Project Details

AEI performed this work as a sub-consultant. The scope of work included demolishing approximately 10,498 sq. ft., renovating approximately 43,486 sq. ft. and includes approximately 17,511 sq. ft. of additions. The existing mechanical systems were replaced in their entirety, consisting of hot water boilers and direct expansion type unit ventilators. Mechanical Scope included documentation and evaluation of the existing mechanical, plumbing, and fire protection systems for the existing 64,051 sq. ft. facility. The following system replacements were determined to be most well suited for the renovation:

• The existing oil-fired boiler heating plant is being replaced in its entirety with high efficiency, natural gas-fired condensing boilers.
• The existing rooftop HVAC equipment are being replaced with decentralized Direct Expansion cooling, hot water heating rooftop air handling units.
• The classroom spaces are being served by individual variable air volume terminal units.
• The gym and cafeteria are being served by single zone, variable air volume rooftop units.
• The office/admin suite is being conditioned with a variable refrigerant flow (VRF) system and ventilated with a dedicated outdoor air system (DOAS).

The entire school’s infrastructure systems were replaced to meet State of Maryland requirements. All new power distribution, lighting, lighting controls, fire alarm, security and IT infrastructure was designed throughout the building based on the Counties standards for schools. LED lighting fixtures with local controls for scene control were designed to be intuitive to the end user. All plumbing systems (piping, equipment, fixtures) were replaced in their entirety. The building will now be protected by a wet pipe sprinkler system
