Video 1 – Conco was responsible for all of the cast-in-place concrete, formwork, rebar, shotcrete and concrete pumping.  The 4,600 cy mat foundation pour began on January 26th at 2:30 AM and was completed by 9:00 PM.  Conco is targeting January 2014 for the topping out of this 42 story project.

Video 2 –  Conco shot a time-lapse video of a full day on our 815 Pine project.  The video was shot from the tower crane and shows the full concrete pour sequence of deck and all the vertical concrete in 1 shift.  It goes quickly, but the order in which they pour is post-tensioned slab outside the core, post-tensioned slab inside the core (they are pouring through trapdoors in the core work deck), core walls, then columns.

The Conco Companies are providing concrete services for the Kinects Tower, a new mixed-use 41-story high-rise currently under construction in the Denny Triangle area of Seattle, WA. The project is being developed by Security Properties, and is designed by Bumgardner, a Seattle based architectural firm. The building has already received at least LEED Silver Certification. Once complete the 500,000 sq. ft. high-rise tower will consist of 356 multi-family units varying from traditional studios to luxury penthouse suites located on the top two floors as well as 4,658 sq. ft. of retail space on the ground level.

Conco’s responsibilities include constructing four levels of below grade parking and five levels above to provide the building with 316 parking stalls. Working 16 hours straight, we recently completed the 6,000 cubic yard concrete pour for the 145’x120’x9′ and just over 500,000 sq. ft. size PT slab that was reinforced with 850,000 lbs. of rebar.

We are proud to report that we received positive feedback from the City of Seattle’s DOT. They have told us this was the best-coordinated and smoothest run mat pour that they can remember. During the course of the project, Conco will place 30,470 cubic yards of concrete, 3,106 tons of rebar and 671,500 l. ft. of PT cable.
