COMMAND Center concrete temperature and maturity monitoring has lowered budgets and accelerated construction schedules on hundreds of projects. COMMAND Center can also be used for research, testing for specific concrete selection, and many other unique applications. To learn about how some of our customers have implemented COMMAND Center on their projects, read on.
To showcase a few of the projects that have benefited significantly from COMMAND Center, we packed some of them into a very quick video.
Rogers-O’Brien’s focus on client service led them to seek ways to accelerate project schedules while controlling costs. To complete projects faster—and thus save money—they decided to use COMMAND Center to quickly determine when their pours had reached the necessary strength level. Rogers-O’Brien implemented the system on The Whitley, a 16-story, 300,000 square foot mixed-use project in Austin.
Early in the project, Rogers-O’Brien used the COMMAND Center system in tandem with the traditional approach of cylinder breaks to double-check their accuracy. But according to Michael Jackson, Assistant Project Manager for Rogers-O’Brien in Austin, COMMAND Center proved so consistently reliable that, after the first few pours, they were able to greatly reduce the number of cylinders they poured and tested.
Using fewer cylinders reduced laboratory fees and further accelerated the schedule. As Jackson explains, COMMAND Center “takes the guesswork out of it, and the financial responsibility burden off the contractor to specify how many cylinders to pour or test.”
Rogers-O’Brien saw significant time savings by using COMMAND Center to determine when concrete achieved necessary strength and to reduce test cylinders. According to Jackson,
“We saved one day per floor. With 16 floors, we saved 16 days of schedule.”
Jackson also found the COMMAND Center interface easy to learn and use, which is critical for construction teams. As he explains, “If you can use a phone, you can use COMMAND Center.”

COMMAND Center was used to help save millions of dollars and months of time on the McKinney Tower in Dallas. By implementing COMMAND Center, the Beck Group was able to shave four months off the project schedule and reduce the budget by $3 million. Read the complete report.
The Kimbell Art Museum in Fort Worth opened their new addition, the Piano Pavilion, to the public in November 2013. The new building was designed by renowned architect Renzo Piano and built with a unique and refined architectural concrete—a very light gray, cosmetically flawless concrete never before used in the US.
The Beck Group used COMMAND Center to evaluate mixes with supplier TXI and select the right concrete for the museum. They also used temperature profiles to help perfect the concrete’s color and eliminate cosmetic defects. This resulted in the smooth, consistent, and light panels of concrete that form the facade and interior walls of the building. These concrete panels are ideal for displaying works of art—particularly older, delicate master paintings.
COMMAND Center was used to save several days per pour during the construction of a six-story building and two-level parking garage. Maturity data showed the necessary strength to stress post-tensioned cables in 33 hours—much earlier than lab-cured cylinders.
COMMAND Center was used to speed up the opening time of these I-64 pavement patches by accurately estimating the new concrete’s strength. Traffic was shut down overnight to allow construction crews to saw, remove shattered slabs, drill dowels, and place a fast-track concrete mix with embedded COMMAND Center sensors. A maturity curve was created using the data tracked by the sensors, allowing the construction team to estimate the strength in-place and in real-time. The pavement was opened to traffic within a matter of hours—something that wouldn’t have been possible using cylinder testing.
COMMAND Center was used to track mass concrete temperature gradients on SH 45/Loop 1 in Austin, Texas. Here, two sensors were used to determine the gradient between the core and surface of the concrete. Since both maturity data as well as temperature gradients can be automatically recorded by COMMAND Center sensors, no additional sensors were necessary. COMMAND Center helps contractors meet temperature gradient requirements for mass placements.
The Indonesian Institute of Road Engineering (IRE), also known as Pusjatan, used COMMAND Center to develop a maturity specification for concrete pavements. The IRE will perform laboratory tests to establish a strength-maturity relationship for a concrete mix, and then verify the test method with actual field data. Once the test method is verified, it will be adopted into the concrete pavement specifications.
