Project in Brief : Multi-bay, multi-span industrial shed admeasuring 2550 sqm., for manufacture, assembly and testing of Primary Coolant Pumps for Nuclear Power Projects, consisted of one bay of 18m span-14m in height with two EOT cranes of 60T & 25T capacity and the other two bays of 14m span-12m in height with EOT cranes of 10T capacity in each bay. Adjoining the main shed were compressor and DM water plant room and electrical control room. Involved compressor and other machinery foundations, pits, trenches etc.

RSR Test Pit : The pump along with its motor, weighing 75 MT is mounted on a steel test rig and is tested in this pit. While testing the pit is filled with water. The plan dimensions of the pit were 12m X 5m. The major part of the pit was 5.5m deep and the remaining part was 2.5m deep. The ground water table being high the base raft was designed for uplift pressure. The thickness of the base raft was 675 mm and that of walls was 675mm at base and 150mm at top.

AEC was also entrusted with vetting of design of steel test rig. The structural steel rig had a base diameter of 3.425m and a height of 5.5m.
