<strong>Construction</strong> of intake Grid Sub Station (GSS) One pipe mill was set up for production of<br />
foundations at strip slope of hill. entire 106 km of pipes for this project<br />
at Phagi due to its strategic location. This<br />
Achieved 93,000 cu.m of concrete and mill helped in the continuos supply of<br />
2,76,000 sq.m shuttering in 21 months. pipes to meet the requirement of the<br />
Dismantling of existing GSS at intake and<br />
commissioning of new 33kV GSS on time.<br />
Out of 76600 t of HR coil 73000 t procured<br />
from China and transported from Mundra Port<br />
to site by road within a period of 3 months.<br />
All buried pipe lines are coated with polyolefin<br />
tape to ensure corrosion resistance throughout<br />
the design life with the help of product procured<br />
from M/s Covalance – USA<br />
All pipe lines have been protected against<br />
corrosion through permanent cathodic<br />
protection system to ensure its designed life<br />
span.<br />
In situ mortar lining was carried out for 106 km<br />
in various dia pipes-2448 mm, 2348 mm, 800<br />
mm & 700 mm to protect corrosion with<br />
minimum C Value of 130<br />
<strong>Construction</strong> of 52 m high surge shaft and four<br />
over head surge tanks<br />
One simple supported MS Bridge of span 25 m<br />
was designed and constructed at IOCL crossing<br />
Raw water transmission main was designed<br />
and constructed over 548 Ring Girders for<br />
carrying the pipe line of 2448 mm dia upto<br />
5.4 km and more than 100 km buried pipe line<br />
to meet requirement of stage two 1020 mld<br />
<strong>Construction</strong> of water treatment plant of<br />
400 mld capacity with 9 pulsators clarifier<br />
and 18 twin bed filters, which is the heart of<br />
the system.<br />
