Abstract
The paper describes an information system for transforming an "old-fashioned" city infrastructure management system into an interactive system for the future. The paper presents first results from ongoing research into cost analyses and other characteristics of comparisons between traditional and trenchless (Cured-In-Place, CIPP [l]) construction methods for the rehabilitation of sewer pipes at 3 locations (projects) in Zagreb, Croatia. The management of city underground pipe infrastructure has in the last decade experienced large changes in construction techniques, authority policies, and public opinion. The consideration of social costs in reconstruction and installation of underground public utilities is becoming commonplace in most cities. There remain, however, some public utility companies in some countries, including in central Europe, where decision makers have not made significant steps away from traditional methods of construction and continue to work according to old maintenance programs and without proper information systems. The results of this are ailing city infrastructure systems and nowhere near the amount of necessary money available in order to reconstruct all that needs to be improved. The authors are proposing an information system that combines modern trenchless construction technologies with a restructured maintenance, construction and repair program as an optimal means for improving underground infrastructure conditions in cities at a minimum cost. The presented research results are strong indicators of the potential gains a city can achieve by implementing such an information system.
