About this file

This is the U.S. Army Information Systems Engineering Command (USAISEC) Drafting Guide, a technical standard document establishing uniform practices for preparing and drafting engineering drawings within the organization. The guide is based on the U.S. Army Corps of Engineers (USACE) Architectural, Engineering, and Construction (A/E/C) Computer Aided Design (CAD) Standard (STD), release 6.0, and the National CAD Standard (NCS), Version 6.

The document provides comprehensive guidance on basic drawing guidelines, including orientation standards, line work conventions, dimensioning formats using spaces instead of commas for five or more digits, and symbology requirements. It defines five basic drawing types used within USAISEC: Engineering Drawings (for design and installation), Redline Drawings (reflecting actual installation methods after completion), As-Built Drawings (showing actual installation results), Standard Drawings (reusable designs for various facilities), and Plant-in-Place Drawings (recording current facility configurations). The guide establishes detailed drawing file organization protocols, including model space and layout space usage, drawing number conventions, and a three-part file naming structure incorporating geographic location, facility type, drawing type, and revision control. USAISEC Common Drawing Designators are provided with twenty-six detailed drawing types ranging from Drawing Index (DI) and System Diagrams (SY) to Cable Running Lists (CL) and Miscellaneous Details (MS). The document specifies border sheet templates for three sheet formats, layer assignments for both model space and layout (paper space), and provides standard AutoCAD symbols and blocks. Additional appendices contain transmission system engineering drawing guidance, A/V and Visual Information System layer naming conventions, reference standards, border templates, and legacy Installation Information Infrastructure Modernization Program (I3MP) specific guidance including file naming conventions and standard three-letter site designations for military installations. The guide requires a waiver from the USAISEC Technical Director for any deviations from these standards.

DRAFTING GUIDE

1.0 INTRODUCTION

1.1 Background

The U.S. Army Information Systems Engineering Command (USAISEC) developed this drafting guide to provide a baseline for the development of engineering drawings within USAISEC. This guide was developed using material from the U.S. Army Corps of Engineers (USACE) and the National Computer Aided Design (CAD) Standard (STD) (NCS). The intent of the guide is to address drafting practices and processes unique to USAISEC with the Architectural, Engineering, and Construction (A/E/C) CAD STD as the Department of Defense (DoD) STD and the NCS as the foundation.

1.2 Scope

This guide provides basic instructions and recommendations for drafting of engineering drawings created by USAISEC employees and Contractors. The document includes general drafting guidelines for USAISEC. It is understood that this guide cannot address every situation, so if your project or program requires deviation from this guide, a waiver from the USAISEC Technical Director (TD) is required. A Waiver Request Form is available in the TD’s SharePoint Library.

2.0 BASIC DRAWING GUIDELINES

2.1 General Guidance

The USACE A/E/C CAD STD is the established standard for the DoD; this guide is meant to provide additional clarification or address USAISEC unique drafting practices. Many of the guidelines provided in the following pages are also provided on the Standard Drawing (STD)-MS-000A, which is shown in Appendix H of this guide. STD-MS-000A will be referenced throughout this guide. The electronic version of this drawing is available in the TD’s SharePoint library. Many other helpful documents including border templates, are available in this library.

Many engineers and technicians have AutoCAD on their computers and are producing project engineering drawings. This guide provides a recommended standardized format and scheme for engineering drawings produced for USAISEC. Use of this guide will save time for the draftsperson and will allow for standardization on drawings. Some long term programs have developed specific processes, which may continue to be used. Guidance for specific programs is identified in the appendices of this guide. Drawings can be provided to the draftsperson in any format to include hand sketches, Visio, PowerPoint, and AutoCAD/AutoCAD Lt. AutoCAD/AutoCAD Lt is the preferred method of submission.

All drawings will be returned from the draftsperson in AutoCAD.

