1. PRY Base - Contents l PRY Support/Base/Platform in the MICE Hall l Requirements l Environment l Design l Structural Integrity l Preparation l Installation l Absorber Change l Schedule l Conclusion Jason Tarrant – Integration Engineering

2. PRY Base - Requirements l Requirements – Load (before cross-bars added) Fix to floor ~25 tonnes (self weight) Overturning Compression Tension NO CAPACITY FOR SIGNIFICANT OVERTURNING FROM MAGNETIC LOAD – This will be taken by the cross-bars, leg ties & link plate connections

3. PRY Base - Environment l Requirements – North side Plate roof on north side Edge of floor / trench Services in trench on wall and ceiling Services trench directly under leg Trench ends False floor

4. PRY Base - Environment l Requirements – South side South mezzanine uprights Services trench Ramp Walkway

5. PRY Base - Environment l Requirements - Services Tracker Cryo South mezzanine Vacuum system

6. PRY Base - Design l TD-1189-2090 - North East Quadrant Existing Base PRY Legs PRY Connector Tie down bars and bases Support Bridge Trench & trench services Trench edge

7. PRY Base - Design l TD-1189-2090 – North West Quadrant Existing Base (shown cutaway) PRY Legs PRY Connector Tie down bars and bases Support Bridge Trench & trench services Trench edge Short columns where raised floor ends Vacuum system (installed later)

8. PRY Base - Design l TD-1189-2090 – South West Quadrant New base / platform PRY Legs PRY Connector Vacuum system Support Bridge Short columns where raised floor ends Tie down bars and bases Brackets and floor anchors

9. PRY Base - Design l TD-1189-2090 – South East Quadrant New base / platform PRY Legs PRY Connector Support Bridge Services trench Brackets and floor anchors Vacuum system South mezzanine supports

10. PRY Base – Structural Integrity l Testing Floor anchor pull out (TD-1189-1922) Component load tests l Analysis & calculation

11. PRY Base - Preparation l South Mezzanine Full length of hinged platforms Raised platforms Reduced leading edge & cut beams Removable section for easy absorber change Fit around PRY

12. PRY Base - Preparation l Trench Water circuit move Ladder move and change North-east tie bars pass between trench services (water and ISIS cables

13. PRY Base - Installation l Bases Floor anchors (TD-1189-2152) Pillars, tie plates & sub-floor (TD-1189-2153) Top plate installation (blue) & hole drilling (TD-1189-2136)

14. PRY Base - Installation l Installation Survey inside bridges into place Add legs & connectors (+ bespoke shims to set position) Add outer bridges Add tie downs / bolt to floor

15. PRY Base – Absorber Change Absorber change

16. PRY Base – Schedule l Schedule Prep for frame by July 2014, PRY install by end Aug 2014

17. Conclusion l Design done (top level = TD-1189-2152,2153,2136 & 2090) l Calculation and analysis shows OK for self weight only (not magnetic load) in terms of stress and strain l Piece parts out for manufacturing quotation l South mezzanine structural engineering drawings near completion (OPUS) l RFS placed for floor quality tests l Load testing on critical parts will be undertaken l Possibility of strain gauges on critical parts as per main PRY (H Witte investigating) l Schedule currently predicting manufacture, prep and install to coincide with PRY delivery (final install dependant on PRY frame delivery)
