1: Introduction Purpose

For this update of the GSFC FMD CADD manual FMD will follow the ERDC/ITL TR- 12-6 A/E/C CAD Standard, Release 6.1., dated August 2019 as published by the U.S. Army Engineer Research and Development Center, and Autodesk 2020 products.

• AutoCAD MEP

• Revit

• Civil 3D

These standards are based on the AIA layering guidelines with Autodesk embedding AEC Title Case – Based on NCS 5.0 in its products.

Figure 1 Drawing Setup

Scope of Manual The Computer-Aided Drafting and Design (CADD) Manual provides instructions covering CADD requirements for the Goddard Space Flight Center/Facilities Management Division’s (GSFC/FMD) CADD system. All drawings produced for FMD shall follow the specifications in this manual. This document is revised on an as needed basis. This version of the CADD manual supersedes the version dated January 2010.

The CADD manual is a component of the Standard Reference Document (SRD) and the Facilities Construction Engineering and Technical Services III (FaCETS III) contract. The manual is maintained by the FaCETS III CADD Resource Group (in conjunction with the Government Technical Policy Group). The CADD manual provides specific guidance for all designers and engineers preparing CADD drawings. All users are encouraged to provide feedback and suggestions concerning these specifications to the CADD Resource Group.

The GSFC FMD CADD manual provides instructions covering CADD requirements for the GSFC/FMD’s CADD system. The GSFC FMD CADD Standards manual is intended to augment the A/E/C CADD Standard 6.1 for FMD Specific requirements.

Background NASA GSFC FMD has previously maintained detailed standards specific to FMD’s needs and requirements. With the large volume of interaction required to communicate through CADD systems it was deemed more appropriate to adhere to an established standard. The A/E/C CADD Standard 6.1 was chosen because of its unlimited distribution, development specific to federal facilities, and it is based on well-defined and accepted standards.

Structure of the Manual The main body of the CADD manual consists of specifications that apply regardless of where drawings are developed. In addition to the main body of the CADD manual, there are four Appendices. Appendix A applies only to drawings produced OFFSITE, and Appendices B, C, and D apply to those drawings produced ONSITE.

Chapter 1 Provides an introduction to the CADD manual.

Chapter 2 Specifies the software required to develop and transmit drawings.

Chapters 3-7 Specifies the general requirements to develop and as-build project drawings.

Chapter 8 Addresses the GIS Portal

Appendix A Addresses topics that pertain specifically to OFFSITE AEs.

Appendix B Addresses topics that pertain specifically to ONSITE AEs.

Appendix C Addresses topics that pertain to the CADD Resource Group As-built responsibilities for models and controlled schematics.

Appendix D Provides recommendations for efficient use of AutoCAD.

OFFSITE Architects-Engineers (AEs) are provided a version of the manual that includes all chapters up through and including Appendix A.

ONSITE AEs have access to all chapters and Appendices.

Units of Measure All work shall be in the United States Customary System (USCS–Imperial) with building models completed in units inches, and Site work completed in units feet.

As-built Models and Schematics All building model drawings are in inches; all site model drawings are in feet. Any residual Metric information is for reference only and will be replaced with Imperial information as need requires. UCS control sequences shall be completed using imperial units. These drawings are only in the Control series (86000-88999).

New Project Drawings All work shall be in the United States Customary System (USCS–Imperial) except for UCS control sequences. UCS control sequences are depicted using dual units (i.e., SI first, followed by Imperial in parentheses) in order to simplify future conversion efforts.

Legacy Project Drawings Legacy projects exist as a mixture of SI and Imperial (mostly Imperial).

Building Information Modeling (BIM) NASA GSFC FMD concurs with the direction established within the BIM Guides available at https://www.hq.nasa.gov/office/codej/codejx/Assets/Docs/2017/NASA BIM Scope S ervices Requirements Revised 2017 TAGGED.pdf

6: AEC Project Setup All Design packages are to be created using either AutoCAD MEP or Revit as directed by the PM. Use the AutoCAD MEP Project Browser to create a new Project.

