The Conco Companies provide a wide range of concrete services including concrete reinforcement for all of your rebar fabrication and installation needs. By owning and operating two large rebar fabrication facilities in California and Washington, we have the capacity to cost-effectively serve our customers’ needs saving them both time and money. Also Conco’s highly skilled crews are trained on the specialized tools used to fabricate, assemble, and install the rebar.
One example of a current job that we are providing a wide range of concrete services for including reinforcement is 970 Denny Way in the South Lake Union neighborhood in Seattle, Washington. Along with the 4,900 cubic yards of concrete we poured to form the 15,300 square foot mat foundation, we also provided the required 1.3 million pounds of rebar. Another recent project that took advantage of Conco Reinforcing’s services was a parking structure for the new Stanford Hospital in Palo Alto, CA. Our crews constructed two levels below grade, one level at grade and two levels above grade to total the approximately 397,359 square feet parking structure. To complete the project, we supplied 4.2 million pounds of reinforcing steel as well as 17,000 cubic yards of concrete and 1,200 cubic yards of shotcrete. The VA Mental Health and Research Center that is currently under construction in Seattle is a prime example of the benefit of using Conco’s full range of concrete services. On this particular project our job duties included concrete pumping, formwork, place and finish and shotcrete services on the 203,000 square foot structure as well as supplying and installing the reinforcement. When you take advantage of Conco’s unique ability to supply rebar and formwork on your next project, it eliminates the need for coordination between different suppliers. It also helps to ensure you meet timelines and stay on budget. 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.

At The Conco Companies, our shotcrete services provide an excellent alternative to traditional cast-in-place walls. Since shotcrete is pneumatically placed, it virtually eliminates the forming process, saving time and money, while still offering the same structural characteristics as traditional concrete methods. It is used for a wide range of applications including retaining walls, shear walls, and architectural walls as well as soil nailing and slope pavement.
An example of a project that Conco provided cost-effective shotcrete solutions for was the Mark, a 48-story high-rise tower in Seattle, WA. The 528,000 sq. ft. building consists of Class A+ office space and the luxurious 189-room SLS Hotel and Spa. In addition to the 5,000 cubic yard mat foundation pour we did that required almost 500 truckloads of concrete, the project included a sub-level parking structure with shotcrete perimeter walls and a concrete elevator core. A few years ago we also served as the General Contractor on a design-build parking structure for the Brio apartment complex in Walnut Creek, CA. The project included the construction of a five-story; cast-in-place parking structure with stalls for 471 vehicles and chargers for electric vehicles. To complete the project we placed 159,028 square feet of concrete, 750,000 lbs. of reinforced steel, and 1,500 cubic yards of shotcrete. Another type of shotcrete project we worked on was the Enfrente Pathway, a 0.6-mile, multi-use trail that provided a critical link to central and south Novato. Soil nails were installed to retain the hillside and we applied sculpted shotcrete as a finish over the walls. Depending on the type of application, a shotcrete mix can be customized with additives or admixtures. For instance when silica fume is added, it reduces permeability, increases the compressive and flexural strength, and offers better resistance to alkali and chemical attacks. To improved pumpability and adhesion in wet-process shotcrete and for freeze-thaw durability, air-entraining admixtures can be added to the shotcrete. To control cracking and improve impact resistance, different fibers are used or accelerators are added to improve placement characteristics in adverse conditions or increase production capabilities.

As one of the leading commercial concrete contractors in the nation, The Conco Companies provide the Western United States with a wide range of concrete services including producing and placing cellular concrete. Also known as foam concrete, cellular concrete provides customers with one of the most productive, cost-effective solutions in a variety of applications.
Our proprietary cellular concrete product is Confoam™, and is a lightweight, low-density fill material that we customize for each specific job. In addition we have the specialized production equipment and experienced crews that know how to expertly place the highly flowable material for optimal results. While lightweight concrete is typically a concrete made with aggregates lighter than typical stone aggregates and has a density + 120 lb. / cu.ft., cellular concrete uses the internal air cell structure instead of an aggregate and exhibits densities from 20 to 90 lb. / cu. ft. Our cement-based slurry contains a high percentage of foam entrained into the plastic mortar and offers a perfect solution for filling challenging voids underneath slabs and tight, unstable trenches. Also Confoam has a fairly low carbon footprint that makes it “greener” than traditional concretes. Another advantage of using Conco’s foam concrete is that it is self-compacting, and thus eliminates the need for mechanical compaction, which means there is no impact on retaining structures or deep foundations. Furthermore, cellular concrete can be produced to be lighter in weight than the site’s compacted base materials or native soils, and as such, provides an inexpensive solution for foundations. This also means there is virtually no settlement as Confoam can be produced to make the combined weight of the new structure less than or equal to the weight of the removed soil. And perhaps most importantly, placing cellular concrete is safer than traditional fill methods as it does not require employees to be placed in the excavation area. Cellular concrete is just one solution The Conco Companies offer customers to help save time and money.

