GSA Region 8, Montana Federal Courthouse
GBG conducted a traffic study regarding the vertical transportation needs of this new federal courthouse. It was determined that five traction elevators would be required to serve the building, including two passenger-only, one dual purpose passenger/freight, one for judges only, and one for prisoner transport. At the conclusion of the study we provided a performance specification for use by the design/build contractor.
WSDOT 519 Intermodal
As part of the firmâ€™s On-Call Mechanical Engineering Contract, GBG provided elevator design and mechanical engineering services for design-build specification for an elevated walkway near Safeco Field. Performance specification for a 2-stop roped hydraulic elevator with a glass hoistway and as much glass in the car as code would allow, for user security. GBG worked closely with WSDOT Engineers on the bid solicitation and during construction administration. In addition to the elevator performance specification, we provided a mechanical performance specification for the machine room cooling system.
O'Brien Building Renovation
The Oâ€™Brien Building, located on the State of Washingtonâ€™s Capitol Campus, is the home of the Stateâ€™s House of Representatives. Built in 1940, the 4-story building became an earthquake and fire risk after the Nisqually earthquake in 2001. GBG assessed and completed the design for two elevators. The scope included protecting and re-using the historic bronze, exterior elevator doors.
WWU College Hall Elevator
GBG provided the design for the addition of a machine room-less traction elevator to this existing historic building on the Western Washington University (WWU) Campus. This project provided GBG with a unique challenge - the existing buildingâ€™s exterior could not be modified visually except as specifically approved by the WWU Architectural Committee. The challenge extended to the attic space, which didnâ€™t have enough room to allow a conventional elevator to fit without modifying the roof. GBG was able to resolve this issue by using a Kone Ecospace elevator, which requires less space above the top floor for overrun clearance and eliminates the need for a conventional machine room.
University of Washington HUB Renovation
GBG provided elevator and acoustical services for the renovation of the Husky Union Building (HUB). The project includes work on six of the seven geared-traction elevators, four replacements and two modernizations. The elevators include three passenger only, one freight only, and two dual-purpose, with each serving between 3- and 6-stops.
Greenbusch also provides technical expertise in acoustical engineering, audio/video consulting, mechanical engineering and commissioning services.
