According to GSA guidelines, contractors must align their SEPM proposals to agency sustainment priorities, show integrated life-cycle planning, and articulate measurable support outcomes. This opening guidance applies whether the RFP is issued by DoD, a civilian agency or a prime like Textron. Proposals should name the IPS elements they will satisfy — supply support, maintenance planning, product support management, technical data, sustaining engineering, and disposal planning — and provide a crosswalk to the Performance Work Statement (PWS). For aviation work (T-6 or similar), include specific airworthiness, configuration management, and depot-support sequencing. The contracting officer will evaluate the technical approach against the PWS’s success criteria and a cost/price realism assessment. The GSA expectation is concrete schedules, resource-loaded staffing matrices, and risk mitigation for obsolescence and spares. Include references to OMB and agency sustainment guidance where applicable, and highlight any small-business or socioeconomic credit (8(a), HUBZone, SDVOSB) that affects evaluation. This paragraph names GSA, DoD, and FAR and sets the baseline for what evaluators expect.
