Description:

Development of design documentation and reconstruction of high parameters heating network in accordance with the attached PFU - S14, S17, S23, S26, S33 - set 11

5 tasks

I - Preparation of project documentation and reconstruction of the heating network at ul. Milczańska - viaduct, from point A to point B,

II - Development of design documentation and reconstruction of the district heating network from chamber G33-7-4 to chamber G33-7-16 at ul. Cukrowa and Ledóchowski along with the reconstruction of connections,

III - Development of design documentation and reconstruction of the district heating network from chamber B42 to chamber B43 at ul. Dunikowskiego,

IV - Preparation of design documentation and reconstruction of the district heating network from chamber B64 at ul. Budziszyńska and heating connections to the heat distribution centers in buildings at ul. Inowrocławska 9, 11b, 12b and ul. Budziszyńska and heating connections to the heat distribution centers in buildings at ul. Inowrocławska 9, 11b, 12b and ul. Budziszyńska 36 in Szczecin,

V - Preparation of project documentation and reconstruction of the district heating network at ul. Cukrowa - from chamber G33-3-9 to chamber G33-3-11 and reconstruction of the connection to the building at ul. Sugar 49.

The subject of Task I is the execution of the detailed construction design and reconstruction of the Dn400 high performance overhead heating network from the support at point A to the channel network at point B, consisting in its replacement with a new heat pipe with a diameter of Dn 400, made in pre-insulated technology in a casing made of a rolled pipe spirally made of galvanized steel strip. In addition, teletechnical sewers without fiber optics must be designed and constructed along the entire heat pipeline route. The works should be carried out along with the reconstruction of the area, and then the as-built documentation should be prepared. Note: whenever in the description above the connection to the building is mentioned, it should be understood as introducing pipelines into the building and connecting them with existing pipelines. However, if we are talking about making a connection to a node in a building, it should be understood as connecting the pipeline to the first valves cutting off the node in the node's room. Restoration works in the areas managed by ZDiTM should be carried out in accordance with the conditions described in ordinance No. 40/2014 issued by the Director of ZDiTM in Szczecin of 15.10.2014 (link to ordinance http://zditm.szczecin.pl/uchwaly/zarzadzenie_40_2014. pdf).
