GIS-Based Decision Support System for Safe and Sustainable Building Construction Site in a Mountainous Region

Abstract

The site selection process for a building entails evaluating a variety of factors with varying degrees of importance or percentage influence. In order to ensure that critical site selection factors are not overlooked, a methodology for calculating a building’s safe site selection must be developed. The study identified three broad aspects widely considered in site selection, namely environmental, physical, and socioeconomic criteria. To assess the safest site selection of residential building construction for sustainable urban growth, we used GIS-based multi-criteria decision-making approach that combined Fuzzy-AHP and weighted linear combination (WLC) aggregation method used to calculate the SSPZ. The final safe site suitability map was generated by aggregating all aspects such as geophysical, socio-economic and Geo-environmental thematic layers and their associated Fuzzy-AHP weights using the weighted linear combination method. The sites potential index’s mean value of 0.513 with standard deviation of 0.340, minimum and maximum GeoPhySSSI are 0.0 and 0.91, respectively, SSS index is classified into zones by histogram profile using natural breaks (jenks)” Subsequently, safe sites identified and divided into six classes namely no construction, very low suitable site low suitable site, moderate suitable site, high suitable site, and very high suitable site.“ According to the statistical analysis, 3.64% and 32.12% of the total area were under very high and high SSSZ, while 26.40% and 6.22% accounted to the moderate and low suitable potential, respectively” Our findings suggest that integrating the fuzzy collection with AHP is highly desirable in terms of alternative and decision-making effectiveness. The study reveals that the areas of high and moderate suitability are located near existing habitant area, major roads, and educational and health services; they are not located in restricted/protected areas or are vulnerable to natural hazards. The findings indicate that unsuitable and less-suitable land uses such as vegetation, protected areas, and agriculture lands cover nearly one-third area of Abha-Khamis Mushyet regions, implying that using Fuzzy-AHP and GIS techniques will significantly aid in the conservation of the environment. This would significantly mitigate adverse effects on the ecosystem and climate.

“…FL can deliver quick, streamlined and effective responses, but stability analysis cannot be performed using FL, and it is difficult to predict the outcome in advance (Mastrocinque et al ., 2022). Fuzzy set theory's characteristics of relativity, variability and inexactness enable it to accommodate imprecise information that provides more than one specific solution (Mallick et al ., 2022). However, it is difficult to choose an appropriate set of rules with which to get accurate solutions using fuzzy set theory (Llopis-Albert et al ., 2022).…”

“…All the more explicitly, as revealed by the European Commission (Tamilenthi et al 2011), real estate projects are liable for around 40% of energy utilization and 36% of CO2 discharges in the European Union. Mallick et al (2022) developed a methodology for estimating a building's safe site selection by evaluating a variety of factors in order to assess the safest location for residential building construction for sustainable urban growth. The study identified three broad aspects, namely environmental, physical, and socioeconomic criteria.…”

“…The land use suitability analysis essentially took into account various criteria based on sustainability factors such as physical, environmental, social, and economic constraints, among others (Rajnoha & Lesnikova, 2016, Mallick et al 2022, Yan et al 2021, and Charpin, 1978. These factors are widely supported in literature and tend to impact on how sustainable a construction project is based on its ability to employ materials that are cheap and can be easily recycled, for example, or improve the quality of life of people and understand the physical conditions of the ground or terrain in order to gather relevant information that will be useful in trying to minimize environmental hazards, etc.…”

“…However, whenever left uncontrolled, it tends to adversely affect ecological degradation, prompting an imbalance in land use and a shortage of its assets. Spontaneous urbanization prompts infrastructural facilities and a poverty condition (Mallick et al, 2022). Whereas the Nigerian government housing authorities (NHP) and the Central Bank of Nigeria (CBN) have identified finance as the major impediment to meeting the housing needs of its evergrowing urban population (Emmanuel A.M., 2019).…”
