Environmental Services has constructed a new LEED-certified, sustainable, energy-efficient office and meeting space for the Columbia Boulevard Wastewater Treatment Plant. Visitors to the treatment plant will now stop first in the lobby of the new Columbia Building. The building also has office space for treatment plant engineering staff and meeting space for staff and the public.
Treatment plant engineers used to work in modular office units. The Columbia Building project included building construction, removing the modulars, reconfiguring a parking lot, adding landscaping and installing security fencing. The project also created a new front entry for the Columbia Boulevard Wastewater Treatment Plant.
The 11,500 square foot Columbia Building provides space for 38 staff and several meeting spaces, including a large meeting space for up to 100 people.
The city contracted with the construction firm Skanska for this project. Skanska started work on the $7.7-million project in summer 2012 and completed construction in fall 2013.
The project includes:
- A new landscaped common area
- A new entrance road that replaces the old road to the administration building
- A reconfigured staff parking area
- Formal landscaping in the common area
- Other landscaped areas that reflect the native Columbia Slough landscape.
The City of Portland's Green Building Policy requires this project to incorporate sustainable design practices and to be certified at the LEED Gold level. The Columbia Building included a distinctive ecoroof and stormwater management facilities.
