Appendix A – Computer Generated Drawings 1 of 3

CRITERIA FOR COMPUTER GENERATED DRAWINGS

A. INTRODUCTION

FDCC’s CAD Standards are intended to be simple and only address the most fundamental of requirements for 2D CAD drafting. Any questions regarding these Standards should be directed to FDCC’s CAD Manager.

B. GOVERNMENT PROVIDE INFORMATION AND ITEMS

Before the development of any CAD drawings, FDCC will provide the following electronic files:

GENERAL_SYMBOLS.dwg FDCC A-Landscape JUN2009.dwt FDCC A-Portrait JUN2009.dwt FDCC D Civil SEPT 2009.dwt FDCC D Sheet-JUN2009.dwt FDCC MODEL SPACE.dwt fdcclant.stb

C. DRAWING SHEET FILES AND BORDERS

Standard paper space drawing sheets with borders/title blocks shall be used.

The following Paper Space AutoCAD templates shall be used:

FDCC A-Landscape.dwt -“A” size sheet (8.5” x 11”) (landscape)

FDCC A-Portrait.dwt -“A” size sheet (8.5” x 11”) (portrait) FDCC D Sheet.dwg -“D” size sheet (34” x 22”) FDCC D Civil.dwg -“D” size sheet (34” x 22”)

All CAD drawings shall use the FDCC titleblock templates furnished to the Contractor by the Government.

The design, configuration and attributes of this titleblock shall not be altered in any way. The Government uses a file management software program, “Adept”, which extracts data from the attributes in each of the titleblock fields. If the attributes are changed, the data will not be readable by Adept and therefore make the drawing irretrievable. The Contractor’s electronic drawing files will be checked at each submission for compliance, and if they are not acceptable, the Contractor will be required to insert new titleblocks and edit the fields appropriately.

All CAD drawings shall be created from editable vector entities. Inserting a PDF drawing into a CAD title block is not acceptable.

D. SOFTWARE

USCG Civil Engineering Units and FDCC use AutoCAD 2017 software to develop 2D design and construction drawings. Contractor produced design and construction drawings may be prepared in Revit. If Revit is used to produce design or construction drawings, interim progress submittals must include editable 2D DWG AutoCAD 2017 electronic files for site plans and floor plans. These site and floor plans may be used by FDCC for developing other plans for furnishings and equipment. At all submittals, drawings, specifications, calculations and data shall be supplied in Adobe “pdf” format.

All As-built drawing files shall be 2D DWG files editable by AutoCAD 2017. Each As-built CAD drawing shall be a separate “dwg” file using the FDCC titleblock; multiple sheets may not be combined into one file.

E. LAYERS

Appendix A – Computer Generated Drawings 2 of 3

Layers allow for graphic information to be grouped for display and plotting purposes. They are the BASIC CAD tool for managing visual information. Proper use of layers reduces drawing time and improves drawing coordination.

It is absolutely essential that layering is used, and that the naming format standards comply with the latest edition of CAD Layer Guidelines published by the American Institute of Architects.

F. COLORS AND LINE WEIGHTS

Colors: AutoCAD allows drawings to be plotted based on “Plot Styles” and “Color Dependent” plotting. FDCC uses Style based plotting, but will accept drawings developed for Color Dependent plotting. The A/E must provide their “ctb” file with their drawings files.

Line Weights: Line weights shall be assigned “By Layer” and shall be appropriate to produce a legible and easily read drawing when produced as half-size (11” x 17”).

G. TEXT AND FONTS

Text: The USCG requires the use of ROMANS.shx font for general notes and text entities on Construction Documents. ROMAND.shx may be used for titles and special text where a bold font is needed. All text should be placed to an appropriate LAYER. It is suggested that basic notes be 0.35 line weight. For larger text such as titles, the weight could be thicker. The Multi-line text feature of AutoCAD must be used for multi-line text so that word wrapping can be utilized.

The height of general annotation text when plotted full-size shall be no less than 0.10” high.

