Project Overview

• Repairs completed below active roadway
• Complicated access due to extensive utility infrastructure

A natural gas power plant on the East Coast identified spalling on the walls of six underground concrete tunnels, posing potential risks to both structural integrity and operational efficiency. As a leader in concrete repair, STRUCTURAL was contracted for the project.

The project presented several unique challenges. The tunnels, located beneath an active roadway, housed electrical lines, complicating access due to the extensive utility infrastructure. Frequent flooding required meticulous coordination with the dewatering schedule, and logistical constraints made lowering equipment into the underground space particularly tricky.

To navigate these obstacles, the team developed a comprehensive pre-planning strategy to ensure the highest level of safety and quality. The tunnels were restored to optimal condition, with the project completed both on schedule and within budget.
