Every year, the Southern California Contractors Association (SCCA) hosts its annual Safety Awards to recognize the achievements of those in the industry working to create safer, accident-free working environments and job sites. This year’s Safety Awards were held at the Phoenix Club in Anaheim, CA and looked back at all SCCA’s members accomplished in 2018. Los Angeles commercial concrete contractors and other contractors from across the region were in attendance, including The Conco Companies, who walked away with the Zero Accident 2018 award that evening.

Industry leaders: SCCA and Conco Pumping

SCCA is a longstanding membership organization that brings union-affiliated contractors in the construction industry together to foster superior industry standards by encouraging sound business methods, efficiency, and cooperation among contractors. The SCCA accomplishes this by hosting several membership meetings throughout the year and across southern California that provide opportunities for professional development and networking. In addition to these meetings and educational seminars, SCCA also provides legal, labor, and safety resources and advocacy for its members, as well as opportunities to celebrate those who are reaching the high construction industry standards the SCCA is working to promote.

2018 SCCA Zero Accident Award - Conco PumpingThe Safety Awards

TThe SCCA Safety Awards were created to recognize the members who have performed and excelled in accident prevention. SCCA understands the importance of safety within the construction industry, and believes an innovative safety culture, adherence to strict safety practices, and accident-free operations is worth celebrating. At this year’s Safety Awards, the Conco Companies was recognized with the Zero Accidents 2018 award for its stellar record, along with other companies that attained the same laudable accomplishment. Obtaining and maintaining an accident-free record is not an easy feat, as OSHA reports the average rate of recordable incidents within the industry to be multiple incidents per year, per contractor. Conco has worked to mitigate this risk within its own range of concrete services by utilizing a thorough accident prevention program and promoting the vision and initiatives of its safety teams. This combination of diligent safety practices and innovation helped make Conco a worthy candidate for industry recognition at the 2019 Safety Awards.

The Conco Companies’ mission is to be the best supplier of concrete services in the Western U.S. and to bring expertise and incomparable quality to each project. We continue to upgrade and expand our facilities to better serve the growing market for commercial, educational, parking structures, public works projects, and other development.

  • 61-Story Salesforce Tower Distinguished for its Sustainability

CEMEX, a global building materials company, today announced that Conco Companies, has been awarded a prestigious CEMEX Building Award for its work on Salesforce Tower, San Francisco’s tallest building. Salesforce Tower won first place in the Sustainable Building category in the 2018 International Edition of the CEMEX Building Award during a ceremony Thursday, November 8 in Mexico City.

Salesforce Tower, a 1,070-foot skyscraper completed in 2018, required 110,000 cubic yards of ready-mix concrete from CEMEX to complete its foundation and core interior walls. The building’s mat pour was one of the largest in San Francisco’s history, requiring 18 hours to complete.

“Salesforce Tower is probably one of the most challenging projects we have done,” said Joe Sostaric, Conco’s Corporate Vice President. “CEMEX worked very hard with us. We went through multiple trials, including building mockups, so that we had a mix design to meet all the standards, not only to meet the ultimate strength of 10,000 psi, but also making sure it was placed correctly and had the correct characteristics. We’re proud of what we’ve been able to build.”

Salesforce Tower includes state-of-the-art amenities with low environmental impact, designed for LEED Platinum status. The building includes the usage of recycled water and rainwater as well as the incorporation of natural daylight. Recycled materials were also used where possible. In addition, Salesforce Tower’s design includes innovative power-saving features and 100 percent natural air on all floors.

“The CEMEX Building Award recognizes industry leaders, and Conco Companies is a strong example of one,” said Marsat Lal Mirpuri, CEMEX USA’s VP/GM Ready-Mix Bay Area. “We’re proud to have worked with Conco on such an exemplary achievement, reshaping the San Francisco skyline with an iconic project that will stand for years to come.”

The first phase in the renovation of the historic LA Memorial Coliseum won the 2018 category of Outstanding Performance in Repair & Restoration for the Southern California chapter of ACI. The Conco Companies was the concrete contractor on the high profile project and has previously been recognized with ACI awards. The project also included general contractor Hathaway Dinwiddie / AECOM-HuntJV; structural engineer Nabih Youssef; and concrete supplier National Ready Mix.

