17 STORY BUILDING – 420,000 sq.ft.
The contractor experienced a three-week project delay due to low cylinder break results from third-party testing labs. Our real-time monitoring, revealed that the concrete consistently met the specified strength within 10 hours of pouring, contrary to the third-party lab’s findings.
CHALLENGES
The contractor was experiencing low cylinder breaks from third party testing labs. This delayed the project schedule by three weeks. We were brought into the project to track in-place temperature and compressive strength and validate performance of their concrete in real-time.
SOLUTIONS
We deployed 10 sensors per floor and began tracking the concrete’s performance in real time. The contractor realized the concrete was reaching the specified strength within 10 hours after pouring vs. the third party testing lab data indicating that the concrete was not reaching specified strength.
KEY METRICS
By expediting the project timeline, the contractor managed to decrease on-site labor and machinery expenses while successfully returning the project to its original schedule
- 34 Days project acceleration
- $230k Cost reductions
BENEFITS
Accelerated Project Schedule
- Contractor saved two days per pour, the access to real time performance data accelerated the project by 34 days in total.
Operational Efficiencies
- Contractor was able to remove form work within 24 hours and begin post-tensioning operations.
Quality Control Improvements
- The contractor managed verify that the concrete met the required specifications with high accuracy, enabling the project to move forward. This outcome was unattainable using third-party test results, given human error.
