CONTRA COSTA WATER DISTRICT DRAWING PRODUCTION AND CADD MANUAL
SECTION 1 INTRODUCTION
1.0 INTRODUCTION
1.1 Purpose The purpose of this manual is to establish production standards for project drawing sets. These production standards are intended to ensure consistent electronic and hard copy deliverables (products) within the Contra Costa Water District (CCWD). All drawing sets and files prepared by or for the District, shall be in accordance with the standards set forth in this manual, with no exceptions. Deviation from these standards can only occur with the written permission of the Engineering Support Supervisor.
1.2 Scope This manual provides guidance and procedures for drawing sets prepared by the Contra Costa Water District (CCWD) or Consultants working on CCWD projects. The following sections of this manual address topics such as project folder setup and organization, sheet layout requirements, presentation graphics, layer-naming conventions, file naming conventions, and CCWD standard symbology. Appendices contain tables on layer names, color comparisons, as well as CADD symbology. This document assumes that CADD is the predominate method used to create drawing sets, whether by CCWD staff or consulting engineers. This document addresses the production of design drawing sets using CADD from the start of the project. While the drawing set is still the primary end product of a design done in CADD, the electronic files generated in the design process are becoming almost as important as the signed drawing set. This document attempts to address the digital CADD file formatting, the drawing set formatting, and the processes that tie the two together.
1.3 Responsibility The CADD instructions contained herein are for use on CCWD projects only. This manual is to be followed at all times, with no exceptions. Permission must be granted specifically from the Engineering Support Supervisor in writing to deviate from these guidelines.
1.4 Terms Drawing Set: The hard copy set of sheets documenting a project design. These are the printed design documents that when signed become the ‘record’ document. Drawing File (File): An electronic or digital computer file that is used to produce/print sheets and drawing sets. Drawing Sheet (Sheet): A single page of the drawing set.
1.5 Use and Implementation Consultants, who have a Consulting Agreement with the District to provide design services, shall be required to use these production standards on those design projects.

The implementation of these production standards will be instituted through the use of the accompanying CD described in Section 1.7 and provided by the District for use in preparation of CADD files for District use.
1.6 Availability to Consulting Engineers Consultants, who have a Consulting Agreement with the District to provide design services, shall be furnished a copy of the Drawing Production and CADD Manual. Request for the Drawing Production and CADD Manual shall be made to the Engineering Support Supervisor. All requests shall be made in writing and include the name of the project and the name of the District’s Project Manager or Project Engineer. One copy of the Drawing Production and CADD Manual shall be provided for each Consulting Agreement.
1.7 CCWD CADD Standard CD Accompanying the Drawing Production and CADD Manual is a CD including CADD files, line styles, fonts, and configurations that are required to complete drawings according to the format described in this manual. These files are to be used in AutoCAD 2004. The CD includes the following information: Templates: Used for establishing NEW drawings. The templates include pre-established
drawing layers, line types, dimension styles, text styles, preconfigured layouts, named page setups, symbols & details.
Title Sheet: Pre-established CCWD Title Sheet with predefined attributes. (ANSI A thru ANSI D)
Blocks: Pre-established CCWD drawing blocks. Details: Pre-established CCWD construction details. Scripts: Used for incorporating CCWD layers into existing drawings. Symbols: Used in Model and Paper space for general annotation. Plotting: Contains the required configuration files for plotting per CCWD standards. Layer: Provide explanations of layers by discipline or function group. (Based on the
current AIA layer convention)
1.8 Enforcement of CADD Standard During each submittal stage as outlined in Section 9, the consultant is required to submit a full submittal package with all electronic CADD files on a CD to the Engineering Support Supervisor. The Engineering Support Supervisor will check for conformance with the District’s CADD standards as specified in this manual and the District’s template file. CADD files and drawings that do not conform to the standards outlined in this manual shall not be accepted. It is the responsibility of the Consultant to follow all guidelines set forth in this CADD Manual. The Consultant shall bear all cost necessary to correct any part of the submittal that does not conform to the standards.

