Certificates of Authorization, if applicable

Provide us with updated copies of the certificates required for Area of Expertise (refer to services 1-11 on page one of the Consultant Registration form). Please make sure they will be current through the Fiscal Year.


Inter-company relationships

If your firm is a subsidiary to another firm or if your firm owns subsidiary firms please provide a description of the incorporation status of the firm(s) and a description of the relationship between your firm(s). We are primarily interested in situations where related companies could be involved on DelDOT projects.

Inter-company relationships are of a particular interest to us. We want to know what entity it is that we will be involved with should a procurement opportunity present itself. If a subsidiary company is operating under the umbrella of a parent company and yet still maintains a separate Federal I.D. number then that subsidiary should be registered with us separately. Please contact our office if you have any questions regarding this matter.

Current Overhead/Indirect Cost Rate

If available, please provide a copy of the firm's most recently audited rate. The rate may be as audited by a Federal or State audit agency or it may be prepared by the firm's accountant. Overhead costs should be determined per 48 Code of Federal Regulations (FARs) subpart 31 - Contracts with Commercial Organizations. We consider direct labor as the base for determining an acceptable overhead/indirect cost rate

It is not permissible to indicate that overhead/indirect cost information is unavailable. There must be some information provided to support an additive that represents those costs applicable for doing business as a consultant.

The burden of conformance with all licensing, regulatory, and statutory requirements to perform work for the Delaware Department of Transportation is the responsibility of the firm applying for registration.
