Naturkatastrophen und Kriegsereignisse zerstören häufig wichtige Landverbindungen. Die Emergency Bridge passt in einen Schiffscontainer. Das besondere: es muss nur ein Ufer zugänglich sein. Denn zum Erreichen des anderen fehlt die Brücke.
The Emergency Bridge solves a complex set of problems with a pragmatic sequential response. The design, executed in just a few days, addresses an array of challenges including socio-economic issues, topographic and geographic conditions, dimensional constraints [maximal compaction and expansion] and the inversion/reversion of structural forces in each cycle.
The constructional phases of any project are always merely a means to an end but in this case the cyclical pattern of temporary and permanent conditions requires a clarity and simplicity which the proposal illustrates with relative ease. From this perspective it is also has a beauty: light, legible and free of contrivance . It is, or could become a very viable proposition that deserves continued investigation.
It occurs to me, after the event, that a limiting factor to that viability may be a lack of flexibility in the span configuration which could be simply resolved by any unextended length contributing to the counterbalance during mobilisation. The variable span would secure the applicability of the standard unit.
The workshop required, for ease of identification, a »tag« for each proposal. In reality the »Emergency Bridge« is undersold since the result is fit for various social commercial and aesthetic as well as humanitarian emergencies.

The proposed pedestrian bridge spans 60m and is capable of carrying the imposed life load of the biggest known pack animals: elephants. The folded package fits exactly into the outer dimension of a 40´ standard shipping container. By doing that it utilizes a global existing transport system to be delivered in time to the right place providing infrastructure and help for those who are in need.
Arrived at its destination the folded truss beam is assembled on landside providing sufficient working space. Folded and linked tetraeders are simply slide out by hand and put together by inserting a sectionized upper cord. With water tanks as counterweight the beam is turned over the actual barrier on an integrated turntable. After that an additional suspension is brought in increasing the structural height of the construction. Last step of the erection process is the assembly of the floor plates and the balustrade which consists out of a simple but light weight nylon mesh.
In case of natural or human disasters the EMCBridge provides first aid to geographical regions that are in need of supply or simply reconnects locations by providing the Infrastructure. Key requirements have been cantilever erection from one side, erectable by one technician with a handful of unlearned local people and without use of additional machines.
With fast response the bridge will reconnect communities and supply chains bringing help to those who are in need.
