SUMMARY:Real-Time Monitoring to Inform the Construction of Large-Diameter 
 Caissons - Dr. Brian Sheil\, RAEng Research Fellow\, University of Oxford

DESCRIPTION:Large-diameter reinforced concrete caissons are a widely-adopt
 ed solution for underground storage and attenuation tanks\, and launch and
  reception shafts for tunnel boring machines. The sinking process presents
  a number of challenges including maintaining verticality of the caisson\,
  controlling the rate of sinking\, and minimising soil-structure frictiona
 l stresses through the use of lubricating fluids. A bespoke monitoring sys
 tem has been developed at University of Oxford to provide early warning of
  adverse responses during the sinking phase (e.g. excessive soil-structure
  interface friction). The monitoring system was trialled on a recent pilot
  project in the UK involving the construction of a 32 m internal diameter\
 , 20 m deep reinforced concrete caisson. This seminar will describe the mo
 nitoring system that was developed and its impact on the construction proc
 ess of the pilot project. The potential role of machine learning algorithm
 s in construction monitoring will also be explored.
