What Magnum does
Magnum, Inc. is a privately held, family-owned general contractor founded in 1969 and headquartered in Warminster, Pennsylvania. The company delivers three core services: General Construction (full-scope project management from groundbreaking through delivery), Construction Management (professional oversight and coordination), and Design/Build (integrated design-construction delivery leveraging a partnership with Star Building Systems for pre-engineered building systems). Magnum serves primarily federal, state, and municipal government clients across the Philadelphia metropolitan area and the broader Pennsylvania/New Jersey/Delaware region, with a named client roster that includes the U.S. Navy, U.S. Army Corps of Engineers, GSA, FAA, State of Pennsylvania, City of Philadelphia, SEPTA, Penn State, and the School District of Philadelphia, among others.
The business operates a traditional construction-services model: projects are acquired through competitive bidding or direct negotiation with government procurement officers, and revenue is generated via lump-sum fixed-price contracts, cost-plus arrangements, and professional services fees on a per-project basis. Underlying technology is conventional — design-bid-build and design-build delivery methods supported by a 250+ subcontractor and supplier network and a union-trained workforce. The company employs 11–50 people, with leadership concentrated in the Rongione family (Vincent Rongione III as President since 1988, Michael Rongione as Vice President), and has completed more than 500 projects across facility types including military installations, federal courthouses, training facilities, dormitories, hospitals, libraries, and schools. Revenue is not publicly disclosed and the firm has no institutional investors, no subsidiaries, and no disclosed M&A activity.
