This paper demonstrates one more example for the buildings to be constructed in Yerevan. Armenia is well known to the international professional community as a country where seismic isolation technologies are well developed and widely implemented due to research and design works of the author of this paper. Structural advantages of seismic (base or roof) isolation systems are obvious; however, clients are always interested to know also about the cost-effectiveness of these systems. Therefore, the relevant comparative analyses for the fixed base and base isolated buildings were carried out by the author in the past. In the given case, the client ("ASEDL" LLC), which is going to start a project on construction of a residential buildings, has requested to demonstrate the cost-effectiveness of base isolation strategy in case of its application in this project. With this purpose a comparative analysis of the construction cost of the bearing structures of Reinforced Concrete (R/C) buildings with application of innovative base isolation technology vs. the construction cost of the same buildings with conventional design (fixed base) was carried out and presented. They were designed by “ARCHANGEL architects” company and the sketches of this conventional design were kindly provided by the "ASEDL" LLC to the author. Paper briefly describes the structural concepts of both buildings, namely, fixed base and base isolated. Obtained results have shown that due to application of base isolation the construction cost of the bearing structures of base isolated buildings could be reduced by about 1,200,000 USD.
