This is a demonstration of converting FIDICcharts from a horizontal swimlane approach to a vertical drop-down approach. It is based on a d3.js collapsable indented tree. FIDIC Civil Works 3rd Edition (1977) contract clauses are mapped as flowcharts using clause statement summaries ( blue rectangles) with "+" to open clause statements, questions ( green rectangles with rounded corners), inline process statements (open rectangles), and notes (open circles giving open rectangles with rounded corners). Process statements are opened via small open rectangles above clause and inline process statements. The flowcharting convention is standard and essentially follows A new approach to the International Civil Engineering Contract by G.P. Jones. The red timeline in the chart for Clauses 3/4 is for demonstration purposes. Info.
