For the construction of the statue, the required concrete strengths varied between 40 MPa to 65 MPa.The statue is located at a remote location, therefore, the material delivery, staging, and erection posed unique challenges for the project.The following points describe the materials used for the construction of the statue: These included a cofferdam, a rock bridge, and an elevated steel bridge. Several options were evaluated for maintaining access to the island during the Monsoon floods.The Bailey bridge has two lanes, one dedicated to vehicle and material movement, and the second one for access to workers.Primarily, a built-up rock bridge which is constructed at the normal flood level, and then a Bailey bridge that is built above the high flood levels. Access to the island is available via two ways.During the monsoon season, the water level typically rises by 5 m, and goes up to 20 m, with very strong currents.The island is accessible from at least one side via land for about eight months of the year as the water level recedes post-monsoon season.This fault has been assumed as a causative fault for the seismic design of the statue. Based on the studies of the area, the nearest fault exists at a distance of 22 km from the site of the statue.The data on earthquake occurrence shows that the Maximum Credible Earthquake (MCE) in this area can have a magnitude of 6.5.The project is located in the seismic zone III of the seismic zoning map of India.Dykes are aligned in the NE-SW direction. The sedimentary rocks at the site consist of quartzite sandstone, argillaceous sandstone, shale, pebbly sandstone, and limestone.The project site is occupied by the Deccan basalt flows underlain by sedimentary rocks.The following points describe the geology of the site: ![]()
