Opened in 1954, Dallas’ Parkland Memorial Hospital has played an important role in American history, most notably as the site where President John F. Kennedy was taken after he was shot by an assassin.
Today, it is one of the largest public hospital systems in the nation, serving more than 1 million patient visits each year. With the regional population expected to double by 2025, however, the existing hospital will soon be replaced by a new $ 1.326 billion Parkland campus that will meet the area’s health care needs well into the future. At 2.1 million square feet, the new hospital is nearly twice the size of its predecessor. The 2.8 million square feet campus will feature an acute care hospital with 38 percent more bed space, as well as a separate outpatient clinic, medical/surgical building, parking structure, logistics building and central utility plant.
Grundfos was the manufacturer chosen to supply the building’s hydronic pumps at Parkland.
The Value of Relationships and Innovative Technologies
Grundfos and its regional distributor McMillan James Equipment Company have a long history with Burns & McDonnell, the engineering firm that designed Parkland hospital’s central utility plant.
Burns & McDonnell specified five 300-horsepower KPs at 8,250 gallons per minute for the condenser water system and another five 250-horsepower KPs at 4,125 gallons per minute for the chilled water system. The KPs maintained efficiency levels of more than 85 percent for the condenser water system and more than 88 percent for the chilled water system.
“Parkland will save energy and money by using our efficient pumps,” said Joel McDonald, Grundfos district sales manager. “Being more efficient is good for everyone, especially the owner.”
The energy savings to the end user was a reason why the engineers chose to specify Grundfos’ PACO brand.
“It is critical for our products to be on the drawings,” McDonald said. “On big projects such as this one, success depends on starting early and reaching out to the engineer.”
Appearing in the specifications gave Grundfos an advantage, but it was still important to win over TDIndustries, the mechanical contractor in charge of construction.
TDIndustries had used PACO product in a number of prior jobs, including Dallas/Fort Worth International Airport Central Utility Plant, the Arizona Cardinals’ University of Phoenix Stadium, the Texas Cowboys’ AT&T Stadium and the Kimbell Art Museum.
“The project manager at TDIndustries considered PACO a good product and, most importantly, he trusted McMillan James’ expertise in selling pumps and supporting after sale,” said Isaac Henson, principal at McMillan James. “The project manager knew I had invested a lot of time in the design. He knew us well enough to know that if he called at 9 p.m., we would answer the phone.”
In total, McMillan James sold $400,000 worth of split case and end-suction PACO pumps for the hospital’s central utility plant, a $74 million state-of-the-art facility that provides essential thermal, electric, water and emergency utilities to the campus buildings. In total, there are five PACO split case pumps for the chilled water system, four for the heating hot water system, five for the condenser water system and two for the heat recovery system, as well as two end suction pumps for the condensate transfer system.
At more than 81,000 square feet, the central utility plant is designed to supply the hospital and surrounding buildings with up to 16,500 tons of cooling, 1,000 tons of heat pump chilling, 230,000 pounds per hour of steam and 20 megawatts of emergency power to support 2.5 million square feet of hospital and medical office buildings, according to Burns & McDonnell. Because Parkland Memorial Hospital plays a critical role in public safety during natural disasters, on-site fuel and water storage in the central utility plant can support critical hospital services for at least 36 hours independent of city utilities. These features ensure that the hospital remains resilient throughout the years to come.
