The bell-pier scheme of construction is being increas-ingly used for major bridge piers in deep water. This scheme has undergone considerable evolution and improvement in recent years, with better utilization of precast concrete shells, better control and quality for tremie concrete, and improved details which have greatly reduced the amount and complexity of underwater connections. This recent experience portends further developments and use. A number of these trends and potential improvements are suggested for consideration.
