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.
