Abstract
In Northern Greece the largest and most challenging Greek project of design, supervision, construction, operation, maintenance and exploitation is currently taking place. This is the Egnatia Motorway project. With the major part of the 680 km long Egnatia Odos Motorway already constructed and set in operation, several hundred bridges are subjected to everyday traffic loading and are expected to be subjected to small or even moderate seismic loadings during their lifetime. Although these newly established bridges have high durability, over their design life of 120 years, their periodical inspection and evaluation is required to ensure appropriate and prompt maintenance and repair of any damage or deterioration EGNATIA ODOS S.A., the company responsible for the design, construction, maintenance and exploitation of Egnatia Motorway, is developing an integrated Bridge Management System for optimizing the maintenance and repair policies for bridges of our highway network. This system consists of the following features: A Computerized Data Base in ORACLE™, for recording and coding the structural and functional characteristics of Egnatia Motorwaqy bridges as well as the results of their periodic inspection. A Manual, Guidelines of Bridge Visual Inspection, as well as of evaluating and rating the condition of bridges and structures. Bridge Capital Maintenance Software, for the optimal programming of the required capital maintenance activities. A Manual, Specifications, Hardware (sensors) and specific user friendly software tools of on line periodical instrumental monitoring of representative motorway's bridges, for identifying their dynamic characteristics (frequencies, mode shapes, damping), updating their dynamic models and detecting the location and significance of damage. This paper presents the progress on the development and operation of the last feature of Egnatia Bridge Management System.
