Panel builder/integrator cuts install time; improves efficiency

BDI identified two prime areas to improve the panel integration process: reduce installation time and decrease labor costs. Because the end-users’ panel requirements constantly change, BDI needed to build panels that easily accommodated upgrades.

Indiana-based BDI Engineering, Inc. offers electrical panel construction, installation, and startup services for process control, industrial refrigeration, power management, and food processing applications. Founded in 1998, BDI started as a simple panel-build shop that has today expanded into a turnkey solutions provider capable of designing complex panels for clients such as 3M, Coca-Cola, Dean Foods, Ford Motor Company, General Motors, Johnson & Johnson, Nestle, and PepsiCo.

“The integrated expertise of industrial, electrical, and mechanical engineering professionals enables us to zero in on the complete solution to a given problem,” said Brad Johnson, president and founder, BDI. “Having this capability allows our customers to deal with one small company for any control project, knowing that we have years of experience in the associated field of need.”

Rising installation time and cost

To compete with larger, more established system integrators, BDI needs to outperform its competitors in cost, quality, and delivery time. The traditional approach to building panels was inefficient for BDI, particularly when it mounted and wired the components into the panel. As panels became more complex, the installation time increased, resulting in higher labor costs.

Because traditional wiring of panels was inefficient and relied heavily on the expertise of engineers, it often resulted in wiring errors that affected delivery schedules. Panel upgrades and maintenance also were costly and time consuming. Often, the machines were required to shut down for an extensive amount of time for a simple upgrade or routine maintenance, resulting in lost productivity. Additionally, it was difficult to find local service and support for hard-wired panels. And, because BDI works on a deadline-driven schedule, the specified components and documentation needed to be delivered on time consistently.

BDI’s solutions

BDI selected Rockwell Automation and its Allen-Bradley distributor, Wabash Electric, to provide a portfolio of panel products. One of these products was the Bulletin 141A MCS mounting system, a part of an Allen-Bradley Modular Control System (MCS) busbar mounting system. This system offered BDI the advantages it was looking for over traditional mounting approaches, including:

  • Installation — The system that BDI implemented almost eliminates the need for drilling and tapping holes because power distribution is reduced to a single feed for multiple automation components. Using pluggable modules, BDI can simply snap motor starters onto the busbar and wire only motor load connections.

  • Reliability — Using the mounting system, BDI has increased the reliability in its panels. The selected system offers superior reliability of busbar contacts, and it extends “Type 2” coordination to starters mounted onto the busbar.

  • Flexibility — In the past, maintenance and upgrades were difficult and time consuming. Now BDI is able to perform upgrades considerably faster than with the traditional, hard-wired mounting systems.

    • “When building a panel, the mounting system allows us to leave spare slots for future upgrades and expansions as needed,” Johnson said. “When a customer wants to expand or service a panel, we can simply snap in additional starters by isolating key areas through busbar-mounted isolation circuit breakers rather than disabling the entire system.”

      The mounting system also provides a clean and organized look because of reduced exposed wiring and a structured layout. To solve its system design challenges, BDI uses the MCS Star Configuration Software that allows BDI to efficiently configure the MCS Starters and lay out complete assemblies on the MCS Mounting System. The software performs engineering calculations to assure that the system is properly designed and warns users of potential design problems.

      Results

      Using the Allen-Bradley Modular Control System, BDI reduced its installation time by as much as 30% because the company no longer needs to assemble starters, drill or tap holes, mount components onto the DIN rail, or wire all components individually. With the selected products, starters are pre-wired and can be easily mounted onto the busbar. The mounting system does not require holes to be drilled for individual starters, which saves BDI valuable installation time and labor costs.

      BDI also noticed significant savings in panel space using the mounting system. The panels featuring busbar-mounting systems are more compact than traditional mounting arrangements as a direct result of reduced wiring.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
