Ron Willey // Project Experience

Dental Clinic Renovation – Greater New Bedford Community Health

Ron was the Mechanical engineer for the renovation of existing dental exam and operatories and the expansion for new exam rooms. The renovation was to expand the current dental suite to provide additional exam rooms for a growing patient base. Clinical spaces included clean and soiled utility rooms, exam rooms, training rooms and student shared offices. Existing HVAC and plumbing systems systems were reconfigured to meet the new program space.

Cleanroom Conversion – Confidential Client

Serving as the Mechanical engineer for the fit out of an existing 9000 square foot shell space to be converted into a cleanroom, Ron was responsible for the mechanical design sizing and selection of a make-up air unit, air-cooled chiller, sensible cooling coils to account for space loads, gas-fired humidifier, and pumps with piping specialties. The cleanroom area included ISO 7 and ISO 8 clean spaces that had both positive and negative pressure requirements to adjacent rooms. The plumbing design included a reverse osmosis system and process piping for multiple process gas systems.


York County Community College Addition – Sanford Maine Campus

Ron was the mechanical engineer for the 10,000 sq ft addition to an existing building. The new addition included a welding classroom, pipe fitting classroom, virtual welding classroom, and two teaching classrooms. The design included a dust collection system, ventilation and exhaust systems for the welding classroom. The remaining classrooms were designed to have a variable refrigerant volume system and dedicated outside air unit. Plumbing included restrooms connected to the existing building plumbing infrastructure and specialty gas piping for the welding lab.


Steam Boiler Plant Replacement – Pratt and Whitney

As mechanical engineer for the replacement of the boiler plant at Pratt and Whitney, Ron’s responsibility was to design the piping layout and pipe sizing. The design also included selection of the steam and condensate specialties. The boiler plant consisted of two new 400 HP boilers, surge tank, and deaerator.


Acute Care (COVID-19) Facility – Westchester County

During the COVID-19 Pandemic, Ron was the mechanical engineer for the transformation of the Westchester County Center and its adjacent parking area into an Emergency Medical Treatment facility for 110 patients suffering from COVID-19. Ron designed all necessary HVAC and exhaust needed to provide negative air pressure to the treatment rooms. Inside the facility, four Treatment Pods or wings were installed on the arena basketball court. All Pods were fitted out with necessary clinical spaces such as a Nurses Station, Med Room, Nourishment Area, Nurses Lounge, and storage for linen. Four additional pods with all the above spaces were installed in tents in the arena parking area. Each of the four tents could provide treatment space for 14 patients, bringing the total patient count to 110.


Ambulatory Surgical Care – Signature Health Brockton

Ron was the mechanical engineer for the renovation of an existing imaging suite inside the hospital into an outpatient surgical care center. The new program for the space included pre- and post-operatory areas, two operating rooms, waiting area, and other support spaces. The design included a new air handler to serve the two operating rooms and an existing packaged rooftop unit was replaced with a new unit to serve the pre- and post-operatory areas and support spaces. Cooling redundancy was provided in the operating room air handler by providing a chilled water coil that was fed from the central chiller plant and a DX refrigerant coil fed from a new condensing unit. Humidification was provided using steam from the central boiler plant. Medical gases and vacuum were designed and connected to existing services.

Greene County Jail

As mechanical engineer for a new county jail for men and women in Coxsackie, New York, Ron’s design utilized a vacuum sanitary vacuum system to minimize water usage and allow the facility to isolate nuisance flushing and reduce damage or downtime to clear lines. The HVAC systems included central boiler plant and chiller plant that served all air handlers and terminal units and housing pod units incorporated energy recovery in the exhaust air stream from the cells.


New Hampshire Correctional Facility for Women

Boasting a campus-type layout, the new women’s correctional facility in Nashua, New Hampshire housed 220+ beds and is equipped with a re-entry building and main building and included teaching classrooms and an extensive health care unit. Ron was responsible for the mechanical design which consisted of: a central boiler plant utilizing condensing boilers with low supply water temperature to obtain the highest efficiency possible; housing pod ventilation units with energy recovery and smoke management modes of operation; and the healthcare area was separated into overnight patient care, constant observation, and acute care areas each requiring different types of HVAC specialties.


St. Mary’s Regional Medical Center - Cardiac Care HVAC Upgrade

Ron was the mechanical engineer assigned to design the addition of cooling and ventilation to the Cardiac Care Unit of the main hospital. The project included a VRF heat pump system with two dedicated outside air units. The low floor to floor height presented challenges that were solved with careful coordination and collaboration with the client.


St. Mary’s Regional Medical Center - Partial Hospitalization Program Renovation

Ron was the mechanical engineer assigned to design the HVAC and plumbing upgrades for the renovation of a shell space that will house the partial hospitalization program in the B-Wing. The project included a VRF heat pump system and a dedicated outside air unit.
