Jim explains that construction drawings are often created by many different professionals—including the architect and various engineers—and sometimes the different drawings contain conflicting information. Jim discusses the importance of getting clarifications before building starts.
- Well, at this point we've really gone through all of the plan-reading basics. We learned about the different types of drawings, and views. And we talked a lot about cross-referencing all of these views, and details, and schedules, and other information to get a picture of how things are supposed to be built, and what the structure's really supposed to look like when we're done. And we also talked a little bit about moving between the plan notes, and the project specifications. Now, this is a great deal of information.
It's spread out across many, many pages, and it's oftentimes developed by several different consultants, or companies, and we've seen that throughout the course. This makes the potential for mistakes somewhat high, and I really can't tell you how many construction projects have been compromised at some stage due to conflicting information in these construction documents. When things don't fit, or notes and details conflict as you move from one drawing to the next, you need to get clarification.
I really can't overemphasize that point. Get clarification from the designer. And I would really always recommend getting that clarification in writing, but that's probably a topic for a different class. My point here is that I don't want you to be surprised if the drawings aren't perfect. In fact, there's so much information, and so many parts and pieces that I'm generally surprised if the drawings are perfect. Do your best to pull all of the information together from all of the various drawings, views, details, and schedules, and then, don't be afraid to ask if you still need more information.
Many of these drawings are highly technical, and the fact that the styles can vary widely from one designer to the next, really can make it hard to read construction drawings sometimes, but the worst thing that you can do is not ask for help, or clarification. It's much easier, and much cheaper, to get clarification before you build than it is to tear something down, and start over, because it got built and doesn't meet the designer's intent.
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.
