Board approves full design for Hagan school HVAC upgrades including dehumidification; authorizes bid process
Summary
Board members approved the scope to design a comprehensive HVAC and mechanical replacement project at Hagan Elementary—replacing boilers, adding glycol protection, relocating air handlers and designing classroom fresh‑air systems with optional dehumidification—and authorized administration to bid the work.
District staff and architects presented a multi‑part scope for Hagan Elementary School to address boilers, air handling units and classroom ventilation; the board approved full design including DX dehumidification and authorized administration to go to bid.
Facilities staff described constrained boiler rooms and aging air handling infrastructure that currently occupies significant interior space. Presenters said the existing building originally used an array of residential water heaters and later installed boilers without fully redesigning circulation. That configuration contributed to recurring freeze and burst incidents on long runs; presenters said adding glycol to heat‑distribution loops and replacing distribution pumps are necessary to prevent future freezes.
The proposed scope includes a first bid package to replace two gym boilers and the gym air handling unit (work already in design), plus additional design for hot‑water distribution pumps, glycol protection, a replacement fresh‑air handling unit serving classrooms (with optional DX dehumidification) and a bid alternate to install mini‑split heat‑pump units for classroom and office cooling/heating.
Facilities presenter Mr. Rook and project managers emphasized the tradeoffs and lead times. With DX dehumidification included, the total project estimate rose by about $400,000 compared with the design that omits DX. Board members debated whether to pursue the full design and bid package at once or stage work; several members said doing the full design and bidding together would reduce re‑mobilization and achieve longer‑term resilience.
The board voted to approve the full design scope including DX cooling/dehumidification and authorized administration to solicit bids. The district plans to begin construction shortly after the school year ends and to substantially complete the work by mid‑September, subject to equipment lead times and contractor scheduling.
