The earthworks begun in January 2005 have now been completed: tracks have been laid out, forests cleared and land drained and prepared, which meant bringing 500,000 m3 of sand and laterite to the 120 hectares of the site.

The quarries of sand and laterite which had been opened to supply the Soyuz site, have now been closed. The report by the regional directorate for cultural affairs (DRAC – Direction Régionale des Affaires Culturelles) concerning the archaeological research carried out on the EVA quarry, mentions the discovery of Amerindian remains, several thousand years old.

The infrastructure works have begun.

The flame trench, which deflects the launcher's exhaust gases, has been dug. Excavating required the removal of 200,000 m3 of material, half of which was granite. This is subsequently crushed for reuse at the appropriate calibre in civil engineering projects, roads and other services.

The foundations of the principal buildings have been laid or are being completed, as have the initial layers of the front zone (launch zone) and the Launch Control Centre (CDL –Centre de Lancement).

The roads and services, power networks and air-conditioning systems are being installed according to the provisional schedule.

At the same time, calls for tender for production of the 'Fluids and Low Voltage' systems, and 'Protective Security Facilities' have been issued.

Vitrociset (Italy) was awarded the first contract and Clemessy the second. The contracts were signed for a total of 17 million Euros, out of a total investment in infrastructures of 135 million Euros before tax.
