Henriksdal

There are three enclosed establishment zones at Henriksdal: one on the mountain at Henriksdalsringen 57-59, one at Lugnets trafikplats, and one opposite the churchyard on Kvarnholmsvägen (see map). Site huts, vehicles and materials required for the work are placed in these zones.

Work will take place between the hours of 7am and 10pm on weekdays. The further away from the zone you are, the less disruptive noise you will hear. The progress map shows how far the blasting operations have progressed at present.

After a lot of preparation work inside the Henriksdal treatment plant, work on expanding and upgrading the treatment plant has now embarked upon a new stage where more work has to be done and more noise is generated. There is now more impact on residents and people working at Henriksdalsringen, and this work is estimated to continue for about 2 years.

Ongoing work at the treatment plant

Where: Inside the treatment plant, we have shut down two storage ponds that are currently being refurbished in order to install the new membrane technology.

Our working hours are 7am to 10pm on weekdays.

The technology tunnel

Where: Inside the Henriksdalsberget mountain, above the treatment plant and beneath the properties at Henriksdalsringen. We are building the technology tunnel needed to provide the new membrane ponds with the technology required. People living on the mountain can hear how we are blasting, and the residents have begun to detect drilling work as well. You can find out more about this work here.

Sludge dewatering building

Where: We are also working on the Stockholm Vatten och Avfall site to build a new plant for handling the sludge produced by the treatment plant. This involves us blasting out rock in order to make space for the plant, and a new building will be constructed on the mountain as well. Sludge is currently handled outdoors at the Sickla plant. When the expansion of the Henriksdal plant is complete, all sludge will be handled inside the mountain and thereby eliminate the spread of unwelcome odours in the local area.

We will need to remove rock spoil from the site during the construction period, which means that trucks will be operating on a number of transport routes. At Henriksdal, these transport routes for inbound and outbound traffic will be located along Kvarnholmsvägen, Värmdövägen, Henriksdalsringen, Danvikshemsvägen and Henriksdalsbacken.

Our blasting and drilling operations will be heard and felt in various ways at Henriksdalsringen.

All residents will feel the blasting operations, and almost all will hear structure-borne noise while we are working under the building in which they live.

We will be blasting on a number of different fronts simultaneously, and the loudest noise will be heard above the tunnel fronts. The structure-borne noise will decline gradually as the various tunnel fronts move forward by about 15-20 metres a week.

Our progress map shows how much progress we have made.

First, we will drill long holes over a period of about three hours. This will cause structure-borne noise, similar to when a neighbour drills in one of their walls. The holes will then be charged with explosive, and then we will blast – this will take about 3-5 seconds.

We expect to have time for two to four blasting operations per day. Blasting will cause vibration in the rock that it will be possible to detect in properties on the mountain, primarily on lower floors.

We will measure every blasting operation to make sure it does not damage the properties.

If you feel that the disruption is so problematic that you cannot remain at home, you will be guaranteed alternative accommodation for the period of the excess noise. We have the option of offering accommodation at very short notice.

Alternative accommodation is available outside Henriksdalsringen 49-51. This alternative accommodation is over one floor and comprises fully equipped and furnished one and two-bedroom apartments. We will be building a larger pavilion with three and four bedroom apartments outside Henriksdalsringen 45-49 during the winter.

We also have a contract with aparthotel Biz Apartment in Hammarby Sjöstad, and with a number of serviced offices.

We will invite you to attend an information meeting in plenty of time before your property is disrupted.

Pre-inspection of homes and public spaces took place in spring 2018. Approximately 75 per cent of Henriksdalsringen was inspected at that time. Since then, interim inspections have taken place in certain parts of Henriksdalsringen. SL also inspected some apartments last summer in connection with work on the Saltsjöbanan Line.

New inspections will be carried out regularly on parts of Henriksdalsringen where this is necessary. You can give us a call or send us an email if you have any questions about the inspection of your apartment.

We have set up a telephone notification service where you can register your phone number and receive notifications about blasting operations about 30 minutes in advance. You can decide whether you would like to receive automatic voice calls or text messages.

We will do everything in our power to make sure that people living nearby are subject to as little disruption as possible.
