The challenge was to design a pair of 27 metre high towers, which could provide temporary support at the mid-span of the 56 metre wide parabolic structure. As the acknowledged innovator in the field, RMD Kwikform made full use of its experience to carry out the structural analysis and risk assessment, while utilising both standard and specially engineered components to meet the multiple demands.
The solution to the project brief was developed in partnership with the client over a period of months with RMD Kwikform engineers attending meetings with the clients in Germany, France and Morocco. Once the final configuration had been confirmed, bespoke equipment was manufactured and the equipment erection phase of the project began onsite in June of 2012. This phase of the project was supported by two of the RMD Kwikform’s site specialists, who trained and supported the erection teams onsite at Jorf Lasfar.
Perhaps of greatest significance to the client, SOGEA was the fact that the RMD Kwikform solution avoided the onerous task of erecting conventional scaffolding down the entire centreline to the hangar, saving both time and money. Instead the two linked towers, with an overall footprint of 13.3 x 5.14 metres are mounted onto rails that enable them to be moved from the line of one structural rib to the next. When the project is complete, the shoring can be dismantled for reuse on other sites.
Whilst the majority of the towers are assembled using RMD Kwikform’s standard Megashor heavy-duty shoring system, the top and bottom sections were bespoke engineered and fabricated specifically for the task. These sections provide both stability, mobility and a highly accurate mounting point where the ends of the 1.6 tonne precast members could be positioned before the engineers made the permanent connections between them.
