Wisconsin Enrolled Commercial Build

[EIT2]

Wisconsin Enrolled Commercial Building Code and BOCA both, similarly state "...foundation walls, piers and other permanent supports of buildings and structures ...shall extend below the frost line of the locality.

As a general rule in my area of Wisconsin, we assume frost levels to be 40-48" below grade. This, however, has only been, to my knowledge, a well-accepted common assumption.

I need to determine the frost depth in Philips, Wisconsin, which is further north from my area.

Does anyone have or know of a handy map, chart or useful reference showing frost depths per locality?

Thank you!

1) Ask your geotechnical engineering consultant for the frost depth

2) Call the Phillips local government for the building inspector phone number and ask tha building inspector what the frost protection depth is. It may be different for residential and commercial.

cphi has the answer. Design frost depth (usually 100 year) depends upon many geotechnical factors or it can be determined from local experience. The simplest approach is to ask the local building inspector. Otherwise you have to look into the number of degree freezing days and soil type to determine an estimate of the depth of frost.
