We recently welcomed students from Whittier Tech to our Fab Shop for a behind-the-scenes look at prefabrication in action. They explored the process firsthand and learned how it helps improve safety, efficiency, and productivity on the job site.

A big thank you to Shawn Guertin, Dan McCarthy, and Harry Cwik for taking the time to mentor, educate, and inspire the next generation of trades professionals.

Safety Tip 🚧

A safe jobsite depends on everyone knowing their roles. Competent persons have the authority to identify hazards and correct unsafe conditions, while qualified persons bring specialized training and expertise to critical tasks. Make sure your crew knows who to contact before work begins. 👷🚧

Examples of qualified persons include welders, riggers, and MEWP trainers, while competent persons may include foremen, supervisors, and safety representatives.

Recently, our newest hires and co-ops had the opportunity to tour all three of TG Gallagher’s fabrication facilities.

This experience offered a firsthand look at our day-to-day fabrication operations and helped demonstrate how each role contributes to the success of our projects.

A big thank you to Harry, our Fabrication Manager, for sharing his expertise and helping our future leaders build a strong foundation from day one!

Project Update 🚧

The new Fieldhouse at the Boys & Girls Clubs of Dorchester is taking shape. TG Gallagher has successfully completed all underground plumbing and Trimble layout work and has roughed in all three trades on Level 2. With that work complete, the team has started rough-ins on Level 3 for all trades and is continuing to make steady progress.

Thank you to our crews and project partners for helping keep this project moving forward safely and efficiently.
