LCCA Training

DP 115 includes a two day workshop that provides technical guidance on best practice for conducting Life­Cycle Cost Analysis (LCCA) in pavement design. The workshop is intended for highway personnel with responsibility for conducting LCCA analysis of highway pavements. This may include State pavement design engineers, pavement management engineers, as well as, district or area supervisors with responsibility for selecting pavement type and rehabilitation strategies. The workshop incorporates the latest advances in multi-media presentations, computer simulations, example problems, class exercises, and group discussions.

The first day of the workshop focuses on traditional LCCA. It begins with background information supporting the need for LCCA and introduces the essential principles of the LCCA process. Discussion of the fundamental principles is followed by detailed discussion of each of the LCCA components (alternative development, costing, discount rates, work zone user costs, etc) and associated issues. Once this foundation is laid, the workshop moves on to several LCCA class exercises. The purpose of the exercises is to stimulate participation by workshop participants, as well as, reinforce LCCA computational steps.

Day two of the workshop introduces a probabilistic approach to LCCA. This approach utilizes a powerful analytical technique known as the Monte Carlo simulation to quantify the uncertainty associated with data inputs. The day begins with a refresher session on basic statistical concepts followed by an introduction to the probabilistic approach. These  fundamentals are followed by   demonstration of advanced risk analysis software  and a session of applying the probabilistic approach to a LCCA example. The day concludes with a discussion of the benefits and limitations of both the traditional and probabilistic based LCCA, and a discussion of steps to implement improvements in current LCCA procedures.

Each workshop participant is provided a Participant's Manual that includes all presentation material and a copy of the FHWA's Interim Technical Bulletin on LCCA in Pavement Design.
