supplied by measurement instruments on information about jack's stroke and jack pressure which were fed to a specially designed computer to control the automatic lifting operation. A fully independent outside electronic leveling system was attached to the computer control, which secured the exact levelling information, and could stop the lifting operation in case of mislevelling greater than 5 mm. One of two working Pc-At clones was collecting and monitoring of over 24 essential data during the performance operation which was finished without mistakes. The last lifting operations were performed at level +39,69 m, while the top of the dome had reach approximately 80 m in elevation. With the lifting method no risky and complicated assemblies were necessary at this height. All the covering works of the copper sheet on wooden basis and the cross had been performed in March and April, while the dome was still on the ground. After the lifting of the dome, the pendentive was assembled again at ground level underneath the main dome. It represents the transitional tie element through which the rectilinear plan of the church naos changes to the circular plan of the main dome. With the lifting of the pendentive, the central part of the church was rounded off. The structural connection between the pendentive and the main dome supports the dome in four positions. It was done by means of hydraulic jacks capable to produce 3000 kN each (12.000 kN in total). The pendentive will suffice for later additional loads from applied mortar, mosaic cladding and marble cladding on the facade. The pendentive was lifted again by chains. The weight of the pendentive, about 1100 Mp, spanning in perpendicular direction 24*24 m and 14 m height was lifted to 28 m beneath the main dome. This was achieved during two days at the end of January 1990. It was lifted in 36 hours, with speeds at 2,0 m/h. It reached an accuracy within the prescribed technological design with 5 cm tolerance. With this work the structural part of the church was finished. Interruption of works After the NATO bombing of Serbia in 1999, the works were halted again. Patriarch Pavle, known for his asceticism, thought that such an expensive works are inappropriate when people are beaten and impoverished. After becoming a prime minister in 2001, Zoran Đinđić talked with patriarch and convinced him to continue the works. Final works , the exterior
