(Rev.1) The dimension tolerance for the piping installation and tie-in point

-
What is the applicable standard and tolerance class for the dimension inspection when the specific tolerance is not stated on the approved drawing? What is the standard tolerance for piping installation and the tie-in point? Regarding steel structures and related materials, if specific tolerances are not addressed in the approved drawing or approved ITP (Inspection and Test Plan), the construction tolerances specified in AWS D1.1 (specifically paragraphs 7.21, 7.22, and 7.23) will be applied. For piping, piping installation, tie-in points, and related materials, if specific tolerances are not addressed in the approved drawing or approved ITP, the construction tolerances specified in ASME B31.3 (specifically Paragraph 335, Erection and Assembly) will be applied. - (Rev.1) Typo & Editorial Errors Corrected
