Foundation
Out of 27 foundations, 25 are open wells. The North abutment and pier No.1 are on raft foundations. The wells have been sunk to 56 m below L.W.L, mainly from scour and seismic considerations. The strata encountered were dense sand mixed with pebbles. During sinking, obstructions in the form of wooden logs and boulders were overcome; this was possible with armoured well curb having shoe-brackets and 12 mm thick steel plates.
With elaborate monitoring at each stages of sinking, it has been possible to position all the wells within permissible limits of tilt (1 in 80) and shift (150 mm) each well costing of Rs. 80 lakh and involving 5,000m of concrete was completed within an average period of 90 days.

Famous quotes containing the word foundation:
“The Bermudas are said to have been discovered by a Spanish ship of that name which was wrecked on them.... Yet at the very first planting of them with some sixty persons, in 1612, the first governor, the same year, “built and laid the foundation of eight or nine forts.” To be ready, one would say, to entertain the first ship’s company that should be next shipwrecked on to them.”
—Henry David Thoreau (1817–1862)
“In a country where misery and want were the foundation of the social structure, famine was periodic, death from starvation common, disease pervasive, thievery normal, and graft and corruption taken for granted, the elimination of these conditions in Communist China is so striking that negative aspects of the new rule fade in relative importance.”
—Barbara Tuchman (1912–1989)
“The institution of the family is decisive in determining not only if a person has the capacity to love another individual but in the larger social sense whether he is capable of loving his fellow men collectively. The whole of society rests on this foundation for stability, understanding and social peace.”
—Daniel Patrick Moynihan (20th century)
