Sand Screening Facility - Hager City, WI

Facility can load 21 rail cars per day.

VAA was retained by a design-build contractor to provide design and engineering services for the renovation and upgrade of an existing sand screening facility located five miles from the client’s sand mine. The facility operates at 300 tons-per-hour and requires truck receiving and shipping from the mine by rail as well as high-volume drying, scalping, screening and storage features.

To save the client time and money, the remodeled facility was designed to use as many of the structural and mechanical components from the existing facility as possible.

Our Approach

VAA collaborated with the project team on general arrangement and structural engineering as well as delivering shop drawings and a dust collection system duct layout. The main challenge of the new facility was a 92-foot tall screening building housing six large screeners. VAA engineered a solution to minimize heavy vibrations from the screeners to help reduce wear and tear, improve working conditions and ease long-term maintenance costs.

The team also modified existing storage tanks and structural components from the old facility to support storage and conveyors in the new facility.


VAA provided cost-effective design and engineering solutions that used many of the existing facility components, while meeting quality and safety standards for the industry. The team’s efforts allowed the client to get up and running quickly to get into the booming market.
