5 1. GENERAL INFORMATION 1.1 INTRODUCTION The Harris County Flood Control District 2016 CAD Standards Manual (Manual) provides a simple, intuitive guideline structured to effectively classify and organize data, yet provide flexibility to accommodate the specific needs of a project. Its purpose is to provide a consistent, uniform appearance when preparing construction drawings and exhibits. Occasional departure from this standard is anticipated, whether dictated by project condition or by outside agency requirement(s). The expectation is for the user to follow the guidelines proposed to the extent feasible in order to provide consistency in the final product. Departures from the standards of this Manual will require a prior written request for approval by HCFCD Project Manager. The influence of the U.S. National CAD Standard (NCS) is evident throughout this document although a majority of the specifications and requirements herein are simply reflections of our industry's local drawing and graphic standards. The NCS was created to encourage a more rational construction regulatory environment. The common language it proposes is a key component of Integrated Project Delivery, the collaborative union of people and practices to optimize project efficiency through all phases of design and construction. 1.2 REFERENCES This Manual is an updated version of the 1997 HCFCD Drawing and Graphic Standards Manual. The Harris County Flood Control District (HCFCD) has largely adopted applicable platforms of the U.S. National CAD Standards as the foundation of our CAD and graphic standards. The National CAD Standard is published by the National Institute of Building Sciences. For spatial data, HCFCD practices are based on local industry standards and current business requirements. The key element of this standardization is the requirement that all geospatial data and applications must be fully compatible with current ESRI or Autodesk geospatial products. CAD drafting and design software requirements are further described in Section IMPLEMENTATION This document is to be used for all new projects initiated with the District. For projects with the District that are already underway, coordinate with the District Project Manager to assess the appropriateness of implementation. It is not the 5

6 intent of this update to cause existing projects to incur additional time or cost, and measures should be taken to avoid such. Reference is made in Section 2.1 and 3.4 towards several additional files that will be made available to the consultants. These additional files are intended to make use of these standards easier, but several were not available at time of issuance of this document. The files will be made available at a future date. 2. PLAN REQUIREMENTS 2.1 HCFCD PROJECT PACKAGE 1. As a courtesy, consultants will be provided electronic media containing the appropriate data to assist in the preparation of the construction plans. Drawing, template, and standards files will be compatible with software versions currently used by the HCFCD. The following is a list of data included: a. A digital copy of the 2016 CAD Standards Manual. b. Digital drawing files (.DWG) of a standard border, completed cover sheet, abbreviation definition sheet, HCFCD standard details, general notes, and standard drawing blocks. c. A digital drawing template file (.DWT) compatible with AutoCAD. This drawing template will include basic layer definitions, dimension styles, and font styles. d. A digital drawing template file (.DWT) compatible with AutoCAD Civil 3D. This drawing template will include basic layer definitions, dimension styles, dimension styles and font styles. It will also contain some basic object and label style definitions for use with Civil 3D applications. e. A digital drawing standards file (.DWS). This drawing standards file shall be used by consultants to review project drawings for compliance with HCFCD drawing and graphic standards prior to submittal. f. The HCFCD standard color table plot file (HCFCD.CTB) for plotting B- sized 11 x17 sheets. g. The HCFCD standard linetype file (HCFCD.lin). h. Custom HCFCD logo (image). 6

7 2.2 PLAN SETS 1. Review and final copies of construction plans shall be produced to scale, appropriate on 11 x17 sheets in PDF and on bond or white Mylar as required per the consultant s contract. 2. Plan sets for typical HCFCD projects contain the following drawings compiled in the order below. A sample plan set is attached for your convenience. FIGURE SAMPLE PLAN SET Cover Sheet General Note Sheet Project Layout Drainage Area Map* Survey Control Map Plan and Profile Sheets Cross- Section Sheets SWPPP Sheets SWPPP Detail Sheets Structural/Misc. Detail Sheets HCFCD Detail Sheets Soil Borings* Note: Exact order to be coordinated with HCFCD Project Manager. * If required by the Project Manager. 2.3 SURVEY CONTROL 1. All survey information shall adhere to Harris County Flood Control District s current surveying standards. 2. All distances shown on the plans shall be surface distances. In the Drawing Notes, include the Project Scale Factor, which can be used to convert to State Plane grid coordinates. 3. Bearing orientation and horizontal grid coordinates are referenced to the Texas State Plane Coordinate System, South Central Zone, NAD 83, 1993 adjustment. 4. Elevation values are referenced to the North American Vertical Datum of 1988 (NAVD- 88), 2001 Adjustment. The Engineer shall coordinate the datum adjustment with the HCFCD Project Manager prior to the start of survey activities. 7

