The prosperous years of the 70’s followed by the lean years of 80’s and 90’s saw a series of acquisitions and consolidations in the industry resulting in both changes of name and the disappearance of many company names.

The Secretariat remained with Hogg Bullimore in the City of London but moved in the 70’s to Chile House, Ropemaker Street until they became part of the Alliott Group based in Kingsway.

Chairmanship of the Federation was an honoured responsibility bestowed in strict company rotation. With membership of 12 or 14 companies the opportunity of chairmanship gave a respected position in the industry for many years.

Historically the Federation embarked on significant contractual guidance and legislative issues, for example specific Conditions of Contract (a Blue Book based on ICE 4th of the time) were drawn up to address Dredging and Reclamation works. 

We have always been consulted by Government on new legislation and have been recognised as our industry’s voice in consultation.

We have maintained good relationships with Government bodies, Port Authorities, Private industry and Environmental groups, associated with the Marine, Port and Coastal Sectors. 

We have provided a forum to meet industrial peers and discuss issues of mutual importance.
