PPL Corporation - Generation Division

PPL Corporation has retained D’Huy Engineering, Inc. to provide structural design, technical inspections and project management at its power stations in Pennsylvania.

D’Huy managed the annual technical inspections of all civil and structural components at two coal fired power stations and two natural gas peaking power stations in Pennsylvania. The program involved continuous and scheduled inspections and repairs. Destructive and non-destructive examinations were made on steel and concrete coal silos, 60' concrete chimneys, structural steel framing, conveyors, raw water intake structures, underground pipe and structures, hyperbolic cooling towers, supercritical pipe hangers and miscellaneous structures. The results of the inspections contributed to the overall capital improvement program and to schedule maintenance and repair during scheduled outages.

We provided professional structural design and support for numerous capital and repair projects for PPL. Projects were comprised of new and renovation work and range in size from several hundred thousand dollars to several million dollars. Projects included:

  • Warehouse structural design
  • Coal conveyor modifications
  • Steel frame replacement and elevated walkways
  • Ash sump pit replacement
  • Gypsum storage structures and wind screens


D’Huy managed several projects at PPL’s power stations. We had been responsible for developing budget scopes and estimates for the work, assembling teams of in-house designers and consultants to execute design, and oversee construction in the field. Project delivery included, design-build, design-bid-build, and time and material construction. D’Huy also oversaw the execution of multiple smaller projects across the PPL assets using PPL and independently contracted construction forces.
