Czechia – Construction work – Brno, Pekařská - rekonstrukce kanalizace a vodovodu

The subject of the public contract is the reconstruction of the sewerage and water supply, including sewerage and water supply connections, further the entire public space will be adapted including the modernisation of the tram line, complete renewal of communications, parking and stopping areas, pavements, including the reconstruction of public lighting and trolley wiring. Sewerage and sewerage connections: The sewerage in Pekařská street dates from 1898 to 1901 and will be reconstructed over a total length of 680 m, of which by trenchless method (in a trench) over a length of 146 m (in profile DN 1000/1500 over a length of 131 m and 500/750 over a length of 15 m) and in open excavation over a length of 535 m (in profile DN 1000/1500 length 27 m, DN 800/1200 length 430 m, DN 500/750 length 61 m and DN 300 length 16 m). The existing sewerage, which will not be excavated during the construction work, will be sealed with a cement-ash suspension. All sewerage connections in the public area with a profile of DN 150 to DN 400 and a total length of 587.1 m and connections to rainwater drains in profiles KT DN 125 – DN 150 with a total length of 279.5 m will also be reconstructed. Water supply and water supply connections: The reconstruction of the water supply from shaped cast iron with heavy corrosion protection will be carried out over a total length of 881.7 m (in profile DN 300 over a length of 442 m, in profile DN 250 over a length of 269 m, in profile DN 150 over a length of 170 m). During the construction of the water supply, temporary water supply will be ensured by means of a temporary water supply from steel pipes Ø 273x6.3 mm and a length of 442 m and from steel pipes Ø 219x8.0 mm and a length of 269 m. As part of the construction, water supply connections DN50, DN80 and DN100 with a total length of 304.7 m will be reconstructed. Hydrovorts: As part of the construction, the reconstructed sewerage in the section Š953304 – Š7 and Š994565 – Š4 will be realised with permanent deep drainage, namely a system of hydrovorts with a depth of 10 m and a quantity of 29. Reconstruction of VO, network relocations: As part of the reconstruction of Pekařská street, the relocation of the existing public lighting and network relocations (CETIN, MU, Vodafone, T-mobile, FASTER, DPMB communication cables) will also be carried out. Tram line: As part of the construction, the double-track tram line will be relocated on large-area reinforced concrete panels with the installation of a groove track NT1 and NT3, in the section from the intersection with Úvoz street to the stop Šilingrovo náměstí. As part of the relocation of the tram line, 2 stops, 22 traction masts, the relocation of the trolley wiring, cable networks, ELP supply cables and NN connections for ELP will be realised. The tram line will be realised over a total length of approximately 653.50 m. The parameters for the renewal of the track must fully respect the internal guidelines of Dopravního podniku města Brna, a.s. (hereinafter "DPMB"): • guideline T07 "TECHNICAL CONDITIONS FOR THE CONSTRUCTION, RECONSTRUCTION AND MAINTENANCE OF TRACKS DPMB" in the valid version. • guideline T08 "TECHNICAL CONDITIONS FOR OPERATION AND MAINTENANCE OF TRAM LINES DPMB" in the valid version. • guideline T09 "TECHNICAL CONDITIONS FOR THE CONSTRUCTION AND RECONSTRUCTION OF TRAM LINES DPMB" in the valid version. This guideline sets the technical conditions for all reconstructions and the construction of new tram lines, resp. track constructions and intersections, which are owned by DPMB, or are being prepared and designed for future ownership by DPMB. Communications: It also includes extensive full-area renewal of communication surfaces and pavements with an area of 16,420 m2. The construction will be carried out in coherent parts. The detailed scope of the works on the communication surfaces is described in the documentation part. Furthermore, the reconstruction of the existing traffic light signalling system (SSZ) at the intersection of Úvoz – Pekařská will be carried out. As part of the reconstruction, furniture (benches, grilles for trees, waste bins, waste screens, barrier posts, bicycle stands, MHD shelters, drinking fountains) will also be realised. The construction must be coordinated with the following actions: • Residence Anenská brána (investor RUBELA, a.s.) • Reko MS Brno – Pekařská (investor GasNet, s.r.o.) • D1 - New laboratory building (investor FNUSA) The contractor is obliged to ensure: • uninterrupted access and entry of IZS vehicles to the Faculty Hospital u sv. Anny, • passability of the intersection Úvoz x Pekařská for public transport vis POV, • uninterrupted entry and exit to the land parcel no. 1728, k.ú. Staré Brno, • at the construction facilities SO 452 Communication cables MU, SO 453 Communication cables VODAFONE, SO 454 Communication cables T-MOBILE, SO 455 Communication cables FASTER and SO 456 Communication cables DPMB, the customer draws attention to the strict conditions of the individual owners of electronic communication networks. The contractor is obliged to ensure the relocations and securing of underground lines of electronic communication networks so that during the entire period of the relocation implementation, there is no interruption of the operation of the infrastructure, with the proviso that the interruption of the operation of the infrastructure at each individual cable connection of the infrastructure may not exceed 8 hours. A detailed description of the scope of the required works is given in the project documentation "Brno, Pekařská – reconstruction of sewerage and water supply", prepared by the company PK OSSENDORF s.r.o.
