Swiderski Equipment in Antigo held their open house recently and they held it in an addition we built for them last fall. The 70' x 120' x 28' building addition was produced from Butler Manufacturing which has a plant in Evansville, WI. The building features a 7 1/2 ton overhead crane as well as (3) large overhead doors. Because this building is taller than the existing building it was added on to, we had to reinforce the existing roof structure to support the additional snow load.
