The enlargement of Copenhagen’s Nordhavn (North Harbour) includes a new cruise-ship terminal and the reclamation of 100 hectares of land. The project was carried out in an area with particularly complex sedimentation conditions and the repository for contaminated soil is governed by strict environmental regulations. Sweco served as a client consultant and was responsible for the Environmental Impact Assessment (EIA).
Task: Cruise-ship terminal and land reclamation
Customer: By og Havn I/S
Period: 2010–2014, EIA: 2008–2011
Capital expenditure: DKK 1,000,000,000
Other consultants: DHI, Hasløv and Kjærsgaard
Expertise: Client consultancy, EIA report and environmental assessment
The enlargement of Copenhagen’s North Harbour comprises a cruise-ship terminal 1,100 m in length, a repository for clean and contaminated soil, 2 km of access roads, administration buildings, terminal buildings and a 500-metre-long quay wall which is prepared for a future container terminal.
Sweco served as a client consultant for By & Havn and carried out geotechnical surveys and design work. Sweco has also prepared an EIA report for a double sheet-pile wall 1,200 metres long for a deep-water quay, the dredging of the fairway and land reclamation of 100 hectares, of which 50 hectares is a repository for contaminated soil.
The project was carried out in the northern section of the Port of Copenhagen, an area with particularly complex sedimentation conditions. The land reclamation repository has a capacity for 10 million m3 of soil, 6 million m3 of which is contaminated. This means that the repository is subject to strict environmental regulations.
The cruise-ship terminal is 1,100 metres long and 70 metres wide and will serve some 60% of incoming cruise-ship traffic to Copenhagen – or roughly 200 ships a year. The terminal is constructed with both a conventional sheet-pile wall and a double sheet-pile wall. The fairway has been deepened to create sufficient water depth and the EIA report focused on the impact of sedimentation dynamics, water quality, aquatic and terrestrial flora and fauna, navigational safety, traffic, air pollution, noise and landscape conditions.
As the party responsible for the environmental assessment, Sweco contributed preliminary project work, geotechnical surveys, geological and hydrogeological modelling, specification of maritime studies, an EIA report, regulatory coordination, regulatory approval, registration of flora and fauna, an archaeological maritime study, a calculation of traffic-related air pollution and a monitoring programme.
As client consultant, Sweco contributed capital expenditure estimates, assisted in preparing calls for contractor tenders and contracting, supervision and construction management, handover ceremony, investigation of raw-material resources, configuration of a dredging site, project coordination, safety coordination, environmental coordination, specification of requirements for a cruise-ship terminal and terminal area, construction management and prepared calls for tender for detailed design engineering and contract works.
