Constructability information classification scheme

This paper discusses the development and testing of a generic model that classifies constructability information for reinforced-concrete structural elements. It identifies decisions and factors affecting constructability and classifies them in a constructability information model (CIM). This model is tested with concepts from the literature and an industry survey. A refined structure is developed and evaluated for future work. The resulting CIM is a hierarchical breakdown of constructability concept attributes grouped in categories and subcategories. The major categories include design rules, lessons learned, external constraints, resources constraints, and performance information. Each concept is further classified by associating it with the facility processes and products that it affects. The CIM is found to be useful within the limits of its testing; reinforcedconcrete structural elements. Further classification refinements are required to improve information storage and retrieval efficiency.
