We’re helping Port of Copenhagen prepare for the future by constructing a new multi-purpose wharf large enough to handle the largest vessels expected to visit Denmark in the next 30 years.
​
It’s a big, bold, exciting collaboration.
​
At 350 metres long and 34 metres wide, Port of Copenhagen new wharf will be able to handle larger ships, and more of them, improving operational performance. We work side by side with our port clients in operational port environments making sure operations continue throughout construction.
​
50% more containers, 94% more cruise ships and 64% more bulk cargo.
​
Our work
Piling – over 400 x 900mm diameter and 200mm diameter bored piles together with an in situ reinforced concrete deck.
​
Dredging – 1.3M cubic metres of dredging for the approach channel and turning basin.
Excavation – of the reclamation edge to form the slope for revetment and using precast concrete revetment blocks designed with innovative technologies.
​
Casting – 4,000 revetment armour concrete, each laid to a precise arrangement. 20,000m2 of ~1m deep pavement.
​​​
Installing – ducting, stormwater and water supply.
​
Our Environment
Community and ecology were a key focus during this project. From an ecological standpoint, Jönsson Entreprise A/S teams supported the successful relocation of over 200 penguins as a part of the build, assisted in burying a grey beaked whale in collaboration with local iwi, and set up new community gardens on-site. We also worked closely with a local school to provide fun and interactive ways to learn about bridge construction, which resulted in Jönsson Entreprise A/S and the children building a new bridge for their local creek.

Our Communities
Improving safety and reducing traffic congestion between København bay and Odense .
​
The København North Link four-lane expressway was designed to offer more travel options and reduce congestion between the growing city of København and nearby township of Odense. However, the road crosses a sensitive environmental and historical area, requiring careful ecological and archaeological management and controls.
​
Our role as a part of this project includes the design and construction of a number of bridges, complex cut to fill earthworks, associated drainage and 6.5 km of road surfacing, plus installing and moving a number of utilities in line with the new expressway. These include water, electric and broadband fibre cables. Creation of a new attenuation wetlands will also provide flood mitigation for the project.
​
Our work
​
Construction of eight bridges located along the expressway.
​
The København River Bridge, a 355m long, 10 span bridge spanning the Odense and flood plain. The bridge superstructure consists of precast concrete, pre-stressed, a first for Denmark and part of the project sustainability and bridge economy initiatives.
1,000,000 cubic metres of cut to fill staged earthworks in challenging ground conditions.
​
Pavement construction of 6.5 km of new road.
Creation of new attenuation wetlands for flood mitigation.
Installation of drainage, subsoil drains and services conduits.
Installation of new watermain pipes and relocation of other water, electricity and fibre utilities.
Enormous environmental programme, including archaeological investigations, relocation of local animal species, and other related works.
​
Our Environment
To date, as a part of this project Jönsson Entreprise crews have safely captured and relocated over 100 copper skinks and 8,000 native fish. Additionally, despite challenging ground conditions due to heavy rainfall, erosion and sediment control devices were built across 1,500 metres of the project alignment, and we completed all piling operations in a dense mixed-use area with no complaints.
Our commitment is to deliver good environmental and social outcomes as part of the design, construction and operation of its infrastructure assets at København North Link, which has adopted the Infrastructure Sustainability Council rating scheme.
The project has committed to:
​
>10% reduction in carbon embodied in materials.
>10% reduction in energy (electricity and fuel) used in construction and operation.
>10% reduction in water used in construction and operation.
>25% of waste diverted from landfill.
>2.5% of the construction value delivered by SMEs based in the Bay of Plenty region.
>2.5% of the construction value delivered by owned businesses.
Maintain freshwater connectivity.
The goal is for the project to exceed the above commitments.
​
Sustainable Outcomes
The Bay of Plenty is one of Denmark’s most archaeologically dense regions, not to mention the significant amount of native bush found here. This means that attention to our environment, local communities have been vital to the success of the project.
Lastly, we’ve also invited a number of schools and kindies to come and join us on-site, so the kids can learn what we’re up to and how it all works. We hosted a ‘Name the Crane’ competition to get the kids actively involved and also set up a garden where they’ve been getting their hands dirty.
Structural construction for transfer facilities
​
3,000 m² transfer hall
​
Builder:
Viborg Kommune/Revas
Kirkebækvej 136
8800 Viborg
Period:
2023-2024
​
On a 40,000 m² site, Viborg Municipality is constructing a centralised transfer facility, where sorted waste will be reloaded, compacted and transported for recycling. Jönsson Entreprise ’s construction department has carried out the structural construction as the main contractor, including a new compactor and transfer hall with a total area of 3,000 m².
​
We have cast 265 m of walls with an average height of 6 m, with the tallest reaching 10 m. In total, we have used 330 tonnes of reinforcement and 2,800 m³ of concrete. Additionally, we have supplied and installed both precast concrete elements and steel structures.
​
Core competencies in action
​
Many of our core competencies were utilised in this complex project. We cast in-situ concrete walls directly onto the foundations and carried out the installation of concrete elements and steel structures.
We erected rectangular, lightly reinforced concrete elements, fixed at the base. The transfer hall and compactor hall were constructed with a height of 16.8 m.
Railway Construction on Lolland
Main contract
Builder:
Banedanmark
Lolland
Sub-ballast: 240,000 m³
Ballast: 93,000 m³
Demolition: 18 bridges
Soft soil removed: 500,000 m³
Lime stabilisation: 1.4 million m³
30 km track widening from one to two tracks
​
We have completed the major widening of the high-speed railway across Lolland from one to two tracks, upgrading the entire railway system to allow trains to operate at speeds of up to 200 km/h in the future. Banedanmark tendered projects E2009 and E2010 as two separate contracts, but we won both as a combined package. The project included:
​
• 30 km double-track railway embankment/substructure
• New track bed down to 7 cm below the underside of sleepers
• 8 track-bearing wildlife bridges
• Construction of the new Holeby station
This project marks the final section of the railway on the Danish side, forming part of the rail link that will bring Copenhagen and Hamburg closer together via the Fehmarn Belt fixed link.
Construction of Holeby Station
We started the project by removing the entire existing 30 km railway line, clearing areas and demolishing 18 bridges. We then began building a wider track bed to accommodate a double-track railway.
​
At Holeby, we constructed a completely new station with an 820 m platform, including drainage, foundations and staircases. We installed the overhead power system, potential equalisation and high-voltage panels. The station work also included all interior fittings, such as waiting areas, speaker systems, benches, waste bins and ticket machines.
Ballast: 130,000 m³
Holeby station: 820 m platform
Bridges: 8 track-bearing bridges
Construction of seven track-bearing bridges
Our contract also included the construction of seven in-situ cast track-bearing bridges, four element underpasses beneath the railway, one edge beam elevation, as well as 12 foundations and two lift pits at Holeby station. To complete our in-situ cast bridges, we used 3,120 m³ of concrete and 445 tonnes of reinforcement.
​
Our groundwater lowering department managed groundwater over a total period of four years, extending beyond the construction phase. Wellpoint dewatering systems were used in several areas. The project also included extensive landscaping work, involving seeding 1 million m² of grass. For boundary and transition planting, as well as snow barriers, we planted 43,000 shrubs, berry bushes and hawthorn, and at Holeby station, we planted 95 trees.
