· AWWA D100 REQUIRES THE LOWEST ONE-DAY MEAN AMBIENT TEMPERATURE FOR THE LOCATION OF THE TANK PLUS 15 DEGREES FAHRENHEIT. THE SITE FALLS ON

THE NORMAL ISOTHERMAL LINE OF 30 DEGREES FAHRENHEIT. THEREFORE, THE DESIGN METAL TEMPERATURE SHOULD BE 45 DEGREES FAHRENHEIT.

· A BUTT WELDED ANNULAR RING WILL BE REQUIRED AT THE OUTSIDE PERIMETER OF THE FLOOR. STANDARD LAP WELDS WILL BE ACCEPTED ON THE REMAINDER OF

THE FLOOR.

SHALL BE PERFORMED PER THE TECHNICAL SPECIFICATIONS, FOLLOWED BY INTERMEDIATE AND FINISH COATING IN THE FIELD PER TECHNICAL SPECIFICATIONS.

INTERMEDIATE AND FINISH COATS DO NOT NEED TO BE APPLIED TO THE TOP FLANGES OF RAFTERS SEAL WELDED TO THE ROOF PLATE.

· ALL JOINTS SHALL BE SEAL WELDED, INCLUDING ROOF PLATE & RAFTER CONNECTIONS. RAFTER TO ROOF PLATE SEAL WELDS MAY BE COMPLETED IN THE SHOP.

ROOF PLATES MAY BE WELDED TO OTHER ROOF PLATES IN THE SHOP OR IN THE FIELD: THOSE WELDS MUST BE LAP WELDS WITH COATING PREPARATION AND

APPLICATION PER DIVISION 9 OF THE TECHNICAL SPECIFICATIONS.

· TO MEET CURRENT DEFLECTION STANDARDS DUE TO SERVICE LOADS, THE TANK MANUFACTURER MAY UTILIZE ANY OF THE FOLLOWING MEANS, PROVIDED THE

MANUFACTURER PROVIDES PE STAMPED SHOP DRAWINGS AND CALCULATIONS SUPPORTING ITS DESIGN, INCLUDING: RAFTER CAMBERING, OR AN INCREASED
