BKBM Professional Engineers was retained the Minneapolis Community Development Agency to prepare a feasibility study for the Shubert Theater. That study included a condition survey of the structural integrity of the theater. To investigate the unique characteristics of the existing structure, BKBM used the impact-echo method of nondestructive testing for concrete and masonry.
The information obtained from this testing was used in the preparation to relocate the 5,816,000 pound building. The undertaking is now recorded as the Guinness Book of World Records largest building moved on rubber-wheeled dollies.
