In 2017, Berggren Architects, along with a professional conservator, performed a CAP Assessment (Collections Assessment for Preservation) for the Black Hills Mining Museum in Lead, South Dakota. The original building was built in 1922 but was partially rebuilt in 1956 before the museum owned it. The Black Hills Mining Museum has a unique place within this community of cultural institutions; its exhibits provide a personal, educational experience through its exhibits and tours, built by local miners with an intimate knowledge of technology’s history in the mines. The exhibits illustrate advances in drilling technology and methodology, as well as lighting, ventilation, and safety. Working with the executive board, staff, and volunteers, Berggren Architects created a list of short-term, medium-term, and long-term goals to help the building perform better for the public and as a curatorial space.
