Grant High School is located in NE Portland roughly three miles from downtown. The original structure was built in 1923 with major additions in 1927, 1952 and 1956. The overall size of the current renovation was approximately 284,000 GSF with a combination of both new construction and renovation. The existing 1920’s-era Main Building and Old Gymnasium buildings were demolished to structure and completely remodeled. The large addition was built off the west side of the existing main building, and a new gymnasium added onto the south side of the campus. This project was a joint venture with Andersen Construction and Colas Construction. Andersen Construction was in charge of the main building renovation and additions, while Colas ran the construction of the New Arts Building and the New Gym.
The design team wanted to preserve as much of the existing buildings plaster features as possible. WPI was able to utilize both cast in place plaster and GFRG’s to save these beautiful pieces and preserve the historical value. We also installed a number of unique acoustic systems to help manage sound transmission throughout the building. These included perforated gypsum ceilings and K-13 sound isolation spray any various location. In the auditorium, the large historical barrel ceiling was redone with BASWA PHON acoustic sound plaster. The auditorium ceilings turned out to be one of the architectural highlights of the project.
Additionally, our team also performed a variety of paint and coating scopes on the project. Trying to preserve the historical features of the building was an unusual challenge on this project. Crews were required to protect the original murals in the auditorium that were painted in 1923. WPI was proud to be part of the modernization for the historic Grant High School.
