The Conco Companies have continued to extend their reach throughout the Western U.S. Our service areas include the Bay Area, Los Angeles, San Jose, Sacramento, San Francisco, and San Diego, CA; Reno, NV; Seattle, WA; and Denver and Colorado Springs, CO. Our newest office is in Portland, Oregon. Furthermore, we are pleased to report that with a steady uptick in the construction markets of our service areas, all of our regional offices are staying busy.
One example of our growth is in the San Diego area where we are providing services for the Terminal 2 Parking Plaza at the San Diego International Airport. The $128 million project broke ground in September 2016 and is scheduled to be completed mid-2018. The parking structure will offer three floors of approximately 3,000 parking stalls, and as it is within walking distances of Terminal 2, will be convenient parking for travelers.
Another new project out of our San Diego office is the Miramar Water Treatment Plant in the City of San Diego. The plant was originally constructed in 1962 and provides drinking water to an estimated 500,000 customers in the northern section of San Diego. The project includes the replacement of the Clearwells #1 and #2 built in 1959 and 1974 respectively, a new Chlorine Contact Chamber, an adjoining lift station, new maintenance and operation building, and a security guard shack. The estimated $89 million project was started in June 2016 and is expected to be completed by May 2020.
Conco Pumping was also brought in on the Mid-Coast Corridor Transit Project that will extend Trolley service from the Santa Fe Depot in Downtown San Diego to the University City community. Mid-Coast Transit Constructors (MCTC), a fully integrated joint venture of Stacy and Witbeck, Inc. and Skanska-Shimmick-Herzog, is in charge of the light rail project. We are providing concrete pumping services under the direction of Malcolm Drilling, Condo-Johnson and Skanska.
Furthermore, our San Diego crews are working on the Hedionda Lift Station project for the City of Carlsbad. This is the first time in many years that Conco has had the opportunity to work with the general contractor, Pulice Construction, on a water project. Other improvements in the project include the installation of an estimated two miles of new sewer pipeline. Please visit our website to learn more about Conco’s wide scope of projects.
As one of the nation’s leading commercial concrete contractors, Conco offers a wide range of premium concrete services and products. Our large portfolio includes challenging projects both big and small including several of recent notable projects on the West Coast. Conco proudly serves California, Washington State, Oregon, Colorado and Nevada.
At The Conco Companies, we have a long history of adopting the latest concrete technologies as well as purchasing the latest state-of-the-art equipment to provide our customers with the best range of options for their project. One of the types of pumps that we find are very beneficial in projects with challenging placement specifications is our articulating boom pumps.
Also known as roll-and-fold or Z-fold, articulating boom pumps are available in four-section multi-Z booms or five-section Z-Fold booms and provide us with lots of versatility and a large working range. The pump is it a good choice for hard-to-reach areas or when you need the ease of their maneuverability. In addition to providing a good vertical reach, articulating booms are very easy to transport as they fold into a compact size.
At all of our pumping locations, we have a Putzmeister 28Z, which is the perfect example of the versatility of a four-section Multi-Z boom. Its compact size and great flexibility makes it a great choice for congested job sites. Features include the smallest front outrigger footprint of all models in its class, a smooth concrete flow, and a vertical reach of 89 feet 7 inches. Also since the 28Z does not need a large vertical clearance to unfold, it can be set up and used inside of a building.
The versatility of the multi-Z’s configuration does not require the boom to be fully extended in order to pump; and as the longer, straighter pipe allows for a less stressful concrete flow, it can result in better wear on parts. The Putzmeister 28Z is also adaptable to a variety of material. Please visit our website to see our full list of concrete pumps and Telebelts that are available at each of our Southern California, Northern California and Washington State locations.
The Conco Companies are a leading supplier of concrete services for the Western U.S. and 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 currently serve California, Washington, Oregon, Nevada and Colorado.
The Conco Companies’ Martinez facility was recently honored as a recipient of the Central Contra Costa Sanitary District’s Pollution Prevention Award. All private businesses and organizations located within the Central San’s service area are eligible to enter the annual event. Award recipients are recognized for going above and beyond in their business practices in regard to pollution prevention and environmental protection.
