The construction sector is the oldest and the most important branch of technology and it deals with the construction of all types of roads, railways, architectural buildings and other. Construction is generally divided into building and civil engineering. Building construction includes residential (family houses, residential buildings), public (trade, catering) and commercial (industrial, agricultural) facilities. On the other hand civil engineering includes traffic direction (road design), structural direction (bridges, dams, tunnels), hydro-technical direction (maintenance of sewage and water management facilities), geotechnical direction (design and execution of various interventions on the ground). The Croatian construction sector is a significant economic activity that holds an important place in the Croatian economy and it is based on free competition and free enterprise. The construction sector raises the level of assets through its activities, which leads to opening opportunities for longterm growth.
