Introduction
In the heart of Washington, D.C., the construction of the 17xM Project — a 334,000 square foot mixed-use development — posed unique challenges and opportunities for innovation. Skanska, one of the world’s largest construction firms, partnered with Sensytec to bring real-time concrete intelligence to a project where schedule, quality, and sustainability all mattered.
Challenges
1. Complex urban construction schedule
A large-scale mixed-use project in downtown D.C. demanded tight coordination between trades, with concrete pour schedules driving the critical path.
2. Sustainability goals
Skanska’s commitment to sustainable building practices required data-driven approaches to reduce material waste and optimize energy use during construction.
Sensytec’s Solution
Sensytec integrated SensyCast wireless sensors into the concrete pours across the project, providing real-time temperature and strength data that allowed Skanska’s general contracting team to make informed decisions about formwork removal, post-tensioning timing, and pour sequencing. The data also supported Skanska’s sustainability reporting with documented evidence of optimized material performance.
Key Results
Conclusion
The Skanska partnership demonstrated that real-time concrete monitoring delivers value at scale on complex urban projects — accelerating schedules, supporting sustainability objectives, and giving project teams the data confidence they need to move faster without increasing risk.
Frequently Asked Questions
What was the Skanska 17xM Project?
The 17xM Project was a 334,000 square foot mixed-use development in downtown Washington, D.C., constructed by Skanska.
How did Sensytec help Skanska on the 17xM Project?
Sensytec sensors embedded in concrete pours provided real-time temperature and strength data, allowing Skanska’s team to make faster decisions about formwork removal, post-tensioning timing, and pour sequencing.
How did concrete monitoring support Skanska’s sustainability goals?
Documented sensor data provided evidence of optimized material performance, supporting Skanska’s sustainability reporting and reducing the need for over-design and material waste.
What kind of concrete sensors did Skanska use?
Skanska used Sensytec wireless concrete monitoring sensors, which track temperature and compressive strength in real time and report data to the SensyHub cloud platform.
