Black River Dredge Material Reuse Facility – Post Construction
Construction Oversight – Slurry Pipe Installation
Coldwater played a pivotal role in the successful execution of the Black River Dredge Material Reuse Facility (BRDMRF), a cornerstone of the City of Lorain’s environmental restoration initiatives. The project encompassed the construction of north and south solids basins, the water management area, and the assembly of innovative GeoPools to enable the environmentally beneficial reuse of dredged material.
Key Contributions and Achievements
- Construction Administration: As the City’s on-site representative, Coldwater efficiently oversaw all aspects of construction, ensuring seamless collaboration among contractors, the City of Lorain, and regulatory agencies. Our team maintained strict adherence to design specifications and managed project documentation, which minimized delays and secured compliance with all regulatory standards.
- Inspection Services: Conducted daily on-site inspections to monitor work quality, assess contractor performance, and identify and resolve issues promptly. We paid special attention to erosion and sediment control measures, critical infrastructure installation, and environmental protection practices.
- Construction Oversight for Site Development & GeoPool Assembly: We successfully oversaw site grading and the construction of solid basins and water management areas. Our team oversaw the installation of aggregates, underground dewatering pipe systems, and multiple pipe support structures. We ensured that the GeoPool frames and geotextile fabrics were installed accurately according to the design plans.
A legacy steel mill site was the largest available site on the Black River but it presented two major challenges: the acreage was not large enough for traditional sluiceways and the subsurface was contaminated. Coldwater was able to overcome the challenges by using innovative GeoPool structures for more effective use of the available space and by using slag, a steel making byproduct that was plentiful on the site, to build up the bottom grade for the facility.
