Breaking Ground

Yolanda Chen

The past month has been an absolute whirlwind. We cut into the concrete floor of the existing building, dug out a massive amount of dirt, and poured all of our footings and foundations for the new building and the climbing walls.

While we were busy cutting rebar, tying steel together, and pouring load after load of concrete, the metal building components were being fabricated and the final engineering of the climbing wall was completed. The steel for the new 57 foot high building will arrive early next month!

Enjoy the latest video that captures some of the fun we have been having this past month!
