Since the start of construction phase in late summer of 2020, bridge development has progressed with successful completion of multiple pile driving pier locations along with the start of land embankment operations on both the Maryland and Virginia shores.

In addition to the ongoing bridge instrumentation monitoring, FTG is monitoring land embankment construction using a combination of inclinometers, piezometers, settlement plates, and ground monitoring points.

The land instrumentation data allows the project engineers to evaluate ground movements, pore water pressures, expected settlement, and embankment stability to help control effective fill placements with minimal impact to the adjacent bridge structure. Weekly project team meetings between representatives of the geotechnical instrumentation specialist (FTG), contractor, owner, designers of record, and other participating parties have provided a collaborative setting to ensure quality construction methods are being met while maintaining safe operation of the existing bridge and future performance of the new bridge.

FTG will be monitoring bridge instrumentation daily for the duration of the project and provide consultation on construction activity as each phase continues.

For vested participants of the project team, FTG’s web-based monitoring platform allows users to view all current and historical instrumentation data for each sensor type. The access to real-time data helps deliver real-time decision-making while maintaining project schedules.
