Construction of Cairn Pacific‘s sizable mixed-use development for Prometheus Real Estate Group is moving along in Northwest Portland.

Saltwood, designed by SERA Architects, will be a pair of six-story buildings with ground-floor commercial space topped by five floors of apartments. The project will occupy space on Con-way master-planned property bounded by Northwest 20th and 21st avenues and Northwest Savier and Quimby streets.

General contractor Bremik Construction is working on Saltwood North, where crews recently poured the first post-tensioned concrete deck slab in the below-grade parking area.

Meanwhile, at Saltwood South, general contractor R&H Construction has completed the first of three planned foundation slab pours 鈥� one accounting for 1,200 cubic yards of concrete in one day.

Ground was broken on Saltwood North in August 2019, and then on Saltwood South in October.

鈥淲e’re just the one level below grade,鈥� R&H Construction project manager Mitch Smith said. 鈥淥n the north, obviously they’re two down. We’re one down and then five over one 鈥� the same going up. Schedule-wise, it will be interesting because they started two months before us, but we’ve always planned that we’ll catch them coming up. So we’ll probably start framing at the same time.鈥�

Both buildings will be U-shaped, with a central courtyard opening to the south. Saltwood South will have an overall floor area of roughly 228,000 square feet, with 42,000 additional square feet in the basement, which is slightly larger than the overall building footprint.

Saltwood South’s exterior will feature primarily brick masonry with metal panel accents and a hint of wood.

鈥淔rom what I can tell, in general they are very similar buildings,鈥� Smith said. 鈥淚t’s kind of a prototype that the owners like, with a nice, open courtyard. The courtyard is something that seems to be important to them, and with it they want to bring a lot of character to the building.鈥�

At Saltwood South, ironworkers with R2M2 Rebar & Stressing are laying down the rebar for the building’s foundation slab and the first set of support columns. Meanwhile, carpenters with Marion Construction Co. are preparing formwork as waterproofers with Sawtooth Caulking install vapor barrier on the lagging walls that will serve as a form for the foundation walls.

Also, Konell Construction is performing excavation, and Bear Electric and Tapani Plumbing are preparing in-slab conduit and plumbing assemblies.

A second large foundation slab pour of roughly 1,000 cubic yards is in the works, Smith said.

鈥淭he concrete plants right now can’t get us enough mud during the weekdays to pull off a big pour like that locally, just because there are so many projects going on,鈥� he said. 鈥淎nd it’s only going to get worse. That’s why Bremik did their pours on Saturdays, which is what we have to do as well.鈥�

It’s about how many yards you can get down per hour, he added.

鈥淲hen you have the larger pours, just do the math,鈥� Smith said. 鈥淥n ours you have a 1,200-cubic-yard pour the first one, and if they’re only going to give you 80 yards per hour it’s going to take you 15 hours to physically put the mud down and not even finish it or any of that. So that’s what’s really pushed us to move to Saturday pours.鈥�

The project team is aiming to finish Saltwood South by August 2021.
