Abstract: Construction operations involve complex resource interactions and are typically performed in the field with exogenous factors such as inclement weather conditions and equipment breakdowns. The complexity of resource interactions combined with the external factors creates a transient environment for construction operations. This research utilizes computer simulation techniques and a graphical-based method, DISCO (Dynamic Interface for Simulation of Construction Operations), for the evaluation of the transient effects of construction operations. DISCO employs the CYCLONE schematic model diagram of a process as the modeling framework and provides the capability of allowing breaks or interruptions in the simulation run and stopping the simulation time clock to investigate the transient states of resources and tasks in a process. The scope of the study focuses mainly on the transient effects caused by the start-up development of construction operations every day. An earth-moving operation is used as a case study for the investigation. Results of the study and observations are discussed.
