Development of the Cost Baseline for Achieving Excellence in Rural Transit Facilities

Rural transit facilities have significant impact on annual transportation expenditures as these projects are usually numerous and geographically dispersed. Conceptual estimating of design and construction costs for these projects can be challenging, as there are insufficient information and documented data associated with rural transit facilities. Without an effective baseline for cost estimation during the early stages of the projects, it is unlikely that rural transit projects could be planned accurately and executed efficiently, possibly leading to major cost overruns. Therefore, the aim of this paper is to identify the major components of the rural transit facility projects, determine their design and construction cost estimating methods, and assess construction risk factors associated with rural transit facilities. Additionally, the regression technique is used to predict the design and construction costs of these projects. To fulfill the objectives of this study, comprehensive literature review was performed and an interview protocol was developed. The results of interviews with managers of Department of transportations (DOTs) were used to develop a structured survey questionnaire. Using collected 28 survey responses and case studies from rural transit facilities assisted in providing a baseline for estimating the design and construction costs of these facilities. The results revealed that projects’ size is significant predictor in the computation of the design and construction costs associated with rural transit facilities. The outcomes of this study provide a baseline for State Transportation Agencies (STAs) to evaluate the proposed bidders’ cost estimates and exclude unrealistic bid packages.
