PCR vs Jobsite Built
With a PCR®
, Powell is responsible for the complete engineering and design while with Jobsite Built the customer must design the electrical system and the structural design and then package the two.
With a PCR
, Powell is responsible for meeting all applicable codes standards including local/state codes, ANSI standards, OSHA. With Jobsite Built the customer must research and apply these standards.
A Powell PCR
is tested prior to shipment by inspection personnel that are completely familiar with the project and the construction techniques. With a jobsite built structure, the completed assembly must be tested by personnel that are unfamiliar with the interconnected equipment and systems. This makes troubleshooting in the event of a problem more complicated.
A Powell PCR
is portable and may be relocated at minimal cost. A Jobsite Built structure is permanent and cannot be moved.
Powell construction is customized to the region. There are Power Control Rooms in every state and more than 70 countries. Canada has a specific design PCR-R®
that is perfect for the Canadian market. Jobsite Built structures must be designed from the ground up each time.
One Stop Shop
The Power Control Room (PCR®
) concept originated with Powell in the early 1960's. In one facility we custom engineer and manufacture your complete project. From beginning to end our team of Project Managers and Engineers work to produce a tested and ready-to-go solution for your project. Integration expertise is at the heart of our business model as we take on all the management of the project so that you can focus on the bigger project tasks.
Our Project Management
Team provides you with one point of contact to manage every aspect of your job from commercial to technical to scheduling to logistics we can handle things for you. It is simply what we do and the value of letting our expertise work to make your project a better one cannot be underestimated.
Consider carefully your other choice, to have a manufacturer with product sourced from many locations and a third-party integrator. The complexities involved make that a dangerous choice. There is danger of unresolved integration issues, there is danger of unpredictable schedule delays and there is danger of miscommunication.
Do not take the risk. Let Powell and our experience give you piece of mind as we deliver a completed and fully functional Power Control Room of any size, to any place, and at any time
Wall / Roof System
A Powell PCR®
is constructed with a structural steel base providing a live floor load of 250 lbs./square foot. Projects requiring greater load capacity can be accommodated. Structural calculations for all structural members are certified by a professional engineer and performed on your specific geometry.
The wall system consists of an interlocking exterior panel and interior wall liner. The combination of exterior and interior liners provides the required mechanical strength and a standard wind load of 125mph. Higher wind loads can be accommodated. As a standard, wall panels are fabricated using galvanized steel, but for specific applications can utilize aluminum or stainless steel. Wall height is dictated by the project requirements and shipping restrictions.
The roof system design is similar to the wall design and may be sloped or peaked in design. While consideration is given to jobsite conditions, the minimum snow load is 40 lbs./square foot. The ceiling is used to support installation of conduit and lighting systems.
Walls and roof may be insulated for normal, cold or very hot conditions. Additionally special construction can be included such as two-story, shipping splits and floor systems.
The environmental design of your PCR®
is completely custom-engineered. A variety of heating methods are available including electric wall-type, space heaters, or combination heating/cooling units. Thermostats are a standard.
Wall mounted cooling units are standard. Air conditioning is sized based upon a variety of factors, including: installed environment; heat gain from mounted equipment; insulation level of floor, wall and roof; as well as the desired operating temperature. For larger PCR
projects the HVAC system may be roof mounted, pad mounted, include built-in redundancy, or use separate condenser and air handling units.
can be constructed for operation in Class I, Group D, Division 2 areas using positive air pressure system.
For highly contaminated areas the PCR
can be designed to include filtering systems to remove air contaminants that may be harmful to equipment installed within the PCR
enclosure such as SO2
Codes / Standards
The Powell PCR®
will comply with National Electric Code requirements for equipment installation and clearances as well as OSHA requirements for safety including proper operating lighting levels, emergency lighting and panic door hardware. Additional safety features may be incorporated for compliance with identified state and local codes. The Powell PCR
is constructed in accordance with The National Electric Code and ANSI/IEEE C37.20.2 Section 5.2 for electrical equipment enclosures.

One contract or purchase order
One source design responsibility
One site for fabrication, testing, and commissioning
One project management team
Water Front Facility
Our 64 acre facility and 600 foot bulkhead is located in Houston with direct access to the Houston Ship Channel, the fourth largest port in the United States. Transportation concerns are a critical element due to the magnitude of these projects. Our extensive experience with shipping coordination by truck, rail, or water can be a big benefit for you and your module.
A highly experienced engineering staff assures your project of an efficient and single source design
responsibility. Powell delivers optimized turn-key performance through our knowledge of industry standards, code restrictions, certifications, and compliance.
We provide an efficient and safe design while meeting the unique requirements of each project. Our experience and know how is a benefit to your project.
When your order is placed, Powell assigns an experienced Project Manager to your project. This one point of contact for the duration of the job is coordinated with your needs to provide schedules and updates as required. Customer site visits during all phases of the project are welcome and encouraged.
