An interactive training model called SAVR (Safety in Construction Using Virtual Reality) was developed to train construction students, novice engineers, and construction workers to prevent falls from scaffolding. The model was implemented in a graphics supercomputer, the ONYX Reality Engine2. The SAVR model provides trainees with an immersive, interactive virtual environment to perform "on-the-job" safety training without physically being at a real construction site. The model includes two major training environments: erection, which teaches trainees the correct procedure to erect a commonly used metal bracket form scaffolding; and inspection, which introduces several hazardous conditions in an existing platform and requires trainees to identify them visually. The development of SAVR involved four major tasks: knowledge acquisition, model development, model validation, and preparation of reports and manuals. Several common potential causes of falls from scaffolding platforms were chosen for the SAVR model, including component problems and connection problems. The second task, model development, included the construction of the three-dimensional graphical objects of the scaffolding components, the construction of the texture images for SAVR's interface panels, and the construction of the SAVR program. Construction used a developmental approach that included six steps: (1) defining the problem, (2) designing the solution, (3) refining the solution, (4) considering a testing strategy, (5) coding, testing, and debugging the program, and (6) documenting the program. SAVR demonstrates the potential of virtual reality technology in safety training using a safe environment. (Contains 45 references.) (KC)
