Temporary construction fencing in an inexpensive way to deter trespassers from your site but isn’t the only step. Make sure all workers and visitors sign in and out of your site and remind crews to keep an eye out at all times for intruders.
If you are working on a residential project, neighbours can be powerful allies. Introduce yourself, give them your phone number and ask them to call you if they see anything suspicious such as individuals on site at odd hours. At the end of the job, give them a small token of appreciation.
If you have a large site, on-site 24-hour security personnel, security alarms or video monitoring can provide additional protection.
