Abstract
Traditional building quality management in the operation and maintenance (O&M) phase of the building life cycle has concentrated on inspection of quality defects by using new equipment or methods. However, there has been little research in terms of predicting a building's structural quality problems and suggesting related feasible maintenance solutions. This study proposes a two-level building quality decision support system (DSS) using the hybrid feature selection and least-squares twin support vector machine algorithms to predict structural damage types and damage causes and suggest maintenance solutions for a building. The basic-level building quality DSS model, which can be regarded a predictive maintenance system, predicts the probable changes in structural damage types over time as a means of reminding building maintenance practitioners to pay close attention to the most probable damage requiring maintenance at different times. The inspection-level building quality DSS model, which can be treated as a proactive maintenance system, predicts the probabilities of structural damage causes and suggests related maintenance solutions. This research can further enhance the accuracy of structural damage cause analysis and establish valid maintenance solutions for inspectors. In addition, it can help to optimize the design and construction processes of buildings, which will further decrease structural quality defects in the O&M phase.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
