Woodlin Elementary School, Systemic HVAC Study & Retrofit

WAI provided design and integration of the MEP and structural systems for this 60,725 sq. ft. HVAC replacement, and replacement of the Building Management System (BMS). This project initially started in 2005 with a study of the HVAC system, and continued with Phase II in 2007, and Phase III in 2015.  MCPS issued this project in phases, to which WAI responded and completed in a timely manner, meeting all project schedule requirements.

Based upon the recommendations, this project continued to Phase II & Phase III where we:

• Replaced the existing chiller with nominal 120-ton machine. WAI also incorporated a refrigerant detection system, provided a new motor starter, disconnect and other electrical accessories as necessary.  We replaced the existing 15 hp hot/chilled water circulating pumps with equivalent.
• Replaced 16 unit ventilators and 29 fan coil units with equivalent units. Provided connections to the existing run-outs from hydronic piping, wall mounted thermostats and new outdoor air louvers.
• Replaced the existing hot water heater, 199 MBH, 82 gallon, with an equivalent unit.
• Replaced 2 existing sump pumps with equivalent. This included a new motor starter, disconnect and other electrical accessories.
• WAI provided the design for new layout of boiler room piping. This included all hydronic specialties including: 4 gas-fired hot water boilers, air separator, expansion tank, chemical bypass feeder, make-up water system, control valves, change-over-valves.
• WAI provided electrical modifications design of existing service and distribution due to the replacement of mechanical equipment.
