Project Description:

The CEDE - Civil Engineering Department is requiring a proposal from the group of student engineers to provide comprehensive engineering efforts related replacement of the Willow Creek Bridge on State Highway 3 in Idaho.  The scope of the project will require the student team to provide documentation of current conditions as well as a complete design solution for the replacement structure. The Student Design Team is encouraged to consider and provide several alternatives in their proposal. The Team should recommend the best alternative for the replacement bridge based on initial cost, expected loading, constructability, environmental concerns, and future maintenance costs. The Design Team should evaluate the hydraulics of Willow Creek as it discharges to the Coeur d’Alene River using HEC-RAS to size the bridge openings and ensure that all FEMA floodplain regulations are met. 


A structural analysis (live, dead, wind, and earthquake loads) and design (deck and girder design) should be completed for the replacement structure to ensure that it can support the necessary loadings.  A foundation design for the replacement structure should also be completed considering the bridge loadings and the hydraulic scour analysis results (lateral earth pressure, applied forces, abutment and pier dimensions, bearing capacity, earthquake and wind load, transfer steel, etc.).  Finally, a transportation design of the SH-3 highway should also be completed (roadway alignment and profile, roadway cross-section, pavement design, stormwater design, and signage placement, etc.). 


Tasks to be addresses in the Proposal will include, but are not limited to the following:


1.         Hydrologic and Hydraulic Analysis:

Complete a HEC-HMS and HEC-RAS analysis that will comply with all FEMA and Idaho Transportation Department (ITD) regulations. This will require existing conditions models with calibration, proposed conditions models, bridge opening design, scour analysis and countermeasure design.


2.         Structural Analysis and Structural Design:

Complete analysis using live, dead, wind, and earthquake loads. Make alternative designs for deck and girder arrangements. A foundation design for the replacement structure should also be completed considering the bridge loadings and the hydraulic scour analysis results (lateral earth pressure, applied forces, abutment and pier dimensions, bearing capacity, earthquake and wind load, transfer steel, etc.).


3.         Transportation Design:

Roadway design of the SH-3 highway will also be completed (roadway alignment and profile, roadway cross-section, pavement design, stormwater design, and signage placement, etc.



The project will also require the implementation of project management techniques in the completion of the engineering efforts, including interaction with HDR Engineering as the project sponsor, liaisons, project advisors, monitoring work efforts and progress, updating the project schedule, preparing status reports, gathering information required for design in and from appropriate regulatory agencies.


Students will be responsible to make required presentations of the project activities as required to the sponsor’s organization. 



The proposal evaluation process will be determined by the project advisor in conjunction with the CEDE, the project sponsor, and the CEDE Design Advisory Board.  It will be based on the organization of the project efforts reflected in the proposal and the educational goals achieved in the completion of the proposal.  Note that some efforts in the project are oriented to achieve educational goals that are not required to achieve the project sponsors goals.



This project has a variety of information from the sponsor available for the project team to review.



The sponsor has some drawings depicting the conditions at the work sites. In addition the project team will be required to make surveying measurements and to collect soils samples required for the design efforts.


The project team must familiarize themselves with the existing condition of the project in order to properly prepare the project proposal. 



The student project group will, at a minimum, provide the following efforts and deliverables in the completion of the project addressed in this proposal:
