Construction Safety Week is a reminder of what matters most on every jobsite and in the office. This year’s theme, All In Together, reflects how safety is achieved across every phase of work.

It requires commitment at every level, from planning through field ex*****on, to recognize hazards early and make informed decisions before work begins. Safety is not separate from the work. It is built into how projects are planned, coordinated, and carried out day to day.

The focus remains the same across every site and every team: ensuring that everyone goes home safely, in both the office and the field.

We had the best day celebrating Take Your Child to Work Day 2026 at TRINITY! 💙🎨

We welcomed some new faces and loved seeing so many familiar ones back again. It was especially meaningful watching our employees’ kids build relationships and connect the same way we do every day.

From a safety presentation to painting pots and planting their own plants, building structures and birdhouses with popsicle sticks, striking a pose at the photobooth, and diving into arts and crafts, the day was full of hands-on fun and creativity.

Thank you to everyone who joined us and helped make the day so memorable. We loved seeing your kids explore, create, and experience the kind of culture we’re proud to build at TGC!
