Gas Pipeline Design

Halff supports natural gas transmission and distribution projects with full-service engineering, permitting and construction support. We help operators expand, relocate and maintain pipelines with a focus on constructability, safety and operational continuity.

Whether supporting roadway expansions, utility conflicts, new distribution systems or new field development, our team delivers pipeline solutions that are constructible, field-proven and responsive to real-world site conditions. Halff’s multidisciplinary approach integrates civil, environmental, mechanical and utility engineering with surveying, SUE/Utility Coordination, permitting and geospatial mapping services.

Our pipeline design services include:

• • Routing studies and alignment optimization with GIS and lidar
  • Horizontal directional drilling (HDD) and bore profile design
  • Valve spacing, pig launcher/receiver design and tie-in plans
  • Stress analysis, purge procedures and welding plans
  • Stormwater Pollution Prevention Plans (SWPPP) and permitting packages
  • Subsurface Utility Engineering (SUE) and high-accuracy surveying
  • Field verification, make-ready plans and as-built documentation

We support pipeline projects in both new field development and public infrastructure relocation environments.
