Abstract | A methodology is developed for integrated and automated seismic damage assessment, cost estimating, scheduling and three-dimensional (3D) visualizations for postearthquake building rehabilitation. The proposed methodology relies on the development of software based on the integration of tools currently available to the Architectural, Engineering and Construction (AEC) industry such as Building Information Modeling (BIM), a fourth-generation programming language, a relational database management system and construction management tools within the framework for seismic damage assessment developed by the Pacific Earthquake Engineering Research (PEER) Center. This process provides automated generation of 3D damage assessment visualizations, cost estimation and schedule-of-work sequences for reinforced concrete moment-frame buildings, per element, element group, story and building, for specified levels of seismic intensity and given ground motion sets. Ultimately, BIM is enhanced with data about elements’ damage state, the expected rehabilitation cost and duration in the aftermath of an earthquake. Hence, engineers and developers have the unique opportunity to create a holistic picture of any RC moment-frame building’s seismic behavior, which is easily comprehensible by non-engineer owners, customers or shareholders.
