Monitoring for ground movement during construction

Publish Date

Construction crews building the U District Station will be installing two ground settlement monitors on NE 43rd Street this Thursday and Friday, Feb. 20-21.

These underground monitors, called extensometers, will be installed to a depth of about 50 feet below ground near where the future tunnels will be constructed. The monitors will assess ground movements and will notify contractors if construction movement exceeds the allowable limits during tunneling and excavation activities.

A drill rig will be used to bore the hole for monitor installation. The work will be completed between 7 a.m. and 5 p.m.