FMD Utilizes a Prototype Project that can be made available to external AEs.

For Revit projects, the project directory structure located at Q:\CADD_LIBRARY\NASA_FMD_Revit_Directory_Prototype must be copied to the new project directory.

Create the Project Folder All projects shall reside at either one of the following directories based on if the project is a Work Request (WR) or a Construction of Facilities (COF)

• Q:\CADD_ACTIVE\WR\...

• Q:\CADD_ACTIVE\COF\...

If your project directory has not already been defined, create a directory in either

Q:\CADD_ACTIVE\WR\...

Q:\CADD_ACTIVE\CoF\…

Use Windows File Explorer to create the directory.

Each project must have a unique project folder directory created on the network in the appropriate Q:\CADD_ACTIVE directory. The unique number used will be the project number. The PM is responsible for having the appropriate subdirectories created for the project. The directory should be named including the project number, the building number, and a brief project description Examples: WR project E2854 completing a building 018 office modification should be named is named:

Q:\CADD_ACTIVE\WR\E2854-018-Office Modification. CoF project 00GMAZ completing a new Flight Projects building is named:

Q:\CADD_ACTIVE\CoF\00GMAZ-039-Flight Projects Building If a CoF project also has a WR number, it should be stored in the CoF folder using the CoF project code.

The directory structure under these project names should be {Project Title} as it will show in the title block for AutoCAD MEP projects.

Project Directory Structure The Project Directory is structured as follows;

Figure 10 Project Navigator

Sheet Set Properties You will enter data pertinent to ALL sheets in the project here.

Figure 11 Sheet Set Properties dialog box

Creating Constructs Constructs shall be named in compliance with the A/E/C CADD Standard 6.1 Section 2, “Electronic Drawing File Naming Conventions, Model File Naming Convention.”.

Every building project must have an Architectural construct whether there is Architectural work involved or not. The Architectural model is externally referenced into all other discipline base building models.

Every site project must have a Civil construct. The Civil construct is externally referenced into all other discipline base site models, if they exist. It is recommended that all site work be shown in the Civil construct regardless of discipline.

All constructs must be externally referenced (XREF) at 0,0,0 to maintain orientation with the As-built database. This is accomplished by dragging and dropping constructs into the current drawing file. All model drawings must be externally referenced in Tilemode 1, model space.

The Mechanical Engineer externally references (XREFs) the Architectural construct into the Mechanical construct. The Electrical Engineer XREFs the Architectural construct into the Electrical construct. The Civil construct is externally referenced into all other discipline specific site base constructs.

Items located in model space in the model should include:

• Annotation related to sizes of devices, wiring, piping, duct work and other similar information

• Externally referenced (XREF’ed) design constructs pertinent to the project

• Information needed for construction and call-outs that point to specific items on construct drawings that must not be affected by moving the viewport

• Note tags (i.e., callouts)

• Point of connect/disconnect symbols

Figure 12 New Construct dialog box

Creating Sheets Sheets shall be named in accordance with the A/E/C CADD Standard 6.1 Section 2, “Electronic Drawing File Naming Conventions, Sheet File Naming Convention.”

All Sheets shall be created within the Project manager. The default sheets size is D-size (24x36). All details, schedules, notes, and information pertaining to project specific construction should be located in the “Sheets” drawings. Do not place any of the specific construction instructions in the model. This list is not all-inclusive, it is meant to be more of a general placement guide for information (i.e., either paper space or model space).

Items located in layout tabs should include:

• Abbreviation list

• General annotation (i.e., notes)

• Information needed for construction that is not affected by moving the viewport

• Schedules

• Symbol—Material list

• Titles

Figure 13 Title Block

Signatures and Stamp

For ONSITE AE, refer to the FaCETS III contract for Seal requirements.

