance or guards, post warning signs as if you do.
-
Control access points to the work site. Whenever possible, limit the site to a single entry and exit point. Each additional access point increases the difficulty of monitoring who comes and goes. You might also consider asking employees to park off-site to reduce traffic near equipment and materials.
-
Plan out deliveries and installations. Items like HVAC systems, plywood, windows, and doors often arrive days or weeks before installation. Since these materials become bigger targets the longer they sit unattended, either install them promptly, store them in a secure enclosed area, or schedule deliveries as close to installation time as possible.
-
Have a lock-up procedure in place. Designate employees responsible for end-of-day lock-up, including ensuring supplies are secured in their designed area, vehicles are locked and key-less, and oil and gas tank caps are locked.
-
Involve the community. Ask nearby residents and businesses to keep an eye out for suspicious activity during non-work hours and to report concerns to you or local law enforcement.

Frequently Asked Questions
What should I do first when planning security for a new job site?
Start by researching the local area and contacting law enforcement for crime information and possible patrol support, then plan fencing, lighting, and secure storage based on that risk.
Are temporary fences and signage effective deterrents?
Yes; visible barriers and warning signs increase the effort and risk for intruders and often deter opportunistic theft and vandalism.
How can I track small tools that are frequently moved?
Use a check-out log managed by a supervisor, permanently mark tools with identifying information, and keep high-value small tools in locked storage when not in use.