SECTION 2 PROJECT SETUP & FILE NAMING
EFFECTIVE DATE: 5/01/2004 PAGE 2-1
2.0 PROJECT SETUP & FILE NAMING 2.1 Project Specific Standards This standard is to be followed at all times, however CCWD recognizes the need to be more specific in some instances. If the project manager deems it necessary to be more specific or deviate from these standards they shall make a written request to the Engineering Support Supervisor prior to making the change. All change requests shall be documented in an ASCII text file named ‘CADD Standard Changes.txt’. This file shall be located in the root folder of the project. Permission must be granted specifically from the Engineering Support Supervisor in writing to deviate from these guidelines. 2.2 File Format The District uses AutoCAD Map 2004 to create and modify all maps and engineering drawings. Consultants who produce drawings for the District shall produce files that are compatible with the version of software currently in use at the District. All drawings produced for the District shall be in AutoCAD 2004 format or the latest available version. Prior to beginning work on a project, the Consultant shall verify with the Engineering Support Supervisor the current software version. 2.3 Folder Structure The District’s electronic files are stored in designated project folders. This project folder is typically given a unique District project number and project name. It is required that all electronic drawing files related to a specific project such as working drawings and external reference files shall reside in a single sub-folder. See Section 2.8, Tracking Drawing Revisions for more information on revision sub-folders. CCWD Blocks and symbols shall reside in a separate directory for filing purposes.
Figure 2.1: Project file structure
2.4 Use and Storage of External Reference Files (XREFs) and Raster Images The use of external reference files (XREFs) and raster images is required by CCWD. All externally referenced files and raster images shall be located under the main project folder or in one of its sub- folders. See Section 4 for more detail on xrefs and raster images.

2.5 Drawing File Types – General CCWD is separating the design and plotting processes based on two file types, Working and Sheet drawing files. Working drawings are files considered as “work in progress”. They contain the physical design components of the project (e.g., piping, grading, and improvements). Working drawings shall be drawn at full scale in the model space. Working drawings shall not contain any sheet layouts. Sheet files are scale based, they typically divide a project site up based on what fits on a sheet at a particular scale. Sheet files are the final project sheets that are ready to be plotted. A sheet drawing is an assembly of externally referenced model files plus additional sheet-specific information (e.g., north arrow, scales, scales, section cuts, and title block information). These files are to be used for plotting only; design information will be not acceptable in these files. Sheet files will contain only one layout. The layout name will be the same as the sheet file name. This will ensure a 1:1 correlation between the digital file and hard copy sheet.
2.6 Working File Naming This section covers design file naming. Working or design files are site based and should include the entire project in one file. These files are typically segregated based on design discipline or type of information; such as base, proposed, demolition or civil. Design files shall be named in the following way: • Project Number-Modifier-Revision Indicator • i.e.; 100150-Civil.dwg or 100150-Base.dwg The modifier could be equal to the design discipline. See Section 6 for more information on layer modifiers.
2.7 Sheet File Naming Sheet drawing file names must be associated with the actual drawing number. File names should be unique. Never reuse a file name. Sheet files will have only one layout. The following procedures have been established for creating drawing names and drawing numbers. The Engineering Support Supervisor shall provide the specific drawing numbers to be used for all District drawings. All drawing CADD file names shall follow these procedures: Example: DXXXXXRX.dwg “D” is letter code, indicating the drawing size. These codes may include: D = 22” x 34” B = 11” x 17” A = 8 ½” x 11” Following “D” (“XXXXX”) is a five digit drawing number, assigned by Engineering Support Supervisor at the request of the Project Manager or Project Engineer.

“R“ stands for Revision and shall be followed by a letter or number reflecting the revision number. The file name shall be included in the title block of all sheets generated from it. Typical examples of a drawing number and CADD file name: Drawing Number Revision Indicator CADD file D-01234 R0 D01234R0.dwg
Figure 2.2: Naming convention for AutoCAD drawings All drawings submitted to CCWD must be in the sheet drawing or the final “READY-TO-PLOT” format.
2.8 Tracking Drawing Revisions The term “Drawing Revision” refers to modifications that are made to a drawing set or sheet throughout the design review process and after it has been signed and issued. Sheet file name extensions indicate the current drawing file revision. During the design process, revision extensions are indicated with a letter. The initial issue of a sheet drawing file has a file name extension of D01234RA. Subsequent drawing file revisions have sheet file name extensions of D01234RB, D01234RC, etc. This continues until the design review process is complete and the set is issued for bid. Once a drawing set has been signed and issued for bid, the file name extension changes to a number starting with R0, i.e. the sheet file name is now D01234R0. The corresponding CADD design file becomes a record document. As such, it should not be modified in any way. Design revisions affect the entire drawing set, even if only a single sheet is modified. Because of this, all of the drawing files in a project will be incremented when a revision is made. This will be accomplished through the use of sub-folders for drawing file storage as well as renaming the sheet drawing file. When a revision to a CADD drawing is required, use the following procedures: • Copy the previous revision sub-folder and rename it with the next revision indicator. • Rename ALL the sheet drawing files with the next revision extension number. The actual file
name remains the same, only the revision extension changes. The working drawing files do not get renamed. See figure 2.3.
• Bubble all drawing revisions on the appropriate layer, using a leader and the block symbol for each revision.

