PRY Support/Base/Platform in the MICE Hall Requirements Environment Design Structural Integrity Preparation Installation Absorber Change Schedule Conclusion
Jason Tarrant – Integration Engineering
PRY Base - Requirements 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
PRY Base - Environment 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
PRY Base - Environment Requirements
– South side
South mezzanine
uprights
Services trench
Ramp
Walkway

PRY Base – Structural Integrity Testing
Floor anchor pull out (TD-1189-1922)
Component load tests
Analysis & calculation
PRY Base - Preparation South Mezzanine
Full length of hinged platforms
Raised platformsReduced
leading edge & cut beams
Removable section for easy absorber change
Fit around PRY
PRY Base - Preparation Trench
Water circuit move
Ladder move and change
North-east tie bars pass between trench services (water and
ISIS cables
PRY Base - Installation Bases
Floor anchors (TD-1189-2152) Pillars, tie plates & sub-floor (TD-1189-2153)
Top plate installation (blue)
& hole drilling (TD-1189-2136)
PRY Base - Installation Installation
Survey inside bridges into place Add legs & connectors(+ bespoke shims to set position)
Add outer bridges
Add tie downs / bolt to floor
PRY Base – Absorber Change Absorber change
PRY Base – Schedule Schedule
Prep for frame by July 2014, PRY install by end Aug 2014
Conclusion Design done (top level = TD-1189-2152,2153,2136 & 2090) Calculation and analysis shows OK for self weight only (not
magnetic load) in terms of stress and strain Piece parts out for manufacturing quotation South mezzanine structural engineering drawings near
completion (OPUS) RFS placed for floor quality tests Load testing on critical parts will be undertaken Possibility of strain gauges on critical parts as per main PRY (H
Witte investigating) Schedule currently predicting manufacture, prep and install to
coincide with PRY delivery (final install dependant on PRY frame delivery)
