The subject of this paper covers a project that was successfully commenced in 1997 and completed in 1998. This paper discusses the development of a method to use network level PMS data for a project level life cycle costing analysis. The method was successfully applied to a variety of road conditions and structures that make up the primary highway network in Saskatchewan, Canada. This project followed on from a project that implemented probabilistic and deterministic network level PMS within Saskatchewan Highways and Transportation. The project that is the subject of this paper was to determine the whole of life implications on level of service for different funding scenarios on different types of road structures. The paper briefly discusses the details of the method identified and the network level data that was used. The paper specifically focuses on: (1) Description of the network level probabilistic cost/deterioration models; (2) Description of network level deterministic deterioration models; (3) How the models were combined to develop a deterministic project level deterioration versus maintenance cost model; (4) Application of the project level models in life cycle cause and effect models; (5) The method used to analyse the above to develop net present worth and equivalent annualised cash flow for different level of service starting case scenarios.
