Franklin Institute and the Emergency Egress

Sounds like something from the minds of Jerry Bruckheimer and Michael Bay

The Franklin Institute is a museum in Philadelphia, Pennsylvania, and one of the oldest centers of science education and development in the United States, dating to 1824. The Institute also houses the Benjamin Franklin National Memorial.  They are currently hosting the Titanic Artifact Exhibition – and they are putting a new addition onto the side of the building.  This is where Superior Scaffold comes in.

The needed an emergency egress – to put it simply, an emergency exit stairwell from the second floor down to the ground.  Sounds simple, right?  Of course not.  Why?  Because the ground beneath the proposed emergency stairwell is being excavated.  Something about spy tunnels from the old Manhattan project that run from the basement of the Franklin Institute across the street into the basement of another building.  Now, this is just conjecture offered up from some unnamed sources on the job.  But just think about it.  How cool would that be?

Since I can neither confirm nor deny these allegations we can only assume that Oppenheimer and his crew were shuttling top secret plans back and forth while developing the world’s most destructive weapons.  Or it just could be that something beneath the ground needs to be removed or updated for structural reasons.  Stairs, water pipes, electrical, who knows?  You make the call???  Maybe Jerry Bruckheimer should make a movie.  Superior Scaffold stars in:   Ha.

Either way, the egress could not be built straight from the second floor down to the ground.  This is where the creative chaps at Superior Scaffold come in and design a scaffold that spans the 36’ area that’s being excavated and then takes you down to ground level.  Since they had to span the gap – they designed a free standing 4′ X 5′ X14′ high unit that sits 40’ away from the exit of the building.

You can see where Superior engineer Bob Robinson called for a thru-bolted channel on the side of the building to carry the giant 40’ steel beams.  Then on top of those beams they constructed a 5’ wide walkway that takes people out and over the excavation below.

So when you look out of the second floor about to exit you will see a walkway that spans the excavation below, completely covered and hand railed.   On the other side of the deck are the stairs that take you down.  Problem solved.

And since it was free standing, the guys put a roof on it, added hand rails and debris netting around the sides to knock down the elements.  It’s quite a lovely emergency egress.

You see, it’s the simple things in life that make people happy.  Superior is the best at coming up with functional solutions that make clients happy.

Shoring up the Ben Franklin Museum, Philadelphia, PA

The new Benjamin Franklin museum just off of 4th & Market in an area known as “Franklin Court” is under way.  This will be Philadelphia’s newest exhibit about Ben Franklin and when completed, the new Benjamin Franklin Museum will be underground!

Ben Franklin Museum – new concrete slabs and support steel.

Yes, an underground museum.  And that’s all well and good but it posed some real challenges when it came time to do the expansion.  You just can’t take a hundred and fifty year old building and slap a bunch of exhibits inside.  You need a complete redesign to support the architect’s vision.  And that exactly what they got.

If ever you wanted to see what shoring actually does – this is the time.  You can clearly see the work going on above the shoring and below the shoring.  It always amazes me at the sheer weight that these post shores can hold when you take in consideration the cement and steel necessary to make a job like this happen.

Beneath the concrete slabs you can see the shoring necessary to hold up the new steel and cement.

This was an extensive demolition of an old structure to open up the building.  Walls had to be removed, ceilings had to be shored up so new steel and concrete could be poured to support the new additions.

Another view from the basement.

15” thick Concrete slabs were poured and giant concrete beams were brought in to help support the weight.  That was probably the biggest challenge on the job.  The steel was so long it took several cranes and expert crews to get them in through the alley and into place.  Superior Scaffold shoring guru, Bob Robinson, had to calculate all of the weight loads so the proper equipment could be utilized and the work done safely and up to code.

What’s going on above the shoring.

Some of the concrete beams in the new design were 36” wide X 42” deep and spanned 42 feet  column-to-column!

When it’s all done, the exhibits will be divided up into different rooms that reflect various aspects of his personality and his life.  The museum will feature interactive displays exploring his life as a private citizen and statesman through individual, room-like installations. The library is intended to be the culminating experience.  Other 21st century additions to the underground museum include interactive elements like touch screen kiosks, a computerized version of Franklin’s glass armonica a musical instrument employing glass and water to create sound, and two-minute animated vignettes designed to help visitors understand critical turning points in Franklin’s life.
