Top Modular Construction Companies: Key Success Factors

The Key Factors Driving the Modular Construction Industry

Marriott recently announced plans to build the world’s tallest modular hotel in New York. The 360-foot tall tower will feature 168 rooms, a modular roof, and a modular rooftop bar. Each module will contain a fully outfitted guest room right down to the bedsheets and pillows. Marriot says modular construction reduces the typical construction timeline, cuts down on-site waste (and noise), and improves quality because of factory-level precision.

It is just another example of how modular construction has gone mainstream. From large-scale modular hotel projects to prefabricated buildings to modular office buildings, business is booming for prefab construction companies.

Modular Construction Market Size

The modular building industry in the U.S. has grown dramatically. It has literally doubled in size over the past five years and now accounts for $8 billion of revenue annually.

One of the more encouraging modular construction statistics is that more than 80% of contractors are now using some form of offsite construction methods, including prefab and modularization. Offsite modular construction statistics like these are reflected in the confidence contractors have about the anticipated growth in the portable building market and the modular construction market in the year ahead. By 2030, global consultant McKinsey & Company, projects that modular construction could grow to a $130 billion industry in the U.S. and Europe.

Which Are the Key Factors Driving the Modular Construction Market?

Contractors are increasing their offsite building for these five key reasons:

  1. Improve labor productivity
  2. Improve job site efficiency
  3. Maintain schedules
  4. Manage costs
  5. Improve quality

McKinsey & Company reports that modular projects have accelerated timeliness by 20-50% and that real estate players that are making the shift to modular construction have the potential to realize construction cost savings in excess of 20%.

Outsourcing of modular building and prefab construction has also increased to control costs and combat the continuing shortage of skilled labor in the workforce.

What Are the Key Trends in the Modular Construction Market?

Overall, construction industry growth is forecast to continue with significant upticks in the modular building industry. Here are some of the other key modular construction trends identified in the Q4 2019 Commercial Construction Index, published by USG and the U.S. Chamber of Commerce.


Hiring continues to be brisk with most contractors expected to add to their staff in the next two quarters. However, the shortage of skilled labor continues to be an industry problem. 89% of contractors surveyed reported a moderate or difficult time finding qualified workers.

Modular builders are also showing concern about rising wages due to worker shortages.


When it comes to financing, access to working capital used for day-to-day operations is expected to stay the same.   Access to owner financing, where sellers finance purchases directly with buyers, is expected to get easier over the next six months.

Material Costs

Contractors expect to spend more on tools and tech in the near term. While there is less concern about the impact of fluctuations in material costs, the potential of tariffs on key materials is unknown at this time. 

40% of contractors anticipate higher costs for steel and aluminum to negatively impact their businesses for the next three years.

U.S. Prefab Construction Startups

Several modular construction startups are attracting attention and significant investor dollars.

Plant Prefab is focused on custom homes that arrive on site 90% complete and can be installed in just one day. The name derives from the company’s focus on sustainable construction and it counts Amazon as one of its major funders. 

Blokable is creating modular homes, retail spaces, student housing, and offices. It just landed $23 million in funding to expand operations.

Module is another startup with a unique approach in the modular construction industry. Their prefab homes are designed to expand. Roofs and walls can be removed allowing owners to add on in the future.

FactoryOS leverages tech to build modular and prefabricated buildings. It burst onto the scene with a $25 million contract with Google to build short-term housing for employees that couldn’t afford housing in the San Francisco Bay area. It recently built a 5-story, 110-unit housing project in Oakland in just 10 days.

Best Modular Construction Conferences 

If you are looking to learn more about the modular construction industry or stay on top of emerging trends, there are a few modular construction conferences this coming year.

  • The 2020 World of Modular, hosted by the Modular Building Institute, is the largest offsite construction expo in the U.S. for the year. It takes place on March 9-12, 2020 in Orlando.

Events including the Construction Institute Summit and the 2020 Construction Technology & Innovation Conference will also offer programs of interest to the modular and prefabrication builders and contractors. 

In addition to attending a modular construction summit, the Modular Home Builders Association is a resource for education and promoting prefab construction and modular building.
