The Marshall Union Manor is a retirement community in Northwest Portland. The project was constructed of 11 stories and 243 units that needed complete redesign and construction of plumbing and occupied repipe. Our team approached this project differently due to the tenants occupying the Manor while our team was diligently working. Our team provided effective communication with tenants and general contractors to ensure residents were not disrupted. The implemented project resulted in significant energy savings and efficiency throughout all facilities on the property including a 70+ year life expectancy with the new installation of the Aquatherm piping systems.
