For this month's Thumbs Up Thursday, we had the time of our lives with a competitive game of Water Pong!

And no, these photos aren't from an old-school college party. They were taken right in our office garage!
It was a great way to unwind, share some laughs, and enjoy a little friendly competition.

Congratulations to this year's Water Pong champions, Chelsea and Sean! 🏆👏

Every successful infrastructure project starts with accurate data from the field.

Our Survey team provides the precise measurements and site information that engineers rely on for design and construction. Using advanced technology and field expertise, they help define existing conditions and ensure projects are built on a solid foundation of information.

This Infrastructure Week, we recognize the essential role survey professionals play in turning plans into buildable, real-world solutions.

The beautiful spring weather and summer days ahead have us revisiting some of our previous work 🍃

Visitors to Preservation Parks of Delaware County’s (PPD) Emily Traphagen Park can enjoy an enhanced trail experience with the addition of a boardwalk designed to improve accessibility while helping preserve the surrounding wetlands.

CM was proud to partner with PPD by providing structural analysis and design support for the boardwalk foundations, along with bid and construction-phase services throughout the project.

Working alongside Oxbow River & Stream Restoration Inc., which led the wetland design, and Wickcraft Boardwalks, the project team helped deliver a durable solution that supports both environmental stewardship and public access.

From peaceful walks to scenic views, the boardwalk offers visitors another way to experience the natural beauty of Emily Traphagen Park.
