On prefabrication implementation for different project types and procurement methods in Hong Kong Vivian W. Y. Tam 1*, C. M. Tam2 and William C. Y. Ng3 Abstract ... “Economics of scale” ranked as 8th in the survey with a RII value of about 0.73 and highlighted as “Medium” important level in reducing construction waste. Once the final project is obtained and approved, is it possible to start with the building phase. An innovative idea is to allow companies to mass-produce their own prefabricated houses. Investment in construction accounts for nearly 11% of India’s GDP (Job et.al 2013). See our User Agreement and Privacy Policy. Under these circumstances, a BIM delivery and assembly model could be a interesting solution to prevent problems. work closely in order to adapt the prefabrication process to a whole building. to pay attention to the verification process, leading to extra labor and time costs. In this way, SWOT analysis collects key information in two different groups: Identification of SWOT matrix is useful because it helps to inform later phases if the objective is achievable. The obvious and most important benefit of our new Advanced Manufacturing facility’s safety features is that employees go home safe at night. The Prefabricated Process is a high performance method, that highly increases the efficiency in building production. Prefabrication, an ever-growing idea throughout the era of modern architecture, is a vital tool for the development of housing. SWOT analysys approach, is the most crucial tool adopted for the strategic analyses of MPHP. :brick is a small unit precast and used in building. 2. When the all process is completed, the finished product, will be an whole house, which has been assembled with the same production process that is used today in the automotive industry. prefabrication must be optimised. UIN: 668929303 Prefabrication entails walls, foundation stones, and other units of construction, which are manufactured in bulk, transported to the location of the building, and simply ‘fixed’ on site which can be used to build modular and affordable housing in India.

Prefabricated system products from factories, meet several well-known problems, when they are applied in the construction industry. In case that the goal is not achievable, decision makers must select another goal and repeat all the process again. This tool helps to specify the internal and external factors, that are favorable and unfavorable to achieve all the project targets. The Prefabrication and Modularization report provides data and analysis on the impact of this trend on key industry productivity metrics, such as project schedules, costs, safety, quality, and eliminating waste. Users of a SWOT matrix, need to create useful information, to make the tool able to explains their possibilities. The report shows that BIM and prefabrication/modular construction improve both worksite productivity and overall project ROI. In the research for a specific and real application, would be interesting to apply the tool described in this article, to a company. The tool is recognized extensively and constitutes an important means for learning about The focus of this chapter is to provide the insight, that modular product architectures bring into the building industry. The second step, is research through questions, in order to investigate the SWOT of prefabrication housing production. Careful handling of Prefabricated components such as concrete panels or steel and glass panels is required. Starting from this concept, this article explains how to apply to the industry of prefabricated houses, the production managing system and the SWOT tool, used in automated factories. 2005], https://doi.org/10.1016/j.habitatint.2016.07.002, http://wiki.doing-projects.org/index.php?title=SWOT_analysis_for_Prefabrication_Housing_Production&oldid=70245. Construction industry is largest economic expenditure in India. Prefabrication has widely been regarded as a modern way of construction that reduces the generated construction wastes (Lu and Yuan, 2013, Zhang et al., 2011, Aye et al., 2012), decreases noise, dust, and operation time/cost (Jaillon and Poon, 2009, Li et al., 2011, Pan and AG Gibb, 2007), and increases construction quality, and health/safety standards (Pan and AG Gibb, 2012). However, the critical success factors (CSFs) remain unrevealed. “Safety and quality go hand in hand,” says Tracy Haus, Safety Director for Baker Group. Scandybig has over 40 years of product development, their expertise enables to design solutions that match the individual customer's wishes and requirements for a building project. Research Paper on Trickle-Down Economics of Prefabrication Safety. Mainly questions are related with information on the benefits that result from MPHP development, including The origins and forms of prefabrication and industrialised building are examined and the economics of these processes critically investigated. SWOT is also described as a management tool, to develop strategic analysis. Prefabrication is not new, yet our findings show that the industry is still struggling to adapt this manufacturing technique at a broad level. In the interview discussion, a construction organization noted that prefabrication … There are already numerous prefabricated projects on the market, carried out by important industries in the sector. Even thought customers can customize their home according to their needs, companies will not need to adapt their tools for each building, so it could use every time the same production line. Abstract- Prefabrication has been widely regarded as a sustainable construction method in terms of its impact on environmental protection. This methodology is atypical in the construction industry, but it could rise various improvements. Another point in support of this is that one is not dependent upon weather conditions or organisational factors on the construction site. They therefore attempt to create a product which is appropriate in configuration, use and maintenance. “When employees avoid injury and stay in good health, we also maintain the manpower to accommodate our clients’ … The limited space results in more time for vertical transportation of precast units from the ground level to the designated floors. 