B.1 GENERAL

The One Acquisition Solution for Integrated Services (OASIS)+ Multi-Agency Contract (MAC) is a Government-wide, multiple award, Indefinite Delivery, Indefinite Quantity (IDIQ) acquisition program for services. The program is designed to address agencies’ need for a full range of service requirements that integrate multiple service disciplines and ancillary services/products with the flexibility for commercial and non-commercial requirements, all contract types and pricing determined at the task order level to achieve a total solution. New services may be added to this contract throughout the life of the program and procedures are found in Section H.18. The Contractor shall provide all management, supervision, labor, facilities and materials necessary to perform each requirement solicited through the contract on a task order basis.

Hereafter, the family of OASIS+ services contracts will also be referred to as the “Master Contract(s).” The OASIS+ family of contract programs includes the following contract vehicles:

1) Unrestricted (UR) Contract

2) 100 percent Small Business (SB) Set-aside Contract

3) 100 percent Women-Owned Small Business (WOSB) Set-aside Contract

4) 100 percent 8(a) SB Set-aside Contract

5) 100 percent Service-Disabled Veteran-Owned Small Business (SDVOSB) Set-aside Contract

6) 100 percent Historically Underutilized Business Zone (HUBZone) SB Set-aside Contract

Each individual Master Contract contains shared terms and conditions and specific terms and conditions unique to the Contractor’s socioeconomic status (e.g., 8(a) and Small Business) and Domains. The term “Domain” is defined in Section C.2. Task orders issued under the OASIS+ program Master Contracts may hereafter be referred to as “Orders.”

The OASIS+ SB Master Contract includes twelve Domains. The Enterprise Solutions Domain is only included in the Unrestricted Contract, and therefore not available for use within the OASIS+ SB set-aside Master Contracts. In accordance with Section H.18, Adjustment of Scope Under the OASIS+ Master Contract, additional Domains may be added during the life of the contract.

Additionally, during the life of the OASIS+ program, the scope of Domains may be adjusted or removed from the contract program entirely, as determined appropriate by the Government.

B.2 AUTHORITY

The Administrator of the U.S. General Services Administration (GSA) is specifically authorized to purchase supplies and non-personal services, or in the case of OASIS+ establish government-wide contracts to allow the purchase of supplies and non-personal services, on behalf of other agencies under the Federal Property and Administrative Services Act (40 USC

501). In accordance with Federal Acquisition Regulation (FAR) 17.502-2 (GSA Class Deviation Revolutionary FAR Overhaul (RFO)-2025-17), the Economy Act does not apply to task orders awarded under OASIS+ under the authority of 40 USC 501.

The Master Contract is available for use by executive agencies and other entities as listed in GSA Order Open Government Partnership (OGP) 4800.2I, Eligibility to Use GSA Sources of Supply and Services; and any future versions of that directive (e.g., OGP 4800.2J, OGP 4800.2K). Listings of eligible entities by category are publicly available and accessible for review on GSA’s website:

https://www.gsa.gov/policy-regulations/policy/acquisition-policy/eligibility-determinations.

B.3 TOTAL SOLUTION

The Master Contract is designed to be a total solution vehicle for services, allowing commercial and non-commercial solutions at the task order level. Total solution is defined as any combination of direct supplies and services, as well as ancillary supplies and services, that are integral and necessary to the service-based requirements within the scope of the Master Contract and task order award.

For example, a total solution may include any combination of contract types and labor associated with Contiguous United States (CONUS) labor, Outside CONUS (OCONUS) labor, specialized labor, construction wage rate requirements, professional labor, service contract labor standards covered labor, and other costs such as subcontracts, travel, supplies, materials, equipment, special test equipment, and special tooling.

At the task order level, the Contractor should propose and identify the type of labor and other costs separately in its cost/price proposal and the Ordering Contracting Officer (OCO) should, when appropriate, identify the type of labor and other costs by a separate Contract Line Item Number (CLIN) in the task order award.

B.4 MINIMUM CONTRACT GUARANTEE AND MAXIMUM CONTRACT CEILING

(a) Minimum Guarantee. The minimum guaranteed task order award amount for this IDIQ contract is $2,500.00 per contract for the full term of the Master Contract. The exercise of the option period or an authorized novation does not establish an additional minimum guaranteed award amount.

