Reference Question Responses Page Section Paragra ph

1 09/10/25 28 31 70 1.3.2(a) This section states that shop drawings must bear a PE seal and prepared by, or under the immediate supervision of, the FPQC. While this is per the unedited guide specification, it is also somewhat contradictory to paragraph 1.5.5, which only calls for FPQC review of the submittal. Please advise if the 2nd and 3rd sentences of 1.3.2(a) may be deleted. Note that we have routinely deleted these sentences on projects where we are the designer of record, without objection from NAVFAC ML FPEs.

Delete the 2nd and 3rd sentences of 28 31 70 ¶1.3.2.a ("Construction (shop) drawings and calculations must be prepared by, or prepared under the immediate supervision of, the FPQC. The FPQC must affix their professional engineering stamp with signature to the shop drawings, calculations, and material data sheets, indicating approval prior to submitting the shop drawings to the DFPE.").
