How to erect a canopy – Aramark Tower, Philadelphia

It’s not every day that you get to see just how we erect a sidewalk shed (canopy).  We usually concentrate on the finished product and how well the client liked our work.  But today is another story.  You get to see just what it looks like before, during and after we install overhead protection on a job site.  We are going to look at the work done in the middle of one of Center City’s busiest intersections at 11th and Market – the Aramark Tower.

Crews usually start at night to avoid the massive traffic that will ensue during the daytime.  In this first shot they have started building the base framework which consists of the 2 inner and outer main posts (or tubes), the bracing frame (s), the jack (s) and the intermediate plate (s).

Here we see crews are just starting to put the steel beams on top of the aluminum posts.  These will be placed all the way down the run and act as support for the aluminum joists to follow.  Rolling towers are used to get crews up high enough to place the beams.

You can see here how the Superior Scaffold trucks deliver the equipment to the job.  Again, in the evening or early in the morning to avoid traffic.

This shot shows the main framework as well as the steel beams that will support most of the weight overhead.

Crews have carefully designed the layout so that doors and staircases are still accessible to pedestrians.

The aluminum joists are then laid over the steel beams for added support.   These will handle the weight of the planks and/or corrugated steel panels that will lay over top.

You can see how the pieces intertwine to create a super stable base for anything going up on top of it.

You can see how the height of the rolling tower is adjustible to reach diffrerent eleveations.

And then finally, in this case, the Microlam wood planks are added to the top of the sidewalk shed.  In downtown Philly, canopies have to have a 300 lb/sq foot rating so you can put suspended scaffolds on top or even additional scaffold, if needed.

And the last part of this very long process is adding the 4X8′ debris panels that can be painted to match the client’s decor (which these will be) or left a beautiful Superior Scaffold red.

As a finishing touch, temporary lights will also be strung beneath to illuminate the walkway at night.

And in a very simplified form, that’s how a canopy, sidewalk shed, overhead protection is assembled.  There are many different types of sidewalk bridges too – some made from scaffold frames, some from bridge columns and some from aluminum posts.  You can go here and see the different options we have available at Superior Scaffold.  Call (215) 743-2200 today if you need one of these beauties for your project.

Superior Scaffold – Firestone Library, Princeton University (Last Phase) Scaffolding the entire building

This is the last phase of the scaffolding and exterior renovations.

It’s also a follow up to our original post.  (scroll down for link)

Princeton University has committed to a comprehensive renovation of Firestone Library
and Superior Scaffold has been there every step of the way.  The entire building is scaffolded
and debris netting has been added.

Superior Scaffold was selected to help in the renovation of Princeton’s Prestigious Firestone library because of its long history working with historic buildings on the campus.

Superior Scaffold provided netting around the entire structure so that the Firestone Library could remain open during renovations

The renovation is a long-term project that is being done in multiple phases and will take almost 10 years to finish, during which time the library will remain open, and its collections available during normal hours of operation.

This the back of the library. You can see just how large the scope of this scaffolding job is.

Superior erected as system scaffold allowing crews to get access to all areas of this monumental restoration.

As stated above, the library has to remain open while crews do the work.

This is the right side of the Firestone Library – scaffold continues all the way around.

Superior also provided a series of debris netting and trash chutes to the project.

Directly above the main entrance. The masonry work is outstanding. Everything will look like new when crews are finished.

The Harvey S. Firestone Memorial Library opened in 1948 as the first large American university library constructed after World War II.  Roughly 1.5 million volumes were moved during the summer of 1948 from Pyne and Chancellor Green Halls, which until then had served as the University’s main library.  The library building was expanded in 1971 and again in 1988 and currently has more than 70 miles (110 km) of bookshelves, making Firestone one of the largest open-stack libraries in existence.  Though not the largest university library in the world, the library has more books per enrolled student than that of any other university in the United States.

Superior Scaffold Shoring up the Mid-Atlantic

Can you say needle beam?  I just love that word.  Needle beam, needle beam, needle beam.

Did one just appear?

It did.  (See the photos below.)

scaffold rental, scaffolding rental, shoring rental, PA, NJ, DE, MD

That is a needle beam.  I know, like me, you probably thought it would resemble an actual needle but no.  It’s just a term that the engineers like to throw around loosely anytime a beam needs to be put through something for support.

scaffold rental, scaffolding rental, shoring rental, PA, NJ, DE, MD

Here’s the actual definition of needle beam from the free dictionary:  in shoring, the horizontal cross timber which goes through the wall or a pier, and upon which the weight of the wall rests, when a building is shored up to allow of alterations in the lower part.

