Main Industries That Use Prefabricated Commercial Buildings

Modular buildings can find a place in just about any industry. Some of the top industries for commercial modular buildings include:

#1 – The Healthcare Industry

Modular buildings can be erected more quickly than traditional site-built structures, which makes them ideal for the healthcare industry. In fact, healthcare is one of the largest consumers of modular products.

Modular construction made it possible to build a 300,000-square-foot hospital in just six days in China. These prefab structures housed more than 1,000 patients fighting COVID-19.

#2 – Commercial Construction

Commercial modular buildings are naturally at home in the construction industry, and they have been for years. It’s common to find portable, modular offices on construction sites, which provide workers with a comfortable place to manage the project.

In some cases, temporary modular buildings are used alongside traditional construction.

#3 – Education

It’s common for permanent and modular buildings to work together on campuses across the world. Modular classrooms may be placed on campus to house students while parts of the school are being renovated or additions are made to the structure. Additionally, modular gyms, locker rooms, offices and more allow the educational facility to add on to its amenities without having to deal with the expense and hassle of a major construction project.

#4 – Hospitality

Modular buildings may not seem like they have a place in the hospitality industry, but they do. Marriott constructed the world’s tallest modular hotel in New York City. According to Marriott, modular buildings offer advantages, including:

  • Less noise disruption
  • Less waste
  • Higher-quality construction due to the factory-level quality control

The hospitality industry is one of the largest consumers of modular products.

#5 – Energy Industry

Modular buildings have been in use in the energy sector since colonial times in Massachusetts. The story is still the same today.

Modular homes are often found where industry players drill for the oil that powers society. Because these locations are often remote, workers live in modular homes in self-made neighborhoods. These workforce neighborhoods often have everything workers need for a comfortable life, including theater rooms, cafeterias, recreation areas and more.

#6 – Government Buildings

Modular structures are found on government properties across the country, including fire departments, national parks, visitor centers, police departments and department of transportation locations.

What to Consider When Selecting Manufacturers for Commercial Modular Buildings

Commercial modular buildings are an investment and an asset for your business. When choosing a builder for your construction project, there are a few things to consider:

  1. Speed. Can the builder help you finish the project on time and on budget? Modular manufacturers will provide estimates for your build, so you can find a company that meets your needs.
  2. Location. Is the manufacturer local or will they have to ship the building to your site, potentially hundreds of miles away? Does the manufacturer have offices in your state? Can they connect you with builders to finish the unit when it’s delivered on-site if the company isn’t local?
  3. Reputation. Check the reputation of the company on the Better Business Bureau and relevant review sites, such as Google.
  4. Customization. What, if any, customization options are available? Can you choose custom flooring, solar, numerous size options and more? If you don’t want to customize your build, how many design options are available to choose from to meet your needs?
  5. Cost. What options are available in your budget? Pricing varies greatly from one manufacturer to another, and your builder must offer options in your price range. Is leasing an option? Are there financing options available?

You’ll want to do your due diligence when choosing a company for your commercial modular buildings. If you follow the tips above and consider some of the manufacturers above, you’ll have a higher chance of a successful build.
