Benefit/cost analysis as it relates to service life of geosynthetics
August 1st, 2020
On the surface, performing a benefit/cost (B/C) analysis is a straightforward process. However, ensuring that such an analysis is accurate and thorough is a much more nuanced task. In 2008, Bob Koerner laid out the procedure for geomembranes in Geosynthetic Research Institute (GRI) White Paper #12 “GS Selection Based on B/C Ratio.” This article expands […]
