Estimating Life-cycle Cost of West Virginia Fiber Reinforced Polymer (FRP) Bridge Decks
Life Cycle Cost Track
The main objective of the research was to study the economic viability of West Virginia Fiber Reinforced Polymer (FRP) bridge decks. Life‐cycle cost of those bridge decks were estimated for conducting such analysis. Three main differences that distinguish the way the life‐cycle cost of FRP deck was estimated are: (1) the manufacturing cost of a FRP bridge deck was estimated using learning curve theory; (2) cost savings in support structures when FRP is chosen as opposed to the alternative bridge deck was modeled; and (3) the service life was estimated based on factor method to minimize the subjectivity of the estimates. The three case studies for West Virginia FRP deck projects show that based on the estimated life‐cycle cost, FRP decks are financially viable under certain conditions

Sidharta Sahirman holds Magister Sains (MSi) degree from Bogor Agricultural University as well as Master of Science in Industrial Engineering (MSIE) degree from University of Pittsburgh, PA. He received full scholarships for both degrees. Recently he received his PhD in Industrial Engineering from West Virginia University (WVU). Since coming to WVU he has served as a graduate research assistant for Center of Excellence, School of Engineering and Mineral Science, West Virginia University. He has written several papers based on his research funded by a FHWA project. His paper has been recognized with a 2003 SCEA/ISPA Joint Conference Award – Best paper in Methods Track.
He joined Jenderal Soedirman University as a faculty member, after working for several years in industrial settings. He has worked as the General Manager of Gadjah Wisesa Utama – a Forestry, Agriculture, Hatchery company based in Jakarta, Indonesia after spending one year as an Engineering Division Manager of Puspeta Cooperation Company, Klaten, Indonesia – which is funded by the Cooperative League of USA. His professional career outside of academia is a cost engineering consultant.
He loves travelling, fishing, and golfing. An important aspect of his life is the family — his wife (who holds a PhD from the same school), his kids and his beloved late father and mother. He is a devoted husband of eight years to the lovely Bina R. Setyawati-Sahirman.
