Challenges in technologies and innovations on maintenance operation of building envelope for high-rise building

High-rise building mostly designed in curtain walling confront with troubles during maintenance operation. A high risk in manual and semi-manual operation facing the issue in dealing with technology, expertise, equipment and environment collision is the main agenda of this study. Perhaps, this study will promote a new approach by reviewing the challenges in building envelope's maintenance operation in technologies and innovations for high-rise building. Nevertheless, some of the architects and engineers overlooked on its maintenance operation especially on building facade-cleaning works during design process. Thus, it has stretched an impact to the future maintenance workload and affected to others building maintenance aspects. Therefore, this research purposely to analyse on the difficulties in maintenance operation on building envelope faced by building maintenance management department, contractors, and architects through the closed interviews session. At the end of the research, the best practice of building envelope's maintenance operation on high-rise building is determined and this study may leads to the innovation opportunity and potential in maintenance operation for a better practice.
