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.

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.

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.

The groundbreaking ceremony for the 418,000 square-foot project was held on September 25, 2014, and it is scheduled for completion in spring of 2017.

In addition to the business-class hotel and apartment units, the project will include a 90-seat restaurant, meeting space and a rooftop garden. The hotel will occupy the first through 11th floors with the residential apartments on floors 12-18. The top floor will offer amenities for the residents and hotel guests including a lounge, clubs, and exercise room. There will be a pool at ground-level.

Washington Place is located within easy walking distance to The Westfield Southcenter mall, entertainment, and a bus transit center. In addition a pedestrian/bicycle bridge is under construction by the city of Tukwila, which will go from Southcenter all the way to the Sounder rail and bus station.

At The Conco Companies, we are one of the leading concrete contractors in the Western U.S. and offer a wide range of quality services and products. Our experience includes providing services for commercial, educational, parking and other construction development as well as public works projects. We serve California, Washington State, Oregon, Colorado and Nevada.

The Conco Companies are providing concrete services for a new office building in downtown San Francisco located at 350 Bush Street. The new 20-story high-rise will have 18 floors of office space, one lobby level, and a roof terrace as well as a two-level subgrade parking structure. In addition as the office tower will incorporate the San Francisco Mining Exchange, a historic landmark, as its primary entrance, the project also includes the “Historic Renovation of San Francisco Mining Exchange Building.”

The client on the project is the Lincoln Property Company and Hathaway Dinwiddie is serving as the general contractor. The project was designed by the architectural firm of Heller Manus Architects and integrates the terra cotta façade and the columns of the landmark building with the office tower. The plan calls for a grand lobby in the historic exchange hall as well as a galleria at the street level. Once complete, the project will include 469,000 square feet of new and renovated space and will be a balance of antique and modern. The building is seeking LEED Platinum certification and will feature a number of environmentally advanced technologies.

The Mining Exchange building was constructed in 1923 and for a short time was used as the Stock Exchange. It was designed by Miller & Pflueger, an architectural firm that designed a number of significant S.F. buildings of the time and closely resembles the New York Stock Exchange that had been constructed twenty years earlier.

Through the years, the building was used for the San Francisco Curb Exchange from 1928-1938, the San Francisco Chamber of Commerce from 1938-1967, and finally the Western Title Insurance from 1967-1979. It has sat empty since 1979.

The new VA Mental Health and Research (MH&R) building currently under construction in Seattle, WA is a prime example of the benefits The Conco Companies bring to a project with our ability to provide a full range of quality concrete solutions. Breaking ground in April, 2015, the 6-story project is being developed by the U.S. Department of Veterans Affairs and is designed by Stantec Architecture, Inc. and The Design Partnership, LLP. The Clark Construction Group is serving as General Contractor. Highlights of the project include energy-efficient systems, two landscaped indoor courtyards, a grass-covered rooftop and a rainwater-harvesting system for irrigation. The building expects to achieve LEED Silver certification to meet federal mandates.

The Conco Companies Veterans Affairs MH&R Project

Conco is providing all of the concrete pumping, formwork and place and finish services for the project as well as supplying the reinforcement. As the project is on an extremely tight timeline, our unique ability to supply both the rebar and formwork eliminates the need for coordination between several different suppliers and enables the work to move forward in an organized manner. Conco’s shotcrete services will be used for nonstructural site walls.

The MH&R building will be comprised of a steel frame with concrete fill on metal decks at all elevated levels, buckling restrained braced frames grounded on shallow spread footings, concrete cast-in-place walls, and green roofs. Since the entire façade is made up of a customized wall system, the project presents a distinct challenge with its need for high cast in place and architectural walls. To facilitate this, extensive off-site performance mock-up testing and on-site visual mock-up testing was performed.

Scheduled for completion in late 2017, the 203,000 square foot building will house more than 250 mental-health staff members and 60 researchers. Officials at the VA state that the new facility will provide the latest treatment services for veterans suffering from post-traumatic stress disorder (PTSD) and other mental-health problems. Furthermore, the campus’ outpatient therapy, clinical research and educational programs will all find a new home at the facility. Designed to create a calm and supportive environment for veterans, the MH&R building will also foster a collaborative, team building approach between the clinical and research staff.

The Conco Companies are a leading supplier of concrete services for the Western United States. We have built a reputation on superior concrete formwork, reinforcing, place and finish, shotcrete and other ancillary services that benefit from our vast experience.