The steps the Martinez facility took that helped them to receive the award include using recycled water to wash their trucks. The facility is also pretreating the water before it enters into the storm drain with an innovative sand-oil interceptor and has installed a new sawdust collector. Another thing the facility has done is to install solar panels and made the change to LED lights to help reduce the amount of electricity they are using.
Conco is honored to receive this award as we are committed to reducing the environmental impact of our operations throughout our entire organization, and whenever possible we invest in and implement “green” technologies. We understand that these decisions not only make good business sense but can make a difference in the environment as well as to the health and wellbeing of our workforce, other tradespeople and the general public.

Many people have no idea what a concrete pump is and how it is used. Just as many people are unaware that concrete pump operators are one of the highest paid careers in the construction industry and that the industry is actively recruiting people who may be interested in a career as a concrete pump operator.
Back in October of 2016, the ACPA (American Concrete Pumping Association) implemented the new “Workforce Development Program” that is designed to help members recruit new labor to fill open positions. Representatives of the program as well as members are attending trade shows and job fairs to promote concrete pumping careers. The group is also using using social media as a way to garner more attention. Furthermore, the ACPA has improved their online ACPA Career Center (at ConcretePumpers.com.) to allow members to post job openings and job-seekers to post resumes. Based on the increase in the number of resumes that have been posted over the last year, the Workforce Development Program is working.
In addition ties have been established with several technical schools and programs in order to introduce students to the benefits of a concrete pumping career. One of the relationships forged is with the Heavy Construction Academy in Brentwood, New Hampshire, which runs a 6-week training program. The academy has students from around the country including many vets who are taking advantage of the G.I. bill to fund their training.
The Workforce Develment Program’s newly appointed coordinator is Chay Ibarra who will carry on the work started by one of the program’s developers and its first coordinator, Sidney Andrews. She is working closely with Andrews and the Board to define the program’s goals.
At The Conco Companies, we are continuously seeking experienced carpenters, cement masons, ironworkers, laborers and operating engineers. Please see our website for more details.

Over the last several years, we have experienced a dwindling number of new workers seeking careers in the construction industry. Some think this may be due to young people entering the job market feeling that construction work is not a glamorous or lucrative profession. The problem has come to a head as older, experienced tradespeople retire and not enough people are stepping into the jobs causing a shortage in experienced cement masons, carpenters and ironworkers.
Another area experiencing shortages is in qualified construction truck drivers that haul materials such as steel, aggregates, cement and ready-mixed concrete. In fact we have heard stories from concrete producers about how they have had trucks parked without qualified drivers to drive them. They have also found themselves in the position of running out of raw materials due to the shortage of material haulers. Many in the industry fear that the problem may stem from companies such as Amazon and Walmart that can offer steadier work than the construction industry.
A recent article from the Business Insider says that the shortage of skilled construction workers may slow the hurricane recovery efforts from Harvey. It reports on a survey from the Associated General Contractors of America that even before the hurricane, Texas, which is in the middle of a building boom, was having trouble filling positons as reported by 69% of the contractors.
Another quarterly report from the USG Corporation and the U.S. Chamber of Commerce that surveys contractors to gauge sentiment and measure the health of the industry supports that finding. It discovered that “60% of contractors reported difficulty finding skilled workers in the third quarter of 2017 due to an ongoing skilled labor shortage.” Additionally 91% surveyed said they were somewhat concerned about the skill level of their work force.
The Conco Companies are one of the leading concrete contractors in the Western U.S. and offer a wide range of quality services and products. While we tackle projects both big and small, our experience includes providing the complete concrete package for the Levi’s Stadium along with other notable projects. We serve California, Washington State, Oregon, Colorado and Nevada.
Recently The Conco Companies announced the topping out of the East County Detention Center, a 500,000 SF expansion and replacement to the existing Riverside County Jail. The project’s General Contractor is Clark Construction and the architect is HOK. The $330 million project will add another 1,626 beds to the facility once it is complete.