7)By ElzbietaRadziszewska-Zielina, Monika Glen.,Studies of the Prefabricated Housing Construction Market in Poland An Poland to compare the economic benefits of traditional construction methods to prefabricated building systems indicated that the latter provided site labour savings of up to 70% while its incurred total construction where savings of close to 50% are achieved through the use of whole … [7] R.E. THIS CHAPTER EXPLORES the effect of site and market conditions on building costs and the way in which they account for variations in the price of similar type buildings erected in different locations. This page was last modified on 3 March 2019, at 12:32. Downloadable! v Small Prefabrication : The first 3 types are mainly classified according to their degree of precast . The various experiences developed over the years show that, It is a process where the different design teams (for example: structural engineers, architect, building services engineers, etc.) The word SWOT is an acronym for the four parameters which the matrix examines: Using the SWOT analysis tool, is it possible to identify all the internal and external factors, in a business project. It is found that prefabrication in construction is an economic and sustainable practice that could cater the needs of providing affordable housing in the current … Companies, are researching different methods to further develop the concept of prefabrication. Prefabrication This ongoing effort suggests that supplying system products to the construction industry and implementing them in building construction projects is not a straightforward matter; it may be associated with considerable managerial and practical challenges. These documents, are collected from two different sources: market investigations and reports by consulting stakeholders involved in building production. With the advance of technology and the expansion of knowledge, many companies have finalized to the conclusion that the process of houses prefabrication is more efficient than the on-site construction. This is a specific result on SWOTs study[7] on prefabricated buildings. Finally, Construction workers on the sites are often preoccupied with their responsibilities and knowledge. The company's primary business area is construction of housing, offices, and institutions with prefabricated element, for professional private and public customers. Prefabricated construction has long been adopted in Australia, USA and northern Europe. Despite the fact that researches and new instruments have been applied in this emerging industry, most of them need to be further improved. Along with industrial manufacturing and economic benefits come labor challenges. Manual handling of ordering information is extremely difficult. This chapter aims to determine the sustainability of prefabricated buildings by studying the economic, environmental and social impact of the methods of prefabrication used in their construction. These companies are responsible for providing the customer with a complete home, built according to needs and requests. During the process of prefabricated home, the design is done in collaboration between different partners, who have to develop their products using factory prefabrication methods. As a consequence, the price of rent has risen considerably, creating a situation in which citizens cannot afford an adequate accommodation. Examples of system products are integrated façade solutions, garrets, prefabricated kitchens, bathrooms and multi functional ceiling solutions. Verification of the components is also inefficient because of the extensive use of paper or paint labels. Industrialization can find expression in among other things the factory-like production of system products to be implemented in buildings. In order to comprehensively investigate economic benefits of implementing prefabricated construction techniques, this research establishes a framework for evaluating multidimensional economic benefits in terms of three aspects, namely, resource-use efficiencies, project progress, and incentive policies. To me, the critical issues concern the impact of prefabrication on employment and the skills needed in employment in relation to the economy of the country. Elements using in that construction for eg. This is a total new concept in the building design. As a relatively recent phenomenon, it is not clear whether the construction industry only presents conditions propitious for implementation of prefabricated parts, or if there are also conflicting factors complicating the business of supplying system products. That the degree of precast element is very low. Despite the focus of workers, accuracy of the verification process is not guaranteed because sometimes paper-based documents are unclear. Ankit Singhai Time spend in bad weather or hazardous environments at the construction site is minimized. The allure of prefabrication lies in the factory setting. Danish market uses the system product, which is a multi-technological complex part of a building, developed as a completed modular and variable product. 06.08.2018. These products are managed by a team of employees based in the Danish headquarter, who manage the administration, product and project portfolio and sale, and sales agents abroad take care of sale to foreign markets. Disadvantages of Prefabrication : 1. The findings revealed that environmental, economic and social benefits of using prefabrication were significant when compared to conventional construction methods.

The topic of modularity as a strategic and practical tool, related with the SWOT analysis, is difficult to implement. One of the most efficient methods, is based on prefabrication of building parts, but imagining them as small parts, which would later form a larger element. It is useful, especially for the strategic planning process. This page has been accessed 10,616 times. First, the corresponding models are proposed after determining the economic composition in terms of resource-savings, shortening of construction periods, and latest policy subsidies. Ideally, technical drawings of the construction components (e.g., slabs, partitioning walls, staircases, etc.) The root of the economic problem is the fact that the majority of the households do not have the confidence needed to construct prefab houses. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. “The issue of industrializing the construction market, through use of prefabricated system products, is closely related to that of modular product architectures, understood as initiatives to break down products or processes into smaller, interchangeable units as a means of achieving efficiency without ignoring customers’ varying needs” (Baldwin & Clark 1997; Sanchez 2004). If we want architecture to become as economic and efficient as possible (as is expected in the modern age,) then prefabrication needs to be widely accepted and incorporated throughout the entire process that architecture foregoes. Therefore, rational strategies to manage CW are equally necessary for both developed and developing economies [1].
