Recently, our team volunteered with the Building Trades Employers’ Association Northeast Women’s Group at Cradles to Crayons, spending the day cleaning and sorting shoes for children and young adults. We’re proud to support an organization that provides essential items to families in need and grateful for the chance to give back alongside so many inspiring women in our industry. Thank you to BTEA for organizing a wonderful event!

Project Update 🚧 Recently at a new research and development campus in Massachusetts, our team completed a precision rigging operation that included air source heat pumps, silencers, exhaust stacks, and a large AHU. From logistics to lift, the process was executed safely and efficiently. Another great milestone on a standout project. Shoutout to everyone on our team who helped make it happen! #Rigging #Construction #MEP #MechanicalContractor #ProudToBeTGG #HVAC

We had a great time hosting students from Whittier Regional Vocational Technical High School at our Fab Shop. They got an up-close look at how prefabrication works and learned how it supports safer, faster, and more efficient job sites. It's always exciting to show the next generation what the trades are all about. Thank you to Shawn Guertin, Mike Betts, and Harry Cwik for leading the tour and sharing your expertise. #FabShopTour #TGG #ProudToBeTGG

Safety Tip 🚧 Busy job sites can pose serious risks without clear traffic flow. Creating a construction traffic management plan and making sure everyone knows the routes, walkways, and crossings is essential to keeping workers safe. Let’s work together to stay alert and organized. 👷♀️🗺️✅ #SafetyFirst #JobsiteSafety #ConstructionTrafficPlan #StayAlert #TGGSafety
