Tenders Are Invited For Construction Work – Bergedorf Innovation Park - Elevation Of The Terrain

Construction Work – Bergedorf Innovation Park - Elevation Of The Terrain. Creation Of A Sand Embankment Installed In Layers With A Slope Gradient Of 1:2 Up To The Target Terrain Height According To The B Plan, Supplemented In Sections By Vertical Drainage And Horizontal Geotextile Reinforcement To Accelerate Settlement And Ensure Stability. The Aim Is To Consolidate The Soft Soils And Create A Usable Sand Subsoil For Handover To The Subsequent Trades. In The Area Of ​​The Later Traffic Areas, The Normal Fill Will Be Supplemented By An Overload Fill To Anticipate The Traffic Loads. The Measure Covers Two Consecutive Construction Sites, Each With A Duration Of Approximately One Year. To Ensure Suitability For Use, It Must Be Proven That The Residual Settlements Are Less Than 4 Cm Or That A Degree Of Consolidation Of At Least 95% Is Achieved When The Areas Are Handed Over. The Decisive Boundary Conditions For The Implementation Are The Settlement-Sensitive Holocene Soft Layers, The Location In Water Protection Zone Iii Of The Curslack/Altengamme Water Protection Area And The Adjacent Existing Uses, In Particular The Körber Technology Campus. In Order To Carry Out The Construction Work, Construction-Related Drainage In The Form Of Horizontal Drainage, Collecting Pipes And Temporary Pump Sumps Is Required. In Addition, A Multi-Stage Water Treatment System Must Be Used. The Treated Pore Water Is Reintroduced Into The Receiving Water Of The Northern Motorway Ditch.
