IADC is dedicated to not only promoting the skills, integrity and reliability of its members, but also the dredging industry in general. IADC has over one hundred main and associated members. Together they represent the forefront of the dredging industry.

IADC Public Relations Committee

The committee meets four times a year in various venues and members are on-call in between for consultation. They contribute ideas for the IADC to further its PR activities, including providing lecturers for IADC seminars and advising about articles for Terra et Aqua Journal, the Facts About series and other IADC publications.

IADC Legal Committee

In 1999, FIDIC published new standard forms of contract but this new work did not meet the specific needs of dredging and reclamation work. The IADC contacted FIDIC about the possibility of a separate FIDIC dredging contract. A Task Group was formed and produced the FIDIC Form of Contract for Dredging and Reclamation Works. Since then, the Legal Committee has periodically helped to update the FIDIC document for dredging.

Safety Committee
