## Structures Design Office - Standard Drawings Preface PLEASE READ THE FOLLOWING BEFORE DOWNLOADING STANDARD DRAWINGS The “Drawings” in this document were produced with the use of Computer Aided Design and Drafting equipment, and depict common structural components or elements suitable for standardization. Whenever possible the drawings were developed to full completion and are ready for insertion in the Contract Documents. These fully developed drawings are referred to as “Standard Drawings” and are easily recognized by referring to their Index Numbers, which in this case consist of numerical symbols only. Besides fully developed “Standard Drawings”, this document also contains two (2) other types of drawings. The first type provides incomplete standard details and/or a table of variables that should be completed by the designer prior to inclusion of the drawing in the Contract Documents. These incomplete drawings are referred to as “Semi-Standard Drawings” and the letter “S” precedes their Index Numbers. The Index Numbers for the remaining drawings are preceded by the letter “I”. These drawings provide information or instructions to designers and should not be included in the Contract Documents. The Engineer of Record (EOR) for a “Standard Drawing” is already shown in the portion of the title block which has been executed. He/She will continue to be the EOR as long as the drawing(s) remain unaltered. The designer shall complete the remaining portion of the title block; however, completion of the title block is not deemed to be a drawing alteration. The Engineer of Record for a “Semi-Standard Drawing” is the Professional Engineer responsible for the completion of the drawing. In the event that a designer decides to alter the content of a “Standard Drawing” to suit a particular design, the designer may do one of the following: 1. Produce a new project specific drawing using the “Standard Drawing” as a guide. 2. Delete the name of the EOR and the Index Number, and modify the details/notes in the “Standard Drawing” as required. In this event, the “Standard Drawing” ceases to be a standard and the engineer responsible for the modifications to the “Standard Drawing” becomes the EOR for the modified Drawing. 3. If the required modifications are minor, show the modifications on a separate sheet. In this case cross-reference notes shall be provided on the “Standard Drawing” and on the sheet that shows the modifications, and “MOD.” (Modified) shall be added to the Index Number. It should be clearly understood that if modifications to the “Standard Drawings” are required, the work shall be performed under the direct supervision of a Professional Engineer, who then becomes responsible for the altered design. Again, it must be emphasized that “Standard Drawings” are sheets that require no further work and development. However, the subject treated by the standard might require additional drawings, prepared by the designer, which provide details necessary for construction and clearly convey the full extent of the proposed work. Some drawings include information for the designer that should be erased as instructed, before the drawings are incorporated in the set of construction plans.
