Work Detail

Architectural, Construction, Engineering And Inspection Services – Fachplanung Monitoring. The Subject Of This Award Procedure Are Specialist Planning Services For The Monitoring Of The Bw 40/12 Lipowskybrücke Road Bridge In Munich. The Lipowsky Bridge Carries Radlkoferstrasse Over The Deutsche Bahn Tracks, Which Connect Munich Central Station With Ostbahnhof. The Structure Was Built In 1963/1964 As A Single-Span Prestressed Concrete Slab Bridge And Was Designed With Longitudinal And Transverse Prestressed Tendons Made Of Sigma Oval Prestressing Steel. Due To The Use Of Prestressing Steel From Older Generations That Is At Risk Of Stress Corrosion Cracking, As Well As An Announcement Behavior That Has Not Been Adequately Proven Mathematically, The Structure Is Classified As At Risk Despite Its Overall Good Structural Condition. Prestressing Steel Fractures Can Occur Without Any Visible External Signs And Represent A Particular Risk For The Continued Operation Of The Building. A New Replacement For The Structure Is Planned, But The Date Of Implementation Has Not Yet Been Determined. To Ensure Safe Continued Operation Until The Replacement Building Is Completed, The Introduction Of A Qualified, Building-Specific Monitoring System Is Planned. The Aim Of Monitoring Is, In Particular, The Early Detection And Localization Of Possible Prestressing Steel Fractures As Well As The Continuous Assessment Of The Structural Condition Of The Building. The Measurement Data Obtained Serves As A Basis For Reliable Engineering Decisions Within The Framework Of Building Management And Contributes To Ensuring The Safety Of The Building. The Subject Of The Procurement Is The Performance Of A Specialist Monitoring Planner Based On The Dbv Leaflet On Bridge Monitoring. The Specialist Planner Takes Over The Technical Conception, Planning And Support Of The Monitoring Measures Throughout The Entire Duration Of The Monitoring. In Addition, He Is Involved In The Preparation And Technical Support Of The Award Procedure For Commissioning A Specialized Service Provider For Structural Measurements And Supports The Client During The Implementation And Operation Of The Monitoring. The Scope Of Services Includes In Particular: - The Recalculation And Engineering Evaluation Of The Bridge Structure, - The Creation Of A Monitoring Concept Including The Determination Of Suitable Measured Variables, Measuring Points And Limit Values, - The Preparation And Technical Participation In The Awarding Of The Implementation Planning And Implementation Of The Monitoring, - The Support Of The Implementation Planning Of The Measuring System, - The Support Of The Installation, Commissioning And Operation Of The Monitoring, - As Well As The Ongoing Evaluation And Evaluation Of The Measurement Results. As Part Of The Monitoring, At Least One Sound Emission Monitor And Another Independent Monitoring System (E.G. Fiber Optic) Must Be Provided. In Addition, Video Surveillance Of The Structure Must Be Planned. The Monitoring, Installation And Operating Concepts Must Be Developed Taking Into Account The Special Boundary Conditions Of The Structure
