3. DRAWING REQUIREMENTS.

3.1. Drawing Production.

3.1.1. Drawing File Format.

a. Vector drawings must be created in native MicroStation or AutoCAD file formats (DGN or DWG). Use of Drawing Exchange Format (DXF) should be avoided. Electronic drawing deliverables from contractors must comply with Section 4.0, Electronic Deliverables, of this standard. The preferred delivered drawing file format must be coordinated with the local CADD Manager.

b. Raster file format drawings must be generated in PDF Format and Tagged Image File Format (TIFF) Group 4.

c. CADD practices to avoid: custom fonts, custom patterns, custom line types or styles (other than those depicted in Figure 3-11 and Figure 3-12), nested blocks, nested “Xrefs” or nested reference files and infinite lines.

3.1.2. Creation of CADD Files

All models in a CAD file should be created at full-scale (1-to-1). Drawing borders and text-heights must always be scaled to fit the full-scale drawing model(s). Sheet/Paper models should be “plotted size” (12” = 1’-0”) and reference models scaled down to fit. For those instances where the model and sheet references are in a single, full-scale design model, refer to Table 3-1, Scale Factor and Text Height Conversion Table for standard engineering, architectural and mapping scale factors and text heights to be used with full-size drawing models.

3.1.2.1. Drawing Sheet Format

FAA-approved drawing sheet formats include common drawing features such as boundary geometry, title block data, filename, pathname, zoning guides, and title block geometry.

Copies of the approved sheet formats will be provided by the CAEG Program Office (PO) to both FAA and support organizations. All FAA offices and support organizations are required to use these formats. Contact the regional CAEG Administrators, who can provide FAA-STD-002 Standard drawing borders and logos used in creation of engineering drawings for the FAA. The FAA border, including the title block, for the sheet file can be ‘referenced’ into a drawing file as a seed file (DGN) or a reference block (DWG).

3.1.2.2. Drawing Sheet Sizes

The most commonly used FAA standard drawing sheet size is ANSI-D (22" X 34"). Other sheet sizes are allowed as needed, and construction drawings for any of the larger facilities (such as an ATCT and administrative building, or a TRACON) may utilize the E-size sheet.

All drawings within a set should be plotted on the same sheet-size if possible. Drawing sheet sizes and margins must follow the specifications shown in Table 3-2, Standard Drawing Sheet Sizes. Apply ASME Y14.1 Drawing Sheet Size and Format for any information not provided in this standard, but required on drawing sheet, such as border zoning specifications. The zoning specifications for the FAA D-size sheet are unique in that, the vertical margins contain eight zones (each measuring 2.75 in.) and the horizontal margins have eight zones (measuring 4.25 in. each). All zones should be measured from the edge of the sheet, and be aligned with the zones in the opposing margin.

Figure 3-1, Drawing Appearance

3.1.3. Drawing Border and Title Block

3.1.3.1. Border

The border is the rectangular frame surrounding the drawing. It contains a “zoning system” that can be used to call-out specific areas of a drawing when changes, or new graphics, are incorporated. The alphabetic characters are located on the left and right sides and the numeric characters are on the top and bottom. The zones are referred to using an alphanumeric description, such as “Zone F6” depicted in Figure 3-2, Drawing Zoning System.

Figure 3-2, Drawing Zoning System

3.1.3.2. Title Block

The title block shown in Figure 3-3, Drawing Title Block, is used for recording specific drawing metadata. The title block is located in the lower-right corner and just inside the drawing zone boundary. It is sub-divided into rectangular areas that contain specific text data such as drawing title, drawn by, approved by, date and drawing number. All text in the title block must be in upper-case, except for the electronic signatures, which may be both upper and lower-case characters.

3.1.3.2.a.

The title block in Figure 3-3 is subdivided into three main sections. The revision section is located at the top. The authorizing agency section is located in the middle and the main section at the bottom. The main section of the title block contains the title, signatures, drawing identification and the issuing office. All title blocks for drawing sizes D through F must conform to Figure 3-3. The title block overall dimensions are 7-3/8” x 5-5/16”.