For OFFSITE AE, final drawings shall always be stamped.

Printable Drawing Sheet Numbering The PM is responsible for reserving all sequential numbers necessary for all project drawings prior to the 90 percent submission printing.

For OFFSITE AEs, the sequential numbers shall be provided by the NASA PM prior to the 90 percent submission.

As-built Project Drawing Development: As-builting Upon construction completion, after construction contractor redlines have been received and approved as complete and correct, the project drawings are updated by the AE with this information. The As-built project drawings are updated using layers as previously described in Chapter 7 (generally using the –N and –D layers. The –C layer is used only to correct the background information discovered to be incorrect either during the design or the construction).

OFFSITE AEs shall return the contractor redlines and the final As-builts to the PM.

ONSITE AEs shall follow the requirements in Appendix B.

After the project drawings are updated and approved, the PM ensures that the drawings are posted in the appropriate directory and notifies the CADD Resource Group that the As-built drawings are ready for incorporation into the FMD As-built directories.

Sheet Properties To access and modify sheet data select the Sheets tab and select the sheet that you wish to modify with the right mouse button, and then select Properties.

7: Layering Conventions FMD Layering Conventions

The layers that are in active use at GSFC are integrated into the applications. FMD utilizes several layering standards, as shown below:

• For Buildings refer to the A/E/C Computer-Aided Design (CAD) Standard Release 6.1, Appendix A: Model File Level/Layer Assignment .

• For Buildings, FMD uses the AEC Title Case – Based on the NCS 5.0 that is imbedded in Autodesk 2020 based products. Use the New Layer from Standard to create required layers.

Figure 16 New Layer from Standard

• For Site, consult with the FaCETS III Site Team Lead, in conjunction with the Government Technical Policy Group. All new layers created must be routed through the NASA FMD Information Resources Manager. The CADD Resource Group will review the layer with the Government Technical Policy Group.

• For ESRI GIS Site, FMD complies with the SDSFI Standards.

Suffixes for Layering Conventions The use of the suffixes in layer names allows the FMD CADD Resource Group to extract only modified information from project drawings for incorporation into As-built models. Suffixes allow changes indicated by designers to be accurately identified and reincorporated in the As-built and As-designed drawings.

Existing Existing conditions that are not Corrections, Demolition, or New Work. Existing conditions utilize the root layer with no suffix.

Demolition Demolition utilizes the appropriate root layer with a “-D” suffix. AEs will specify this as DEMO (cut from EXISTING).

New Work New Work utilizes the appropriate root layer with a “-N” suffix. AEs will specify this as NEW work (added to EXISTING).

Corrections Corrections utilizes the appropriate root layer with a “-C” suffix.

This will be corrected information per AE field verification.

Color and Pen Weight FMD Utilizes the AIA Standard.ctb as provided by Autodesk. Any color choices that need to be made concerning

FMD Standard Drawing Sheet Layout All standard project drawings are required to contain elements that are located in specific places on the drawing. When creating a new drawing, follow the example in the succeeding figure.

Figure 20 Standard Drawing Sheet Layout

1. Key Plan - The Project Architect for each project is generally responsible for the key plan and indication of the work area using the AutoCAD BHATCH command. If the project does not call for architectural work, the project Lead is responsible for the key plan and crosshatching the work area. The key plan is an AutoCAD WBLOCK that is copied into the project as a construct. Name the construct KEYPLAN. All drawings must include the key plan. This adds consistency to the project. It is the project Architect/Lead’s responsibility to construct new/updated key plans as designs are implemented. The new/updated files are to be provided to the CADD Resource Group for updating.

2. North Arrow - The key plan includes a standard north arrow, as depicted in the succeeding figure. The north arrow is assumed PLAN north unless otherwise specified. The PLAN north should always be shown either pointing up or pointing to the left in the drawing. A true north arrow can also be included in the drawing if it is needed. Use the same style arrow that is used to indicate the PLAN north with TRUE NORTH annotated below the arrow.

