The Department of Buildings is going after construction firms that are not following an anti-smoking law enacted in the wake of the Deutsche Bank building fire that killed two firefighters.

Investigators determined the August 2007 fire was started by a discarded cigarette.

This past summer, the building code was amended to prohibit smoking at any construction site.

DOB officials say its inspectors have issued nearly 250 summonses since September 1 for smoking at building sites, cigarette butts found on the sites, or failure to post "No Smoking" signs.

So far, more than $245,000 in fines have been levied.

Meanwhile the Manhattan district attorney's office is still deciding whether to file manslaughter charges against Mitch Alvo, a director at the John Galt Corporation.

Alvo was accused of ordering workers to remove the standpipe in the former Deutsche Bank building.
