1. PURPOSE AND SCOPE. This guidance establishes uniform drawing standards for Architect-Engineers (A-E), design-build contractors and Government personnel preparing design, engineering and construction documents, other than shop drawings. These standards are to facilitate preparation, review and a clear understanding of the contract documents.

2. REFERENCES:

2.1 ER 1110-345-700 Engineering and Design, Design

Analysis, Drawings and Specifications, Appendix C, Drawings.

2.2 A/E/C CADD Standards (current release). A copy of the

standards can be downloaded from the Internet at https://cadbim.usace.army.mil/CAD. The Albuquerque District has a Supplemental Standard to the A/E/C CADD Standards located at http://www.spa.usace.army.mil/Missions/EngineeringandConstructi on/CADStandards.aspx. This document will provide clarification and information not covered in the A/ E/C CADD Standard.

3. CADD OPERATING PROCEDURES. All original and finished drawings will be produced using Computer-Aided Design and Drafting (CADD). Existing hard copy data to be included in construction projects shall be scanned to raster format (minimum, vector preferred) and submitted with all required electronic files.

3.1 CADD Software. The basic software package used to create

contract drawings shall be Bently Inc.'s, MicroStation→ or Autodesk's AutoCad→, as specified by the supervising district. Manually drawn sketches may be used for schematic and preliminary studies.

3.2 CADD Standards. The A/E/C CADD Standards Manual was

developed by the CADD/BIM Technology Center to reduce redundant CADD standardization efforts within the Army, Navy, Air Force, and Corps of Engineers. The manual consolidates various CADD standards used in the Corps of Engineers into a generic format to operate under various CADD software packages (such as MicroStation and AutoCAD) and to incorporate existing industry and national standards.

VIII-2

3.3 Graphic Files.

3.3.1 Drawing CADD Files. Each graphic file should contain the contents of only one drawing (sequence numbered sheet). The architectural floor plan, site master plan, mechanical master plan, electrical master plan, etc., will each be constructed in a separate CADD file. These plans will not be split between two or more CADD files. Designers will use these floor plans/master plans as reference files and not copy them into their sheet design file. This will facilitate the incorporation of plan changes.

3.3.2 File Naming Convention. File names shall be as indicated in the A/E/C CADD standard, the Supplemental Standard and/or supervising district standard. The Architect-Engineer should obtain the file naming convention to be used for a particular contract from the district's project Technical Leader.

3.3.3 CADD Conventions. Architect-Engineer will use the CADD

level/layer convention, line symbologies, font libraries, and color tables as indicated in the A/E/C CADD standard or as required by the project’s supervising district. The Architect- Engineer should obtain the CADD conventions to be used for a particular contract from the district's project Technical Leader.

3.3.4 Drawing Size. Drawing sizes shall be as indicated in the A/E/C CADD standard and/or supervising district CADD standards.

Sketches or reduced size drawings for design brochures should be copying size 8-1/2"x 11" or 11"x17".

3.3.5 Title Blocks/Borders. Standard CADD title blocks and

border files for contract documents shall be obtained from the Albuquerque District web page at http://www.spa.usace.army.mil/Missions/EngineeringandConstructi on/CADStandards.aspx furnished to the A-E by the district project Technical Leader in the supervising district.

3.3.6 Units. Unless otherwise directed, drawings shall use the English System of Units. Additions/modifications to existing facilities may be done in the metric International System of Units (SI) to match the units used in the original facility construction if directed by the supervising district.

3.3.7 Scale. Appropriate scales shall be used to produce

clearly legible drawing and shall conform to the A/E/C CADD standard and/or supervising district. See paragraph 6.1 for conventional scale standards.

VIII-3

3.3.8 Numbering. Sheet numbers, sequence numbers, and CADD file names shall be as indicated in the A/E/C CADD standard, the Supplemental Standard and/or supervising district standards. All design submittals require sheet numbers. See paragraph 6.2 below. Final design and all subsequent design submittals also require sequence numbers. The CADD file name and plot date shall be shown on the border under the title block on all drawings.

3.3.9 Drawing Seals and Signatures. Architect-Engineer designed drawings should each be sealed, signed, and dated by the responsible designer. Electronic duplications of seals are acceptable. However, original, handwritten signatures on plotted record drawings are required.

