Modeled on the Historic American Buildings Survey (HABS), founded in 1933, HAER set out with historians, architects, engineers, and photographers to capture vanishing industrial and engineering treasures in rural and urban areas nationwide. In 1986, the American Society of Civil Engineers was joined by the American Society of Mechanical Engineers (ASME), the American Institute of Mining and Metallurgical Engineers (AIMME), and the Institute of Electric and Electronic Engineers (IEEE) as signatories to HAER’s mission.  \nHAER documentation comes from three sources. The HAER Washington office produces documentation internally and with field teams (made up primarily of students) working all over the country, generally for twelve-week terms in the summer. HAER also receives documentation from federal and state agencies that are required to mitigate any adverse impacts of federal actions under sections 106 and 110 of the National Historic Preservation Act. . Those preparing mitigation documentation should contact the appropriate regional National Park Service office (a list is provided on our website) or HAER Washington staff for review of drawings and to answer any questions. HAER also accepts donated documentation from interested members of the public. The HAER Washington office will assist people producing documentation in meeting these requirements for transmittal to the Library of Congress. Completed HAER projects are archived in the Prints and Photographs Division at the Library of Congress and are available in electronic format from the Library’s website: [http://www.loc.gov/pictures/collection/hh/](http://www.loc.gov/pictures/collection/hh/) .  \nThis manual is an update of","cbCaiqqzI66T8r7S","https://ap.wps.com/l/cbCaiqqzI66T8r7S","pdf",870854,27,"English","# Introduction\n# Role of the Recorder\n## Team Work\n## Identification and Recordation\n# Survey Process\n## Planning\n### Determining Scope\n### Considering the Relative Significance of the Site\n### Physical Condition\n### Integrity\n### Budgeting Time\n## Research\n## Field Records\n### Preparing Field Notes\n### Field Photography\n### Other Field Notes\n## Tools for Measurement in the Field\n## Methods for Measurement in the Field\n### Reference Planes (Datum Lines)\n### Additive vs. Running Measurements\n### Tolerances\n### Writing Dimensions\n### Other Measuring Techniques\n### How to Measure Diameters\n### How to Measure Site Plans\n### How to Measure Buildings\n### How to Measure Bridges\n### How to Measure Machines\n### How to Interpret Industrial Processes\n# HAER Drawing Format\n## Graphic Standards\n### Drawing Sizes\n### Materials for Final Submission\n### Scale\n### North Arrow\n### Sheet Layout\n### Electronic File Sizes/Standards and File Formats\n### Suggested Symbols\n### Legend\n### Locator Diagram\n### Hatch Patterns\n### Screening\n### Stipple and Shadow\n## Methods for Recording Drawings\n### Existing Information\n### Hand Drawing\n### Line Weights\n### Digital Recordation\n### Interpretive Drawings and Thumbnail Sketches\n## Types of Graphic Representation\n### Title Sheet\n### Existing Conditions Plan\n### Site Survey/Topographic Plan\n### Section\n### Elevation\n### Detail\n### Site Perspective\n### Axonometric\n### Isometric\n### Cutaway or Exploded View\n# Computer Aided Drafting and Design Recordation (CAD)\n## Archival Media\n## Plotter Requirements\n## Text\n## Line Weights\n## Layer Naming Standards","[{\"question\":\"What is the purpose of the HAER Drawing Guidelines manual?\",\"answer\":\"The manual guides the creation of existing-conditions graphic documentation for industrial and engineering resources that meets HAER standards.
