The Modular Construction Process Defined

Modular buildings are constructed in sections, like building blocks. The modules are completed much quicker, are less expensive and are more flexible than conventional construction.

Efficiency from
start to finish.

No matter the size of building, the building process is the same:

  • From a customer’s dream we produce a custom design, then we transfer that design to blueprint and start construction. 

  • Work on the modules can start in our factory before the foundation is poured. That shortens construction time by weeks or months!

  • Modules are trucked to the site.  They are between 80 and 90 percent complete when they arrive.

  • Cranes lift the modules into position, crews link the units and seal the exterior mate lines. 

  • Interior finish work is quickly completed while outside landscapers add curb appeal.

You have questions, and
we have answers.

What is Modular?

It is just a different method of building offices, health care centers, schools and almost any other type of building you can imagine. Modular construction employs factory techniques to improve quality, shorten manufacturing time, and reduce cost. While it is not quite an assembly line approach to manufacturing buildings, the economies of scale, increased worker efficiencies, and reduction of delays from weather or vandalism add up to greater speed at less cost.

So how does it look? 

You drive by modular buildings every day. They can look just like any other building around. Exteriors can be as wide ranging as any other style of construction. Interiors can have brand name cabinets, plush carpets and all of the other hardware associated with any other building. Because of the efficiencies of modular construction you may be able to upgrade the exterior look and interior décor.

Are there other significant differences?

There is one other difference worth noting: flexibility. A modular building is constructed to be quickly assembled and easily disassembled. You can reconfigure a modular school to meet changing student numbers. That is unlikely with a standard brick and mortar facility. In fact, with modular, you can disassemble and move the entire building to another location and be back in business within a relatively short period of time.

What is the construction process like?

Whitley works through a network of independent distributors. The distributor helps you arrive at a floor plan, helps with material selections, works closely with us to create drawings, to obtain the necessary government approvals and to make sure the finished building is delivered, assembled and finished the way you expect.

Do I need an architect?

We have an experienced in-house design and engineering staff which alleviates the need for architects. We do, however, work with architects and value their services.

How long does construction take?

Two months, maybe three, perhaps longer for more complicated buildings.  If your needs are more elaborate it takes a month to two months to design the building, choose colors and obtain approvals. After that, construction take anywhere from a few weeks to a few months depending on the complexity, and on-site assembly a few days more. It is a relatively rapid process. In fact, we can begin construction of your building while you are preparing its site. You can't do that with old-style construction. 

What size buildings can be manufactured?

They can range from small "in-plant" offices to over 100,000 square foot multi-story office complexes. We have built schools, office centers, child care facilities, health care centers, MRI labs, airport terminals, and more. In fact, we have thousands of floor plans already on file for you to choose from if you want a turn key solution for your building needs.

Do your buildings meet code?

Yes. In many cases they exceed today's codes by offering greater energy efficiencies and weather resistance. They are designed to meet ADA requirements and fire safety rules as well.

Does transportation of the finished building eat up other savings?

No.The cost of transporting the building to your site is quoted with the initial price. Old-style builders also transport materials and supplies to the site. The difference is that their materials are vulnerable to theft and vandalism while they await use. Our buildings arrive secure and ready to finish.

Can you move or rearrange our building?

Yes. Each module is a unit. There are points where electrical, plumbing, ventilation and other systems meet. They can be quickly disconnected, mate lines cut and the building lifted from its foundation. Then a truck hauls it to the next site where the process can be reversed, quickly. Adding another section to an existing building can also be finished faster than by conventional builders.
