The environmental consequences of construction and demolition waste in the U. S. are staggering. With more than 1. Understanding Canadian Public Administration Ebook here. Reducing the amount of waste in a project is an important part of sustainable building and begins with the design process. Choosing alternative methods of construction such as prefabrication, modularization, and off site construction techniques is an effective way to design out waste reducing the overall construction waste during construction vs. AIACESLearning Objectives To earn one AIACES learning unit, read this article and the test questions, then submit your answers by clicking the Submit Test Answers link at the bottom of this page. Understand that construction and demolition waste can be lessened even before on site work begins, when designing out waste in early stages of construction. Learn how alternative methods of construction like modularization, prefabrication, and offsite technologies are particularly effective ways to manage waste. Recognize that designing whole buildings for reuse at the same or different locations is a more sustainable concept than abandoning or demolishing buildings. PRINCIPLES OF BUILDING CONSTRUCTION COMBUSTIBLE xi COURSE OVERVIEW Module 1 This module is an introduction to building construction principles and classification of. Construction Principles Materials And Methods Pdf' title='Construction Principles Materials And Methods Pdf' />Interactions commitments. Learn how using controlled environments to construct buildings can help projects be healthier, safer, and more environmentally friendly. Green building efforts for site built construction focus on reuse, recycling or diversion of waste that is generated on site. PXZOj19.jpg' alt='Construction Principles Materials And Methods Pdf' title='Construction Principles Materials And Methods Pdf' />With off site construction, however, the materials can be managed prior to leaving the factory, offering a much more efficient process to reduce the amount of waste sent to landfills. Left Waste hierarchy showing that the target for any waste reduction strategy is to first design out waste, and then focus on recycling and reusing any remaining waste material. Data courtesy the U. K. Waste Resources Action Programme WRAP. Due to the factory controlled process, modular construction is by nature material and resource efficient. One of the great economies of modular construction is the ability to assemble repetitive units in controlled conditions. Another is to minimize material waste associated with conventional construction due to weather intrusion and construction site theft. Whole modular units largely finished prior to arriving at the construction site can significantly limit construction waste generated at the site and contribute directly to construction site waste management. Modular construction capitalizes on the ability to move product in controlled manufacturing conditions, and on tight inventory control and project schedules. Since the 1950s, lean production or Toyota production system principles have evolved and were successfully implemented by Toyota Motor Company. Accreditation. Our accreditation sets the global standard for programs in applied and natural science, computing, engineering, and engineering technology. Green Building Materials Flooring Wall Finishes Cabinetry Solid Surfaces Tile Insulation. Construction of low volume sealed roads good practice guide to labourbased methods international labour organization dwt country office pretoria. It is inherently waste conscious and can have minimum site impact if delivered carefully and strategically with respect to site constraints. In addition, since modular builders work in a factory controlled environment, they can have many construction projects underway simultaneously in one location, so they are better able to re inventory materials that may have been allocated to one project, for use in another. With site built construction, a general contractor would send any overage to the recycle bin or to the dump. A 2. 00. 7 report published by WRAP supports the fact that off site manufacturing processes can help the construction industry reduce waste. Offsite manufacturing already offers the construction industry benefits in terms of time and cost predictability, health and safety, and skills. However, this work shows there is the potential to make a significant difference to the amount of waste the industry produces. The WRAP report shows up to a 9. A recent Environmental Protection Agency EPA report states that the industry average of C D waste for non residential projects is approximately 4. A LEED Gold certified modular project by NRB Inc. Find more information on the project here. WRAP has developed an excellent resource, Designing out Waste A design team guide for buildings to help owners and contractors. The report names key principles that design teams can use during the design process to reduce waste, one of which is design for off site fabrication. The report states that modular construction helps the industry reduce waste by improving the workmanship quality and reducing on site errors and re work, which themselves cause considerable on site waste, delay and disruption. In addition, other benefits of off site construction are reduced construction related transport movements, improved health and safety on site through avoidance of accidents, and reduced construction timescales and improved programs. The report also names design for reuse and deconstruction as another key design principle to use to reduce waste. The modular construction industry has for many years been practitioners of flexible design and reuse. Whole buildings can be reused by reversing the process in which the building was installed. The building can come apart in pieces in the same way they were created. The complete reuse of the buildings is a much more sustainable concept than abandoning or demolishing the building. Following is a case study where deconstruction and complete reuse were applied to a modular building. Marriott Grande Lakes Sales Center. The sales center was initially manufactured in 2. Myrtle Beach, SC. After 6 years of use, the building was disassembled including a complete site built roof portico element, and sent to storage. In 2. 00. 9, a new development in Florida required an upgrade sales center. It was determined that 6 of the original 1. The renovated building features 1. This architectural detail conceals the roof mount HVAC units and extends the building height to 1. The exterior wall finish is synthetic stucco with corbel elements below soffits, architectural banding, leader pipes, columns and indirect architectural lighting. Find more information here. Summary. Site built construction focuses on recovery, reuse, recycling or diversion of waste post construction, rather than reducing waste on the front end, through better management, procurement, and construction practices. Designing out waste at the earliest stages of the construction process, however, offers the greatest opportunities for waste minimization. Design for renovated reuse and deconstruction also has an important role in streamlining the construction process to reduce waste. Once effective waste reduction measures are in place, it is then appropriate to consider how to reuse, recycle, or dispose of the remaining waste. Modular construction, combined with the use of BIM, provides an effective technique to reduce overall waste on a project, providing a more environmentally sustainable building solution and creating a healthier and safer environment.
