The Conco Companies bring vast concrete services experience to the Kinects Tower, a new mixed-use 41-story high-rise under construction in the Denny Triangle area of Seattle, WA.  The project is designed by Bumgardner, a Seattle based architectural firm and developed by Security Properties. Once complete, the 500,000 sq. ft. high-rise tower will consist of 356 multi-family units varying from 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.  The completion is scheduled for 2017.

Conco will be 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 mat pour.  Due to our detailed pre-planning and highly experienced management, the pour was a very routine event, which was exactly the result we wanted.

Furthermore, 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 ft. of PT cable.

Bumgardner explains that the 440 ft. tall tower was designed to serve as a “highly visible gateway to downtown Seattle, and will reconnect the Capitol Hill neighborhood to downtown with a strong street level presence.”  The building’s unique shape of three sides sloping outward means it will have more square footage on the upper levels than below.  In addition the Tower will feature a rooftop swimming pool, lounge and observation deck.


The Conco Companies are a leading supplier of concrete services for the Western U.S. and  was started in the Bay Area in 1959 by offering clients the best value on a wide range of concrete services and products.  Since that time, we have taken a leading role as one of the top concrete contractors in the region. We currently serve California, Washington, Oregon, Nevada and Colorado.


The Conco Companies were awarded the concrete contract for a high-end condominium project that is currently under construction in the heart of Pacific Heights in San Francisco. The LuXe is a 34-unit condominium that is being developed by Belrich Partners, LLC and led by the marketing firm of Pillar Capital. Forum Design, an award-winning architectural firm, designed the building with a clean, but warm, modern aesthetic. The general contractor is Centrix Builders and Dolman Consulting Engineers is the structural engineer. The project broke ground in March, 2014 and is scheduled to be finished by the end of 2015.

Just recently the Topping-Off Ceremony was held on March 20th for the 7-story, 73 foot tall building. Conco’s responsibilities on the project are to provide all of the concrete pumping and reinforcement services for the project. In addition we are constructing two subterranean floors that will contain 49 parking spaces for the condo’s residents.

The LuXe will feature elegant, large floor-to-ceiling windows and spectacular views of the city and the surrounding bay. The luxury condominiums’ interiors will be filled with amenities such as wood paneling and designer finishes. Sales for the units will begin sometime this Spring.

The new condominiums are just a small start to help improve San Francisco’s housing shortage. A recent Zillow report shows that the city has granted only 193 new housing units permits for every new 1,000 residents. Paragon Real Estate also indicates much the same thing in their report. It shows San Francisco has had a population growth of more than 45,000 residents since 2010 but has only built 7,500 new housing units.

On March 13th, the Local 433 Steel and 416 Rebar Ironworkers celebrated the “topping out” of the U.S. Federal Courthouse that is currently under construction in Downtown Los Angeles. The steel erection of the final two levels started in February, and according to Clark Construction, who is providing the design-build services on the project, presented “some of the more complicated assembly requirements.” The Conco Companies are providing various concrete services for the project.

Known as the “Cube” for its unique shape, the $400 million project will be one of the safest buildings in terms of bomb threats or earthquakes with an innovative design that permits the cubic volume to “float” over a stone base. The project broke ground on August 2013 and is scheduled for completion in 2016. Located on a 3.6-acre site, the 10-story courthouse will include 24 courtrooms and 32 chambers for judges as well as housing district judges, jury assembly facilities, and offices for the U.S. Marshals.

The project has already earned a Green Good Design award for Green Architecture in 2014. The nomination was submitted by the building’s architect, Skidmore, Owings & Merrill, LLP (SOM). Designed to earn LEED Platinum certification, SOM included numerous sustainable features such as “a serrated façade that reduces solar heat gain by nearly fifty percent and a sky-lit central courtyard at the structure’s core, which will provide natural light and circulation to the building’s interior spaces.” Furthermore, the courthouse is designed with water and electricity conservation strategies as well as a roof-mounted 400 kilowatt photovoltaic array.

The 630,000 GSF building will also have one level of below-grade parking. In addition seismic design was a part of the structural engineering process because of the building’s location. SOM designed and engineered a state-of-the-art roof truss system to control lateral drifts.

The De La Salle High School STREAM Innovation Center in Concord, California is currently under construction. STREAM stands for Science, Technology, Robotics, Engineering, Arts and Mathematics. When completed, it will be a state-of-the-art integrated complex for the high school students to pursue learning across the sciences and humanities. Construction on the multi-disciplinary building was started in June, 2014 and the Center is scheduled to open August, 2015.


The Conco Companies are providing all of the concrete and reinforcement services for the $20.5 million construction project. The contractor on the 27,288 square foot, 2-story building is Cahill Contractors, Inc., a local Bay Area firm with experience across many markets and types of construction. The architect is Ratcliff Architects, who are recognized for their state of the art campus designs that integrate sustainability as a central element in the design process. The new Center will incorporate both “green” design and construction.  


While this may not be one of Conco’s largest projects, it certainly ranks as one of the most important construction projects that we have had the privilege to be a part of. According to De La Salle H.S., The STREAM Innovation Center will help students prepare for a global job market that will look much different in 10, 20, and 30 years from now. The Center will help them to expand teaching and learning opportunities and allow the school to increase their Robotics course offerings. The state-of-the-art laboratories will improve the integration of technology as well as provide the space to offer more science electives.
