The Contractor's accomplishment of these functions shall be measured by agreed upon performance standards. The PHA will consider proposals that use its office space (for a negotiated cost) and other related administrative systems OR proposals that have the major administrative activities based at another location. Proposers will have to identify which business model that they intend to use and explain in detail how program participants, landlords, applicants, and members of the public will be able to access the program. Proposals for off-site administration will have to explain how program integrity, confidentiality, record-keeping, and audit trail obligations will be met.
