  • Overview
    This computer aided drafting (CAD) guideline is for use on State of Minnesota facilities. These standards have been developed to serve as a guideline for the development of contractually required electronic data submittals to Real Estate and Construction Services (RECS). Consultants shall be responsible for obtaining the  most  current release  prior to  the  commencement  of  any  work.  Click to view the entire document

  • 1.0 General Requirements
    The Consultant shall provide three sets on CD ROM, labeled, CAD and PDF record file drawings. These files shall include all record drawings and specifications for which the Consultant has generated. Files shall be submitted in AutoCAD Release 2004 or higher up to Release 2010 DWG and PDF format.  These files are to be updated during construction to represent as-built conditions.  Refer to Appendix A Checklist.

    It shall be understood that the CAD drawings themselves are not record drawings. If the Consultant is unable to comply with this provision, arrangements must be made for generating vector-based computer drawings prior to executing a consultant agreement with the State of Minnesota. The Consultant should contact RECS to make such arrangements.

    Individual specification sections are not to be listed on the disk label.
    Limit file listing on text files to “SPECIFICATIONS”.

  • 2.2 File Description

    Each disk is to be accompanied by a file description shiet aon 8 ½" X 11" hard copy print out.  Each file description sheet is to include the following information:

    REMARKS

    See Appendix B - Sample File Description Sheet

  • 3.0 - 3.3 Required File Types, Text and Drawing Files and Photographs
    3.0 REQUIRED FILE TYPES 

    Both text and graphic type files will be included in the electronic data deliverables. All files may be submitted on the same disk provided that all files of like type are on only one disk.  If not, then they are to be submitted on separate disks.

    3.1 TEXT FILES 

    Text files are to be saved in either Microsoft Word (.DOC), Rich Text Format (.RTF) or in PDF format.  No other file formats will be acceptable for text files.

    3.2    DRAWING FILES 

    All files are to be submitted in DWG format (File Format 2009-2010) and a separate PDF file for each sheet in the document set. Any submittal found to have DWG format or PDF format drawings missing will be rejected.

    All drawing files that are incorporated via xref are to be included on the disk.  Any submittal found to have missing xref’s will be rejected.

    Raster images are not acceptable. All graphic images in the drawing files are to be vectorized images.

    All files are to be delivered on CD-Rom or DVD-Rom accompanied by the 8 ½ x 11 hard copy file description and prints of PDF files. No compressed files (e.g. .zip) are acceptable.

    3.3 PHOTOGRAPHS

    All photographic images that are part of the electronic record for the project should be submitted on CD-Rom or DVD-Rom along with the rest of the record drawings.
  • 4.0 - 4.1 Suggested Guidelines and File Naming

    4.0  Suggested Guidelines

    4.1 File Naming

    The following is a guideline for naming sheet files and model files.  if your firm has a standard for naming sheets and model files, that standard may be followed.  Please submit documentation as to what that naming structure is for references.

  • 4.1.2 Sheet File Names

    Sheet File names start with the discipline code, followed by a user-definable numerical field that closely corresponds to the sheet sequence number. For example A-101 for architectural, floor plans, first floor.

    Discipline is the primary method of classification for both file names and layer names.  The discipline code provides a path back to the originator of the data.  The code also provides a logical categorization of the CAD information.

    Discipline Codes Sheet Type Designators
    A Architectural 0 General (symbols, legend, notes)
    C Civil 1 Plans
    E Electrical 2 Elevations
    F Fire Protection 3 Sections
    G General Information (non-discipline specific) 4 Large scale plans
    H Hazardous Material 5 Details 
    I Interiors 6 Schedules and Diagrams
    L Landscape 7 User Defined 
    M Mechanical 8 User Defined 
    P Plumbing 9 3D views 
    Q Equipment 
    S Structure     
    T Telecommunications
    X Other Disciplines
    Z Contractor/Shop Drawings 

    Sheet Sequence Numbers 

    Sheet numbers should be designated sequentially starting at “01” and continuing thru “99”

    Examples:

    The following are sample sheet file names:

    A-101.dwg        Architectural, first floor plan, sheet 1.1
    A-102.dwg        Architectural, second floor plan, sheet 1.2
    A-103.dwg        Architectural, first floor reflected ceiling plan, sheet 1.3
    A-201.dwg        Architectural, elevations, sheet 2.1
    A-501.dwg        Architectural, details, sheet 5.1

  • 4.1.3 Model File Format

    Model File names start with the discipline code, followed by a two letter drawing type, followed by a user-definable field.  For example, A-FP01 for Architectural, Floor Plan, First Floor.
