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 30
15-18 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
AMERICAN RECOVERY AND REINVESTMENT ACT (ARRA) REQUIREMENTS
See http://www.whitehouse.gov/omb/assets/a133_compliance/arra_addendum_1.pdf pages 29-53 and specific page references below
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 301
Cities and Counties must be registered in the Central Contractor Registration (CCR) database (https://www.bpn.gov/ccr/default.aspx), page 45 of 301
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
