A 41 story luxury hotel/residential tower is being built in Bellevue, Washington that will see one of the largest concrete pours for its foundation in the country. The continuous concrete pour will set the Washington State size record and it will stack up against concrete pours from around the nation in size and scope, too. The pour started on February 28, 2015 during the wee morning hours and took close to 24 hours from start to finish. Let’s look more at this project.
The Bellevue Lincoln Square Expansion has everyone from construction works to architects to engineers working to create a luxury hotel/residential tower that will beautify and revitalize the city of Bellevue. The continuous concrete pour, more than 13,680 yards of concrete, is just the state as the foundation is laid. Combined with rebar, the foundation will house the massive tower.
The tower will stand 47 stories tall and stand at 450 feet tall. This is why the foundation for this building is such a massive project. It has to be able to withstand the force of the building, and stand atop the six story parking garage beneath it. This foundation will anchor the building well into the future.
485,000 square feet of earth was removed from the site before the concrete foundation was poured and three million pounds of rebar was used to anchor. The foundation will help support the structure in the event of high winds and potential seismic activity. This mat-type foundation is meant to utilize high-strength steel for building projects such as this.
During the concrete pour, temperatures will reach 150 degrees during the 24 hour time period to help mix and set the concrete foundation. Five local plants will be continuously running trucks to and from plants to the site for the pour, while seven pumps will be used at once to pour.
The arena that will house National Basketball Association (NBA) team the Sacramento Kings is undergoing concrete pours that will help reinforce the structure and help update it for the future. The concrete pour will occur Friday, February 6, 2015, with others scheduled throughout the month. These concrete pours will make up the barrier of the site at the bottom, with this pour being the second done for the project.
Other projects included this week at the site of the arena focused on installation of vaults for utilities below the concrete pour, along with micro pile-drilling. The new arena broke ground in downtown Sacramento in October 2014. The $477 million project will be available – if on time – for the 2016-2017 basketball season. As of today, the arena is on schedule to open
60 employees, and more than 600 total workers, will help finish the new arena. More than 60 percent of workers on the project are based locally.The Kings’ new arena has been in the making for over two decades, with the team, NBA and city officials fighting for a new place for the team to play. More than 80,000 tons of concrete have been hauled away since the demolition of the grounds around where the new arena will be erected. 4,000 tons of steel have also been part of that clean-up effort.
Formwork, reinforcement, waterproofing and rebar installation have been on-going between concrete pours to ensure the foundation and structure is sound. This state of the art arena will be able to host more than just basketball, which the city is hoping for. Concerts, conventions and other events, potentially even hockey, could be played or hosted at the site in the future.
Many cities focus, fundraise, and fight for new arenas and stadiums for their sports teams much like Sacramento did for the Kings. New stadiums and arenas help get the community excited for their sports teams, which then drives revenue in for the teams and the city. Since many cities rely on this revenue as a way to boost all sorts of improvement and publicly funded projects, these stadiums and arenas help in more ways that just allowing a team to play in the best place possible.
