Site Survey

Site Survey
The site must be carefully inspected or surveyed using appropriate site survey forms
before orders are placed for the equipment.
A technical representative from both the customer and the site owner should preferably be
in attendance for total concurrence at a single given time.
In order to minimize any misunderstandings, which may arise in the future, the survey report should be approved
by all the attendees at the site survey. The site survey should address all relevant issues involving the MTS
site installation. All involved parties should be in agreement on all of the issues before any work commences.
