Jim shows an example of mechanical drawings for a construction project and explains that mechanical drawings may also be called heating, ventilation, and air conditioning drawings or HVAC drawings. These types of drawings are often created by a mechanical engineer and used by the HVAC contractor.
- [Instructor] In this video, we'll take a look at what…we call the mechanical drawings.…Now, the mechanical drawings, we can see here,…listed on our index sheet,…and mechanical drawings are typically designated…with an M in front of the sheet number.…And, these drawings generally refer to the set of drawings…that are going to give us information on a building's…heating, ventilation, and air conditioning systems.…These might also be called HVAC drawings,…or H-V-A-C drawings.…So, let's go ahead and use our hyperlinked index sheet,…and click,…and jump straight to the first mechanical drawing.…
Now, the first thing that you might notice when you look…at this first page in our mechanical drawings,…is that about two-thirds of the page is taken up by legends,…showing us what different symbols mean.…And, over here, there's this long list of abbreviations…that might be used throughout these drawings.…Remember, when this is printed out on paper,…this is 36 inches wide by 24 inches tall,…so there's a lot of abbreviations,…
In this course, learn how to read construction drawings. Jim Rogers helps you acquire this important skillset by taking you through the different components that make up construction plans, and helping you understand the language of construction drawings. He covers types of views, highlights different kinds of construction drawings—including architectural drawings, electrical drawings, and plumbing drawings—explains how to read general notes, and more.
