“…Previous works provided strategies for the conservation of historic buildings [1][2][3][4] and building rating systems [19][20][21][22][23][24][25][26][27][28][29]. In particular, methods for building condition and risk assessment, as a first step for maintenance planning, have been retrieved from Cecchi and Gasparoli [1].…”

“…Studies on this topic have been well highlighted by an interesting and recent literature review [19], which compares different methodological proposals [20][21][22][23][24][25][26][27][28][29] and reaches very interesting conclusions which validate the thesis of a substantial difficulty in simpli-fying and objectifying the problem: "There is lack of mechanism to prioritize the most vulnerable building components in existing building component rating systems. Future research in development of new building component rating system should focus on reducing or eliminating subjectivity from assessment.…”

A Methodological Approach for Assessing the Safety of Historic Buildings’ Façades

Inefficiency in maintaining and managing architectural heritage threatens both heritage conservation and public safety. Damage related to collapsed building elements requires an investigation into the factors which cause these phenomena in order to prevent them and to mitigate their effects. This paper aims to define a methodological approach for assessing the risk to humans of falling bodies from historic buildings’ façades. The method is based on the identification of a group of parameters to assess façade’s hazards, vulnerability and public exposure. The results provide the identification of risk factors and related affecting parameters, proposing a synthetic indicator to quantify the risk. The proposal is original in the field of both maintenance planning and preventive maintenance, intending to preserve architectural heritage and public safety. The results lead to an easy tool, as a map, to prioritise risk mitigation interventions. Such a tool, if integrated into maintenance tenders, allows the evaluation, in the context of condition-based maintenance, of the need for interventions.

“…Salim & Zahari, 2011 [19] Development of a building condition rating on a scale from 1 (highest) to 5 (lowest) that considers building type, building age, visual inspection, and the cost of repair Eweda, Zayed, & Alkass, 2015 [20] Space-based condition assessment model using analytical network process (ANP), analytical hierarchy process (AHP) techniques, and multi-attribute utility theory (MAUT) (six-point scale) Common characteristics of these studies include: (i) use of subjective and linguistic condition rating and index values; (ii) lack of considering multiple variables for CA; (iii) limited use of existing FM data, such as maintenance history, CMMS, or occupant feedback in the CA process; (iv) dependence of CA on expert judgment and visual inspection; and (v) lack of standardized and resource-efficient processes. In addition, limited efforts have been made to integrate structured multicriteria techniques, such as AHP, revealing the research gap of a standardized and quantitative process in CA and FM.…”

Condition Assessment Framework for Facility Management Based on Fuzzy Sets Theory

Condition information is essential to develop effective facility management (FM) strategies. Visual inspections and walk-through surveys are common practices of condition assessment (CA), generally resulting in qualitative and subjective outcomes such as “poor”, “good”, etc. Furthermore, limited resources of the FM process demand that CA practices be efficient. Given these, the purpose of this study is to develop a resource efficient quantitative CA framework that can be less subjective in establishing a condition rating. The condition variables of the study—mean time between failures, age-based obsolescence, facility condition index, occupant feedback, and preventive maintenance cycle—are identified through different sources, such as a computerized maintenance management system, expert opinions, occupants, and industry standards. These variables provide proxy measures for determining the condition of equipment with the implementation example for heating, ventilating, and air conditioning equipment. Fuzzy sets theory is utilized to obtain a quantitative condition rating while minimizing subjectivity, as fuzzy sets theory deals with imprecise, uncertain, and ambiguous judgments with membership relations. The proposed CA framework does not require additional resources, and the obtained condition rating value supports decision-making for building maintenance management and strategic planning in FM, with a comprehensive and less subjective understanding of condition.

“…Building condition assessment is being used for repair and maintenance decision-making (Abbott et al , 2007; NCES, 2003; Salim and Zahari, 2011; Straub, 2009). Condition assessment of the building is also used to decide rent and levy taxes according to the state of the building (Pedro et al , 2008) and for asset management (Dejaco et al , 2017; Eweda, 2012; Ho et al , 2008).…”

PurposeA building deteriorates over time due to aging, wear and tear, and inadequate maintenance. Building diagnosis requires a sound knowledge of engineering, building defects, and detection tools to assess the condition of a building. The physical deterioration of a building reduces its ability to perform its intended function, while environmental deterioration influences the comfort and health of building occupants. This study presents a multi-tiered framework for the inspection of building elements and the environmental conditions of a building.Design/methodology/approachA three-tiered building inspection framework is proposed in this study, which consists of the following: Tier-I—a preliminary inspection, Tier-II—a detailed inspection, and Tier-III—an expert investigation. Each tier of inspection assesses the severity of building defects using different technologies for different levels of inspection.FindingsProposed multi-tier inspection framework is tested and implemented on a case study. Results were promising, with organized data management on a common platform for both physical and environmental condition inspection having the potential to save time.Originality/valueThe application program developed for the implementation of structured multi-tiered building inspection provides better documentation and data management for building inspection data that can save time involved in manual data operations in traditional paper-based processes.
