Reading construction documentation – correct interpretation of technical and construction drawings

icon

Training process

Training needs analysis

If you have specific requirements regarding the training programme, we will carry out a training needs analysis for you. This will guide us on which aspects of the programme should receive greater emphasis, so that the training programme meets your specific needs.

What will you gain?

icon

Navigate drawings efficiently - You will quickly locate key information in construction drawings, including title blocks, revision tables, notes, and specifications, so you can review documentation faster and with more confidence.

icon

Understand drawing structure - You will learn how a technical drawing is organized and how to read field layouts, markings, and letter-number references, helping you work more confidently with project documentation.

icon

Read formats and dimensions - You will understand sheet formats and dimensions shown on drawings, making it easier to assess whether documentation is complete and reducing mistakes when interpreting the scope of work.

icon

Interpret line types correctly - You will learn to distinguish continuous, dashed, dotted, chain, wavy, and zigzag lines, so you can correctly read what is visible, hidden, auxiliary, or shown by convention on a drawing.

icon

Understand projection methods - You will see the differences between European and American projection methods, helping you avoid mistakes when reading views and understand faster how an object is presented on a drawing.

icon

Read dimensions accurately - You will master dimensioning elements such as dimension lines, extension lines, dimension values, and symbols, allowing you to read the data needed for execution or inspection with precision.

icon

Reduce interpretation errors - You will understand the basics of tolerancing and the meaning of drawing markings, so you can spot potential inconsistencies earlier and reduce the risk of costly mistakes during project execution.

icon

Analyze documentation on your own - After the training, you will be able to review construction documentation independently in terms of layout, markings, line types, and dimensions, making teamwork with designers and contractors easier.

Training programme

1. Introduction to construction documentation

2. Structure of a technical drawing

  • information table,
  • revision table,
  • table with BOM,
  • notes,
  • specifications,
  • location defined by letters and numbers.

3. Dimensions and application of formats

4. Types of lines

  • continuous,
  • dashed,
  • dotted,
  • double-dotted,
  • wavy,
  • zigzag.

5. Application of lines

6. American and European projection – differences

7. Borders and drawing title blocks – reading

8. Elements of dimensioning

  • dimension line,
  • extension line,
  • dimension figure,
  • leader line,
  • reference line,
  • dimension symbol.

9. Basics of tolerating

10. Training summary

What are the prerequisites for participating in the training?

icon

Basic technical awareness - You should be comfortable with basic technical and construction terms so you can connect drawing markings with building elements and the scope of work more easily.

icon

Ability to work with documents - You should be able to read and compare documents carefully, because during the training you will analyze markings, notes, tables, and the links between them.

icon

Basic geometry knowledge - You should know basic geometric concepts such as dimensions, axes, directions, and views so you can understand how elements are represented on a drawing.

icon

Attention to detail - You should be ready to analyze details and markings carefully, because the training requires focus on line types, dimensions, tables, and differences between projections.
