Madison Street Pedestrian bridge

Client: Missoula Redevelopment Agency
Location: Missoula, MT
Team Consultants: WGM Group, OZ Architects, Maxim Technologies

BCE served as prime consultant on the project. The unique nature of the project required BCE to perform evaluation of the structural capacities of the existing bridge piers in addition to the unique layout of the new multi-span suspended bridge. BCE was in charge of producing and coordinating the design documents for approval of both City and State agencies.

WGM Group, Inc. (WGM Group) teamed with Beaudette Consulting Engineers, Inc. (BCE), Maxim Technologies and OZ Architects on the design and construction of a new bicycle-pedestrian bridge over the Clark Fork River in Missoula. This unique bicycle-pedestrian bridge passes through the abutments of the existing Madison Street Bridge. The new bridge allows pedestrians and bicyclists to safely and conveniently cross the river at trail level below the Madison Street Bridge. This innovative extension of Missoula’s Riverfront Trail system provides uninterrupted access from Orange Street to Madison Street on both sides of the river.

BCE provided structural design and served as the lead engineering firm on this $1.25 million Missoula Redevelopment Agency project. WGM Group provided project management, survey, NEPA documentation, hydraulic analysis, environmental permitting, and construction administration services. The bridge was completed in February 2006.

Cable Stayed Stacker Conveyor —
Roaster Projects, Carlin, NV

Client: Selway Corporation — Stevensville, MT

BCE provided the structural design for this 300’ long conveyor along with numerous other conventional conveyors. A tapered truss consisting of single angle web members and structural tee chords supports the stacker conveyor. The bracing for the main tower is configured with a moment framed opening to allow passage of the truss, large horizontal thrusts from belt pull and seismic forces are resisted at an A-Frame on the lower end. The "cable" stays are 8" dia. Pipes with strake plates. The response spectrum method was used for seismic design.

Travelers’ Rest Suspension Bridge

Client: Travelers’ Rest Preservation & Heritage Association — Lolo, MT

The Travelers' Rest Bridge is currently awaiting the go-ahead for final design. A preliminary analysis has shown that a traditional suspension bridge utilizing round, small diameter timber is feasible in this 140 ft. long structure. These members will be used in the towers, floor system, and stiffening trusses. Member connections developed in BCE’s involvement in the Small Diameter Timber Initiative will be used along with a mechanical grading system for round timbers. The USDA Forest Service, Forest Products Laboratory has initiated the study to develop the technical basis for this grading system. Along with development of the timber structure, refinement of bridge alignment will be done in final design.

Orange Street Work Bridge

Client: Bodell Construction Company — Missoula, MT

BCE provided design services for temporary structures on this project. This included sheetpile embankment retaining walls and cofferdams. The work bridge was designed to carry 100 ton truck cranes for everyday use and 375 ton crawler cranes for Drilled Shaft construction. The work bridge was required for year round use including bridge demolition and prestressed girder erection, this required careful analysis of outrigger loading and track pressure concentrations on the crawler cranes. Auxiliary piers were required for access to the drilled shafts and these piers were configured to resist significant additional loading from drilling and casing removal. BCE was responsible for the complete bridge design including the braced pile bents. This work bridge is currently being used in phase II construction and was used for the entire phase I construction period.
