Work Detail

Architectural, Construction, Engineering And Inspection Services – Engineering Services General Planning For The Foundation Renovation Hans Eisler University Of Music - Id24183ge. With The Construction Of The Replacement Building For The Town Hall Bridge, Damage In The Form Of Cracks And Settlements Occurred In The Corner Of The Schlossplatz/Spree Building Of The New Marstall (Hans Eisler University Of Music). This Results In Latent Instability Of The Building, Which Requires Renovation Both At The Foundation Level And In The Building Construction. As A Result Of Initial Investigations, Significant Deficits Were Identified, Particularly Along The Outer Wall On The Spree Side, With Regard To The Formation Of The Foundations In The Context Of The Existing Boundary Conditions (Spree Bed, Bank Protection). Due To The Complex Situation, The Construction Site Facilities Are Also Important. In Addition, Extensive Coordination Must Be Carried Out With Various Authorities, Including The Water Authority. The Building Is Founded Flat As A Strip Foundation And With Point Foundations. Deviating From This, The Stable Wall On The Spree Side Extends To 4 M Below The Groundwater Or Spree Level With An Upstream Wooden Sheet Pile Wall Scour Protection On The Spree Bed. However, There Are Deficits With Regard To The Strength Of The Foundation Structures/Building Structures And The Overall Foundation Situation During Construction. It Cannot Be Assumed That The Historic Bank Fortifications In Front Are In A Sufficiently Good Structural Condition To Support The Loads On The Higher-Lying Foundation Of The Stables. Both The Historical Plateau And The Newly Placed Town Hall Bridge Plateau In Front Of It Create Additional Stability In The Outer Wall Of The Stables, Which, However, Cannot Compensate For The Deficit Of The Different Foundation Levels. However, The Scour Protection Is No Longer Intact. Diver Results Are Available. Both The Deficits Identified In The Foundation Area Of ​​The Spree-Side Wall And In The Connecting Area Of ​​The Street-Side Wall As Well As The Planned Foundation Level At The Level Of The Spree Bottom, The Resulting Insufficient Embedding Of The Water-Side Foundations Combined With The Very Low Strength Of The Backfill Concrete And Damage To The Scour Protection Sheet Pile Wall, Lead To Major Deformation. /Subsidence Potential. In This Context, Any Changes In The Embedding Situation, Load Changes From Renovations, Larger Groundwater Fluctuations, As Well As Any Dynamic Influences From Traffic Or Neighboring Vibration-Simulating Work Have Already And Will Lead To Further Settlement In The Future. In Order To Eliminate These Potential Threats To Stability And To Ensure That The Building Can Be Used With Minimal Settlement, Additional Foundation Bodies Would Have To Be Constructed Beneath The Spree-Side Wall And In The Transition Area Of ​​The Street-Side Wall. In Connection With Undetectable Scour Protection, Technologies/Procedures That Minimize The Temporary Loss Of Stability Due To Execution Must Be Used In This Area. In Order To Provide A Well-Founded And Long-Term Effective Upgrade Of The Outer Wall Of The Stables On The Spree Side
