Causeway at Jubail Industrial City with His Majesty King Fahd’s SEA PORT (1981)
The works included three big bridges (two over 425m in length and over 140m in length) some as prestressed box girders and some as precast post tensioned beams. Deep piles for abutments and huge retaining walls of 12m high with associated buttresses were also part of the works. Said bridges had to pass over high pressure hydrogen sulfide gas pipelines and overpassed two seawater canals of 60m wide, a case which posed a big challenge in construction. Super elevated box girders 2.4m high and 17m wide with free spans up to 60m in length were built. Said bridges received three sequences of post tensioning. On different spans over a hundred fifty precast post-tensioned beams up to 38m in length and 90 metric tonnes in weight, each, had to be installed under very adverse conditions, location wise and schedule wise. On said bridges SOMAC prestressing engineers and teams carried over six hundred prestressing operations implementing the design criteria with high accuracy and superlative professionalism. SOMAC has dealt with the three world authorities on Bridges namely T.Y.Lin, VSL Losinger and James Libby.
