Pre-Fab Central Utility Plant Key to Earlier Opening for Maryland Medical Center

04.12.2020 in News

The University of Maryland Capital Region Medical Center opens its doors next month to provide health and medical services to Prince Georges County, a suburb of Washington, D.C. An earlier-than-originally-anticipated opening was made possible by a time-saving approach to construction of the central utility plant.

The new 11-story, 600,000-square-foot hospital, originally called the Prince George’s Regional Medical Center, features a pre-manufactured central utility plant that was instrumental in the hospital opening sooner than what would have otherwise been possible.

Leach Wallace, a WSP company, provided the University of Maryland Medical System project with mechanical-electrical-plumbing (MEP), fire protection, electrical/lighting and fire alarm design for the project, which is set for completion in November. The building, designed by Wilmot Sanz Architects, will open to patients by spring 2021.

“This facility will serve a lower income community and will provide state-of-the-art, modern healthcare in an area that deeply needs it,” said Michael Lamdin, WSP USA project manager. “This project is by far the largest – and the MEP systems the most complex – that I have had the chance to work on as project manager.”

Design began in late 2014 and construction for the $285 million project began in October 2017. The central utility plant, which provides heating, cooling, electricity and other utility services to maintain a comfortable environment for the patients, faculty and staff at the medical center, was installed during the summer of 2019.

The plant is now operational but due to COVID-19 concerns, the public opening of the medical center has been delayed until spring 2021. The medical facility was designed to meet U.S. Green Building Council requirements for LEED Silver certification.

The University of Maryland Capital Region Medical Center includes a 60,000-square-foot ambulatory care center, an emergency department with 41 treatment bays, trauma department, eight operating rooms, nine labor and delivery rooms, and a two-level cancer center, medical oncology and radiation oncology department.

More Patient Space

The $30.5 million central utility plant was originally slated for traditional stick-built construction. However, the State of Maryland considers stick-built mechanical space as part of the overall building area, which posed a problem with design that would limit medical space in the building. It was a problem the design team determined could be avoided with a pre-fabricated approach to the plant that sits adjacent to the main hospital building and is connected by a corridor on the lowest level.

“By using a pre-fabricated, modular building, the square footage of the central utility plant did not count towards the overall allowable hospital area and allowed for more patient space,” Lamdin said. “It also allowed the plant to be fabricated quicker and installed in time to use its systems for heating and cooling during the final stages of construction, saving the need for temporary systems.”

While the pre-fabricated central utility plant was determined to be “cost neutral” in comparison to a stick-built plant, the time saved by using a modular design ensured that the University would be able to open its doors earlier than originally anticipated.

The final design of the two-story plant required more than 60 modules to create approximately 25,000 square feet of interior space – 18,000 square feet on the first level and 7,000 square feet on the second level.

The plant includes three primary electric utility service feeders, two 2,000-kilowatt emergency diesel generators, and a 2,000-kilowatt natural gas combined heat and power (CHP) generator, which will provide heating hot water to support the year-round heating requirements of the facility.

The CHP has three heat sources: a low temperature loop, a jacket warmer loop and heat recovery off the exhaust flue. The jacket warmer loop will provide 4,700 MBH of heat and the exhaust flue recovery will provide 3,200 MBH to the heating hot water system.

While the system is designed for non-stop operation, control logic was provided for the system to receive real-time utility rates and operate the engine only when beneficial to the owner.

Energy-Efficient Design

The central utility plant and the main mechanical systems were designed with energy efficiency in mind. The CHP generator allows the facility to generate a portion of its own power using natural gas while also producing the base heating load as a by-product of the engine heat dissipation.

In addition, the chilled water plant includes four sets of 550-ton chillers in a counterflow configuration, with one set designated the winter chilled water plant, provided with closed-cell fluid coolers and glycol to allow for winter operation. The other three sets create the summer plant. “The control intent is to operate multiple pairs of chillers to meet the load, which allows the chillers to operate at a very high efficiency,” Lamdin said.

Heat recovered from the CHP will be used as the primary source of heating for the hospital and will be supplemented by the heating hot water plant as required to meet the load. Excess heat will be dissipated via heat exchangers connected to the condenser water system.

The storm water from the main hospital is being collected, treated on site and re-used for cooling tower make-up water.

Continuous collaboration and communication was also critical to the project’s success. The owner, central utility plant manufacturer, design team, general contractor and subcontractors had to work very closely together to make the pre-fab, modular approach work.

As the facility prepares to open, not only is the owner is pleased with the result, but the central utility plant design is already serving as an example of an approach that can accelerate construction of medical facilities without impacting cost or quality.

