Elements using in that construction for eg. The process required the set up of a construction site, which costs time and a large amount of money. Industrialization can find expression in among other things the factory-like production of system products to be implemented in buildings. Prefabrication for improving Sustainability and Economics of Civil Engineering Projects 1. Smith, “History of … With the rapid emergence of innovative technologies, such as augmented reality, 3-D scanning and printing, XD-BIM, drones, etc., it is easy to get caught up in all the technology buzz and forget about what it really takes to innovate and change. Despite the focus of workers, accuracy of the verification process is not guaranteed because sometimes paper-based documents are unclear. 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. The system is developed in a separate product development process based on the principles of integrated product "development for life cycle", which means preparation of its marketing, delivery process and servicing. Using the prefabrication process, governments could have the opportunity to supply sufficient dwellings and solve overpopulation problems. [7] R.E. v Small Prefabrication : The first 3 types are mainly classified according to their degree of precast . This tool helps to specify the internal and external factors, that are favorable and unfavorable to achieve all the project targets. :brick is a small unit precast and used in building. Modular homes have many advantages including: Using the SWOT analysis on prefabrication housing production, is not an easy goal to achieve. Prefabrication and modular construction are processes that have been used by generations of construction … 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. Ankit Singhai Research on modularity also includes a continuous investigation of the further potentials and limits associated with modular product architectures. Prefabrication is a technology that can reduce the material consumption during the construction process. SWOT analysis is a strategic planning method [1], to assist companies identify advantages and disadvantages related to business aspects or project planning. Now customize the name of a clipboard to store your clips. The organization has a long history of manufacturing solutions for other purposes than construction work. The origins and forms of prefabrication and industrialised building are examined and the economics of these processes critically investigated. should be generated directly from the BIM model to the manufacturers who will produce them accordingly. This is a total new concept in the building design. 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. Medium Prefabrication : Suppose the roofing systems and horizontal members are provided with pretested elements those … The … 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. “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). Theoretical advantages [9] of pursuing modular product architectures have already been elaborated extensively, and they have been documented [10] in specific product contexts, particularly in the area of personal computers . Another point in support of this is that one is not dependent upon weather conditions or organisational factors on the construction site. 1. 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. SAFETY : Almost all owners agree that overall project safety is improved through the use of prefabrication and modularization. In the current era of globalization ... Prefabrication is a manufacture and preassembly of components, elements or modules before installation into their final location. In the research for a specific and real application, would be interesting to apply the tool described in this article, to a company. This method create a double advantage for both the customer and the company. 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. The design aspects are developed to raise quality and performance as possible. work closely in order to adapt the prefabrication process to a whole building. The term 'prefabrication' describes assemblies that are manufactured under factory conditions and then transported to construction sites for incorporation into building or civil engineering works. The limited space results in more time for vertical transportation of precast units from the ground level to the designated floors. Time spend in bad weather or hazardous environments at the construction site is minimized. 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. Examples of system products are integrated façade solutions, garrets, prefabricated kitchens, bathrooms and multi functional ceiling solutions. 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. 2005: 20; Pine et al. The external conditions are related to the threats and opportunities, whereas the internal conditions refer to the weaknesses and strengths. 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. Along with industrial manufacturing and economic benefits come labor challenges. Thus, it is regarded as a technology that be of assistance in the pursuit of sustainable development in the construction industry. After years of developments, the results of the company were the introduction of various concept. prefabrication/modularization offers a less costly alternative. 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. In order the costs to be competitive the degree of prefabrication must be increased. Integrated product development means that developers make decisions which have consequences in the rest of the product’s life cycle. 25, No. By empirically … 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. The obvious and most important benefit of our new Advanced Manufacturing facility’s safety features is that employees go home safe at night. Research Paper on Prefabrication prefabrication policies are two efficient strategies for reducing CW at the design stage. As technology made way for mass production and assembly line manufacturing methods in the early part of the 20th century in the U.S., developing countries are using the same process to produce goods abroad today. Companies can save large amounts of money by applying a mass production process, avoiding changing in the production methods of every single project. Modular construction targets all budgets and price points, creating an affordable option. 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, an ever-growing idea throughout the era of modern architecture, is a vital tool for the development of housing. The tool is recognized extensively and constitutes an important means for learning about Once the final project is obtained and approved, is it possible to start with the building phase. Current practice may also cause safety issues. SWOT analysys approach, is the most crucial tool adopted for the strategic analyses of MPHP.  