Since the jail is located in Indio, CA, one of the most challenging aspects to the job was safely dealing with an average temperature of around 100°F and sometimes reaching as high as 120°F. To ensure the safety of all the workers, we had a full-time safety manager on site. Furthermore, all Conco employees as well as our subcontracted employees followed the ACI’s Hot Weather Concreting procedures. Workers were provided with lots of water, rest and shade as well as educated to recognize the signs of heat-related illnesses in themselves or in a co-worker.
Our hard-working crews formed, pumped and placed 55,000 CY on the project, which also includes the construction a 990-stall concrete parking structure adjacent to the new facility. We also used our pumps to pour piles 60’ below ground-level for Becho, another one of our trade partner on the job.
Phase One of the project includes a three-story administration and support building with an extension of the existing below grade tunnel. Phase Two includes a four-story structure consisting of two housing units and mezzanine levels. The entire project is expected to be completed this winter.
To celebrate the topping out of the structure and as a thank you to our crews and their families, we held a Pre-Father’s Day Company picnic at Prado Dam. Over 250 people showed up to enjoy the hotdogs, BBQ, and other treats. Prizes were awarded and games were played by the kids and grownups alike. Please visit Conco’s website to learn more about the various scope of our large portfolio and the range of our professional concrete solutions.
The Conco Companies are a leading supplier of concrete services for the Western U.S and we got our start in the Bay Area in 1959. Our success has come from offering clients the best value on a wide range of concrete services and products and we are now one of the region’s top commercial concrete contractors. We currently serve the areas of Southern and Northern California, Oregon, Washington Colorado, and Nevada.
Over the last several decades, there have been advancements in shotcrete technology and improvements in the equipment that have resulted in a material that is perfectly suited for more and more applications. While shotcrete virtually eliminates the forming process, it still offers the same structural characteristics as traditional cast-in-place walls. This means that projects using shotcrete are typically completed faster, which saves both time and money.
However to ensure you get the best finished product, you need to use a company that is experienced with the process as well as the proper equipment and skilled crews to place it. At The Conco Companies, we are proud to say we have all three – the experience, equipment and skilled nozzlemen - and our portfolio includes successfully completing a diverse range of projects using shotcrete. Common applications include shear walls, retaining walls, and architectural walls to slope pavement and soil nailing as well as sites with extreme operating environments such as hydroelectric plants along with many other uses.
One project we are currently working on is providing shotcrete services for the new I-5NB HOV lane in Tacoma, WA. For this project, we are using a specialty shotcrete technique that involves carving a design on the shot-face of the retaining walls. To increase efficiency, our crews are doing all of the carving from lifts. This project is a perfect example of the cost-efficiency of shotcrete over traditional cast-in-place concrete as it is saving the project an enormous amount of both time and labor costs.
On another new project in Portland, OR, Conco is providing a full range of concrete services including cost-effective shotcrete. The 14th & Glisan is a 16-story, mixed-use building. Among the scope of the job includes using shotcrete on a three-level below grade parking structure. Please visit our website for other shotcrete projects we have posted as well as those using our other services.

Conco Reinforcing has been extremely busy over the last couple of years and our services have been employed on a number of different types of projects. From airports to mixed-use high-rises, public works, highway projects and others, our two fabrication plants and installation crews have remained hard at work.
One recent project from The Conco Companies includes providing a full range of concrete services for the new five-level Midfield Satellite Concourse North and the Baggage Optimization Project (BOP). This will be a large addition to LAX’s Tom Bradley International Terminal (TBIT). Along with providing concrete reinforcement, we are also providing concrete pumping, formwork and shotcrete.
The Conco Companies also recently began work on the new Tacoma Convention Center Hotel in Tacoma, WA. For the $20 million mixed-use development, Conco services will include the concrete reinforcement along with concrete pumping, formwork, shotcrete and finishing. We were selected for the job due to our successful portfolio of big projects as well as our proven ability to handle aggressive deadlines. When finished, the high-rise will be the second tallest building in the city.
