Modular buildings are actually off site based construction method. It’s clear from this sentence that what actually does modular building means. Modular building is also called as Pre Engineered Steel Building (PEB). The individual building components are actually designed and engineered at factories. From the factories where they are manufactured, they are transported to the location where they need to be installed. At jobsites they are assembled using nut and bolt technology. Traditional method which we used to follow here was building all the components at the jobsite itself and step by step assembling of the parts. Modular building concept made a change to that traditional method of construction.
Traditional methods were slower compared to modular building. Modular building technology made almost 50% savings in time. Modular building also provide advantages such as flexibility in expansion, environmental friendly, earthquake resistance, single source responsibility etc. They also make impact such as faster return on investment, lesser project cost and the green building features etc.
Modular building provides facility of easy accommodation to the changes in plans about construction at the execution stage also. Modification and expansion can easily be done in this technology. Experienced engineers can make optimized designs by intelligent use of steel. Steel can be efficiently used such that the total production cost of the structure can be very well minimized.
In our country we have many traditional construction materials so there was a difficulty in minds of people in accepting steel as a construction material. Later it get accepted in some simple buildings and warehouse applications. After that mindset among people got changed and accepted steel as an alternate construction technology. The fastness that offered by steel construction as well as the earthquake resistance it provide also made a big impact in changing the mindset of people. The steel has also got good resale value so that it can be sold as scrap. Nowadays PEB is used in almost all industry segments like warehouses, shipyards, showrooms, supermarkets for different type of applicants. New application areas such as heavy industry structures, high rise buildings, and multilevel car parking structure are being explored.
In metro rail projects this technology is used since traditional construction method is not possible due to heavy traffic and lack of space. Cities are getting filled with vehicles day by day and cannot afford big construction equipment’s between those. This technology proves to be ideal solution for such type of construction. Since they are fabricated at another place only job is to do the assembly at location. This will result in faster project completion hence reducing the total production cost too.
PEB had not influenced much in residential sector but the scope of growth is more when we look at the facilities and advantages provided by PEB. PEB can be used well in construction of houses for the homeless. Such projects looks for low cost construction. Modular building technology using steel is better option for such projects. It gives provision for low cost homes for the homeless. Reliant Institute of Technology is an authorized TEKLA training center in KERALA
