Abstract/Summary
Construction Waste continues to be a major issue within the construction industry, affecting project costs, schedules, and environmental performance. A large portion of construction and demolition materials/ waste ends up in landfills. This is due to poor planning, limited worker training, and inefficient jobsite practices. This research-based senior project examines waste management efficiency on construction jobsites, while comparing and contrasting residential and commercial construction practices. The study evaluates how contractors manage material separation, recycling, reuse, and disposal of common construction waste. These include wood, drywall, concrete, metals, and packaging. A mixed-methods approach is used combining a review of academic and industry literature with jobsite observations and informal interviews with contractors in both sectors. The purpose of this research is to identify effective waste management strategies, understand why inefficiencies occur, and determine how successful practices used on commercial projects can be applied to residential construction. The findings suggest that commercial projects are more structured when it comes to waste management, while residential projects rely on informal practices that reduce efficiency. This research aims to provide practical, realistic recommendations that construction managers can implement to reduce waste, lower disposal costs, and improve overall jobsite organization.
