Every construction professional is aware that building can be expensive and a long-lasting undertaking. The likelihood of delays is higher than timely construction. They could be caused by administrative requirements, weather conditions, other unforeseeable circumstances, poor plans, insufficient employees, or various reasons. Long construction projects can adversely affect public perceptions of a project after the project has been completed if the projects have delays or annoy the people who live near the construction site. Additionally, specific projects require structure in a shorter timeframe than usually feasible for a typical construction project. Fortunately, there is a solution that can dramatically reduce the time to construct and costs: modular construction.
What exactly does “modular construction’ actually mean?
According to the Modular Building Institute, the largest industry trade association and most reliable source, “modular construction is a process in which a building is constructed off-site, under controlled plant conditions, using the same materials and designing to the same codes and standards as conventionally built facilities – but in about half the time.” Modular building is somewhat of an umbrella term that encompasses a variety of kinds of construction:
- The volumetric design is a method that involves the construction of whole rooms or parts of rooms, complete with floors, walls, and ceilings are constructed in a factory setting and later transported to the final location to be assembled. This kind of construction can be utilized for permanent and modularly relocatable projects (buildings that aren’t built to be moved, versus ones that are a hotel as opposed to the temporary classroom).
- Panelized construction is a method that involves the construction of exterior and interior wall panels are constructed in a factory environment and later transported to and set up on the construction site. The remainder of the structure is built on-site.
What are the advantages of modular construction compared to traditional construction methods? Can it truly save money?
Modular construction will help save money, but there are other advantages. Modular construction’s most crucial benefit is its time-saving and faster rate of return. Because modular construction permits industrialized assembly, which occurs concurrently with the preparation of the site and site preparation, the time needed to construct the structure could be drastically diminished. When the site is prepared (foundation cleared, plumbing installed set, foundations laid, and so on), the factory-built components are ready to be erected. Hotels that are built modularly are a good example. It can be opened and make money 30% to 50% faster than a traditional hotel.
Other benefits include better worker security (workers are all in a safe, secure environment instead of working in precarious heights or less controlled areas) and improved productivity. Improved schedule certainty (late changes and weather delays are significantly reduced by modular construction) and increased cost predictability.
Is modular construction sustainable?
Modular construction is regarded as an environmentally friendly alternative to traditional methods of construction for several reasons:
- Greater versatility as well as reuse. Modular structures can be disassembled, and the modules repositioned or rebuilt for use in a new way, decreasing the need for raw materials and reducing the amount of energy used to meet future demands.
- A lesser amount of material waste. In factories, it is possible to eliminate debris by recycling materials, regulating inventory, and securing construction materials.
- Improvement in Air quality. Since the modular structure has been substantially constructed in a factory-controlled setting made of Dry materials, the risk of excessive moisture levels to be attracted to the new construction is wholly eliminated.
Can it be used to construct any structure? In what circumstances is it more appropriate to use modular construction instead of traditional methods?
Every type of structure can be constructed modularly. However, to be able to do this, the building must be thought of and built to function as such. Modular construction is usually selected when time is a factor or space is limited. For instance, in Europe, urban areas are generally constrained by roads and other buildings. So the traditional method of the building (bringing construction materials and personnel on-site for a prolonged duration) could be inconvenient. When you build modularly, you will require a crane and significantly fewer workers to build the structure in less time. Also, in urban areas, eliminating noise pollution is a further benefit.
What are the technical requirements needed to implement it? For instance, do you have design restrictions or security requirements?
In contrast to traditional construction, which is a more straightforward process in which modifications to the design are made even after construction has started (often leading to delays), modular construction demands designers to collaborate and finish their work before. During this process, modular construction-permanent modular construction, most notably–usually relies on advanced BIM to assess energy performance and identify the most cost-effective efficiency measures. The plans are then handed to the manufacturer for industrial construction and prefabrication.
