CONTACT DESIGNER FOR CLARIFICATION OF DIMENSIONING AND ANNOTATE ON THE RECORD DRAWINGS ANY MISSING DIMENSIONS. 4. DETAILS ON THE DRAWINGS TAKE PRECEDENCE OVER GENERAL NOTES AND TYPICAL DETAILS. 5. DETAILS NOTED AS TYPICAL APPLY TO ALL SIMILAR CONDITIONS. WHERE NO SPECIFIC DETAILS ARE SHOWN, CONSTRUCTION SHALL CONFORM TO SIMILAR WORK ELSEWHERE. 6. THE STRUCTURE IS DESIGNED TO FUNCTION AS A COMPLETE UNIT. THE CONTRACTOR IS RESPONSIBLE FOR FURNISHING ALL TEMPORARY BRACING AND SUPPORT THAT MAY BE REQUIRED AS THE RESULT OF THE CONTRACTOR'S METHODS AND SEQUENCING OF CONSTRUCTION. 7.
