1/4/2024 0 Comments Climate pledge arena![]() ![]() We provided structural and construction engineering services to Populous for renovation of the 800,000-square-foot arena, which opened in time for the NHL's 2021-2022 season. Complicating matters further were the arena's location in a high seismic zone, just two miles from a fault line, and the project's very aggressive schedule. Most notable among these was how to demolish the structure and excavate 680,000 cubic yards of soil to make way for construction of a new world-class below-grade arena, all while temporarily supporting the roof structure above it. The near-total demolition of the structure below the roof presented several complex challenges. Thornton Tomasetti provided structural design and construction engineering for the renovation.īut what makes this project unique? It preserves the 1960s-era building’s iconic 44-million-pound roof structure and the exterior curtain wall. The $930 million renovation and expansion is now Climate Pledge Arena, a new 800,000-square-foot, below-grade venue that will hold more than 17,000 fans for hockey, basketball, concerts and other events, as well as a new parking garage. ![]() We leveraged our architectural metals team to build support structures for installation and completed in-house training to ensure personnel understood the assembly process before setting foot on site.The historic KeyArena, which started out as the Washington State Coliseum for the 1962 Seattle World’s Fair, has undergone a major transformation, becoming home to the NHL’s newest franchise, the Seattle Kraken. To eliminate unnecessary site congestion, McKinstry completed work offsite to maximize the installation phase. When the delivery of materials was delayed, McKinstry collaborated with the general contractor to adjust accordingly so as not to disrupt others’ ability to continue working. McKinstry worked to shift manpower across all three sites to maximize available labor. The project’s rigid schedule coincided with the peak of the Covid-19 pandemic, placing strains on project delivery. Navigating Covid-19 Constraints and Delays Our ability to purchase equipment directly, perform electrical and energy engineering, design and deliver architectural metals, complete installation using our own labor and perform the required commissioning established McKinstry as the most comprehensive, cost-efficient and streamlined partner of choice. McKinstry performed site development, engineering, procurement, installation and commissioning. Together, the combined solar arrays play a key role in the arena’s ability to reach its zero-carbon goal.Ĭost Efficiency through In-House Delivery A multi-site PV strategy was planned across the Alaska Airlines Atrium at Climate Pledge Arena, the First Avenue parking garage and the Kraken Community Iceplex in Northgate. As a dedicated partner in this endeavor, McKinstry worked across design and construction teams to deliver before the first game of the Seattle Kraken’s inaugural season.ĭue to the arena’s location in the highly congested heart of Seattle, solar photovoltaics (PV) were the only feasible renewable energy source that could be reliably deployed. When your name is Climate Pledge Arena and your goal is to be the first carbon-neutral arena in the world, you have embraced innovation in a big way.