3.1.3.2.b.

Items labeled in Figure 3-3 are described in Table 3-4, Drawing Title Block Descriptions.

The contractor logo must be located to the left of the title block and shall not exceed 2-1/4” in width. Any Professional Engineering seal should be located to the left of the Contractor identification block (or to the left of the title block, if the Contractor block is absent) and must not exceed 2-1/4” in width. The Configuration Management stamp, if needed, is to be located to the left of any graphic scales, space permitting, as shown in Figure 3-1, Drawing Title Block.

3.1.3.2.c.

Every drawing that is designated as For Official Use Only (FOUO) must also include the text “For Official Use Only” and “Public availability to be determined under 5 USC 552” as specified in FAA Order 1600.75, Appendix D. When required, the FOUO text must be placed centered above the drawing title block (see item 28 in Figure 3-3 Drawing Title Block).

3.1.3.2.d.

When a set of drawings has been designated as “Sensitive Security Information (SSI)”, each drawing must include the text as specified in FAA Order 1600.75 Appendix E, Marking Sensitive Security Information. This text will be placed centered above the title block.

Figure 3-3, Drawing Title Block

3.1.4.1.a. Location Identifiers.

The location identifier is assigned to each airport and the FAA facility is listed in the FAA JO7350.6 Location Identifiers or Facilities, Services Equipment Profile (FSEP) publications.

If a facility has multiple location identifiers associated with different runways, the airport identifier must be used in all cases.

3.1.4.1.b.

The drawing sheet size is indicated with an upper-case letter (i.e. D, E or F).

3.1.4.1.c.

Facilities may be co-located with another facility. More than one facility may be tied to a single Location ID. Facilities may be related to a runway. Each of the following examples addresses these unique situations:

a. Facilities co-located with another facility will be assigned the major facility’s facility-type. An example would be a DME co-located with a GS would use the GS as the FAC-type.

b. Multiple facilities with the same location identifier must have a letter appended after the facility-type. An example would be SLC-D-RTRA-XXXX, SLC-D-RTRB-XXXX.

c. Facilities related to runways may append the runway number to the facility type. An example would be SLC-D-GS13L-XXXX.

3.1.4.1.d.

NAS Equipment Drawing numbers for an ARTCC facility should be numbered with the equipment acronym used in place of the facility-type. An example, a DMN drawing at the Seattle ARTCC would be ZSE-D-DMN-Q001.

3.1.4.1.e. Drawing Sequence Numbers The Drawing Sequence Number for a construction drawing starts with an upper-case letter specifying the discipline, followed by a three-digit sequential number. An example of a construction drawing number is ORD-D-ATCT-A001. The discipline designators are listed below:

A-architectural G-general Q-NAS equipment Z-contractor / shop drawing C-civil H-hazardous material R-real estate/lease

D-demolition L-landscape S-structural E-electrical M-mechanical T-telecommunications F-fire protection P-plumbing Y-security

NOTE: High-voltage power connections will be shown on the Electrical Discipline (E- Electrical) drawings and low-voltage power connections will be shown on NAS Equipment (Q-NAS Equipment) drawings.

3.1.4.1.f.

Any Real Estate drawings will require the use of the Real Estate discipline designation within the drawing number. Real Estate drawings will utilize levels according to the Civil Discipline in Appendix A of this Standard. An example of a Real Estate drawing number would be ATL-D-RCAG-R001.

3.1.4.1.g.

The drawing number for a Configuration Management baseline drawing must insert a “-BL” at the end of the drawing number after the Drawing Sequence Number. The drawing number for a Configuration Management end-state drawing must insert an “-ES” in this same location. An example of a CM baseline drawing number would be ORD-D-TRACO-

A001-BL.

3.1.4.1.h.