“We have already used this project and the pre-fab approach as an example of how to efficiently streamline the construction process to save time and possibly cost,” Lamdin said.

Environmental Air Systems Kicks Off 2019

18.01.2019 in News

To begin 2019 with energy and purpose, Environmental Air Systems assembled over 600 employees for a special event held at their headquarters facility.  Factory bays were cleared, a stage was set up, large video screens and American Flags were hung and music was in the air as the lights dimmed for the playing of a patriotic song.

At the end of the song, a lone spotlight shined on their special guest standing on stage, retired Navy Seal Jason Redman.  After describing the intense battle in Iraq that left him nearly dead the spotlight was turned off and after Jason walked off the stage the lights came on to a Marine color guard marching toward the stage.

The American flag was presented by the color guard and the Star-Spangled Banner played to a standing audience.  Brian Evans, EAS President then formally introduced Jason and the two of them asked that all veterans come forward and individually walk across the stage for a small gift and handshakes.  Fifty-six veterans who were in attendance were honored and met our special guest.

Jason Redman then spent the next hour talking through his Five Principles of Elite Performance while relating many of them to his training both as a Navy Seal and an Army Ranger and his over 20 years serving our country in the military.  His Five Principles of Elite Performance are:

  • Teamwork
  • Lead yourself, lead others, lead always
  • Clearly define your mission, tasks & goals
  • Have a relentless overcome all mindset
  • Adapt to the unexpected and to adversity

After Brian made closing comments, everyone had lunch while talking about what they had just learned.  It was a memorable event, and thanks to retired Navy Seal Jason Redman it was an event that many believe will be long remembered.   After lunch a smaller group made up of office and management personnel assembled in the cafeteria for a business update given by each business leader from Construction, Manufacturing, Controls and Service.  They each recognized certain people for their 2018 achievements and reviewed their 2019 business objectives to kick off the new year.

It was clear that Jason Redman made a lasting impression when late that afternoon people were describing a business situation using terminology Jason used in his speech earlier that day.  In Jason’s words: Live greatly, live fearlessly, leave nothing on the table!

Tornado in Greensboro had Wind Speeds of 135 MPH

16.04.2018 in News

This is an aerial photo of Banner Avenue just two lots over from the EAS Banner facility.

A tornado that cut a path of destruction and destroyed homes in Greensboro on Sunday had wind speeds of 135 mph, making it an EF-2 twister.  A line of severe weather spread across North Carolina, bringing heavy rainstorms and two reported tornadoes that toppled trees and ripped apart homes in Greensboro and Reidsville. At least one person was found dead, according to news outlets in the Piedmont.

About 75,000 homes and businesses were without power late Sunday afternoon in the Carolinas. Duke Energy said about 43,000 customers lacked power in North Carolina, and another 9,000 in South Carolina. South Carolina Electric and Gas Company reported 23,000 customers without power in South Carolina.

The city of Greensboro and Guilford County both declared states of emergency. Search and rescue teams went house-to-house in the affected areas, and the Civil Air Patrol conducted an aerial assessment of Guilford and Rockingham counties.

The Environmental Air Systems Banner facility located in east Greensboro while surrounded by severe tornado damage was largely spared receiving a power outage and only minor damage.  Fortunately, the tornado ripped through the area during a time when workers were not present.  An assessment was made by Allen Absher, VP & GM Manufacturing and Robert Alexander, Plant Manager at the site Sunday afternoon shortly after the tornado swept through the area. Nearby homes and businesses all around the EAS Banner facility received significant damage.On Monday and throughout the week EAS workers pulled together and immediately began moving computers and offices into their new Headquarters facility, two weeks prior to its scheduled move.  A number of people worked many extra hours and helped to get offices relocated and up and running with minimal delay.  Payroll had to be run, design had to maintain project schedules and accounting had to remain functioning.

Generators were brought in to get the Banner sheet metal factory back on line to keep up with our backlog and customer needs as hundreds of field workers were counting on their shipments.  IT, with the support of others worked nearly around the clock to provide the needed computing power, phones and necessary facility access and fire and life safety systems at the relocated facility.

Downed power lines and trees.

It was truly a heroic effort by many EAS team members to quickly assess the situation, make decisions, bypass downed trees and power lines to move the necessary equipment, get things up and running and establish order in another location all in a matter of just a few days.  A number of EAS employees also walked around the nearby Banner neighborhood handing out food and water to the many neighbors in need.  Without such dedication, this never would have happened as seamlessly as it did.  Thank You and a tremendous level of gratitude to everyone at EAS that contributed to this heroic effort. The pride and commitment shown by many is now part of the EAS legacy.
