What is modular construction?

Modular construction is a new way of building that happens off-site. In a factory, buildings are made as 3D, volumetric components (modules) that are then shipped to the site and put together. These sections, which are usually 60% to 90% complete with electrical, plumbing, and finishes already in place, cut down on construction time, site interruption, and waste while still following the same building requirements as more traditional approaches.

What are the main advantages of modular construction?

Modular construction has many benefits over traditional building methods. For example, projects can be finished 30–50% faster, quality control is better because the atmosphere is controlled by the manufacturer, and overall timelines are 30–60% faster. It also makes things more sustainable and cost-effective by cutting down on waste and labor.

Is modular construction environmentally friendly?

Yes, modular construction is seen to be more better for the environment than building in a traditional way. It is more sustainable since it cuts down on waste by up to 90%, uses less energy, and releases less carbon dioxide. Some important factors are production off-site and under factory supervision, less interruption on-site, and better energy efficiency in finished structures.

How does modular construction reduce construction waste?

By moving construction to a regulated industrial setting, modular construction cuts down on construction waste by up to 90% compared to traditional building methods. This setting allows for precise material cutting, better inventory management, and the capacity to reuse scraps, all while greatly reducing waste from debris, material damage, and transportation.

What is building in modules? Everything You Need to Know

Modular construction is a method of building that uses the same materials and follows the same rules and requirements as traditional building, but it takes around half as long. The building is erected off-site in a controlled environment. Buildings are made in "modules" that, when put together on site, look exactly like the most advanced site-built building, with no compromises.

More Green

The factory-controlled approach makes less waste, causes fewer problems on the job site, and lets for tighter construction.

More flexibility and reuse: Modular buildings can be taken apart and the modules moved or fixed up for a new use. This lowers the requirement for raw materials and the amount of energy needed to build a new building to satisfy the new need.

Less Waste: When you create in a factory, you recycle materials, keep track of your inventory, and safeguard your building materials, so you don't waste as much.

Better Air Quality: The modular structure is mostly built in a factory-controlled setting with dry materials, so there is no chance of a lot of moisture getting trapped in the new building.

Quicker

While site work is going on, modular buildings are being built at the same time. This means that projects can be finished in half the time of traditional construction.

Shorter Construction Schedule: Modular structures can be built at the same time as the site and foundation work, therefore projects can be finished 30% to 50% faster than with traditional construction.

No Weather Delays: 60 to 90% of the building is done within a facility, which lowers the chance of weather delays. People move into buildings sooner, which means a quicker return on investment.

Built to Code with Quality Materials: Modular buildings are built to the same building codes and standards as site-built buildings, and they use the same materials that architects specify for conventionally built buildings, such as wood, concrete, and steel.

More Intelligent

The same materials, building codes, and architectural standards are used to build modular buildings as they are to build regular buildings. Once put together, they look almost exactly like the ones produced on site.

Safer Construction: Building indoors lowers the chances of accidents and the costs that come with them for workers.

Building & BIM that are better designed: PMC uses modern BIM for visualization to look at how well the energy is used and find the most cost-effective ways to improve efficiency. This technology works best in PMC because the construction process is already a mix of systems, materials, and people, just like the program itself.

Limitless Design Options: Modular units can be made to match the look of any existing building or modular unit, and once they are put together, they look almost exactly like the ones that were erected on site.