(b) The Government has no obligation to issue task orders to the Contractor beyond the amount specified in paragraph (a) of this section. Should the contract expire, be canceled, or be unilaterally terminated for convenience by the Government without the Contractor having received task order award(s) valued at the minimum guaranteed award amount, the Contractor may present a payment request form to the Contracting Officer for an amount not to exceed the minimum guaranteed award amount. The minimum guaranteed award amount is not applicable and will not be paid if the contract is: terminated for default; unilaterally canceled at the request of the Contractor; off-ramped due to Contractor non-compliance, novation, duplicate contract, or as otherwise determined by the Contracting Officer. Additionally, in compliance with Section G.3.1.2, the Contractor must provide demonstrated evidence of submission for all responsive unsuccessful offers submitted under the Master Contract (e.g., record of response correspondence). If there were no task order solicitations issued under the CLINs held by the Contractor and, therefore, the Contractor was unable to submit a task order proposal, the Contractor may provide a statement to that effect. A payment request form will be provided by the OASIS+ Contracting Officer to applicable contractors.

(c) Maximum Ceiling. As authorized by CD-2023-01, there is no maximum dollar ceiling for the Master Contract or for each individual task order. An unlimited number of task orders, at any dollar value, may be placed for the term of the OASIS+ contract, including the option, if exercised. OCOs will follow applicable regulatory and agency requirements to establish maximum dollar ceilings at the task order level.

B.5 PERFORMANCE-BASED REFERENCE

Pursuant to FAR 37.101-1 (GSA Class Deviation RFO-2025-37), OASIS+ task orders allow for performance-based acquisition methods to the maximum extent practicable using the following order of precedence:

1. A Firm-Fixed Price Performance-Based Task Order

2. A Performance-Based Task Order that is not Firm-Fixed Price

3. A Task Order that is not Performance-Based

B.6 TASK ORDER CONTRACT TYPES

FAR part 16 (GSA Class Deviation RFO-2025-16) identifies types of contracts and agreements.

For OASIS+ task orders, allowable contract types include:

● FAR Subpart 16.2 Fixed-Price Contracts

● FAR Subpart 16.3 Cost-Reimbursement Contracts

● FAR Subpart 16.4 Incentive Contracts

● FAR 16.601 Time-and-Materials Contracts

● FAR 16.602 Labor-Hour Contracts

Task orders may also incorporate FAR 16.507-2(c)(3), Blanket Purchase Agreements (BPAs), (GSA Class Deviation RFO-2025-16) FAR subpart 17.1, Multiyear Contracting, (GSA Class Deviation RFO-2025-17) and FAR subpart 17.2, Options (GSA Class Deviation RFO-2025-17).

OASIS+ supports both commercial and non-commercial requirements. OASIS+ does not allow agreements identified in FAR subpart 16.7 (GSA Class Deviation RFO-2025-16).

These contract types can be used individually or in combination within a single task order comprising multiple CLINs.

For cost-reimbursement type task orders, the accounting system requirements at Section G.3.1.9.1 will apply.

B.7 TASK ORDER PRICING (ALL ORDER TYPES)

OASIS+ SB provides all Federal agencies the flexibility to determine fair and reasonable pricing tailored to the ordering agency’s requirement dependent upon level of competition, risk, uncertainties, complexity, urgency, and contract type. The OCO has the authority and responsibility for the determination of cost or price reasonableness for their agency’s task order requirements. Adequate price competition at the task order level, in response to an individual requirement, establishes the most accurate, fair, and reasonable pricing for that requirement.

The OCO must identify the applicable contract type for all CLINs in each OASIS+ SB task order.

See Section B.8.6 for ceiling rates for time-and-materials (T&M) and labor-hour (LH) Task Orders.

B.8 LABOR CATEGORIES

The Master Contract provides the flexibility to utilize labor categories for CONUS, OCONUS, specialized labor, construction wage rate requirements, professional services, service contract labor standards, or any combination thereof, at the task order level. The OCO is the authority in establishing what kind of labor is appropriate for each task order requirement.

OCOs have the following flexibilities regarding labor categories that may be utilized:

1. OASIS+ standardized labor categories; or

2. Contractor proposed custom or specialized labor categories that are non-standard; or

3. OCO-directed, non-standard custom or specialized labor categories that are customized to the requirement.

B.8.1 CONUS Standardized Labor Categories

CONUS labor is defined as in-scope labor being performed in the 48 contiguous states plus the District of Columbia.

