Project Included

Substation Civil Foundation Installation—Marcus Hook, PA


Riggs Distler installed a substation foundation and performed related heavy civil work on behalf of a regional energy company in southeastern Pennsylvania. The new substation will deliver retail-level electricity to residents and businesses throughout the area. Our work included:

  • Erosion control
  • Bulk excavation and backfill
  • Storm water piping
  • Import structural fill
  • Transformer, caisson, and pad foundations
  • Switchgear building foundation
  • Water line service and sanitary holding tank installation
  • Grounding installation
  • Core sampling and testing
  • Yard stone and asphalt pavement installation
  • Transformer containment walls

Challenges Overcome

Advanced planning was necessary to meet the project’s expedited schedule. The new substation is located near an industrial facility, and the foundation work had to be performed in a very limited work area. Concrete foundations and anchor bolts needed to be in precise locations, which our team confirmed thoroughly before proceeding. Foundations also had to be ready for electrical equipment delivery according to the client’s timeline, and efficiency and safety were top concerns. With no room for storage on-site, excavated material was removed from the site and backfill was imported.

Results Delivered

Relying on our industry-leading quality control program, Riggs Distler completed all of the foundations and associated work to the highest possible standard, meeting all client deadlines. The substation when online as scheduled, and the client energy provider was able to deliver more power to their electrical grid. The client was very satisfied with our work, and, as a result, we were subsequently awarded additional heavy civil and concrete projects.
