Double Wide, frame vs. system scaffold – when to use
At first glance, what do you see? A double-wide canopy spanning the entire sidewalk?
If you did – you would be correct but there is more to it than meets the eye. You don’t think we would just toss up a double wide sidewalk shed using our famous 767-00 “Philly” frames would you? Of course not. What you have to remember is that this a large span we have to cover so the facade resoration can go on overhead. And there are certain regulations that are mandated by our state as to the amount of weight this canonpy must support. In Philadelphia it’s 300lb psf.
My first thought was; why didn’t they use a system scaffold to bridge the gap? I understand that there would have to be two foot towers to support the beams and that would be a bit of cluster (you know what). But I’m no engineer. So then I thought, why don’t I just ask Superior Scaffold top engineer, Mike Leone? After all, he’s the man who has to design all these scaffold projects to meet code. I’ll let him tell you in his own inimitable way.
“You can make system scaffold work in a situation like this, but you would have to configure it properly and have enough posts/verticals and watch your leg spacing to get 300 psf rating. It would be a lot more pieces than using the canopy frames and would take longer to erect. So this is faster and less expensive and you get the same rating,” said Mike. “The City of Philadelphia’s Department of Streets Code requires a minimum interior opening of 6 feet. The Philly frame, as the name implies, was made specifically to comply with these codes.”
So there you have it. Not only is up to code but can also be faster to erect. I noticed another feature of this type of set up as well. It could help with the pedestrian traffic flow. It creates an isle-like walkway where traffic can flow easily in both directions just like on a highway.
And I just love to see the photos of how they erect these projects. Take a look.
They also painted the wood panels to help match the decor of the building. That’s another little added touch that Superior offers. Very cool.

That reminds me… Cue the music. “Spanning the globe to bring you the constant variety of scaffold… the thrill of erection… and the agony of having to take it down… This is Philly’s Wide World of Scaffold! Sorry, it just brought me back there for a minute.
