Contract review board approves $195,356.92 change order for River Grove Elementary battery system
Summary
The Lake Oswego contract review board on March 10 authorized Change Order No. 19 to increase Triplett Wellman Inc.'s stipulated-sum contract by $195,356.92 to add a battery backup/microgrid system at River Grove Elementary School.
The Lake Oswego contract review board authorized Change Order No. 19 on March 10, adding $195,356.92 to the Triplett Wellman Inc. stipulated-sum contract for the River Grove Elementary School project.
District staff said the change order covers procurement and installation of a larger-than-anticipated battery backup and microgrid components. "This is not just a battery; there's a lot of parts and pieces to it that all feed into the microgrid of the building," the presenter said, noting that the system can discharge during daytime peak periods to lower energy costs and provide resiliency during outages. (Staff presentation.)
Procedural details: The board took the item as an action item. Director Bills moved to authorize a clerk or deputy clerk to execute Change Order No. 19 increasing the stipulated-sum contract by $195,356.92; Director Hartman seconded the motion. Members present voiced "aye," and the motion passed.
Context and benefits: Staff said the battery procurement had been delayed throughout the project and the district investigated multiple vendors and system configurations. The installed microgrid components are larger than originally contemplated, according to the presentation, and are expected to provide redundancy, emergency power and energy-management benefits by reducing peak-period consumption.
Next steps: District staff will execute the change order and proceed with procurement and installation under the revised contract amount.
