Bringing a 110 year-old building into compliance
The building engineers wanted the anchors to be installed below the roof deck instead of above it. Since the roof was fairly new they also wanted to minimize roof penetrations as much as possible. In order to meet these requests as well as create a safe solution, Rooftop Anchor designed special anchors that were designed to be installed into the wood joists beneath the roof. Because the anchors were installed below the deck they also had to be taller than a standard anchor, meaning that they had to be made stronger to compensate for the additional height. Rooftop Anchor's professional installation team put together a special block and tackle system to hoist the anchors up into their installation locations from on top of the roof deck. The anchors were then screwed into place from inside the building.
In order to give window washers closer access to the windows, rigging sleeves were used in conjunction with an outrigger beam, which allows them to run their equipment through the sleeve in the cornice of the building and therefore bring themselves close enough to the windows to effectively and safely wash them.
Despite the scope and complexity of the project, Rooftop Anchor's team was able to complete the entire installation of the safety system in 5 nights. Both the building owners and the contractors working on the roof are very satisfied with the result, and we are proud to have been able to work on such a unique project.