Regional / National Standards must reference the two-letter regional code plus the letters “SD” representing “standard” in place of the Location Identifier. An example of a national standard drawing number would be WASD-D-ATCT-C001. The regional codes are as follows:

AL – Alaska CE – Central CT – Technical Center EA – Eastern GL – Great Lakes NE – New England

MC – Monroney Center NM – Northwest Mountain SO – Southern SW – Southwest WA – Washington, DC WP – Western Pacific

3.1.4.1.i.

Refer to the Facility, Service, and Equipment Profile (FSEP) website at https://employees.faa.gov/org/linebusiness/ato/operations/technical_operations/ajw1/ajw1B/fsep/ to obtain facility information for the creation of a drawing number. This website contains all of the authorized facility-types and equipment-types used within the FAA. Drawing numbers are to be assigned using facility-type acronyms, not equipment-type acronyms. For example: Terminal Voice Switch (TVS) is a valid equipment-type entry in the FSEP. Small Tower Voice Switch (STVS) and Enhanced Terminal voice Switch (ETVS) are types of TVS equipment. However, since TVS is not a facility acronym, the associated drawing numbers would be assigned the appropriate facility-type acronym (ATCT or TRACON).

Subsets of the FSEP listing can be used at the regional level; however the information used must be taken from the FSEP listing. Additional facility or equipment-types can be requested for inclusion into the FSEP by obtaining and filling-out an electronic form from the CAEG Program Office. The CAEG PO will act as a clearing point for the FSEP office to avoid duplicate requests. Two additional facility-types not listed in the FSEP will be allowed:

a. ALD – Airport Layout Drawing b. LAAS – Local Area Augmentation System

3.1.5. Non-NAS Facilities

Non-NAS facility drawings will use a slightly different number configuration, as shown in Figure 3-4B, Drawing Number Structure for Non-NAS Facilities. Any drawings created for these facilities must use the format LID-Project Number-Drawing Sequence Number. An example of a drawing number for the Technical Center at Atlantic City would be ACT- 1234567890-A001 for an architectural drawing.

Figure 3-4B, Drawing Number Structure for Non-NAS Facilities

3.1.6. Arrangement of Drawings

3.1.6.1. Construction Drawing Sets

The drawings in a construction drawing set are listed by discipline in Table 3-5, Construction Drawing Set. These drawings are commonly used in identifying a complete set of drawings for the construction of a new facility. Drawing sets for the construction of a facility modification must consist of a subset of the drawings listed in this table.

Construction drawing sets must be arranged by discipline in the following order:

3.1.6.2. Installation Drawing Sets

NAS electronic equipment drawings provide technical details for installation and maintenance of NAS mission equipment in facilities. All these drawings must have the "Q" designator with three sequential numerals for the drawing numbers, for example, Q001, Q002, Q003, etc. For arrangement and numbering of Q-series drawings at ATCT and TRACON facilities, refer to Table 3-6, ATCT/TRACON NAS Equipment Drawing Number List. All NAS facility equipment drawing sets at ATCT and TRACON facilities should include index sheets(s) documenting the drawing number sequence, and should reserve Q001 and Q002 for these index sheets. Each electronic system should include a System Functional (Block) Diagram as the first drawing in each drawing group. For all other facilities (except ARTCC facilities, see Section 3.1.4.1.d), the NAS electronic equipment Q-series drawings should be numbered in the following order starting with Q001: Electronic Equipment Floor Plan, Rack Elevations, Antenna Layout and Details, System Wiring Diagrams, Connection Block Assignments and others, as needed.

3.1.7. Typical Sheets and Layouts for Construction Drawing Sets Nearly all construction drawing sets will use one of the following six standard sheets and layouts described in the following six sub-sections. All of the drawings depicted in this section are D-size sheets.

