The concept of "constructability" has been raised to optimize construction knowledge and experience in the design phase of construction projects to improve project performance. Previous research demonstrated the feasibility of an automated, rule-based constructability review through BIM implementation. The current work investigates the elicitation of constructability knowledge to achieve the automated process. With a case study, two frequently used knowledge elicitation methods—interview and document analysis—were applied to collect constructability knowledge on formwork selection for a concrete building project. Advantages of each technique indicate the need for combining the two elicitation methods as a means of triangulation to establish a comprehensive and accurate knowledge base for an automated, rule-based constructability review.
