Government Center Station Glass Fogs Up, Needs To Be Replaced
The news that the Somerville Green Line extension is facing a possible $1 billion cost overrun wasn't the only downer at Monday's meeting of the MBTA Fiscal and Management Control Board.
Some or all of the glass for the new Government Center headhouse in Boston is defective and needs to be replaced, the MBTA's General Manager said Monday.
"Fairly soon people will start to see the glass that's been up for several months now removed, and the area covered with tarps to protect the interior from the weather as the glass is sent back to California to be remanufactured and reshipped out and reinstalled," said MBTA General Manager Frank DePaola.
During his comments to the MBTA Fiscal and Management Control Board, DePaola said there is an issue of workmanship in the glass and glazing of the structure now rising out of Government Center Plaza. According to DePaola, seals between panes of glass have failed, allowing moisture to get between them and causing fogginess to appear inside the windows.
DePaola said the project's contractor, Barletta Heavy Division, is fully responsible for workmanship issues and should cover the cost of replacing the panes, which will be done in batches.
"Those double pane windows, those seals have failed," DePaola said. "The inner gas has leaked out and moisture has gotten in, so if you look at many of them closely you'll see fogging on the inside of the window."
All defective glass will have to be replaced, MassDOT spokesman Mike Verseckes told WGBH News after DePaola's remarks, but it's unclear how many of the panels will need to come down. The replacement of the panes will not affect the expected Spring 2016 opening of the station, as Barletta will do the replacement work concurrently with the station's construction, DePaola said.
