What is Modular Construction?

  • Modular construction is an innovative process in which a structure is divided into sections and manufactured in a factory-controlled environment. To expedite product delivery, the building’s site is usually prepared at the same time.
  • Modular construction is also sometimes called Prefabricated, Prefab, or Pre-engineering. All terms refer to buildings whose components are manufactured off-site.
  • Modular building manufacturers observe the building codes of a product’s destination, meeting or exceeding all local standards.
  • Modular construction saves time and money because each module’s structure, mechanical systems, electrical systems, plumbing systems, safety features, and interior finishes are completed prior to shipping. Assembly and connection takes place on-site.

How important is Safety at Teton Buildings?

Safety is one of the core values at Teton Buildings. Through a joint effort from Teton’s employees and management staff we have developed a strong safety culture to ensure a safe and healthy environment for employees, customers, and vendors alike. With this culture, we continue to drive change and improvement. A prime example of Teton Buildings’ commitment to safety – in our Casper, WY facility all of the management staff have completed the OSHA 30 hour training course and all other employees the OSHA 10 hour training course. The Bogota, Colombia plant also maintains the RUC certification which is a government program that requires an annual re-certification for sound health, safety, and environmental practices.

What are the benefits of Modular Construction?

  • The chief benefits of modular construction are cost and speed.
  • Modular buildings are constructed in a factory using cost-efficient materials and methods, which makes modular structures less expensive (even after factoring in transportation costs).
  • Off-site factory construction also means no weather-related delays or damages. Since site preparation typically takes place at the same time as construction, a modular building is typically ready forty to fifty percent faster than conventional construction.
  • Because it takes place in a controlled setting, modular construction is also inherently greener than conventional construction. Modular construction minimizes air and noise pollution, decreases waste of materials and reduces the environmental impact of on-site construction.
  • Finally, factory production means tighter manufacturing specifications and therefore greater value for your money.

What is a typical delivery turn-arround for modular buildings?

  • Modular buildings can be fully constructed and ready for occupancy weeks or even months ahead of the time required for traditional construction. A forty to fifty percent savings in time over conventional construction methods is typical, accomplished in part by simultaneously preparing the project site while constructing the building’s modules. This is called “concurrent construction”.
  • Concurrent construction means faster occupancy, faster revenue generation, and reduction or even avoidance of some expenses related to conventional construction.

What are the size limitations of modular buildings?

  • While modular buildings can vary greatly in size and shape, practical transport issues limit the size of individual modules. In the US, module size limitations vary from state to state, based on overpass heights and the US Department of Transportation’s requirements.
  • These size limits on the individual modules do not limit the size of the overall buildings. The modules are designed to link together and stack on top of one another meaning that any building can be constructed using modular units.

What are modular buildings constructed from?

  • At Teton Buildings, the material of a modular building depends on its use. The primary structures of smaller buildings are normally made of wood. Buildings that require wider open areas are usually constructed from steel.
  • However, because modular construction follows the same practices as site-built construction, Teton can construct buildings out of the same materials found in traditional construction with few limitations.

Can I expand or move a modular building?

Yes. One of the great advantages of modular buildings over conventional on-site construction is that they can be expanded and relocated. An integrated floor and undercarriage will greatly facilitate relocation. If you know you may want to expand or relocate a building later, we can factor this into the design.

Can I earn L.E.E.D. points with modular construction?

Yes! Teton Buildings has been working with our clients for years to ensure that they meet their energy goals including having their buildings certified by the U.S.G.B.C.

What sort of energy efficiency can I expect?

In custom modular buildings, energy efficiency is controlled by the same factors that control all building environments. These include design components such as quality of insulation, glazing components (windows), and HVAC system performance. A modular building can be customized to any energy efficiency specification, including the requirements of energy efficiency levels for L.E.E.D. certification by the U.S. Green Building Council.

Aren't all modular building designs dull and "boxy"?

  • Since Teton Buildings began in 1967, there have been great advancements in modular building techniques. Today’s designers can use modern, high-quality materials that do not need to compromise aesthetics for cost or turnaround time. Gone are the days when modular buildings were boring, boxy structures with little aesthetic interest or appeal.
  • Permanent modular buildings can be built as single one-story buildings or multi-story structures. Whether the building is a medical center, school, or government facility, its design can be tailored to each client’s unique needs. Exterior architectural finishes such as brick or stucco, as well as design innovations such as exposed aggregate architectural panels can make a modular structure blend into any neighborhood.
  • For the internal spaces, architects and interior designers collaborate with our clients to develop architectural touches, interior finishes, and the workflow of environments to align with each application.

How secure are modular buildings?

  • Modular buildings can be made as secure as required.
  • For isolated building sites, windows and doors can include extra protection against vandalism and break-ins.
  • Modular classrooms can be integrated into a school’s security system.
  • Buildings can be made blast-resistant for government or industrial applications.
  • Sections of buildings can be designed to be more secure in the applications of personnel holding cells or SIPR/NIPR rooms.
