Tamco Construction Corp.

One worker was killed and four others were hospitalized with concussions when a building collapsed on the Upper East Side during construction of an additional floor and restaurant. OSHA's inspection found that twelve inch cinderblocks were being hoisted from the ground and stacked on the fifth floor. Three employees were on the second floor working. The front 8 feet of the fifth floor then collapsed and continued down through all the floors to the basement. Up to 100 blocks fell with the collapse. NY Times reported that this was Tamco's first commercial job and that prosecutors contended that Mr. Tam and Mr. Ai knew the structure was insecure and had ignored warnings by experienced people at the site.
