The lighting system installed is Electronic Theatre Controls, Mosaic Control System. The fixtures are ReachElite by Color Kinetics. Each light fixture is individually programmed into the Mosaic system with a unique address and then controlled wirelessly through a digital pathway or DMX device. Each building has an antenna which had to be precisely aimed at the City Hall receiver where the head end equipment is located. Once the transmitters and receivers were communicating, each of the 225+ light fixtures had to be aimed at a detailed location on City Hall. This aiming was performed at night and took several weeks to complete.

The lighting was installed on 10 different facilities surrounding City Hall, including the Wanamaker Building, the Ritz-Carlton, Centre Square, and 1515 Market Street.

Schedule development, material procurement and steel fabrication were the first considerations. Each of the ten buildings and City Hall had to be surveyed, elevators measured for steel beam sizes and the weights accounted for. Access times were documented, building Engineers were briefed and Safety considerations began to take shape. Some of the buildings had existing steel frames that required modifications and anchor testing, while other installations were completely new. This process, including follow-up visits, verifications and submittal approvals took several weeks to complete.

The new structural steel is USA certified, and was fabricated and installed by a Local 401 Ironworkers affiliated subcontractor, EH Ironworks.

Safety was of the utmost importance for this project – and every project.  Each light weighs 75 pounds and needed to be hoisted up onto scaffolding systems before being set on a tenon bracket that were located dangerously close to the edge of the building and in some occasions, over the edge and 30 plus stories above grade.  Together, we were able to develop plans that kept not only C&D Personnel safe, but the building tenants and public as well.

C&D project management and field personnel worked closely with building facility managers and Principals. Through solid coordination, planning and communication, C&D was able to limit daily disruptions and provide a quality installation.
