Environmental Demolition Former St. Mary’s Hospital

ATON was retained by Farmer Holding Company to assist with assessment, abatement, demolition, and redevelopment of the former St. Mary’s Hospital in Jefferson City Missouri.

Completed: 2019


The former St. Mary’s Hospital was built in phases dating back to 1903. Due to the buildings age, asbestos-containing materials (ACM) as well as other regulated building materials were present in the structure. ATON prepared an application to the Missouri Department of Natural Resources (MDNR) Brownfield/Voluntary Cleanup Program (BVCP) and the Missouri Department of Economic Development (DED) for brownfield tax credits to fund the cost of pre-demolition removal of the asbestos and other hazardous building materials, as well as an underground storage tank.


ATON successfully assisted Farmer Holding Company in obtaining over $1M in brownfield tax credits to cover the cost of asbestos and other regulated building materials abatement. Prior to the start of demolition, ATON conducted a regulated building materials inspection and prepared a final report to be used as guide to abatement. ATON also prepared a demolition scope of work and bid document, including a scope of work for the deconstruction of the historic portion of the original hospital building façade for use in the new construction of a hotel onsite. During abatement, ATON performed oversight of the asbestos abatement contractor, collected air samples for asbestos, performed post-abatement final clearance inspections, collected final clearance asbestos air samples and ensured that all other regulated wastes were properly removed and disposed.


The former St. Mary’s Hospital was successfully demolished to grade and all regulated building materials were properly removed and disposed, leaving the site ready for future development as a hotel with commercial office space and a retail center.
