GSA Schedule for Engineering Firms: MAS vs. OASIS+
Engineering firms serving the federal government face a strategic choice: pursue the GSA Multiple Award Schedule (MAS), OASIS+, agency-specific IDIQs, or some combination. Each vehicle has different entry requirements, competitive dynamics, and market reach. For most engineering firms, the optimal strategy involves holding a Schedule for smaller engagements and pursuing OASIS+ or agency-specific vehicles for larger, more complex programs.
Engineering SINs on the MAS
Engineering services on the MAS are covered primarily through SINs in the Professional Services section. Environmental engineering, facilities engineering, systems engineering, and related technical disciplines may align with specific SINs. Some engineering disciplines may also be covered under SINs for technical consulting or IT (for software engineering and systems architecture). Review the solicitation carefully to identify which SIN description most accurately covers your engineering specialty.
OASIS+ for Complex Engineering Requirements
For multi-disciplinary engineering programs — environmental remediation projects combining engineering assessment with remediation design and construction oversight, or systems engineering programs combining technical architecture with program management — OASIS+ provides a better structural fit than the Schedule. OASIS+ is designed for complex, integrated requirements and has a pre-qualified vendor pool with demonstrated capabilities. The competitive process for OASIS+ is more rigorous than the Schedule, but the average task order size is significantly larger.
