3. ALL OVERHEAD CONTACT SYSTEM EQUIPMENT AND ASSEMBLIES SHALL

CLEAR ALL APPROPRIATE CLEARANCE ENVELOPES AND ELECTRICAL

ALL FIELD CONNECTIONS SHALL BE BOLTED UNLESS OTHERWISE NOTED.

BOLT HOLES SHALL BE SIZED TO CLEAR BOLTS WITH ALLOWANCE FOR

PURPOSE, BOLT DIAMETER, AND GALVANIZING THICKNESS.

AESTHETICS SHALL BE A MAJOR CONSIDERATION OF THE DESIGN IN

5.

UNLESS OTHERWISE NOTED, ALL MISCELLANEOUS STEEL BRACKETS,

FASTENERS AND FITTINGS SHALL BE DESIGNED AND MANUFACTURED,

STANDARD DRAWINGS INCLUDE TECHNICAL SHEETS, TYPICAL SPAN

DRAWINGS, TYPICAL STRUCTURE DRAWINGS, AND ASSEMBLY DRAWINGS.

TECHNICAL SHEET DRAWINGS PROVIDE BASIC AND DEVELOPED DATA

RELATING TO THE OVERHEAD CONTACT SYSTEM AND ITS RELATIONSHIP

WITH OTHER EQUIPMENT AND SYSTEMS.

GENERAL ARRANGEMENT DRAWINGS TYPICALLY DEFINE AND SHOW THE

REQUIRED RELATIONSHIP BETWEEN MULTIPLE SPANS OF WIRING AND

MULITPLE STRUCTURES.

RELATIONSHIP BETWEEN VARIOUS OCS ASSEMBLIES NEEDED TO FIT OUT

TYPICAL STRUCTURE DRAWINGS SHOW A CROSS SECTION VIEW OF

INDIVIDUAL STRUCTURE TYPES AND THE RELATIONSHIP BETWEEN VARIOUS

OCS ASSEMBLIES NEEDED TO FIT OUT THE STRUCTURE.

STANDARD ASSEMBLY DRAWINGS SHOW ONE OR MORE ASSEMBLIES OF

GENERIC PARTS WITH REQUIRED DIMENSIONS, INSTALLATION REQUIREMENTS,

AND A BILL OF MATERIALS TABLE. ASSEMBLIES ARE IDENTIFIED BY

DISCRETE REFERENCE NUMBERS.

THE DETAILING OF ASSEMBLIES SHALL BE THE RESPONSIBILITY OF THE

CONTRACTOR. UNLESS OTHERWISE NOTED, CONTRACTORS AND SUPPLIERS

ARE ENCOURAGED TO PROVIDE THEIR OWN STANDARD ASSEMBLIES AND

COMPONENTS PROVIDED THAT THEY MEET THE REQUIREMENTS FOR

PURPOSE, DIMENSIONAL PERFORMANCE AND SPECIFICATION. DETAILING

SHALL INCLUDE PARTS IDENTIFICATION AND BILL OF MATERIALS

LOAD STEADY ARMS ARRANGED TO SHARE LOAD EQUALLY.

HEAVY RADIAL LOADS OF UP TO 1000 POUNDS SHALL BE SERVICED BY USING TWO MEDIUM

500 POUNDS. THE STEADY ARM HEEL PIVOT POINT IS TO FALL WITHIN AREA "M" SHOWN.

MEDIUM LOAD STEADY ARMS ARE TO BE SUITABLE FOR RADIAL LOADS UP TO

POUNDS. THE STEADY ARM HEEL PIVOT POINT IS TO FALL WITHIN AREA "L" SHOWN.

LIGHT LOAD STEADY ARMS ARE TO BE SUITABLE FOR RADIAL LOADS UP TO 200
