Collective waste collection action to preserve the oceans

Sixense teams collected more than 400 kg of waste during the Project Rescue Ocean challenge


At Sixense, environmental commitment is developed on a daily basis and translated into concrete actions. In 2022, our teams took part in a waste collection challenge, organised by our holding company Soletanche Freyssinet and the Project Rescue Ocean association.

We would like to warmly thank all our employees from France, North America, and the Middle East who took part in this challenge.

This challenge was organised for all Soletanche Freyssinet entities throughout 2022. Thank you to the QSE teams for rolling out this initiative.



Focus on the Project Ocean rescue association

The voluntary association organises eco-citizen actions on the beaches but also inland. Its goal is simple: to raise public awareness of the state of the environment, seas and oceans. Project Rescue Ocean is officially labeled by UNESCO World Heritage.

Sixense donations and support to Oregon State University

At Sixense, we believe that collaboration is key for success. It is very important to us to participate and stay involved in what will become the future of engineering and the industry. To that end, Sixense has  made connections with several universities across the United States, including Oregon State University (OSU).

A recent donation of geotechnical instrumentation equipment by the Sixense USA team has been gratefully acknowledged by OSU Civil Engineering Excellence Fund. Sixense indeed contributes to their development and helps young engineers reach their highest potential. Members of the Sixense USA team have also been deeply involved in supporting universities through guest lecturing, seminar as well as collaborative research.

We are proud to be involved in the success story of young future engineers, and we look forward to more opportunities to support the academic community.

New Laboratory Qualification

After 2 years of collaboration, investment, adjustments of our processes and adaptation to EDF’s quality charter, the Technical Operational Unit of EDF granted us a new qualification in the field of chemicophysical analysis.

Applied in November 2020, this qualification recognises our teams’ skills, efficiency and the quality of our analysis:

  • Identifications of suspended materials,
  • Laser granulomety Analyses,
  • Microscopic fiber count
  • MEB* Analysis and chemical analysis to determine the content of various elements.

Those analysis allow EDF to qualify water materials with nuclear power plants wastes and highlight our wish to permanently provide improvements for the services provided.

For more information, please get in touch with


MEB* : (in french) Microscopie Electronique à Balayage, (in english) Scanning Transmission Electron Microscope (STEM)

Greetings from Sixense teams

All the Sixense teams wish you a happy new year! We would like to take this opportunity to thank our customers for their loyalty throughout the past year.

After an atypical year in 2020, we close this chapter on a positive note by sharing with you a quick report of the year, which was nevertheless rich in projects for Sixense.

Follow the highlights of 2020 in the video below from building to underground construction projects, power plant site, bridge digitalisation to the roof of a stadium in the USA.

Monitoring standards

Sixense takes part in writing international monitoring standards

A group of about ten European experts has been working since 2010 on writing international monitoring standards.

Sixense is involved in the project via Martin Beth, director of our Monitoring Division France, by representing France among monitoring specialists from all over Europe, in charge of elaborating European and worldwide standards (CEN and ISO).

Their aim is to help sharing best practices in monitoring, by coordinating and writing them collectively.


Our expert explains :

Each standard takes between 2 and 3 years work in average and we will prepare about ten of them in the following years. The basic standard on general rules was published in 2015, followed by the standards on extensometers, inclinometers, piezometers and pore pressure cells. Our group is currently working on standards for liquid level settlement sensors, strain gauges and load cells and will start working shortly on geodetic monitoring instruments (automatic theodolites for example).

Sixense Mapping’s partnership with Topcon Positioning Group for Africa

Sixense Mapping’s partnership with Topcon positioning Group to expand in africa          


As a reference in 3D digitisation of existing assets, Sixense Mapping signs today a partnership with Topcon positioning Group to develop their activity in Africa. The common ambition is to fulfil the needs for digital transformation in the African markets of construction, infrastructures, mines and agriculture.


As an international Group, Topcon is a reference in technologic solutions for constructions such as 3D guidance for jobsite machinery. Topcon is present in Africa through a dense network of reseller, ensuring a busy activity for clients, their projects and local jobsites.


Sixense Mapping just broaden its services offers on one hand, its acquisition solutions by drone, LiDAR on board helicopter or even Mobile Scan already carried out in France and Europe, and on the other hand its data management solutions for a better operational performance:

  • Change detection: remotely monitor engineered structures, natural areas (cliffs, vegetation…);
  • Exploitation follow up: surfacing project optimisation, monitoring of earthworks, monitoring of quarries & mines.

Helimap has joined the Sixense Group

Helimap is specialised in precision helicopter-borne LiDAR mapping, with a solid international reputation. The Swiss company, based near Lausanne, established itself on the market thanks to its innovative LiDAR system, adapted to complex terrains and tailor-made applications.  

With the acquisition of Helimap, Sixense Group is strengthening its position in 3D capture and modelling technologies for existing assets, a strategic entry point into the digitisation of construction and infrastructure operations. As a result, Sixense is now a leading global player in 3D digitising technologies.

New CIRIA guidelines on Earth Observation and InSAR technology in civil infrastructure

We are delighted to announce that a consortium led by Sixense and Imperial College London (with support from experts at Royal Holloway, Crossrail and Thames Tideway) has been selected to produce a CIRIA (Construction Industry Research and Information Association) guidance report on the application of ‘Earth Observation and InSAR technology in civil infrastructure’. This report will draw on the extensive experience of the consortium members and will detail current practices, illustrated with case study examples, and outline respective advantages and limitations of the various techniques to assist all users and, in particular, those involved in asset management and construction. A separate online database of case studies will also be developed in parallel by CIRIA to support the guidance document. We understand that this document will form an important review, of current practices and ongoing developments, to inform newcomers to Earth Observation as well as those already using such technologies.

Civil engineering and infrastructure (construction, maintenance and monitoring) are activities which demand high spatiotemporal accuracy, precision and detail of observations and measurements. Satellite borne remote sensing techniques are now able to produce data and information of a quality which satisfies such requirements. Yet there are few standards and regulations for best practice in the production and use of Earth Observation products. CIRIA has therefore recognised a need to inform stakeholders, to realise the full potential of Earth Observation techniques in both research and commercial operations; hence this guidance report will form a much needed and important step towards establishing the employment of Earth Observation techniques as a matter of ongoing best practice for asset management in all infrastructure projects.


The guidance document will be published in 2021. For more information, please contact
