New York City Transit has stepped up efforts to re-build Line’s 1 and 9 of the city’s damaged subway by pre-qualifying five contractors for construction work. The five, selected for their experience in such work, are Slattery Skanska, Schiavone Construction Co, Halmar/Granite JV, Tully Construction Co and A.G. Pegno. The approximate US$200M work could begin as early as next month.
