Ranjit Conducts Pile Load Tests for Ahmedabad Metro’s Phase 2

Over the past couple weeks, Ranjit Buildcon and Cimec Technologies have been conducting initial vertical pile load tests at two sites between GNLU and Gandhinagar’s Sector-1 for constructing the 28.254 km Ahmedabad Metro Phase 2 project.

These tests are performed to find the ultimate load the pile foundation can support or bear when loaded. Results from it are used to validate the safe pile capacity considered for supporting the viaduct’s superstructure.

During the test, engineers typically transfer load to the pile using capacity jacks in small increments and maintain it for about two hours. During this time, the settlement of the pile is measured every 15 minutes using dial gauges on the surface of the pile.

Ranjit Buildcon was awarded Phase 2’s 6.478 km Package C2 in late-2020 with a contract value of Rs. 417.90 crore. Their scope of work includes 5 stations at Raysan, Randesan, Dholakuva Circle, Infocity, and Sector-1. A small 0.679 km ramp will be built leading to a new depot at Indroda Circle.
