In response to these posts, I'd like to make this observation.  The
Inspector is required to adhere to specific criteria regarding the slump of
a particular mix design.  If it is indicated that the slump is "not to
exceed" a particular slump, then that's just what it means.  So, a slump
requirement designated as Not To Exceed 4" means just that.  If on the
other hand, the slump is just specified as 4", the Inspector has some

My point is, Drew, that the issuance of a Certificate of Compliance is, in
itself, self-explanatory and it is not common practice to include the slump
information on a Certificate of Compliance.  Mix Design number, the number
of cylinders cast, the Test Lab they are sent to should be on the
Inspector's report.  Information regarding the ambient and concrete
temperature, slump, mixing time and delivery ticket identification number
among other things are on the data sheet sent with the cylinders.

The responder from the Test Lab is a bit curt and brief, but basically

If you'd like that information, however, you should make your requirements
known.  Herein lies another good reason for the EOR to comply with the UBC
Section 106.3.5 under the Inspection Program.  The Engineer is REQUIRED by
that section to "specify the name of the individual or firm performing the
Special Inspections and what they will be inspecting".  If you specify a
Qualified Inspection Firm and spell out your particular requirements, you
can bet you'll get just what you ask for every single time!
