Home Work. (Show your work) Washington State Department of Transportation (WSDOT) utilized RFP to procure a design-builder for an interchange project located in Vancouver, WA. The SR 500 Thurston Way Interchange is a redevelopment of the "at grade" interchange of SR 500 and Thurston Way, which is located in the WSDOT southwest region. The project lies between the SR 500 Andresen Road Interchange and the SR 500 1-205 Interchange has an estimated cost of $10,000,000. The proximity of the project is in a tight corridor that creates many challenges as well as opportunities for alternative and innovative approaches in addressing the traffic flow logistics during construction. Traffic volumes on the main route, the proximity of the main entrance to Vancouver Mall and another plaza on the south side, along with challenging weaving requirements, made this a challenging project. WSDOT included key personnel, management plan, schedule, and technical solutions as part of the technical component of proposals. The technical component of received proposals was reviewed to determine if the proposal is responsive or not. For weighted score, 25% is given to technical proposal and 75% is given to financial proposal. Five contractors submitted their bids based on the advertised RFP as shown in the table below. Use the information to select the contractor based on best value (adjusted bid, adjusted score, weighted total score, and time plus cost) methods. Show all your work.