The Master Contract provides for standardized labor categories in CONUS for utilization at the task order level. CONUS standardized labor is defined as all labor for which the expertise required or duties performed are within the scope of the Master Contract and task order in accordance with labor categories set forth in Attachment J-1, OASIS+ Labor Categories and Bureau of Labor Statistics Standard Occupational Classifications.

CONUS standardized labor categories correspond to the Office of Management and Budget’s (OMB) Standard Occupational Classification (SOC) for which the Bureau of Labor Statistics (BLS) maintains compensation data at www.bls.gov. CONUS standardized labor categories are individual labor categories that are mapped to a single SOC and functional description.

The Contractor may propose CONUS standardized labor when proposing a total solution;

however, the OCO will determine whether circumstances merit the use of CONUS standardized labor. CONUS standardized labor categories are encouraged but not mandatory for use at the task order level. The OCO should indicate in the task order solicitation whether or not Contractors shall submit labor pricing using the Master Contract’s CONUS standardized labor categories in their task order proposals. If non-standardized labor categories are used at the task order level, the Contractor is required to map awarded labor categories to the standardized labor categories when reporting in accordance with Section G.3.2.4 and the seniority levels in Attachment J-1 (e.g. Junior, Journeyman, Senior, Subject Matter Expert (SME)).

The Contractor shall be proficient in the use of the BLS SOC system and CONUS standardized labor categories identified in Attachment J-1, OASIS+ Labor Categories and Bureau of Labor Statistics Standard Occupational Classifications, in support of submitting cost/price proposals under task order solicitations that require CONUS standardized labor category submissions.

B.8.2 OCONUS Labor

OCONUS is defined as in-scope labor being performed outside the 48 contiguous states plus the District of Columbia. OCONUS labor is defined as all labor for which the expertise required or duties performed are within the scope of the Master Contract and task order. The Contractor may propose OCONUS labor when proposing a total solution; however, the OCO will determine whether circumstances merit the use of OCONUS labor. If non-standardized labor categories are used at the task order level, the Contractor is required to map awarded labor categories to the standardized labor categories when reporting in accordance with Section G.3.2.4 and the seniority levels in Attachment J-1 (e.g. Junior, Journeyman, Senior, Subject Matter Expert

(SME)).

The U.S. Department of State’s Bureau of Administration, Office of Allowances, publishes quarterly report indexes of living costs abroad, per-diem rate maximums, quarter’s allowances, hardship differentials, and danger pay allowances. The Department of State Standardized Regulations (DSSR) is the controlling regulation for allowances and benefits available to all U.S.

Government civilians assigned to foreign areas. Contractor civilians assigned to foreign areas https://aoprals.state.gov/content.asp?content_id=282&menu_id=101 https://aoprals.state.gov/content.asp?content_id=282&menu_id=101 may receive the allowances and benefits in the DSSR, but they shall not receive allowances and benefits in excess of those identified in the DSSR.

For OCONUS task orders where costs are not specifically addressed in the DSSR, the Government will reimburse the Contractor for all reasonable, allowable, and allocable costs in accordance with FAR part 31, Contract Cost Principles and Procedures (GSA Class Deviation RFO-2025-31), and other applicable regulatory supplements.

B.8.3 Custom or Specialized Labor

Custom or specialized labor is defined as any labor for which the expertise required or duties performed are within the scope of the Master Contract and task order, but are not identified by the standardized labor categories.

When CONUS standardized labor categories are not mandatory or not able to be mapped directly by the Contractor, the Contractor may propose specialized labor when proposing a total solution; however, the OCO will determine whether circumstances merit the use of specialized labor.

B.8.4 Construction Wage Rate Requirements

When labor for construction, alteration and repair are within the scope of the task order, construction wage rate requirements shall be implemented in accordance with FAR subpart 22.4 (GSA Class Deviation RFO-2025-22) and other regulatory supplements, as applicable. The OCO shall identify such work in the task order solicitation and make a determination as to whether wage determinations are to be applied.

The Department of Labor (DOL) is responsible for issuing wage determinations reflecting prevailing wages, including fringe benefits. Determinations are issued for different types of construction, such as building, heavy, highway, and residential (referred to as rate schedules), and apply only to the types of construction designated in the determination.

