In 2009-2010, Innova provided designs for structural support for several casino mockup ceiling sections in the Cosmopolitan Hotel and Casino. The representation of one of them may be seen in figures (A) and (D): a plan view with the layout of the chandeliers on the drawings for construction and a picture of the light fixtures as they are being installed on-site, respectively. The subcontractor's intention was to build two framing systems, one to hold the high density light fixtures and another one for the ceiling itself. After a brainstorming session with the subcontractor manager and superintendent, where different methods of construction were proposed, Innova put forward a one ceiling solution for both the light fixtures and the ceiling itself. This system is depicted on figure (B). Using a stick framing system of small steel tubes in one direction only, a very strong mesh was built with enough capacity to hold the overlay of ring chandeliers distributed at precise locations on the ceiling. Specific standard details had to be created due to the presence of HVAC ducts and diffusers in the way of the framing and to allow the field crews the flexibility to adapt the concept to the field conditions along the casino ceiling. These ring chandeliers were supported by unistruts laid in perpendicular direction and on top of the structural tubes while the ceiling itself is supported by hat channels of light-gauge material running also perpendicular but below the tube system. See fig. (C) Innova also devised a system to install the light fixtures in the field at the exact locations specified by the architectural plans. The steps to follow were:
- The coordinates of the center of each of the ring chandeliers were established as shown on the architectural drawings from a reference point.
- A shop drawing with those coordinates was created.
- Using the shop drawing, the coordinates were marked on the floor and unistrut channels with threaded rods were positioned over the grid overhead.
- The ceiling tiles were laid with holes that allowed the threaded rods to go through.
- The light fixtures were transported to the field and hung on the final locations per the architectural drawings.
It was reported that this system saved the subcontractor and the owner $300,000 in materials and labor fees.
