Cantilever Scaffold on 28 Floor, Philadelphia, PA
If you recall, Superior Scaffold was called in to help crews get to the decorative steel structure on the outside of the top of this new building construction at 3601 Market Street.
But how could we get them and their equipment out far enough to work safely on this structure at the top of the building?
A cantilever scaffold from the floor below. For those of you not familiar with a cantilever system it’s basically a way to use leverage to extend out so the weight of the new deck is supported by the floor below.
The initial thought was a traditional cantilever system using aluminum beams, stringers and joists like we’ve done many times before… but smarter heads prevailed and proposed this system scaffold cantilever. It’s lighter, easier to set up, and more efficient. Crews needed to get to the outside of this super structure to skin it and finish it. You can see in the wide shot the shiny metal structure at the top of this building. We’ve essentially created a new floor around the exterior of the top of this building that will allow crews to get up to the next level.
The pictures are a kind of chronological progression from nothing to starting to skin the exterior of the steel structure.
Sit back and enjoy the view. It’s a pretty radical job that’s proving to be a win, win for all of the trades involved.
This is what estimator Pat McAndrew saw that allowed him to make the determination that we needed a cantilever scaffold for access.
And this was the floor beneath the decorative steel structure that would house the cantilever scaffold.
Here is it with Rich and crew starting the assembly process.
Some great shots of Rich getting this scaffolding built and in place. I will have video to add to this blog in a few days.
You can see that crews had to build multiple levels for this cantilever.
This gives you a view of how the scaffolding allowed crews to reach the top of the steel structure.
This photo really shows the top of the structure and how far around the cantilever went.
And from the ground you can really see just how large it was. This was a U shaped design with a 220 foot long run on the 36th street side by a 40’ run or return on the Market Street side and then a 12’ run on the Filbert Street side. Each one of the decking planks also has to be tied down so it won’t shift or lift in the wind.
This picture shows the work progressing down the steel structure.
Here you can see the detail that went into erecting the cantilever.
This gives you a good perspective on how the cantilever worked with the decking on top.
It provides a super stable, safe, work platform for all the trades up there.
Crews are starting to skin the exterior of the structure.
And finally, here you can see crews getting to the underside of the steel structure.
I will add more pics once it’s completed and I will keep you up to date as this job progresses.

This 28-story mixed-use development will consist of ground floor retail space, five levels of parking to accommodate 201 cars, and 23 floors of residences. The 363 residential units will be a combination of studio/efficiency and one- and two-bedroom apartments. A rooftop amenity level with an outdoor pool deck is also planned.
