Energy Infrastructure Services

JMT performed structural engineering, surveying, and subsurface utility engineering services for a large natural gas pipeline project.


Southeast PA


Energy Owner/Operator



JMT’s licensed professionals, field personnel, and support staff performed various engineering, surveying, and subsurface utility engineering (SUE) tasks to aid in design and construction of a large project in Pennsylvania and Delaware. The natural gas infrastructure scope included repurposing miles of pipeline, constructing several miles of new pipeline, and designing and building new compressor stations, along with miscellaneous facility and meter station upgrades.

JMT performed topographic survey work for permitting for a new driveway access, provided field survey to aid in the planning and permitting of the Erosion and Sediment Control General Permit (ESCGP) environmental permit, surveyed all overhead and some underground utilities, surveyed existing site features at various construction sites, and set control for construction and surveyed various environmental testing locations. The survey crew also supported the SUE crew, which located underground utilities on various sites and for the mainline. The team located bridge pier foundations to ensure the alignment would not impact them. Ground penetrating radar (GPR) was employed to locate underground gas piping and electrical conduit prior to final site civil design.

JMT’s team of structural engineers used geotechnical reports and design input to design the structural foundations for compressor buildings and compressor related equipment. The team also provided input on the design of valve thrust blocks. An SOE was utilized to temporarily shore excavation near a regional rail line for the pipeline construction. JMT’s engineers provided the shoring design for submission to the railroad.
