Abstract: Pre-project planning is the project phase encompassing all the tasks between project initiation to detailed design. The development of a project scope definition packages is one of the major tasks in the pre-project planning process. Project scope definition is the process by which projects are definedand prepared for execution. It is at this crucial stage where risks associated with the project are analyzed and the specific project execution approach is defined. Nevertheless, the pre-project planning practices vary significantly throughout the industry from one organization to another. Pre-project planning practice data from 62 industrial projects and 78 building projects, representingapproximately $5 billion in total construction cost, were collected and pre-project planning practices (as measured by the level of scope definition) were analyzed. Poorly defined scope elements among the surveyed projects will be identified and compared between the two industry sectors. The pre-project planning practices among successful and less-than-successful projects will be compared.

INTRODUCTION Significant decisions are made by the project team during the early planning phase of capital facility project developments. The process of pre-project planning constitutes a comprehensive framework for detailed project planning and includes scope definition. Project scope definition, theprocess by which projects are selected, defined and prepared for definition, is one key practice necessary for achieving excellent project performance [1] and is a key element in the pre-project planning process. How well pre-project planning is performed will affect cost and schedule performance, operating characteristics of the facility, as well as the overall financial success of the project. [2]The construction industry has recognized the importance of scope definition during pre-project planning and inadequate or poor scope definition, which negatively correlates to the project performance, is among the most problems affecting a construction project. [3] Due to poor scope definition, final project costs can be expected to be higher because of the inevitable changes which interruptproject rhythm, cause rework, increase project time, and lower the productivity as well as the morale of the work force. [4] Nevertheless, the pre-project planning practices vary significantly throughout the industry from one organization to another. In order to investigate the pre-project planning practices in the construction industry, a scope definition tool, Project Definition Rating Index (PDRI) isincorporated in this research. Researches conducted by the Construction Industry Institute (CII) have developed the PDRI to address scope definition in pre-project planning for both the industrial and building sectors. The PDRI is a comprehensive, weighted checklist of crucial scope definition elements that have to be addressed in pre-project planning process. It provides the project team asimple and easy-to-use tool to objectively evaluate the current status of a project during pre-project planning. Since its development, researchers at the University of Texas at Austin and CII have been collecting pre-project planning information using the PDRI. The PDRI was used to collect information of the pre-project planning practices in the industrial and building industry. The similarities and...
