HALLETT DOCK TRANSSHIPMENT FACILITY
Hallett Dock is a multi-modal transshipment facility, accommodating shipping and receiving by rail, truck and ship. Several divisions of Krech Ojard have coordinated their services to complete this project. The Civil Group performed site surveying & site design. The Structural Group designed the new rail car dump facility. The Mechanical Group designed the rail car dump and conveyor systems. North Shore Track Services, a subsidiary of KOA, installed new railroad lines.
Hallett Dock’s location of the rail dump facility provided a unique challenge for our structural engineers: the underground facility is adjacent to a wetland area, twenty feet below the water level. The installation of fifty foot sheet piles formed a coffer dam, allowing the site to be safely excavated. One hundred vertical piles into the silt below, utilizing the friction of the soil against the surface of the piles to anchor the facility into place.
The new structure features a dust collection system that collects and solidifies airborne particles and returns them to the conveying system, reducing both product loss and air pollution.
