Project Summary

The Edith Green-Wendell Wyatt (EGWW) Federal Building (OR0043ZZ), located at 1220 SW 3rd Ave, Portland, OR 97205, is an 18-story office building located in Portland’s government district. The building has been extensively renovated and modernized in a project that was funded under the American Recovery and Reinvestment Act (ARRA) of 2009 and completed on May 1, 2013.

This renovation included the replacement of plumbing and mechanical systems. As part of this renovation, random copolymer polypropylene (PP-R) piping was installed for domestic hot and cold water distribution, rainwater collection and recycle, and zone distribution for chilled water and heating hot water systems.

Since March of 2018, a total of ten (10) failures have occurred. Seven (7) failures in the two inch (2”) PP-R domestic hot water primary loop supply main that extends from water heaters in the penthouse to the basement floor. Two (2) subsequent failures have occurred in the one inch (1”) DHW primary loop return and one (1) weld failure in the LTHW hydronic loop.  This primary loop serves all of the domestic hot water circulating sub-mains in the building. The most recent failure occurred in January 2020. The building remains at high risk for catastrophic failure until these projects are completed.

Project 1:

The scope of this project is the removal of the PP-R primary domestic hot water loop and Zone 1 domestic hot water loop and replace with copper piping.

6. Replace Zone 1 water heater and circulation pump,
7. Remove all abandoned piping and equipment,
