NOTE: This guide specification covers the requirements for resilient athletic
flooring.
Edit this guide specification for project specific requirements by adding, deleting,
or revising text. For bracketed items, choose applicable items(s) or insert
appropriate information.
Remove information and requirements not required in respective project, whether
or not brackets are present.
Comments and suggestions on this guide specification are welcome and should
be directed to the technical proponent of the specification. A listing of technical
proponents, including their organization designation and telephone number, is
on the Internet.
Recommended changes to a UFGS should be submitted as a Criteria Change Request
(CCR).
This guide specification includes tailoring options for indoor-outdoor carpeting,
rubber composition tile, rubber poured-in-place flooring, sheet rubber composition
flooring, sheet vinyl composition flooring, urethane poured-in-place flooring,
and resilient mat underlay. Selection or deselection of a tailoring option

PART 1 GENERAL
NOTE: Systems specified in this guide specification are recommended for indoor
athletic rooms e.g., weight rooms, running tracks, recreational areas, aerobic
centers, multi-purpose gym floors, etc. Hardwood flooring is preferable for
basketball courts, handball, and racquetball courts. Rubber-base floorings
can be used in outdoor installations like wet bars, running tracks, tennis courts,
and swimming pool walks.

NOTE: Review submittal description (SD) definitions in Section 01 33 00 SUBMITTAL
PROCEDURES and edit the following list to reflect only the submittals required
for the project. Submittals should be kept to the minimum required for adequate
quality control.
A “G” following a submittal item indicates that the submittal requires Government
approval. Some submittals are already marked with a “G”. Only delete an existing
“G” if the submittal item is not complex and can be reviewed through the Contractor’s
Quality Control system. Only add a “G” if the submittal is sufficiently important
or complex in context of the project.
For submittals requiring Government approval on Army projects, a code of up
to three characters within the submittal tags may be used following the "G"
designation to indicate the approving authority. Codes for Army projects using
the Resident Management System (RMS) are: "AE" for Architect-Engineer; "DO"
for District Office (Engineering Division or other organization in the District
Office); "AO" for Area Office; "RO" for Resident Office; and "PO" for Project
Office. Codes following the "G" typically are not used for Navy, Air Force,
and NASA projects.
Choose the first bracketed item for Navy, Air Force and NASA projects, or choose
the second bracketed item for Army projects.
Government approval is required for submittals with a "G" designation; submittals not having a "G" designation
are for [Contractor Quality Control approval.][information only. When used, a designation following the "G"