3.1.7.1. Cover Sheet

Each construction drawing set must have a cover sheet that clearly identifies the drawing set. The cover sheet must have a title block containing the requisite information about the drawing set. See Figure 3-5, Cover Sheet Layout. If the Cover Sheet is part of a set of drawings that will be delivered outside of the FAA, the drawings may be required to include sensitive drawing marking information (as specified in FAA Order 1600.75 Appendix D, Marking FOUO Information), which will be placed centered above the title block. In addition a back sheet must be included with text as specified in FAA Order 1600.75.

Figure 3-5, Cover Sheet Layout

3.1.7.2. DOT/FAA Logo

The CAEG Program Office will provide the following electronically formatted logos to be included in CADD products: Department of Transportation (DOT), Configuration Management (CM) and Federal Aviation Administration (FAA).

3.1.7.3. Drawing Index Sheet

The second sheet of each drawing set should be the Drawing Index Sheet. This lists every drawing contained in the drawing set. An example is shown in Figure 3-6, Drawing Index Sheet.

NOTE: If a project consists of 15 drawings or less, the drawing index may be placed (centered) on the Cover Sheet below the Drawing Set Title.

Figure 3-6, Drawing Index Sheet

3.1.7.4. Floor Plan Layout

The Floor Plan Layout sheet is intended for all plan-type drawings regardless of discipline.

See Figure 3-7, Floor Plan Layout.

Figure 3-7, Floor Plan Layout

3.1.7.5. Elevation and Section Plan Drawing Layout

The elevations details must be stacked in the upper-half of the drawing field. The bottom of the drawing field is available for details when the detail sheet is full.

See Figure 3-8, Elevation and Section Plan Drawing Layout.

Figure 3-8, Elevation and Section Plan Drawing Layout

3.1.7.6. Detail Sheet Layout

A Detail Sheet Layout is a collection of details that clarify construction or installation details that cannot be shown at a smaller scale. The detail will cross-reference the detail with the drawing sheet from which it was taken. The typical layout has six columns, including an area for Notes and four rows. When the scale calls for a larger detail block, use surrounding blocks. Try to keep the details in square shaped blocks. Identify the blocks as shown in Figure 3-9, Detail Sheet Layout.

3.1.7.6.a.

Details should start with the first detail in the upper left-hand corner and move across the top of the sheet. Continue to create rows for new details below the first row of details. The area for Notes must be on the right-hand side of the sheet.

3.1.7.6.b.

Detail sheets with multiple scales should be scaled according to the primary detail on the sheet or, if there is no primary detail, according to the scale that represents the majority of the details. The remaining details should be referenced into the drawing at the correct scale.

Figure 3-9, Detail Sheet Layout

3.1.7.7. Schedule/Diagram Sheet Layout

Figure 3-10, Schedule/Diagram Sheet Layout, shows the format for schedules and diagrams that are frequently used in drawing sets for electrical, plumbing, and mechanical drawings.

The drawing field may extend above the title block, as long as the notes or legends can be relocated on the sheet as shown.

Figure 3-10, Schedule/Diagram Sheet Layout

3.1.8. Layers/Levels

CADD levels (MicroStation)/layers (AutoCAD) are analogous to overlays in manual drafting systems and serve to separate graphic elements according to the design discipline they represent. MicroStation and AutoCAD allow an unlimited number of levels/layers to be identified with names. The levels/layers defined within this standard are based on those set forth in the American Institute of Architects' publication, “CAD Layer Guidelines.” The AIA “Group” categories were used to develop the Level/Layer Naming Scheme found in Appendix A of this standard. The Real Estate Discipline (R-Real Estate) will not contain any levels/layers designations in Appendix A. Any levels/layers required to define any Real Estate features within a drawing can be found under the Civil Discipline levels/layers scheme located in Appendix A of this standard.

