SQUARING THE FORM WITH STRING LINES (for Metal Building)

Steel Buildings Foundation Layout

Regardless of the type of steel buildings foundation that is used and its specific configuration, the metal building foundation outline should be carefully and accurately laid out before any excavation is made. Whenever possible, a transit or similar means should be used to layout the steel building foundation perimeter; this will insure accurate placement of corner measurements and, in turn, insure a square buildings foundation.

Your building is manufactured to close tolerances and therefore requires a square and level foundation. The following method may be used to achieve the proper steel building foundation:

NOTE: Wind can blow the strings sideways, or the strings might sag while putting up forms. Support the string lines to prevent this if necessary.

For the greatest accuracy, measure the diagonal and adjust the string lines until the two diagonal dimensions are equal. If length A8 = CD, the steel building foundation will be square. (In addition, AD = C8 and AC = 80)