H. FILE NAMING & DRAWING NUMBERS

Files shall be named in accordance with the FDCC’s Adept File Naming Guide (see Appendix C).

I. PROJECT FILING STRUCTURE

All CAD Model and Sheet files, Xref files and attached or embedded files (jpg, bmp, tiff, etc.) shall be kept in one folder titled “Drawings”.

J. ABBREVIATIONS

The use of abbreviations in notes and annotations is acceptable. However, if they are used, a complete list of abbreviations with their meanings shall be provided on the drawings. Separate abbreviation lists may be used for each discipline as long as none conflict. Common abbreviations shall be used throughout disciplines. Do not use different abbreviations for the same meaning.

K. DRAWING UNITS & DIMENSIONS

All discipline drawings shall be drawn and dimensioned in feet and inches, with dimensions rounded to 1/8”.

The exception is civil and site plans, which shall be decimals of a foot with dimensions rounded to 1/100 of a foot.

L. SYMBOLS & CONVENTIONS

The following symbols and conventions shall be utilized and provided:

1. North Arrow for every plan

2. Graphic scales for every sheet, for every scale used

3. Titles for each object or graphic drawn (e.g. floor plan, elevation, detail, section, etc.)

4. Legends to clearly define each line type, hatch pattern and symbol used

Appendix A – Computer Generated Drawings 3 of 3

5. Location and vicinity maps shall be provided on the drawing cover/title sheet.

6. Section and detail bubble symbols shall be three-part symbols that provide: a number or letter for the section and detail, sheet number where the detail or section occurs, and at least one sheet where the detail or section is referenced from.

M. USE OF EXTERNAL REFERENCES (XRFES)

External references for site plans and floor plans shall be used to ensure that all sheets that contain the same plan are the same. Xrefed plans shall be used across disciplines (i.e. mechanical, electrical, plumbing and other similar drawings shall utilize the architectural or civil xref plans). Do not use of Xrefs for details and other drawing items that are only used on one drawing sheet. Xrefs shall not have dimensions, text and other similar annotations contained within them; they shall essentially be graphic drafting. The exception to this is that civil Xrefs that contain data populated by survey software is permitted.

Photo images and other graphics (scanned TIFF or JPEG files) may be used where appropriate. External files such as schedules, lengthy text notes, graphs, etc. shall not be used unless approved by the FDCC CAD Manager.

As-built/Record CAD DWG files: As mentioned previously, the USCG utilizes a file management and retrieval system that stores as-built/record drawing files. This system requires that each drawing be complete without the use of Xrefs. Therefore, after as-builts are complete, all Xrefs shall be “bound” into the drawing. All image files shall be embedded into the drawing as OLE objects.

N. TITLEBLOCK FIELDS

Most Titleblock attribute fields are self-explanatory, but for the sake of clarifying those that are not, the following examples/guidance is provided:

Property Name: Station building, pier/wharf, administration building, galley/dining, barracks, etc.

Unit Name: Station XYZ, Base Support Unit XYZ, Training Center XYZ, USCG Academy, etc.

Project Title: Use the official title of the project as provided by the FDCC Project Manager Unit Name: Use abbreviations for states (e.g. VA, NY, FL). Do not spell out the state names.

Project Engineer: [leave blank] Date Approved: Date FDCC approved Final Drawings Branch Chief: [leave blank] Approving Officer: [leave blank] Project Number: Official USCG Project Number (e.g. 08-L9001, 01-3047134) Technical Director: [leave blank] CAD Drawing Number: Number will be provided by FDCC Design Project Manager upon request Issue Fields: List each submission type and date Mark: Number (e.g. 1, 2, 3, 4, etc.)

Date: Date of Submission or revision (mm/dd/yyyy) Description: Type of submittal (e.g. 65% Design, Pre-final Design, Final Design, Revised Final Design, As-Built or Record Drawings, Misc. Revisions, etc.)

O. DRAWING REVISIONS

Revisions to drawings after Final Approval shall be clearly annotated with revision clouds and symbols, and number. Each revision number (Mark), Description and Date shall be entered into the Issue field of the titleblock.
