Abstract: A building fa??ade performs the important role of weather exclusions to provide an artificial environment for work and play. A maintainable fa??ade is defined as a fa??ade that performs optimally and requires minimal maintenance of cleaning, repairs, replacements and inspections with maximum availability of services. An integrated methodology, comprising two main approaches of total quality management (via performance evaluation and audit) and life cycle cost, was proposed for quantifying the whole life performance of fa??ade. The research has taken into account the various tangible and intangible perspectives of fa??ade design, construction, maintenance and related risks that affect fa??ade maintainability and hence benchmark the level of fa??ade maintainability. In this study, 59 buildings in Singapore were evaluated to identify facade failures and establish the risk parameters that determine the defectsa?? extent of severity, probability of occurrence and risk exposure. Using multivariate regression analysis, a computational fa??ade maintainability scoring system via the use of multiple linear regression technique to represent a classification and predictive indication of the extent of maintenance necessary throughout its whole life was proposed to determine the facade maintainability scores as its performance evaluation. 29 risk parameters relating to fa??ade design, construction, maintenance practices, environment, quality and other intangible attributes such as competency of maintenance staff, customer satisfaction and quality of remedial process were analyzed and input into the fa??ade maintainability scoring model. The established maintainability assessment framework can serve as an essential and realistic tool for building professionals, owners and developers in the delivery of a maintainable fa??ade throughout their service life span right from the planning, design and construction stages.
