| This dissertation addresses the need for a more flexible approach to the cost management method for building design and engineering in an increasingly competitive business environment of Japan. The building design processes are separated into three phases, Basic Design, Detailed Design and Supervision. In order to provide a budget in each design phase of every design function, the Delphi method was employed. Through a structured decision making process the phased budget for six major building types were defined and the results were compared with data from projects executed in the past. All data was gathered from the actual performance in the design division of TAISEI CORPORATION, one of the largest Japanese general contractors.;A decision management team was formed to conduct the Delphi decision making process. The expert panel consisted of fifty six managers who were experienced in the projects in various fields. Two rounds of the Delphi decision making process were conducted and significant results were obtained for six major building types, Offices, Hotels, Retails, Hospitals, R&D and High-Tech facilities and Residential establishments regarding a normative cost allocation procedure.;The findings are now being implemented by Taisei Corporation. |
