Doors Around Boston

On a weekend trip to Family Science Day, I saw these super-tall doors at the convention center:

Can you spot the code issue with the convention center’s entrance doors below?

Boston’s Faneuil Hall was built in 1742 as a meeting hall, and is now part of one of the most visited tourist sites in America.  I know these doors aren’t original since the building was destroyed by fire (except its brick walls) in 1761 and has been renovated several times.  But they’re quite old and an interesting design – one narrow swinging door and a set of bifold panels.

I’ve visited Quincy Market many times, but I never noticed that when the glass and aluminum entrance vestibules were added, the existing doors were left in the open position.  The existing doors (and hinge below) are visible through the glass on the side of the vestibule.

A couple of interesting door pulls on the South Market Building:

And I noticed this “extended lip” for an electric strike:

    Cross Bar exit devices are a no-go on balanced doors.

    Did you push on the tall doors at the conv ctr?? If so did they move easy??

    I wonder why in the second picture the doors swing that direction?

    Balanced door bar should only extend 1/2 the width from the latch side

  3. Chuck Park says:

    The entrance doors are balance doors, and can not be opened if you are pushing on the pushbar from the center towards the hinge side.

    Entrance Doors:
    These are Balanced doors, per NFPA 101, panic hardware on balance doors should be push pad type, not cross bar, and the pad should not extend more than approximately half the door width.
    These cross bars extend full width.

    I also seem to recall something about glass being directly behind a cross bar or push pad, but cannot find a reference to it anymore. Maybe I imagined that one.

    Push plate position on tall doors looks too high, unless you took photo on your knees.

  6. Eyal Bedrik says:

    The panic hardware shall be of the push-pad type

  7. Clair E Gunnet Jr AHC says:

    The only code issue I can see at the moment is the balanced door pivot may be considered to intrude on the 10 inch bottom rail for ADA. After 24 hours this is the best I can do!

      No worries – it’s kind of an obscure code requirement. Balanced doors are required to have touchpad-style panics (not crossbar), and the actuating portion can’t extend past the half-way point on the door (approximately). With the crossbar devices, if you push on the wrong end, a balanced door won’t open.
