Conco Now: News & Updates | The Conco Companies

We’re excited to share a look at our work on the One Meadow Glen residential project in downtown Millbrae!

Our team provided the structural concrete for this major development delivering over 13,000 cubic yards of concrete and supporting a 418,352 SF building that will soon welcome new residents.

We also want to give a huge shoutout to SBI Builders Inc. for the amazing collaboration on this project. The SBI team went above and beyond, Creating this video recognizing Conco’s incredible work. thank you, SBI Builders Inc!

We especially appreciated these kind words from Mauricio Garcia, Superintendent at SBI Builders:

“I just wanted to take a moment to recognize the incredible work you all do. Especially the effort behind the scenes from the office! From coordination to logistics, keeping the schedule on point, and managing all the details that often go unnoticed, your dedication truly makes the project run smoothly.”

More progress updates to come. We’re proud to help build the future of Millbrae!

Conco Takes Home International Recognition at the ACI Excellence in Concrete Construction Awards!
We’re proud to share that The Ayer in Seattle, WA, a 45-story mixed-use and residential tower earned 2nd Place in the Highrise Category at the 2025 American Concrete Institute’s Excellence in Concrete Construction Awards Gala. This award is particularly special. It’s an international competition, featuring 14 outstanding projects from 6 countries, celebrating the best concrete work around the world. The Ayer represents the innovation, precision, and collaboration that define The Conco Companies. Despite the challenges of a tight downtown site, COVID-era impacts, and a months-long regional concrete strike, our team delivered a structure that now stands as a striking addition to the Seattle skyline.

We’re honored to be recognized among the industry’s best and proud of our team’s commitment to building excellence from the ground up.

We’re excited to share that Gonsalves & Santucci Inc., operating as Conco, has been chosen to implement our cutting-edge ConFoam Cellular Concrete for the Stanford Medicine Sutter Health Cancer Center in Oakland, CA. This innovative solution will replace traditional compacted base rock methods, setting a new standard for efficiency and precision in construction.

Initially, the compacted base rock installation was projected to take 8 days using conventional methods, which involved cumbersome telebelts and dump trucks. These processes were expected to congest the laydown area, causing significant disruptions to other job site activities. With ConFoam, we’re reducing that timeline to just 3 days, streamlining the process and ensuring faster project completion without compromising quality.

The project scope involves filling a 30-inch interstitial space above the mat slab in two lifts. The first lift will be 24 inches, followed by a 6-inch topping lift to achieve the precise slab-on-grade (SOG) elevation. This method guarantees both stability and durability, providing a solid foundation for the structures above.

For areas requiring thickened edges, our team will use hand tools for excavation, completing the task in just 4 hours. This hands-on approach allows us to adapt quickly to the site’s unique conditions while maintaining high standards of craftsmanship.

Our Permeable ConFoam Drain 27 offers a minimum compressive strength of 50 PSI within 28 days, delivering drainage performance similar to clean sand. Additionally, ConFoam is excavatable, providing convenient access to utilities if needed in the future.

One of the key benefits of ConFoam is its exceptional consolidation, even in difficult-to-reach areas, eliminating the need for traditional compaction equipment like bobcats and jumping jacks. This not only protects utility lines but also reduces the risk of damage during construction, ensuring peace of mind throughout the process.

While traditional methods often cause job site congestion, ConFoam equipment has a compact footprint that allows for continuous work with minimal disruption. This results in a more efficient and productive construction site without compromising on safety or quality.

At Conco, we’re not just laying foundations; we’re shaping the future of construction with innovative, sustainable solutions that prioritize both speed and safety. Stay tuned for more updates as we continue to advance the Stanford Medicine Sutter Health Cancer Center project and pave the way for a healthier future!

On October 26, 2023, the ACI So Cal Chapter hosted its prestigious Concrete Awards in Downtown LA, recognizing outstanding achievements in the field. Conco proudly received honors for two remarkable projects: the Mt. SAC Student Center and The Grand.

The Mt. SAC Student Center was specifically acknowledged for its excellence in the Low-Rise Building category. Notably, this project boasts a sophisticated foundation system strategically distributed across various elevations on two different levels. The cantilevered nonisometric roof slab required thousands of Square Feet of shoring to be installed, maintained, and removed. However, once complete, the red roof capping the 18,000 Cubic Yards of concrete was quite iconic for this community college. Designed to provide an inclusive and inviting atmosphere fostering student engagement, the first floor will feature a convenience store and additional study spaces for both individual and group use. Kudos to the entire team, including Tilden Coil, MHP Structural Engineers, CEMEX, and HPI Architects.

Meanwhile, The Grand-LA received accolades for its excellence in the High-Rise category. This ambitious project involved three substantial mat pours, totaling an impressive 25,500 cubic yards of concrete. The cumulative concrete poured thus far stands at a remarkable 83,201 cubic yards, covering foundations, structural slabs, columns, walls, and shotcrete. The mixed-use development includes a 39-story residential tower, a 20-story Equinox Hotel connected by a courtyard, and 176,000 square feet of retail space featuring shops, restaurants, and a movie theater complex. Developed through a public-private partnership and spearheaded by Related Companies, with design by renowned architect Frank Gehry (also responsible for the adjacent Disney Music Hall), The Grand project stands as a testament to collaborative excellence.

Congratulations to the entire team, which includes AECOM, DCI Engineers, Catalina Pacific, and Gehry Partners, LLP.
