Life-cycle costing has become an essential component of any modern infrastructure design. It has long been realized that maintenance and rehabilitation costs, not just the immediate initial construction costs should be considered when evaluating investments in similar pavement alternatives.
As part of this project, Applied Research Associates, Inc. (ARA) developed a MS Excel based life-cycle cost analysis (LCCA) tool that quantifies and incorporates some of the stormwater management and quality benefits into the LCCA to compare permeable interlocking concrete pavements (PICP) to conventional pavements including off-road benefits.