The Master Contract includes a list of clauses and/or provisions at Section I.1.2 that flow down to the task order level when construction, alteration, and repairs are within the scope of the task order. The OCO shall incorporate any additional appropriate clauses and provisions in each task order solicitation and subsequent award when construction, alteration, and repairs are within the scope of the Master Contract and task order requirement. When applicable, the OCO shall incorporate wage determinations subject to construction wage rate requirements in the task order award.

B.8.5 Service Contract Labor Standards

When Service Contract Labor Standards (SCLS) are within the scope of the Master Contract and task order, wage rate requirements shall be implemented in accordance with FAR subpart

22.10 (GSA Class Deviation RFO-2025-22) and other applicable regulatory supplements. The OCO shall identify such work in the task order solicitation and make a determination as to whether wage determinations are to be applied.

The DOL is responsible for issuing wage determinations reflecting prevailing wages, including fringe benefits. Contractors performing on task orders where service contract labor standards apply shall pay their employees at least the wages and fringe benefits found by the DOL to prevail in the locality of the work being performed, the Fair Standards Labor Act, and/or any applicable collective bargaining agreement.

The Master Contract includes a list of clauses and/or provisions at Section I.1.2 that flow down to SCLS-applicable task orders. The OCO shall incorporate any additional appropriate clauses and provisions in each task order solicitation and subsequent award when service contract labor standards apply. When applicable, the OCO shall incorporate wage determinations subject to wage rate requirements in the task order award.

B.8.6 Requirements For Labor Under Time & Material and Labor Hour Task Orders

When preparing solicitations for commercial or non-commercial T&M and/or LH type task orders, the OCO shall incorporate one of the following provisions in the task order solicitation.

a. FAR 52.216-29 Time-and-Materials/Labor-Hour Proposal Requirements—Non- Commercial Item Acquisition with Adequate Price Competition. For Department of Defense (DoD) requirements, when selecting FAR 52.216-29, the OCO shall also select Defense Federal Acquisition Regulation Supplement (DFARS) 252.216-7002, Alternate A Time-and-Materials/Labor-Hour Proposal Requirements – Non-Commercial Item Acquisition with Adequate Price Competition

b. FAR 52.216-30 Time-and-Materials/Labor-Hour Proposal Requirements—Non- Commercial Item Acquisition without Adequate Price Competition

c. FAR 52.216-31 Time-and-Materials/Labor-Hour Proposal Requirements— Commercial Item Acquisition

T&M and LH task orders require labor categories and their associated rates to be identified in the task order award document. T&M and LH task orders with subcontracts that do not specify a labor category in the task order shall be proposed and awarded as Materials in accordance with FAR 52.232-7, Payments under Time-and-Materials and Labor-Hour Contracts.

When the provision FAR 52.216-30,Time-and-Materials/Labor-Hour Proposal Requirements--Non Commercial Item Acquisitions Without Adequate Price Competition is selected or; FAR 52.216-31, Time-and-Materials/Labor-Hour Proposal

Requirements--Commercial Item Acquisition is selected and there is an exception to fair opportunity, the OASIS+ SB IDIQ establishes maximum allowable labor rates in the form of fully burdened ceiling rates for certain non-custom, CONUS, T&M/LH labor for both Government and Contractor Sites. Based on the specific task order requirements, the OCO is authorized to exceed the OASIS+ SB ceiling rates for those labor categories that include Secret/Top Secret/Sensitive Compartmented Information (SCI) labor and/or OCONUS locations, if necessary.

The ceiling rates do not apply when the provision FAR 52.216-29 Time-and-Materials/ Labor-Hour Proposal Requirements—Non-Commercial Item Acquisition With Adequate Price Competition is selected or; FAR 52.216-29 with DFARS 252.216-7002, Alternate A, is selected or; FAR 52.216-31, Time-and-Materials/Labor-Hour Proposal Requirements-Commercial Item Acquisition is selected and there is not an exception to fair opportunity.

In order to determine future year T&M/LH ceiling rate pricing, the originally awarded rates will have an escalation factor applied. This escalation factor will be the average of the annual Bureau of Labor Statistics (BLS) Employment Cost Index (ECI) for the previous three years (Wages and salaries for Private industry workers in All industries and occupations, 12-month percent change).

The OASIS+ SB ceiling rates that are in effect at the time a task order is awarded shall remain with the task order award during the entire term of the task order, including task orders with option periods.

See Section F.3, Period of Performance, for the OASIS+ SB IDIQ and task orders awarded under the master contract.

