Design Flaw???

Cement panels are the only possible units that would work for the purpose that they are there. Why, because if a fire were to start underneath the panels if they were fiberglass or plastic the smoke would kill everyone or the melting plastic dropping on people as they run from a tunnel fire would cause catastrophic injuries also.

Epoxied bolts, right..........

1 - fiberglass = flammable and needs maintenence

2 - good question and one they will be regretting for a long long time, I guess the eggheads that came up with it have used the method before don't know
sounds idiotic to epoxy screws in place, I mean moronicoke:

3 - maybe there was no room above for that, who knows, you'd have to see the drawings and plans.


I thought the epoxied screws were in question Larry. I heard they were too short. Also I can't imagine an epoxy being strong enough to hold up that kind of weight. That whole project is flawed with all the cost cutting shortcuts taken because of the overpriced coruption. Too many problems they just passed over to deal with later, that's not right. Whoever hired incompetent contractors should be held responsible also. There seems to be plenty of blame to go around and now the finger pointing begins.

I like epoxy actually, it has it's purposes.
I just used it to glue in some threaded anchors today to a solid surface countertop to hold in an undermount sink, it will also be siliconed together and if it is filled with water and fails, I would be very surprised.
I also used epoxy to hold my entire boat together and it pulls the kids on a tube at 20 MPH just fine.

I heard some of those bolts did NOT even have any epoxy on them quality control was lacking to say the least

epoxy = stronger than concrete.

atleast west systems is.

in the west newsletter a couple years ago they did tests in putting bolts into reinforced concrete using west....
the holes were oversized and either smooth or rough.

poured concrete into the holes.... bolt rips out easy
epoxy into smooth hole... bolt and epoxy plug rips out
epoxy into rough hole.... bolt epoxy and a fairly large chunk of the surrounding concrete rips out.

I have been out of construction supply for a few years but I believe most sprayed fireproofing is a mix of fiberglass and ?
And part of the big dig was the construction of 7 massive vent buildings just for the tunnels. I delivered to #5,6 & 7.
2 in Southie and one at the airport.

My problem is 14+ BILLION dollars and the ceiling is held up with superglue? For lack of a better description.
