The New Skuru Bridge was proposed to assist the existing Old Skuru Bridge (which handles52000 cars daily) manage the growing volume of vehicles. Investigations show that by 2030,the bridge will need to handle excesses of 85,000 vehicles a day. During the New SkuruBridge design and construction, the contractor found that the design and construction ofabutment 01 were challenging, expensive, and time-consuming. The project aimed todetermine whether the composite deck abutment design was more feasible, cost-effective, andenvironmentally friendly than the concrete cast-in-place abutment.The central focus of the study is to explore the differences between the composite deckabutment and the cast-in-place concrete abutment design for abutment 06. It will be conductedby modelling the bridge abutment 06 in FEM-Design. The simulated designs will facilitatecost analysis and climate calculation comparisons between the cast-in-place and compositesolutions. Construction documents are provided for researchers through the Swedish TransportAdministration's CHAOS and BATMAN databases. The information provided within thedocument is vital for the cost analysis and climate calculations.The study found that the composite deck abutment had reduced CO2 emissions compared tothe concrete cast-in-place abutment. Secondly, the composite deck abutment was aconsiderably cheaper alternative (cost savings extent to more than 9 million SEK) than theconcrete cast-in-place abutment. The third finding from the study shows that by using thecomposite deck abutment, the construction team would spend 947 days completing the bridge.In contrast, the team would spend 1477 days completing the concrete cast-in-place abutment.These findings indicate that the composite deck abutment is the best alternative for abutment06 of the New Skuru Bridge.