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. We are proud to announce that a project The Conco Companies provided concrete services for has won another award. The LA Federal Courthouse in downtown LA was recently recognized as a “Gold Winner” in the category for Best Sustainable Project by the LA Business Journal‘s Commercial Real Estate Awards. Last year the Courthouse also won the “2016 Outstanding Achievement and Excellence in Concrete Construction” award presented by the Southern California ACI chapter. In addition the project was selected to compete at the national level at the 2017 ACI National Convention.
Referred to as the “Cube” for its unique cantilevered shape, the 631,000 sq. ft. courthouse was designed and built to earn LEED Platinum certification. The general contractor on the $350 million project was Clark Construction and the architect was Skidmore, Owings & Merrill (SOM). The building’s high efficiency systems include a 1,200-ton central utility plant with a 130-ton heat recovery chiller. It also features a 250 KW roof-mounted photovoltaic array of solar panels. A large skylight brings in natural light and the building’s exterior has “pleats” that maximize daylight penetration and minimizes solar thermal gains. The building’s innovative design allows the cubic volume to “float” over the stone base and is considered to be one of the safest structures against bomb threats or earthquakes. The 10-story Courthouse sits on a 3.6-acre site and includes 24 courtrooms and 32 chambers for judges along with jury assembly facilities and offices for U.S. Marshals. SOM describes the Courthouse design as “using traditional architectural elements such as processional steps, grand public spaces, and enduring materials like limestone to achieve a strong civic identity.” The project broke ground in 2013 and judges and staff started moving into their new offices in September, 2016. The Conco Companies are a leading supplier of concrete services for the Western U.S. We got our start 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 have four regional offices serving California, Nevada, Washington, Oregon and Colorado. The Ten Thousand, a luxurious apartment building in Century City that borders Beverly Hills, was recently recognized as a “Gold Winner” in the category of the Best Multi-family Project from the LA Business Journal‘s Commercial Real Estate Awards. The Conco Companies were honored to provide concrete services on the 40-story, 483-foot residential tower, which is quickly becoming one of the area’s iconic architectural landmarks. The developer as well as owner of the $300 million project is Crescent Heights. The architect is Handel Architects and Shamir Shah Design the interior designer. Swinerton Builders is the general contractor.
Handel Architects explains that the modern all-glass structure was inspired by the work of 20th-century modernists. The exterior is composed of four crystalline quadrants and the sloping roofline stands out in sharp contrast to the surrounding flat-roofed buildings. The façade’s multiple panes of glass are slightly angled away from one another to refract sunlight during the day and transform the tower into an illuminated beacon at night. Ten Thousand received LEED Gold certification and creates a sustainable living environment. Offering two and three bedroom residences, each unit has floor-to-ceiling windows and unobstructed site lines that provide panoramic views that span all the way from downtown Los Angeles, to the Hollywood Hills, and the Pacific Ocean. The building’s lobby and residences feature natural finishes such as titanium travertine from Italy, statuary marble, limestone, grained walnut, and cerused oak. The building also has an on-site garage with a discreet private entrance to the building and 75,000 sq. ft. of indoor and outdoor amenities and a house staff of 60 to provide 5-Star hotel-style services. Indoors, residents can enjoy the 75-foot lap pool with underwater speakers, sauna and steam rooms, a massage and spa treatment room, and fitness center. The outdoor area includes a great lawn, sunning pool and spa, tennis court, strolling gardens, chef’s kitchen, a theater with an 84-foot screen and a fire pit as well as a dedicated dog-run lawn.
