USE, SITE PLANNING, EROSION CONTROL, ELECTRICAL, MECHANICAL, FLASHING AND WATER-PROOFING ARE
BEYOND THE SCOPE OF THESE DRAWINGS AND ARE PROVIDED BY OTHERS. EXISTING STRUCTURAL ELEMENTS ARE
DESIGNED BY OTHERS. ANALYSIS FOR MOVEMENT DUE TO VORTEX SHEDDING OF WIND FORCES IS NOT INCLUDED
IN THE SCOPE OF WORK. IF MOVEMENT CAUSED BY VORTEX SHEDDING IS A CONCERN, WIND TUNNEL TESTING OR
OTHER ANALYTICAL MODELS SHALL BE UTILIZED TO EVALUATE THE STRUCTURE.
IN ACCORDANCE WITH SECTION 1704.2 EXECPTION 1, NO SPECIAL INSPECTIONS ARE REQUIRED FOR WELDS AS THE
LOADING IS A MINOR FRACTION OF THE CAPACITY OF THESE ELEMENTS.
