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.
