Newton AssocLates, Inc. (DNA) is:, pleased to present the results of our <br />geotechnical investigation for the Aurora cell site. The investigation was performed in <br />accordance with our proposal dated June 7; 1995. <br /> <br />PURPOSE AND SCOPE OF iNVESTIGATION <br /> <br />This report has been prepared for GTE Mobilnet and their consultants for nsein project <br />design and construction, and presents conclusions regarding general, subsurface <br />conditions at the Aurora cell site and foundation design recommendations for the <br />monopole and the switch building. <br /> <br />DESCRIPTION OF THE PROJECT <br /> <br />A cellular phone transmission cell will be constructed on a portion of undevelOped land <br />south of Ehlen Road and east of Dolores W~ay in Aurora, Oregon, The cell will consist <br />of a 150-foot high, steel monopole and a switch building. The approximate location of <br />the. site is shown on Figure 1. The layout of the site is shown on the Site Plan in Figure <br />2. <br /> <br />The monopole will have a base diameter of approximately 59 inches.,:..Maxlmum design <br />loads on the monopole are estimated to be approximately 32 kips downward, 25 kips <br />shear, and approJumately 2,415 foot-kips m bending. <br /> <br />The switch building w/Il be approximately 121 feet by 20 feet, and will lie Supported on <br />spread footings. <br /> <br /> 1201 $.W. 12th Ave., Suite 400 · .Per,and.
