About this file
This is a mechanical plan document for the Putnam High School Chiller Replacement project located in Milwaukie, Oregon, prepared by System Design Consultants Inc. for the North Clackamas School District. The document provides detailed specifications for the demolition of existing mechanical equipment and the installation of new high-efficiency heating and cooling systems. The project scope includes demolition of an existing air-cooled chiller, associated chilled water and heating water pumps, and concrete housekeeping pads, with replacement of these systems using new air-cooled, high-efficiency equipment that maintains the same or smaller footprint as the existing chiller. New equipment includes base-mounted chilled water and heating water pumps with variable frequency drives (VFDs), an inline heating water pump with VFD, and new chilled water supply and return piping from the chiller to the point of connection. All work must comply with the 2021 Oregon Mechanical Specialty Code, 2019 Oregon Energy Efficiency Specialty Code (ASHRAE 90.1-2019), and 2021 Oregon Energy Code requirements for insulation and structural bracing.
The plan document establishes technical requirements for equipment installation, including provision of structural bracing, maintenance of required service access areas, and integration of new pumps into the existing direct digital control (DDC) system. The mechanical floor plan includes two detailed views—one showing the existing system configuration and one depicting the proposed new work layout in the boiler room (G31) and adjacent areas. The document references additional technical details contained on sheets M0.1 and M0.2, including equipment schedules and control diagrams. The plan is dated December 24, 2024, and was designed by JF and checked by SDC, with coordination required with North Clackamas School District regarding potential reuse of existing VFD components. No pricing, contract term, or response deadline information is contained within this technical specification document.
