A Review of Sustainability Indicators for Small-scale Construction Projects by Private Contractors

Abstract

Implementation of sustainable construction has become a prerequisite of the global construction sector owing to its cost, time, and waste management. Environmental, social, and economical sustainability indicators are key parameters for attaining sustainability in construction projects. It was inferred from the literature that sustainability in construction projects cannot be achieved without developing these indicators. Prior researchers used numerous statistical and mathematical approaches, such as fuzzy decision-making procedures and structural equation modeling, to develop sustainability in construction projects. Before creating a framework, significant research was conducted to collect important sustainability indicators in construction projects. This literature review examines papers published by reputable publishers, covering the most recent and important investigations. As a result, the current study's objective is to compile the necessary sustainability indicators and create a framework that can be used for small-scale construction projects. The previously established sustainability indicators for construction projects are identified in this present study. However, these indicators were only developed and identified for mega-scale construction projects. This study offers researchers suggestions for framing research for private contractors to achieve sustainability in small-scale construction works by using an integrated strategy to identify the research needs in this field. Sustainability must be incorporated in small-scale construction projects from the beginning of planning and administration, which must be monitored throughout the project