Well that makes sense.  So now look at the picture.  You see the needle beams?

A store in the Hillview Shopping Center in Cherry Hill, NJ wanted to expand the front entrance to their building so the call went out to Superior Scaffold, who are experts with all things shoring by the way (shameless plug).  So the grand wizard of engineering, Bob Robinson, devised this nifty bit of shoring using 20 kip heavy duty post shores to support the exterior walls with needle beams sticking through.

And on the inside, Superior used their hi-load shoring frames with aluminum joists to support the bar joists.

scaffold rental, scaffolding rental, shoring rental, PA, NJ, DE, MD

How about that?  I just realized that I’m going to have to do a post just dealing with scaffold terminology.  Kind of like the urban dictionary for scaffolding.  I’ll get to that so you all know what 20 Kip means, and what Bar Joists are, etc.

Anyway, the job went swimmingly and the client was thrilled.  And I am happy to report that there were no Beetlejuice sightings or random appearances of needle beams either.

Needle beam, needle beam, needle beam….

Poof.


Nothing’s easy – The Road from Israel to South St. Philly for the famous LOD Mosaic

On January 26th, Superior Scaffold was proud to help bring to the East Coast one of the most incredible Roman Mosaics ever unearthed.  The challenge to get them inside the University of Pennsylvania Museum of Archaeology and Anthropology was something of an engineering marvel taking scaffolding teams, crane operators, art curators, engineers, and scores of people.


Waiting at the door

But first…      A real-life “Cover up”.

In 1996, workmen constructing a new highway in Lod, Israel (near modern-day Tel Aviv), made a shocking discovery: a 1,700 year old Roman mosaic under the surface of the road. At that time, the Israel Antiquities Authority conducted a rescue excavation that revealed a full series of mosaic floors, measuring roughly 50 feet long by 27 feet wide. Conservators provided preliminary treatment of the mosaics, but they were then reburied until funding could be secured for the full scientific excavation and conservation. In 2009, excavators unearthed the Lod Mosaic once again. The mosaics were then separated into panels and rolled away from the earth.  Today, they remain in near perfect condition.  Three of these panels are on display in Unearthing a Masterpiece.

This piece is very unique because it lacks human figures.  It was likely commissioned by a high-standing Roman official for his private home. Alluding to gladiatorial games, the mosaic panels depict scenes of hunting, trading, and marine life.

And because these tiles date back to 300 CE and are some of the most complete, well-preserved, and largest Roman mosaics ever found, everyone involved wanted to keep them that way.  So the call went out to Superior Scaffold to help get them into the building.  Piece of cake, right?  Wrong.  Follow the photos below to see just what was involved.  Now, we were just one cog in a very important machine.  But our piece was of utmost importance.

These tiles were so large that they had to be placed into 7 gigantic wooden crates and shipped to Philadelphia.  And on the morning of January 26, 2013 two large box trucks arrived and blocked South Street in front of the Museum.

Crews position the first crate

The biggest challenge on this job, that required weeks of careful planning, was that these crates couldn’t just be waltzed through the loading dock and up to the third floor where they were going to be displayed.  They were way too big and heavy to fit.

Another crate coming over

They had to be hoisted by a 100 foot crane up off of South Street and deposited onto a giant 16’ tall platform that Superior built over the main stairs and Warden Garden Coy pond that straddled two giant sliding wooden doors accessing the grand staircase on the third floor into the Pepper Gallery.  Wow, that was a mouthful.  But seriously, look at the photos.  Superior’s platform allowed the giant crates to be maneuvered directly inside to the display area where curators could uncrate the masterpiece and put it together for display.

Sitting on top of the system scaffold, Superior used 9’ aluminum stringers crossed with solid plank and then topped with plywood.

Then entire unloading process took approximately 6 hours.  Of course, our part started long before the trucks arrived and lasted well after the crates were unpacked.

In the end, the Museum safely unloaded, unpacked, and assembled the Mosiac in time for their ribbon cutting ceremony on February 10, 2013 to start the exhibit (Unearthing a Masterpiece:  A Roman Mosiac from LOD, Israel) which runs for a limited time.

Estimator Pat McAndrew not only oversaw the installation but also attended the opening where he took these photos of the famous Mosaic.

Superior will be back out assembling the same scaffolding in May when the exhibit is packed up again and shipped to the Louvre in Paris.  After a short time there, it will make the trip to Israel and it’s final resting place in a specially built museum.  So see it while you can

And a shout out to Bob Thurlow in charge of Traveling Exhibits at Penn Museum for some of the great photos of the crates going in.
