BROOKLYN - One day after a five-story building collapsed in Brighton Beach, resulting in the death of a construction worker, officials are starting to hand out violations to the company in charge of the site. Contractors spent the day today removing debris from the sidewalk outside 2929 Brighton 5th St. where four workers got hurt yesterday and a fifth man died from a heart attack caused by the collapse. The victims' names have not been released yet.Meanwhile, investigators from the Department of Buildings (DOB) and the FDNY have been trying to determine what caused the deadly collapse. A preliminary report shows that concrete had been improperly poured from the third floor down to the second instead of starting from the ground up.Officials have since handed SP&K Construction nine violations for a defective fence, missing guardrails and lack of netting in case of a fall, among other things. The DOB says construction accidents are down 30 percent this year compared to this time last year.
