Computer integrated construction (CIC) has recently evolved to maximize the integrated utilization of information systems (IS) throughout the project's entire life-cycle and across different business functions. CIC is a broad and strategic concept as it is not a specific system. Complicating CIC solutions are the dynamics of business requirements and technology development. It is difficult, therefore, to design systems that are based on the available technology, resources, needs, and benefits. This situation calls for an effective CIC planning methodology, especially on a company level. This paper proposes a planning methodology that incorporates comprehensive issues for real-world CIC implementation. Measures and factors influencing IS assessment are investigated. In order to represent the complex measurements in a simplified manner, a CIC portfolio is also developed. Managerial issues are stressed throughout the planning process to help make CIC more viable and efficient. A case-study using this methodology is presented.
