With the steel frame for the first and second floors installed, crews are now spreading out steel deck or just “decking” that will form the floors for each level. This decking was lifted into place as a stack as each section of the two levels were completed.
In this image you can also make out a worker securing steel rope cross ties between the upright steel frames. These cables are needed during the construction process to provide lateral support until the entire frame is secured to the exterior walls on the basement level. After the foundation is secure the ties will be removed.
