The survey will be separated into five (5) sections and will be conducted over three (3) years. Two (2) sections will be surveyed in Year 1, one (1) section in Year 2, and two (2) sections in Year 3. GUC shall execute an annual services contract with the selected firm, renewable each year at the discretion of GUC. The GUC natural gas distribution system consists of approximately 760 miles of distribution main and 510 miles commercial, industrial, and domestic services. Mains are generally located within the road right-of-way, however, in some areas the mains may be installed in designated easements or behind houses, alleys, etc. Most meters are located in a readily accessible location on the side, back, or front of the home/business.
