Parkrose School DistrictIssuing agency·Portand, OR·via the OregonBuys statewide open-bids boardThe Project converts both schools from gas-fired boiler heating to closed-loop geothermal ground-source heat pump systems. The design team is developing a distributed water-source heat pump / ambient loop system in which classroom and zone heat pumps connect to an ambient loop served by a geothermal wellfield.
Pre-Bid Conference: A non-mandatory pre-proposal conference will be held at 10:00 AM on Friday, 11/6/26, beginning at Russell Elementary School
The work includes closed-loop vertical geothermal wellfields at both sites, a distributed water-source heat pump / ambient loop system, ventilation upgrades including conversion of the existing below-slab air tunnels at Shaver Elementary School for dedicated outdoor air and relief, related electrical service and controls work, and commissioning. The CM/GC will provide preconstruction services including evaluating the budget, consulting on construction planning, preparing open-book estimates, developing a geothermal loopfield and subsurface risk plan, and reviewing design documents. During construction, the CM/GC will manage the work, construct the complete loopfield through a geo-exchange contractor, maintain occupied-campus controls, provide quality inspection, establish a change order system, and track and report PCEF workforce and contractor equity participation.
