BILCO roof hatches provide unique access at new Maryland hospital

    Architects designing the new Adventist HealthCare White Oak Medical Center in Montgomery County, Maryland, faced a unique construction problem. They turned to The BILCO Company to help solve it.
    
    The $400 million healthcare facility opened last August. The project included a central utility plant that houses mechanical equipment that sits near the hospital. But with space at a premium, the utility plant needed to be constructed within a tight and unusually-shaped geographic footprint. Large generators, boilers, water heaters and other mechanical equipment needed to be installed. They will also need to be replaced at some point in the future.
    
    CallisonRTKL, the Maryland-based architect, designed a solution that allows equipment to be placed and removed through rooftop access. In addition to supplying standard roof hatches for ship stair access, BILCO manufactured four custom-made roof hatches, each 9-feet by 22-feet, to allow workers to access the equipment when they eventually need to be replaced.
    
    “This is the largest roof hatch I’ve been associated with,’’ said Rick Brigham, who led the installation team for Cole Roofing. “The BILCO hatches were the best choice for this job due to their ability to custom fabricate them to meet special size requirements.”
    
    Robb Macdonald of CBG South, the sales representative who recommended the hatches, said CallisonRTKL was impressed by BILCO’s ability to engineer and fabricate the hatches of such a large and unique size.
    
    “They considered the life span expectations of the generators and looked for a way to replace them down the road,’’ Macdonald said. “The site’s slope presented a challenge to the traditional way of removing large equipment through the sides of the building, so rooftop access was the best solution.”
    
    The 16,000 square foot utility plant includes four emergency generators, a cogeneration generator, four chillers, four boilers, 10 hot water heaters, electrical panels and switchgear and a small office for the building manager.
    
    Central utility plants are frequently included in hospital construction. They are adaptable, expandable and allow easy access to replace aging equipment. “Locating all of the generators, chillers, electrical switchgear and hot water heaters separate from the hospital allows more future flexibility for the hospital and removes some of the more hazardous, mechanical, electrical and plumbing equipment from the hospital,’’ said Ryan Dellinger, architect for CallisonRTKL.
    
    BILCO’s roof hatches are equipped with compression spring operators to provide smooth, one-hand operation regardless of size. They also include hold-open arms to lock the covers in the open position to ensure safe egress, and are constructed with corrosion-resistant materials.

    The hospital is a key part of an area that Montgomery County officials refer to as the “Science Gateway.” The area includes the new headquarters for the Food and Drug Administration, mixed-use projects, new public amenities, and the first rapid bus transit system in the state. 
    
    The hospital sits on a 48-acre parcel and the state-of-the-art facility includes 180 patient rooms. It replaces a facility that was more than a century old that was located six miles away.
