Modular Buildings

About Modular Buildings:

Modular building have been around for a long time and they have come a long way baby! There are so many advantages to modular construction today. They offer a high degree of quality control in manufacturing, accuracy in construction and with advances in technology, allow for easy and fantastic customization. Modular buildings are reusable, re-locatable, and expandable. Modular Buildings can be designed with A/C, exterior lighting, metal standing seam hip roofs, sliding doors, heat, electricity, to meet local snow load requirements, for interior or exterior installations and whatever you can dream of. You name it, we can have it built. No need to look for a general contractor and go manage and go through a long design and build process. you have a job to do. Order your building and get to the work that pays the bills. And never before have things changed so fast so Modular Buildings can be relocated and refitted to fit your changing needs. A huge investment advantage compared to a permanently built in building. If your considering a build-out of office or warehouse space please consider the modular building options you have today! Call us for prefab office building prices today so you will have a current modular prefab office building cost.

Adaptability and flexibility are real advantages of modular building. As your needs change and grow so can the product.

There are many saving going with modular construction. You can take out the time and cost associated with detaining an architect to design the building right off the bat. You can also eliminate coordination of framing, drywall, mudding, taping, sanding, painting and the other many aspects for traditional construction.

Think about dust with construction! It's not funny. =(

But....There is no construction dust and clean up with a Modular Building. =)

Modular buildings go in very fast for minimal interruption of your working facility.

And lets face it! when there is construction almost everyone stops to voice their opinion. Construction can be very distracting to your core business. Modular shows up and gets in done so fast!

Section 179 of the tax relief act classifies modular building as capital equipment. That means you can write off a modular building project over 7.5 years as compared to traditional construction that gets written off over 39 years!

Modular building is very "GREEN BULDING" since the components can be reconfigured and reused. Traditional construction usually goes right in the dumpster when relocation or remodel is required. Not only that, but now you have to start the entire process and double your expenses over. an architect, framers, drywall, paint and so on.

Imagine the quality difference in construction when you have the same staff putting together the same parts in the same environment with the same tools day after day that have assemble the same part thousands of times. It becomes perfection! A controlled factory setting using an assembly line process. While you are preparing the site the building is being constructed. When the site is prepared the building is simply set in place.

Modular Buildings utilize modular wiring. Modular wiring snaps together in half the time it takes to install traditional wiring. Just have the electrician bring power to the circuit breaker box and connect the circuits to the breakers. Modular wiring packages in modular buildings makes it easy to reconfigure and reuse if the building if changes are required in the future. All wiring components are factory tested and comply with all standard requirements. Snap together wiring systems eliminate the potential risk of field technician errors.

All welded steel construction! Can it be any stronger?

In-Plant Office on a Mezzanine

An In-Plant Office can be added on top of a mezzanine. It will add more floor space and still have an office that can oversee facility activity. The mezzanine can meet your many office configuration and specifications using structural steel. Instead of building out, you can increase your space by building up.

The raised office structure for staff members adds sufficient space underneath; freeing up additional space for other uses such and racking, service bays, and more.

History of Modular Buildings:

Like so many products modular buildings had their start with the US Military. During World War II a gentleman named Buckminster Fuller designed modular buildings which were picked up for use by the US Military giving modular buildings a well funded start. It can't be any surprise in hindsight how well modular buildings have done since. On a much smaller scale production of the automobile sure proved cost efficient as well as quality control. In a sense McDonald restaurant proved part of the point of the benefits by franchising so their hamburgers could be duplicated over and over again around the world. Each one is the same. Same is being done with modular building. There is no way a worker in the field can produce the same quality over and over again as compared to someone in a production facility with every part and ever jig in the exact spot they need for construction.

The Future of Modular Buildings:

The future of modular buildings can not be denied. Think of it as a Lego set. You choose the sizes that are most common and you produce them over and over again perfectly in quality and cost. Not only does the physical part of construction make so much financial sense but todays worker is fueling the growth of modular building construction. Today's worker is not interested in assembly line work. They are building robotics and servicing robots and writing software so things can be customized on the assembly line. and this is perfect because todays assembly line process are being robotized in giant steps. Some factories are even "dark" factories already in 2020! You stock the line in the afternoon and it runs all night, in the dark. low heat and many other energy saving features. As we know robots show up every day, never have any human resource issues, work full speed every day. Things we just can't do as humans.
