The articles below are grouped by the decisions, controls and risks they address rather than by publication date.
Why extension of time, prolongation cost and disruption are related but distinct analyses requiring chronology, programme evidence, causation and separate cost substantiation.
FIDIC contracts can be amended, but the Golden Principles explain why changing roles, risk balance, time periods or dispute mechanisms too aggressively can leave only the FIDIC label behind.
The 28-day notice is a serious FIDIC time bar, but the 2017 procedure contains important notice, deemed-validity and late-submission mechanisms that are often misunderstood.
How event registers, notices, site records, correspondence, photographs, resource records and programme updates create defensible evidence for time and cost entitlement.
