Precis Engineering, Inc. has hired mechanical engineer Stanley Orner, PE, LEED AP, as Project Manager and Aileen F. Tang-Zierold as Senior Commissioning Engineer. The new employees started April 25 and May 2, respectively.

Orner has provided project management and engineering design for specialized pharmaceutical and R & D mechanical systems and equipment, including cleanroom HVAC systems, hydronic and steam systems, and “clean” process utility systems. His pharmaceutical engineering work has included new system design and retrofits. He has also written risk assessments and commissioning test protocols for commissioning and qualification of clean utilities, and managed the system commissioning process.

“Stan has a strong background in HVAC system design for pharmaceutical facilities and is well-versed in development of 2D and 3D systems modeling,” said Precis Principal Larry Gadbois, PE. “He is capable of collaborating with clients and interdisciplinary project teammates alike while providing leadership that assures technical design quality, budget, and project schedule.”

Tang-Zierold brings over a decade of experience as a project design application engineer and HVAC systems designer to her role at Precis. She will add her knowledge of building automation design, mechanical and electrical equipment sequences and HVAC specifications to the Precis commissioning team.

“Aileen’s strengths in HVAC system design and building automation are essential qualities for commissioning critical facilities with complex mechanical and electrical systems,” said Gadbois. “Her technical and leadership skills will support Precis clients through the commissioning process of equipment startup, system calibration, and training.”

Orner holds a B.S. in Mechanical Engineering from the Pennsylvania State University, professional engineering registration in Pennsylvania, and LEED accreditation. He is a member of the International Society for Pharmaceutical Engineering (ISPE) and the American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE).

Tang-Zierold holds a Bachelor of Engineering in Mechanical Engineering from Stevens Institute of Technology. She is an associate member of ASHRAE, a lifetime member of Alpha Phi Omega, and an alumni member of Delta Phi Epsilon. She is fluent in Spanish.
