Problems associated with minimum energy design

The engineer in chief of the Country Roads Board directly controls the road and bridge works undertaken by the board, and coordinates and supervises technical aspects of those works undertaken by municipalities to which the board contributes financially. More than 100 bridges are constructed under the board's supervision each year; the majority of these structures are associated with stream crossings, and more than half of them are built by municipalities. In fulfilling its supervisory role with respect to works undertaken by municipalities, as well as in the execution of works under its direct control, the board has the obligation to ensure that the design, construction, and administrative practices associated with those activities are soundly based, and can be shown to be so. The minimum energy concept for the design of culvert and bridge waterways has been investigated in considerable detail by the board's engineers, who conclude that there are such uncertainties in the design procedures and such practical problems in implementation of the concept as to warrant caution in adopting the approach at this stage, and to impose strict limits on its application.