3. Graphic Scales - All drawings are to include a graphic scale (Bar scale) to indicate the scale used in the drawing.

4. Drawing Titles - Insert drawing titles in Paper Space. Left justify titles under the plan, detail, etc., that they are describing. The standard title layout will utilize AutoCAD MEP’s Title Mark. The Autodesk program controls all the fonts, heights, and widths.

5. Viewport - All model work is done in the constructs and referenced into the drawing through a viewport.

6. Drawing Notes - Use the same text, font style and underline for the note title as is used for the drawing titles, with the exception of the bubble. Notes should be plotted at pen weight 2, and titles should be at pen weight 1. A drawing with more than one discipline should arrange the notes by discipline, with separate titles for each group.

7. Schedules - Use the same text, font style and underline for the schedule as used for the drawing notes. The schedule is located below the notes.

8. Scope of Work - Use the same text, font style and underline for the Scope of Work as used for the drawing notes. The Scope of Work is located above the title block.

Annotation Text Height Annotation throughout the drawing package will be 3/32” Height, romans.shx, Width factor 1. AutoCAD MEP is configured to use this when using the Annotate command.

Drawing Titles Insert drawing titles in Paper Space. Left justify titles under the plan, detail, etc., that they are describing. All titles are plotted at pen weight 2. The standard title layout will utilize Autodesk’s AEC, ANNOTATION, TITLE MARKS command. The Autodesk program controls all the fonts, heights, and widths.

Figure 21 Typical Drawing Title with Bubble

Drawing Notes Use the same text, font style and underline for the note title as is used for the drawing titles, with the exception of the bubble. Notes should be plotted at pen weight 2, and titles should be at pen weight 1.

A drawing with more than one discipline should arrange the notes by discipline, with separate titles for each group.

Figure 22 Construction Notes

Schedules (or other detailed information, if applicable) Use AutoCAD MEP’s Schedules for room finish schedules.

Figure 23 Schedules

Scope of Work (if applicable) Use the same text, font style and underline for the Scope of Work as used for the drawing notes. The Scope of Work is located above the title block.

Figure 24 Scope of Work

Dimensioning All dimensioning is done through the active model space viewport from paper space, TILEMODE (0). Click the Scale to Paper Space checkbox from the Geometry dialog box as accessed from the Dimension Style dialog box under the Format pull-down (Autodesk). This will enable Paper Space dimensioning which takes into account the viewport scale. Text height and font specifications are based on FMD standards as previously mentioned. Architectural Tick is the required dimension arrowhead, as depicted in the succeeding figure.

Figure 25 Typical Dimensioning representation

Leaders Most of the leaders use arrows. Use loop leaders when designating pipe and wire sizes. Insert leaders in Model Space. See the examples in the succeeding figure.

Figure 26 Typical Leader Representation

Symbols Several basic identification symbols are used, as shown in the succeeding figure.

Place all of these call-out symbols in model space.

General

Figure 27 Typical Callout Symbols

Discipline Specific Requirements Abbreviation and Legend Sheets The standard FMD Abbreviation and Legend sheets are template drawings utilizing Autodesk symbology and other non-Autodesk symbols, as indicated in the legend. All FMD standard symbols and attributes are to be adhered to. Use Autodesk symbology as designated on the Legend sheets. When non-Autodesk symbology is indicated on a Legend sheet, it will be necessary to copy the symbology for use within the project.

Standard Discipline Details The individual engineering disciplines have developed certain standard details that meet the standards of FMD. Approved details are stored in an APPROVED folder.

Review only the approved details to determine which may be appropriate for the project. When a detail exists, and it meets the requirements of the project, the standard detail should be utilized to the greatest extent possible. However, project requirements shall always govern. Adjust standard details to the project as necessary. The following is a list of available folders:

• ARCHITECTURAL

• Bar Scales—contains bar scales only, no discipline details

• CIVIL

• ELECTRICAL

• ENVIRONMENTAL AND HAZARDOUS—the environmental details were obtained from the Maryland Standards and Specifications for Soil Erosion and Sediment Control. The file name in the folder indicates the page number of the drawing in the Maryland book.

