This document presents work flow diagrams focused on two of the major tasks provided by the RF Design Department:

1) New cell site design

2) Engineering changes to existing sites.Many other departments, of course, are integral part of these processes and the interaction with them is detailed.

Key:

Introduction

NEPA = National Environmental Policy Act. Requires government agencies (Cingular via FCC) to study if any impact on

wetlands, floodplanes, historical areas, native american territory, etc)

SHIPO = State Historic Preservation Office. (They look for impact and visibility of towers from historic areas)

ASTM = American Society for Testing and Materials (Organization that sets hazardous materials handling standards. Report

documents risk level of litigation and possible financial burdens for a particular property)
