Lutherville Personal Physicians

Heating, Ventilating, Air Conditioning, and Plumbing System

The Lutherville Personal Physicians (LPP) project involved a $1,100,000 renovation construction of a 40,000 sq. ft. Health Care Facility for Mercy Medical located at 1734 York Road in Lutherville, Maryland. Mechanical Engineering & Construction Corporation (MEC²) was the mechanical contractor responsible for the plumbing, heating, ventilating, air conditioning, and computer room cooling system. This renovation project included transforming an existing grocer located in a fully-functioning retail district into a state of the art medical diagnostic and treatment facility comprised of an Oncology Suite, Imaging Center, General Exam, Consultation Offices, and a dedicated suite for a Women’s Center.

Construction was an intense coordination process with the owner, medical treatment staff, The Whiting-Turner Contracting Company, and the subcontractors to build a medical facility to provide the latest advances in treatment and diagnostic medicine to the public. The project site required maximum focus on-site cleanliness and safety requirements due to the location in an operating retail area; the project created minimal environmental impacts to the existing area during construction.

The HVAC system serving the LPP facility provides year-round temperature and humidity levels that meets or exceeds all applicable code and industry standards as defined by the American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc. (ASHRAE). The system utilizes (6) high efficient DX packaged, gas-fired, variable speed rooftop units, coupled with series fan-powered terminal units that provide independent and accurate zone control. The VAV system provides for energy efficient system operation. The cooling system rooftop capacities provide approximately 150 tons of cooling for occupant comfort; dedicated computer room air conditioning units were provided for the server cooling demands and for the imaging equipment. The Imaging Center requires dedicated 24/7 year round cooling. We completed this with the use of a Liebert cooling system to accurately maintain proper temperature and humidity requirements.

The plumbing system included a wide variety of plumbing fixtures for use in the treatment and diagnostic areas. The coordination of the underground plumbing system was a constant source of inconsistencies. This building had no existing as-built drawings for the underground plumbing or electrical systems. This created constant challenges in completing the below slab construction. Our work force would continually encounter plumbing and electrical services that may or may not have been active; a strategic plan of investigation with the GC and subcontractors made a difficult situation run smoothly and safely for successful completion.

Challenges to this $1,100,000 mechanical undertaking included the underground plumbing and electrical issues, as stated above, working in an active, occupied retail facility and coordinating the scheduling of construction tasks for successful mechanical system completion without impeding the process of the other subcontractors. Specific challenges included existing rooftop steel coordination for our new rooftop HVAC units. Renovation projects are always challenging with the coordination of the bulk materials storage and coordination with the multiple trades occupying the same building space.

All said, the project was a success and was completed on time and within budget.
