Garcia, Galuska & DeSousa was established in 1975 as a Civil, Plumbing and Fire Protection Engineering Firm. Throughout the past 30 plus years, the firm has increased in size and services. The firm now offers a full line of engineering services including Civil, Plumbing, Fire Protection, HVAC, Electrical & Technology.

The strength of our firm rests on its commitment to maintaining principal involvement throughout the project from planning through construction.

With our 40 person staff we are large enough to complete significant programs on time but small enough to maintain principal/client involvement.

In addition, our talented and experienced engineers, project managers, principals and support staff demonstrate our determination and commitment to excellence.

Our firm is a SDO certified MBE in the state of Massachusetts.


Concord-Carlisle High School

Garcia, Galuska & DeSousa, Inc. provided Plumbing, Fire Protection, HVAC, Electrical, and Communications design for the new Concord-Carlisle High School.

The scope of the project included the construction of the new 4-story, 236,681 square foot high school and linked 15,500 square foot athletic building on the site of the existing high school. A well-planned phasing schedule allowed for the students to remain in the existing school and begin the 2014-2015 school year at the new facility while demolition of the old school was ongoing.

The project was preceded by a master plan study for the new school which provided conceptual design and options for the new MEP systems. The new school was designed to provide a healthy, energy efficient learning environment and participated in the MA CHPS program for which GGD provided necessary documentation. The base system was designed to exceed the MA Stretch Energy Code and MA CHPS Superior Energy requirements by utilizing innovative and high efficiency electrical, mechanical, and plumbing systems and a high-performance building envelope. Utilizing the MEP products and equipment listed below, the project achieved an annual energy savings of 57.3% over the studied baseline systems.

The new energy efficient electrical systems include lighting controls and occupancy sensors. High efficiency light fixtures were provided for an average of 0.7 Watts per square foot versus 1.2 Watts per square foot required by baseline design fixtures.

New HVAC systems were designed to maximize energy savings while increasing air quality and comfort of the school’s occupants and decreasing equipment noise levels. New 95% efficiency gas-fired condensing boilers, outside air ventilation units with recovery wheels and displacement ventilation diffusers were incorporated to achieve design efficiency goals. The project utilized high water efficiency equipment in order to minimize water consumption and reduce the burden on the public water supply. The plumbing fixtures selected for the project reduce water consumption by greater than 35% beyond a typical code required design. High efficiency fixtures specified for the project include the following:

  • High-efficiency water closets equipped with 1.28 gallon per flush flushometers in lieu of code required 1.6 gallon per flush.
  • Metering lavatory faucets with maximum 0.2 gallons per minute cycle in lieu of code required 0.25 gallons per cycle.
  • Low-flow 1.5 gallon per minute shower heads in lieu of code required 2.5 gallon per minute head.
  • Classroom sinks equipped with 0.5 gallon per minute restricting faucets in lieu of 2.2 gallon per minute restrictors.
  • Architect: OMR Architects, Inc.
  • Construction Cost: $75,000,000
  • Completion Date: April, 2015
