Mais sobre a Ponte 4 de Abril
The 4 de Abril Bridge, designed by engineers Armando Rito and Pedro Cabral, involved 14,900m3 of concrete, 591,000 kg of prestressing steel and 1,700,000 kg of passive steel and is characterised both by the innovation of the techniques used and the planning and execution of the work on site. The two "U" shaped towers of the 4 de Abril Bridge stand out for their transparency due to the absence of bracing.
This work of art is a contribution to local reconstruction that will benefit the community and promote the union between the adjoining cities of Benguela and Lobito.
For the first time in the Secil Civil Engineering Awards history, this prize is awarded to a pair of engineers. The award-winning engineer Armando Rito states that "this is, in fact, an important milestone in the history of the Secil Civil Engineering Awards because, for the first time, it is awarded to a project on the African continent, an example of the internationalisation of our engineering and with particular emotional significance as it is located in a CPLP country". And he adds that "I am very proud that this prize has been awarded to a project of mine and of engineer Pedro Cabral, who contributed a great deal to the execution of this project of undeniable value for the development of the Benguela Province".
