The first step in creating a construction site security plan is to identify the existing security measures that are currently in place. This includes the security procedures currently being followed and the equipment that is being used to help protect the site. Regardless of how well the security measures worked in the past, it is important that you reassess them at the start of every project to see if any changes are needed. You can create a security checklist for your site to help you identify the various security measures currently in place.
