Component State Criteria Representation to Incorporate Construction Program Knowledge for Constructability Analysis

Early consideration of construction sequence can benefit designers and constructors by reducing design iterations and smoothening construction flow. Capturing and representing the construction sequence knowledge is critical for the incorporation of construction programming experience into the project design and the communication between project participants. This study aims to present a common representation format for designers and constructors to study the interactive impact between product and process. The Component State Criteria (CSC) knowledge representation method is presented as a semantic format to capture and reuse construction sequence knowledge in the Product Oriented Scheduling Technique (POST) context. This representation format depicts the sequence knowledge from 3 different layers: component state chain, component interaction, and intermediate function utility. With the help of CSC knowledge incorporation, the intermediate function utilities for construction can be transparently represented. This study may help evaluate the impact of various construction methods and sequencing alternatives on the design, and consequently constructability analysis of AEC product design can be more explicit and efficient.
