The Andy student housing is a high-end student apartment building located near the University of Oregon campus in Eugene. This multifamily residence stands out without overshadowing the surrounding buildings.
The Andy is a five-story, U-shaped complex covering 43,000 square feet, constructed of wood-stick framing and DensGlass sheathing. The building was finished with exterior plaster, textured Hardie board siding and metal panel accents.
Western Partitions faced many difficulties on this project, including the unevenness and inconsistencies of the framing and sheathing. This required substantial lathing depth corrections to create a suitable level surface before installing stucco.
Several areas could not be sheathed while waiting on detail clarification, and these areas had to be worked around without leaving gaps in the finish system. In cooperation with the general contractor and the architect, a new control-joint system was created, which allowed the contractor to complete these areas with no visible evidence.
Western Partitions applied a complete DuPont Tyvek commercial wrap system over sheathing while rough openings were wrapped with DuPont self-adhesive membrane. Installation of the stucco system included metal lath, casings, corners, and control joints followed by BMI 690 premixed plaster applied at 7/8-inch and Sto acrylic finish.
Since the university was operating on an expedited schedule, the contractor had to meet extreme deadlines to allow for occupancy before the new school year began. The crews not only worked extended hours but multiple crews were coordinated within an intricate project flow to “chase” around the building starting with weather barrier, followed by lathing and stucco, and finally Hardie board siding.
This project is an example of how the right system and installer can create superior exterior plaster applications for the enjoyment of the community.
Judge’s comment: “A sharp eye shows the elegant control joints, the tight installation and the consistency of a quality cladding on a five-story building with 43,000 square feet of space. Textured siding and metal-accent panels were integrated into the cladding as well creating further challenges over the already uneven wood framing, but Western Partitions created a new control-joint system to make it all come together.”
