Nu Feinberg Development, Chicago, USA

Key Achievements

•Wireless network of 6 Shape Arrays established around site.
•SAA Data used as part of real-time FE analysis of design curves carried out by NWU.
•Installation completed in difficult site conditions.
•No reportable incidents.

The project

To monitor a sheet piled wall, surrounding buildings and an existing steam tunnel during excavation works as part of the Nu Feinberg development in the heart of downtown Chicago. Site progress was also recorded 24/7 through the use of a live feed site camera located on the roof of a nearby building which took hourly panoramic photographs to create a stunning time-lapse video.

The challenge

The main challenge was installing the Hydrostatic Levelling Cells which were used to monitor an existing steam tunnel. Due to extreme temperatures many measures had to be implemented to ensure the system operated correctly.

The solution

A higher grade of water and air tubing was used in the installation which would not deform under the immense heat which was present inside the tunnel. Regular checks on the data and inspections on site to check for sagging and data anomalies. Great team working.SAA data was used as part of a real-time FE analysis carried out by NWU to optimise the excavation design curves and then relay that information back to QuickView for an updated, live display.

Thanks for all your help on this project – it was a very successful project for HBI and we couldn’t have done it without you.”  Project Manager, Hayward Baker
