oa Civil Engineering = Siviele Ingenieurswese - Temporary emergency train-carrying bridges
Transnet Freight Rail (TFR) experiences destruction or loss of its permanent train-carrying bridge decks during severe weather conditions, and derailment of trains. Consequently, train lines are out of service until such time that permanent decks are repaired or temporary decks placed, resulting in a loss of revenue. TFR's previous temporary emergency bridge decks were not of a modular-type design, resulting in time-consuming and costly preparations to accommodate the fixed-length temporary emergency bridge decks. TFR needed to procure temporary bridge decks which are designed to be assembled, taken apart and reused during fabrication/construction of the permanent structure. Temporary bridge decks can be erected relatively quickly, thus allowing less out-of-service time. When permanent decks are eventually replaced, the temporary ones can be used elsewhere. The project entailed the full scope of design, shop-detailing, fabrication, painting, quality control and delivery of temporary bridge deck components to TFR's yard in Sentrarand, Gauteng.
