All buildings deteriorate over time. If neglected, the severity of their deterioration and the repair work required increases. The deterioration of buildings, however, can be slowed with ongoing maintenance. This research created an informative, user-friendly, and uniform workflow that can ensure the ongoing maintenance of buildings, with Header House as a case study. The framework begins with research and surveying the building. As-built and condition drawings and a BIM are produced. A seismic analysis was also conducted for a range of values and connectivity conditions. The drift of the building was not sensitive to these range cases, while the acceleration and base shear were affected by the change in stiffness. The results determined that Header House requires no seismic interventions. A monitoring program and maintenance plan were then created based on the information gathered. The process is repeated every five years to ensure that the building continues to be maintained.
