Update on 970 Denny

The Conco Companies is providing a wide range of concrete services for 970 Denny, a 40-story apartment building currently under construction in the South Lake Union neighborhood in Seattle, Washington. To date, we recently completed placing the Level 20 deck.

970 Denny Update - The Conco Companies

As of June 16, 2017, core and columns are being placed concurrent with deck (i.e., levels 19-20). We are operating on a five-day deck cycle, with 11 consecutive five-day cycles completed. We anticipate completing Level 40 by mid-November, R1 by Thanksgiving and topping out at R4 the first week of January 2018. Total concrete placed to date is just over 24K.

Along with placing each deck floor, we are concurrently constructing the core and columns with 386 steel fiber-reinforced concrete (SFRC) coupling beams to ensure the utmost safety in the quake-prone area. Our crew is busy executing five-day deck cycles and has already completed 11 consecutive cycles. Maintaining this schedule, we anticipate we will complete Level 40 by mid-November, R1 by Thanksgiving, and topping out the project at R4 by the first week in January, 2018.

The project is being developed by the Holland Partner Group and the general contractor is Holland Construction. The architect, Weber Thompson, describes the mixed-use project as a juxtaposing of a “modern, sleek and sculpted 440’ tall tower with a crisp podium structure that is carefully proportioned to blend with nearby industrial age warehouse structures.” Scheduled for completion by the summer of 2018, the building expects to receive LEED Silver certification.  

Update on Southport on Lake Washington

Another project Conco has been working on in nearby Renton, WA is the Southport on Lake Washington parking structure. This is our biggest Northwest project to date and we have already placed more than 40,000 cubic yards of concrete, which is just a little over half of the total amount of concrete we will use to complete the project.

Update - Southport on Lake Washington - The Conco Companies

We have placed over 40,000cy of concrete, and are just over 50% complete with total yardage poured on this project. To help reduce noise pollution in a residential area, we are using the Putzmeister 14000E high pressure trailer pump.

Furthermore, as the project is in the middle of a residential neighborhood, Conco is using our Putzmeister 14000E high pressure electric pump station to help reduce noise pollution. We are also using the efficient, lightweight Titan #6 pole shores for the high-bay decks. This is only the second project in the Northwest area that has used the Titan system for high shoring conditions. The structure’s design also includes 24-foot tall, single lift, round architectural columns.

We are proud to report that the Southport jobsite has been recognized by both the project owners and the GC for exceptional cleanliness and organization. Conco is also pleased to report that we have implemented our “top down and bottom up” innovative safety procedures that have resulted in a 6-month, injury-free 2017.

Conco’s mission is to be the best supplier of concrete services in the Western United States and to bring expertise, experience and quality to each project. We continue to upgrade and expand facilities to better serve the growing market for public works projects, commercial, parking structures, educational, and other construction development. We serve California, Washington State, Oregon, Colorado and Nevada.
