Such matters as contractor integrity, technical capability, past performance, demonstrated commitment to environmentally responsible corporate practices, and financial and technical resources may be considered in determining responsible bids and awards. The agency shall maintain records detailing the significant history of procurement, including at a minimum: the solicitation, bids or proposals received, any applicable evaluation process documentation, the contract award, and any modifications thereto.