• FIRE PROTECTION

• KEYS—contains plan keys only, no discipline details

• LANDSCAPING

• MECHANICAL

• PLUMBING

• STRUCTURAL

Goddard Operation, Maintenance, and Repairs system

(GOMARS)

The Goddard Operation Maintenance And Repair System (GOMARS) is used by the FMD to identify equipment and to track maintenance and repairs. The GOMARS numbers are used mainly on drawings (generally in plans and schedules) to identify equipment. The gomars.xls file provides designers with a guide indicating the type of equipment requiring GOMARS numbers, their various naming formats, and specific GOMARS processes to be followed. Unique equipment numbers (actual numbers to be placed on drawings) must be obtained from the Government’s Construction, Operations, and Maintenance Branch (COMB) during the design process.

Room Tags

Door Tags Door tags contain attribute information – Door Identification, Size, Material, and Fire Rated (y/n). Layer – A-DOOR-IDEN. Requirements are as shown in the Architectural Legend:

Coordination with Site GIS As-built Database Designers must be acutely aware that upon completion of site projects (or projects with site work), that the project drawings are incorporated not only into CADD As-built databases, but also into a distinctly separate GIS database. Therefore it is critical to take into consideration what information is to be included in the design drawings along with inherent properties of the linework being created. The following guidelines are provided to facilitate the transition.

Attribute Data The structure of the GIS database has vastly greater capabilities to record attribute data about system elements (i.e., pipes, valves, manholes, etc.) than does CADD capabilities. However, the format whereby GIS records information is a very precise set of attribute tables that have been defined in exact terms as to how and what information FMD wants to store for the various elements.

For information to be extracted from CADD project drawings to the GIS database involves intensive manual efforts broken down into two components: copy/paste efforts, and find/retype efforts. The copy/paste work generally is the transferring of spatial elements (points, lines, polygons) that represent valves, pipes, roads, etc.

The find/retype work generally is the transferring of attribute data (invert elevations, top of pipe elevations, GOMARS numbers, valve type, size, etc) that are associated with the spatial data. It is the find/retype work that is most prone to being impeded during this process by CADD project drawings that are 1) incomplete, 2) difficult to interpret or extract information from, and 3) use of attribute data that is contrary to the GIS requirements. Each of these contrary practices is discussed below. Attribute tables vary in size according to the type of spatial element under consideration. For discussion purposes, a sample system element has been arbitrarily chosen to illustrate the intended points.

Sample: The Chilled Water System, Well element, has 12 engineering specific attribute data fields capable of recording the following data:

• Pump inlet elevation, ft

• Pump top elevation, ft

• Pump GOMARS

• Screening top elevation, ft

• Screening bottom elevation, ft

• Cover/casing outer diameter, in

• Casing top elevation, ft

• Top of water elevation in well, ft

• Depth of well, ft

• Size, in

• Type (for this particular element, only one Type–“non-potable” has been defined by FMD) · GOMARS

Spatial Data All utility linework shall be contiguous lines or polylines with all ends or changes in directions placed at the correct coordinates and elevations using the system specific definition (ex: Top of pipe, Bottom of pipe, etc.) as defined in the GIS Data

Dictionary. All linework endpoints shall have the correct coordinates and elevations along with the specific data associated with each endpoint.

Utility lines can consist of lines and arcs as segments or polylines. Continuous runs shall be indicated with a single line or polyline segment. Changes in elevation or direction are acceptable endpoints for line segments with the correct coordinates and elevations.

There shall be no gaps between line segments for an individual utility run. The coordinates for the endpoint of a line segment shall be the exact coordinates for the starting point of the subsequent line segment.

