Thanks to artificial intelligence, Sixense has developed the Novia solution for acoustic events to answer one of the major questions on your worksites: “Is the excessive noise level caused by my on-site work or not?” This solution, based on machine learning technology, allows you to identify whether or not a particular sound emanates from your construction noises or the surrounding urban activity.

Accessible via our Geoscope interface, Nora allows you to reduce the risks of complaints, site stoppages, or even penalties. The Novia function can be activated at any time on all standard monitoring systems and automatically adapted at each phase of the construction.

This gives you a clear and transparent means to justify good noise management on your worksite to your clients and authorities.

If you are facing noise issues on your worksite in a sensitive urban environment, get in touch with our expert Karim Benaguid for more information.

Sissterra, a solution for worksites having an impacting on underground subsoils in restricted environment

Boreholes and other invasive geophysics investigation techniques are not very well adapted and difficult to deploy in restricted environment such as dense urban areas. Having a good visibility of the underground is however always necessary to carry out these works in such spaces.

It’s the reason why our experts developed an innovative geophysics solution, based on seismic without sources and particularly adapted to dense urban areas: Sissterra.
Based on a passive technology, our solution allows to reduce the number of boreholes and avoid active seismic sources. Sissterra passive technique relies on ambient noise recordings in the underground by autonomous geophones, an easy-to-use and easy-to-deploy system on site.

A turnkey and robust solution

An innovation from the academic field and the world of Oil&Gas, Sissterra is a turnkey solution allowing you to have a global visualisation of the underground subsoils. Our experts in geophysics manage the entire data value chain and can advise you from the reflection phase from your geophysics challenges, and this until the risk evaluation, going through acquisition as well. Sissterra is a tool that helps manage risks associated to the underground as it allows to consolidate the geologic model. The global visualisation ahead of the works allow to anticipate the adjustments of the constructive methods to maximise the site productivity.

Whilst tunnelling using traditional method, the geologists usually carry out regular “manuals” cutting face mappings using a combination of field observation and pictures. But this method is not optimised as the pictures are not “at scale” and are often distorted and therefore, not representative of the actual geometry of the cutting face.

The new photogrammetric solution Pika allows a true and instant 3D reconstruction model of the tunnel face.
The geologist simply takes a few pictures of the tunnel face, then drops off the images on the Sixense Mapping beMap online platform. A Few minutes later, an ortho-image, a 3D map, a point cloud and a mesh are all made available through beMap.
All those files are a true representation of the reality, for both the geometry and the texture.

With Pika, the geologist therefore has access to:

• The lithology and/or the mineralized veins, with real appearance, size and thickness
• The location and the orientation of the fractures and cracks
• The 2D-3D visualisation of all successive tunnel faces, one after another
• The exact measurement of size, distance and surface of anything on the models

Precision, time saving, data storage: Pika facilitates geologic follow ups of excavation works.

Pika is a Sixense Mapping solution.
