1 Mn/DOT AUDIT 2010 COUNTY HIGHWAY ACCOUNTANTS CONFERENCE SINGLE AUDIT DISCUSSION

2 SINGLE AUDIT OUTLINE 3 How Your Project Gets Selected For Audit 3 ARRA Requirements 3 Material Testing 3 Single Audit Report Process

3 HOW YOUR PROJECT GETS SELECTED FOR AUDIT Single Audit Act of 1984: Highway Planning and Construction Program Agreement With Office of Legislative Audit Letter of Agreement and Stewardship Plan Between Mn/DOT and the Federal Highway Administration Population of Highway Construction Payments for the State Fiscal Year Ended June Highway Construction Projects Selected for Audit (some trunk highway and some city/county) Factors Influencing Selection: Project Size, American Recovery and Reinvestment Act (ARRA), Project Type, Location FHWA guidance to us for this year: audit 2/3 city/county projects and 1/3 trunk highway projects; also, 50% ARRA projects

4 AMERICAN RECOVERY AND REINVESTMENT ACT (ARRA) REQUIREMENTS See pages and specific page references belowhttp://www.whitehouse.gov/omb/assets/a133_compliance/arra_addendum_1.pdf Need to have certification that ARRA Buy American provisions are met for Iron, Steel, and Manufactured Goods; also need Buy American provision in ARRA project proposals, page 33 of 301 Proposal language and practices addressing use of debarred contractors needs to be the same between Federal and non-federal (state aid) projects, page 33 of 301 Schedule of Federal Expenditures in annual financial reports needs to separately document ARRA expenditures, page 52 of 301 Data Collection Form (SF-SAC) in Single Audit Clearing House (http://harvester.census.gov/sac) needs to separately document ARRA expenditures, page 52 of 301http://harvester.census.gov/sac Cities and Counties must be registered in the Central Contractor Registration (CCR) database (https://www.bpn.gov/ccr/default.aspx ), page 45 of 301https://www.bpn.gov/ccr/default.aspx Contractors should be submitting reports indicating hiring for ARRA projects – reports should be checked for accuracy – see change in federal requirement addressing use of full-time equivalent for calculating hiring for ARRA projects

5 MATERIAL TESTING Assess Measures Taken to Accomplish Compliance With Material Testing Requirements Grading and Base Testing Requirements Concrete Production/Testing Compliance Bituminous Production/Testing Compliance

6 Recent Audit Results: Material Testing (Grading & Base) Audit Finding for 3 Consecutive Years Opportunities for Improvement Opportunities for Improvement Payment reductions need to be taken at the time of payment for work rather than at the end of the project (failing gradations; bitumen content) Payment reductions need to be taken at the time of payment for work rather than at the end of the project (failing gradations; bitumen content) Preliminary and Final Grading and Base Reports Need to be Completed correctly and Sent in to the Grading and Base Unit (Grading and Base Manual, ) Preliminary and Final Grading and Base Reports Need to be Completed correctly and Sent in to the Grading and Base Unit (Grading and Base Manual, ) Contractor Certificate of Compliance and QC Gradations Must be Submitted to and Accepted by the Engineer Prior to placement and payment (2005 Specification F1, Special Provisions) Contractor Certificate of Compliance and QC Gradations Must be Submitted to and Accepted by the Engineer Prior to placement and payment (2005 Specification F1, Special Provisions) QA gradations need to be done with Random Sampling Method per Schedule of Materials Control and Grading and Base Manual Chapter 7 (also Random Sampling Acceptance Report – Grading and Base Manual) QA gradations need to be done with Random Sampling Method per Schedule of Materials Control and Grading and Base Manual Chapter 7 (also Random Sampling Acceptance Report – Grading and Base Manual) Perform DCP tests (Schedule of Materials Control) Perform DCP tests (Schedule of Materials Control) Perform Relative Density and Relative Moisture Tests (Schedule of Materials Control) Perform Relative Density and Relative Moisture Tests (Schedule of Materials Control) Moisture Content Tests Must be Done to Verify 5% Moisture to Achieve Compaction (Schedule of Materials Control, 2005 Specification C2, C3, Special Provisions) Moisture Content Tests Must be Done to Verify 5% Moisture to Achieve Compaction (Schedule of Materials Control, 2005 Specification C2, C3, Special Provisions) QC and QA Percent Crushing (Schedule of Materials Control, Specification C) QC and QA Percent Crushing (Schedule of Materials Control, Specification C) Aggregate Quality (Schedule of Materials Control, Specification D, 2E) Aggregate Quality (Schedule of Materials Control, Specification D, 2E) Need to Verify Maximum of 3% Bitumen Content for Aggregate Base Class 7(B) (Specification A2a(a)) Need to Verify Maximum of 3% Bitumen Content for Aggregate Base Class 7(B) (Specification A2a(a)) Materials Certification Exceptions Summary needs to list missed tests and failing tests and resolution during the project as well as when the project is finaled(Contract Admin Manual page MATLCERT-4) Materials Certification Exceptions Summary needs to list missed tests and failing tests and resolution during the project as well as when the project is finaled(Contract Admin Manual page MATLCERT-4)

7 Recent Audit Results: Material Testing (Concrete) Success in Meeting Requirements Success in Meeting Requirements QC and QA Coarse and Fine Aggregate Gradation Tests Usually Done as Required QC and QA Coarse and Fine Aggregate Gradation Tests Usually Done as Required Cylinder Tests Done as Required Cylinder Tests Done as Required Opportunities for Improvement Opportunities for Improvement Need to Complete and Submit Weekly Certified Ready Mix Plant Reports and Test Beam Data to the Concrete Unit (Concrete Manual, ; (1)) Need to Complete and Submit Weekly Certified Ready Mix Plant Reports and Test Beam Data to the Concrete Unit (Concrete Manual, ; (1)) Cores for Thickness need to be done (Schedule of Materials Control) Cores for Thickness need to be done (Schedule of Materials Control) Take payment reductions for air content falling outside specification (Specification A4b) Take payment reductions for air content falling outside specification (Specification A4b) Conduct Coarse Aggregate Testing on No. 200 sieve (Specification D1(i), Schedule of Materials Control) Conduct Coarse Aggregate Testing on No. 200 sieve (Specification D1(i), Schedule of Materials Control) Cementitious Materials and Admixtures for Concrete testing needs to be done Cementitious Materials and Admixtures for Concrete testing needs to be done Contractor needs to perform and document QC verification companion sample gradations (Schedule of Materials Control) Contractor needs to perform and document QC verification companion sample gradations (Schedule of Materials Control) Contractor needs to perform and document QC moisture testing for aggregates Contractor needs to perform and document QC moisture testing for aggregates Air and Slump Tests should be taken as required and Documented on the Weekly Concrete Report (Schedule of Materials Control, Concrete Manual ) Air and Slump Tests should be taken as required and Documented on the Weekly Concrete Report (Schedule of Materials Control, Concrete Manual ) Certificate of Compliance Needed for Dowel Bars (Schedule of Materials Control) Certificate of Compliance Needed for Dowel Bars (Schedule of Materials Control) QA/verification testing needs to be performed by agency/agency controlled personnel; QC testing needs to be performed by contractor/contractor controlled personnel (23 CFR and ) QA/verification testing needs to be performed by agency/agency controlled personnel; QC testing needs to be performed by contractor/contractor controlled personnel (23 CFR and )