2.2 Types of Drawings

There are five basic types of drawings commonly used within USAISEC. The five basic types of drawings are:

a. Engineering Drawing. Drawings developed for the design and installation of equipment and systems. These are drawings for specific projects that will be implemented in the future.

b. Redline Drawing. Drawings that have been redlined/updated to reflect the actual method or location of installation (after completion) of a specific project. These drawings are delivered to a draftsperson, so As-Built drawings can be developed. The drawings can be engineering drawings or standard drawings that have been redlined/updated.

c. As-Built. Drawings which reflect the actual method or location of installation (after completion) of a specific project. These drawings are usually the result of engineering drawings which have been annotated during installation to show changes necessitated by on-site conditions. The drawings are typically delivered to the customer as a finished product.

d. STD. STDs contain information that can be used (and reused) by design and installation personnel on various facilities and projects to design, specify, or install specific equipment or systems. These drawings are not specific to any particular site.

e. Plant-in-Place. Drawings used as a record of what was installed and how it was installed. Plant-in-Place drawings are drawings which reflect the current configuration of an operating communications facility. The Plant-in-Place drawings differ from as-built drawings since they cover the whole facility not just a particular installation or upgrade.

2.3 Orientation

a. Plans, elevations, and details. Views shall be oriented on the sheet, so that elevations and features are aligned whenever possible. When detailing is being added, details shall appear on the sheet based on their orientation on the feature. For instance, a detail of the top of a wall shall be orientated above a detail of the bottom of the wall. If a detail is taken from a large-scale plan or elevation, the orientation shall remain the same as the view from which the cut was taken. If this is not possible, a note stating that the orientation was changed will be added (i.e., VIEW ROTATED 90-DEGREES). When two or more plans of the same structure or the plans of two or more different structures are put on the same drawing, the orientation of all must conform to one another and to their relative positions on the ground.

b. Maps and drawings. Civil works maps and drawings shall be oriented, so that north is toward the top of the sheet when practicable, or toward the left of the sheet ,if top orientation is impracticable.

c. Vicinity maps. Vicinity maps will be oriented with north toward the top of the sheet.

2.4 Line Work

To be consistent with the USACE A/E/C CAD STD, Tables 3-1, 3-2, 3-3, and the NCS, Section 4.2.7, various types of lines require specific line weights.

2.5 Fractions and Commas/Spacing in Dimensions.

Scaling has to be exact to the actual dimensions. For metric units (per the A/E/C CAD STD) or inch-pound units, a space replaces the traditional comma in numbers containing five or more digits (see Figure 1). In numbers containing four digits, no space is necessary. Dimensions can be either inline or above the line, and must remain consistent for all drawings within a project.

Figure 1. Format for Dimensions

2.6 Symbology

The library of common symbols is listed in Appendix D of the USACE A/E/C CAD STD.

Project specific symbols are listed in the border sheet model files.

a. Symbol descriptions shall follow the following basic guidelines to allow their repetition from job to job, preclude conflicts within the drawings, and maximize suitability for CAD interface:

1. Symbol descriptions in legends shall be concise and worded in a comma-separated structure that flows from the general to the specific. For example, in lieu of wording the description of a convenience receptacle as “WALL-MOUNTED, DUPLEX RECEPTACLE,” structure the wording as “RECEPTACLE, DUPLEX, WALL-MOUNTED.”

2. The symbol description should not contain specific information that would normally be contained in equipment schedules or on the plans.

3. Where equipment or devices within a room are all identical, one symbol can be identified with the full type identifier and other information, and a callout can be referenced to this symbol with the following words: “Typical for this room.” Do not use the word “typical” by itself without additional wording to show where the typicality applies.

b. Symbol identifiers. Identifying letters within and around symbols must be legible at one-half normal size. Therefore, letter sizes within and around symbols shall be a minimum of 1/8-inch (3-millimeters (mm)) in height (unless the NCS specifically calls out a text height of 3/32-inch (2.5-mm) for that symbol (e.g., Detail Indicator)).

2.7 Redlining

The development of redlined drawings takes place during the installation using a standard method of denotation and process. Drawings that have been redlined/updated, reflect the actual method of installation (after completion). Although some USAISEC programs/projects have specific processes in place for redlining drawings within AutoCAD, the following general guidelines shall be used for denotation:

● Red will indicate changes

● Yellow highlight will indicate deletions

● Blue will indicate notes to the draftsperson

The redlined drawings will be used to develop the as-built drawings. The as-built drawings from the project are combined at the site/facility to the Plant-in-Place drawing repository. The Plant-in-Place drawings include all of the as-built drawings from all previous installations/upgrades at the site/facility.

