The Lincoln Hall building is part of Portland State University and home to their Performing Arts Programs. Originally built in 1911 as Lincoln High School it is the oldest surviving high school building in Portland, Oregon. The building became part of PSU in 1952. After months of demolition to the existing finishes and structure, upgrades to the building included new offices, classrooms, auditoriums, sound rooms, computer lab, and theater rooms. The project was a Leadership in Energy and Environmental Design (LEED) job achieving LEED Gold certification. To learn more about Lincoln Hall click here.
The Lincoln Hall renovation made much needed upgrades to the old leaking and molding building. Most of the interior plaster that remained was re-coated or replaced. The interior light wells previously closed up were re-opened during this project. In order to access the light wells three stories of scaffold for two light wells were constructed. Construction within the light wells included new seismic bracing upgrades. This work required workers to lower 60 feet long still beams through the openings in the roof. A new sound proof ceiling and acoustical clouds were installed in the basement auditorium allowing the previous storage space above to be used as a public area.
The upgrades to this building included many very unique acoustic related details. Acoustic details were comprised of ceilings, walls, and suspended clouds. Sounds proof walls were constructed with double layer sheetrock on each side and rigid insulation between framing members. Removal of existing molded and wet interior plaster systems and replacement with new was required throughout the entire building. Patching of existing straw walls was required as well. Acoustical ceilings were designed and installed to support mechanical cooling systems to eliminate sound transfer from floor to floor.
