An overview of methods for evaluating comfort on tram tracks is given in this paper. Tramway systems differ in many aspects from standard railway tracks and, therefore, standards developed for standard rail lines have to be analysed and evaluated. Equivalent level of vibrations, Sperling ride index, and several methods proposed in EN 12299 are described, and these methods are compared on two trial tram sections 21 km in total length. Conclusions and recommendations for measuring ride comfort on tram tracks are presented.

Some usual hydrological methods and the hydrological model EBA4SUB are used in the paper to determine the design peak discharge for various return periods for catchments in Bosnia and Herzegovina. The aim of the paper is to test for the first time the EBA4SUB model in the selected catchments. The results obtained by the EBA4SUB model compare well with other related methods. The advantages of the model lie in the fact that it takes into account physical processes taking place in the catchment, influencing formation of surface runoff.

The Geographic Information System (GIS) is a useful technology for managing spatial databases, which are the basis of the Pavement Management System. When creating a pavement management system in GIS, the needs and available resources of individual road authorities should be considered. This paper describes establishment of a simple database management system for small city administrations. The database was created by manual collection of pavement condition data at several unclassified roads in the city of Osijek. Based on collected data, the system calculates the PSI index and compares pavement condition.

The comparison of the traditional (budget-funded) public building procurement model with the public private partnership (non-budget funded) model is presented in the paper. Public service buildings procured based on the traditional model and those procured according to the PPP model are compared in the scope of research involving nine buildings realized in the Republic of Croatia. The results point to greater efficiency of the PPP model in the construction of public service buildings, with regard to both cost and time of construction work.

Recommendations for enhancement of performance of RC beam-column joints under seismic effects are presented in this study. The aim is to evaluate the use of lowstrength concrete with plain bars without stirrups in the joints. An additional aim is to study behaviour of joints in the aforementioned conditions under cyclic loading. Five specimens with various reinforcement configurations were produced and tested in the experimental process. Based on results obtained in the study, it is concluded that the stirrup arrangement in the joints, and the use of at least 90-degree hooks in longitudinal reinforcement of beams, are critical parameters for the performance of existing structures.
