Former city hall building demolished
As of today, the former city hall is mostly a memory. Crews began physically demoing the building Monday. If you've driven by, you may see them knocking over walls.
While demolition is most visible this week, preparations have been happening for several months. All of the regulated materials were removed before the demolition began. This included some asbestos materials, which had become friable, and items like fluorescent lamps, which contain hazardous materials. An environmental contractor removed these materials, under the guidance of environmental engineers from WSB & Associates. The hazardous materials were sent to regulated landfills, and the building was inspected twice by WSB environmental engineers before the structural demolition began.
WSB also has observers on site during demolition to make sure that all debris is properly removed from the hole and to ensure that materials are sorted and properly disposed of and that backfill material is of the proper quality and is compacted.
The city's demolition contractor, Frattalone Cos. of St. Paul, has been in business since 1970 and is one of the larger demolition and grading contractors in the region. Frattalone will be responsible for filling the site, compacting and bringing the hole to grade. All this work is anticipated to be completed by the end of the year. See photos from the demolition.
If you're curious what will happen to the site after demolition, the city is seeking proposals from the development community for this lot, as well as a site along the Minnesota River. Proposals are due Jan. 5, 2018, and the City Council should see final proposals by spring 2018.
