The various task were properly defined by ODA, what was to be achieved, time of completion of different
sections and setting up of the different control measures to enable success.
• Implementation – pylon removal, cabling and equipping, tunnelling
and substation construction.
• Handover of assets and the close out of the project:
At this stage the project was tested the underground power line was switched on and confirmed working
• Completion and close of the project: project review
5. Challenges posed by plug
• Change of client from LDA to Olympic delivering authority
• The high number of stakeholders
• Limited time
• It required a large number of approvals
• Technical challenges
7. KEY DECISIONS THAT LED TO SUCCESS
• Changing the hierarchy of the project organisation and governance
