SUSPENSION POSITIONING Some significant cyclones which Mozambique in the past include: have hit a) Dando in the year 2012 BRIDGE´S DECK LIFTING AND Lifting and positioning was done with the assistance of two separate sets of cables. They were supported at the pylons. On these two cables a crane was suspended with the ability to move vertically and perform a 90° vertical axis rotation. 57 deck segments were lifted and positioned over the waterway section of the bay. Seagoing Vessels then brought the 12m long and up to 150t deck segments one by one, each segment was lifted and before the crane approaches the final design elevation it rotates 90° and brought the segment to its final position. Each steel segment had a depth of 3m and a width of 25.6m. b) Leon-Eline in the year 2000 c) Domoina in the year 1984 SUMMARY Despite the fact that the main span of the Suspension Bridge is only 680m and it is much shorter than the longest suspension bridges in the world such as the Xihoumen Bridge in China which is 1,650m (2 nd longest) and the Akashi Kaikyo Bridge in Japan which is the longest span at 1991m, this Bridge brings Mozambique and the whole continent of Africa into the engineering community with the use of an advanced level of technology with regards to bridge construction, demonstrating the significant ambition and achievement of a historically unprogressive, poverty-stricken African state. ACKNOWLEDGEMENT That this type of suspension bridge in Maputo - Katembe, Mozambique was feasible to design is thanks to a handful of international experts worldwide with this special knowledge. Cyclones in the South West Indian Ocean for the period 2013 – 2014: From the Chinese Construction Company CRBC the main contribution was provided by Design Leader Mr. Cai Jingwang. From the Mozambican Authorities (Maputo Sul) Mr. Vicente Miranda was instructive and supportive for the Design Team and later also Mr. Basilio Nzunga. My honour was to be the Consultant, at the head of the above Design Team supported by my Greek Office Team (INSTAT SA), especially Mr. Dr.-Ing. Aristoteles Kakaliagkos. The orange points are wind speeds up to 350 km/h. Finally, I want to thank GAUFF Nurnberg, especially Mr. Stefan Tavares Bollow and Mr. Bernhard Streit for giving me the opportunity to participate in this impressive project. 1/2019
