7 line extension opening to be delayed a few monthsBy
While we all gathered to celebrate Mayor Bloomberg’s 7 line extension a few weeks ago, the rest of New York City is going to have to wait even longer as this project too has been delayed a few months. According to MTA documents to be presented to board members on Monday, due to issues with the escalators and elevators at 34th St. and the transmission backbone system, the opening of the station at Hudson Yards will be delayed until at least late summer/early fall of 2014 and possibly into the fourth quarter of 2014.
The three main concerns seem to focus around equipment. The hand rail motor for the high rise escalators at 34th Street failed the Factory Acceptance Test; the transmission backbone system which operates all major systems including HVAC, fire alarms and the elevators and escalators were delayed; and the inclined elevators at 34th St. have twice failed Factory Acceptance Tests. The MTA notes as well that “installation logistics and access…may become an issue.”
According to the documents, the MTA is working with contractors to mitigate the delay, but it’s not likely that the agency will meet the previously promised June 2014 date. The delay should not impact the cost, but it is yet another sign of problems managing major construction projects. By the time it opens, the 7 line extension will be nearly two years late past original estimates and one year off of its revised timeline that had service commencing in December.
