Twin Bridge Replacement on I-90 Business Loop, River Street, in Mullan, Idaho
This RFP IS FOR BOTH CIVIL 3 (Hydrological & Hydrolic) & CIVIL 4 (Structural)
Due Friday, September 28, 2012
CEDE - Civil Engineering requests a student project proposal for the following project:
Twin bridge replacement, including hydraulic and scour design, structural and foundation design, and a roadway corridor design for the I-90 Business Loop, River Street, in Mullan, Idaho.
Due September 28, 2012, before 4:00 PM PST
One digital copy in pdf format and one hard copy of proposal must be submitted.
Location for Proposal Delivery:
Assistant Director for CEDE,
Gonzaga University School of Engineering and Applied Science,
PACCAR 214, Spokane, WA 99258.
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 structures. The project will include an evaluation of the hydraulics of the South Fork of the Coeur dâ€™Alene River using HEC-RAS to size the bridge openings and ensure that all FEMA floodplain regulations are met. A structural analysis and design must be completed for the replacement structures to ensure that they can support the necessary loadings. A foundation design for each bridge replacement structure must also be completed considering the bridge loadings and the hydraulic scour analysis results. Finally, due to the location of the two bridges being in close proximity and within the city of Mullan, a transportation design of the I-90 business loop (River Street) corridor connecting the two bridges must also be completed.
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.
The proposed project is to replace two bridges crossing the South Fork of the Coeur dâ€™Alene River on the I-90 Business Loop, River Street, in Mullan, Idaho. The bridges are located approximately 1200 feet apart as the South Fork winds its way through the city of Mullan. The upstream bridge is located near River Street and 7th Street and the downstream bridge is located near River Street and 3rd Street. The existing concrete, two span, bridges are on the route that was previously the main highway. The existing bridges are cast-in-place structures with each center pier located on the east edge of the South Fork. The two existing bridges are in the current transportation improvement program for bridge replacement. ITD Bridge No. 17375 is programmed for FY13 and ITD Bridge No 17380 is programmed for FY14, although the intent is to companion the two projects for design and replacement in FY13.

Scope of Activities Required to Meet Sponsors Goals
Task 100 Project Management and Coordination
The student group shall organize, manage and coordinate the efforts required to accomplish the project using standard project management and contract administration techniques. Key management activities are identified below:
Sub-Task 110 Kick-off Meeting
The Student Team will conduct a kickoff meeting with their project advisor and liaisonâ€™s to gain familiarity for the project and to solicit input, gather available data and information.
Sub-Task 120 Additional progress-review meetings
Additional progress-review meetings will be conducted on a regular basis as follows:
a. Weekly mini-progress reports are required and are to be submitted electronically to the advisor by 5:00 pm each Thursday. Mini-progress reports must include, at a minimum, activities completed by each team member for the current week, expected work for the upcoming week,
b. In addition, a complete hardcopy record of the project reports and files must be maintained by the student team and be made readily available during consultations with the advisor. Typical method would be a project notebook. The advisor and liaison will ask to review this notebook periodically to discover the status of the work being completed.
Sub-Task 130 Regular Advisor and Liaison Meetings
After the kick-off meeting, the Student Team will meet weekly with the project advisor, and will also meet when needed with the project liaisons. All meetings with advisor and liaisonâ€™s MUST be arranged by members of the Student Team in advance (at least 2 days prior) and include a proposed meeting agenda sent to the advisor or liaison prior (at least 2 days) to the meeting. All meetings must be documented by the Student Team in the form of meeting minutes with copies distributed within 3 days of the meeting to all team members and the project advisor and liaisonâ€™s, as above.
Task 200 Project Data Collection -Site Visit
Participate in initial site visit to project locations. Work collaboratively with project liaisons, State of Idaho contacts, and regulatory agenciesâ€™ staff to develop project data suitable for a preliminary design. Data could include soils, geology, site survey, traffic counts, hydrologic, hydraulic and other data. Proposal submitted is to identify data needs and collection methods for the project.
Sub-Task 210 Stream and Basin Characterization
Stream Survey and Topography, Bed and Bank Soil Characterization, Stream Stability and Hydrologic and Hydraulic information required to make calculations in the HEC-RAS model of the project.
Sub-Task 220 Structure Evaluation
Geotechnical Investigations for Foundation Design
Sub-Task 230 Transportation Evaluation
Traffic, access and transportation planning information.
Task 300 Project Preliminary Design
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 structures. 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 structures based on initial cost, expected loading, constructability, environmental concerns, and future maintenance costs.
The Design Team should evaluate the hydraulics of the South Fork of the Coeur dâ€™Alene River using HEC-RAS to size the bridge openings and ensure that all FEMA floodplain regulations are met (hydrology, existing conditions model and calibration, proposed conditions model, bridge opening design, scour analysis and countermeasure design).
A structural analysis (live, dead, wind, and earthquake loads) and design (deck and girder design) should be completed for the replacement structures to ensure that they can support the necessary loadings.
A foundation design for each bridge 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, due to the location of the two bridges being in close proximity and within the city of Mullan, a transportation design of the I-90 business loop (River Street) corridor connecting the two bridges should also be completed (traffic study, sidewalk design, roadway alignment, pedestrian crossing designs, pavement design, stormwater design, and signage placement).
Task 400 Project Permitting Data
The Student Team will initially be asked to conduct an investigation into the pertinent codes and regulations. They will be asked to summarize the mandatory codes and regulations that are relevant to this project. In addition, they will also be asked to summarize the recommended codes that could possibly apply to this project. All these codes and regulations must be followed.
