The new Grand Teton National Park Discovery and Visitor’s Center is located along the Snake River, snuggled up against the Teton range at Moose Junction, a few miles outside Jackson, WY. The building construction utilizes materials consistent with the landscape and climate, with multiple log frames supporting a glulam rafter roof system making up the primary gravity load system. A vast sloping window wall system looks out to the Teton range beyond and is supported by custom steel mullions. The lateral system is a combination of concealed braced frames, moment frames, and wood shearwalls. This structure posed special challenges with roof snow loads approaching 300psf combined with the high seismicity of the area. The Visitor’s Center will be open to the public year around with the grand opening and dedication completed August 11, 2007. It is expected to draw over half a million visitors a year.

The University of Montana Grizzly football program has enjoyed over a decade of top ranked status in college D-IAA. With this success has come overwhelming demand for football tickets to home games. In 2003 BCE designed a 4,000 seat addition to the north end of the stadium to bring the number of seats to around 24,000. This was not enough though. In 2007 BCE was brought on board once again to add 2,000 more seats to the east side of the stadium. As the stadium grows, the problem and logistics of adding these seats becomes more difficult. The east side addition will perch over existing enclosed boxed seating with the structural steel frame cantilevering over 24 feet above the existing facilities. The new addition will also include a 4,000 square foot club room facility at the top for exclusive game viewing entertainment for the select ticket holders. The structural steel frame includes main frames that serve as both gravity and lateral load transfer mechanisms. The frames are put together to economically support the cantilevered section while limiting deflections to acceptable values.
The Missoula Harley Davidson is one of the most distinctive Harley Davidson stores in the western United States. The building roof structure combines long span glu-lam/steel trusses, steel bar joist and SIP panels. Walls combined wood with masonry. The lateral force resisting system was accomplished with steel braced frames. A large basement accommodates the extensive bike inventory and also winter bike storage space for the many area HD customers.
Location: Kalispell, MT Client: CTA Construction Budget: $1.9 Million Date Completed: June 2007
The North Kalispell Branch of First Interstate Bank is a new
construction building of 5700 square feet with a steel bar joist roof
system supported by steel posts and beams. The lateral system is
comprised solely of steel braced frames.
BCE has been the structural engineer for the majority of additions to CMC for over 17 years. Along with several additions to the hospital, we have also designed the structure for three large Physician Center buildings and a surgery center. Each building and additions had structural challenges involved in medical offices, laboratories, sensitive surgery areas, etc. We continue to be involved in projects at CMC and look forward to a long future.
BCE has provided structural engineering for several large retail and wholesale buildings throughout western Montana. These building types dictate large open spaces for maximum flexibility. Structural efficiency is key. A common theme for box store structures is open storefronts. BCE utilizes up-to-date design aides to efficiently accommodate the open areas with selective moment frames and braced frames.
Location: Whitefish, MT
Client: Nick Fullerton Architects Construction Budget: $2.5 — $3 million Square Footage: 12,500 s.f. Completion Date: Spring 2007 Structural Frame: Structural Steel, Brace Frames, Wood Shear Walls, Concrete Retaining Walls, Composite Concrete and Steel Upper Floor Construction
This addition to the existing wood-constructed recreational facility at Big Mountain Ski Area required large open span steel construction and wood truss construction. A combination of wood shear walls and structural steel brace frame systems were utilized to maximize the lodge atmosphere. Spread footings, pad footings, and grade beams were utilized for the foundation system.
Location: Bozeman, MT
Client: Comma Q Architecture Estimated Construction Budget: $900,000 Square Footage: 7,000 s.f. Completion Date: July 2008 Structural System: Existing Brick Walls and Timber Frame Roof
The renovation of this single story former warehouse building brings new commercial space to the revitalized industrial area of Bozeman. The existing construction of un-reinforced brick walls and heavy timber post and beam roof required a seismic upgrade with a new steel braced frame. Structural Insulated Panels applied over the existing roof provides insulation while preserving the historic structure within the space. A new addition will be constructed on the south side of the building, and existing pre-fabricated metal frames from a former attached building will be re-used as an exterior canopy.
A three story, 400 stall parking garage in downtown Missoula. The building consists of post-tensioned concrete slabs spanning over pre-cast concrete girders and pre-cast columns. Project included extension pre-cast concrete fascia panels on three sides for three levels.
BCE provided complete structural design for this open retail space building with opportunities for large, 30,000 sq. ft. spaces and also multiple smaller 6,000 sq. ft. to 8,000 sq. ft. spaces. Building incorporates steel stud bearing wall construction with steel joist and metal decking. Lateral, earthquake and wind forces are resisted by combination steel moment frames, braced frames and also sheathed shearwalls.
The 168,000 square foot facility, owned by Deaconess Hospital in Bozeman, MT is comprised of 4 different
structures ranging in 1 to 3 stories in elevation with underground parking facilities. The structural framework is comprised of steel and exposed heavy glu-lam beams, with the exterior walls framed with conventional dimensional studs and headers. The underground parking floors are comprised of concrete hollow core planks bearing on precast, prestressed concrete t-beams. The design requirements include seismic zone 3 and a 43-psf snow load.
At ten stories, the Millennium Building is one of the tallest landmarks in Missoula. The structural design portion of the building was fast tracked to facilitate foundation installation and structural steel procurement.The building structural components consist of a deep foundation system to accommodate seismic resistance. The main structural elements are moment resisting concentrically braced steel frames with concrete floors and metal decking.
BCE provided complete structural design for this large open retail hardware store. Building incorporated tall exterior steel bearing stud walls in conjunction with interior steel beams and columns. Roof structure consists of steel joists and metal decking. Lateral, earthquake and wind forces were resisted using steel bracing on the stud walls.
Helena Nissan Dealership
Location: Helena, MT Client: Mosaic Architecture, P.C. Date Complete: 2008
The newest auto dealership in Helena has over 22,000 square feet of display, office, and service space. The structural steel braced frame and steel joist framing allows for large open spaces for both display and service needs. The exterior walls are infilled with light gage steel framing with aluminum composite cladding attached to a portion. Concrete foundation walls and spread footings are the foundation system.
