Gst railway crossing at the junction of ranip and new ranip is affected by heavy dense traffic. the existing railway crossing has very less capacity to handle the traffic in normal hours, while the scenario is almost worst during peak hours. new ranip is one of the most growing residential are in ahmedabad and require proper connectivity without and hassle to the road users. after several thinking and research in design and site ahmedabad municipal corporation decides to construct rob (rail over bridge), which will reduce the conflict points and provides ease to users. there are basically two types of railway bridges,"railway over bridge" and "railway under bridge". this area is very crowded and highly affected by monsoon water, as well as railway authority denied to permit for under bridge due to technical reasons too, hence rob is the only option for proper connectivity. railway bridge will be on pile foundation because it transfers the load of super structure to the soil in which they do not have adequate bearing capacity. we are interested to study design of pile foundation and will review all the technical aspects of the design. we want to satisfy our selves "why these type of piles are used? " and also study the design manually with the is code 2911. we will also study the settlement of the bridge by collecting the data from the project site, the vertical ultimate bearing capacity of pile group and the dynamic action of the train loads by this study. we are intent to review the whole design and want to conclude whether the design is safe or not?, we will also want to go for alternative design options too...
