The subject of the contract includes the execution of construction works on three sites, namely: Lot 1: SUBJECT: Rehabilitation of Ivan Vazov Street from Lozenets Blvd to Republika Blvd. Ivan Vazov Street is part of the secondary street network, which starts at Lozonets Street and ends at Republika Blvd. (Republican Road III -5031 Opan-Galabovo), without prejudice to it. The street is 301.62 m long, class IV, with a design speed of Vpr=50 km/h. The design solution is tailored to the existing situation, with 5 horizontal curves. Design gauges are consistent with the existing street gauge and are as follows:0+000,00 ÷0+019,97m – 6m; 0+019,97m ÷0+089,96m – 5,8m; 0+089,96 ÷0+139,95m – 6m; 0+139.95m ÷0+229.95m – 5.8m; 0+229.95m ÷0+280.07m – 6m; 0+280.07m ÷0+301.42m – 5.8m. Drainage will be carried out through the longitudinal and transverse nalkonas of the street lane. It is planned to build two new rain-reception shafts at the intersections with Pirin Street and Penyo Penev Street, which will be discharged into the existing sewerage system. It is envisaged to replace all curbs in the range of the street, with the new curbs being 15/25/50 cm. In the entire section of the existing street lane, the existing asphalt pavement is removed and the following construction is laid: Dense asphalt concrete E=1200Mpa with a thickness of 4cm; Non-dense asphalt concrete E=800Mpa with a thickness of 6 cm; Unsorted crushed stone with fr.0-63mm thickness 30cm. for local repairs. The pavements are planned to be paved with concrete slabs 40/40/5, on cement-sand mortar 1:3-5cm and NTC 20cm. The transverse slope is 2.0% towards the curbs. Lot 2: SUBJECT: Rehabilitation of Strandja Street. Strandja Street is part of the secondary street network, which in this project starts from Chaika Street and has a length of 370.00 m, class V, with a design speed of Vpr=40 km/h. The design solution is consistent with the existing situation, with 4 horizontal curves. The design dimensions are consistent with the existing street gauge and are as follows: -0+000,00 ÷0+110,00m – 6m; -0+110,00m ÷0+150,00m – 6,8m; -0+150,00 ÷0+220,18m – 6m; -0+220.18m ÷0+370.00m – 5.5m. Drainage will be carried out through the longitudinal and transverse nalkonas of the street lane. It is planned to build two new rain shafts at the junction with Kaliakra Street and to clean and raise the existing ones to the level of the new level. It is envisaged to replace all curbs in the range of the street, with the new curbs being 15/25/50 cm. In the entire section of the existing street lane, the existing asphalt pavement is removed and the following construction is laid: Dense asphalt concrete E=1200Mpa with a thickness of 4cm; Non-dense asphalt concrete E=800Mpa with a thickness of 6 cm; Unsorted crushed stone with fr. 0-63mm thickness 30cm. for local repairs. The pavements are planned to be paved with concrete slabs 40/40/5, on cement-sand mortar 1:3-5cm and NTC 20cm. The transverse slope is 2.0% towards the curbs. Lot 3: SUBJECT: Reconstruction of Plamak Street. Plamak Street is part of the secondary street network, which in this project starts at N. Y. Vaptsarov Street and ends at Rose Valley Street. Flame Street has a length of 597.82 m, class V, with a design speed of Vpr=40 km/h. The design solution is adapted to the existing situation, with 5 horizontal curves. The design gauge is consistent with the existing street gauge and is 5.9 m along the entire length of the street. Drainage will be carried out through the longitudinal and transverse nalkonas of the street lane. It is envisaged that the existing GCs will be cleaned and raised to the level of the new level. All curbs in the range of the street are replaced, with the new curbs being 15/25/50 cm. In the entire section of the existing street lane, the existing pavement is removed, and after compaction of the foundation, the following construction is laid: Dense asphalt concrete E=1200Mpa with a thickness of 4cm; Non-dense asphalt concrete E=800Mpa with a thickness of 6 cm; Unsorted crushed kavka with fr.0-63mm thickness 35cm. The pavements are intended to be paved with concrete slabs 40/40/5, on cement-sand mortar 1:3-5cm and NTC 20cm. The transverse slope is 2.0% towards the curbs. Full information on the scope, volume and technical requirements for the performance of the contract is described and regulated in the ‘Technical Specifications’, an integral part of the procurement documents.