B.9 TRAVEL PRICING (ALL ORDER TYPES)

Travel may be required to support the requirements of this contract and as stated in individual task orders. For those task orders requiring travel, the Contractor must include estimated travel requirements in the task order proposal as required by the OCO. All travel shall be in accordance with the Federal Travel Regulation (FTR) [as applicable] and all lodging shall be at or below allowable, published lodging rates for the respective locality, unless an exception applies. The Contractor is required to ensure good stewardship of travel funds, and shall seek rates lower than the approved FTR lodging rates whenever possible.

B.10 WORK OUTSIDE THE CONTIGUOUS UNITED STATES

It is anticipated there may be task orders under this Master Contract with performance OCONUS. The DSSR is the controlling regulations for allowances and benefits available to all

U.S. Government civilians assigned to foreign areas. OCOs are authorized to select a foreign area pricing approach consistent with the DSSR tailored to their order requirements.

If a task order request for proposal (TORFP) includes foreign area work and the OCO has not identified a preferred foreign area pricing approach, Contractors may include a foreign area pricing approach consistent with the DSSR in their response to a TORFP. OCOs will determine if the approach results in a fair and reasonable price in accordance with the DSSR, FAR subpart 15.4, Contract Pricing (GSA Class Deviation RFO-2025-15), and FAR part 16, Types of Contracts (GSA Class Deviation RFO-2025-16) as applicable. Upon request of the OCO, the Contractor must provide data other than certified cost or pricing data (FAR 15.403-1 (GSA Class Deviation RFO-2025-15)) to support its task order proposal(s).

B.11 OASIS+ CONTRACT ACCESS FEE

GSA’s operating costs are reimbursed through a Contract Access Fee (CAF) charged on all orders placed against the Master Contract. The CAF is paid by the ordering agency but remitted to GSA by the Contractor. GSA maintains the unilateral right to establish and change the CAF rate. GSA will provide at least a 60-day notice prior to the effective date of any change to the CAF rate or payment process.

The CAF rate, which is currently 0.15%, is applied to the total amount billed on each invoice (including ancillary support, travel, and profit).

Using the established CAF rate, the Contractor must include the estimated CAF in each task order proposal based on the total estimated order value. The Contractor must include the CAF as a separate line item on all proposals and invoices to the Government, regardless of contract type. The CAF is established by GSA, and must never be treated as a negotiable element between the Contractor and the ordering agency. If the Contractor does not ensure a separate CAF CLIN is included in its task order proposal and resulting task order award, the Contractor shall still be liable to pay the owed CAF to the Government.

B.12 OASIS+ SUBMISSION PORTAL

The OASIS+ Submission Portal (OSP) is a software application the Government intends to use for OASIS+ proposal submission and proposal evaluation. The Government reserves the right to change systems related to the solicitation, evaluation, award and administration of the OASIS+ contracts at any time during the life of the program.

SECTION C – DESCRIPTION/SPECIFICATIONS/STATEMENT OF WORK

C.1 SCOPE

The objective of this contract is to provide Government agencies with total integrated solutions for a multitude of services-based requirements on a global basis. These services requirements may call for solutions that cross multiple disciplines, include ancillary support, may be commercial and/or non-commercial, using a variety of contract types including fixed price (all types), cost reimbursement (all types), time and materials/labor hour, or a hybrid mix of contract types.

This contract is available for use by all Federal agencies and other entities listed in GSA Order ADM 4800.2I, Eligibility to Use GSA Sources of Supply and Service as amended.

The contract scope is organized by Domains. The term Domain refers to functional groupings of related services spanning multiple North American Industry Classification System (NAICS) Codes. Domains are designed to align order requirements to qualified industry partners. GSA may introduce new Domains at its discretion as detailed in Sections C.3 and H.11. When issuing task order solicitations, the OCO will select (1) the Domain best aligned to their requirements and (2) the NAICS under that Domain best aligned to the principal purpose of the work. The chosen order-level NAICS will determine the size standard based on the awardee’s size at the time of the IDIQ offer for that NAICS, unless the OCO’s order solicitation explicitly requires a size re-representation from all offerors at the order level.

C.1.1 North American Industry Classification System

Pursuant to 13 CFR § 121.402(c)(1)(ii), multiple NAICS Codes and corresponding SB size standards are assigned to this contract (at the master contract level) as detailed in section C.2.

Each Domain is limited to the NAICS Codes specifically listed under that Domain.

