 Summary:
 By intensive stratification of our society, designers and contractors are faced with a variety of requirements and problems which they havenever had encountered in their practice before. The complexity of the problem, but primarily inexperience, results with omissions and errors in designing and construction works. When those errors occur in residential buildings, not only that they reduce building's service life, but also, to a considerable extent, reduce living comfort and quality of life of its residents. This paper presents a solution to the problem, due to failure during installation of mechanical equipment in residential-office building, in Sremska Street in Novi Sad. The failure occured on the pool water pump located on the top of the building. The pool is an integral part of an appartment. The omission is reflected in rigid connection between the pump and the reinforced-concrete slab of the floor structure, but also in rigid pipes passage through reinforced-concrete elements, which led to the noise level that was significantly above the allowed values at a given building. The problem was repaired by implementing appropriate elastic connection between the water pump and the concrete bedding, which is achieved by using shims, that are a mixture of neoprene rubber and cork. The mechanical room is sound insulated by mounting panels of expanded cork and profiled sponge on the walls and doors of the room. Implementing these procedures reduced noise caused by the work of water pump and related equipment to the acceptable level.
