Teaching Dairy Barn and Large Animal Teaching Complex
Cornell University, Ithaca, NY

State-of-the-art learning environment

The Harman Group provided structural engineering services for the design of a teaching dairy barn for Cornell University. The facility includes a freestall barn for 200 cows, milking area, classrooms, offices, feed storage and milk and manure holding areas.

The teaching dairy barn at Cornell had to integrate cost, aesthetics and durability in a challenging exterior environment.  The Harman Group worked closely with the Architect to implement a long span plylam mass timber truss system infiltrated with skylights.  These prefabricated plywood trusses were a precursor to cross laminated timbers. Traditional timber purlins were used to span between the trusses. The roof design provided for shading to maximize ventilation through the freestall barn during the summer. The barn can be enclosed with nylon fabric curtains in the colder months.

A milking center with a milking and holding area features a plylam truss system with polycarbonate coverings, and a viewing/classroom space overlooking the milking area.

Special concrete mix designs were developed to resist corrosion from alkali sulfate reactions common to local aggregates.

The facility was awarded LEED certification.
