     Gregori Construction Inc. is a family-owned and run Heavy and Highway construction company based in western Pennsylvania, with a branch construction office in Titusville, FL.  The company was started in 1989 by Richard Gregori, after many years working as a Project Manager and Superintendent for John F. Casey Company.  Having started on a streambank clearing project valued at $15,000, Gregori Construction has grown to be a very capable contractor.

The vast majority of Gregori Construction's customers are government agencies.  Such agencies include local municipalities, cities and counties.  Gregori Construction also has a long and successful history working with the US Army Corps of Engineers, the US Veterans' Administration, the US Department of Energy, and the Pennsylvania Department of Transportation.  In addition to these governmental agencies, Gregori Construction routinely works with the Norfolk Southern Corporation (Norfolk Southern Railway) and Duquesne Light.

Over the course of our history, Gregori Construction has successfully completed work in many phases of the Heavy and Highway construction industry.  Work routinely constructed by Gregori includes (but is not limited to):

  • Bridge Repair / Construction
  • Stormwater Drainage System Repair / Installation
  • Excavation (All Types)
  • Roadway Repair / Construction
  • Erosion Control and Repair
  • Baffle Box Installation
  • Concrete (Vertical and Flat)
  • Structural Steel Erection
Gregori Construction is fully insured and licensed to work in the states of Pennsylvania, West Virginia and Florida.  In 2005 a permanent branch office in Florida was established by Andrew Gregori, who holds Certified General Contractor and Certified Utility Contractor licenses with the FL State Contractors' Industry Licensing Board.

We have enjoyed building many great relationships over the course of our company's history, not only with the various owners for whom we have worked but with our subcontractors and suppliers as well.  We place very high values on integrity, honesty and customer service.  As we complete our 25th year of business, we are eager to service our existing customers as we have in the past and towards meeting and growing with new customers and markets.
