a) An Affidavit of Availability (Form BC-57) is attached to the Transportation Bulletin and must be submitted with a request for Authorizations to Bid. It is a sworn statement concerning the contractor's present and pending contract commitments. The contractor shall not omit or misrepresent its work outstanding. When the contractor has uncompleted or pending work as a party of a joint venture, the contractor's responsible portion of the work shall be shown. The affidavit shall be signed by an officer or director of a corporate contractor, and otherwise, an owner shall sign. The affidavit is not required when Authorization to Bid is not being requested. The affidavit shall include:
d) A contractor may request to forego filing an affidavit if it has a financial rating at either of the following levels. The Prequalification Section will grant such a request provided the contractor's existing contracts with the Department are not behind approved contract progress schedules and provided the most recent performance evaluation rating is not less than 6.0 in the performance factor calculation. (See Section 650.240 of this Part.)
