Award is anticipated within 7 days of the date quotes are due. This procurement is being conducted under the Simplified Acquisition Procedures. An ombudsman has been appointed to hear concerns from offerors, potential offerors, and contractors during the preaward and postaward phases of this acquisition. The purpose of the ombudsman is not to diminish the authority of the contracting officer, the Source Evaluation Board, or the selection official, but to communicate concerns, issues, disagreements, and recommendations of interested parties to the appropriate Government personnel and to work to resolve them. When requested, the ombudsman will maintain strict confidentiality as to the source of the concern. The ombudsman does not participate in the evaluation of proposals, the source selection process, or the adjudication of formal contract disputes. Concerned parties may call the installation ombudsman Belinda Adams at 757-864-8989. DO NOT CALL THE OMBUDSMAN FOR SOLICITATION REQUESTS/INFORMATION. Concerns, issues, disagreements, and recommendations which cannot be resolved by the installation ombudsman may be referred to the NASA Agency ombudsman Tom Luedtke at 202-358-2090. Before consulting with any ombudsman, interested parties must try to resolve their concerns with the contract specialist or the contracting officer. For solicitation requests/information, contact the point of contact (POC) listed at the beginning of this synopsis. (0185)