3.0 DRAWING SET GUIDELINES & SHEET CONTENT REQUIREMENTS
This section provides guidelines for the preparation of sheets produced for various disciplines and needs. This section also provides general guidelines to complete design drawings to meet CCWD’s general drawing presentation criteria. These guidelines must be followed at all times to achieve consistency, uniformity, accuracy and neatness for all CCWD projects. These guidelines also enhance the efficiency of the drafting effort for all projects. The list of sheets for each type of project and/or discipline generally encompass all sheet requirements in support of the final design, procurement, fabrication, installation and tests applicable to that project or discipline. This section also covers standard CCWD operating sheets.
3.1 CCWD Drawings Sets Types of CCWD drawing sets include: Applicant Treated Water Infrastructure Base Map Calgrid Site Facility Maps Canal Maps
3.2 Project Drawing Sets Multiple sheet types can be combined into single sheets for smaller projects. However, any project should contain sufficient drawing space to make reading and use of sheets simple. All projects must have a cover sheet whereas some projects will not have discipline sheets.
3.3 Sheet Sequence Drawing sets shall be arranged in a logical manner in order to minimize confusion. The following sequence provides a general guideline of the drawing sheet order. When demolition sheets are needed, always start with a specific discipline as cited below. Deviation from this procedure shall require prior approval from the Engineering Support Supervisor.
1. General Sheets 2. Civil Sheets 3. Architectural Sheets 4. Structural Sheets 5. Mechanical Sheets 6. HVAC Sheets 7. Electrical Sheets 8. Corrosion Control Sheets
3.4 Sheet Layout Requirements Sheets generally depict structures, walls, partitions, layouts, foundation, mechanical equipment ducts, pipes, roads, and conveyances, etc. Regardless of the discipline, CCWD’s standard practice and standard industry practice shall be used in the development of all sheets and drawing sets.

Sheets that depict elements along a main line shall be oriented so that stationing progresses from left to right across the sheet. Sheets depicting any other elements shall be oriented so that the north is toward the top or toward the left-hand side of the sheet. A key plan shall be located in the upper right corner, when required. When a complete plan or elevation cannot be shown on any one sheet, a match line (see line type table, section 5.4 for appropriate symbol) must be used for continuation to the next sheet. An alpha character shall be used to identify the match line and a sheet number shall be used to identify the sheet on which the drawing is continued. In order to provide clear interpretation, a sheet that requires reference to another sheet or data, shall be adequately cross-referenced to that sheet. References to other sheets shall be made to sheet numbers only. The space immediately above the right side of the title block shall remain blank for future annotations, i.e., “Reduced Size", "Check Print", etc. Plan views shall be oriented so that the north is toward the top of the sheet or within the first and fourth quadrant, when it is not in conflict with other criteria. In any event, all plan views in a set shall be oriented in the same direction. An example of the preferred general layout for projects is shown on Appendix A3-4.
3.5 Drawing Sizes Standard drawing sizes shall conform to ANSI standard Y14.1-1975. CCWD’s official project drawing size is “D”, 22” X 34”. Any deviation from this drawing size will need prior approval from the Engineering Support Supervisor.
3.6 Drawing Borders and Title Blocks The standard District drawing border measures 22”x34” at the cut lines. This standard sized drawing border shall be used for all projects, unless the contract specifically authorizes a different drawing size. The drawing border can be found in the “CCWD CADD\Title Sheet” folder. All borders shall be inserted in paper space at full scale and insertion point of 0,0. Borders that are attached as reference files are not acceptable. See Sections 3 and 4 on Borders and Drawing Scales for information. The title block contains attribute fields that set the correct text size, weight, font, and layer for all title block entries. These attribute fields shall be used when adding drawing information to the title block. The Consultant’s drawing border contains an empty box at the lower margin that is reserved for the Consultant’s logo.
3.7 Drawing Borders Standard borders shall be used on all drawings prepared by or for CCWD. Cited below is a list of all standard drawing borders:
