Our History
A Legacy of Growth, Leadership, and Trust
Founded on a Vision
Jack Mascaro founded the company with a simple goal: bring professionalism, integrity, and trust to the construction industry. Working from a ping pong table in the basement of his home, he launched Mascaro's first project and laid the foundation for what would become The Mascaro Advantage.
Building Momentum
Just two years after opening its doors, Mascaro secured ten projects in a single year and expanded its client roster. The company's reputation for quality and reliability was quickly taking shape.
Relationships That Endure
Major projects for the National Aviary and Heinz Hall marked the beginning of client relationships that continue decades later. These partnerships reflected Mascaro's commitment to collaboration, trust, and long-term success.
Expanding Capabilities
A pivotal year for the company, Mascaro entered the heavy and highway market while moving into its new headquarters in Pittsburgh. The milestone expanded both the firm's capabilities and its capacity for continued growth.
Building Pittsburgh Landmarks
Construction begins on Heinz Field and the UPMC Sports Performance Complex, helping establish Mascaro as a trusted builder of high-profile athletic and community facilities.
Advancing Research, Earning Recognition
Mascaro builds its lab resume in a big way as construction gets underway for the University of Pittsburgh’s Biomedical Science Tower 3, a new 10-story research facility in Oakland. Mascaro wins its first Best Places to Work in PA award, ranging No. 4 out of 50 in the Medium Size Companies.
Growth Across the Region
Mascaro expanded beyond Western Pennsylvania with major healthcare, government, industrial, and infrastructure projects throughout Maryland, Washington, D.C., West Virginia, and beyond. Regional growth was fueled by the same values that shaped the company from the beginning.
The Mascaro Advantage Takes Shape
As the company grew, a culture centered on teamwork, transparency, accountability, and doing the right thing became a defining differentiator. These principles continue to guide every project and relationship.
Building a Greener Future
MCSI is outgrowing its space, and Mascaro begins working on a new facility to provide research and office space. The new home consists of a 20,000-square-foot addition and renovation of 22,000 square feet of existing space in Benedum Hall. The project achieves LEED Gold.
Celebrating 20 Years
Twenty years after its founding, Mascaro celebrated a significant milestone while continuing to deliver larger and more complex projects across multiple markets. The company had grown, but its commitment to people and relationships remained unchanged.
A One-of-a-Kind Sports Record
Mascaro completes BID Package 3A for the CONSOL Energy Center Arena, now known as the PPG Paints Arena. This package included the structural excavation, concrete foundations, and associated dampproofing and waterproofing. Mascaro is the only contractor in the region to have worked on all three professional sports venues.
Fueling a New Industry
The oil and gas industry is about to take off in the tri-state area surrounding Pittsburgh, and Mascaro grabs a piece of it with the civil and foundation package for the Valourec Star Pipe Mill Facility and foundations for a MarkWest Compressor station.
Strategic Expansion
The formation of new business ventures and partnerships expanded Mascaro's reach into specialized markets and emerging industries. The company continued to evolve while remaining focused on delivering exceptional results for clients.
Strengthening the Foundation
Major infrastructure and higher education projects highlighted another successful chapter in Mascaro's history. Recognition as one of the region's top workplaces underscored the company's commitment to both its clients and employees.
