Strong in Every Direction

McCrossin’s “Strong in Every Direction” video showcases our multifaceted capabilities and unwavering commitment to excellence. Highlighting our diverse range of services, McCrossin stands poised to meet and exceed the evolving needs of our clients in every direction.

Our Rich Heritage

Established in 1951

McCrossin has a storied history that began in 1951 as a general contractor with a focus on small commercial projects. Over the years, our commitment to quality and precision laid the foundation for our transformation into a major construction company.

Penn State Legacy

Our journey started with the construction of key components of Penn State’s infrastructure. Notably, McCrossin played a pivotal role in shaping the University’s Park campus, with one of our earliest projects being the construction of a Hen Barn. The historic link between McCrossin and Penn State continues to this day.

Beaver Stadium Relocation

One of our most notable achievements was the relocation of Beaver Stadium from its original site to its current iconic location. In a groundbreaking project, the 30,000-seat stadium was dismantled, carefully moved, and then reassembled and expanded to accommodate 46,284 seats. Completed in 1960, the project not only solidified Beaver Stadium’s place in history but also showcased McCrossin’s expertise in handling complex and large-scale endeavors.

Evolution with Innovation

Fast-forward to the present, and McCrossin stands at the forefront of construction innovation and technology. We have embraced digital construction capabilities that allow us to efficiently fabricate key components in our state-of-the-art facilities. This approach enables us to ship pre-assembled structures to the site, streamlining the construction process.

Modular Construction Expertise

In response to the changing landscape of construction, McCrossin has embraced modular construction as the new normal. Our world-class mechanical, structural, and electrical shop positions us to execute projects with unparalleled excellence. The ability to prefabricate elements in a controlled environment not only ensures quality but also enhances the efficiency of on-site assembly.

BIM Technology Integration

Our commitment to seamless project execution is further exemplified through Building Information Modeling (BIM) technology. This integration connects our engineering team with the execution teams, fostering smooth communication from the design phase to the construction environment. McCrossin’s adoption of cutting-edge technologies reflects our dedication to staying ahead of industry trends and providing our clients with innovative solutions.

Building a Legacy

As we continue to build on our legacy, McCrossin remains a symbol of reliability, innovation, and excellence in the construction industry. Our history is not just a chronicle of the past; it is a demonstration of our enduring commitment to shaping the future of construction. Over the years we have won many awards and received many honors.  As testament to this, we have been highly ranked in the Engineering News Record (ENR) for many years.

McCrossin has built over 7,600 construction projects that total over 1 billion dollars of sales. With a proven track record of excellence, McCrossin continues to redefine industry standards, delivering exceptional construction solutions that surpass client expectations and make McCrossin a name you can trust.

Though we are ever conscientious of remaining on-schedule, it is never at the cost of safety. The finest craftsmanship, skill, experience, and design are not worth the expense of unsafe practices or preventable injury.

We make an industry-wide effort to avoid injury, and we regularly offer on-site training for various types of hazards that workers may come in contact with. We are vigilant in inviting OSHA and private safety consultants to review our safety program and job sites to provide feedback and improvements.
