Building and Bridge Design That's Solid and Safe

WSN's structural engineers are qualified as Minnesota Department of Transportation Bridge Consultants.

We are also prequalified Consulting Engineers by the North Dakota Department of Transportation.

Our structural team provides county engineers with recommendations for condition code revisions, structural rating revisions, load postings, and bridge replacement versus rehabilitation. 

  • Vehicular Bridge Design

    Widseth Smith Nolting's structural engineers have designed hundreds of bridges across Minnesota and North Dakota. Our award-winning designs ensure safe, efficient travel that can stand up to harsh weather conditions and heavy traffic volumes. 

  • Pedestrian & Trail Bridge Design

    Our team of structural engineers have designed numerous pedestrian and trail bridges, including multiple projects along the Paul Bunyan State Trail, that provide a safe recreational experience for all users.

  • Building Structure Design

    Our engineers make sure your building is solid. We also make sure the structure ties into the design of the building established by the architects and interior designers. 

Good People who deliver Great Design.

That's what you can expect working with our structural engineers. We'll treat you right and we won't settle for anything less than excellence.

Structural Engineering Services for Bridges

WSN's structural engineers have designed more than 270 bridges for 75% of Minnesota's counties.

  • Preliminary & Final Bridge Design

    Based on the field Topo Survey and Hydraulic Analysis WSN's structural engineers will design a new bridge that meets the hydraulic requirements and fits the project site. Bridge width will depend on traffic requirements and the client’s needs. Bridge type will depend on economics and what best fits the project site. Structural bridge design will be based on latest AASHTO and MnDOT requirements.

  • Approach Design

    Our structural engineers can provide construction plans for the approach work to tie the new bridge into the existing roadway surface. Plans will include erosion control, SWPPP, and a detour layout to keep your traffic moving.

  • Bridge Rehabilitation

    WSN's structural engineers have completed many projects that rehabilitate existing bridges to extend their service life for many years. We also complete bridge repair projects if a single element is reducing the use of the bridge. Feasibility reports are typically completed to determine if repairs, rehabs, or replacement structures are the most appropriate course of action.

Structural Engineering Services for Buildings

Our team of structural engineers will make sure the structure in your building is designed to meet all standards and regulations.

We'll collaborate with the architect to make sure design intent is carried through into exposed structures.

  • Building Structure Design

    Our structural engineers will design an economical structure that fits the vision of the architect and the client. Structure types include steel, reinforced concrete, precast, masonry, and wood.

  • Construction Observation

    WSN's structural engineers review contractor shop drawings for accuracy and completeness and provide periodic observations of construction to verify document specs are met.

  • Existing Building Analysis

    WSN's structural engineers can analyze your existing building structure to determine structural capacity, load ratings, and feasibility for remodeling or repairing.
