THE STUDY OF ATTITUDES INVOLVES EFFECTS TO WASTE MANAGEMENT IN CONSTRUCTION PROJECT AND GUIDANCE TO WASTE MANAGEMENT IN CONSTRUCTION PROJECT

Abstract

The construction industry serves as a crucial driving force for Thailand's economic development and is a significant contributor to pollution issues. This is particularly evident in the waste generated from construction and demolition processes, which often comprises surplus or damaged materials resulting from work operations. This issue is prevalent in almost every construction project. This research aims to investigate the attitudes of stakeholders towards the impacts of waste management in construction projects and guidelines for waste management in construction projects. This study employs a quantitative research methodology, collecting data through questionnaires designed for three sample groups categorized by project type: high-rise building construction projects, residential building construction, and road and transportation infrastructure development. The collected data were analyzed statistically using frequency, percentage, Relative Importance Index (RII), and Factor Analysis (FA). The research findings identified six key factors: work and construction processes, budget and waste management procedures, attitudes and support for waste management, control, planning, and waste management policies, work experience, and internal organizational management. This research contributes to understanding the factors influencing the attitudes of respondents across different sample groups, which can be utilized as a guideline for developing effective waste management practices in construction projects.
