CUSTOM PREFABRICATED ENCLOSURES

Prefabricated Building Solutions

Built Differently for Spaces That Demand More

When your project involves tight spaces, complex layouts, difficult site access, or demanding timelines, a standard prefabricated building may not be enough. RDI Enclosures specializes in custom prefabricated buildings engineered around the realities of your site and application.

Rather than forcing your requirements into a one-size-fits-all solution, we design and manufacture each enclosure to deliver the durability, flexibility, and installation efficiency your project demands. Our proven approach gives customers a high-quality building engineered for long-term performance even in locations where conventional construction can be difficult or impractical. See our work.

Standard Buildings

A Smarter Way to Build

Many prefabricated building manufacturers rely on standardized designs and conventional installation methods. RDI takes a different approach.

Every RDI enclosure is precision-built in our advanced manufacturing facility. By completing much of the construction in a controlled environment, we maintain greater control over quality and consistency while minimizing the work required at your site.

Once complete, the building is efficiently shipped for rapid on-site assembly, making RDI an ideal solution for tight spaces, complex layouts, and hard-to-reach locations where crane access may be limited or unavailable.

Our streamlined process can allow your building to be fully operational within a day of delivery, helping reduce installation time, minimize site disruption, and keep your project on schedule.

Built to Meet Code, Compliance, and Environmental Demands

RDI buildings are engineered to the highest standards and major industry codes, such as IBC, NEC/NFPA 70,
UL standards, and local regulations. Each structure is designed with full consideration of wind load, snow load, and site-specific structural requirements.

Engineering validation includes structural calculations, material selection, and quality control checks throughout production. Buildings can be customized for extreme environments, such as high heat, freezing temperatures, coastal corrosion, and high-wind or seismic zones. We can also customize insulation and energy efficiency and tailor it to meet specific environmental and operational needs. Our designs prioritize safety, compliance, and long-term reliability across highly regulated industries.

RDI is your trusted partner for delivering fully compliant, engineered prefabricated solutions that are thoroughly tested. We have placed buildings in every location and environment around the world that you can imagine. From mountain tops and offshore rigs to roof tops and confined spaces. We have the resources, versatility, and experience to meet your project demands.

Scalable Designs to Support Future Growth

Prefabricated buildings are designed with modular scalability, allowing for expansion without full reconstruction. Structures can be extended in length, reconfigured internally, or adapted for additional equipment. Buildings can accommodate future operational changes, including increased capacity or new systems.

Many clients opt for a phased project implementation, which allows them to start with their current needs and expand over time. Using a phased implementation with a scalable design reduces the need for costly rebuilds or facility replacements. Expansion can be completed with minimal disruption to ongoing operations.

This form of long-term infrastructure planning improves lifecycle value and return on investment.

Frequently Asked Questions

  • What is a custom prefabricated building?

    A custom prefabricated building is a structure that is engineered and manufactured off-site, then delivered for fast assembly at its final location. These buildings are designed to meet specific project requirements, including size, layout, equipment integration, and environmental conditions, offering a faster and more efficient alternative to traditional construction.

  • How long does it take to install a prefabricated building?

    Installation timelines are significantly shorter than traditional construction. In many cases, prefabricated buildings can be delivered and made operational within a single day, depending on site readiness and project complexity. This rapid deployment helps reduce downtime and keeps projects on schedule.

  • Are prefabricated buildings durable enough for harsh environments?

    Yes, prefabricated buildings are engineered to perform in demanding environments. They can be designed to withstand extreme temperatures, high winds, heavy snow loads, and corrosive conditions. Material selection, insulation, and structural engineering are all tailored to meet the specific environmental challenges of each project.

  • What customization options are available for prefabricated buildings?

    Custom prefabricated buildings can be configured with a wide range of options, including HVAC systems, electrical panels, fire suppression, lighting, insulation, specialized doors and windows, and equipment integration. Designs can also accommodate unique layouts, access requirements, and industry-specific needs.

  • How do prefabricated buildings reduce overall project costs?

    Prefabricated buildings help reduce costs by minimizing on-site labor, shortening construction timelines, and improving quality control during manufacturing. Because systems are built and tested in a controlled environment, there are fewer delays, less rework, and more predictable project outcomes.
