The load3 are preliminary, approximate, estimated, and do not include foundation concrete weight. These loads are unfactored for service condition. Final loads will vary based on actual equipment and structural configurations. 2. Coordinate Z-axis is vertical, X-axis is transverse and Y-axis Is longitudinal. Forces Fx and Fy. and Moments Mx and My shall be assumed to act simultaneously. Moment Mz about vertical axis will cause torsion. Force Fz is primarily weight of the equipment or structure. 3. Transformer weight assumed to be supported by 12 feet wide and 15 feet long block foundation. 4. Control building assumed supported on 16 feet wide by 40 feet tong pad. 5. GIS building wall and sound wall load unit Is kips per linear foot. Pane D 2 ] PLATE 11