3.1.9. Text Styles/Fonts

Customized text fonts must not be used in FAA drawings. The True Type fonts are acceptable, if not desirable. Since there is not a direct relationship between MicroStation resource files and AutoCAD shape files, it is important that font use be reviewed at the start of a project and decisions made on fonts that are then used consistently throughout the project by the various disciplines. If a project is to be exchanged between CAD platforms, either because individual offices require different applications (or because the end-users require a specific software format) a general guideline is to use True Type fonts. These fonts will allow direct transitions between the applications, and are specified in Table 3-7, Comparison of Font Types. When True Type fonts are not utilized such as in older drawing files, use the fonts that are most compatible (nearly identical in appearance and size) between MicroStation and AutoCAD which are also defined in Table 3-7, Comparison of Font Types. These particular fonts do not translate perfectly and some cleanup may be required after any translation between systems.

FONT TYPE TrueType AutoCAD FONT MicroStation

FONT

Proportional Arial RomanS Working Monotext Lucinda Console Monotxt Engineering Standard Tahoma Txt Standard Roman Triplex Times New Roman RomanT Fancy

Slanted Arial (slanted angle21.8) RomanS (obliquing angle 21.8) Italics

Symbology Symbol GreekS Greek

Filled Arial Black Swiss 721 BT Low_Res_Filled

Table 3-7, Comparison of Font Types

a. Proportional – appropriate for general notes or labels. This font creates text where the characters are proportionally spaced. In AutoCAD, use the “RomanS” font with a width factor of 1.0. In MicroStation use Font #1, “Working” font. Also appropriate for subtitles.

b. Monotext – appropriate when text fields need particular justifications such as in schedules or title blocks. This font creates text characters that are evenly spaced. In AutoCAD, use the “Monotxt” font, and in MicroStation, use Font #3, “Engineering” font.

c. Standard – appropriate for notes, callouts, etc. In AutoCAD, use the “Txt” font. In

MicroStation use Font #0, “Standard” font.

d. Roman Triplex – appropriate for subtitles. In AutoCAD, use the “RomanT” font. In

MicroStation use Font #2, “Fancy” font.

e. Slanted – appropriate where certain text needs to be distinguished from other text, such as bodies of water. This font can be created in AutoCAD by using the “RomanS” font with the Obliquing Angle set to 21.8 degrees to achieve the American Standard slope of 2:5 (68.2 degrees). In MicroStation use Font #23, “Italics” font.

f. Symbology – This font provides special characters for use in labeling electronic components. In AutoCAD use the “GreekS” font with a width factor of 1.0. In MicroStation use Font #26, “Greek” font.

g. Filled – The filled font is used primarily for titles and on cover sheets. In AutoCAD use the Swiss 721 BT font. In MicroStation use Font #43, “Low_Res_Filled”.

3.1.9.1. General Text Placement

All drawing text shall be in upper case, except for special case abbreviations such as “dB”, “MHz”, and “NiCd”. Abbreviations must not be followed with a period unless that abbreviation spells another word. General use of abbreviations must be avoided. There must be no stacked fractions, that is, fractions shall be shown with a slash, e.g. 1/4.

Contrasting text styles or fonts are to be used within a drawing to delineate types of information. Fonts used within FAA drawings must be restricted to those shown in Table 3- 7, Comparison of Font Types. See Table 3-8, Text Heights and Line Widths, and Section 3.1.10, Line Weights, for appropriate line weights for text. The Annotation Table in Appendix A defines appropriate levels for text used in FAA drawings.

Table 3-8, Text Heights and Line Widths

3.1.9.2. Text Justification

Text justification depends upon how the text will be used in a drawing. Call out notes or local notes, also referred to as “leadered notes”, shall always be left justified regardless of which direction the leader is pointing.

