What are the Modular Buildings?
Modular buildings are constructions made up of modules or prefabricated sections manufactured at factories, transported to the site on a flatbed lorry, and installed as per the predetermined design. The construction of modular structures takes place in factories, in controlled settings, using standardized materials. Anywhere between 60 percent to 90 percent of the modular building is prefabricated in the factory, in modules capable of being transported to the building site. The transported modules are unloaded at the construction site and installed with the help of cranes. The remaining work, mostly fitments and finishing, is done on-site.
What are the different methods of Modular Constructions?
Modular construction comes in many types. Some modular constructions take place with the framing erected the traditional way, and modules fixed to the frame. Other modular constructions come with a metal or structural insulated panel. There are different types of basic structural design, such as closed box design, open frame design, and more. The best option depends on the purpose of the building and the site conditions. Several companies such as Elitesystems.co.uk offer different types of modular options, suiting different requirements.
The Design Specifications
Modular constructions adopt the same design principles and architectural specifications as that of traditional methods, meaning there is no difference in safety or durability of modular and conventional structures. Modular homes and structures are light weight compared to on-site constructions, making it safer against structural threats and natural calamities such as earthquakes. The modules are also reusable, meaning a modular building may be dismantled and the bulk of the materials re-used in another construction.
Why are Modular Structures Popular?
Modular homes have become popular of late, owing to superior quality, fast construction turnaround, and low costs. The adoption of lean manufacturing principles and strict attention to quality standards in the controlled environment ensures a high-quality product with low costs. Modular constructions get over in roughly half the time compared to conventional on-site construction, with far lesser environmental concerns or strain on natural resources. Since the bulk of the modular construction takes place inside the factory, the weather or other extraneous factors does not hamper or delay the construction. Quality control is easier in a factory set-up, and the assembly line process ensures far lesser wastage of materials. Modular constructions have a better finish, are highly energy-efficient, and have better acoustics compared to buildings constructed using conventional methods. Also, modular construction reduces the list of accidents and liabilities during the construction period.
What are the Concerns Related to Modular Construction
While modular construction has become very popular of late, some concerns remain. Since the modules are prefabricated, there is little scope for changes from the initial design. The viability of the process depends on the accessibility of large flatbed lorry and cranes to the construction site. Also, for all the advantages, the industry is still at a nascent stage and modular technology is still evolving. So changes are the order of the day.
