Jim discusses the information that appears in construction plans versus information contained in construction specifications. Spec books contain information to supplement construction drawings.
- In this course, we're really going to focus on how to read construction drawings, but I do want to spend a few minutes discussing one very important item that I think you need to be aware of when it comes to reading and interpreting these drawings. That is, I do want you to recognize that the term construction documents really can comprise more than just the drawings. For example, many projects will also utilize a set of specifications. Now this is a set of specifications from a commercial construction project.
And you can see that there's a lot of information in here. This information is generally presented as printed instructions that supplement the information over in the drawings. And this is usually divided into many different sections that will include headings like electrical, paint, flooring, decorative concrete, and so on. Now this document is generally produced by or at least under the guidance of the same designer that oversaw the production of our constructions drawings.
And it'll contain information like descriptions, model numbers, or even brand names that give the builder more detailed instructions on the products that the designer wants used. So, for example, our construction drawings contain the basic on the windows that are going to be installed when this house is built in our sample project. Now, these drawings are going to show us precisely where these windows go, what size they are, and how they're connected to the rest of the structure.
But I may need to consult the specification book for this project to find out things like the minimum energy rating required for these windows on this project. Now one of the tricks here is to make sure that you consult both the drawings and the specifications to make sure that you have all of the information that you need to build. Now keep in mind, that this broader term construction documents might also include some more things. Things like the construction contract and maybe some additional drawings known as shop drawings, or assembly drawings.
Again, these are just some of the documents that might provide some additional details as to what the owner and the designer expect you to build out in the field. So make sure to keep this all in mind and remember that the construction drawings that are really the focus of this course, they might be only one of the documents that makes up our entire list of, what are collectively referred to, as construction documents. So one last tip. I want you to make sure that you also keep in mind that when you do have several sets of documents that might have been produced by different people, sometimes they can contain conflicting information.
So back to my window example, if the drawings have a note with the required energy rating for the windows, and the project specification book has a different note about the same window, you better get some clarification before you start ordering materials, or better yet, before you give that customer a price.
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.
