DAAB is not a formal waiting room before arbitration. In the 2017 FIDIC editions the emphasis moved toward dispute avoidance: the board should help the project avoid a full dispute where possible.

When DAAB matters most

DAAB is critical where the project is live, the programme is complex, Engineer’s determinations are active, claims are accumulating and work stoppage is a risk. The earlier the board is appointed, the better the chance of solving issues before arbitration.

What to prepare

A position needs the contractual basis, chronology, notices, records, programme, calculation and link to the Engineer’s determination. Without this, DAAB becomes expensive correspondence.
