13. ABSTRACT (Maximum 200 words)
A 2000-ft2 addition to an aircraft control tower was constructed at Galena, Alaska, during the summer of 1990.
Because of limited resources, a shallow insulated foundation (SIF) was specified instead of a traditional founda-
tion (one in which the bottom of the footing is placed lower than the anticipated depth of frost penetration). An
SIF design allows the footing to be placed at a much shallower depth by incorporating the use of strategically
placed insulation around the foundation. The insulation utilizes heat from the building and surrounding soil,
redirects it to the area around the foundation, and thus reduces the frost penetration.
