The northeast boundary tunnel project (NEBT) is a reinforced concrete sewer tunnel (7m diameter, 15-48m deep), that will increase the capacity of the existing sewer system in Washington DC’s North East District.

Maxwell GeoSystems is providing its industry leading MissionS cloud-data platform, to meet the client’s needs for real-time feedback of ground deformation in conjunction with shaft construction & key TBM operation parameters.

Due to the sensitivity of surrounding infrastructure, the client relies on MissionOS ’s real-time alarm notification system to alert key parties of potential unwanted settlements.

Addtional key features implemented on this job include proximity functions to relate ground deformation to TBM operations, prediction models to estimate final settlement, and TBM parameter alarms.
