An old district heating culvert in the very centre of Norrk\u00f6ping is being replaced by a new pipe. Narrow streets, tramlines, and protected trees on an archaeological site mean strict requirements for coordination and flexibility during installation.<\/strong><\/h5>\n\n\n

The oldest pipes in E.ON\u2019s district heating network date from the early 1950s and many of the old concrete culverts need renovation.\r\n\r\n\u201cThe utility company has had problems with recurring leaks on this district heating pipe,\u201d says E.ON\u2019s Project Manager, Joakim Viitanen.\r\n\r\n\u201cOne of the challenges are the tramlines that we have to cross and build a chamber next to. We will also be connecting the new pipe in an existing concrete culvert to an abutment on a very busy road. And all this is being done in the centre of Norrk\u00f6ping, which has a considerable impact on the public, so replacing the pipe involves plenty of challenges,\u201d he adds.<\/p>\n\r\n\r\nNew pipeline route<\/strong>\r\n\u201cBut the challenge is not only limited space underground, it\u2019s also the traffic, refuse collection, emergency access roads, access to hotels etc., which has to be dealt with,\u201d says David Svenmar at FVB.\r\n\r\nThe solution has been to build a pipeline running about 650 metres in a new section. The choice to not lay the new pipe along the same route as before is due to the lack of space at street level, and that the existing pipe cannot be completely excavated or be decommissioned, as the supply of heat to customers has to be maintained.\r\n\r\nThe new pipe section offers more space underground compared to where the existing concrete culvert lies, despite there being pipes and conduits for water, electricity and fibre in the ground. It was identified early in the feasibility study that this section could accommodate two DN500\/800 pipes.\r\n\r\nSensitive area<\/strong>\r\n\u201cApart from having to lay a pipe in the centre of the city, the area is also classified as being of special historical interest, which means we had archaeologists observing the excavation. There is also a \u2018biotope protection\u2019 avenue of trees right along the line of the excavation, which we had to protect, so this is a very unusual project in many ways,\u201d says Joakim Viitanen.\r\n\r\nTo ensure the work goes as smoothly as possible requires close liaison with everyone involved, according to Viitanen. This particularly applies to Kanonaden Entreprenad, the contractor doing the work, and FVB, who handles all the planning and contact with the third-party inspector for construction and manufacturing control for the entire project. Peter Tyrholm and David Svenmar are the main FVB experts involved.\r\n\r\n\u201cWe\u2019re also going into all the properties affected to see what we need to do to replace service pipes,\u201d explains Tyrholm, whose office is located near to the excavation site.\r\n\r\n\u201cIt\u2019s rare that a project planner is as close as in this case. FVB has given us planners who are engaged and out on the site when we encounter problems that may mean we have to deviate from the original plans,\u201d says Joakim Viitanen.<\/strong>\r\n\r\nExamples include electrical cables lying at a different level compared to the information provided by their owners, or that rainwater drains run at a different angle to what was expected.\r\n\r\n\u201cIn such cases, having a planner located nearby is invaluable. They can come to the site and we can discuss how to best tackle a problem,\u201d explains Viitanen.\r\n\r\nUrgent replanning<\/strong>\r\n\u201cAt one point during this project, we had to hold an emergency replanning session. We sat with FVB at five in the afternoon and discussed how to solve the problem. Peter and David outlined a proposal that they forwarded to us late the same evening. That level of engagement is needed to keep this type of project moving forward,\u201d he says.\r\n\r\nThe project will be completed in the spring of 2026.\r\n\r\nMore information:\r\nPeter Tyrholm, 013-25 09 47\r\nDavid Svenmar, 013-25 09 44","protected":false},"excerpt":{"rendered":"
