Tonn and Blank has served as an advisor and contractor for Urschel Laboratories since the early 1950s. After undergoing numerous renovations, completed by Tonn and Blank, at their current site, Urschel decided it was time to find a location that would house a new facility and also allow them with future expansion opportunities. The new Urschel Laboratories World Headquarters is a 373,000 state of the art facility located in Chesterton, Indiana. The $80 million dollar facility took 16 months to complete. The building sits on 160 acres which allows Urschel plenty of space for future growth and expansion.