3.3.10 Amendments to Drawings. Architect-Engineer shall make

amendment revisions to the most recent CADD drawings contents and title block. Unless other procedures established by the supervising district are furnished to the A-E, the A-E shall follow the procedures of the US Army Corp of Engineers Albuquerque District. These procedures can be obtained at http://www.spa.usace.army.mil/Missions/EngineeringandConstructio n/CADStandards.aspx.

3.3.11 Construction Modifications. The Architect-Engineer will be requested to make construction modifications by the district Technical Leader. Modifications will be posted using procedures similar to the amendment posting procedures described above.

These procedures can be obtained at http://www.spa.usace.army.mil/Missions/EngineeringandConstructi on/CADStandards.aspx.

3.3.12 Drawing Submittal Media. The supervising district shall establish the appropriate media and number of copies for submission of final drawings, and for other required submittals and include these requirements in the A-E Contract. These may be CADD files in .dgn or .dwg format, CAL files, CD-ROM with drawing files (and specifications), and full size or half-size hard copy drawings. If required by contract hard copy Vellum drawings, plotted from CAL files. Each submittal of CADD files shall contain an EXCEL spreadsheet containing the drawing number, sequence number, level/layer assignments, line colors, line weights, line types and any other workspace settings used for every drawing.

4. TYPES OF DRAWINGS

4.1 Budget Type Sketches/Drawings. Budget type

sketches/drawings are single-line diagrams for estimating costs and programming projects. These drawings are normally reduced for presentation in 8 1/2" x 11" Project http://www.spa.usace.army.mil/Missions/EngineeringandConstruction/CADStandards.aspx http://www.spa.usace.army.mil/Missions/EngineeringandConstruction/CADStandards.aspx

Functional data, controlling dimensions and gross area will be shown.

4.2 Site-Adapted Drawings. Site-adapted drawings are plans from a prior project. The level of implementation will be technically coordinated by district staffs. Typically site-adapted plans will be reviewed by each design discipline for updating to current criteria for the specific construction site. Site-adapted drawing title blocks shall be changed by deleting the original AE name and seal, replacing the project name with the current project name, deleting all amendment and modification notations and symbols throughout the drawing, and adding a note above the title block indicating the project from which the drawing has been site adapted.

4.3 Standard Drawings. Standard drawings are fully developed

plans and complete details for use in repeated locations or for site adaptation as follows:

4.3.1 Field Standards are District or local standards

derived from prior projects.

4.3.2 Regional Standards are Division or uniform criteria

standards established for regional, climatic and other environmental design conditions. Plates at the end of chapters in this AEIM are regional standards. Supervising districts may have additional standards. The AE should request a list of Standard Detail files available in MicroStation→ or AutoCad→ format, from the district project Technical Leader.

4.3.3 HQUSACE Standards are national standards. These documents which are to be utilized as completely as practicable for project design conditions. Analyses of foundations, structural and mechanical systems are normally authorized to site adapt the drawings. Revisions and deviations beyond these shall be reported and submitted for approval through the Technical Leader in the supervising district, to CESWD-ETEC-T to HQUSACE.

STRUCTURAL DRAFTING STANDARDS

STRUCTURAL DRAFTING STANDARDS

1.1 Drafting Standards. These structural drafting standards shall take precedence over all other referenced drafting standards in this criteria document to include the ERDC/ITL TR-01-6 - “A/E/C CADD Standard”.

1.1.1 Sheet Numbering. All sheet numbering shall comply with ERDC/ITL TR-01-6 – “A/E/C CADD Standard”, page 17, Figure 6 and Table 6. The “Discipline Designator”(Figure 6) shall be an “S” for ALL structural drawing sheets.

1.1.2 Reference Bubbles.

1.1.2.1 Structural Plans, Sections, and Details. All structural plans, sections, and details shall be identified with a reference bubble. The respective reference bubbles shall be referenced from structural notes, plans, or other sections and details. The number and lettering sequence shall start with number “1” and letter “A” on each respective drawing sheet.

1.1.2.2 Two-Part Reference bubbles. All reference bubbles shall be divided up into 2 parts.

1.1.2.2.1 Part One. Part one is the upper half of the bubble and is the reference number or letter of the bubble. Sections shall be numbers.

