Metrodome demolition work has been suspended "for a few days" while Mortenson Construction investigates the unplanned drop of a ring beam earlier this week, the Minnesota Vikings confirmed Wednesday.
No one was injured in Monday's incident, as the beam and debris fell within a specified safety zone.
Mortenson Construction said crews from a demolition subcontractor were bringing down a section of ring beam on the northeast side of the Metrodome when an adjacent section came down out of sequence.
At Wednesday morning's Minnesota Sports Facilities Authority meeting, Mortenson said excavation work at the stadium site is 30 percent complete, with 250,000 cubic yards of dirt removed.
