Building Codes
Building codes sometimes take frost depth into account because of frost heaving which can damage buildings by moving their foundations. Foundations are normally built below the frost depth for this reason. Water pipes are normally buried below the frost line, or insulated to prevent them from freezing.
There are many ways to predict frost depth including factors which relate air temperature to soil temperature.

Famous quotes containing the words building and/or codes:
“The real dividing line between early childhood and middle childhood is not between the fifth year and the sixth year—it is more nearly when children are about seven or eight, moving on toward nine. Building the barrier at six has no psychological basis. It has come about only from the historic-economic-political fact that the age of six is when we provide schools for all.”
—James L. Hymes, Jr. (20th century)
“Thou hast a voice, great Mountain, to repeal
Large codes of fraud and woe; not understood
By all, but which the wise, and great, and good
Interpret, or make felt, or deeply feel.”
—Percy Bysshe Shelley (1792–1822)
