Creativity, experience and environmental awareness make a good team when it comes to bringing former port or industrial sites back to life.

Filthy properties,..... we just love them!

Since its foundation in 2000, imetas has become a specialist for contaminated conversion sites.

Profound know how about all phases of the complex processes of such developments, from acquisition, legal evaluations incl. post liability, financial feasibility, management of authorities, public law contracts up to the implementation of technical processes for cleaning or disposal of contaminated soils are part of our expertise.

Through our extensive experience, we are capable to repair the soil in an environmentally friendly manner, creating potentially new habitats for humans, animals, plants and groundwater.

In cooperation with Geobality Canada Inc. ( we are able to solve even difficult contaminations with biological methods.

Successfully remediating contaminated land means, above all, involving the people with their knowledge, experience, concerns and ideas for new ways.

What we do in Canada

In British Columbia we will successfully continue what we have started in Europe.
Acquisition of suitable contaminated land in unique locations
-  Finding the genius loci of the location
-  Working out the appropriate framework conditions in cooperation with all        relevant authorities, neighbors and affected First Nations
-  Developing the urban planning concept and architecture

-  Active implementation of sustainable development goals (SDG)

Bio-Remediation of contaminated sites
Realization of the projects in partnerships with other companies

Military Base Kiel, Germany

  Project:                   Fördeterrassen

  History:                  Part of former Marine-Airforce base.

  Size:                        ~ 60,000 sqm

  Zoning:                   Special use military area.

  Neighbourhood:  Port area with transshipment quays, Customs port and entrance to Kiel-Channel                                    one of the most used waterways on earth.

  Contaminates:      Soil: Hydro carbons,

                                     Buildings: Polluted materials with Bitume, PAH and Phenole.

  Specialties:            imetas acquired the site from the government of Germany.  Soil artificially filled                                       in the fjord. The area was always used as a military base.  The neighborhood is                                       interfering with the operational readiness. Noise and exhaust emissions from                                           ships pollute the area.


  Rezoning:                 An urban architectural contest initiated by us laid the foundations for a future                                              mixed-use development. The area of 60,000 sqm was divided into 4 different                                              building areas with different building typologies. Approx. 10,000 sqm have been                                        set aside as biotope forest and approx. 8,000 sqm for roads and paths.                    

                                     - The largest construction field B with approx. 15,000 sqm was developed and                                               build on by imetas. The remaining construction fields were sold to investors                                                 with building rights for 126 units and development.                                

                                     - In two construction phases on B 9 buildings with a total of 93 apartments and                                             117 underground parking spaces were built.

                                     - The heat supply is provided by geothermal heat pumps and solar thermal or                                               photovoltaics by imetaplan as contractor.

                                     - Noise protection windows and sea-weather resistant materials are used                                                       throughout the quarter.

  Contaminates:         Soil: Dig and dump. Soil excavation for underground garages.

.                                     Buildings:  Demolition, separation of the loaded material and crushing of the                                               clean material as fill material for paths.

  Construction:           ~570  pile foundations with 15 m length. Of these, approximately 130 are                                                         combined energy piles for the geothermal probes.

Harbour site Hamburg, Germany

  Project:                   Oval und Kontor am Kaiserkai

  History:                  Former warehouses and ship equipment dealer.

  Size:                        ~ 2,500 sqm

  Zoning:                   Special use port area.

  Neighbourhood:   Port area with transshipment quays and Customs port.

  Contaminates:      Soil: Hydro carbons,

  Specialties:            Rotten wood pile construction of former docks.                                                                                           -  Hafencity Hamburg is Europe's largest cohesive development project within a                                    single city. Politically desired, the development of the entire area was prepared                                      by the city. Infrastructure and flood protection was produced by the city.                                                   The lands old buildings were cleared and sold by the city.


  Rezoning:               The city has created the general building law for residential and work spaces. In                                     a further process, we were able to negotiate deviations from the urban plan-                                    ing specifications  in relation to our planning.This resulted in the 11-story  "Oval                                        am Kaiserkai", the only high-rise in the area.

                                   With 6 stories, the "Kontor am Kaiserkai" complies with the city's specifications.                                       Building permit with many conditions for flood and noise protection.

  Contaminates:      Soil:  Dig and dump. Complete 2.5m depth soil exchange.    

  Construction:        85 bored pile foundations with 22m length. Due to the old piles in the ground                                        partly set by tests. Restoration of the old quay foundation. Flood protection for                                    the 2 underground garage floors.

  Zoning:                   Special use muncipality use.

  Neighbourhood:  closed to the historic UNESCO World-Heritage city center of Lübeck.

