What is new on the Porte de Thiais Station ? / Prolongement de la ligne 14 au Sud du Grand Paris Express
The main civil works are close to completion and the overground station buildings show their shapes: the northern building for the Marché de Rungis, the T7 tram and the TVM (Trans-Val-Marne) bus line; the southern building also with a connexion with the T7 tram and the Belle Epine Shopping Center.
Inside the station, the mezzanine level on a suspended slab is finalised over the track, the steel truss and their cladding is in progress and the different service utilities are already in place.
Motorway extension – Greece
Motorway extension – Greece
In March 2022, setec tpi – Salfo JV signed a new independent engineer Contract in Greece. This contract covers the 75 km motorway extension between Patras and Pyrgos integrated with the existing Olympia Odos concession (Elefsina – Korinthos – Patras – Pyrgos – Tsakona) and which will serve the site of Olympia and boost the western part of the Peloponnese.
This renewal of confidence in setec by the Greek authorities and the concessionaire is a strong testimony to the quality and satisfaction of the services provided.
Indeed, the Olympia Odos motorway, which we accompanied to its commissioning five years ago, has effectively supported the economic development of the country and improved road safety.
Today, we are proud to renew our partnership with the Greek State and the concessionaire to make this project a new success.
31 may 2022
One year ago, we integrated the existing structures for the Porte de la Chapelle crossing of the future CDG Express line. Now, the new infrastructure advances as a black axis across the night. The launching operations will be undertaken every night of this week.
Kremlin-Bicêtre Station / Grand Paris Express metro line 14 south extension
The ceiling of this station is composed by a glass-timber structure with a shed shape. This is executed by Mathis entreprise, subcontracted by the main works contractor Razel-Bec.
This truss structure has a maximum span of 17m and they are pre-assembled before lifting on site.
setec tpi has undertaken the structural design and construction Project Management of this timber truss, as part of their main Design & Construction Project Management services for the entire metro line 14 south extension within the DJV Elios.
Peace&Log – Rehabilitation of an old gas station in the Porte de Champetret (Paris XVIIth)
The monumental staircase becomes the architectural signature of the Peace & Log project. In a cantilever at the exit of the old gas station, it allows the users to access the market space from the street above.
It is made from a double steel structure: both the structural traditional steel as well as the Corten steel cover. This required a conception that allowed for a transmission of both horizontal efforts towards the existing concret infrastructure and vertical efforts towards the Champerret parking.
The installation of the staircase required a demolition works phase, that included a punctual interruption of the traffic of the bypass.

08/09/2020 – setec tpi takes action by training students on current and future climate challenges
The Ecole des Ponts ParisTech held the second edition of the « Rentrée du Climat » (Climate Back to School) on the 8th of September
Organised all around France, this event aims to massively teach university students about climate challenges by participating in a Climate Collage type of workshop. This workshop lasts 3 hours and is based on the conclusions of the last report from the Intergovernmental Panel on Climate Change (IPCC). With a playful and collaborative approach, it intends to raise awareness of the causes and the impacts of the current climate imbalance. Created 2 years ago, the Climate Collage has already arrived at 75 institutions and to more than 30,000 students.
Proposed by a group of alumni, the second edition of the “Climate Back to School” was organised in the Ecole des Ponts ParisTech on the 8th of September. 194 freshmen(women)-year students took part in it and Alice Blouët (Structures Engineer from setec tpi and Ponts alumni) was one of the hosts of the Collage.
A very good opportunity to make the setec group known to the Ponts students and to share our “Ingénieurs et Citoyens” (Engineers and Citizens) campaign. We will come back next year with more volunteers!
Alice’s testimony: “The Climate Collage workshop has been a success between the students, who have appreciated its playful and collaborative approach. I was impressed by their maturity and knowledge on climate and environment subjects. Several confessed to me that they want to dedicate their careers and lives to fight climate change, it is very encouraging.
The event ended with a presentation held by the “Pour un réveil écologique” association (“For an ecological awakening”). Launched by a group of students, this movement aims to make the universities a foundation of the ecological transition and for big companies to prioritise climate challenges in their business decisions. The message of this movement is as easy as: a company that doesn’t commit to ecological transition today is a company that will struggle to recruit tomorrow.
Thank you to the Ecole des Ponts ParisTech for their warm welcome and to Igor Arduin for the organisation of the event.
