“…Responses frequency of the most selected defects on electrical and plumbing systems In the plumbing system, leakage in water distribution elements (pipes) was the defect selected by 59.1% of the respondents, as illustrated on Table 5. Previous studies also identified that leakage at pipe penetration and joints are critical defects in the plumbing system [13]. Moreover, operational faulty functioning of water supply elements, which is related to problems with temperature, pressure, water level, vibration, was selected by 37.7% of the respondents.…”

“…Previous studies have focused on determining defects classification systems and defect analysis for specific building element or system, such as façade [24][25][26], wet areas [24], electrical and plumbing systems [13]. However, none of them propose a holistic assessment, they are incomplete and susceptible to misinterpretation, allowing for their inaccurate use, which requires an integration of a global analysis perspective [4].…”

“… Section 2: The second part contained several questions regarding the technical performance of construction elements and systems. A list of potential defects that might appear in each building element and system based on existing studies [10,13,22,24,[26][27][28][29][30][31] was provided to interviewees (see Appendix A). Interviewees were asked to select at most 3 main defects for each building element and system and it was given the option of adding other defects they considered relevant.…”

The technical performance assessment of a building is essential for planning maintenance actions to improve its condition and functionality. The aim of this study is to present a Building Inspection System to evaluate the technical performance of existing buildings. To do so, a questionnaire survey to identify the defects that majoritarily affect the technical performance of a building was conducted. The system was then validated in a university campus including 22 buildings. The results revealed three main applications of the proposed system: a comprehensive asset analysis, a building operating analysis and a risk analysis system.

“…The new structure was based on the definitions of "component", "elements" and "systems" made by NBR 15575 (ABNT 2013) and according to classifications found in previous studies on building defects (Berr 2016;Brito et al 2011;Chong and Low 2006;Das and Chew 2011;Forcada et al 2013;Georgiou 2010;Macarulla et al 2013). This structure also considered the warranty period of building components, as established by NBR 15575 (ABNT 2013).…”

Housebuilding companies are required to deal with customer complaints in the warranty period. Some of them have maintenance departments that make necessary repairs in existing buildings. Due to this service, companies accumulate records on the quality of projects, which can contribute to the understanding of occurrence defects and their causes, supporting continuous improvement. However, deficiencies in information management can make it difficult to use complaints records as a feedback source. The literature does not discuss solutions for managing information related to customer complaints, nor the use of performance metrics that can effectively provide feedback from quality problems identified. This study has two contributions: a classification structure for the types of defects identified from complaints, and indicators generated by fault tree analysis. The study was carried out in the maintenance department of a Brazilian housebuilding company. The evidence sources used were: complaint database analysis, discussion seminars, and interviews with the company representatives. The proposed solutions resulted in improvements regarding the structure and level of detail of the records. Also, the fault tree analysis made it possible to identify the most critical quality problems as well as to evaluate the level of impact of each one in project quality.

“…Buildings may have many sophisticated sensors and computerized systems capable of delivering data about the status and performance of its systems. However, building systems' condition are difficult to evaluate (Das & Chew, 2011;Douglas, Ransom, & Ransom, 2013). Few studies have analysed the major problems within building systems and there is little to no practical use regarding most of data collected from computerized systems (Pärn, Edwards, & Sing, 2017).…”

End users' maintenance requests gathered from computerized maintenance management systems (CMMS) configure a rich source of information to evaluate the occupants' satisfaction and the building systems. Nevertheless, the nonstandardized data gathered from CMMS makes it difficult to carry out analytics. This paper presents a text mining approach to extract information from end users' maintenance requests and an analysis of 6,830 maintenance requests derived from 46 buildings including offices, academic buildings and laboratories along two and a half years. The research results reveal that the most common maintenance requests during building operation and maintenance are related to problems in electrical and HVAC fixtures. Although the year of construction is not related to the occupants' maintenance requests, the type of building use and building property do influence them. The implementation of control and preventive strategies based on these results can increase facility managers' productivity and building systems' performance.
