West Central Ag Services Facility Expansions – Ulen & Beltrami, MN

Co-op adds 6.2 million bushels of storage on two sites and installs Geometrica's Agridome at Beltrami location

The owner wanted to maximize additional storage on two existing sites, integrating new storage with existing distribution, reclaim and shipping systems.

West Central Ag selected Walt Johnson Construction and Crane Service and Braseth Sales and Construction as contractors. VAA provided full-site civil for the Beltrami site and structural engineering and general arrangement design for both facilities.


To complete both facilities before harvest, the design-build contractor / engineering team aligned existing and incorporated new equipment to comprise a cohesive system in five months.

Using point cloud data to model exact “as-built” drawings allowed the VAA team to add equipment and structures without interferences for Ulen. VAA’s engineers provided two cost-effective designs used to solicit bids and the firm worked directly with the contractors to develop construction documents and coordinate soil correction methods for each project.


At Ulen, three corrugated steel storage tanks were added, and the existing pits can transfer grain to the new storage. Two 50,000 BPH screeners were also added, allowing the facility to clean dirty grain, or core a bin, to maintain loading at 60,000 BPH and reduce railcar loading time.

At Beltrami, a 2.6 million-bushel center aeration ground pile, 1.6 million bushels of upright steel storage, two 20,000 BPH truck-receiving pits, and inbound and outbound truck scales were added. The site was designed for future wet holding and drying capabilities and a future dry storage addition. The co-op added 6.2 million bushels of storage in one season for the two sites.

In late 2020 the addition of Geometrica's Agridome at the Beltrami facility converted the temporary ground pile pad into a permanent structure for all-season weather protection and long-term grain storage. VAA prepared general arrangement drawings and provided structural engineering for the dome's foundation and new reclaim tunnel.