OASIS+ Solicitation NAICS Code: For administrative purposes only, the OASIS+ Solicitation is assigned a single NAICS Code (541990) which represents the preponderance scope of the OASIS+ Contract Program as a whole.

OASIS+ Primary NAICS Codes Assigned at the Individual Master Contract Level: The OASIS+ process of NAICS Code assignment at the individual Master Contract level is for administrative purposes, and will ensure proper socioeconomic and size status reporting at the task order level. Due to a limitation with the Federal Procurement Data System (FPDS), only a single NAICS Code may be assigned to a contract and subsequently reported with each contract action (i.e., task order); therefore, each Contractor will be assigned a single Primary NAICS Code to its Master Contract based on its awarded Domains (CLINs). The Primary NAICS Code for all OASIS+ SB contracts will be selected and assigned based on the largest size standard within its awarded Domains. When the OASIS+ Contracting Officer (CO) assigns a Primary NAICS Code, employee-based size standards take precedence over NAICS Codes based on annual receipts. See Section M.3 for a limited exception to this rule. This is critical to ensure Contractors are not locked out of Domain fair opportunity during re-representation in accordance with Section G.3.1.7.2, as long as they are otherwise eligible based on their size standard at time of re-representation. This Primary NAICS Code will be reflected in each awarded contract and associated FPDS record. However, assignment of a Primary NAICS Code does not limit Contractors’ eligibility to respond to task order solicitations or perform work outside of the NAICS Code assigned as their Primary NAICS Code on their contract.

Contractors will be eligible to compete for applicable task orders within all awarded CLINs (NAICS Codes), which represent the Contractor’s specific fair opportunity pools. Fair opportunity will be managed in eBuy, which is the mandatory, sole system for OCOs to issue task order solicitations. The Contractor will only be included in and allowed to compete under the CLINs (NAICS Codes) where they (and their proposed team, as applicable) represented (and subsequently re-represent) as a small business concern for the corresponding size standard at the time of offer submission in accordance with (IAW) 13 CFR 121.404, and are otherwise eligible under the socioeconomic contract vehicle. Refer to Section H.11.3 for how the addition of team members under an Add Domain Modification request could affect team size.

Example: Contractor ABC submits a proposal for consideration under the OASIS+ SB solicitation for three Domains:

● Technical and Engineering Domain

● Research and Development

● Intelligence Services

Contractor ABC qualifies for and is awarded all CLINs within the three Domains. Among Contractor ABC’s awarded Domains, the largest receipts-based size standard is $47.0M (541330 exceptions), and the largest employee-based size standard is 1,500 employees (541715 exceptions). Refer to the NAICS Codes and size standards in the table at Section C.2.

Contractor ABC would be assigned NAICS Code 541715 with a corresponding size standard of 1,500 employees to their Master Contract. NAICS Code 541715 would be reflected in their Master Contract FPDS record and all task orders awarded under this Master Contract. This assigned NAICS Code would not limit Contractor ABC’s eligibility to respond to task order solicitations or perform work outside of its assigned Primary NAICS Code. Contractor ABC would be eligible to compete for and be awarded task orders in the Technical and Engineering Domain, Research and Development Domain, and Intelligence Services Domain.

Once Federal regulations and systems can accommodate, GSA anticipates issuing a mass modification to all awarded contracts in accordance with Section H.19 to include the assignment of multiple NAICS Codes and corresponding size standards under each Master Contract in

FPDS.

As part of initial proposal submission, GSA is requiring all Offerors, including any proposed team members, to represent their size status for each NAICS Code within all of their proposed Domain(s), including NAICS Code exceptions where applicable, to ensure fair opportunity within each CLIN. Offerors will be awarded only the CLINs in which the entity, including all proposed team members across all Domain submissions, represents that it is a small business concern for the size standard corresponding with the NAICS Code assigned to each CLIN. The awarded CLINs represent the fair opportunity pools in which the awardee may compete. Offerors will not be awarded any CLINs in which they represent their size as other than small unless an exception to affiliation exists as set forth in 13 CFR § 121.103(b). The chosen order-level CLIN will determine the NAICS Code and corresponding size standard based on the awardee’s size at the time of IDIQ offer (or most recent Master Contract rerepresentation) for that NAICS Code, unless the OCO’s task order solicitation explicitly requires a size re-representation from all Offerors at the order level.