Details and plans shall be letters.

1.1.2.2.2 Part Two. Part two is the lower half of the bubble. When the bubble is shown on a section, detail or plan, part two is the number of the sheet where the section is drawn. When the bubble is on the sheet where the section, detail or plan is drawn part two is the number of the sheet where the detail was referenced from. In this case Part 2 could be numerous sheet numbers if the section, detail or plan is referenced at more than one location in the drawings. The text shall not be made smaller than 1/8” in height to fit into the two sections of the bubble. Break the lower bubble line to accommodate more than one sheet number.

1.1.3 Foundation and Framing Plan Dimensioning. All structural foundation and framing plans shall be FULLY dimensioned. No dimensions shall be referred back to the drawings of another discipline. Also, no dimensions shall be referenced back to a foundation plan from a framing plan or visa versa. All plans shall contain overall dimensions for the major parts of the building and the overall length of the building.

1.1.4 Grid Lines. All foundation and framing plans shall contain grid lines in both directions and on diagonals (if necessary for angular portions of the structure) for bearing and shear walls, beam and column lines, ribbed mat slab ribs, walls around stairs and elevators, pad footings and at all edges of the building. Each grid line shall be identified as to what element it locates with the use of keyed notes. Do not provide grid lines or location dimensioning for thickened slabs that would be provided under interior masonry partitions. All grid lines shall project from the grid line identification bubble to the element it is identifying.

1.1.5 Scale of Foundation and Framing Plans. All foundation and framing plans and overall building sections shall be drawing to a scale of at least 1/8”= 1’-0”.

1.1.6 Scale of Sections and Details. All foundation sections and details shall be drawn at a minimum scale of 3/4” = 1’-0”. All roof sections and details shall be drawn at a minimum scale of 1-1/2” = 1’-0”. The reason for these scale requirements is so the sections and details can be easily read when the drawings are plotted at one-half size.

1.1.7 Lettering. All lettering shall be uppercase and at least 1/8-inch in height when plotted at full size. This includes lettering contained within reference bubbles.

1.1.8 Standard Drawings. The drawings shall contain CESPA standard structural notes and typical details. These notes and details shall contain a list of the design loading criteria, a list of the strengths of the engineering materials used, the soil design property values, and any other data that would be pertinent to remodeling and/or future additions. These standard sheets are coordinated with the CESPA guide specifications such that conflicts between the two are minimized – reference the previous paragraph titled “Philosophy”. For electronic copies of these standard structural drawings go to web site http://www.spa.usace.army.mil/Missions/EngineeringandConstruction/CADStandards/Disciplines.aspx click on “Discipline Specific Requirements” and click on “Structural”. The contact for these drawings is Mr. Lance Faerber with the CESPA at 505-342- 3693, Fax 505-342-3497 or email at Lance.R.Faerber@usace.army.mil. These standard drawings are in MicroStation or AutoCAD format. The minimum requirements for the respective notes are described in detail throughout this document. These standard drawings are working files and can be revised by CESPA at anytime without notice.

1.1.8.1 Reference CESPA Standard Structural Drawing Sheets S001, S002, S003, S004 & S005 for required minimum standard structural notes and typical details. These five sheets shall be placed as the first five sheets of the structural drawings (no exceptions) no matter the size of the drawing sheets.

There are two sets of Sheets S001, S002, S003, S004 & S005, one for reinforced ribbed mat slabs (RRMS) and one for “Floating” or “Turned Down Edge” slab-on-ground foundation systems as noted on the respective drawings.

1.1.8.2 Standard sheets RM1, RM2 & RM3 are for RRMS foundation systems for use on layout of the ribs (sheet RM1) and typical foundation details (sheet RM2 and RM3).

1.1.8.3 Standard sheets RM4 & RM5 are for “Monolithic Floor Slab-On-Ground with Continuous Turned-Down-Edge Footings, Integral Interior Continuous Footings, and Integral Spread (Spot) Footings System” foundation system plans and typical details.

1.1.8.4 Standard sheets RM6 & RM7 are for “Housing Turned Down Edge” system foundation plans and typical details.

1.1.8.5 Standard sheet numbers with prefix “T” are standard foundation details for water and oil storage tanks.

1.1.8.6 Standard sheet numbers with prefix “HC” are standard sheets for precast concrete hollow core floor and roof planks.

