For 75 years HEAPY has COLLABORATED with healthcare systems, architects, and contractors, modernizing facilities and increasing their capacity and PERFORMANCE so they can best serve their patients and staff. The landscape of healthcare has changed so much in 75 years as research has revealed better ways to medically treat patients and technology has driven the ability to heal the sick and wounded.

The need to be flexible and resilient while being sustainable and efficient are more important than ever to adapt to the ever changing treatments and technologies. HEAPY has walked side by side with healthcare systems through the decades, offering INSPIRING solutions to these complex problems, offering the technical expertise and timely response that is needed in the demanding healthcare arena.

The Early Years
The Growth Continues
Starting A New Century

The Early Years


  • From the very early days after WWII, HEAPY brought technical design expertise to medical centers that were either starting new or expanding their campus.
  • Around the same time in 1945 when HEAPY opened its first office, the Hill-Burton Act was announced.  Hill-Burton provided construction grants and loans to communities for the building of healthcare facilities. The construction boom in the healthcare sector provided steady work for HEAPY over the first few decades as the company was established and began to grow.
  • It was these early years that began many long-term client relationships that have continued through the present.
  • The ‘50’s and 60’s brought major projects at Grant Hospital, Mercy Medical Center, Mount Carmel Medical Center and Mount Carmel East. Significant additions also occurred at Wilson Memorial, Good Samaritan Hospitals (both Dayton and Zanesville) and Piqua Memorial.
  • These projects added significant capacity to and modernized healthcare delivery to campuses that were in some cases already 40-50 years old and had little upgrades during the two World Wars and Great Depression.
  • Whether these actual buildings or the healthcare systems they represent, HEAPY continues to provide engineering services to most of these clients today.

The Growth Continues


  • In the mid to late 1970’s HEAPY reorganized into Teams of around 10 designers which consisted of all disciplines in lieu of the previous arrangement of being organized by discipline. This allowed each Team to COLLABORATE better on projects.
  • In the late 1970’s / early 1980’s, HEAPY designed an OR addition for the Cincinnati VA which included one of the first neuro operating rooms. The design required a heavily shielded “cage” to prohibit electronic signals from entering the space. The procedures in the room required reading measurements of very small neurological signals and any interference from outside sources needed to be avoided.
  • In the mid-1980’s, HEAPY designed a new patient tower for the Dayton VA. This was a result of a study of their existing building revealing the difficulty of adding centralized HVAC to replace the 600 window A/C units. This also included a large 69KV substation and campus distribution upgrade to address power needs.
  • When OSU needed help with the first MRI in central Ohio, they knew who to call. The MRI shielding was insufficient and was erasing hard drives in nearby spaces. HEAPY was able to help solve the problem.
  • Starting in the early 1990’s, design production shifted from hand drawings to cad.
  • HEAPY designed the very first PET machine to go into a non-research/academic medical center for Kettering Medical Center.
  • In addition to these specific examples, HEAPY also had major projects at Jewish Hospital, Mount Carmel East, VA Hospitals in both Dayton and Cincinnati, Kettering Medical Center, O’Blenness, Holzer and Clinton Memorial.

Starting A New Century


  • The early 2000’s, we saw an increase in the number and size of projects. There was still strong consistency in our long-term relationships including over 150 projects for Mount Carmel, over 80 projects for Genesis and averaging 2-3 projects a year for Fairfield Medical Center and Mercy Health.
  • HEAPY’s long history of energy optimization and infrastructure work came together in a key project at Mount Carmel West when the hospital needed to upgrade some aged equipment serving the surgery and radiology suites including 16 AHU’s, 2 unit substations and multiple ATS’s. They also needed additional chilled water capacity. HEAPY COLLABORATED with Mount Carmel, the CM and subcontractors through multiple phases to accomplish the goal and improved the Hospitals energy PERFORMANCE by not adding chillers but by identifying a piping problem.  We were able to free up significant capacity by making piping modifications, thus saving both first cost and long-term energy and maintenance costs.
  • The creation of a dedicated Healthcare Practice in 2015 increased HEAPY’s expertise in the finer details of Healthcare design and better organized HEAPY’s colleagues for response to larger, more complicated projects.
  • In the past decade, HEAPY was involved in 4 greenfield hospitals including the completion of Soin Medical Center, Mercy West, Mount Carmel Grove City, and Kettering Troy. Included in this decade were also very large additions to Mount Carmel St. Anns, Genesis Bethesda, Cleveland Clinic Avon, Fairfield Medical Center, Adena Medical Center, 2 additions at Soin Medical Center, Beacon Memorial Children’s, Dayton Children’s along with numerous new cancer centers, medical office buildings and senior living facilities.
  • Recognized as a Top 20 Healthcare Design Firm, the HEAPY Healthcare Practice booked almost 500 projects of varying size and location between 2018 and 2019 and over a couple billion dollars of construction design in the past decade.
  • As HEAPY enters the next decade, our Healthcare Practice consists of 60 colleagues from 5 different regional offices providing INSPIRATION to our many clients across the country.
