payments, statements, and similar requirements associated with regulations, codes, and
standards.
B.
The term "Regulations" is defined to include laws, statutes, ordinances, and lawful orders issued
by governing authorities, as well as those rules, conventions, and agreements within the
construction industry which effectively control the performance of the work regardless of whether
they are lawfully imposed by governing authority or not.
1.3
DEFINITIONS
A.
General Explanation: Certain terms used in Contract Documents are defined in this Article.
Definitions and explanations contained in this Section are not necessarily complete, but are
general for the work to extent that they are not stated more explicitly in another element of the
Contract Documents.
B.
General Requirements: Provisions and requirements of other Division 1 Sections apply to the
entire work of the Contract and, where so indicated, to other elements which are included in the
project.
C.
Indicated: The term "indicated" is a cross-reference to graphic representations, notes, or
Schedules on the Drawings, to other paragraphs or schedules in the Specifications, and to
similar means of recording requirements in Contract Documents. Where terms such as
"shown," "noted," "scheduled," and "specified" are used in lieu of "indicated," it is for the purpose
of helping the reader locate the cross-reference, and no limitation of location is intended except
as specifically noted.
D.
Directed, Requested, Etc.: Terms such as "directed," "requested," "authorized," "selected,"
"approved," "required," "accepted," and "permitted" mean "directed by the Engineer," "requested
by the Engineer," and similar phrases. However, no such implied meaning will be interpreted to
extend the Engineer's responsibility into the Contractor's area of construction supervision.
E.
Approve: Where used in conjunction with the Engineer's response to submittals, requests,
applications, inquiries, reports, and claims by the Contractor, the term "approved" will be held to
limitations of the Engineer's responsibilities and duties as specified in General and
Supplementary Conditions. In no case will the Engineer's approval be interpreted as a release
of the Contractor from responsibilities to fulfill requirements of Contract Documents or
acceptance of the work, unless otherwise provided by requirements of the Contract Documents.

Installer: The "installer" is "the entity" (person or firm) engaged by the Contractor, its
subcontractor, or sub-subcontractor for performance of a particular element of construction at
the project site, including installation, erection, application, and similar required operations. It is
a requirement that installers are experienced in the operations they are engaged to perform.
K.
Testing Laboratory: A "testing laboratory" is an independent entity engaged to perform specific
inspections or tests of the work, either at the project site or elsewhere, and to report and (if
required) interpret results of those inspections or tests.
1.4
INDUSTRY STANDARDS
A.
Applicability of Standards: Except where more explicit or stringent requirements are written into
the Contract Documents, applicable construction standards have the same force and effect as if
bound into or copied directly into the contract documents. Such industry standards are made a
part of the Contract Documents by reference. Individual specification sections indicate which
codes and standards the Contractor must keep available at the project site for reference.
B.
Referenced standards (standards referenced directly in the contract documents) take
precedence over standards that are not referenced but generally recognized in the industry for
applicability to the work.
C.
Unreferenced Standards: Except as otherwise limited by the Contract Documents, standards
not referenced but recognized in the construction industry as having direct applicability will be
enforced for performance of the work. The decision as to whether an industry code or standard
is applicable, or as to which of several standards are applicable, is the sole responsibility of the
Engineer.
D.
Publication Dates: Except as otherwise indicated, where compliance with an industry standard
is required, comply with standard in effect as of date of Contract Documents.
E.
Conflicting Requirements: Where compliance with two or more standards is specified,
and where these standards establish different or conflicting requirements for minimum quantities
or quality levels, the most stringent requirement will be enforced, unless the contract documents
specifically indicate otherwise. Refer requirements that are different, but apparently equal, and
uncertainties as to which quality level is more stringent to the Engineer for a decision before
proceeding.
F.
Minimum Quantities or Quality Levels: In every instance, the quantity or quality level shown or
specified is intended to be the minimum to be provided or performed. Unless otherwise
indicated, the actual work may either comply exactly, within specified tolerances, with the
FA4608-16-R-0013
Attachment 1
Page 10 of 79
minimum quantity or quality specified, or may exceed that minimum within reasonable limits. In
complying with these requirements, the indicated numeric values are minimum or maximum
values, as noted, or as appropriate for the context of the requirements. Refer instances of
uncertainty to the Engineer for decision before proceeding.
G.
Copies of Standards: The contract documents require that each entity performing work be
experienced in that part of the work being performed. Each entity is also required to be familiar
with industry standards applicable to that part of the work. Copies of applicable standards are
not bound with the contract documents.
H.
Where copies of standards are needed for proper performance of the work, the Contractor is
required to obtain such copies directly from the publication source.
I.
Although copies of standards needed for enforcement of requirements may be required
submittals, the Engineer reserves the right to require the Contractor to submit additional copies
as necessary for enforcement of requirements.
J.
Abbreviations and Names: Trade association names and titles of general standards are
frequently abbreviated. Where acronyms or abbreviations are used in Specifications or other
Contract Documents they are defined to mean the recognized name of the trade association,
standards generating organization, governing authority or other entity applicable to the context of
the text provision. Refer to the "Encyclopedia of Associations," published by Gale Research
Co., available in most libraries.
