2008 Event

 

 

The Task was based on designing and building a bridge across an estuary. Part of roadway had to be raised using a controlling device that had to be part of The design. When raised, the clearance had to be sufficient to allow the passage of a "tall ship" (HMS Rotary). This portion had to be lowered. The bridge had to strong enough to allow a 1kg weight to be dragged across both before and after raising. The clearance of the unraised bridge had to be such that a barge could pass underneath at all times.

 

The Basic task required just one spar to be raised.

The Intermediate task required two to be raised but a central support was available "mid-stream".

The Advanced task also required both spars to be raised but no central support was available.