Assembling the Printable Drawing Construction Package Drawing Set Organization The FMD generally follows the Construction Specification Institute (CSI) and the Uniform Drawing System (UDS) drawing set organization standards with the exception of the ones not used by FMD as indicated in the succeeding figure. CSI- UDS standards cited here are for reference. Organize drawing sets accordingly.

Content Content order within each subset will be as shown in the succeeding figure:

Figure 32 Subset content Order

Additional requirements for all disciplines include the following:

Discipline Legend sheet should be the first drawing within the individual discipline subsets

Demolition drawings should precede new work

When architectural plan areas are segmented within levels (in order to fit on the printable drawing), all subsequent work units (as well as all other disciplines) should follow the same segmentation

Fire Protection Detail For large projects, Fire Protection drawings should include separate sub discipline drawings for Fire Suppression Systems (i.e., sprinklers, standpipes) and for Fire Alarm/Detection Systems. On smaller projects, they can be combined on a single plan if appropriate. Demolition drawings for both sub disciplines should be grouped, followed by New Work drawings for both. Under both demolition and new work, the plans will be followed by other drawing types as applicable, in the order shown:

• Fire Protection Legend

• Demolition o Plans

• Fire Suppression

• Fire Detection and Alarm o Large Scale or Partial Plans (order of sub disciplines same as for plans) o Elevations (order of sub disciplines same as for plans) o Sections (order of sub disciplines same as for plans) o Details (order of sub disciplines same as for plans)

• New Work

As-built Project Drawings Upon construction completion, after construction contractor redlines have been received and approved as complete and correct, the project drawings are updated by the AE with this information. The As-built project drawings are updated using layers as previously described in Chapter 5 (generally using the –N and –D layers. The –C layer is used only to correct the background information discovered to be incorrect either during the design or the construction).

• OFFSITE AEs shall return the contractor redlines and the final As-builts to the

PM.

• ONSITE AEs shall follow the requirements in Appendix B.

After the project drawings are updated and approved, the PM posts the drawings in the appropriate directory, and notifies the CADD Resource Group that the As-built drawings are ready for incorporation into the FMD As-built directories.

8: GIS Portal GIS Portal

FMD GIS data is available on the GSFC Intranet through the GIS portal at http://gsfcgis.gsfc.nasa.gov/. This includes information available to the GSFC community that is restricted to non-CUI data and specialty maps with restricted data for Engineering, Operations and Maintenance, and Planning. The user interface includes Home, Public, Building Plans / Space Utilization, Environmental/Engineering, and Planning tabs each containing a series of maps tailored to specific requirements.

This portal is only available to users on the NASA Intranet and certain data is available to approved authorized users. If a project requires GIS data be made available to external users, the PM should extract the data and provide a secure method to transfer the data following the requirements for CUI data if the contents include utility data.

GIS Data Updating Procedure The update process for GIS models is straightforward. Once the information is received by the CADD Resource Group manager, the quality of the As-built is inspected. If it is acceptable, the following basic operations are performed:

• Necessary linework and symbols are transferred to the appropriate layers

• Demolition linework and symbology within the existing drawing is removed

• Symbol designations are inserted onto appropriate layers

• Sizes are transferred to appropriate layers

• Imported into GIS model

• Attribute data populated

If the information is incomplete, it is returned (with comments) to the PM via the CADD manager. The GIS models are maintained in an “As-built” status.

Project Drawings Drawings for projects are available via the network as indicated above. They are located in Q:\CADD_ACTIVE\WR or Q:\CADD_ACTIVE\CoF. These directories are used both to develop project drawings for design and to record the project’s As-built changes after construction. If the files in either directory are not used within a thirty-day period, they are automatically archived by the CADD Resource Group to one of the following inactive directories: Q:\CADD_INACTIVE\WR or Q:\CADD_INACTIVE\CoF. The CADD_INACTIVE directory is write-protected;

therefore, the necessary drawing files must be copied back into the appropriate CADD_ACTIVE directory for use.

