The project provides for the reconstruction of the internal engineering systems of the medical building of the KNP "City Hospital of Emergency and Rapid Medical Care" ZMR in the city of Zaporizhzhia, in particular, the systems of centralized provision of gaseous medical oxygen, medical air with a pressure of 4.0 bar, carbon dioxide, nitrogen, medical vacuum, as well as the anesthetic gas removal system (AGSS), the personnel call system and the ventilation and air conditioning dispatching system. The project provides for the installation of two oxygen gasifiers on the territory of the hospital, which provide the main and backup sources of oxygen supply, with additional backup at the expense of existing oxygen concentrators. The supply of gaseous oxygen to the medical building is carried out by stainless steel pipelines laid by an overpass, with further distribution across the floors by copper pipelines to the points of connection of medical equipment. The operation of the oxygen equipment is provided for around the clock. The design solutions provide for the installation of systems for compressed medical air, vacuum, carbon dioxide and nitrogen supply, as well as equipment for end points of medical gas consumption, pressure control and signaling systems. The design was carried out taking into account the principle of duplication of sources of vital gases, safety requirements, and current state building codes and regulations. The class of consequences (liability) of the construction object is CC2.
