The renovation of the old Harrington and Story warehouse at 212 South Wallace Avenue in Bozeman has been no ordinary task. In the 1900s the property used to be the Chicago, Milwaukee Co. East Main Depot where asbestos ore was stored for milling prior to being transported elsewhere. Since then, anthophyllite asbestos contaminants have been found in the soils on the site and on surrounding private property where asbestos ore was spread or used as fill. Extensive abatement and clean-up of the soils along South Wallace was performed in 2003 and 2009. Further clean-up was performed in 2014 prior to the demolition of the old warehouse and remodeling of the site. Although the process of removing the asbestos took longer than originally planned, the transformation was worth it.
The old historic structure was a combination of heavy timber beam and column floor construction to hold large commercial loading at the ground level, and light-frame wood stud construction at the upper levels. The roof trusses span 60 feet, and have no interior supports. The total building area of the remodel is approximately 18,600 square feet (1,723 square meters). The renovation project was built by general contractor Langlas & Associates with architectural design by Intrinsik Architecture and Nishkian Monks serving as structural engineers of record. Since the building went through a complete renovation from top to bottom, the City of Bozeman Building Department required that the structure be analyzed and proven to meet the performance requirement of the current building code. The structural scope of services, as performed by Nishkian Monks, included engineering of new window openings in exterior walls; analyzing and strengthening of existing lateral system to meet current code requirements; removing 1/3 of existing structural columns and introducing new load path to remaining or new columns to provide increased flexibility for future tenants; analyzing existing roof trusses for new loads and fixing damaged truss web members; adding a new elevator shaft and two new stair towers; and adding concrete exterior light-well, patio, and ramps.