2.8 Drawing Revisions

Drawing practices associated with drawing changes shall be consistent with those already used on the drawing to be revised, unless the latest of applicable standards can be incorporated without conflict. Any change to a drawing after release shall be recorded in the Revision History Block.

2.8.1 Revision Methods

Changes may be made by adding, deleting, crossing out the information, or by re-drawing the drawing.

2.8.2 Re-Drawn Drawings

Depending on the circumstances, a drawing may be redrawn either with or without change.

2.8.3 With Change (Revision Letter is Advanced)

When a revision warrants re-drawing of the drawing, the revision letter next in sequence shall be entered in the REV column of the Revision History Block of the new drawing.

See Figure 2.

2.8.4 Without Change (Advance of Revision Letter is not Required) When a drawing, or a sheet of a drawing is to be replaced because of loss, destruction, or degradation due to age, it may be re-drawn without change. The replacement shall duplicate the requirements of the old original, which is being replaced.

Figure 2. Example Revision Block

2.9 Superseding a Drawing with that of a Different Number

2.9.1 Superseding (New) Drawing

When a drawing is superseded by a drawing with a different number, the notation “REPLACES WITH CHANGE DRAWING (Enter superseded drawing number) REV

07OCT13

MINOR REVISIONS 07OCT13A

COMPUTER DRAWN, AUTOCAD 13

DESCRIPTION

REVISION

REVZONE DATE APPROVED

(Enter superseded revision letter, or if no revision, enter a – [dash])” shall be entered in the DESCRIPTION columns of the superseding drawing.

No entry is required in the REV letter, DATE, or APPROVED Columns. New Title Block Approval entries apply.

2.9.2 Superseding (Old) Drawing

When the superseded drawing will be retained, the notation “REPLACED WITH CHANGE BY DRAWING (Enter the superseding drawing number) REV (Enter the revision letter of the superseding drawing, or if no revision, enter a – (dash))” shall be entered in the DESCRIPTION column of the superseded drawing.

2.10 Revisions of Digital Data

Revisions of digital data files and copies of digital data files shall not be considered re-draws, except when the document is converted from a manually maintained to a digitally maintained document.

2.10.1 Revision Letters

● Upper case letters shall be used in sequence beginning with “A” and omitting letters “I”, “O”, “Q”, “S”, “X”, and “Z”.

● When the single letters have been exhausted, the revisions following “Y” shall be “AA” through “AY”.

● Should “AA” to “AY” be exhausted the next sequence shall be “BA” through “BY”.

● Revision letters shall not exceed two characters.

● Initial issue of a drawing does not constitute the need for a revision letter and may be indicated by the use of a - (dash).

2.10.2 Revision Locations

When incorporating a change or replacing the drawing, a revision location shall be identified using:

● Description in the Revision History Block

● Zone locations in the ZONE Column of the Revision History Block

2.10.3 Multiple Changes.

All changes authorized by a single revision request shall be incorporated into the document at the same time. All changes to a drawing incorporated at one time shall be identified by the same revision letter, if the revision letter is assigned at the time the changes are incorporated.

Sequence Number Use: When a revision involves two or more individual changes on a drawing, each change may be identified by a sequence number enclosed in parentheses preceding the description of the change.

2.11 Drawing Packages Organization and Index

Drawing packages shall be organized using the drawing index sequence shown in Table 1 and on Figure D-2 (STD-MS-000A, sheet 2) in Appendix D of this document.

2.11.1 Text in Drawings

2.11.2 General Notes

Notes on drawings shall be clear and concise. General Notes are notes with universal application to work on all drawings or to all work on specific drawings. General Notes shall be worded such that they are independent of the drawing(s), without cross-referencing or pointing with leader arrows to plans, details, etc. General Notes shall be capable of being removed from the drawings and placed in the specifications. The title above a group of General Notes applicable to sheets for a particular discipline (e.g., Architectural, Electrical, Mechanical, etc.) shall be worded “GENERAL NOTES:

APPLICABLE TO ALL (Insert Discipline) SHEETS.” General Notes applicable to specific sheets shall be worded “GENERAL NOTES: THIS SHEET ONLY” or “GENERAL NOTES:

SHEETS ______ THRU _______.” Notes shall not include contractual requirements, such as statements of costs; time and place of delivery; methods of payment; and requirements for submission, approval, or distribution of data or reports. All General Notes will be placed in the far right column of the drawing area of the Sheet File.

