Environmental management in construction - Myassignmenthelp.Com

Question: Discuss about the Environmental management in construction. Answer: Introduction This report designs a waste management system for the construction site defined in the assessment brief provided. The waste management system is to be designed for a large construction site with space in the rear and front side but accessible by truck from the front side only. The type and amount of each type of waste generated from the site is considered when designing the system. This helps in deciding on the appropriate layout and location of waste management components in the construction site. The system encourages re-use of materials where possible, avoiding waste in possible cases as well as recycling. Materials that cannot be re-used or recycled can be dumped in a responsible and environmental friendly manner. Job-site waste reduction plan One of the important steps in waste management planning is ensuring waste reduction. The following are the methods: Purchasing of materials in bulk is an important step towards reducing waste materials. Use of returnable materials and packaging materials also helps in waste reduction. The non-returnable containers can be given away to people who have more use for the materials.

Another method is using scrap in lieu of cutting materials. Subcontractors should be contracted to come and collect the waste materials for recycling. To reduce waste, it is important to establish return or buy back clauses with suppliers. Serviceable materials can be sold to architectural salvage or used in retail outlets Another method of reducing waste materials at the construction site is contracting CD recycling firm. The firm can pick and transport debris and other waste materials that they can find useful for recycling or re-using. Recycling,re-use and disposal of the waste materials Excavation material-This is the material generated from digging the earths surface to construct the basement of the building and to lay the foundation of the building. The materials include soil, sand and rocks from the earths surface.4Excavation materials consists of a very large proportion of the materials from a construction site. The construction site is estimated to generate an average of 140 million m3.. Of the excavation material that is generated from the construction site, 30% of the material is re-used. This means that 42million m3 of the material is re-used. Daven, James I., and Robert N. Klein. 2008. Progress in waste management research. New York: Nova Science Publishers. Haggar, Salah el-. 2007. Sustainable industrial design and waste management: cradle-to-cradle for sustainable development. Amsterdam: Elsevier Academic Press. https://public.eblib.com/choice/publicfullrecord.aspx?p=307125. More than 80million cubic meters of construction material is disposed in land fills. Since the excavation material is not an hazard to the environment,it can be used to fill land mines. Concrete materials from the construction site also represent a large proposition of waste from the construction site. The concrete material is mainly from demolition. 5The demolition of the current structures that exist in the construction site will produce approximately 20 million cubic meters of materials. There are also other materials that will be generated from the concrete debris at the site. 6Waste will be minimized by ensuring that the structure and design of the building is strictly followed to avoid unnecessary demolitions which will increase the construction waste from the site. Concrete is crushed and metals that are embedded are removed for recycling. The concrete waste materials can be re-used when constructing the pathways around the building. The construction waste can also be used to construct the road that leads to the building. The concrete materials can be disposed off to fill landmines and to repair rural all-weather roads.

Steel waste materials are generated from the steel metals that are used in laying the foundation of the construction site and part of roofing of the building. 7The parts that are cut in order to meet the size and shape requirements form the waste materials generated. Steel is separated from the other metal waste at the construction site using heavy machinery. The steel can be re used by taking it back to the factory where it can recycled. Card board and paper-This consist about 3% of the construction waste materials. This is generated from ceilings and partitioning of rooms.8 Plastics are down-cycled and produced into wide variety of products. Cardboard and paper are transported to paper and cardboard mills for recycling. Wood-It represents 30% of all waste generated. Wood waste is generated from ceiling construction and furniture. Wood waste is recycled into biomass and can also be used to used to make cardboard. Yang, Jianming, and Agnes Zhang. 2017.

Critical management measures contributing to construction waste management: evidence from construction projects in China. Electrical waste materials consists of 1% of the total waste materials from the construction site. 9The waste can be reduced can be minimized by ensuring proper accurate measurements of electrical wires and other electrical installations required for the project. Electrical waste can be separated from the other waste materials by sorting out the materials. Copper and aluminum wires can be recycled to produce similar products. Lauritzen, Erik K. 2017.

Facility design The site will be designed in such a way that waste disposal and sorting out will be very easy.10 The design also aims at making transportation of waste materials from the construction site easy and effective. In addition to this, the issue of volume of waste produced and the available space is also considered when designing the site. Conclusion The report identifies and defines waste management system that is appropriate for the construction site. The system is developed to accommodate different types of wastes generated from the construction. Some of the types of waste materials that are managed in this report include; excavation materials, plastic waste, wood, card board and paper, concrete materials as well as electrical waste materials. The paper identifies methods that can be used to minimize different types of waste materials from construction. This helps in optimization in resource use hence reducing costs and also in minimizing environmental degradation from waste materials. The paper also estimates the volume of waste materials for each category of construction waste and designs the location of each waste management site. In addition to this, the methods of recycling re-use and disposal of the construction waste. The paper contains a graphical representation of the issues addressed in the CME 107.
