摘要：	This final report summarizes the activities that took place on a design-build project in Region I of Colorado Department of Transportation (CDOT). Under the Special Experimental Project No. 14 (SEP 14), FHWA approved the design-build concept to be used for the 12 miles reconstruction of 1-70 east of Denver. Included in this report is an overview of the design-build concept, discussion of significant events and results of a questionnaire on design-build methodology. Also, included in the report is description of all the construction modification orders (CMO) and discussion of quality control quality assurance processes. The ultimate goal of this study was to identify and document the pros and cons of the design-build practice and to examine its overall applicability to CDOT. Implementation The use of design-build methodology for- awarding construction projects looks promising. However, there is room for improvement in a fully implemented design-build concept When early completion of a project is of significant value, the design-build method of project delivery becomes very attractive. CDOT pursuance of the best value concept along with extended warranties for larger and more complex projects is a step in the right direction. The passage of the House Bill 99-1324 will now authorizes CDOT to award contracts to the contractors who provide the best value offer. In addition, this bill also authorizes CDOT to include a warranty provision that requires the design-build firm to perform maintenance services on the completed transportation project
