TG Gallagher was proud to participate in this year’s JA Inspire Career Fair in Boston, where we connected with over 1,500 8th-grade students exploring future career paths. As a leading mechanical contractor specializing in HVAC, Plumbing, Fire Protection, and Service & Maintenance, we were able to showcase the opportunities within our industry. Students explored hands-on construction work through a VR headset and learned about the rewarding careers that come with building and shaping the world around us. Thank you to Junior Achievement of Boston for hosting such an engaging event. We’re thrilled to play a part in inspiring the next generation! ⭐️⭐️⭐️

Project Update 🚧 After months of thorough preparation and collaboration, we’ve reached a major milestone at FM Globals new 320,000-square-foot research and development facility in Norwood, MA. Our team successfully engineered, prefabricated, and rigged into place multiple risers, including five 50-foot mechanical pipe risers, a 30-foot plumbing riser rack, and sheet metal risers. Each part of this project was carefully planned and executed, ensuring safety and efficiency throughout the process. A big thank you to Bosco Crane Company Inc, Worcester Air Conditioning, LLC, Shawmut Design and Construction, and everyone on our team who contributed to making this happen! 🙌 #Construction #Collaboration #Prefabrication #SafetyFirst #TGGallagher

Another successful rigging in the books! Thank you to our PM, Safety, and field team for your hard work and dedication to getting the job done safely and smoothly!
Prefabrication is central to our team’s innovative approach at FM's new #ShawmutBuilt facility in Norwood, MA—a state-of-the-art, 320,000-square-foot complex designed for next-generation research and development. An example of this approach is the building’s mechanical systems: through more than 70 precisely coordinated crane picks, our team is installing prefabricated air handling units, electrical conduit, geothermal piping, and other essential components that support the facility’s advanced research capabilities. This controlled process ensures rigorous quality assurance, minimizes rework, and reduces material waste, resulting in a faster, safer, and more predictable build with minimal onsite disruptions. This process reflects the meticulous preplanning and collaboration of our team and subcontractor partners—including TG Gallagher, Worcester Air, Bosco Crane, and Gaston Electrical—whose expertise has been instrumental in executing the installation.
