What are Technical Drawings?

Technical drawings are detailed illustrations that outline the specifications of a construction project, including measurements, materials, and design features.

Explain the purpose of technical drawings and their importance in communicating construction plans.

Types of Technical Drawings

There are several different types of technical drawings, including floor plans, elevations, sections, and details.

Provide an overview of the different types of technical drawings and their uses in construction projects.

Reading Floor Plans

Floor plans are drawings that show the layout of a building from a top-down perspective. They include details such as room dimensions, wall locations, and door and window placements.

Demonstrate how to read and interpret a floor plan, and provide examples of common symbols and notations.

Understanding Elevations

Elevations are drawings that show the exterior of a building from different angles. They include details such as rooflines, window and door styles, and exterior finishes.

Explain how to interpret elevations and how they can be used in the construction process.

Using Sections

Sections are drawings that show a cutaway view of a building, revealing details such as interior walls, stairs, and structural elements.

Demonstrate how to read and interpret sections, and provide examples of common symbols and notations.

Examining Details

Details are drawings that show specific construction elements in close-up detail, such as staircases, windows, and doors.

Explain how to read and interpret details and how they can be used in the construction process.

Review and Practice

Now that you understand technical drawings in construction, it's time to practice! Review different technical drawings and identify key features and notations.

Provide examples of technical drawings for students to review and practice identifying key features.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
