Assuming the weight of dirt to be 120 <br />pounds per cubic foot, the total dirt load per square foot at the <br />pipe would be 2,400 pounds. The 60 kip load from the building <br />footing would be disipated at the 20 foot depLY� oF abandoned <br />pipe to a total of 96 pounds per square foot. This adds up to <br />2,400 pounds per square foot from dirt plus 96 pounds per square <br />foot from imposrd bui7ding, adding an insignificant luad, therefore <br />in our opinion filling abandoned pipe should not be necessary. <br />Thank you for your consideration in this matter. <br />S+ncerely, <br />LANCE MUELLER & AS50CIATES/ARCHITECTS <br />IC AR�H ��i�" _ \ <br />RH:nk <br />cc: Mr. Nawie Matteson Hart Crowser & Assoc., Inc. <br />The Rainier Fund Baugh Construction <br />Engineers N.W. <br />1�0I�k��ld� ��ult� f��uCtl�� we�hlnplon BB1QQ (QOe) 3Q6•@6E3 <br />Ima� mu�ll�r �1�� o�l � e •.�o1wCu� rob�rt ol�oh�w�ky, �Il��n fu�n�y <br />� uiuhlnplan oorpar�Clon fu�nl�hinp arohlC�otu��l wrvlo�� 6y �ntl und�r Oh� �up�rvl�lon of r�pl�t�r�d �rohlt�ac• <br />
