Investment Detail
The RWSL ROI is based on the cost benefit analysis conducted in preparation of the Baseline Change Decision (BCD) request presented to the FAA Joint Resources Council (JRC) on July 17, 2013. The benefits analysis, cost estimate, programmatic metrics, i.e., benefits/cost (B/C) ratio, the Net present Value (NPV), the Internal Rate of Return and the Payback Period were calculated to determine the financial benefits of RWSL at each airport and for the program as a whole. The individual airport benefit to cost ratio without sunk cost shows that of the 17 airports included in the BCD all but SFO provide a B/C of 1.0 or higher. San Francisco International Airport (SFO) is providing most of the cost for construction based on a Memorandum of Agreement (MOA) with the agency. The FAA is responsible for only $1.8M in construction cost at SFO. The internal rate of return is 10.5% without sunk cost and 2.2% with sunk cost.
