Advantages • Reduced Noise : Free Sound barriers, • Reduced Visual Impact : by 50%, • Reduced Disturbance during construction, • Improved Aesthectics, • Improved Quality • Reduced Cost : Up to 30% cost reduction, • Reduced Construction Time : Up to 60% reduction, • Reduced Maintenance, • Reduced Construction equipment Costs No communication or reproduction without prior authorisation of SYSTRA U Shape – Typical Spans Typical Spans in a range of 25 to 35m: • Santiago de Chile L4 and L5: 35m spans • Delhi Metro : 25m and 32m spans • Dubai Metro : 32m spans • Neihu Line (Taiwan) : 25m spans • Mumbai metro : 30m spans • Delhi Airport Link : 25m spans • Uijongbu LRT : 30m spans • Shanghai line : 30m spans • Lahore metro : 30m spans No communication or reproduction without prior authorisation of SYSTRA Construction Methodology : Suitable for all kind of standard and industrial construction Methods Full precast spans, segmental, cast in place, … Standard Span Lenghts : Typical and economical section in a range of 25-40m Up to 35/40m simple spans Medium and long Spans : Smooth transition with typical spans Up to about 45m : continuous structures with same segments Or extended Pier Caps 45-55m : Composite through bridges 45-90m : U box in prestressed concrete More : Extradossed bridge, arch bridges, cable stayed bridges … With typical « U » shape segments Proven Construction Cost Savings : Up to 25-30% compared to conventional designs Very important construction schedule optimization Reduction of the maintenance Environmental : Reduction of permanent visual obstruction by half Sound barriers for free Structure borne vibrations similar to standard solutions and fully acceptable Other advantages : Simple construction : can be done by most of contractors Fully integrated structure with the system and operation Lowering of the profile and increase of passenger comfort No communication or reproduction without prior authorisation of SYSTRA •The « U »
