A look at 106 general contractors building in Pittsburgh

Business Journals

30-05-2025

The largest contractors in Pittsburgh employ more than 13,000 locally and had construction-related local billings of $10.1 billion in 2024. Firms have local offices in Allegheny, Armstrong, Beaver, Butler, Fayette, Lawrence, Washington and Westmoreland counties.
The online version of this ranking expands beyond what appears in print; another 60-plus firms are included in our digital rankings, in addition to the 40 featured in this week's print edition.
This week's List is part of a shift in our research methodology and philosophy in 2025, one that will emphasize more data and context for readers while better coordinating the resources available to us and our 46 sister publications under the American City Business Journals flag. We anticipate this effort will identify thousands of new local records — and cumulatively, tens of thousands of new businesses across ACBJ's footprint — this year alone.
Information on The List was obtained through Pittsburgh Business Times research or supplied by individual firms through questionnaires that PBT could not independently verify. In case of ties, firms are ranked by total employment and then listed alphabetically if ties remain. Additionally, companies that did not respond to employment surveys but were still included on this year's List are sorted by estimated total employment figures derived from PBT archives; annual filings with the U.S. Department of Labor; and other firm-specific resources. Inclusion on this year's List required each firm to have a minimum of 60 total employees, using the methodologies described above.
