3. Approval of agenda – The agenda was approved as presented.
4. Approval of Minutes of May 2004 (posted on web site). Moved for approval as
presented by Don McMican, seconded by Ron Barnett. All approved.
5. Update on activity between meetings. Chair Throop gave an overview of the balloting
that had occurred since the last meeting in an effort to address comments received as a
result of the public ballot process. Since the balloting period was shortened to much less
than the normal 30 days, members will not be held accountable for not responding.
However, a lot of really tough issues were effectively resolved.

Construction Requirements Subcommittee
Minutes – October 10, 2004 Meeting
6.1. Chair Throop indicated that the primary, unresolved TAC comments would be dealt
with as a group. Some of the more complex issues that have been on the
Subcommittee’s plate but yet to be resolved would be assigned to Task Groups as
presented under New Business below.
6.1.1. Attachment 1 details the TAC comments addressed by the group at this
meeting and actions taken.
6.2. Don McMican pointed out two errors in the Specification Commentary that needed
to be corrected – “2.6B: ASTM C 476 is strictly a proportion” and in Table C-8 the
values “13611” and “15060”.
7. New Business
7.1. Chair Throop outlined the four task groups and their reports are as follows:
GROUTING ISSUES: Zechmeister, Chrysler, Graber, Crow, McMican, Painter,
Melander
 Dennis Graber will revise the old ballot as discussed and send to the task
group before balloting the subcommittee.
 Language for a subcommittee letter ballot was prepared and will be sent out.
 The task group affirmed the error identified by Don McMican in Table C-8
of the Specification Commentary
UNIT STRENGTH TABLE REVISIONS: Dalrymple, Henderson, Tawresey, Clark,
Throop, Bennett
 Group wrote a ballot item for a revision to Table 2 to reflect minimum
ASTM unit compressive strength requirements.
 Group discussed strategies to obtain data and settled on initial search of
existing articles for data on prism strengths both grouted and ungrouted.
UBC requirements for Table 1 were discussed.
 Throop will contact Clark for input before moving in that direction.
 Dalyrmple agreed to be source for abstract collection. Task group members
to send him abstracts by Dec. 15.
AAC FORMATTING/CLEAN UP: Barnett, Itzler, Jaffe
 Work complete.
 New business items will go through AAC subcommittee, revisions to
wording in specification will funnel through our committee.
 Ballot items will be sent after meeting for sub ballot.
ODDS & ENDS & EVERYTHING IN BETWEEN: Johnson, Laska, Glock, Nelson,
Matt Estes
 Group worked on clean up list with no recommendations for ballot items on
any topic.
8. Adjournment. Don McMican moved for adjournment at 5:07 pm. The meeting was
adjourned.

Motion: M is correct. No

14-0-0
Motion: Paragraph could

needed
as
proportion
requirements are clear –
redundant.
(Rochelle/Don)
14-0-0
Decline to make changes for
same reasons as above.
(Rochelle/Don )
14-0-0
Motion: Not add under
material certificates since
they aren’t necessary to meet
minimum requirements for
life safety. (Don/John C).
13-0-0
Motion: Don’t incorporate for
reasons of redundancy, future
housekeeping, etc. Reference
cannot be confused as there
are only one Table 3, 4,5.
(Ron/Don)
13-0-0
Already addressed by ballot
2005-06 item 145 and 129
(05-08) New draft reads
“flexural tensile strength”
No change. Option needs to
be given to use proportion or
strength methods.
(Rochelle/Dan) 14-0-0
No change. Not unique since
these aren’t unique to the
Specification.
They are
industry terms but are of
particular importance to this
document. (Rochelle/ John C)
14-0-0
Motion: No change. Good
practice per ACI Spec and
ACI style manual suggests
not adding extra or
extraneous adjectives such as
“Additional”. And prism
testing may actually save
expenses on certain project.
(Don/Keith)
14-0-0
( No change. Correct as
