One-Day Facade Inspection of historical landmark building
How to Inspect All Four Sides of a Historical Landmark Building with Just Two Lift Moves
What was the challenge?
A national structural engineering and consulting firm was hired to inspect the historical John Wanamaker building, an abandoned railroad station turned by the retail pioneer into one of the first department stores in the United States in 1861. The 12-story, 223-foot-tall Wanamaker building with almost 1,600 feet of street frontage is located in downtown Philadelphia across from City Hall.
Inspection of this building was challenging because areas on all four sides of the building could not be accessed with the inspector’s 150-foot JLG lift. And renting a taller lift would force the city to close four streets, disrupting downtown traffic. Also, the cost of closing four roads would run up to $10,000 per day.
Another option was to use hanging baskets or ropes. But given the building’s protruding roof fascia, dropping swings or rappelling would not get adequately close enough to the walls. Plus, this option would cost over $60,000 and would take several days to set up and take down. In addition, S. Juniper Street’s narrow 18-foot passageway required a low-risk access method that would not endanger the precariously close walls.

What was the outcome?
With permits in place and a 10-minute setup, Alpha's IPAF-certified operator lifted the building inspector and reached all areas of interest on all four sides of the building from just three parking spots. In addition to being the safest, quickest, most convenient, and most comfortable façade inspection option, Alpha Platforms' contactless height access was also the cheapest, eliminating the cost of hanging swings, ropes, and insurance.
The engineering team discovered a new safer, more convenient, and cost-effective height access method to perform façade inspections.

We wanted to give it a try and see what this boom truck could do. We loved the idea of a wide basket that could reach up to 30 feet and get to the brick wall over the roof. The main reason we loved the truck was how it maneuvered the boom to lower the bricks inside a dumpster, which was located behind the truck. It saved us at least one extra day of work. It all went great.
The project was performed successfully, and we were really glad to have contactless means of reaching the building, as we all know that pipe scaffold might damage the structure, in this case, very very sensitive.
Alpha has the most efficient and leanest site setup time I’ve ever seen. My brother, who is the top climber of our group, first struggled to understand how this cage could go around the tower better than the crane - and when it did the whole 360°, he became a believer. Also, each laborer said how incredibly safe they felt - very different from the small crane basket. We were able to secure and push back the panels in place without the basket ever moving.
