Outer walls being sheathed

Progress continues on the addition to Margaret Chase Smith School.  Masons are hard at work building the stairwells to the second floor.  The welders have been busy welding panels onto the roof of the whole addition.  Electricians and plumbers are on site readying the addition for their portion of the project.  The pictures attached show that the outer walls that were framed are now being sheathed.  It will not be long before the addition may be enclosed and the building of the individual rooms may start.
