Scheduling with Computer-Interpretable Construction Method Models

This paper presents computer-interpretable models for the representation of construction methods. These models support the automated generation of realistic construction schedules. They are activity based to support the selection of meaningful activities and to link schedules at various levels of detail. Five attributes define a construction method: Domain, Constituting activities, Activity sequencing, Constituting objects, and Resource requirements. These construction method models act as a template to capture production knowledge specific to firms and projects. We illustrate the use and implementation of these models by scheduling the construction of masonry walls. These models assist architects, owners, and contractors in studying cost and schedule implications of a large number of design and construction alternatives.
