The footing shall not be sr'na~er than the pier <br /> it supports or 144 square inches, <br /> <br />2 The maximum spacing of supports is not to exceed 10 feet. <br /> <br />3 Where it is impractical to maintain spacing, such as in the axle area, the average of the dislance to each adiacer~[ <br /> support may be used to determine support requirements; for example: if the distances to the adjacent supports were <br /> <br />6'-0" and 8-'0", the average spacing would be 7'-0". <br /> <br /> 6:0" 8'-0" -? -,% \', ............. :.¢¢t <br /> ..~ ~ ...... .,/ ~ <br /> ~ .