The following directory structure will be generated under the project name when using the designated prototype project.

Abbreviations and Legend Sheets The Abbreviation and Legend sheets are available in the Q:\CADD_LIBRARY\APPROVED\STANDARDS\Legends directory. Hazardous & Environmental and Landscaping legends are currently placeholders only. No symbology is contained on these sheets.

Standard Details Standard CADD details are organized and indexed in a manner suitable to each discipline. Approved details are found in Q:\CADD_LIBRARY\APPROVED\DETAILS\{discipline}\{filename}. If the folder is empty, it is currently being used as a placeholder for details in the process of being developed. Unapproved details are found in Q:\CADD_LIBRARY\UN- APPROVED\DETAILS\{discipline}\{filename}. Several groups are responsible for developing, promoting, and maintaining Standard Details as shown below:

CADD Resource Group — the CADD Resource Group is responsible for posting approved standard details.

Discipline Committees — the Discipline Committees are responsible for developing the CADD Standard Details for their discipline. Anyone may initiate a proposed Standard Detail.

Government Technical Policy Discipline Lead— The Government Technical Policy Discipline Lead is responsible for promoting development of Standard Details to the Discipline Committees. Additionally, the Government Technical Policy Discipline Lead is responsible for detail approval (in conjunction with the discipline committee), as well as to inform and provide approved details to the CADD Resource Group.

Formatting Drawing Numbers for Printable Drawings Use the format in the succeeding figure to develop both the information needed in the drawing title blocks, and proper numbering for all project drawings. {G}{Sheet size}–{Building number & letter (or Site)}–{Sequential number} Example: Project in Building 16W, using sheet size A1, and the next available sequential number from the DrwgNumb.xls log of 12345: GA1–016W–12345 Example: Project in Site, using sheet size D, and the next available sequential number from the DrwgNumb.xls log of 23456: GD–SITE–23456 WR/CoF project file drawings are in the sequential series 00001-59999

Reserving Numbers for Printable Drawings Drawing numbers are obtained and documented using the DrwgNumb.xls file located in the P:\drawing numbers folder. Instructions are included in this file.

Incorporating Redlines into As-builts

Redlines will be incorporated into the AutoCAD drawing files, and the revision block will be marked to indicate that the update has been completed per As-built conditions. Record of the completion of this action must be submitted to the government via a “Material Approval Submittal Transmittal” form for the proper customer review cycle. Upon completion of these actions, and receipt by the CADD Resource Group, the completed work will be integrated into the composite building models, or site plan, as appropriate.

Appendix A: Offsite AE Processes

Requesting As-builts to Start A Data Request form (DataRequest.doc) will be submitted to obtain electronic copies of drawings. This form is part of the CADD Resource Group information provided by the PM. Complete the request form and return it to the PM. Drawings are available to OFFSITE AEs at the PM’s discretion. Most content will be considered Controlled Unclassified Information (CUI). If this is the case a CUI letter will need to be obtained from FMD’s CSO (Computer Security Official).

Standards for CADD Work The AE must verify that they have the requisite standards with which to begin

• AEC Title Case – Based on the NCS 5.0 that is imbedded in Autodesk 2020 based products

• GIS Data Dictionary (SDSFIE)

• GOMARS Conventions (gomars.xls)

Template Files The AE must verify that they have the requisite electronic template files with which to begin as shown below:

• As-builts of Existing Conditions

• AutoCAD MEP NASA FMD Prototype Project

• Revit Discipline specific project Templates

Project Drawing Development During the design phase, the AE shall be providing milestone submissions in both print (for Engineering Branch review), and electronic AutoCAD MEP or Revit based files (for CADD Resource Group review) formats. The CADD Resource Group review comments shall be returned to the AE via the Government PM, accompanied by the Engineering Branch comments.
