One of these business suites is the Chairman's Suite, located on the top three occupied floors- 152-154 of the building. In partnership with TopAkustik, RPG provided all of the ceilings for this Suite in a complex non-rectangular pattern, finished in a high gloss white coating making it the highest acoustical product system in the world! RPG worked with Skidmore Owings Merril (SOM), Chicago office, PMK Dallas and Dubai and our local representative to oversee the entire project, with drawing supervision, field measurement supervision and interfacing with TopAkustik. The ceilings perimeter was extremely complex and followed the irregular boundary of the room with an offset, which was painstakingly determined from extensive field surveying.

The photos illustrate the seemingly triangular panels in the ceiling. However, the panels are actually created in semi-rhombus shapes with a faux reveal to create the triangular look. The entire layout is without a single straight line and each panel edge is defined by another slight radius. The panel lines emanated across the building in a sweeping fashion to create over 750 unique panels over the 3 levels and 2500 panels produced in total. To add to the complexity of the project, the lighting and other trade penetrations were factory cut in the panels for the precision of cutting. The panels were produced with 2 mm perforations that were drilled with an offset of 50 mm from each panel edge. The panels followed the perimeter line of the building with multiple details to consider for ceiling to wall transitions. The factory provided custom curved trim in multiple heights to achieve the design aesthetic for each transition point.

The panels were suspended on a custom engineered grid that allowed partial accessibility. Topakustik took their standard Z-grid and supplemented the hardware to allow for such a unique ceiling layout. It required custom pieces to allow main runners to follow the basic layout of the ceiling while having panels that could intersect the main runners and a myriad of angles. The result is a complex ceiling with demanding panel joints that also provides 50% accessibility throughout the 3 floors. All in all, this was an incredibly complex project that required precision and craftsmanship that only Topakustik could provide. The completed and installed panels offered the desired acoustical absorption and aesthetic appearance that was so important to the designer and tenant.

This project along with The TimesCenter, New York, NY and Morgan State University, Baltimore, MD demonstrates RPG's pre-eminent role as a leader in providing complex engineered absorptive wood wall and ceiling systems. We offer a wide variety of panel, veneer, finish and suspension options to

address almost any requirement.
