Advancements in computing have enabled the development of effective tools for the modeling and analysis of construction operations. In particular, recent developments in object-oriented and event-driven programming were used by the writers in the development of a hierarchical, modular, and graphical environment for simulation-based planning of construction projects. This system, termed hierarchical simulation modeling (HSM) method, is specifically geared toward modeling the uncertain nature of conditions under which projects are implemented and the dynamic utilization of resources in construction. The modeling concepts, internal structure, implementation, and working of this environment are described in this paper. ''Model definition,'' ''translation,'' ''simulation,'' and ''report generation'' are the four internal modules of this system. One of the key concepts highlighted in this paper is the use of an object-oriented paradigm for developing modeling objects that have ''graphics'' and ''simulation'' properties that allow development of an interactive graphical simulation modeling environment.
