Southwest Gas Replacement Program

Greater Phoenix Metropolitan Area, Casa Grande and Greater Pinal County, Sierra Vista and Graham County, Arizona

Engineering design services include construction and permitting drawings for gas main abandonment and replacement, new residential and commercial projects, and special projects. Design scope includes engineering services, pipeline installation, replacement and abandonment of distribution and high pressure systems, directional drilling, regulator stations and pressure testing.

Southwest Gas is in the process of upgrading their pipeline systems throughout the state. Bowman has provided construction drawings for over 40 projects in nine months. Designs include steel transmission and distribution main replacement, HDD design, neighborhood grid and service replacement and new development. Services also include providing pressure test construction, tie-in and corrosion protection details, regulator station design, cost estimates and extensive client/city coordination.

Bowman is providing on-call land surveying services in the metro Phoenix area. With approximately 15 projects completed each month, the team has completed over 175 projects to date since signing the contract. Aspects of the program include: Boundary and right-of-way determination, topographic surveys, gas line construction staking and as-builts, field staking of existing and proposed gas line easements and preparation of new easement documents. One of the challenges to this contract are the rigorous schedules often required for survey staff to mobilize anywhere in the metro Phoenix within a 12-hours’ notice.
