towers of contact network around fountain on the central part of the Square and twenty-eight towers of contact network, as well as numerous contractors on a small space, short deadline for works performance and constant traffic corridors, which had been formed during entire works performance, then it becomes clear why reconstruction of the Slavija Square was the most complicated”, concludes Savić. Additional 'burden' for our teams was that reconstruction of the right side of Boulevard Oslobođenja and two sections in Ruzveltova street were performed simultaneously with reconstruction of Slavija Square. Again, this was not the end of our challenges. Savić adds that it was most difficult when they had been engaged in three phases of this project at the same time, and works had also been aggravated by constant traffic going on at the Slavija Square and Boulevard Oslobođenja. “In urban areas, for this type of reconstruction, construction works for constructing new foundations are extremely demanding due to numerous infrastructures. We faced the following on the field: concrete pipes for laying cables, electrical conductors, optical ducts, water sewerage, household connections etc.”, concludes Savić.
WORKING AT DAY AND NIGHT
We had a very complex project with demanding deadline before us. One thing we are proud of is good organization of the project and rational usage of human and material resources. Most of the project was performed in two shifts in day regime. The biggest recorded number of workers in one shift with subcontractors was 20. “Considering the fact those were works on conRekonstrukcija trga - najzahtjevnija faza poduhvata Square reconstruction - most demanding project phase
tact networks, which fall in highly risky group, special attention was paid to safety measures at works performance. Here, situation was difficult, since we worked under charge, with traffic going on”, said Savić. Slavija Square is very important for everyday life of Belgrade inhabitants. Capital reconstructions of this Square, at this location are performed once in 50 years. Due to this fact, equipment we installed represents state of the art in technical sense. Solutions used in other big cities were applied in Serbia for the first time. For example, intersections tram-trolleybus were installed and these do not have interruptions in continuous power supply, i.e. vehicles are always under electrical power charge. Goran Vesić, the City Manager, estimated that works were performed well and in highest standards. “We tried to perform this project in as short deadline as possible. Reconstruction was through and serious, all installations were replaced, new lanes added. Apart from this, bicycle lanes were constructed in Ruzveltovoj street and Boulevard Oslobođenja. Slavija was constructed in the way it is more passable for traffic and pedestrian crossings are no longer in Slavija itself, and bus stops were moved as well“, said Vesić. We are pleased to say that we significantly contributed to accomplishment of this project goal. We made it, even five days before deadline expiration. Belgrade got a better tram flow, organized traffic lanes and canalized throughput, with stress of highest level of safety and better coordination in traffic for entire route. New traffic infrastructure provides us with possibility to have 140,000 pedestrians and twice as more vehichles on this square on daily basis.
SLAVIJA Slavija Square is one of the busiest Belgrade locations, where, along with vehicles, there are three other transport means: trams, trolleybuses and buses. It is situated 1.5 kilometer south from Terazije. This place used to be known as Belgrade hunting ground up until 20th century. It stayed this way up until the moment when Scottish businessman Francis Mackenzie decides to build a house at this location. Afterwards, new age history of this location started.
MODERNIZATION OF RAILWAYS RS INFRASTRUCTURE IN MAY 2017, ELNOS GROUP COMPLETED ITS PART OF WORKS IN BIG PROJECT OF RECONSTRUCTING AND MODERNIZATION OF SYSTEM FOR SIGNALIZATION AND TELECOMMUNICATION OF THE RAILWAYS OF THE REPUBLIC OF SRPSKA. THESE ARE FOUR PROJECT PHASES: POWER SUPPLY FOR SS AND TC SYSTEM FROM DISTRIBUTIVE NETWORK, POWER SUPPLY OF SS AND SUBSTATION SYSTEM FORM CONTACT NETWORK, HEATING OF SWITCHERS AND LV DISTRIBUTION. WITHIN THIS PROJECT, WE RECONSTRUCTED AND MODERNIZED SIX RAILWAY STATIONS: OSTRUŽNJA, ŠNJEGOTINA, JOŠAVKA, ČELINAC, VRBANJA AND BANJA LUKA.
