Components produced at close supervision .so quality is good. Disadvantages Of Prefabricated Construction . Time spend in bad weather or hazardous environments at the construction site is minimized. The prefabrication of homes has long been a dream of many architects, but it has been the mining industry that has really been responsible for the development of the concept into a fully viable industry. This usually means that the owner will be required to pay the fabricator in cash until the house is delivered. In most modern industries automation has played a big part in reducing the total number of working hours with the intent of keeping a lid on prices, but the housing industry is intrinsically labour-intensive, and on a building site the usefulness of automation is limited. The time advantages come from many areas, but include having much better equipment on hand and in close proximity to the building site, the ability to build the house in a central industrial location where suppliers are in close proximity, improved worksite lighting and, in the case of manufacturers who have internal workspaces, there are no weather delays. As the price of labour in Australia has steadily increased, the cost of building quality homes has become increasingly unaffordable. PRO: There may also be advantages in the approval process as no building permit is necessary until the house is brought to the site. Disadvantages of Prefabrication. This Modern technique haven’t penetrated into our roots. It also allows us to set up standardized checks all the way through assembly allowing us to build better, higher quality buildings. CON: Prefabricated buildings are limited in size by requirements for permissible road widths and heights. Installation of building finishes can be done immediately. Furthermore, transportation and logistics of large sections may also prove burdensome for companies. Prefabrication is the practice of assembling components of a structure in a factory or other manufacturing site, and transporting complete assemblies or sub-assemblies to the construction site where the structure is to be located. PRO: The controlled environment makes the building process more predictable which should limit the risks of variations. The agreed design needs to be finalised earlier in the construction process and adapting the design may not be possible; 3. not always … AIMS OF PREFABRICATION CONSTRUCTION Prefabrication is used to effect economy in costcost. These methods reduce construction time at the site, facilitate better quality control and reduce labour component which involves in the site. Employment of organized labor and their service benefits cause a huge establishment. To identify the current requirements for energy efficiency in new build houses. The unique selling point of Prefabrication and Modular Building Construction, which is reportedly predicted by various reliable sources to grow at CAGR of 6.50% between 2015 and 2020 totaling USD 209 billion by the end of the decade, is minimizing cost and maximizing ROI. PRO: Because prefabrication occurs in a controlled environment it is easier to estimate the actual cost of construction. They can be lifted off the truck using simple hydraulic jacks, but if the site is difficult they may need to be craned into position. Modular construction targets all budgets and price points, creating an affordable option. These allowances will be incorporated into their contract price. Increased Risks ; First, there can a lot of risks associated with this technique in comparison to the traditional construction methods. The paper consist of advantages and disadvantages of prefabrication construction, and from this we got to know that prefabrication is the future. As the mining construction boom is slowing down, a number of prefabrication builders are now looking towards the residential market to fill their orders.
