In the reforms of the RICS in the 1990s, the former divisional structure of the institution was abolished and the use of the alternative designations retained solely for the use of members to retain clarification when informing clients of specialist areas of expertise. Despite the attempt to unify the profession under one title chartered surveyor there is very little in common across the whole range of disciplines that are within the grasp of all members. The core membership is based in the construction profession, and another large sector deal with property ownership and management. Beyond these cores there are marine, land, rural and antiques specialists.
