QMPs for Large D-B & D-B-B ProjectsBrown Bag
Quote
“… If it is signed by George Little, then it is a requirement not a guideline.”
(Bill Raleigh 2012)
QMP is a Project Requirement
Project Quality Management Plan is:• An extension of our internal protocols• Tailored to meet project requirements• Contract requirement

Company vs. Project
COMPANY LEVEL
We typically refer to our internal QC processes as “QC Reviews”.
PROJECT LEVEL
At the project level, we distinguish between Checks and Reviews.• Detail Checking• Constructability Review• Crossdisciplinary Review• Technical Review
Design Quality Management Plan
• Quality Statement - “Quality is the responsibility of each person working on the Project”
• Quality Goal - “… produce deliverables in a well-defined and systematic fashion that meet the contract requirements”
• Quality Objectives - training, submittal reviews, etc.

• Narrative• Appendices

More on the way!
Detail Checking
• Not performed until production toward
a milestone is complete.• Checker is independent of the Originator.• Checker shall not have developed any portion
of the deliverable being checked.• Our work needs to be readable.• Be clear what the intent is.• Spelling counts!
oh, so that is an “H”
Detail Checking
• Rechecker must confirm the edit on a hard copy!
First Page Only: Design Package No. or Description
No. Date
CHECK PRINT Dwg. Only: Checked against calcs. and calc. check confirmed by _________ Date ________

Rechecker Date
The Checker and Rechecker must be independent from the Originator, Backchecker and Updater.
The Checker and Rechecker do not have to be the same person, but it is preferred,
Originator, Checker and Backchecker always required. Updater and Rechecker based on Checker’s red lines.
QC CHECK PRINT COLOR CODING SYSTEM
A color coding system is used for marking on a Check Print to identify various actions to be taken and to identify the various stages of the checking process. We can tailor to a client requirement or project preference, but our internal color coding is: Yellow is used by the Checker to indicate agreement.
Red is used by the Checker to mark-up corrections, changes and additions.
Red is also used by the Backchecker to indicate approval (√) or disapproval (x) of Checker's mark-ups.
Yellow is also used by the Updater to indicate that changes to the original drawing have been made.
Green checkmark (√) is used by the Rechecker to verify that the changes made to the original drawing are correct. A green checkmark (√) is used by the Rechecker to verify that the changes agreed not to be made are not made.
***** Blue or (blue) cloud is used for non-record comments or instructions. *****
Non-record questions, for example, need to be answered in blue. If there is an action by the Backchecker, Updater and Rechecker, then the QC process is followed on the comment. If the comment results in a “significant” correction or addition to the document, then a check print with the change specifically checked is required.
The same color coding is used for all documents and by all members of the design team.
Constructability Reviews
The Contractor can help
see problems:
Crossdisciplinary Reviews
Looking for conflicts
(CDR, DCR, IDR)
Technical Reviews
Project Requirements;
Standard of Care; Industry
Standard.
(TQR, IQR & QCR)
Responses are Important
“There aren’t any utilities on that side of the road;
so put the pole wherever you want”.
Responses are Important
“Just do what it shows on
the drawing!”
Quality Assurance
DQCM will:• Create DQMP• Perform review of QC Documentation• Review submittal prior to submittal• Certify QC performed per DQMP• Perform internal audits, report the results
and resolve nonconformances
May be required to have ASQ, or equal,
Certification
Oversights Happen
Don’t beat yourself up; there is a
reason we perform checks
and reviews.
