IEEE 951-1996 (R2009) pdf free.IEEE Guide to the Assembly and Erection of Metal Transmission Structures.
This guide presents various good practices that will enable users to improve their ability to assemble and erect sell-supporting and guyed steel or aluminum lattice and tubular steel structures. It also covers construction considerations after Ibundation installation (see IEEE Std 977-1991 I), and up to the conductor stringing operation (see IEEE Sid 524-1992).
1.2 Purpose
The purpose of this document is to assist the parties involved with the installation of steel transmission structures. This document focuses on the design and construction considerations for material delivery, assembly and erection of metal transmission structures, and the installation of insulators and hardware.
1.3 Application
This guide is intended to be used as a reference source for parties involved in the ownership, design. and construction of transmission structures. Since methods will be strongly influenced by the nature of each project, various methods that have been successfully employed are presented.
If any of the recommendations contained within this guide are to he adopted. they should be specifically stated in the owner’s design and construction specifications. Any legal and environmental requirements of national, state, provincial, or local regulations shall be observed.
1.4 Safety
Handling. assembly, and erection of metal structures may require conducting a safety and health program that takes all reasonable precautions to protect the safety and health of workers and members of the public. Workers should not be alloed to work in surroundings or under working conditions that are unsanitary, hazardous, or dangerous to their health or safety. Any safety requirements of national, state, provincial, or local regulations shall be observed (see 111512).

This clause contains key terms as they are used in this guide.
3.1 constructor: A party who undertakes the assembly arid erection o a transmission struciure. Inc constructor can be an owner or an agent acting for an owner. Synonyms: contractor, installer, construction agency. construction department.
3.2 line designer: A party who develops structure loading criteria, structure types. and structure locations based on line routing, maintenance, and construction requirements. The line designer establishes design criteria for construction and maintenance that will affect the structure designer and constructor. The line designer could be an owner or an agent acting for the owner.IEEE 951 pdf download.
