Install concrete Blisterliden

Scaffolding construction at Blisterliden wind farm

We have been commissioned by Omexom to carry out substation construction within the Blisterliden wind farm, a strategic project that promotes the development of renewable energy in the region.

Our assignment includes the casting of a slab on ground, foundations for apparatus installations and a transformer pit. For the transformer pit, a watertight casting is carried out where both the slab and the walls are cast in a single continuous casting, which guarantees the highest possible safety and durability of the structure.

The project is under construction and is expected to be finalised in 2025, when the substation will play an important role in ensuring stable and efficient power transmission from the wind farm.

Environmentally friendly and flexible cable and pipe laying

In this project, we have used horizontal directional drilling (HDD) as an innovative and sustainable method for cable and pipe laying. This technique has become a first choice in situations where traditional excavation would be both costly and environmentally stressful. Guided drilling offers a solution that minimises the impact on the surrounding environment while providing flexibility in the installation process.

By using horizontal guided drilling, we were able to successfully overcome these challenges. The technology allows for precision-guided drilling that can be adjusted to avoid obstacles, making it ideal for complex installation environments. The installation was carried out without the need for extensive excavation work, which not only reduced costs but also significantly reduced the environmental impact. An additional advantage of this method is its independence from groundwater levels. This allows drilling to be carried out under varying ground conditions without risking impact on water resources or stability.

The project resulted in the successful installation of cables and pipes through the challenging areas, with minimal impact on both terrain and infrastructure. This solution proved to be significantly faster and more cost-effective than traditional methods, and the environmentally friendly aspect contributed to a sustainable end result. By using horizontal directional drilling, we not only achieved the technical and economic objectives, but also ensured that the project was carried out in a way that preserved and protected the natural environment. This reference project emphasises the importance of choosing the right technology to meet modern demands for sustainability and efficiency in cable and pipe laying.


Unnamed design 1

E4 parallel road between Öjebyn and Norrfjärden

This project involves the construction of a new parallel road along the E4 motorway between Öjebyn and Norrfjärden. The aim of this major infrastructure project is to improve traffic flow and safety on one of the busiest roads in the region.

The project is being carried out using a combination of technologies and traditional construction methods to achieve the high standards of quality, sustainability and environmental protection. Work stages and techniques for the construction of the parallel road:

  • Wood piling is carried out to stabilise the ground and ensure the durability of the road.
  • A 2000mm migration barrier is being installed to protect both road users and wildlife.
  • Excavation works and road construction are being carried out to prepare the ground and build the road foundations.
  • Paving work is underway with high-quality asphalt to create a durable and smooth road.
  • Installation of modern road lighting is underway to improve safety along the road.

The project is progressing according to plan and is expected to improve infrastructure and road safety in the area once completed.

Reconstruction of junction at Abisko Östra and Nuolja E10

The reconstruction of the junction at Abisko Östra and Nuolja along the E10 aimed to improve road safety and increase accessibility. The work included the installation of a new 1000 mm culvert under the E10 for better drainage, the extension of bus stops for increased traveller comfort, the upgrading of the water supply system, and the installation of traffic information signs.

The project was successfully implemented and resulted in significantly improved road safety, more efficient water drainage, and a modernised public transport infrastructure. The upgraded infrastructure now contributes to a safer and more efficient traffic environment for both local residents and visitors to the area. The work was carried out and included:

  • Installation of a new 1000 mm culvert under the E10, This measure was central to improving drainage and reducing the risk of flooding during heavy rainfall and spring floods.
  • The bus stops along the intersection were extended and modernised to increase accessibility and comfort for travellers, with particular attention to people with disabilities.
  • The water and sewerage system in the area was improved by installing new pipes and reinforcing existing infrastructure, ensuring long-term functionality.
  • New signs were installed to provide real-time information to road users, helping to improve safety and efficiency in traffic flow.

From demolition to new installation at Råg, Havre and Vetegatan in Piteå

The project involves the rehabilitation and upgrading of existing water and sewerage systems (WSS). The work includes demolition of old water pipes, laying of new water pipes.

The first phase of the project consisted of the demolition and removal of the existing water and sewerage systems. The demolition work requires careful planning to prevent future leaks and system failures. After the demolition, the installation of new water and sewerage pipes will start. These pipes are designed to meet modern standards and requirements for durability and efficiency. Careful positioning and sealing of the pipes to ensure they are properly connected and free from potential leakage points. We use high-quality materials that guarantee long service life and resistance to corrosion and other types of damage.

Methods we used in this implementation:

Relining
Relining is a method we use where new pipes are inserted into the old pipes without having to dig up the entire system. This method is both cost-effective and time-saving, and reduces disruption to surrounding infrastructure and communities. The process involves both inspection and insertion of new pipe.

Directional drilling
Directional drilling is a technique we use to install new pipelines underground without having to open up large shafts. It is particularly useful in densely populated areas or where traditional digging would cause significant disruption.

Three-wire shaft in Street
Finally, the project involved three-pipe shafts, which meant that three separate pipes (for water, sewerage and possibly stormwater) are installed in parallel in the same shaft.


Reference project Infra Terass Lulea from V 3

Terrace to the property Lejonet Luleå

The terrace project in Luleå is a shining example of landscaping that transformed the outdoor environment into an inviting place for visitors. Combining skilful terrace construction with careful ground planning, a functional and aesthetically pleasing space was created for visitors to enjoy.

The first stage of the project involved careful soil investigation and analysis to ensure that the terrace would be built on a stable foundation while preserving the natural beauty of the surroundings. Taking into account the geographical location of Lejonet and the climate of Luleå, sustainable material choices and drainage systems were also taken into account to ensure long-term sustainability.

Through a careful combination of technical expertise and creative design, the project team succeeded in creating a terrace at Lejonet that not only fits perfectly into its surroundings, but also offers a comfortable and beautiful place to relax and socialise. This project clearly demonstrates how carefully planned landscaping can transform a property into an oasis of beauty and functionality.