3.1.10. Line Widths

The five line widths defined in Table 3-9, CADD Line Weights and Associated Plotted Widths, should be sufficient for the majority of A/E/C drawings and must not be expanded unless an appreciable improvement in drawing clarity or contrast can be realized. Any deviation shall be coordinated with the local CADD Manager. The line thickness values (in both millimeters and inches) are to be considered ‘nominal’, as adjustments may be necessary to the values used in the pen tables, in order to achieve the weights specified in Table 3-9, CADD Line Weights and Associated Plotted Widths. Typical applications for each of the line widths are described below:

a. Fine (0.006 in. / 0.15 mm). Fine lines should be used for depicting dimension lines, extension lines, leader lines, object lines “seen in the distance”, hidden lines, grid lines and patterning.

b. Thin (0.012 in. / 0.30 mm). Thin lines should be used for depicting minor object lines, including existing object lines, line terminators (arrowheads, dots, and slashes), dimension text, text for notes and callouts, and text inside schedules.

c. Medium (0.019 in. / 0.475 mm). Medium lines should be used for depicting schedule boxes and charts, most object lines, including new object lines, text for titles and underlining.

d. Wide (0.026 in. / 0.65 mm). Wide lines should be used for object lines requiring special emphasis and separating portions of drawing.

e. Extra wide (0.032 in. / 0.825 mm). Extra wide lines should be used for border only.

3.1.11. Color Usage

The use of color in CADD files is for on-screen visualization and design aid. Default color assignments are delineated in Appendix A, Layer/Level Naming Scheme. The use of other colors is allowed to provide an appreciable improvement in drawing clarity or contrast. The color yellow is reserved for highlighted graphic entities. The use of color mapping in AutoCAD drawings to represent line width is discouraged.

3.1.12. Line Types

The line styles applicable to this standard are represented in Figure 3-11, Standard Line Types. Additionally, typical custom line types are represented in Figure 3-12, Typical Custom Line Types.

Figure 3-11, Standard Line Types

Figure 3-12, Typical Custom Line Types

3.1.13. Drawing Origins

Consistent origins must be used to ensure ease of translation and attaching of reference files in both software packages.

3.1.13.1. AutoCAD Working Units and Drawing Origin

AutoCAD has an infinite design plane, eliminating limitations to the space available for drawing. Working units must be selected according to the discipline of the drawing:

architectural (feet and inches), engineering (feet and tenths), or decimal (metric). AutoCAD models should utilize real-world coordinates. AutoCAD layouts should position the origin in the lower-left corner of drawings at the Cartesian coordinate point of 0,0,0.

3.1.13.2. MicroStation Working Units and Global Origin

The global origin must be positioned in the center of the design plane to avoid loss of data exceeding the design plane. If option for True Scale is available (such as in placing cells, or attaching references), it is encouraged that the setting be turned on. Otherwise, working units must be set to those shown in Table 3-10, MicroStation Working Units.

3.1.14. Externally Referenced Files

The use of externally referenced files by MicroStation and AutoCAD allows for the viewing of all or part of a drawing file from another drawing file (host file). Only full-scale drawing files must be utilized as references. Nesting of reference files must be avoided. As files are created and referenced, reference filenames must not be changed, as it will result in the inability of the host file to find its reference files. All reference files must be included with file transfers to and from the FAA.

3.1.14.1. Specific Use of AutoCAD Reference Files

All files referenced in the host file must use the “Attach” option within the XREF command.

AutoCAD users MUST NOT use the "Save Path" method when attaching drawing files for reference.

3.1.14.2. Specific Use of MicroStation Reference Files

MicroStation users MUST NOT use the "Save Full Path" method when attaching drawing files for reference.

3.1.15. Patterning

Do not create customized patterns; use the patterns supplied with the CADD software. Use associative locks when using MicroStation, unless a pattern boundary/border is not desired.

3.1.16. Dimensioning

The labeling units for all A/E/C drawings must be units of feet and inches and fractions of an inch, with the smallest fraction usually being 1/8" or as decimals in feet, inches, and hundredths of an inch. Dimensions of less than 12" must be shown in inches or fractions of inches, and on one line with a space between the whole-inch and fraction. Dimensions greater than 12" should be specified in feet and inches (i.e.