Wherever General Notes are used, they will be shown with a 1/4-inch (6-mm) title heading of “GENERAL NOTES.” All notes under the General Notes heading will be numbered sequentially starting with 1.

2.11.3 Subject Titles

When only one subject appears on a drawing, and its title appears in the title block, a subtitle should be shown under each view or detail on the drawing. When more than one subject appears on a drawing, a title should be shown under each subject, and a subtitle shown below each view or detail in that group.

2.11.4 Orientation

Text shall be set parallel to the primary base of the drawing. If necessary, text can be rotated at 30-degree angles up to 180-degrees, as long as the orientation is as shown in Figure 3. However, rotating the text is discouraged to prevent having to turn the drawing sheet to read notations.

Note: An exception to maintaining this text orientation would be on waterway projects because of the various directions in which channels are located. Often, text that has a definite bearing on the contract is kept at proper orientation, while map features incidental to the contract are allowed to follow the orientation when created in a north-up base map, which may result in upside-down text on rotated plan sheets.

Figure 3. Orientation of Text

2.11.5 Abbreviations

Abbreviations for words or phrases frequently used in plans, sections, elevations, or details should follow discipline-unique abbreviations. Abbreviations for words or phrases frequently used in plans, sections, elevations, or details should follow the abbreviations as established in the A/E/C CAD STD and NCS. A copy of the NCS abbreviations list is available in the TD’s SharePoint library. In addition, the following rules regarding abbreviations shall be followed:

● Abbreviations shall be used only when necessary and when their meanings are unquestionably clear. When in doubt, spell out.

● Once an abbreviation has been used, the same abbreviation must be continued throughout the project document.

● Only one abbreviation is allowed for each nomenclature.

● Any abbreviation used shall be identified in the abbreviations list of the drawing set.

3.0 DRAWING FILE ORGANIZATION

3.1 Model Space

All drawings will be done in model space. Model space drawings (model files) represent full-size drawings of building elements, systems, or information (e.g., the mechanical Heating, Ventilation, and Air Conditioning (HVAC) system, the architectural floor plan, details, or sections), and sheet files represent final plotted sheets. Model files are used as components in creating plotted sheet files. The information contained within a model file for a discipline may be referenced by other disciplines to create the particular model files or sheet files for that discipline.

a. Model-space-specific information represents the physical form of a site, a building, or other elements. This information is often shared between CAD files (both model space and paper space) through the use of external reference files. Examples include walls, doors, light fixtures, racking, cabinets, and equipment. Model-space-specific information may be either literal (e.g., walls) or symbolic (e.g., electrical outlets).

b. Layout-specific information may include notes, annotative symbols, and titles.

This type of information is usually not shared between CAD files or drawings. Design models inside a layout contain graphic information that would relate to real-world information (e.g., point coordinates), or information that would be sectioned off into multiple sheets (e.g., a floor plan that may take three sheets to present because of its size). Layout-specific information would include items specific for the presentation of that sheet. This is one reason that layouts should never be used as a reference file to other files.

3.2 Layout Space

Layouts are the final project sheets that are ready to be plotted. A layout contains specific information (e.g., north arrows, scales, section cuts, title block information) in a layout (Paper Space). A design model inside the layout contains the model space information assembled as it would be displayed in paper space. This model would have real-world spatial alignment, and would be used as the primary model for graphical information to be displayed and presented in the layout.

3.3 List of Materials (LOM)

The LOM required for the assembly of items in a drawing shall be listed, as shown on STD-MS-000A (see Appendix D). Note that abbreviations are allowed in the LOM (this is an exception to paragraph 2.11.5). The listing shall include the following:

a. Find Number. The column FIND NO. is a sequential number used to identify the items contained in the LOM. The number is used in conjunction with a circle and pointing arrow in the drawing, which identifies the items location. The number is used to cross-reference an item on the list with the location of the item in the drawing.

b. Description. This is a short description of the item.

c. Manufacturer. This is the manufacturer or source of the item.

d. Part Number. This is the manufacturer’s part number or National Stock Number (NSN) (if required) for the item.

e. Unit of Issue (UI). This is the UI of the material. An example would be Feet (FT) for a length of cable.

f. Quantity (QTY). This is the QTY required of the item for this particular assembly or on this particular drawing.

