The pre-evaluation process is explained under the rules and regulations (paragraph 5):
The pre-evaluation committee looks through each application and decides which teams will qualify for the final competition. The decision is based on three criteria:
1. Safety of the bridge
2. Compliance with competition rules
3. Originality/aesthetics of the bridge (If there are more than 15 applications
and all the proposed bridges fulfil the 1. and 2. criteria)
Altogether, 9 teams sent their applications before the deadline (01.02.2016 21:00 CET) and since they all met all three criteria, we were happy to announce that they all qualified for the final competition.
