| 摘要： | The purpose of this project was to research long-range (parametric) cost estimation at the Colorado Department of Transportation, utilizing AASHTO's Trns.port Cost Estimation and Decision Support software. Info Tech, Inc. analysis reviewed CDOT's current long-range estimation practices and identified revisions which would be needed to satisfactorily meet CDOT's future cost estimating requirements, i.e. in order to develop consistent and reliable cost estimates when little is known about a project. Both item and contract classifications utilized by CDOT in BAMS/DSS were revised to reflect more logical functional groupings. The new contract work type and item classification were used directly to develop in Interim Solution for Long-Range Cost Estimation that uses historical bid-based default prices. Info Tech analysts also researched Internet sources to identify the availability of major item cost data at the regional and national level, including data for multi-modal project types. Overall, given the absence of historical data available, it was not possible to evaluate outside data compatibility with CDOT data. The corollary to this research project is for CDOT to move forward with implementation of AASHTO's Trns.port Cost Estimation System (CES). The new CES is currently in the warranty phase, which will be completed by September 30, 2000. |
