Ask the proposal to identify the intended perimeter, relevant equipment and dependencies on other contractors. If the site has no confirmed suitable electrical arrangement, raise that before agreement rather than assuming equipment can be connected anywhere. The appropriate professionals need to assess the actual site and proposed installation.
Obtain applicable owner and development approvals before work. Keep the completed installation information with the property records, including changes made as building progresses. If later work affects the fence, arrange the required assessment and documentation rather than treating the original project plan as a record of every future alteration.
