Portland Public Schools
Tubman Middle School

Portland, Oregon

Alliant Systems teamed with Portland Public Schools and Mortenson on an extremely fast track project during the summer of 2018. The project involved a complete HVAC retrofit of an existing 103,000 square foot elementary school in preparation for its conversion into a middle school. Alliant performed all engineering in-house, and this project was designed and constructed within a five month span in preparation for the school re-opening in the fall of 2018.
