About this file
This document provides standards for drawings related to federal construction projects at Detroit Arsenal facilities. It specifies requirements such as paper sheet sizes of Arch D or Arch 30, use of Arial font at minimum size of 1/8 inch, distinguishing existing items with light lines and new items with bold lines. Standard blocks and levels are to be used according to National CADD Standards and A/E/C CADD Standard guidelines. Drawings are to reference repeated elements and follow naming conventions including discipline codes, plan types, floor numbers, and sheet sequences. The solicitation seeks a multiple award task order contract for design-build and design-bid-build construction services in support of sustainment, restoration, modernization, repair and minor construction of buildings, structures and other real property at Detroit Arsenal, Selfridge Air National Guard Base and other locations through fiscal year 2025.

DPW Drawing Standard
Paper Sheet Size: Drawings are to be drawn on Arch D (24 inches x 36 inches). Depending on the perimeters dictated by the project the Contractor may choose to consider the use of Arch 30 (30 inches x 42 inches) With written approval from the Contracting Officer's Representative.
Fonts: DPW standard font should be Ariel unless project dictates otherwise.
Text Heights: Note text should be min. 1/8”, 3/16” max. Title text should be 1/4” min.
Line Weights: Existing to be depicted in a light (thin) line weight. New to be depicted in a heavy (bold) line weight.
Guidelines can be found in National Cadd Standards.
Blocks: Commonly used elements such as, north arrows, title blocks, key plans, etc. can be found in:
T:\IMCOM\DPW\Engr_Div\Drawings_DTA\Standard_DTA_CADD_Drawing_Folder\STANDARD NOTES
DETAILS AND SCHEDULES\GENERAL. The items included in the folder above shall be used to ensure consistency in DTA drawings. Available upon request to contractors.
Level Naming: Levels are to be named according to the latest edition of the A/E/C CADD Standard (National CADD Standard) located at the following link https://cadbimcenter.erdc.dren.mil/default.aspx?p=a&t=1&i=7
The standard format for AIA long format layer names is:
D‐MJGP‐MNGP‐USDF
Where "D" represents the major group identification which corresponds to the drawing disciplines ‐ "A" for Architectural, "C" for Civil, "E" for Electrical, etc. The next four characters "MJGP" are defined as the
"major groups" within the discipline identification. Some AIA major groups are "FNDN", "WALL", "SLAB", etc. The next four characters "MJGP" are termed the "minor groups" to further subdivide the major groups.
The layer name need not contain the last four characters, "USDF", as this is the user‐defined modifier and is added at the user's discretion.
For example:
C‐WALL‐CMU would be the level for the concrete masonry units in the exterior walls on structural drawings.
A‐WALL‐CMU would be the level for the concrete masonry units in the exterior walls on the architectural drawings, while
A‐WALL‐GYBD would be the level for the gypsum board construction in the exterior walls on the architectural drawings, and
A‐WALL‐GYPD‐REN would be the level for gypsum board renovation in the exterior walls of architectural interiors drawings
All contractor work is to be put on a layer/level designated as new or demo using the above described naming convention.
Referencing: DO: Floor plans and images that are repeated in drawings throughout the project sheets, e.g. site plans, floor plans, diagrams, etc. are to be referenced in.
DO NOT: Elements such as notes, details, schedules, key plans, location maps, etc. are not to be referenced.
File Naming Convention
Example: A‐FPXXX.DGN
The first character represents the discipline, as listed below:
Discipline Character
General G
Survey and Mapping V
Hazardous Materials H
Civil C
Geotechnical B
Landscape L
Structural S
Architectural A
Interiors I
Equipment Q
Fire Protection F
Plumbing P
Mechanical (HVAC) M
Electrical E
Telecommunications T
Process D
Resource R
Operations O
Other Disciplines X
Contractor/Shop Drawings Z
Note: The second character is usually a hyphen but may be used, to describe a plan type by adding a letter character instead of a hyphen. For example, if the second is describing a Kitchen Equipment Plan, the file name will be QKFPXXX.dgn.
The third and fourth characters represent the drawing type code as listed below:
Discipline Code Definition
Al l Disciplines
FP Floor Plan
SP Site Plan
DP Demolition Plan
QP Equipment Plan
XP Existing Plan
EL Elevation Plan

The fifth and sixth characters represent the floor number, e.g. X1 = Basement (1st sub level) plan, F1= first floor plan and F2 = second floor plan.
Note: All drawing codes listed above are the most commonly used. For more options please see The AEC CADD Standard 2009 located at the flowing link https://cadbimcenter.erdc.dren.mil/default.aspx?p=a&t=1&i=2
The last character represents the sheet number sequence in the series of references, 01 being the first and then proceeding sequentially.
Sheet and File Naming Conventions
Project drawing sheets are grouped by a sheet type prefix that specifies the discipline.
Sheet Type Prefixes Disciplines G General H Hazardous Materials
V Survey/Mapping B Geotechnical C Civil
L Landscape S Structural A Architectural I Interiors F Fire protection P Plumbing M Mechanical (HVAC)
E Electrical T Telecommunications
Sheet Numbering
The drawing sheet is numbered with a prefix and followed by a single digit number that refers to a type of drawing and a double digit number that refers to the drawing order. This method allows adding sheets without having to renumber all sheets.
Numbering Series Description
A‐001 Index, Symbols, Abbreviations, Notes, Location Maps A‐101 Demolition, Site Plan, Temporary Work A‐201 Plans, Room Finish Schedules, Door Schedules, Key Drawings A‐301 Elevations A‐401 Sections A‐501 Details A‐601 Schedules and Diagrams A‐701 User Defined A‐801 User Defined A‐901 3D Representation (Isometrics, Perspectives, Photos)
When a project includes multiple sites or buildings, it is important to identify each drawing files for clarity. This is to be done as a part of the sheet naming. For example, for a project including buildings 202 and 204 the architectural demolition sheet should be named A‐101‐Bldg202 and A‐101‐bldg204.
Sheet File Composition Example:
‐ The Border Sheet is the G‐BS001 file. This file contains the title block and disclaimer with no referencing.
‐ The Enlarged Floor Plan background and structural columns A‐FP101 file.
The structural column plan is referenced into this file.
‐ The Plumbing Piping Plan represents the “working sheet” where new work is drawn, P‐PP101.
The Enlarged Floor Plan (architectural) is referenced into this file.
‐ The Sheet File is the final plot sheet, P‐101. This is where notes, titles, details, etc. are placed.
‐ The Plumbing Piping Plan and Border Sheet are referenced into this file.
