The work of blasting the new Stockholm metro is historically extensive. With the Metria Miljökoll cloud service, Region Stockholm keeps track of groundwater levels and ensures that buildings and roads are safe from subsidence and collapse.
The expansion of the Stockholm metro is a historic decision that will result in new lines to Barkarby, Solna and Nacka. The plan is for traffic to start running on the new lines between 2026 and 2030. As the tunnel is below the groundwater level, water leaks into the facility. If not managed properly, this can cause ground settlement, which in turn affects buildings, roads and service lines.
Environmental impact is monitored through control programs for groundwater, among other things, which are controlled by various supervisory authorities. Region Stockholm is required to carry out ongoing environmental measurements throughout the planning and construction phase and, if necessary, when the tunnel is in operation. This involves measuring and monitoring the impact of construction on groundwater levels, subsidence, seepage, infiltration and water chemistry.
To keep track of groundwater levels throughout the life of the tunnels and manage the measurements efficiently, Region Stockholm has procured Metria Miljökoll, which is a cloud service for environmental measurements.
With the support of the cloud service for environmental measurements, Region Stockholm's measurement engineers monitor a number of measurement points and hydrogeologists monitor trends over time. They keep an eye on trends in environmental influences, such as whether groundwater levels in a particular area have increased or decreased.
A key part of the service is creating the reports required for reporting to authorities and property owners. This is done automatically, which streamlines the work as manual steps are removed. Another important part is that the service automatically sends alarms if there is a risk of impact.
Field surveyors are fully supported in recording and reporting the information they measure. A digital map shows the location of the many groundwater observation tubes. The technician measures the depth to the water surface and can then enter the results directly into the service. Recording directly in the field makes it easier for technicians, saving them time and minimizing the risk of mistakes. It also improves the quality of the information.
Did you know that...
...in the new metro, more than 100,000 measurements per year are expected once all construction is underway? Groundwater level, subsidence, seepage, infiltration and water chemistry are examples of the various factors that are monitored.
Metria Environmental Check is a cloud service developed to support the implementation and follow-up of control programs to monitor the environmental impact of infrastructure projects. The service provides support for the entire work process - from collection, follow-up, reporting and reporting to both internal and external stakeholders.
Metria Environmental Check provides a coherent process for implementing a monitoring program and simplifies:
