432 Park Avenue Residential Tower – Scaffolding System

Construction of 432 Park Avenue residential tower in New York City


Provide access to highest residential tower in the western hemisphere during all phases of construction


Efficiently and safely transport 600 workers, equipment and materials up and down the tower


To engineer a hoist solution, which would use the least amount of wall space possible and at the same time address the concerns regarding extreme height and workers’ safety, SafwayAtlantic, a BrandSafway Company, started to work with Lend Lease, the contractor hired to build 432 Park Avenue two years before the project started.

With a common tower, six different hoists, and two windows for access to minimize obstruction, the access solution for the project was designed to allow the building to be closed in earlier than a more conventional configuration of the hoists. A common tower is typically made from a four-pole configuration of shoring and scaffolding components decked at each entry level to allow exit of the hoists and access to the building under construction. A temporary structure built alongside the permanent facility, the common tower has wind load, floor capacity requirements and a fast-tracked erection timeline much like the property under construction.

The tower solution, engineered by SafwayAtlantic, abandoned the conventional four-pole components generally used for the common tower in lieu of actual rack and pinion tower sections at the four corners. This offered a means for adapting mechanical access equipment to perform the construction of the platform in a safer and more efficient way.

In addition to the six personnel and material hoists in operation on site, the comprehensive access solution SafwayAtlantic provided included scaffolding, sidewalk shields and roof protection for the adjacent properties.
