Storyline Apartments

Location: Portland

Contractor: Performance Contracting

Architect: SERA

Team: CWallA, HIilti, Scafco Steel Stud Co., Stucco-O Flex International

The Storyline is a 14-story, 147-unit apartment building in downtown Portland. The design aesthetic is modern with unique influences such as white stucco, metal panel, black vinyl windows, glass canopy and an aluminum storefront system. Performance Contracting’s scope was framing, exterior systems, drywall, finishing, expansion joints and window installation.

This project faced several challenges. The original exterior specification was for traditional stucco applied to cement board. But when estimating the project, the manufacturers could not guarantee this method for buildings over four stories because expected wind loads would crack the finish. Performance Contracting worked with the design team to offer something different and found a new structural insulated panel that offered R-value strength, an extended warranty and a perfect medium for the nontraditional three-coat stucco finish.

Once the product was selected, Performance Contracting began manufacturing the panels and submitted drawings to the city. But Performance Contractingwas asked to stop production for six weeks while the city reviewed the new system and issued approval. During the delay, interior framing continued but could not finish because of the lack of an exterior wall to tie into. Window installation was also delayed.

The final panels consisted of framing, structural insulated panel, a scratch coat, a brown coat, and the finish coat. Since the panels were built inside on horizontal tables, the final coat could be applied with a custom screed with a darby for a smooth finish that lacked any hand-applied randomness.

After the delays, Performance Contracting added staff, ran two shifts and offered solutions to keep the project on schedule.

Juror's comment: “An excellent example of how panels can be used to cut time and provide a great look.”
