acceptable material
 Verify all material issues are resolved
 Verify Exceptions are complete and
accurate
 Verify the Exceptions match w/ Pay
penalties
 Verify all supporting certifications for
materials accepted by certification are
received and meet specifications
Engineering
Analysis Report
What is an EAR?
 A report prepared by an approved
licensed engineer providing analysis of
failing material left in place
 Evaluation of affected material, e.g.,
Analysis of additional samples, Life
Cycle Cost Analysis, etc
 Reporting structural adequacy with
reference to the design criteria
 “Disposition of Defective Material” form
Non-standard
material
left is
in place
EAR Processing
Contractor

use Of EAR
Use EAR ?
No
Disposition
implemented
DCE approves
disposition
SCE makes final
decision
DCE forwards
package to SCE
Yes
Concur ?
PA sends EAR &
disposition to DCE
No
DCE prepares
recommendation
DME reviews EAR
and proposes
disposition to PA
Yes
PA & DME
set up parameters
PA. authorizes
use Of EAR
Contractor
submits EAR w/
recommendation
to PA
PA forwards
a copy of EAR

Project
Administrator’s
Materials Statement
Financial Project #:
Federal Project #:
Contract #:
County:
All materials incorporated into the referenced project(s) were accepted
in accordance with the STRG or pertinent contract documents and
met all applicable requirements.
•Earthwork density test locations and results are in substantial
compliance with the pertinent specification requirements of this
project. A spot-check of the project density records indicate
substantial compliance with the governing specifications, sampling
and testing guides, and procedures.
•All Contractor Quality Control (QC) material test results have been
verified in accordance with contract requirements. The final
disposition of all material represented by QC results has been
accurately documented.
•All required certifications and/or certified test reports have been
received in accordance with contract requirements.
• Earthwork density test
locations and results are in
substantial compliance with
the pertinent specification
requirements of this project. A
spot-check of the project
density records indicate
substantial compliance with
the governing specifications,
sampling and testing guides,
and procedures.
• All Contractor Quality Control
(QC) material test results have
been verified in accordance
with contract requirements.
The final disposition of all
material represented by QC
results has been accurately
documented.
• All required certifications and/
or certified test reports have
been received in accordance
with contract requirements.
Exceptions
What are Exceptions?
(to the Certification)
Material Not Meeting Standards
For CQC Testing:
 Asphalt does not meet standards if C.P.F. for
a Lot is less than 90%
– However, we are noting failing tests, at the
request of the Bituminous technical unit
 Concrete does not meet standards if
“payment tests” do not pass
 Earthwork does not meet standards if ‘QC’
tests do not pass and are not verified
What are Exceptions?
(continued)
Material Not Meeting Standards (cont.)
For Non-CQC Testing:
 Material does not meet standards if ‘V’ test
does not pass
Testing Frequency
 Material not tested, or tested at a frequency,
not in conformance with the Specifications
and left in-place
What are Exceptions?
(continued)
Qualifications
 Sampling and testing performed by unqualified
technicians (when specified in the Contract
documents)
 Testing performed at unqualified laboratories
or at qualified laboratories during a time that
they were removed from the list of Qualified
Laboratories
 Materials produced when the production
facility was not on the accepted list, and left inplace
You have an Exception, how
do you report it?
 Description
 Location
 Quantity
 Resolution (and at what pay)
 Concurrence…obtained?
Example of Format
Concrete, Class IV
The following Quality Control and Verification
samples did not compare within the required
tolerance. Resolution was not performed
therefore these areas are not verified.
Sample

Result (psi) Quantity (cy)

-------
Project personnel recommended leaving the
material in-place at full pay based on the QC
results. The District Materials and District
Construction Engineers concurred.
Our Review
(the process & tools)
• Method of Acceptance –
What we look at: for all materials that have a
paid qty, make sure have proper method of
acceptance (examples: sampling and testing
or certification)
USE: Final pay estimate for Reg. Pay Item
Projects
*For Design Build and Lump Sum we use the
final Job Guide Schedule
• Open Samples
Use: Sample Status Progress Report
and Samples Not Tested Report
The samples on these reports need
follow up. They may need to be
processed through LIMS (from receipt
to approval)
• Failing Material
USE: Samples with Disposition other
than Full Pay per Spec (FS) Report
For material not meeting standards.
Do we have a DDM documenting
resolution and concurrences?
• Unqualified Personnel and Labs
When contracts specify to have qualified
technicians and labs
Requirements will be under spec book
Section 105 for both personnel and labs.
Need justification and how accepting
material tested by unqualified personnel
or labs
• Material Certifications
USE: Required Certification Tracking Report
to determine certifications that need to be
sent to Gainesville
Make sure only those certifications that come
to Gainesville are logged in LIMS
Others (sampled by PP tested by PP) are
scanned into Hummingbird with the project
files
• Random Sampling Program
For more information, see section in the
Materials Manual 5.6.15
• Individual Material Review
For example: Earthwork, Concrete,
Asphalt, Reinforcing Steel and all other
materials
Make sure sampling and testing
frequency is met per specifications
Since, at times the data entry in LIMS is
less than adequate (garbage in, garbage
out), we need additional information
Data for Base LOTS
Frequency: One QC test per 8 LOTS
One VT test per 16 LOTS (every 2 QC)
Data for Structural Concrete LOTS
Frequency: One QC test per 50 cy or day’s production
One VT test per 4 LOTS (same mix design)
Steel Samples
• Please submit the steel sample as soon as it is
received at the project, do not wait until final
acceptance
• The SMO Lab will store an unidentified sample for
2 weeks before it is discarded
• If your sample is discarded deliver one of the
“hold” samples with the appropriate paperwork
– Copy of LIMS C22, tag and mill analysis
– Do not login a separate LIMS entry for the “hold”
sample . The LIMS ID for the original sample will
be used for the “hold” sample
– LIMS life cycle must be completed