The condensed STD-MS-000A drawing shown in Figure 4, provides examples of both the lower right hand corner Title Block and the Title Block aligned vertically along the right side of the drawing. Either method is acceptable and must remain constant throughout all drawings on a project.

Figure 4. STD-MS-000A Title Block

3.4 Drawing Numbers and Electronic File Naming Conventions (USAISEC Modification from the USACE A/E/C STD) The naming conventions are the same for the drawing numbers and the electronic drawing files. The scheme described below allows CAD users to determine the contents of a drawing without actually displaying the file. It also provides a convenient and clear structure for organizing drawing files within project directories. The following is a recommended approach for naming drawing files.

The model file naming convention (Figure 5) is broken into three parts. The first part has four mandatory fields. A hyphen is used to separate the three parts. The second part has two mandatory fields. The third part has two fields and is used for revision control of the drawing. All fields must be filled out to correctly identify the location, type of facility, the drawing type, and the revision for the drawing.

Figure 5. Project Drawing File Naming Convention

Part one of the naming convention is as follows (See Figure 6):

● The first field is a one character field for the geographic location or theater of operation that the facility is physically located. Examples: E-Europe, C- Continental United States (CONUS), S-Southwest Asia (SWA), P-Pacific. Refer to Appendix B Table B-2 for a list of this information.

● The second field is a two character country or state in which the facility is physically located. Examples: GE-Germany, BE-Belgium, AZ-Arizona, KO- Korea. Refer to Appendix B Table B-3 for a list of this information.

● The third field is a three character field abbreviation for the name of the facility.

Examples: VIA-Patch Barracks, FTH-Fort Huachuca. Refer to Appendix B Table B-4.

● The fourth field is a two character field that identifies the type of facility.

Examples: TC-Technical Control Facility, TL-Telephone Switch, MW-Microwave.

Refer to Appendix B Table B-4 for a list of this information.

2 character code that identifies the type of facility

3 character code that identifies the post, camp, or station

2 character code that identifies the country or state

1 character code that identifies the geographic location or theater of operation

Figure 6. Part One of File Naming Convention

Part two of the naming convention is as follows (See Figure 7):

● The first field is a two character field to describe the type of drawing. Examples:

FP-Floor Plan, RE-Rack Elevation, RD-Cable Rack Diagram. Refer to Appendix E for a list of this information.

● The last field is a five position numeric designator. Use a numeric sequence beginning with 00001. Drawing numbers assigned to project drawings at USAISEC will have a “9” in the first position, i.e., 90001. Drawing numbers assigned to drawings prepared by USAISEC Contractors will have an “8” in the first position.

FP90001

2 character code that identifies the type of drawing

5 position numeric designator that is sequential starting with 00001. USAISEC drawings will start with “9” & USAISEC contractors will start with “8” in the first position

Figure 7. Part Two of File Naming Convention

Part three of the naming convention is as follows (See Figure 8):

● The first field is a three character field to describe the revision of drawing. This will always be REV.

● The last field is a two position character designator. Use a character sequence beginning with “A” for the first revision to an original drawing file.

● Upper case letters shall be used in sequence beginning with “A” and omitting letters “I”, “O”, “Q”, “S”, “X”, and “Z”.

● When the single letters have been exhausted, the revisions following “Y” shall be “AA” through “AY”.

● Should “AA” to “AY” be exhausted, the next sequence shall be “BA through “BY”.

● Revision letters shall not exceed two characters.

● Initial issue of a drawing does not constitute need for a revision letter and may be indicated by the use of a - (dash).

REV---

3 characters that will always be REV.

