Architecture, engineering, and construction (AEC) teams need more efficient and effective decision-making methods, particularly in the pre-construction phase when decisions have the most significant impact on building performance. This paper discusses the selection and application of decision-making methods for the preconstruction phase of a lean corporate campus project. Findings are based on the project team’s review of several value-based decision methods and final selection of the Choosing By Advantages (CBA) approach. CBA was implemented first using group preferences, then with simple additive weighting of individual preferences. In general, decision makers found that CBA enabled multi-disciplinary stakeholder participation and added value to decision-making for simple decision problems. However, decision makers also believed that CBA was inefficient and ineffective for more complex decision problems and did not adequately clarify decision rationale. Switching to individual preferences improved efficacy, efficiency, and value of information derived from the decision-making process, but clarity of rationale remained an issue due to the inherent complexity of decision problems and inconsistencies in factor selection between decisions. These observations suggest the need for future research concerning the design and implementation of appropriate tools for pre-construction decision-making on lean projects.