LA Memorial Coliseum Renovation First Phase

Originally constructed in 1923, the LA Coliseum has become an iconic venue from hosting Super Bowls, the Olympics, and numerous other events. The high-profile renovation is being done to update the Coliseum to host the LA Rams and the Olympics in 2028, with an eight-story modern structure with press boxes and luxury suites as well as new lighting, updated audio, Wi-Fi, and video scoreboards.


The first phase of the renovations required Conco’s experience in precision project planning and execution of complex projects. In this renovation, the construction had to work around the 2018-2019 football seasons of the USC Trojans and LA Rams. Phase 1 included demolition, excavation, shoring, concrete placement, and creating the structural steel frame for the 7-story building. The on-grade seating, which included radiused, sloped seating, required special admixtures to meet the project constraints.

Conco’s mission is to be the best supplier of concrete services in the Western United States and to bring experience, expertise and quality to each project.  We continue to upgrade and expand facilities to better serve the growing market for public works projects, commercial, educational, parking structures, and other construction development. Before you start your next construction project, please contact us to experience the service of one of the top-rated Los Angeles concrete contractors.



The Wilshire Grand Center was recently awarded the Gold Award by the Los Angeles Business Journal for the “Best Mixed Use Project”.

More information about Conco’s role in the Wilshire Grand Center can be found on the following blog posts.

Lifting Los Angeles to New Heights

On Monday, February 29, 2016, the Conco Companies topped off the core of the Wilshire Grand Center building in downtown Los Angeles.  With over 150,000 cubic yards of concrete poured, and an intensely dedicated crew peaking to over 160 men and women on site, the Conco team has finally reached the milestone to lead the way for the interior finishes.    Read more…

Breaking the Guinness World Record for the Largest Continuous Mat Pour

Starting at 4:47 p.m. on Saturday, February 15, 2014, Conco broke the Guinness World Record for the largest continuous mat pour in 18 ½ hours (1 ½ hours under the projected time).  To verify the event, there was an official Guinness World Records adjudicator on-site.  The mat pour was for the new Wilshire Grand Center that is being constructed in downtown Los Angeles and is slated to become the tallest building in the U.S. west of the Mississippi.  Read more…

Conco’s Thermal Control Plan of the Wilshire Grand Mat Foundation Pour Proves Successful

Among the many unique features of the Wilshire Grand mat foundation pour was the thermal control plan.  Occasionally we need to make provisions for the heat that is generated in mat foundations.  In mass concrete structures, there are two thermal properties that must be considered: the maximum temperature and the temperature difference between the center of the structure and surface.  Read more…

Conco’s Equipment Met the Tough Challenges of the Wilshire Grand Pour With Flying Colors

To successfully complete the world’s largest continuous mat pour, one of the biggest challenges Conco faced was to find ways to unload 120 – 150 truckloads of concrete per hour. With the need to unload so many trucks in such a short period of time, Conco’s plan called for thirteen points of placement in the mat foundation.  However, only two sides of the project were accessible from the street.  Read more…

Record Setting Event Accomplished Without Injury

While Conco is justifiably proud of breaking the World record for the largest continuous mat pour, we are even more proud of doing it safely.  Our commitment to safety began with the vision from Conco’s Southern California General Manager, Rick Parker.  Five months prior to the pour, he invited John Messing, Conco’s Safety Director, to participate in the planning meetings for the Grand Pour.  Rick has learned from his years of experience that projects go more smoothly when the safety department is involved early-on to ensure that safety is built into the overall work plan.  Read more…

Conco Awarded the Wilshire Grand Center Project

Conco has been given the opportunity to participate in another landmark project by providing concrete services for the new Wilshire Grand Center being built in downtown L.A.  The new tower will become the tallest building in the United States west of the Mississippi.  This is one of several of our large-scale projects in Los Angeles. Others include the recently completed 125 year old Hall of Justice retrofit, the new Federal Courthouse, a new 45 story cast in place building at 10000 Santa Monica, The iconic ARTIC transportation Center in Anaheim and several smaller projects.  Read more…