3.5 USAISEC Common Drawing Designators

The following list indicates the general order of drawings in a drawing package; however, not all drawings are necessary for each project. The drawing package starts with an index. The index should include columns for a drawing number, revision number, title, and remarks. The following descriptions provide information on the common USAISEC drawings.

a. Drawing Index “DI”. This is the first sheet or drawing in each set. This is a complete list of drawings for a project, site, or facility. The drawing index is usually prepared on an American National Standards Institute (ANSI) B-size sheet (see Table 2 for description of sizes) or on several sheets, and it lists all of the drawings in the set by drawing number and title. This index shows the number of sheets for each drawing if more than one sheet is used, and it displays the revision of each drawing. Usually, only one drawing index is prepared for a site or facility; however, when the site is part of several major communications systems, more than one may be required. If a particular drawing is applicable to more than one system because of positioning, interconnects, etc., it will be listed on each of the respective drawing indexes.

b. System Diagram “SY”. This drawing shows the interrelationships and connectivity of the component elements of a system. This diagram uses labeled circles or rectangles to represent system elements and uses lines to represent connections. This diagram also uses symbols to portray special characteristics of system components (i.e., repeaters, passive reflectors, interfaces with other systems, etc.).

c. Base Layout Drawing “BA”. This is a to-scale drawing that provides the base boundaries, including the placement of properties, roads, streets, railroads, waterways, runways, and survey markers, as well as the location of the different Communications- Electronics (C-E) facilities. This drawing inserts a vicinity map to illustrate the physical relationship of the installation to the surrounding area. In addition, the base layout drawing proportions the vicinity map to size with the to-scale drawing. The installation layout drawing may contain a grid overlay to serve as the key sheet for Outside Plant (OSP) drawings. The grid should divide the base into rectangles that are 1,600-feet high and 2,400-feet wide. If it is necessary to show the details of a congested area on subsequent OSP drawings, the grid should use a larger scale, such as 800-feet by 1,200-feet. Grid lines should not cut primary buildings or C-E facilities. If this is not possible, do not divide these salient features into more than two parts. Details of each grid section will be contained on large-scale OSP drawings.

d. Site Plan “SP”. This drawing shows the overall site plan of the C-E facility and displays a plan view of the installation, to include the location and dimensions of major components and the location of survey markers, antennas, and antenna azimuths. A site plan may show manholes, ducts, underground and buried cables, aerial cables, and other OSP facilities, when not provided on base grid or cable diagram drawings.

e. Architectural and Engineering Drawing “AE”. These drawings show the design and engineering required for the manufacture of specific items, such as structures, buildings, open areas, or equipment. Architectural engineering drawings encompass construction requirements, manufacturing specifications, material requirements, style, character, and aesthetic values. The information is definitive, precise, and to-scale. The USACE can often provide this information for new buildings.

f. Building Layout Drawing “BL”. This is the key drawing for the family of drawings pertaining to a specific building. A building layout drawing is required for each building containing C-E facilities or portions thereof. This drawing must identify the room number and/or operational use of each room or area. The drawing notes state the type of building construction, floor composition, walls, and ceiling, as well as the floor capacity, ceiling heights, area floor space, and miscellaneous information. The plan view for this drawing is normally a single-line building outline showing all interior walls and partitions, and the plan view may show power ducts. The building layout drawing should be a to-scale drawing using as many sheets and match lines as necessary. Usually, this drawing requires one sheet for each floor. In this drawing, single lines represent inside walls, and breaks in the lines represent internal and external access openings of the building.

Furthermore, symbols indicate electric, power, water, heat, and ventilation service entrances or internal source locations in a building layout drawing. This drawing identifies the major C-E facility and equipment locations, the supporting floor plans, and the location of the building as shown on the base layout map.

g. Cable Vault Drawing “CV”. This drawing shows the location, layout, racking, cabling, splicing, steps, access ports, and ceiling sleeves in a cable vault. This drawing also shows the relationship of the vault to the building and an elevation view showing length, width, headroom, and duct arrangement. In addition, a cable vault drawing shows the arrangement of cables on racks and the approximate location of valves, pressure plugs, sleeves, and splices, as well how the cables enter the vertical side of the Main Distribution Frame (MDF). This drawing must identify the cable or trunk number, cable count, and number of pairs. Prepare only one cable vault drawing per building with C-E functions.