Conco Reinforcing has also done a lot of highway work over the last couple of years including the $2,200,000 Highway I80/SR12 Separation Interchange in Cordelia, CA. Working with Viking Construction, the project was started in November 2014 and completed in 2016. Another project was the $6,700,000 Highway 4/I-5 Expansion in Stockton, CA with Brosamer & Wall that was also complete in 2016.
This is just a few of the construction projects up and down the West Coast that have taken advantage of Conco’s premium concrete services. Our large resources and talented pool of employees allow us to successfully take on the most challenging projects.

The strength of concrete can be increased by a number of methods including using a higher grade of cement or a mineral admixture such as ground granulated blast furnace slag (GGBS). It can also be strengthened by using a low water to cement ratio (W/C) as well as by using well-graded angular aggregates.
Adding more cement to the mix or reducing the ratio of water to cement in the cement paste are two of the easiest ways to strengthen concrete. “Every desirable physical property that you can measure will be adversely affected by adding more water,” so explains the Portland Cement Association. The strength of concrete is also influenced by the quality of raw materials, the ratio of coarse/fine aggregate, temperature, relative humidity, compaction of concrete and the curing process.
The quality of the aggregate is recognized by the size, shape, texture and strength of the material and the coarse/fine aggregate ratio will determine the amount of water that is needed. When the amount of fine aggregate is increased in relation to the coarse aggregate, the aggregate surface increases and demands more water. This means the water/cement ratio is increased, which decreases the compressive strength of the concrete.
The cement used in the mix should be stored under dry conditions and be manufactured using the most appropriate standards. Even the purity of the water used in the mix can have an effect on the strength of the concrete. Another factor that impacts strength is the compaction of concrete because if there is poor compaction of the plastic concrete; air is entrapped and reduces the strength of the concrete. If concrete contains 10% trapped air, it is estimated that the strength of the concrete can be affected by as much as 30 to 40%.
Furthermore, to allow concrete to reach its maximum strength, concrete contractors take into account the air temperature, relative humidity and wind speeds at the time the concrete is poured and in the early curing period. Higher temperatures allow concrete to gain strength more quickly but the final strength is actually lower when hydration occurs at too fast of pace. It also sets up the danger of shrinkage and cracking. Newly placed concrete may be periodically ponded, sprayed, or misted with water or a membrane-forming curing compound or covered with curing sheets.

While there are many applications in which lightweight concrete is the most appropriate choice so are there as many that require heavyweight concrete. Lightweight structural concrete is made using lightweight coarse aggregate and/or lightweight fine aggregate. It typically has a density of approximately 105 pounds per cubic foot as compared to that of normal concrete mixes that have a density of 150 pounds per cubic foot. A common use for lightweight concrete is to reduce the overall load or weight of an entire concrete structure such as on bridge decks, beams, slabs and walls of concrete structures.
Heavy natural aggregates or manufactured aggregates such as iron or lead shot are used to manufacture heavy concrete and offers a density in the range of 270 pounds per cubic foot. There are a number of applications where heavyweight concrete is used including underground garages, as counterweights, radiation shielding in medical or nuclear facilities, and offshore for ballasting in pipelines.
Recently another reason for using heavyweight concrete is being implemented by the Crossrail track slab construction project in London, UK. The contractors are using a dense, heavyweight concrete as a sound barrier and to mitigate vibrations across a certain part of the track slab that runs underneath a business section near the Bond Street station. This particular section of track includes several recording studios that rest above it that do not wish to have any sound interfere with their work.
The concrete mixture took 12 months to develop and included laboratory and plant trials. The end product contains “MagnaDense, which is an aggregate that is around twice as dense as normal aggregate.” Develop by LKAB Minerals, the natural aggregate is “manufactured from the iron oxide Magnetiteis and is formed of black ferrimagnetic natural iron oxide (Magnetite).”
