Size & Type of Project - HVAC Retrofit & Modernization
Robert Frost Middle was constructed in 1970 and later expanded. The scope of work for this project was to replace nearly all HVAC equipment and controls in the original part of the school that comprised approximately 120,700 gross framed square feet. All pneumatic controls were also upgraded to DCC and connected to MCPS’s Central Energy Management System. All classroom ventilation via wall louvers was abandoned and replaced with new Dedicated Outdoor Air Systems (DOAS) with heat recovery. The new DOAS system is air cooled DX with gas fired furnaces and built-in heat recovery. The design approach complied with the current 2006 Energy Conservation Code.
MCE Scope of Services
Meyer Consulting Engineers Corporation was the Structural Engineer of Record and under direct contract to the HVAC/MEP Engineer. The upgrades necessitated wall and roof penetrations as well as roof loading analyses for new equipment and design of remedial roof and wall reinforcement, where appropriate. Design work began in July 2009 with an existing condition of structural framing components. The existing conditions were then compared to the framing shown on original drawings. Once existing conditions were confirmed, preparation of structural construction documents began.
Construction was phased over two summers starting in 2010 and completed on time in August 2011 at a cost of $3 Million. Key MCE personnel included Lawrence S. Nagielski, P.E. (Principal-in-Charge/Quality Assurance), Sanjoy Bose, P.E. (Senior Project Structural Engineer/Project Manager) & Charles Fountain (Structural Inspector/Existing Conditions).