8 5. Project monumentation shall use HCFCD s Floodplain Reference Marks. Locations and data sheets for the monuments can be found at 8

9 2.4 GENERAL SHEET CONTENT 1. All drawings shall include a DATE STAMP that includes the plot date, the drawing path and filename. The date stamp shall be located outside the lower left corner of the drawing border and rotated to An example of this is as follows: 03/01/2016 G:\PROJECTS\123456\DRAWINGS\C- LAYOUT.DWG 2. Include signature blocks for HCFCD, utility companies, and other approving agencies as required. 3. Incorporate the HCFCD emblem within the border of each drawing. An electronic copy (image) of the emblem is available. Joint project drawings may include an image of the identification emblem or logo of each contributor including TSPE Firm Registration Number. (Do not display the image frame of the HCFCD emblem. Set the value of the AutoCAD IMAGEFRAME system variable to zero (0)). 4. Each construction drawing shall have the seal, signature and date of signature of the responsible Engineer in accordance with the Texas Engineering Practice Act and Rules. Use of an electronic seal is expected for providing the highest quality plan set submittal. Electronic sealing needs to be attached in accordance with the Texas Engineering Practice Act and Rules. 5. The project benchmark elevation, location, description, datum and datum adjustment are required on the Survey Control Map. Each plan and profile sheet shall contain benchmark and/or temporary benchmark information closely associated with the information on that sheet. See Section 2.3 Survey Control. 6. Store external reference files in the same folder as the project drawing files or in a subfolder labeled XREFS. 7. Use the Relative Path option to attach external reference files. 8. All externally referenced spatial data (DWG, DGN, PDF, images, etc.) shall be generated, where applicable, attached to the base drawing using coordinates 0,0,0 as the insertion point. 9

10 3. DRAWING STANDARDS 3.1 LAYERS The HCFCD layer standard is based on the drawing layer format promoted by the National CAD Standard (NCS). The NCS format consists of four data fields (Discipline Designator, Major Group, and two Minor Groups), plus a Status field. Each field is separated by a dash for clarity. The Discipline Designator and Major Group fields are mandatory. The Minor Groups and Status field are optional. C - A L G N - C H A N - A N N O - P Discipline Major Group Minor Group Minor Group Status Designator (4 letters) (4 letters) (4 letters) Field (1-2 letters) (1 letter) As a courtesy, HCFCD layer names, properties, and descriptions are defined in the HCFCD drawing template file (.dwt) provided in the project package. It is understood that additional layers other than those defined in the template may be necessary. User- defined layers shall be named using the NCS format and include a brief description prefixed with the category User Defined: making the layer easily identifiable as a non- standard layer and to assist in the review process. A drawing standard file (.dws) derived from the HCFCD drawing template is also included in the project package. Consultants shall use this file to review project drawings for compliance with HCFCD drawing and graphic standards and include the results of the review with the interim and final submittals. 10

11 3.2 LETTERING 1. TEXT HEIGHT Standard text height is 0.07 for most drawing annotation. A minimum height of 0.05 is acceptable when used for special purposes such as for symbols or stacked fractions, and existing text and/or dimensions. A minimum height of 0.03 is acceptable for special purposes such as survey spot elevations. 2. TEXT STYLES The Standard text style shall use the upper case Arial (arial.shx) font. Figure 3.2 can be used as a general text property guide.

State limits applicable to the typical section (based on CL or BL Sta.). 4. Detail indicators in plan view shall include the detail number and the sheet number reference. Detail number shall not be repeated in the plan set. 4. SUBMITTAL REQUIREMENTS 4.1 SOFTWARE AND DATA FORMATS 1. Data used in the design and production process must be submitted to assist in the project review. HCFCD S preference is AutoCAD Civil 3D. However, the use of other software able to convert files into a format compatible with 3D is acceptable. Large program projects may require AutoCAD Civil 3D to ensure compatibility throughout the program. Figure 4.1 is a sample of software and data formats commonly used in the civil industries. Tools other than those listed may be used, but it will be the consultant s responsibility to translate the files into a format compatible with tools employed by the HCFCD in the review process.
