“…The panel is made up of six experts with no less than 15 years of relevant experience, representing development and a construction companies, engineering and architecture studios, a collaborating mutual society and the body of labour inspectors. Although the sample size is small, several studies have pointed out that panel size is not a limitation, as AHP can be conducted with a small number of participants to achieve sound and statistically robust results [84][85][86]. These experts act as decision makers, making their consensual value judgments on the pairwise comparisons of the modelled AHP problem.…”

At present, it is striking that a large percentage of occupational accidents in the construction sector are still caused by falls from height. Therefore, curbing the severe personal, social and economic consequences of these events is not only a commitment but an obligation for all stakeholders in the construction sector. After a review of current fall protection systems on construction sites, the purpose of this study is to establish the preliminary requirements for the design, development and prototyping of a new system which can be used as an auxiliary means to prevent occupational accidents in the construction sector caused by fall hazards at height. Based on the design science research (DSR) methodology, this paper tests the capability of alternative materials (metals, plastics and composites) to withstand the loads required by the regulatory standard UNE-EN 13374:2013 + A1:2019 and looks at the improvements they can offer. The results obtained enable new metals and composite materials to be put forward, based on their suitability to the parameters of the risks of falling from height, ensuring that the greatest number of potential situations are addressed. Then, the needs to be satisfied and requirements to be met are listed, prioritised and considered for new temporary edge protection systems (TEPS). Next, the attributes that increase user satisfaction and/or reduce user dissatisfaction are filtered by means of a Kano model, which is applied thanks to the responses of construction designers, coordinators and supervisors. Once these questions are solved, an analytic hierarchy process (AHP) is performed by a focus group, weighing the Kano contributions and ranking the materials to be selected for the preliminary design of innovative TEPS for construction works. After considering safety, ergonomics, adaptability, sustainability, efficiency, manufacturability and flexibility criteria, the basis for the design of a new temporary edge protection system is established.

“…Besides, this method has been used by several studies to check the reliability of the collected data from a small sample size (Salman et al 2007, Doloi 2008, Akroush and El-adaway 2017, David and Varghese 2021. Finally, the findings from the data analysis were compared with the findings of two studies in the literature.…”

Non-destructive testing (NDT) methods are typically utilized to thoroughly inspect existing defects in the concrete bridge deck and tackle the limitations of common inspection practices (e.g., visual inspection). Nevertheless, the reliability of inspection outcomes crucially depends on choosing the most appropriate NDT technologies. In this regard, a comprehensive Performance Assessment Model (PAM) was developed. The developed model incorporated 40 parameters to precisely assess the performance of different NDT technologies from diverse perspectives (e.g., defect detection capability, ease of use, speed, and cost). The required data were collected through a survey questionnaire. The model utilized the Analytic Network Process (ANP) technique to calculate the importance weight of each parameter, whereas the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) was exploited to compute the performance index (PI) of NDT technologies. The outcomes of this study clearly illustrate the disparity in the performance of different NDT technologies. Furthermore, it was shown that none of these technologies could either exhibit the best performance in all the proposed parameters or efficiently identify all types of defects. Based on the PAM results, a selection model was proposed to assist bridge authorities and consultants in choosing the most efficient NDT technologies for inspection purposes.
