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

•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.

PA Statement
• 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.
Florida Department of Transportation
PA Statement – Details
• 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.
Florida Department of Transportation
PA Statement – Details
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%• Additionally, 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 either QC or VT tests do not pass (and are unresolved)
Florida Department of Transportation
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, regardless of payment
Florida Department of Transportation
Exceptions (cont.)
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 in-place
Florida Department of Transportation
Exceptions (cont.)
How do you report an Exception?

Florida Department of Transportation
Example of Format
Florida Department of Transportation
• 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 Station Result (psi) Quantity (cy)• CC4006V 806+77 to 807+97 7983 22.25• CC4006Q ------------------------ 9330 -------
• Project personnel recommended leaving the material in-place at full pay based on the QC results. The District Materials and District Construction Engineers concurred.
Method of Acceptance
Florida Department of Transportation
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
Florida Department of Transportation
These are samples that have not completed processing (e.g. Approval Status)
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
Florida Department of Transportation
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
Florida Department of Transportation
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
Florida Department of Transportation
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 5.10
Individual Material Review
Florida Department of Transportation
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
Florida Department of Transportation
Frequency: One QC test per 8 LOTSOne VT test per 16 LOTS (every 2 QC)
Data for Structural Concrete LOTS
Florida Department of Transportation
Frequency: One QC test per 50 cy or day’s productionOne VT test per 4 LOTS (same mix design)
Steel Samples
Florida Department of Transportation
• 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
