Wheaton redevelopment excavation hits 25', nearby businesses feel vibrations

At last count, the massive excavation underway at the future Montgomery County office building and Town Square near the Wheaton Metro station has reached 25' below street level. People in buildings along Triangle Lane report feeling vibrations during the installation of tie-back anchors 20' below their properties. County officials say they think the problem was the drill bit striking a boulder underground. They have inspected the buildings along Triangle Lane, and say they have found no structural issues resulting from the vibrations so far.

Excavation and the ongoing installation of those tie-backs will continue to be the main activity at the site for now.
