Gordon Barbour Elementary School (GBES) was struggling with summertime high humidity levels due to an outdated HVAC system with no reliable means of properly conditioning outdoor ventilation air. To help address these concerns, B&N provided comprehensive mechanical, electrical and structural design with construction administration as part of the GBES Energy Upgrades project.
The scope of work included the demolition of aging heating, ventilation and air conditioning (HVAC) equipment, such as boilers, pumps, chillers, cooling towers and air handling units. The new design included a new variable refrigerant flow (VRF) heat recovery system, dedicated outdoor air systems (DOAS) and a dedicated heat pump split system for the auditorium. Electrical work included verifying service capacity, designing new power distributions for HVAC equipment and installing panelboards. Structural engineering included reinforcing the roof framing system to support the new rooftop HVAC systems.
In addition, the project team designed new ductwork to be routed and coordinated within the framing of a simultaneous owner-led roofing project and completed permit documents for code approval. Construction administration services included shop drawing reviews, coordination with contractors on various design details, Request for Information (RFI) responses and on-site construction inspections to ensure proper installation and adherence to contract documents.
