Design of several residential buildings -either multi-storey groups of flats or private villas. Civil, architectural and mechanical studies are coordinated so as to achieve the best aesthetical and functional result combined with safety and economy. The company is also highly expertise in earthquake design of buildings in high seismicity regions. •

Technical Repairing Depot of Athens Piraeus Electric Railways S.A., Greece

Structural design of the building installations used for vehicle servicing and repairing. The building complex consists of 4 statically independent concrete buildings, with a plan of about 140x40m in total. Repairing works are taking place on the ground level areas, while the other storeys are used to host offices. Due to weak soil conditions and vicinity of sea level, a mat slab was selected as a foundation for the buildings. •

Visitors Reception and Servicing Buildings at Katakolo Port, Greece

The project deals with the general upgrade of the land zone in a touristic port situated in Southern Greece. The port receives annually thousands of foreign visitors via hundreds of cruise ships. More specifically, the project includes: A Visitors Reception Building: A three-storey concrete building equipped with the necessary infrastructure for the reception, information and servicing of tourists. The building also houses the office facilities of the relevant staff. Passport Control Building: All visitors arriving at the port pass through this two- storey steel building. The building is designed so that visitors disembarking from the cruise-ships enter from one side, undergo passport control and straightly exit to the city from the opposite side. Offices of tourist police are situated here. Cultural and Exhibition center: Reconstruction and extension of existing traditional building, which will be used as a multiple-activity area and will host cultural and archaeological exhibitions. -

Open air Amphitheater: It is constructed of concrete and used for cultural shows and events.

Area Reformation: The whole area is reformed so that parking, transportation and other related needs are fulfilled. The project includes buildings of about 3000 m2 in total for the reception and service of tourists. The area reformation extends up to 26000m2 . •

Tourism Activities Complex at Corfu Island, Greece

The projects take place in Corfu’s touristic area. It includes: Parking Building: In order to service the high number of visitors, a semi-underground garage building is constructed. The building is made of concrete. Moreover, its roof was planted with trees in order to avoid any environmental impact on the area. -

Two major public swimming pools A traditional hotel


Restaurant and cafeteria buildings.

Thermal Buses Company Depot at Attica, Greece

The project deals with the construction of the building installations of a total surface of approximately 7000 m2, the landscaping, the supply of required e/m equipment and the implementation of all necessary infrastructure of the new depot of the BUSES COMPANY S.A. within a company-owned plot of 44 acres at Anthoussa, Attica. Each building is specially designed in order to fulfill its special use technical needs. A concrete building of about 3400 m2 is used as office installations, while the two other steel buildings of about 1800m2 each, are used for the technical check, repairing , painting and servicing of thermal buses. Special servicing pits are constructed at the basements of the repairing buildings. Special support of industrial cranes is designed for both of the steel buildings.

Infrastructures for New Sulfur Recovery Plant of ERG Raffinerie Mediterranee SpA, Italy

Structural design of infrastructure for refinery, which includes: -

Steel pipe-racks


Industrial equipment and machinery supporting steel buildings


Foundation design for storing tanks, pumps and flares


Concrete control and office building

Design takes into account special mechanical and thermal loads applied on supporting structures. Structural and earthquake calculations comply with Eurocodes and Italian National Codes. •

Infrastructures for OL2K Ethylene Project, Kuweit.

This project deals with studies and detailed design of civil works and steel structures for OL2K Ethylene in Shuaiba industrial area of South Kuwait, owned by DOW. Infrastructures include: -

Steel pipe-racks


Industrial equipment and machinery supporting steel buildings


Foundation design for storing tanks, pumps and flares


Concrete control and office building

Design takes into account special mechanical and thermal loads applied on supporting structures. Structural and earthquake calculations comply with Eurocodes as well as American Codes, as requested by the client. •

Bridges and Technical Works of Petra-Kalloni Motorway, Lesvos island, Greece

The project included the structural design of 5 pre-stressed concrete motorway bridges. Each bridge has a 40m span with two lanes in each direction as well as a bicycle-lane. Several concrete retaining walls are also designed in order to support the motorway and ensure stability of slopes. •

Consulting Studies for Retrofing and Seismic Desing of Viaduct at Bolu, Turkey

The study investigates the failure of the 1600 bearings of the Dûzce-Bolu Viaduct arising from the excessive relative displacements between the span and the piers, during the Dûzce-Bolu earthquake with 7,2R magnitude on 12-111999. Alternative models of the typical 50-meters high single column are studied, taking into consideration or ignoring the soil-structure interaction and investigating the possible role of the dissipating devices. By comparing the results of all analyses, the possible contribution of the different factors to the large displacements is emphasized and the parameters of the appropriate seismic isolation system are designed. •

Rehabilitation of the Macdonald street depot in Paris, France

The study includes the capacity control and strengthening of the existing infrastructure (R+1), in order to support the 5 storey superstructure designed by the architects. A global finite elements model was developed in order to study the linear and non-linear effects of the superstructure on the existing building. The rehabilitation design included both global structure remodeling (e.g. addition of steel X-bracing) as well as detailed structural elements strengthening (jet grouting ect).

Rehabilitation of the National Geographical Institut of France (IGN) in Paris, France

The project includes the complete reconstruction of a 5-story building, with partial demolition of the facades and the construction of 2 additional storeys. In order to ensure that the existing infrastructure sustains the additional loads, light construction materials were chosen for the structure of the new floors and facades (steel and composite structures). In addition, a 4-storey extension to the existing building was designed. This light, metal superstructure had to be founded on a micro-pile system and was designed to be supported by a 3,5m height steel truss, with a span of 18m.

Supervision of the Flamoval garbage incinerator construction, in Pas de Calais, France

The supervision and control of the construction process of this industrial building was undertaken. This reinforced concrete building was founded on a poor quality soil; therefore soil improvement techniques such as ballasted columns were applied. Furthermore, the roof of the incinerator was supported by a wooden truss structure with a maximum span of 43m.

Software Development & GIS applications In-house software •

KatsCAD is an GIS software which manages ortho-photos, digitizes vectors on them and creates topologies and classifies polygons. This software:

⇒ works with Arc/Gis, Autocad , SQL Server e.t.c. ,

⇒ manages the work of all users , gathering information from all workstations and creating a single plan,

⇒ Seperates workspaces in order to be distributed autonomously to the users/operators and

⇒ runs management controls and verifications in order to meet the high standards set by the client

Software for the ortho-corellation and correction of scanned maps in order to eliminate scanning errors and distortion of paper over time as well as the scanned document’s definition of georeference. During the correction, the software uses either grid points which are being identified automatically or points with known coordinates in space.

A module for Autocad map which digitizes and manages polygons, manages scanned maps and orthophotos, organizes each users operation and monitors the performance of the project. The software works with Spatial database (SQL Server 2008 Spatial) which stores the unified work of each user, runs the necessary checks according to the dynamic standards and also redirects the users to the correct polygons. Moreover, the user can set dynamic statistical data which will make easier the monitoring of performance and the quality of works.
