The Year in Infrastructure 2007 - (Page 60) ciVil rOad infrastructure Multi-Sector Project for Rehabilitation of Infrastructure in Jammu and Kashmir, India span consultants pvt ltd This project involved the design of a 300-kilometer road network in the Srinagar region of Jammu and Kashmir in northern India. At 1,600 meters above sea level, the terrain of this region, which shares a border with Pakistan and China, is mainly hilly, comprised of sharp curves, hair-pin bends, and steep gradients. Due to severe site constraints and the requirement to have an optimized design, there are frequent changes in the alignment design, dramatically increasing the quantum of work. Bentley’s MX solutions provided precise digital terrain and 3D modeling, minimizing the number of site visits required to this geographically challenging area. In addition, 3D visualization improved sight distance analysis and setback distance, which can be very helpful when designing roads in such complex and hilly terrains. Use of the software shaved eight months from the project schedule. S.S.106 Jonica Megalotto 8 ste srl S.S. 106 Jonica, the main road connecting the cities of Reggio Calabria and Taranto in Italy, is 490 kilometers long. Megalotto 8 is 53 kilometers long and connects the cities of Mandatoriccio and Sibari. Modernizing these roads will improve the overall quality of the roadway system in this area, relieve traffic congestion, and shorten travel times. STE used Bentley MX solutions to verify all road design rules, including production of a speed diagram, control of the plan and vertical congruence, and a full 3D visibility analysis based on the 3D geometry of the design and expected operational speeds. STE also used the software to enable collaborative workflows and guarantee a fully coordinated and integrated design. Spatial coordination and complete understanding of the interface between the designed roads and existing buildings and services was analyzed in detail. 60 ThE YEAR IN INFRASTRUCTURE 2007
