economics of prefabrication

A Comparative Evaluation of the Environmental Impact of Prefabrication versus Conventional Construction in UAE’s Construction Industry مييقت راثلأا ةيئيبلا ايجولونكتل عينصتلا قبسملا ةنراقم قرطب ءاشنلإا The report shows that BIM and prefabrication/modular construction improve both worksite productivity and overall project ROI. Prefabrication The findings revealed that environmental, economic and social benefits of using prefabrication were significant when compared to conventional construction methods. Receiving orders and changes from the clients would cause the production to become full of errors. The advantages of modularity include the achievement of scale economies while meeting various requests, a reduced need of managerial coordination, facilitation of innovation and development to meet changing market conditions as well as clarification of organizational knowledge. Companies, are researching different methods to further develop the concept of prefabrication. Clipping is a handy way to collect important slides you want to go back to later.

The design aspects are developed to raise quality and performance as possible. :brick is a small unit precast and used in building. This … The topic of modularity as a strategic and practical tool, related with the SWOT analysis, is difficult to implement. SWOT analysys approach, is the most crucial tool adopted for the strategic analyses of MPHP. [2]. 2. 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. 2005: 20; Pine et al. This trend has led researchers to explore the relations between modularity and a variety of managerial concerns [11] such as organizational knowledge, coordination , supply chains and the ability to develop or alter product components [12] and architectures. Today, after 30 years, sufficient knowledge is achieved in this field, in fact, precast elements are adopted for every part of the building including: parapets, precast facades, partition walls, semi-precast slabs,staircases, kitchens and precast bathrooms. Prefabricated construction has long been adopted in Australia, USA and northern Europe. This method create a double advantage for both the customer and the company. “Safety and quality go hand in hand,” says Tracy Haus, Safety Director for Baker Group. [6] Langdon and Everest, “Cost Model: Offsite Manufacture”, 2004. SAFETY : Almost all owners agree that overall project safety is improved through the use of prefabrication and modularization. Prefabrication comprises of a wide range of components, from manufacturing of windows, staircase, roof tops, trusses, to manufacturing of complete building units. 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 … Another significant economic impact on the buildings cost is generated by the transport of materials and the mechanical vehicles, needed in the construction process. The allure of prefabrication lies in the factory setting. 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). These products have a certain appeal because they employ modular architectures which enable suppliers to achieve production wise advantages while also offering customers some variety and customization through individual configuration of the elements forming the products. Each of these individual parts must be designed and built in the factory. 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.) SWOT analysis enables the identification of the main problem [6], confronting the construction industry which uses prefabrication technologies and contributing to the formation of a better understanding of both the internal and external situation of MPHP practice. prefabrication policies are two efficient strategies for reducing CW at the design stage. "The system product is developed for mass customization and it is developed with a room for variation within which it can be configured and individualized for each construction work." The prefab industry is the backbone for the development of new ideas in construction business of any country. Medium Prefabrication : Suppose the roofing systems and horizontal members are provided with pretested elements those … Prefabrication is a manufacture and preassembly of components, elements or modules before installation into their final location. Furthermore, the Prefabricated Housing Process is explained, with all the innovations and benefits, which this production method has brought into the estate market. v Small Prefabrication : The first 3 types are mainly classified according to their degree of precast . This implies that a wider use of prefabrication techniques could contribute to sustainable construction in a dense urban environment like Hong Kong. In contemplating various initiatives to develop the industry’s practices, increased industrialization is currently receiving considerable attention throw efficiency to the potential benefit of both customers and the stakeholders carrying out construction work. SWOT analysis is a strategic planning method [1], to assist companies identify advantages and disadvantages related to business aspects or project planning. However, the industry still has a long way to go to increase productivity and overcome project inefficiencies using prefabrication. Prefabrication This page has been accessed 10,616 times. Also, identified the hindrances in its application, and possible solution. Furthermore, architectural variety and innovation, always needs to be defined because “standardization is a key concept in modularization“ [13] . In the research for a specific and real application, would be interesting to apply the tool described in this article, to a company. Construction sites are often restricted within limited spaces for storing large and heavy components. 1. This is a hard concept, both to understand and to improve, because is not common in the building industry. Modular homes have many advantages including: Using the SWOT analysis on prefabrication housing production, is not an easy goal to achieve. The Prefabrication Process increase in efficiency, both in economic and temporal terms. By removing construction processes and time from the site and relocating them to a centralized facility, efficiency, and precision can be heightened, reuse of material can be optimized, weather is controlled, and skilled laborers can more easily be coordinated. Building plans are drafted using 8-foot ceilings, and floor plans are described in multiples of four. The manpower cost is higher, because it must be highly specialized, and it has to adapt its knowledge depending on the site and the project. 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. Prefabricated system products from factories, meet several well-known problems, when they are applied in the construction industry.

In the American building industry, for example, the 4 × 8-foot panel is a standard unit. 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. Almost every metropolitan city in the world, has housing problems, related with the mass concentration of people in small areas. In order the costs to be competitive the degree of prefabrication must be increased. Furthermore their ideas could reflect problems from a project-level, rather than from a general perspective. 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. components that are... 3. [7] R.E. This is a specific result on SWOTs study[7] on prefabricated buildings. 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. Morkel 2001; Staudenmayer et al. This paper aims to examine the CSFs for the planning and control of PHP projects. Research on modularity also includes a continuous investigation of the further potentials and limits associated with modular product architectures. Despite the fact that researches and new instruments have been applied in this emerging industry, most of them need to be further improved. This chapter explains how to apply the SWOT analysis tool[1] to the Management of Prefabrication Housing Production (MPHP)[5]. prefabrication/modularization offers a less costly alternative. Using the prefabrication process, governments could have the opportunity to supply sufficient dwellings and solve overpopulation problems. In the interview discussion, a construction organization noted that prefabrication … 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. The decomposition of products and the standardization of components’[4] interfaces is what theoretically enables modularity to ensure such individual solutions .