A construction industry term used to describe a building or structural From a practical application of the SWOT analysis, Danish companies would receive helpful information, because they could easily evaluate its elements within the SWOT matrix. The Prefabrication Process increase in efficiency, both in economic and temporal terms. There are already numerous prefabricated projects on the market, carried out by important industries in the sector. It is useful, especially for the strategic planning process. Practical advantages of using prefabrication are mainly related with economic benefits. "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." This chapter explains how to apply the SWOT analysis tool[1] to the Management of Prefabrication Housing Production (MPHP)[5]. Ideally, technical drawings of the construction components (e.g., slabs, partitioning walls, staircases, etc.) The findings revealed that environmental, economic and social benefits of using prefabrication were significant when compared to conventional construction methods. ... Construction Management and Economics, Vol. Owners are able to shift some of the work to an off-site location and take advantage of cheaper labor costs. Similar to electronics companies, a manufacturer commonly supplies various prefabrication components to different clients and their construction sites. Therefore, for each individual project, the company will have to adapt its production each time according to the guidelines received. 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. Mainly questions are related with information on the benefits that result from MPHP development, including This technique is applied through the use of a SWOT matrix which explains strengths, weaknesses, opportunities and threats of the project. 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. 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. Prefabrication is not new, yet our findings show that the industry is still struggling to adapt this manufacturing technique at a broad level. Prefabrication is a manufacture and preassembly of components, elements or modules before installation into their final location. Prefabrication Despite the various complications that can arise, producing prefabricated houses with the same industrial process used in the automotive industry, could be an example of innovative vision. 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. “Safety and quality go hand in hand,” says Tracy Haus, Safety Director for Baker Group. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. This methodology is atypical in the construction industry, but it could rise various improvements. The Prefabricated Process is a high performance method, that highly increases the efficiency in building production. 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. [2]. In the interview discussion, a construction organization noted that prefabrication … Looks like you’ve clipped this slide to already. In prefabricated constructions, a balance between systematization and standardization must be found. a situation and designing future procedures that can be considered necessary to enable strategic thinking. If you continue browsing the site, you agree to the use of cookies on this website. Furthermore, prefabricated houses are affected by other practical disadvantage [15] , including: SWOT analysis for Prefabrication Housing Production, Tool application - Danish Construction industry, Strenghts: wide experience in prefabricated construction, Weaknesses: problems between design and prefabrication stages, Threats: inefficient installation management, Advantages of the House Prefabrication Process, [Osita, Christian; Onyebuchi, Idoko; Justina, Nzekwe (31 January 2014)]Organization's stability and productivity: the role of SWOT analysis, [Mikkelsen et al. 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 From this concepts a number of products were developed. 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. You can change your ad preferences anytime. 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. These documents, are collected from two different sources: market investigations and reports by consulting stakeholders involved in building production. Downloadable! 06.08.2018. However, the industry still has a long way to go to increase productivity and overcome project inefficiencies using prefabrication. Scandibyg develops a product program which matches different customers’ different needs and doing it in a cost-effective way by ensuring some common features in construction, production and installation. 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. 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. Results coming from opinions of other stakeholders, help the understanding of practical construction problems in the precast housing production process. Building plans are drafted using 8-foot ceilings, and floor plans are described in multiples of four. The first step is to confront the current housing challenges with a detailed analysis of collected documents. Finally, Construction workers on the sites are often preoccupied with their responsibilities and knowledge. First, the corresponding models are proposed after determining the economic composition in terms of resource-savings, shortening of construction periods, and latest policy subsidies. These companies are responsible for providing the customer with a complete home, built according to needs and requests. An environment, where could be interesting to apply the SWOT matrix tool, is the Danish market of prefabricated buildings. 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 construction process starts with a project, which is developed by professionals and requires a certain amount of time to be completed. Third, based on the identified SWOTs, suggestions to improve the prefabrication housing production are proposed in accordance with the principle of transforming weaknesses to strengths, and minimizing threats. The results, from the research, are obtained from a series of structured interviews with major stakeholders, manager from precast manufactures, logistic companies and engineers. 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. 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. Verification of the components is also inefficient because of the extensive use of paper or paint labels. Therefore, site management is often the critical path for the success or failure of a construction project.
