Track and platform contract

In Slagelse, we carried out a track and platform contract as the main contractor, with Bravida Danmark as a subcontractor for the overhead power system.

A positive collaboration between multiple departments

For this contract, we engaged our foundation, construction and groundwater lowering departments.

Our foundation department established a 168 m long retaining wall, executed as a “Copenhagen wall”. The work involved drilling 800 mm diameter holes to a depth of 10–­12 m, into which HEB300 beams were embedded. Additionally, 6 m of sheet piling were installed to stabilise the track bed for tracks in operation.

Our construction department cast foundations for noise barriers, reinforced the existing bridge with support foundations and installed track-bearing cable wells. We also reconstructed the old pedestrian tunnel under the tracks at the station to match the new design.

Our groundwater lowering department assisted in lowering the groundwater level using wellpoint dewatering.

Guided directional drilling

We carried out guided directional drilling under the existing tracks 3 and 4. The sections were 30 m and 40 m long respectively.

The drilling was performed from the ground north of the railway tracks to the receiving pit located between tracks 2 and 3. The work began with a pilot drill, after which a 250 mm diameter casing pipe, containing two 110 mm diameter conduit pipes, was pulled back to the start pit.

We established the receiving pits, and the drilling work was carried out by our partner.
