The Conco Companies is providing concrete services for The Mark, a new 48-story high-rise tower in Seattle that will consist of 528,000 sq. ft. of Class A+ office space as well as a SLS hotel and spa. Conveniently located in the city’s central business district, the tower will incorporate a wide range of “green” building features. Scheduled for completion in April, 2017, the tower will bring to the area first-class office space that is highly divisible and offers spectacular views. The unique geometric facade provides exterior seismic bracing for structural safety as well as offering column-free floor plates. The Mark is seeking LEED Gold certification.
The 5,000 cubic yard mat foundation pour was completed in June, 2015 and required approximately 500 truckloads of concrete over the course of the day. The project also includes a sub-level parking structure comprised of shotcrete perimeter walls and a concrete elevator core. As of May 2016, Levels 5-11 decks have been poured and the core poured to Level 35. When the elevator core reaches Level 35, the remainder of the building steel will be erected in one continuous phase. The Mark has 9 floors below grade and 44 floors plus the roof above grade.
