Comparison Of Mivan Formwork System With Conventional System Construction Essay

Comparison Of Mivan Formwork dust With pompous System eddy EssayIn recent beats payable to globoseization, the bodily structure sedulousness has started foc exploitation on new innovative slip demeanor of working. The bend industry has started adopting new technologies and approaches in order to increase the overall efficiency of the pick up. This report is about the new methods of bend and new materials that behind be hired to improve the overall social organization process.The startle half(prenominal) of the report is on the atomic number 13 formwork arrangings (Mivan System) which is used for mass lodging saying. This formation of aluminium forms is fast, long, cost in force(p) and to a fault produces forest work which takes marginal precaution. The second half of the report is on third estate chapiters a smart material which is a repla cementum for tralatitious ceilings. Today in this renew globe where global heat is the major concern for all countries, dark- unfledged ceilings sight be one of the innovative ways to reduce the zipper consumption which ultimately helps in reduction the CO2 emissions.1. IntroductionThe bend industry is one of the biggest industries in the whole world. The contribution of this industry towards the global GDP is enormous. In recent divisions receivable to globalization and progress in technologies there has been a tremendous development in the twirl industry. However despite of the boom in locution activities the scenario on the caparison forepart remains far from satisfactory. In the countries like India and China the property on the housing front is even worst. collectable to ever increase population in these countries there is an over maturement consider for housing. today keeping in view the gigantic task of providing affordable shelter to masses, adoption of modern and cost effective technology assumes great signifi tailce.The modern methods of social structure argon broad range of processes and products that aims to improve business efficiency, character reference, customer satisfaction, environmental performance, sustainability and the predictability of sales talk timescales (Baker 33 Cross industry Group, 2006).Today there is a suppuration realization that the speed of twisting take ups to be accustomed greater importance especially for self-aggrandising housing projects. For undertaking mass housing works, it is necessary to have innovative technologies which atomic number 18 capable of fast swan construction and atomic number 18 able to deliver good quality and durable structure in cost effective manner (Anon, 2010). Several schemas are adopted all over the world but Mivan system has be to be reasonably economical and capable of fast rate construction of mass housing. In this system debates and slabs are draw off simultaneously at situate by use of specially designed, elementary to handle f st rainfallwateringylike burd ening aluminium forms (Anon, 2010). The system is far more(prenominal) than faster than the handed-down beam and tug construction.However as per Sir John Egan report Rethinking Construction (1998), the commitment from major clients, from the construction industry itself and from the government is the scarce way forward to create and sustain the environment that is pauperismed for strong melioration in performance, efficiency and quality of the construction.The construction projects are getting more complex in nature overdue to growing human strive and the construction industry need to respond to the unique challenges presented in front in terms of time cost and quality. Also the industry testament need to respond to the major issues such as global melt and health and safety of the workers. We as a member of the construction industry will need to overcome these issues by using modern methods of construction (like Mivan System) and smart materials (like chiliad roofs) fo r carrying out projects.The main objective of this report is to explore modern methods of construction and smart materials and in any case to evaluate their impact on the construction process in terms of time, cost and quality. In the first half of the report, the use of Mivan formwork system during the construction process is discussed eon in the second half idea of using green roofs is discussed.2. Mivan formwork System (Aluminium formwork system)Mivan is fundamentally an aluminium formwork system developed by the Mivan Company Ltd from Malaysia in the year 1990. The technology has been used commodiously in new(prenominal) countries such as Europe, Gulf Countries, Asia and all former(a) parts of the world. MIVAN technology is suitable for constructing banging number of houses within short time using room size forms. In this system of formwork construction, discard in situ cover wall and story slabs are casted monolithically in one continuous pour. Large room surface f orms for walls and ditchs slabs are erected at aim as shown in the common fig tree1 below. These forms are strong, easy to handle and are fabricated with accuracy. They can be used repetitively around 250 times.The frames for windows and door as well as ducts for serv grumps are placed in the form before concreting as shown in the get a line 1. Stair berth races, faade panels, chajjas and jails etc. and other pre-fabricated items are also interconnected into the structure as shown in figure 1 and 2. This proves to be a major advantage as compared to other modern construction techniques. phone number 1 A set of Mivan formwork underframe 2 Staircase flight formwork2.1 Comparison of Mivan formwork system with Conventional ConstructionThe table below shows the relative analogy between the Mivan form work system and the stodgy system. The comparison is make on the factors such as speed of construction, quality of construction, aesthetics, outside finishes and maintenance.Factor sConventional ConstructionMivan formwork systemSpeed of constructionThe speed of construction is much slower due to step by step closure of different stages of the activities such as erection of formwork, concreting and deshuttering and thereafter plastering and other finishing activities.In this system the wall and the floors are casted simultaneously in one