Abstract: The construction requirements of a transportation project can be modeled and then evaluated for improving its constructability. The intermediate function concept has been developed for semantically representing construction requirements from the function perspective. This study develops the concept of spatio-temporal interaction matrix to capture the time-dependent spatial interaction between the user and the provider of an intermediate function, and meanwhile introduces another concept, spatio-temporal criterion matrix, for detecting unavailable spatial interaction required for supporting construction processes. Furthermore, this study also indicates that some non-collision conflicts residing in construction schedules can be identified using the detection method developed. The analysis result can aid planning engineers in identifying and resolving constructability problems. In addition, a simple case of supporting platform is used to demonstrate and validate the new concepts and the detection method. © 2010 ASCE.
