Civil engineering is despite the current crisis in Slovenia an important industry that is constantly evolving and growing. Information about civil engineering services are disordered and scattered across the web. Several companies offer their specific services in different ways, so users are often confused and its difficult for them to obtain all needed informations. It also takes a lot of time to find proper informations. Our main goal is to find out about the options of making a semantic catalog of civil engineering services. Semantic catalog is a web site where they collect all the information about existing services that are clearly and systematically arranged. Long- term use of this application will be achieved with the option to spread the range of existing services and an easy integration of data. The aim or the result of the thesis is also Semantic Web application catalog of civil engineering service itself. It allows the interactive display of all services from a particular provider, thereby setting up a database or integration between users and service providers on a single site. Companies can add service itself to the database where the data is held. Before that all the informations have to be checked and approved by an administrator or the third person. Only then they are available to all internet users. These services can be compared according to different criteria: location companies as service providers, assess them by prepaid users, price range, etc. If the application showes up to be successful, it will be a very large gain, because in the age of computers and sedentary lifestyles are of paramount importance to the user as soon as possible to find quality information . This would not only facilitate access to information, but also to improve their quality. Finally it brings also benefits to the providers, as they can get in this way more costumers. Our application semantic catalog of civil engineering services will establish the recognizable "Fair Home on the Web", which would run 24 hours per day.