continuous operation and also the finishing work can be started immediately, so the speed of the construction is much faster.Quality collectible to conventional method of construction normal quality is prevailedSuperior quality is obtained due to in-situ casting of whole structure and transverse walls through in continuous operationAestheticsIn the case of conventional construction the partition walls are do up of bricks due to which the column and the beam show unsightly projections in room interiors.In case of Mivan system the partition wall and the ceiling elements are casted together due to which the interiors have neat and clean lines without unsightly projections in various corners. The wall and the ceilings also have a smooth even surface.External finishes altogether the external walls are made up of bricks, so it requires manual cement plastering which needs to be repainted frequently.All the external walls are made up of concrete and do non require manual cement plastering and also have smooth finishing, so this will need no frequent repainting.MaintenanceThe maintenance cost is too full(prenominal) school as it requires frequent improves of plasters of wall and ceilings, painting of outer and inner walls due to leakages.The maintenance cost is negligible as the walls and ceiling are made up of high quality concrete which do not require frequent repairs.Table 1 Comparison of Mivan Formwork System with Conventional construction2.2 Benefits of Mivan formwork SystemAccording to Mivan (Thailand) Limited the spare-time activity are the main benefits of using Mivan formwork system.2.2.1 Speed o f constructionThe structure is completed much faster than the traditional formwork as a large-scale amount of work can be completed in each daily work routine.thither is no need for brick laying and plastering as all walls can be formed at the same time.Finishing work such as window fixing, wall tiling and plumbing work can be installed immediately once the concrete is casted.2.2.2 Building strength and durabilityThe walls and the floor slabs are casted simultaneously so there are no spineless joints.The walls are made of reinforced concrete which provides much greater stability than columns with brick walls.The wall surfaces are made of concrete which do not blemish like plaster and maintains a smooth surface for much interminable time.2.2.3 Quality of finishing buildingThe formworks are manufactured precisely which allows the concrete to be cast to exact dimensions as designed.Services like pissing supply some waste pipes and electrical conduits, can be cast into the concre te where it is protected and not visible.2.2.4 Financing costFast project completion saves financing charges as the buildings can be transferred to the owners much previous than traditional methods.2.2.5 Efficiency and cost savingThere is no indispensableness of labours for building brick walls and plastering as major part of the structure is cast in concrete by small group of workers.The project can be completed in shorter time due to fast proceeds methods which save on internet site running, operating and financing cost.The formwork panels are light in weight and can be lifted manually, so there is no need of spending money for weighted cranes for lifting.Less skilled labours are demand on the site as all the finishing items are prefabricated.2.2.6 environmental benefitsThe formworks are made up of aluminium which can be reused and also can be recycled to make other products.2.3 Case studyThe following is a case study which justify that incorporating Mivan formwork system in the construction project is very beneficial to the project.2.3.1 eternity rise- DubaiAs per MFE formwork technology (2008), the eternity Tower in Dubai is a 73 storey residential tower with a dynamic twisting shape as shown in the figure 3 below. The tower is more than 300 meter in top and has been designed by Skidmore Owings Merrill who also designed the worlds tallest tower, Burj Khalifa which is 828 meters in height. The contract was awarded to Arabtec Construction. The morphological system for the tower is high strength with a reinforced concrete column superstructure that rotates with the twisting shape. In addition, each floor will concur a 1.08-degree twist to achieve the full 90-degree spiral.Figure 3 Infinity Tower (Source MFE formwork technology)The tower was constructed by using a light weight aluminium formwork system. A special twisting aluminium panels were made to obtain the precise design. The tower was constructed at a speed of 8 floors per month when the si te was in full flow, maintaining zero tolerance with regard to site safety. Now by referring to this case study, it is clear that the use of Mivan formwork system not only improves the quality and speed of construction but also maintains site safety.2.4 Limitations of Mivan formwork SystemThe following are the limitations of using Mivan formwork SystemModifications are not possible as all members are cast in RCC. conceal services become difficult due to small thickness of the components.The aluminium formworks are far more expensive than the conventional formwork.Heat of hydration is high due to shear walls.The finishing lines can be seen on concrete surfaces due to small sizes.It requires uniform planning as well as uniform elevations to be cost effective.The shrinkage cracks are likely to have the appearance _or_ semblance due to box type construction.The formwork can be cost effective only if it is used in symmetrical type of structure.3. green detonating devices thousand roof refers to a system of roof that uses plant life for roof covering instead of traditional covering materials (Green Roofs Today, 2010). Department of Trade and constancy (2004) defines the smart material as a material that senses its environment and responds. Green roofs provides constant temperature throughout the year due to high degree of withdrawal they provide, hence they can be termed as smart materials.Green roofing has become increasingly popular in the cities as it creates additional green spaces that bring some nature in concrete and steel jungle (Green Roofs Today, 2010). Green roofs are visually appealing and create an attractive credit line to concrete and steel as show in the figure 4-5 below.Figure-4 (Green Roofs) Figure-5 (Green Roofs)There are several components of green roofs which besides plants include a growing medium, a filter cloth, drainage, insulation and a waterproof membrane (Green Roofs Today, 2010). These components are shown in the figure 6. The con struction of rooftops and the selection of plants for roof covering work out on the factors such as size of the building and type of roof. Now for construction of green roof both flat and slopped roofs are suitable but for construction of large park like roof system only larger buildings are appropriate as registration of large plants and trees are too heavy for medium sized buildings.Figure 6 Components of Green Roofs (Source Green Roofs Today, 2010)Green roofs are mainly of triad types Intensive, Semi-Intensive and grand roofs, depending upon the selection of plants (Green Roofs Today, 2010). Intensive green roofs are those that accommodate large plants, trees, full lawns etc. This type of green roofing requires a significant depth of soil and also requires heavy maintenance. Semi Intensive green roofs are those that accommodate moderate size of plants and require less maintenance. Extensive green roofs is the most convenient of all types of green roof systems and involves roo f covering with a thin layer of growing medium and flora that requires minimal care and maintenance (Green Roofs Today, 2010).The factors which are taken into consideration while designing green roofs are orientation of roofs, preferred planting, level of maintenance and performance expected from the plant layer (Green roofs, 2006). As the intensive roofs harp of deep layer of growing medium, it needs special consideration at the time of designing as they require specific support from the building. Conversely, extensive green roofs require negligible structural support from the building, hence no special consideration is given at the time of designing them (The green roof centre, 2010).3.1 Benefits of Green Roofs SystemThe following are the benefits of Green Roof systemsPlants reduce the air taint by absorbing harmful gases including cytosine dioxide and releasing oxygen. Green roof system therefore reduces the air pollution and makes the air cleaner and healthier especially in urban areas where quality of air is a major problem.Plants tend to absorb the heat from the air and release it into the air when the temperature drops. Green roof system therefore helps in lowering the temperature of the urban areas. It also helps the building owners to reduce their cost for heating for heating and alter which is good for the environment too because most chill and heating systems are powered by energy that is obtained from non-renewable sources such as fossil fuels.Plants that cover the roofs can absorb up to 75% of the rain water. Therefore the green roofs system significantly reduces the amount of water that runs in to the sewage system. The plants also filter umteen pollutants in rainwater including heavy metals. The rainwater that is absorbed by the green roofs is then released into the air via abridgement (Green Roofs Today, 2010).Green roofs system offer a natural habitat to many local animal life including insects and birds that were virtually driven out from urban centres.Green roofs systems are extremely durable and can last up to 50 years. It also does not virtually require any repair like many other roofing systems.Green roofs combined with other green technology such as solar thermal collectors and solar photovoltaic panels can further reduce the costs for heating and cooling as well as help combat the global warming (Green Roofs Today, 2010).The figure below from the (Green Roofs Today, 2010) shows the main benefits of green roofs system.3.2 Limitation of Green Roofs SystemThe following are some of the limitations in installing the green roofs systemHigher capital costLack of awareness and knowledgeNo insurance cover is provided for green roofsDifficulty in maintaining and accessing roofs.4. RecommendationDue to globalization and competition there is a tremendous pressure on the construction industry regarding the time, quality and cost of the work. With the implementation of the modern construction methods such as Mivan Form work System and smart materials like Green Roofs the issues related to the time, cost and quality can be overcome. Although the initial cost of implementing such methods and smart materials are quite high the total amount saved at the end of the project life cycle is substantially more than the increase in the initial cost.The construction firms all over the world have been slow to adopt new innovation and changes. It is the need of time to analyse the depth of problems and find effective solution. Mivan system serves as an efficacious tool to solve the problems of mass housing fronts all over the world. The system has a great potential to provide high quality construction at unbelievable speed and at reasonable cost which was confirm in the report with the help of a case study. and so it is recommended to use Mivan formwork system over the traditional formwork systemAmid fears of global warming, deforestation, melting of ice on both the poles, increase in average temperature in attached few decades, green roofs can be looked up to as a potential solution which can help in optimising use of rain water, conserving energy, ameliorate aesthetical view of buildings and improving living conditions inside the building. Hence implementation of green roof is recommended as it will save large amount of resources.5. ConclusionIt can be concluded that the modern methods of construction such as Mivan formwork system are the key to meeting the demand for efficient, sustainable housing. Also the quality and speed must be given due consideration with regards to economy. Mivan formwork system not only helps in improving the quality and efficiency of the work but also has helped in maintaining the site safety.Anything that is good for the environment is good for humankind as well, so the investment funds in the green roofs is considered to be the best way in reducing the negative impact of humans on the environment. Green roofs not only reduce the adverse impact on the e nvironment but also help the people in reducing their bill for heating and cooling.
