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

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

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
