The existence of an IEEE Standard does not implythat there are no other ways to produce, test, measure, purchase, market, or provide other goods andservices related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed at thetime a stan

Every IEEE Standard is sub-jected to review at least every five years for revision or reaffirmation. When a document is morethan five years old

12、f standards asthey relate to specific applications. When the need for interpretations is brought to the attention ofIEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards rep-resent a consensus of all concerned interests, it is important to ensure that any in

Overview1.1 ScopeThis guide presents various good practices that will enable users to improve their ability to assemble anderect self-supporting and guyed steel or aluminum lattice and tubular steel structures. It also covers construc-tion considerations after
33、foundation installation (see IEEE Std 977-19911), and up to the conductor stringingoperation (see IEEE Std 524-1992).1.2 PurposeThe purpose of this document is to assist the parties involved with the installation of steel transmission struc-tures. This document focuses on the design and construction
34、 considerations for material delivery, assemblyand erection of metal transmission structures, and the installation of insulators and hardware.1.3 ApplicationThis guide is intended to be used as a reference source for parties involved in the ownership, design, andconstruction of transmission structur
35、es. Since methods will be strongly influenced by the nature of eachproject, various methods that have been successfully employed are presented.If any of the recommendations contained within this guide are to be adopted, they should be specificallystated in the owners design and construction specific

42、hey are used in this guide.3.1 constructor: A party who undertakes the assembly and erection of a transmission structure. The con-structor can be an owner or an agent acting for an owner. Synonyms: contractor, installer, constructionagency, construction department.3.2 line designer: A party who deve

The line designer establishes design cri-teria for construction and maintenance that will affect the structure designer and constructor. The linedesigner could

47、ct with the constructor for performing work covered by theContract Documents, when the constructor is not the owner.4. Project planning The line designer should consider all aspects of the project before proceeding with design. This includes areview of all available options for construction techniqu
48、es and equipment with respect to the specific condi-tions of the proposed line route. Access conditions, environmental restrictions, and/or schedule constraintsmay dictate the need to consider alternative, nontraditional construction techniques. If these requirementsare understood early in the proje
49、ct, the selection, design, and detailing of structures and foundations can betailored to accommodate these construction techniques. This early planning can result in a more cost-effec-tive project.The following factors can influence the selection of construction methods and equipment and should be con-sidered in the early planning of a transmission line:a) Line route and right-of-way conditionsb) Environmental constraints and public concernsc) Accessibility of structure sitesd) Configurations, sizes, and weights of structure
