New Royal Adelaide Hospital

The engineers for the NRAH wanted an easy to install ceiling system that would meet stringent seismic and health requirements plus provide extensive accessibility as is the case with grid and tile systems. By eliminating the typical extent of bracing required for other systems hence maximising the ceiling void space for the multitude of services found in hospital ceilings. Furthermore, providing characteristics that meet the stringent health requirements of this landmark facility, the Kwikloc Seismic Ceiling System provided the ultimate solutions. The system's unique ability offers both Seismic movement and resists loads at the highest benchmarks as well as offer high hygiene function through the maintenance of a flat even plane ensuring accurate and precise grid to tile interfacing.

Seismic Requirements

The Kwikloc aluminium Seismic ceiling grid systems have the structural capacity to meet and exceed the loading requirements of both AS1170.4 and NZS 4203 with respect to the horizontal and vertical earthquake forces. Specific design requirement standards for the Kwikloc System are available for the various areas and activity levels throughout Australia and New Zealand. 

Performance Levels

The Kwikloc Seismic ceiling system brings to the industry new levels of seismic ceiling performance, having sustained up to 3G tested forces with 100% vertical uplift. This represents 25-30% increased performance when compared to other ceiling systems available on the market today. A representative of the testing facility in New York State, USA commented, “this system was tested to the limits of our equipment.” The Engineering Reporter/Photographer also commented, “this is a very good system. Best we’ve seen. Normally systems fail at 2.0 to 2.25” (note that standard testing requirements include 67% vertical uplift).


The system has unique advantages in ultimate seismic ceiling design. The wall bracket system facilitates fixing one side and floating on the opposite side of both plane directions in a ceiling installation, as required by Engineers. The use of a patented two-part wall angle system and sliding bracket assembly, provides the unique feature of maintaining a flat, even plane for accurate tile nesting throughout the entire installation. This is particularly important in health projects, e.g. hospitals, medic centres and laboratories, where hygiene standards are of high importance. 

Kwikloc has been used on many other seismic focused projects since the success of the NRAH and has proven to save thousands in labour costs due to the minimal bracing requirements in comparison to other systems on the market.
