Civil & Structural Engineering.

Here are a few examples that highlight our Civil & Structural Engineering experience.

Coal Handling System
Varo was retained to perform design and engineering, and specifications design for the upgrade of a coal handling system. The project consisted of modification of structures, access platforms with a caged ladder, and concrete foundations. It also included rail car and truck unloading hoppers, belt conveyors, crushers, vibratory feeders, bucket elevators, dust collections system, screw conveyors, rotary airlocks, electrical controls and programming.

FGD Material Handling System
Varo was retained to perform the structural and mechanical engineering, and furnish the equipment and structural steel as a supplier to the general contractor. The project included a limestone truck dump and 30”, 460 TPH stacking conveyor; two 30”, 345 TPH reclaim and transfer conveyors; two 24”, 100 TPH gypsum transfer conveyors; and a new gypsum radial stacker.

Coal Yard Expansion for High Sulfur Coal
Varo was retained to perform the structural, mechanical, electrical, and controls engineering, and furnish the equipment and structural steel as a supplier to the general contractor. The project included modifications to install a fixed tripper on an existing belt conveyor; three new 42”, 800 TPH belt conveyors; two transfer towers; a 42”, 800 TPH fixed stacker; three gyrating drawdown hoppers and vibratory feeders located in a concrete reclaim pit and tunnel. It also included modifications to the existing Crusher Tower.

Raw Coal Handling System
Varo was retained to perform engineering and design for the upgrade of a raw coal handling system. The system was upgraded and a new direct ship storage and handling system was added to an existing mine. The slope conveyor and raw handling coal system was upgraded to 1800 TPH and a fixed raw coal stacker was added to the system. The direct ship storage system included a new transfer conveyor and a radial stacker for stockpiling. The direct ship reclaim system included a new Stamler reclaim feeder and conveyor to deliver coal to the existing rail loadout. Varo performed all foundation, structural and mechanical engineering for the project.
