An important aspect of construction project control is accurate development of a baseline schedule. It becomes the standard against which all progress and performance is measure. Knowledge-Based Expert Systems (KBESs) offer promise of helping managers control projects better. Research at U.C.Berkeley is being conducted to utilize this tool. Concepts necessary for an Automatic Construction schedule Generator are described in this article. The prototype outlined in this paper works from CAD-type information to form a milestone schedule. The goal is to design and implement a system that prototypes a planning system for construction. In addition, the argument is made here that understanding and interpreting qualitative information is crucial to a realistic system. We then go in to describe work aimed at incorporating an approximate reasoning facility into the underlying KBES.
