Our client
This client’s bulk storage terminal facility at a major U.S. port needed additional storage capacity for coal. The existing yard was at capacity and the only space available for expansion was a brownfield former synthetic fuel plant site adjacent to the yard.
Project highlights
Their challenge
The available expansion area was irregularly shaped, with a rail line on one side and an existing transformer and maintenance building on the other. The storage area was further minimized by the need to extend an access road and concrete drainage ditch around the new storage area. Various underground utilities had to be identified and either abandoned or relocated, and the local municipality had a rigorous construction permitting process. Salas O’Brien was engaged to provide engineering and design services for this 100,000-ton storage expansion.
Our solution
Civil site-work included demolition, grading, drainage, relocation and extension of underground utilities, and volumetric calculations to confirm the area could accommodate the required volume within permit limitations. Our engineers designed the access roadway and drainage ditch to maximize available storage area while maintaining required rail line clearances. A concrete wall was also designed to shield the existing transformer and maintenance building from coal handling operations and increase the storage area. Grading around the new feeders was designed to minimize water intrusion into the reclaim tunnels.
The results
Our team collaborated to maximize the available expansion space and ensure existing underground utilities were properly managed. We also coordinated with local municipal authorities to compile a storm water narrative, erosion control plan, and water quality data to satisfy construction permitting requirements in a timely manner so that the construction schedule was not impacted.