1.1.9 Keyed Notes. Keyed notes are required for all referencing on the structural drawings except for the standard sheets S001, S002, S003, S004 and S005 that may or may not use keyed notes.

2. PREPARATION.

2.1 Size and Layout. The design analysis shall be produced by a word processor and letter quality printer (using 12 point size print), hand printed, or a combination thereof. All material shall be prepared on 216 X 279 mm (8-1/2 x 11 inch) standard sheet size.

Larger sheets, folded to the prescribed size, may be utilized when reduction is not feasible. All side margins will be 25 mm (one-inch) minimum to permit side binding and head-to-head duplication.

2.2 Organization. The design analysis for projects with more

than one building or facility will be organized into volumes for each major facility with a title page and complete table of contents for each volume. The several parts and sheets of the design analysis for each facility shall be numbered sequentially and bound under one cover (insofar as practicable) indicating the volume number (if more than one), the name of the facility, the name of the project if different, the project number, fiscal year, date of publication, and the drawing and specification numbers assigned to the facility. Covers will be a durable material with information to indicate contents thereon.

2.3 Classified Material. Every effort will be made to prepare the design analysis as to permit it to be an unclassified document, with proper reference to sources of classified material. Design analyses containing classified material will be marked and handled in accordance with applicable security regulations.

2.4 Design Calculations. Technical design analysis will be

performed and checked by separate individuals. An independent technical review shall be accomplished by registered architects, and/or engineers for completeness. The names or initials and registration of these individuals will be indicated on the computation pages or a cover sheet for the calculations.

Presentation will be clear and legible with a tabulation showing all design loads and conditions. The source of loading conditions, formulas, and references will be identified. Assumptions and conclusions will be explained and cross-referencing will be clear.

2.5 Automated Data Processing. When computer programs are used, the design analysis should include a complete listing of the input and output data, and calculations necessary for preparation of the input data. Input should be annotated to facilitate a reviewer's verification of data. Computer output should be in a format that identifies results by proper column headings and line identification keyed to a sketch of the structure if necessary.

Voluminous output data may be included in a separate volume or, subject to District approval, output presentation may be limited to key sections or to typical results when output is repetitive.

Results should be verified by an independent analysis, or example by a "ball park" hand analysis. The required level of verification is problem-dependent, including such factors as complexity of analysis, importance of results, and level of confidence in the program. Computer programs will be considered "approved" or "non-approved", where approval is granted by the appropriate District for A-E designs. Approved programs will be those commonly used programs judged to be reliable and thoroughly debugged;

examples of approved programs are BLAST, STRUDL and COGO. Non-approved programs are typically those written by an individual engineer to simplify repetitive computations. When non-approved programs are used the design analysis must include a description of the theories, assumptions and design methods employed, sufficient to verify validity of the program. Non-approved programs will require a higher degree of input description and output verification.

2.6 Standard Design. Analysis for standard designs shall be

prepared in accordance with the requirements of ER 1110-345-700 and applicable requirements in this chapter. Modifications of standard design analysis shall be accomplished to meet project site conditions as authorized by ER 1110-345-700.

2.7 Other Data. Codes, manuals, special investigations and

reports are to be considered and used as applicable.

2.8 Submission. Except when specifically exempted, the design analysis will accompany all drawings submitted for review, approval, information, or record, as outlined in ER 1110-345-700.

The design analysis presented with preliminary or partially completed work will be as complete as the stage of design progress permits. Required submittals of drawings, design analysis, cost estimate, and specifications are outlined in Chapter XI of this manual.

2.9 Government-Furnished Design. As subsequently explained, the Foundation and Pavement Design Analyses will be furnished by the District Geotechnical Branch.

3. FORMAT AND CONTENT. The basic format for the Air Force Project Definition, Army Project Engineering, Army Concept, Preliminary, Final, and Corrected Final Design Analysis is essentially the same, adjusted for the particular level of design and the type of facility. The following pages present the format to be used in the preparation of the Design Analysis for each discipline. While not all inclusive, Appendix B (DESIGN REQUIREMENTS AND PROVISIONS) of ER 1110-345-700 provides a checklist of items to be addressed in the Design Analysis.
