MODIFICATIONS AND MASS MODIFICATION GUIDANCE
The clauses below outline the different types of modifications that will happen
throughout the life of your contract. The main difference between modifications
and mass modifications is that modifications are generally initiated by you,
while mass modifications are those routinely generated by GSA and often
associated with a solicitation refresh. These two types of modifications are
used to keep your contract current and compliant.
MASS MODIFICATIONS
MAS Mass Modifications are issued directly to contractors via the mass mod
system. Mass Mods should be signed within 90 days of receipt. Each mass
modification will outline the significant changes impacting the solicitation and
your subsequent contract. Significant changes may vary depending on the
offerings on your contract. If you do not sign a mass modification prior to the
next modification release, the unsigned mass mod changes will roll into the new
Refresh mass mods. In other words, if you have not signed Refresh 2 by the time
Refresh 3 is released, when you sign Refresh 3 it will include changes from
Refresh 2 and 3.
Here is a breakdown of the significant changes associated with the MAS
Solicitation Refresh Mass Modifications:
FY 21 MAS Refresh Significant Changes [PDF - 93 KB]
CONTRACTOR INITIATED MODIFICATIONS
Key component: Understand when you need to initiate a modification for your
Schedule and when GSA will initiate modifications that may impact your Schedule.
MODIFICATIONS
* Review the following MAS solicitation clauses:
* 552.238-82 Modifications (Federal Supply Schedule) (Jan 2022) (Alternate I
- MAR 2020)
* 552.238-82 Modifications (Federal Supply Schedule) (Jan 2022) (Alternate II
- MAY 2019)
* GSA has developed a single MAS modification guidance, along with Price
Proposal Templates. This guidance includes all modification types available
in eMod and is meant to ensure that contractors are aware of the information
needed to successfully prepare and submit modification requests to their
Contracting Officer/Contracting Specialist (CO/CS). Please click below to
download the MAS modification guidance and Price Proposal Templates.
* MAS Modification Guidance [PDF - 2 MB]
* Sample Cover Letters [PDF - 303 KB]
GSA has developed these cover letters to assist contractors with the
information outlined in the MAS Modification Guidance. Multiple Award
Schedule (MAS) contract holders should fill in the information noted in
blue text for each sample submitted. These cover letters are samples
only; please customize according to your specific needs. Information can
be added and/or deleted as needed for each requested mod type.

* A modification is required whenever a change is made to your Schedule
contract. Most frequently, changes are made to products and/or services,
prices, or terms and conditions. However, modifications are also required for
administrative changes such as authorized negotiators, address(es), phone/fax
numbers, and key personnel. When initiated by the contractor, modification
requests must be submitted electronically using eMod by your company’s
Contracting Administrator, often referred to as the Point of Contact (POC).
For information specific to your Schedule, please visit the Vendor Support
Page, "Modification Options".
Should your firm need to modify your contract, please check your GSA Schedule
Offerings page to make sure you are not missing any specific instructions
related to your contract. Additionally, your company is responsible for
keeping all authorized negotiators and agent delegations up-to-date in the
system. For example, if you delegated pre-award responsibilities to a
consultant or third-party agent and do not intend for these agents to
represent your firm following contract award, you must specifically request
that these agents be removed as authorized negotiators from your contract.
Additional helpful information about processing modifications can be found
through the eOffer/eMod Help Center.
If you are a dealer/reseller of COTS products, and are adding a new
manufacturer to your existing contract, you must submit a Letter of Supply,
unless your manufacture participates in the Verified Products Portal (VPP);
if they are VPP participants, you do not need to provide a Letter of Supply.
GSA recommends checking the Verified Products Portal Participation Dashboard
to determine if your products come from a manufacturer participating in the
VPP. For more information about the Verified Products Portal, see attached
"MAS Contractor - VPP Implementation Q&A"d [PDF - 123 KB]
GENERAL CLAUSES
Key Component: The following clauses are generally applicable to all Schedule
contracts and should be clearly understood.
* Review clause 52.222-26 Equal Opportunity:
This clause requires that the Equal Opportunity Clause poster be displayed in
a conspicuous place available to employees and applicants for employment.
Subcontractors must similarly display the EEO poster. See the U.S. Equal
Employment Opportunity Commission website for various versions of this
poster. Contractors are also required to file the Equal Employment
Opportunity EEO-1 Survey in accordance with the instructions found at U.S.
Equal Employment Opportunity Commission Survey website.
* Review clause 52.204-9 Personal Identity Verification of Contractor
Personnel:
This clause requires your company to comply with agency personal identity
verification procedures identified in the contract that implement Homeland
Security Presidential Directive-12 (HSPD-12), Office of Management and Budget
(OMB) guidance M-05-24 and Federal Information Processing Standards
Publication (FIPS PUB) Number 201.

Traveler reimbursement is based on the location of the work activities and not
the accommodations, unless lodging is not available at the work activity, then
the agency may authorize the rate where lodging is obtained.
Unless otherwise specified, the per diem locality is defined as "all locations
within, or entirely surrounded by, the corporate limits of the key city,
including independent entities located within those boundaries."
Per diem localities with county definitions shall include"all locations within,
or entirely surrounded by, the corporate limits of the key city as well as the
boundaries of the listed counties, including independent entities located within
the boundaries of the key city and the listed counties (unless otherwise listed
separately)."
When a military installation or Government - related facility(whether or not
specifically named) is located partially within more than one city or county
boundary, the applicable per diem rate for the entire installation or facility
is the higher of the rates which apply to the cities and / or counties, even
though part(s) of such activities may be located outside the defined per diem
locality.