h. Floor Plan “FP”. Use this drawing to support a building layout drawing. A floor plan provides detailed information about specific communication rooms. A floor plan is drawn with the maximum space available at the top of the sheet to leave room for an equipment legend and description. The drawing title must contain the numerical identification of the building, room number, and area, as well as the base and/or site name and address. A floor plan must contain a plan view of a room or area as identified by the building layout drawing. A floor plan also must show wall thicknesses, door swing directions, and access openings, as well as the location of all partitions, columns, and dimensions, to establish special limits in all directions. A floor plan identifies interior dimensions, numerical designations, and/or operational uses of all rooms or areas. Note any element of restriction to the installation, maintenance, or operation of C-E equipment on this drawing. Identify all C-E equipment installed or programmed onsite, and ensure the equipment is shown to scale and identified in the drawing legend. Heavier lines should indicate equipment fronts in a floor plan.

i. Rack Elevation Drawing “RE”. This is a dimensional, elevation view of equipment racks, consoles, and cabinets showing the equipment arrangement and blank panels. In this drawing, the item number must identify equipment when an equipment legend is used. A rack elevation drawing must show the shapes and sizes of compartments, assignments of space, and general mechanical and electrical details of component mounting. Note the building, room, equipment row, and operational use of the equipment on this drawing. Prepare one rack elevation drawing for each facility.

j. Wall Elevation Drawing “WE”. This drawing depicts all equipment. This includes furniture and accessories mounted on transportable van and shelter walls or on building walls.

k. Distribution Frame (DF) Drawing “DF”. This drawing shows the placement, layout, arrangement, and numbering of each MDF, Intermediate Distribution Frame (IDF), and Combined Distribution Frame (CDF). This drawing must identify the terminal blocks and cable run numbers of all cable runs to the frame, as well as terminal block designations. This drawing also includes the location and identification of protectors and terminal strips on a frame, whether these are in use or reserved for future use. This type of drawing should indicate set jacks and detail views presented when those terminal strips serve more than one circuit. Only one set of DF drawings is normally prepared for each building. Each sheet of the drawing will show only one DF.

l. Terminal Block Layout and Assignment Drawing “TB”. The installers and maintenance personnel use these drawings to identify each terminal block in a DF (MDF, IDF, CDF, etc.), each terminal block’s function, and where the other end of the cables terminate or originate. This data will include pictorial views of the blocks and frame, identification of the blocks, and pertinent information in narrative or tabular form. This drawing’s data will be used in conjunction with the Cable Running List (CRL). The terminal block layout and assignment drawing should identify all spare blocks, terminals, wires, and cables.

m. Cable Rack Diagram “RD”. This drawing shows the construction and placement of cable racks, runways, raceways, trays, ducts, etc., used to support the interfacing cables. This diagram will use a plan view that shows the cable rack relative to equipment and building features. This diagram will also use an elevation view to supplement the plan view by using heavy lines to indicate the rack and light lines to indicate the equipment. A cable rack diagram should identify the type and size of components in the drawing (i.e., conduits, elbows, dropouts, and reducers), if engineering requirements demand such information.

n. Grounding System Drawing “GS”. These drawings show all the details necessary to depict all grounding systems associated with the facility, both inside and outside the building. Schematically, these drawings also show how and where cable shields, equipment cabinets, individual equipment, and other devices are grounded and bonded.

Grounding system drawings show the entire communication facility’s grounding system, including onsite power distribution, protective ground, lightning protective ground, signal ground, special Electromagnetic Pulse (EMP) protective ground, and an Earth Electrode Subsystem (EES). In addition, these drawings show all specialized hardware and techniques used to provide grounding, such as the use of chemicals, counterpoises, ground rods, wells, etc. Grounding system drawings should also display the EES’s resistance-to-earth measurements and the methods of measurement, including the date of the last measurement.

o. Power Diagram “PD”. These drawings are specific in nature to identify power and the corresponding circuits. These diagrams are one-line diagrams that describe the Alternating Current (AC) and Direct Current (DC) power systems, emergency and standby power, and safety/utility grounds (but not signal grounds), including special grounds installed for lightning and EMP protection. Power diagrams show all circuits, breakers, conduits, and other related hardware available for use in the power system. These diagrams also show power distribution to the equipment and cabinet(s), including the circuit assignments and power capacities of all outlets. In addition, power diagrams show unique features, such as Uninterruptible Power Supply (UPS) systems, automatic switchover systems, and monitor and control circuits. These diagrams should clearly identify any provisions required to expand the power system. Furthermore, power diagrams should include any tabular and narrative data necessary to describe the entire power system clearly.

