SENSITIVITY ANALYSIS OF FACILITIES LIFE CYCLE COSTS

Life cycle cost analysis of the constructed facilities provides insight into the planning, design, construction, operation, maintenance and disposal costs of the facilities. By applying this method during the early design phase it is possible to reduce maintenance and operating costs, plan future costs of ownership and prevent or reduce the impact of business interruption due to the maintenance and functional usability. The results of the life cycle cost analysis of facilities depend considerably on the period of life cycle cost analysis and the applied discount rate once net present values are populated. This paper presents life cycle costs case study analysis of the public facility for two different analysis periods, one of 30 and another of 50 years. Facility life cycle costs for both analyzed periods have been discounted to net present value using five different discount rate factors. Predicted construction costs are calculated based on Croatian construction standards, and operation and maintenance costs are based on analysis of historical data of similar constructed facilities in Croatia.
