Technical requirements: This notice is for depositing and possible temporary storage/long term storage of TBM masses (TBM, tunnel boring machine) from the New Water Supply Oslo
The intention of this voluntary ex-ante transparency notice is to examine the possibilities for landfill sites for masses and possibly temporary storage/long term temporary storage of TMB masses in the Oslo region.
The total need for a landfill site(s) for masses is maximum approx. 650,000 tfm3 (theoretical solid cubic).
In any procurement of landfill sites for masses and possible temporary storage/long term temporary storage of TBM masses, minimum capacity requirements will probably be set for the landfill site for practical and financial reasons. VAV encourages however all those with capacity of more than 10,000 tfm3 to contact us. It ought to be possible to keep the masses for 4 years for any temporary storage/long term temporary storage.
Vann- og avløpsetaten (VAV) [the Agency for Water and Sewage] handles the sewage water and supplies Oslo's population with drinking water. This is financed through water and sewage fees. The Agency for Water and Sewage is responsible for the development and operation of the water and sewer systems in Oslo. The Agency for Water and Sewage is responsible for the operation, maintenance and renewal of the city's treatment plants, as well as the pipeline network and pumping stations for both drinking water and sewage water. Other primary assignments are the management of water source areas, monitoring the waterways in the city, guidance and information to customers, subscribers and society in general.
One water source and one water treatment plant currently supply about 90 percent of the population in Oslo with drinking water. This makes the water supply extremely vulnerable.
Therefore, Oslo Municipality is now building a reserve water supply and we are planning new water supply tunnels (trunk network).
The project New Water Supply Oslo (NVO) shall carry water from the new water source, Holsfjorden, to the new water treatment plant at Huseby. From Huseby clean water will be transported by tunnel to Sagene and further to Disen and then to Trosterud, and from the existing water treatment plant at Oset (Kjelsås) to Disen. The tunnels will be drilled both conventionally and through the use of TBM (tunnel boring machine).
This notice is for depositing and possible temporary storage/long term storage of TBM masses from New Water Supply Oslo (NVO). This site has further information on the New Water Supply Oslo project as well as information on the contracts in the project.
landfill sites for masses and possible temporary storage/long term temporary storage for TBM masses. Contracts must therefore be signed with one or more landfill sites that have the required licences for landfill and temporary storage/long term temporary storage of TBM masses. We would like the landfill site(s) to be located within 200 km of driving from the site location at Verkseier Furulunds vei 7 and the site location at Huseby School. This is to minimise the environmental impacts from transporting the masses.
There are currently some minor uncertain factors concerning the masses, e.g. in relation to the scope, dates of availability, and condition.
The intention of this voluntary ex-ante transparency notice is to examine the possibilities for landfill sites for masses and possibly temporary storage/long term temporary storage of TMB masses in the Oslo region.
The total need for a landfill site(s) for masses is maximum approx. 650,000 tfm3 (theoretical solid cubic).
In any procurement of landfill sites for masses and possible temporary storage/long term temporary storage of TBM masses, minimum capacity requirements will probably be set for the landfill site for practical and financial reasons. VAV encourages however all those with capacity of more than 10,000 tfm3 to contact us. It ought to be possible to keep the masses for 4 years for any temporary storage/long term temporary storage.
- - annex 2 'Rapport fra Follobanen som inneholder vurderinger knyttet til kvaliteten av TBM-utfyllingen på Åsland, inkl. kornfordelingskurver'. Note: The report only gives information such as corn distribution curves, water sensitiveness, permeability, and frost susceptibility, the TBM masses conditions, general information about the settling potential and assessment of the landfill's quality. It is also worth noting that we expect less hard rock types and less fine masses in the TBM masses at NVO when compared to the Follo Railway.
