ADDITIONAL SPECIAL PROVISIONS (ASP-6)
SECTION 106QMP dispute resolution process and CMM Chapter 8,
Sampling and Testing Methodologies mobilized into the contract
Required sampling and testing methodologies and documentation are specified in CMM chapter 8
If disputed, approval of materials and components, as well as acceptance of the work incorporating those materials or components, is subject to review under the QMP dispute resolution process

SECTION 501 Sampling And Testing Specifications References Have
Been Revised
SECTION 701Contractor Testing – Testing References Have Been
Revised
SECTION 715Department Verification Testing – Testing Increased To

WisDOT Quality ManagementProgram (QMP)
What’s New ??
Mechanically Stabilized Earth (MSE) Wall
Pilot Spec to be used in SE District projects, first on panel walls
Requires QMP testing of backfill materials and compaction (T-99)
Requires certified testers of backfill placement and compaction -
Gradingtec I , Aggtec I and Nuclear Density I
The supplied wall system must be from the department’s approved list of concrete panel mechanically stabilized earth wall systems.
WisDOT Quality ManagementProgram (QMP)
Dispute resolution process for non-conforming materials - Section 106.3.4.3.5 - defined as:
Engineer and contractor to make every effort to avoid conflict
Contractor Inspections, testing, corrective actions and process control charts are to be used to determine solution
Third party testing will be used if resolution cannot be made by evaluating existing data
WisDOT Quality Management Program (QMP)
Non-Performance Process, CMM Section 8-30.13
Engineer to notify contractor early to address problem
If corrective action taken-no further action maybe necessary
If non-performance continues – one of three actions are considered: Suspend or delay contract operations Withhold payment on material bid item affected Administer pay reductions using the following
guidelines:
WisDOT Quality Management Program (QMP)
WisDOT Quality Management Program (QMP)
Additional Non-Performance Administration Action Effective - August 4, 2012Before penalties are assessed the
following occurs:Engineer will review problem with their regional
materials engineer If reduction is significant or controversial, it will
be reviewed by:Bureau of Project Development (Don Greuel)
and Bureau of Technical Services (Steve Krebs)
WisDOT Quality Management Program (QMP)
Additional Non-Performance Administration Action Effective - August 4, 2012 (Cont.)
Criteria to be provided for review isItems where QMP was not performedAmount of proposed deductTotal value of items with non-performance of
QMPNumber of missed testsBrief narrative of measures taken to ensure
compliance and justification of the proposed reduction
Decision on Concur/Non-concur within three working days
Source Documentation CMM Section 8-30 - QMP General:
Source Documentation Is:Test Data Entered Directly Into Electronic
Document or Original Handwritten Test Data
Project Record SubmissionRecords Shall Include The Original Source
(Electronic Or Handwritten) DocumentsEven If The Original Handwritten Document Was
Transferred Into An Electronic Document, The Hand Written Document Shall Be Submitted
When Supplying The Original Source Document, A Scanned Copy Is Acceptable
How are we assured we are getting what is required?
• Quality of Materials and Proper Installation is key
• Three part Quality Management Program (QMP) -• QC Testing by Contractors• QV Testing by Department Staff• Independent Assurance/Oversight by Department Staff
• How do we make sure this system work?
• All Sampling and Testing is conducted by Certified Technicians
How are we assured we are getting what is required?
AND IMPORTANTLY
Project staff checks for appropriate certifications to assure that only certified technicians are used for all sampling and testing
CERTIFICATION• Certification/Training is provided by HTCP- UW Platteville
• Multistate-locations
• Certification good for 3 Years
• Training is provided January thru July
• Skilled Technicians trained to national and state standards
• Certification is achieved by demonstrating proficiency thru Testing Sampling Techniques, Lab Procedures and Specification knowledge
• PDH’S are earned at classes

HMA Truck Box Sampling (NEW)Standard Spec 2013, ASP 6 requires increased frequency of the QV sampling and testing from 1/30,000 tons per mix design to 1/5,000 per mix design.
QV observer needs to have a minimum of Hot-Mix Asphalt-Truck Box sampling, HMA-TBS to augment there certification in aggregate sampling, AGGTEC-I, AGGTEC-II and/or ATTS.
In the interim, any of these technicians can update their certifications to include HMA-TBS, requesting the DVD with instructions, the self-paced study materials, and the exam. This training will be available on-line in 2013.
For those individual seeking HMA-TBS certification enroll in the 2013 Aggregate Sampling certification course.
