Hyder became ‘Preferred Bidder’ for one line of the Riyadh Metro tender, which I produced the design programme. Having achieved this status, I was required to provide significant amendments and additional details to the integrated design programme to match the set dates for construction tasks. This was to define by what dates each station required to have the completed designs to remain on time. To do this I was required to determine which aspects of the design needed to be completed prior to the construction tasks.
