The $24 million Courtyard by Marriott on the riverfront in Corvallis is a new seven-story building with 176 guest rooms, 136-space parking structure, pool and weight room, restaurant and conference facility.
The Harver Co. was brought on board as a late partner and tasked to construct four stories of the guest room structure over a post-tensioned parking structure.
Immediately, Harver project managers moved forward on designing the panelized structure while simultaneously setting up a new panel fabrication yard that would allow flexibility for changes in design while panels were being constructed.
Despite the overlapping timelines of design, fabrication and construction, the install began seamlessly. The first-floor panels had to be shimmed and leveled perfectly to allow the subsequent floors a completely level foundation. The care taken with the first floor resulted in entirely level floors all the way to the roof.
This ensured proper sequencing for numerous assembly crews and shaved time off the overall build. Another fabrication yard was later constructed on site to build the final floor panels, which were far too large to truck on city roads and highways.
Parts of the cantilevered roof and parapet were also built as panels on the new fabrication tables. Harver completed the structure in the first week of December amid ice and snow, almost a month early. This allowed the roofing contractor to begin their phases ahead of schedule.
Ultimately, the exterior and interior framing, drywall and acoustical ceilings all met schedule despite many post-structure setbacks and changes.
Judge’s comment: “The project highlights how the use of off-site pre-fabricated panels can help meet and beat tight construction timelines, allowing craftsmen on site time for framing some of the more complex architectural elements and details.”
