GSA OASIS+ (One Acquisition Solution for Integrated Services Plus) is widely considered the most significant government-wide acquisition contract (GWAC) for professional services in federal history. With an estimated $90B+ in potential value over its life, OASIS+ represents a once-in-a-generation opportunity for professional services contractors to position themselves for decades of federal work.
In this comprehensive guide, we'll break down everything contractors need to know about OASIS+ — the pool structure, application requirements, scoring methodology, and the strategies that maximize your probability of award.
What is OASIS+?
OASIS+ is GSA's successor to the OASIS contract, designed to consolidate professional services procurement across the federal government into a single, streamlined contract vehicle. It covers a wide range of professional services including management consulting, technical services, engineering, scientific research, financial services, and logistics.
OASIS+ is an IDIQ (Indefinitely Delivery/Indefinitely Quantity) contract, meaning it doesn't guarantee any work — it simply qualifies you to compete for task orders issued by participating federal agencies. But with over $90B in potential spending, even a small share of OASIS+ task orders represents a significant revenue opportunity.
Pool Structure
OASIS+ is organized into seven pools, each covering different domains of professional services:
- Pool 1: Management and Advisory
- Pool 2: Technical and Engineering
- Pool 3: Research and Development
- Pool 4: Intelligence
- Pool 5: Environmental
- Pool 6: Facilities
- Pool 7: Logistics
Contractors can apply for any pool where they can demonstrate relevant experience. Applying for more pools increases your access to federal task orders, but also requires more evidence of capability.
The Self-Scoring Worksheet
OASIS+ uses a unique self-scoring model where contractors score themselves against a structured worksheet and then support each claimed score with documentation. GSA validates your scores and awards contract positions to the highest-scoring offerors in each pool (up to a maximum number of awards per pool).
The Self-Scoring Worksheet evaluates contractors across several scoring categories, including:
- Relevant experience (project citations with dollar values and complexity)
- Key personnel qualifications and certifications
- Corporate certifications and recognition
- Financial stability indicators
- Past performance quality ratings
Maximizing Your Score: Key Strategies
Given OASIS+'s competitive nature, maximizing your self-score is critical. Here are the most impactful strategies:
1. Project Citation Selection
Project citations are the single highest-scoring element of most OASIS+ applications. Select projects that maximize the scoring metrics — focusing on total contract value, relevance to the pool's domain, and complexity indicators such as multi-agency work, multi-site operations, and large team sizes.
2. Key Personnel Certifications
OASIS+ awards points for key personnel with industry-recognized certifications. Ensure your proposed personnel hold the highest-scoring certifications for each pool — PMP, CAPM, CISA, CISSP, PE, and others depending on the pool domain.
3. Past Performance Ratings
Only citations with excellent past performance ratings (CPARS ratings of "Exceptional" or "Very Good") should be included. Marginal ratings may actually hurt your competitive position relative to competitors who select only their strongest references.
