Quantitative Analysis Of Building Construction Project Management And Waste Production Strategies In Highly Urbanized Cities Of Surabaya: A Case Study Of Kalidami Street Office

Abstract

Surabaya is a second densely populated city with high-rise developments, and its construction waste generation is increasing annually. Existing landfills should be allocated properly to support the development, including the office building area. In fact, the current famous location for office location is centre nearly to the Kalidami street and mostly waste product from the construction development are coming from the project of that area. In Construction waste management in Surabaya has been implemented for years with mixed results. To investigate and formulate strategies and measures for effective construction waste reduction in highly urbanized cities. Furthermore, building waste has a negative economic impact by adding to the cost of construction due to the requirement to replace discarded materials. However, in order to reduce waste, construction managers must investigate management methods such as trash reduction, recycling, and disposal. Reduction is the highest priority among waste management strategies, but effective reduction cannot be achieved without a thorough understanding of the trash's origins. As a result, the goal of this work is to report the findings of a study on the contribution rates of 18-recognized sources of construction. Establishing the contribution rates of various waste sources will improve knowledge-based decision-making in designing an effective plan for construction waste mitigation. This study used a quantitative research method, a survey questionnaire, to analyse the frequency and severity of contribution of waste sources. One of the study's conclusions was that residual waste, was the largest contributor to construction trash. As a result, this study indicated that trash contributes significantly to building costs.
