CKC Structural Engineers

CKC was proud to support this year’s All In For Autism 5K Run/Walk in Bellevue, organized by the Bellevue Breakfast Rotary Club. This impactful community event draws thousands of participants each year, raising awareness and critical funding to support children with autism and their families. Proceeds benefit autism-focused programs, helping expand access to essential services and resources. With a 5K run, kids run, and family-friendly activities, the event is a powerful example of the community coming together around a meaningful cause. As a Bellevue-based firm, we value opportunities to give back to the community we’re part of, both in and outside of the built environment. We’re proud to stand alongside other local organizations in support of this fun and important event. #CKCStructuralEngineers #AllInForAutism #Bellevue

Construction is moving forward at a new 372,000 SF data center in Chicago (ORD2) for which CKC provided all structural engineering. Foundations are complete, perimeter wall panels are up, and steel erection is underway. This 72 MW facility will include 12 data halls and an administrative wing. Key structural features include: 🚧 Precast concrete wall panels at the perimeter for wind and seismic resistance, using carefully crafted mixes to optimize performance and reduce embodied carbon 🚧 Structural steel framing for interior and roof, optimized for efficiency and constructability 🚧 Cast-in-place concrete generator yards Our team engaged a wind consultant to perform a study on multi-row rooftop equipment configurations to understand how equipment spacing and positioning influences shielding effects. By combining ASCE 7-22 with wind tunnel research on blunt body aerodynamics, wind load reduction factors were determined for variable gap distances, which provided a more efficient design for the wind force resisting system and roof diaphragm. CKC is collaborating with MG2 Design and Edged to deliver a high-performance, resilient data center, building on proven strategies for efficiency and reliability. #StructuralEngineering #DataCenters #ConstructionUpdate #CKCStructuralEngineers

Sloane (616 Battery) continues its climb in downtown Seattle’s Denny Triangle. It’s now on Level 40, with Level 45 topping out right around the corner! Once complete, Sloane will bring 442 new homes to one of Seattle’s most vibrant urban neighborhoods, offering sweeping views of the Space Needle, Elliott Bay, and South Lake Union. The tower features a performance-based seismic system with concrete shear walls wrapping the core and steel fiber reinforced coupling beams at openings, paired with 8-inch post-tensioned concrete slabs. The variable thickness foundation mat -- 6 feet at the perimeter and 11 feet at the center -- incorporates 100 KSI reinforcing steel, which reduced congestion and improved efficiency. It was designed to support both gravity and lateral loads, while meeting strict settlement criteria. CKC is proud to have provided all structural engineering for this iconic project and excited to see it soon become a proud addition to the Seattle skyline. Thank you and congratulations to our partners Holland Partner Group, Weber Thompson, and the entire project team. #CKCStructuralEngineers #StructuralEngineering #Seattle #Development

Significant progress continues at the Charleston International Airport Parking Garage (PG-3), a 7,200-stall structure and one of the largest parking structure developments in the country. Key recent milestones include: ✅Quad D is now complete, marking another major step forward 🚧Three slab pours have been completed on Level 2 of Quad C, with vertical progress continuing to accelerate 🏗️Formwork has begun for pile caps and grade beams at the Quad A Jockey Ramp, advancing early-stage foundation work 🧩Precast installation on Helix A is complete, with work now progressing on Quad B PG-3 remains a major undertaking, delivering a 2.4M SF, six-story parking structure designed to support both public parking and consolidated rental car operations. The facility will also feature direct airport access through a network of pedestrian bridges, improving overall passenger flow and connectivity. The structural system incorporates long-span cast-in-place concrete combined with post-tensioned beams and slabs, providing the durability and efficiency required for a facility of this scale. Since Charleston is in a pocket of high seismicity, seismic design is addressed through ductile concrete moment frames integrated throughout all quads. Baker Construction Michael M.

Two weeks ago, our CEO Cary Kopczynski and Senior Principals Joe Ferzli, P.E. S.E. and Matthew Hopper, SE, PE attended the American Concrete Institute Convention in Chicago, which set an all-time attendance record and brought together nearly 2,300 concrete industry leaders from across the globe. During the convention, PRO: An ACI Center of Excellence for Advancing Productivity sponsored a session, “PRO: Designer Tips to Unlock Productivity Potential of Advanced Formwork Systems.” Speakers from major formwork suppliers shared design tips and project examples across a range of systems, reinforcing how project productivity can be significantly improved when concrete formwork is considered early in design. To enhance designer understanding of formwork and other key construction activities, PRO recently released the well-received Constructability Blueprint (CB), which outlines strategies engineers and others can use to enhance field productivity by improving the constructability of design. The CB will be periodically updated to reflect industry advancements and best practices. PRO also recently released a Success Story featuring The Ayer, a dramatic new 45-story Seattle tower for which CKC provided all structural engineering. The project’s success demonstrates how the principles PRO is promoting can be successfully applied. The Ayer was recently chosen as Outstanding Multifamily Project of the Year by NCSEA and was a High-Rise category Finalist in last year’s international ACI competition. CKC is a PRO Gold Sponsor and strong advocate for its mission of advancing constructability, strengthening collaboration, and pursuing other productivity enhancing initiatives to drive better project outcomes. https://lnkd.in/g5ha5Z-Z

As Seattle House approaches completion later this year, let’s look at how this landmark project has taken shape, from early construction to a defining presence on the skyline. As Seattle’s largest ever multi-family development at 1.3 million square feet, the project includes two 46-story towers over a 13-level podium and eight levels of subterranean parking, delivering over 1,100 new residential units to downtown’s fastest-growing neighborhood. Seattle House will also offer extended-stay lodging, retail, and a full suite of amenities including a rooftop glass-bottom pool overlooking the city. CKC’s leading-edge structural design incorporated numerous advanced features: 🧱 High-strength 100 ksi reinforcing in the foundation mat to reduce congestion 🏢 Vertical elements with 14,000 psi concrete at the base   📐 Post-tensioned slabs with perimeter cantilevers up to 13 feet to optimize structural efficiency 📏 Carefully developed column layout to eliminate transfer beams 🌎 Shear wall seismic system with Steel Fiber Reinforced Concrete (SFRC) coupling beams to eliminate all diagonal bars 🧠 Performance-Based Design (PBD) used throughout A huge congratulations to the entire project team.

West Clayton Lane in Denver continues to take shape as construction advances into the next phase. With two levels of below-grade structure now complete, work is actively progressing at Level 1, marking the transition from subterranean to vertical construction. This phase brings added complexity, with Level 1 being constructed in six separate concrete pours. That sequencing will continue through Level 3 where the transition to steel framing begins for the residential tower. The completion of level 1 also marks the start of the Southeast steel office building erection. As the largest redevelopment in Cherry Creek North’s history, the project will ultimately deliver 468,705 square feet of mixed-use space, including 132,000 square feet of retail and restaurant, 59,000 square feet of office, and a central outdoor space designed for gathering and social activities. From below-grade construction to the start of vertical progress, it’s exciting to see this project continue to build momentum. 👉 Fun fact: West Clayton Lane marks CKC’s 14th project in Denver’s Cherry Creek neighborhood. Big thanks to BMC Investments, PCL Construction, Tryba Architects, and the entire project team for their collaboration in this project. #CKCStructuralEngineers #WestClaytonLane #CherryCreekNorth #MixedUseDevelopment #StructuralEngineering #DenverConstruction
