Participation in the execution design studies of the deck and its steel supports. Double box girder structure with 3 spans 68m-84m-55m with a total length of 200m for a deck width of 34.90m.  The supports on piles consist of steel braces assembled in the shape of an inverted cone (corolla). The audacious architecture and the installation procedure of the structure imposed a complete finite element simulation, see details in “Campan, V. / Cazenave, M. / Mangin, Y. M. / Saouridis, C. (1996): Finite element calculation of the Charles de Gaulle bridge, Revue Construction Métallique, n. 1 (1996) “.

Building Securities Exchange-ADX (Abu Dhabi, U.A.E.)

Execution design study for the Stock Securities Exchange (ADX) headquarters building at the new Abu Dhabi Financial Centre Complex (4.500 tons of steel).

Sowwah Island is set to be the new financial centre of Abu Dhabi. Already underway is Sowwah Square, which includes four office towers and the headquarters for the Abu Dhabi Securities Exchange (ADX). The new ADX building is a 5 stories structure with a total surface of 18.000m². The structure is composed of composite slabs standing on 8 steel mega-trusses (mid span 48m), which are supported on 8 reinforced concrete piers. The total weight of steelwork is approximately 4.500 tons.

As a subcontractor of Terrell International (France), we delivered the main execution study of the steelwork part of the building (calculation notes and execution drawings), to be designed according to AISC codes and standards.

Viaduc de l’Austreberthe (France)

The bridge crosses the Austreberthe valley (Normandy, Seine Maritime).

The structure is of the double composite girder type with composite transversal and cantilever beams. It consists of 6 spans for a total length of approximately 471m. The deck supports 2×2 traffic lanes plus two emergency lanes for a total width of 21.6m.

We have elaborated the complete execution design study of the steel structure of the deck including the study of the launching as a subcontractor of the steel fabricator Victor Buyck S.C.

Campus ENS – Paris Saclay (Paris, France)

The Ecole Normale Supérieure in Cachan (E.N.S. Cachan), created in 1912, will move to its new location on the plateau of Saclay.

The project is quite emblematic insofar as it is signed by architect Renzo Piano and awarded as a BIM d’Or project in 2015. The works will be carried out by Campenon Bernard Construction (Vinci).

It is with some emotion that we have participated in this project alongside CBC (the Director of our Design office spent 4 years in this scientific institution preparing his PhD).

We are responsible for the execution studies of the steel structures of the buildings 6 (reception), 7 (amphitheater with 500 seats) and 8 (hall with retractable bleachers) as well as the connecting bridges with the other buildings of the new campus.
