Construction Site Security

Responsive and Experienced, 24/7 Construction Security Services

Cambridge Security provides a comprehensive range of construction site security services. A private security company with more than 30 years of experience, we work with clients to create a highly visible and multi-layered security presence at their construction sites.

Construction sites pose many challenges because of the significant quantity of materials and equipment and the vast amounts of space that must be secured. There are often multiple entry points to a construction site, with workers, contractors, and delivery people coming and going on a continuous basis. Building materials and equipment are flowing in and out, which can also present problems.

Let one of our construction security experts come out and conduct a site survey risk analysis, at no charge.


Our construction site security specialists are here to help you protect your site from unwanted visitors, vandalism, and theft—both internal and external. We develop and implement security plans that provide the most effective solutions for your needs. They will include a combination of the following:

Armed and unarmed security officers

Common sense deterrents like perimeter fencing, elimination of unnecessary access points, facility lighting for overnight hours, and secure storage practices

Access control protocols that foster a more orderly, secure site, and a safer work environment for contractors, subcontractors, and the general public

Fire watch services, including the documentation of all fire watch patrols in accordance with state requirements

Guard tracking systems

Fire safety directors

Security technology solutions for 24/7 CCTV surveillance monitoring and remote video monitoring

Mobile patrols

Undercover security officers to reduce theft

Visitor lists and contractor lists, detailing who is onsite at all times

Daily activity reports
