Plan your lay down area for delivery and storage of equipment. You may have a marked “area” supplied by the client but you should mark on the ground exactly where deliveries are to be placed.
Record and track all items in the lay down area (when delivered and when used).
Remember to allow for security fencing and possibly guards if the area is accessible.
People often think about security for the larger or more valuable equipment but often forget that it is the small, easy to carry, things that go missing and don’t get noticed until later when they are needed.
