Nicholson Construction is reinforcing Eucha Dam with the support of a custom 30T Dymax Rail Cart. The dam supplies critical drinking water to the city of Tulsa. Over time, its foundation began to shift, raising concerns about long-term stability.
Nicholson built a temporary rail system directly into the dam’s crest, anchoring it to the concrete.
A heavy-duty Dymax Rail Cart travels along this track, serving as a mobile drilling platform. Its removable decking system allows crews to drill directly through the surface without repositioning. Stabilizers and a manual parking brake keep it steady during operation.
The 8×24 rail cart is winched into place with an air system and supports a Cat 308 excavator, which helps manage drill pipe extensions. A second cart carries a specialized drill rig that performs the shaft work. Once drilled, the shafts are grouted and capped with steel plates to stabilize the structure.
It’s a long, complex job. Site setup took four months, drilling has been underway for two, and work is expected to continue into early 2026.
They killed a cottonmouth snake on the tracks the other day. The cart wheel cut it in half. Sad — but better than being bitten.
