Egnatia Odos Motorway
Structural Design of Tunnels & Bridges, Northern Greece
The Firms involvement in this Motorway comprises mainly structural design of tunnels and bridges. Although more than 4 major double tunnels have been designed (Dodoni, Anilio, S1 and S2 of section 5.2.3), bridge design is the Firm's most important contribution. From 1996 to date the firm's involvement in bridge design covered three different types of services, namely: Complete design of bridges for Egnatia Odos S.A. or other Contractors, checking of designs produced by other firms, and general review of designs produced by others.
- Design of the Arda River Bridge, a 667m long bridge with 18 spans of 37m each deck with precast beams.
- Design of Bridge G1, on the Lefkopetra-Kouloura section with four spans totaling 150m and a single shell box girder deck.
- Design of Bridge G1, on the Polymilos-Veria section box girder build in cantilever with three spans, totaling 236m.
- Design of Christalopigi Bridge with a total length of 848m in 16 spans and a curved box girder deck with build in special launched shoring.
- Design of several box girder bridges build in cantilever, including the Mesovouni Bridge, totaling 257m, the G3 Bridge on the Panagia-Grevena section totaling 326m with 3 spans, and G11 Bridge on the Polymilos-Veria section with three main spans totaling 247m.
- Design check of the Venetikos Bridge, with a total length of 636m in six spans.
- Design review of the Arachthos Bridge with a total length of 1036m in 8 spans.
2.2km Vehicular Bridge, Peloponnese, Greece
This was a BOT project awarded by the Greek State to a consortium with Vinci of France as a leader. It provides a link between the Peloponnese, the southern part of Greece, and the main continent along the Western shores of the country between the coastal towns of Rio and Andirio. The link consists of a 2,252 meter long 4 pylon cable-stayed bridge with two spans of 286 meters and three spans of 560 meters, two approach viaducts, with 392 meters on the Rio side and 239 meters on the Andirio side, and a total length of about 2,900 meters. Design and construction of the bridge started in 1996 and the bridge was inaugurated in 2004. In the concession agreement the Firm was a nominated partner of Buckland and Taylor of Canada for the design checking of all elements of the project as well as participating actively in the seismic design concepts. Furthermore, the Firm was a nominated partner of Faber-Maunsell (U.K.) for the supervision and control of all elements of the project. In 2006, the Firm and B. Kolias, it's partner in charge of Structural Design, received two International awards for their contribution to the project: The IABSE (International Association of Bridge and Structural Engineering) award for outstanding structure and the FIB (Federation Internationale du Beton) award for outstanding concrete structure.
Athens International Airport
Master Plan and Structural Design, Joint Venture, Greece
Structural Design & Infrastructure
The Firm was involved in this project during two separate stages. First, in 1979 - 1981 as a member of the GREDECO-NACO joint venture when the original Master Plan was prepared and second in 1996-1998 as a structural designer for various building assigned to the firm by HOCHTIEF AG concessionaire and contractor of the new Airport. In 1979 the Greek State awarded a contract to GREDECO, a Joint Venture of 3 Greek design firms and the Dutch firm NACO to review an existing old Master Plan and produce all designs necessary to construct a new International airport at Spata, northeast of Athens.
The new Master Plan was approved, the preliminary design of installations and infrastructure were finalized and a tender for earthworks was awarded to a contractor. Following the completion of most of the earthworks the work was halted for several years. It was resumed in 1996 when HOCHTIEF AG was awarded a concession to build and operate the new International Airport. HOCHTIEF contracted the preparation of structural designs and shop drawings for various buildings, including: The Air Traffic Control Building and Tower and the Buildings and Ground Equipment Maintenance Complex.
Structural Design of Stations & Traffic Diversion Studies
From 1992 to date the Firm was continuously involved in the Athens Metro Project either under assignment by ‘Attiko Metro’ or by the contractors in charge of implementation in two distinct fields: The structural design of stations, shafts, galleries and tunnel and the planning, design and supervision of implementation of all necessary traffic diversions at the numerous construction sites within the Athens urban area as well as the mandatory relocation of all utility lines (water supply, sewage, electricity, natural gas, telephone) in conflict with the works, were rendered.