                                   Direct neigbourhood with mixture used residential + commercial + public park                                            alongside the river shoreline

  Contaminates:      Soil and groundwater: Hydro carbons, heavy metals

                                     Buildings: Polluted materials with Asbestos, Bitume, PAH and Phenole.

  Specialties:            Acquisition after Europe-wide bidding. Due to the heavy contamination, only a few                                    participants were willing to bear these risks.


  Rezoning:                Elaborate remediation concept in which the seller, the city and the project                                                   company assumed obligations. This 3-party agreement is a prime example of a                                         good PPP model for making sense of urban development even in complex                                                 situations.

                                    An urban architectural contest initiated by us laid the foundations for a future                                             mixed-use development. The area of ~28,000 sqm was divided into 2 different                                           new building areas with different building typologies and about 100 units                                                     between the existing old office buildings.        

                                     - A campus concept with commerce, education and apartments was created.
                                     - The old office buildings were partially refurbished, newly leased and then sold.
                                     - In the first construction phase, imetas & Partner produced 4 buildings with 48                                            condominiums.

                                     - The second construction phase was sold with building permission.                        

  Contaminates:         Soil:  Phase 1:  Dig and dump. Soil excavation for underground garages.

                                               Phase 2: Cover with sheeting and separating layers, degassing shafts and                                                    tree troughs, and backfill with clean soil.

                                      Groundwater: Sealing wall to divert groundwater to drain contaminated area as                                         an obligation of the seller.

                                      Buildings:  Disposal of the contaminated material during the remediation work.

  Construction:           Phase 1: ~140  pile foundations with 15 m length.  Flood protection for                                       the underground garage.

Water Work, Lübeck, Germany

  Project:                   Wasserkunst

  History:                  Former muncipality water work plant

  Size:                        ~ 38,000 sqm with an old heritage workshop

  Zoning:                   Special use muncipality and protected landscape area

  Neighbourhood:   The property is located on the banks of the river Wakenitz in a popular villa dis-                                        trict in Lübeck. A heritage Water Tower from 1871 stands directly beside the site.

                                   Direct neigbourhood with mixture used residential + commercial + public park                                            alongside the river shoreline

  Contaminates:      Soil and groundwater:  Old waterworks cleaned the water in large multi-stage                                          filter basins before discharging it into the public supply. The filtered-out  pol-                                             lutants, including hydrocarbons, phosphates and heavy metals, settled in the soil.

  Specialties:            Acquisition after Europe-wide bidding. Due to the complicated procurement of                                         building rights from the protected landscape area and the contamination, only a                                       few participants were willing to bear the risks. Resistance to the project was                                               evident from the outset on the part of environmental associations and politicians.


  Rezoning:                Since large parts of the site were designated as a landscape conservation area                                          with a riverbank biotope, reliable time schedules for realization could not be                                                established. imetas acquired the site in partnership with Primus.

                                    An urban planning competition initiated by our partners and us laid the                                                        foundation  for a future mixed-use development. The site of ~38,000 sqm was                                            divided into several new development areas with different 28 buildings and                                                approx. 240 resdential units.        

                                   - A quarters concept with apartments, townhouses and individual houses was                                              created. The integration into the villa-like surroundings, the historic water tower                                          and under preservation of large areas of the previous landscape conservation                                            area with public hiking trails were several challenges.
                                    - The old filter hall of the waterworks was to be integrated and converted into a                                           water art museum.
                                    - The previous landscape conservation area was partially de-designated. The                                               direct shore area continues to be biotope.   

  Contaminations:     Soil: excavation and landfill. Excavated soil for underground parking.

                                     Buildings:  Disposal of contaminated material during remediation work.

  Construction:          Topographic offsets of more than 9m in places with varying soil qualities.

  Project duration:    5 years for imetas. The entire process to achieve building rights took almost 7                                             years. imetas sold its shares to a developer company.

Fish-Harbour Hamburg, Germany

  Project:                   Dock Island

  History:                  Former Fish-Harbour, out of duty for 30 years.

  Size:                        ~ 30,000 sqm

  Zoning:                   Special use sea-harbour, attached to an international water way.

  Neighbourhood: The property is located directly on the banks of the Elbe River in a popular                                                    Hamburg neighborhood. The world-famous Hamburg fish market is an integral                                          part of the party scene and tourism activities. Direct neighborhood with offices +                                          commercial uses + a cruise center + restaurants and pubs along the river bank.

  Contaminates:     Port sludge polluted for decades with industrial contamination and sediment                                              settling. Heavy metals, hydrocarbons such as PAHs.

  Specialties:          The proposed project will require dredging of the harbor basin. Remediation of the                                   sludge to reduce final disposal costs is an important economic factor in this project. 
                                   Due to the Covid-19 measures, the event project has been put on hold for now                                         until planning certainty returns.
