The goal is to provide an adequate transportation facility at the lowest overall life-cycle cost. Life-Cycle Costs Include: Design costs Construction costs Right-of-way costs Routine maintenance costs Periodic maintenance and Rehabilitation costs Operating costs Accident costs Users' cost - Pavement smoothness - Foundation stability during construction - Tolerable post construction total and differential settlements - Hazards caused by maintenance operations and potential failures Inconvenience Environmental aspects Aesthetic aspects When all of these factors are evaluated, an alternative with a higher initial material or total cost, eg Geofoam, may prove to be the best alternative. NCHRP Document 65 (Project 24-11) Chapter 12-2 What is cost-benefit analysis? A cost-benefit analysis considers the intangible consequences or impacts of an alternative in addition to the tangible costs and benefits. These intangible consequences may be required to perform an adequate cost comparison. How do you incorporate cost-benefit analysis? To incorporating the intangible benefits into a life-cycle or cost-benefit analysis involves trying to quantify the benefits. For example, the benefit of reduced construction time can be ...
