CKC wins awards from CRSI, ENR for towers

CKC’s structural system design increased the leasable space in Tower 12 in Seattle.

Two Cary Kopczynski & Co. projects won 2018 awards from the Concrete Reinforcing Steel Institute and two won awards in ENR Northwest's best projects competition.

CRSI gave an honors award (multifamily) to Tower 12, a 34-story apartment building at Second Avenue and Virginia Street — named for the Seattle Seahawks 12th Man.

MG2 designed and PCL built Tower 12, which was completed in 2017.

CRSI recognized Tower 12 for design and construction, noting that the team used innovative approaches in the cast-in-place concrete structural system to increase the leasable floor area and make the interior design more flexible.

The seven-story Halcyon Hotel in Denver won an award of merit in CRSI's multifamily/hotel category. It has 155 rooms, restaurants, retail, a rooftop pool, meeting and event space, fitness center and subgrade valet parking.

BMC Investments was the developer, working with JG Johnson Architects and Mortenson Construction. It was completed in 2016.

CKC said the hotel is cast-in-place concrete with post-tensioned slabs. The shear walls and slab-column frame resist wind loads. Full story height transfer beams allowed for open space in the second floor ballroom.

ENR Northwest picked Kinects Tower at 1823 Minor Ave. in Seattle as the best project in the residential/hospitality category.

Three sides of the 41-story apartment tower taper outward as the building rises. As a result, the floor plate on level 39 is approximately 50 percent larger than the floor plate on level eight, creating more rentable space at the top, where rents are highest.

Security Properties was the developer, Bumgardner designed it and Andersen Construction was the contractor.

The 356-unit tower was completed in 2017.

ENR Northwest also gave Tower 12 an award of merit.

Kemper Development Co.'s Lincoln Square expansion in Bellevue won an ENR award of merit in the office/retail/mixed-use category. HKS Architects designed it and GLY Construction built the 2.6-million-square-foot project, which was completed in 2017. It has a 41-story hotel/residential tower and a 31-story office tower above a four-level retail podium, with six levels of subterranean parking.

CKC said the Lincoln Square expansion shows innovative structural design can respond to demanding seismic requirements, and still meet cost and schedule targets.

The Bellevue-based structural engineering firm said the project used steel-fiber reinforced concrete in the concrete shear wall coupling beams. The firm said this is the first major use of this type of material throughout a project as a part of the lateral system in a region that is susceptible to stronger earthquakes.
