Building houses takes months, if not years, when you’re doing it the traditional concrete-built way. Over the years, there have been some refreshing and innovative ideas as to how we can come up with better ways of building homes. Dhaka, being overpopulated much like the other cities in Bangladesh, faces a huge problem since there is a good chance we might run out of space soon.
But that’s exactly why we should adapt to newer technologies.
No matter where you are planning your residential or commercial building, exploring other options will help you decide what will be the best choice for you. Let’s take a look at the possibilities that you can introduce in Bangladesh!
Modular homes (not to be confused with mobile homes) are primarily constructed on a factory and later brought to the site on a truck where it is set by a crane and finished. By doing so, you can separately build each room according to your designs and the builder of your choice will add up the finishing touches. Modular homes offer you different prices for different designs for your home.
This method is similar to modular homes but with a little twist. Prefab technology uses factory made components to construct homes instead of brick and concrete such as wood, gypsum, cement, steel frames, etc. But similar to the modular way, the pieces are kept un-assembled, brought to the site and then put together. An entire building can be designed using architecture software. Prefab technology definitely reduces the amount of time needed to build a home compared to the conventional technique.
This type of constructing method depends on soil bearing capacity. This framing includes construction of the foundation, columns, floors and the beams, all with steel. There are several ways of implementing steel frame construction and the amount of load it can bear which is decided after the soil assessment. The different sections of steel are usually produced offsite and then installed onsite. This method definitely has a lot of advantages compared to other methods (and very applicable in Bangladesh!). For instance, steel is tensile which means it has a higher strength to weight ratio which makes it almost 30-50% stronger than wood.
On the other hand, deformation in steel takes place in stages. So, if any damage occurs, that leaves plenty of time for occupants to move out. Moreover, assembling steel sections takes very little time; hence, constructing a building using steel framing is less time-consuming compared to conventional ways of construction.
However, another major drawback is that it’s not fire resistant and may lose almost half of its strength if a major fire accident were to occur.
This construction method is a game-changer. By implementing this method, construction costs can be drastically reduced as well as the duration of construction compared to traditional construction methods. Using 3D printing, architects will be able to produce designs and structures without any restrictions. Along with affordability, complex designs can be done onsite at a quicker pace. Since the parts are produced by a precision machine, the amount of waste material is significantly reduced, making this method highly environmental-friendly.