p. Unistrut Plan “UP”. This drawing will provide a plan view of the unistrut installed in the technical equipment area. A unistrut plan is a superimposed drawing on the technical area rack layout. This plan provides a detailed view depicting the unistrut cross-section and model number (i.e., P-1000).

q. Installation Drawing “IN”. These drawings show how to mount, install, or place individual equipment at the facility. In addition, installation drawings provide details concerning the specific locations and actual securing of items. These drawings also provide supplemental information that is not available in the standard installation practice documents/drawings or manufacturer’s documents.

r. Interconnect Diagram “ID”. This block diagram shows the electrical connections of a system, as well as its components, parts, and devices. This diagram also shows the actual interconnection of equipment when it differs from the functional interconnection shown on the block and level diagrams. This detailed drawing will assist in the development of the CRL. The more accurate and detailed the information is on an interconnect diagram, the easier it will be to develop the CRL. An interconnect diagram helps to ensure the CRL is not missing any cables or interconnections between equipment.

s. CRL “CL”. These lists assist in identifying, in tabular form, the origin and termination of all cables used in the facility (i.e., signal, power, protective ground, signal ground, radio frequency cables and waveguides, control, and intercom). Symbols and narrative data supplement CRLs when necessary. The information shown in this list includes cable types, cable and wire sizes, cable functions, circuit assignments, identification coding, unused and spare wires and cables, and any special characteristics of the cables and wires. Use CRLs in conjunction with interconnect diagrams. The CRL will refer to standards and/or installation details that will tell the installer where to find a diagram for the cable assembly. This reference will include the drawing number, sheet number, and/or detail and table as required.

t. Circuit and Channel Assignment Drawing “CA”. This tabular drawing designates circuits and/or channel assignments to communications equipment that process more than one channel (i.e., patch panels, consoles controlling several radios, etc.). A diagram of the face of the equipment may assist in telling the installer what information to place on the label and where to place that label on the equipment being installed.

u. Cross-connect Diagram “XC”. This drawing depicts all permanent and semi-permanent wiring cross-connections between equipment on the distribution frame. This diagram includes the identification and location of equipment racks that interconnect.

v. Miscellaneous Detail Drawing “MS”. Use this drawing when requiring specific information that cannot be categorized in the detail codes of any other drawing listed in this document.

w. STD Drawing “SD”. This is a common and repeatedly used drawing showing the preferred configurations of installation items. This drawing contains information used by installation personnel to install specific equipment or systems.

x. Audiovisual (A/V) Drawing “TA”. Use this drawing for details specific to A/V equipment and systems.

y. OSP Drawing “OP”. This drawing shows the OSP, including buried cable, underground conduit, terminals, poles, and other features similar to OSP facilities. These features include cable numbers, number of pairs, pair counts, and terminal counts.

Usually, this drawing is keyed to the grid system established by the base layout.

z. Maintenance Hole (MH) Detail Drawing “MH”. This drawing shows the information required to install underground cables in a specific manhole. This drawing should provide a description of the manhole, to include the number and dimensions, location of entry points, cable racks, and type of drainage. In addition, this drawing should contain the number, type, material, and inside diameter of conduits; the arrangements of cable; and the location of coil cases and other pertinent equipment for manhole use.

5.0 LAYER ASSIGNMENTS

CAD layers serve to separate graphic elements (lines, shapes, and text) according to the design discipline they represent. Table 3 shows the typical model layers that will be used in USAISEC telecommunications projects. Table 4 shows the layers that will be used in the Layout Space layers. A complete listing of layers is identified in the NCS Version 6.

5.1 Model Space Layers

Model files represent full-size drawings of building elements, systems, or information (e.g., the mechanical HVAC system, the architectural floor plan, telecommunication systems, details, or sections), and sheet files represent final plotted sheets. Drawings in Model Space contain information in various layers. This provides structure to the AutoCAD file and simplifies the exchange of information. A recommended layering scheme for telecommunication systems is shown in Table 3. This scheme follows the NCS layer guidelines for naming layers with a discipline, a major group, up to optional minor groups, and an optional status field to clearly identify each layer. An exhaustive listing of standard layer naming details is available in the NCS Appendix A, which is located in the TD’s SharePoint Library.
