Featured projects
Infrastructure
CSX Camden Street
In downtown Baltimore, increased flooding and impacted train operations led to a complete replacement of a storm drainage system, steps away from Oriole Park at Camden Yards and the Baltimore Convention Center. Keller provided a design-build grouting program for an excavation.
Infrastructure
26th Street Emergency Repairs
Our team responded to the emergency quickly and began work within days of the collapse. We found the optimal solution that reduced impact to the surrounding neighborhood and railroad track.
Residential
Robinson Landing
Keller constructed a TRD earth retention system on time and with minimal movement.
Infrastructure
Parallel Thimble Shoals Tunnel
Keller’s performance and expertise were key to providing deep foundations and excavation support for the area’s first bored transportation tunnel.
