ECO-CONSCIOUS BUILDING BLOCKS: THE ADVANTAGES AND DISADVANTAGES OF A SUSTAINABLE APPROACH TO MATERIAL SELECTION FOR INFRASTRUCTURES AS PERCEIVED BY SELECTED CIVIL ENGINEERS IN DISTRICT IV, NU

Abstract

Material selection is among the top issues influencing the success of sustainable construction and long-term development. Choosing sustainable construction materials is critical in reducing environmental impact and ensuring that infrastructure remains viable for both present and future generations. Thus, this study was conducted to determine the perceptions of selected civil engineers regarding the advantages and disadvantages of using eco-friendly materials in infrastructure projects. This study employed a descriptive research design using a qualitative approach. Participants’ perceptions were utilized to collect and analyze information relevant to the objectives of the study. The population consisted of civil engineers from District IV, Nueva Ecija, with ten (10) civil engineers selected as participants. Data were analyzed using descriptive and thematic coding, with themes and indicators developed to interpret the findings. The study examined civil engineers’ perceptions of various eco-friendly materials, including wood, recycled metal, recycled plastics, and alternative concrete materials. The findings revealed that the primary advantages of eco-friendly materials include sustainability and reduced environmental impact. However, several disadvantages were also identified, particularly issues related to availability and cost. Due to limited public awareness, civil engineers recommended stronger promotion of eco-friendly materials by emphasizing their benefits, such as lower environmental impact and reduced construction time. Designing infrastructure that incorporates sustainable materials was also identified as an effective way to encourage adoption among professionals and the public. The findings indicated that eco-friendly materials offer significant advantages in the field of civil engineering, particularly in promoting sustainability, durability, and reduced environmental impact. However, current infrastructure practices and modernization trends continue to limit the widespread use of eco-friendly materials, with a stronger focus placed on conventional materials. Addressing these limitations through awareness, promotion, and design innovation may increase the adoption of sustainable materials in future infrastructure development.
