A/E Consultant & Subconsultant Resources


The following describes SCDOT's requirements for annual submissions by A/E Consultants. All consultants and subconsultants with active contracts or proposing to provide engineering and design related services (as defined in 23 U.S.C. §112(b)(2)(A), 23 CFR §172.3, 40 U.S.C. §1102 and state laws and regulations) for Federal-aid projects to SCDOT and its sub-recipients must submit the following information for review by the SCDOT Office of Contract Assurance (OCA):

  • Copies of cognizant or acceptance letters from other State DOTs and/or provisional billing rates approved by the DCAA
  • Executive Compensation Analysis
  • Audited, reviewed, compiled, or internally-prepared financial statements.
  • Trial Balance (If Schedule of Indirect Costs is unaudited)
  • Current Chart of Accounts
  • Sample Timesheets
  • Written policies and Procedures, as indicated in ICQ questions B.3, D.1, & I.1.b. (Provide all policies/procedures updated after December 31, 2020.)

Firms that have never received an approved indirect cost rate by a cognizant agency or do not have relevant or sufficient contract cost history to use as a base may apply for the SCDOT Safe Harbor indirect cost rate of 110% for use on projects until the firm has developed sufficient cost history to develop its own FAR compliant indirect cost rate. Firms applying for the Safe Harbor rate must meet established criteria, as provided by the OCA. The expectation for firms approved for the Safe Harbor rate will be for the firm to establish a cost history for the eventual development of an indirect cost rate based on the actual costs of the firm and in accordance with federal cost principles. Contact the OCA at 803-737-237 for information on the Safe Harbor indirect cost rate.

Required information should be submitted as soon as it is available, but no later than 180 days after the end of the firm's fiscal year:
