Our company among its economic-related activities organises trainings in terms of Dynamic Cost Comparison Calculation (DCC) and Life-Cycle costing (LCC). These methodologies are easily taught by the economics and engineering professionals as well. Our colleagues, as experienced trainers, are involved in the effective training process in order our future partners will be able to use these costings during their project preparation work.

These events are not only for knowledge transfer but a very effective platform contributing to set up and increase professional networking and water development.
