steel must account for three types of toler-ance in their design Mill Tolerance,Fabri-cation Tolerance,and Erection Tolerance.Mills producing hot-rolled structural steel must conform to the ASTM A6 speci- cation as stated in AISCs Manual of Steel Construction,13th Edition.ASTM A6 sets the acceptable variance for member length,Accuracy of steel fabrication - SteelConstructionfoSpecial tolerances.Individual projects may specify special tolerances,either as a modification of the essential or functional tolerances or for aspects not already covered.There is a need for certain additional tolerances on most bridge structures,and these should generally be implemented via the Specification for Highway Works.
