Ultimate Treatment (Historic Structure Report)
A general definition of a structure's development limits based on considerations of use and the historic character that should be presented to the public. It is accomplished through one or more construction projects, after which the structure is preserved by preservation maintenance. The categories of ultimate treatment are preservation, rehabilitation, restoration, and reconstruction.

Ultimate Treatment and Use (Historic Structure Report)
A narrative that discusses and analyzes the ultimate treatment and use of the structure as defined in park planning documents. If they have not been defined, this narrative may recommend an ultimate treatment and use. If analysis of the structure suggests that a planned treatment or use would adversely affect it, the text may present an alternative approach.

Unauthorized Commitment
An agreement that is not binding solely because the Government representative who made it lacked the authority to enter into that agreement on behalf of the Government. (FAR 1.602-3(a))

Undertaking
As referred to in Section 106 of the National Historic Preservation Act, an undertaking is any federal, federally assisted, federally licensed, or federally sanctioned project, activity, or program that can result in changes in the character or use of historic properties. Undertakings include new and continuing projects, programs, and activities that are:

  1. directly undertaken by federal agencies;
  2. supported in whole or in part, directly or indirectly, by federal agencies;
  3. carried out pursuant to a federal lease, permit, license, approval, or other form of permission; or
  4. proposed by a federal agency for congressional authorization or appropriation.

Undertakings may or may not be site-specific. (See 36 CFR 800.2[0] and section 301[7] of the National Historic Preservation Act.)

Uniform Federal Accessibility Standards (UFAS)
This document presents uniform standards for the design, construction and alteration of buildings so that persons with disabilities will have ready access to and use of them in accordance with the Architectural Barriers Act, 42 U.S.C. 4151-4157. The document embodies an agreement to minimize the differences between the standards previously used by four agencies (the General Services Administration, the departments of Housing and Urban Development and Defense, and the United States Postal Service) that are authorized to issue standards under the Architectural Barriers Act, and between those standards and the access standards recommended for facilities that are not federally funded or constructed.

This document sets standards for facility accessibility by persons with disabilities for Federal and federally-funded facilities. These standards are to be applied during the design, construction, and alteration of buildings and facilities to the extent required by the Architectural Barriers Act of 1968, as amended.

Unilateral Modification
A contract modification that is signed only by the Contracting Officer. Unilateral modifications are used, for example, to:

  1. Make administrative changes;
  2. Issue change orders;
  3. Make changes authorized by clauses other than a changes clause (e.g., Property clause, Options clause, Suspension of Work clause, etc.); and
  4. Issue termination notices. (FAR 43.103(b))

United States Department Of Transportation (USDOT) or (DOT)
The Federal cabinet-level agency responsible for highways, mass transit, aviation and ports; headed by the secretary of transportation. The DOT includes the Federal Highway Administration and the Federal Transit Administration, among others.

Universal Design Principles
The design of products, communications, and environments to be simple and usable by people of all ages, sizes and abilities (including disabilities) without the need for special adaptations or specialized design. There are 7 principles:

  1. Equitable use for any group of people
  2. Flexibility - choice; adaptability to user's needs and abilities
  3. Simple and intuitive to use in spite of users experience level, language skills, knowledge or concentration level
  4. Perceptible information is provided regardless of user's sensory abilities or ambient conditions
  5. Tolerance for error - minimal hazards and adverse consequences or accidental/unintended consequences
  6. Low physical efforts required - efficient and comfortable
  7. Adequate size and space for approach regardless of user's body size, posture or mobility
