1.7 TECHNICAL PROCUREMENT REVIEW
NAVFACINST 6250.4B requires that Requisitions and Invitations for Bid
for treated wood products which deviate from the instruction be reviewed
and approved by the cognizant NAVFAC EFD Applied Biologist prior to
submission. This requirement will insure that the most appropriate
product is ordered, that current treatment specifications are cited, and that
Applied Biologists are alerted to pending procurements which may require
actions to insure product quality.
Review requirements may be waived or reduced by the cognizant EFD
when an activity has been shown to be consistently receiving products of
acceptable quality. Review guidance may then be provided on an as
necessary basis to maintain acceptable product quality levels.
