Value Analysis. The National Highway Systems Act and the Safe Accountable Flexible Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) require a project with a total cost of $25 million or more to have a Value Analysis study prepared. The Value Analysis (VA) study was conducted in September 2020, and three VA alternatives were developed: Alternative 1.0: Construct the project with a 10-hour nighttime construction period in lieu of an 8-hour nighttime construction period. This alternative would reduce working days and project cost, however there will be inconveniences for motorists Alternative 2.0: Improve slope protection to avoid needing a 404 permit and save National Pollutant Discharge Elimination System (NPDES) cost. Alternative 3.0: Reduce the pavement replacement depth from 0.6 feet to 0.35 feet. This alternative would reduce project cost. Extending closure hours may not be feasible based on latest traffic operational trends, 404 permit requirements may not include slope protection conditions, and quality of pavement may not allow for a reduced replacement depth that can accommodate a 20- year pavement life. It was determined that additional analysis is required during PS&E phase to determine feasibility of these alternatives. Final determination is scheduled for February 2022. Current scope assumes these alternatives are not implemented.
