10 Common Mistakes in Submission Drawings and How to Avoid Them

It is well known that submission drawings play a crucial role in obtaining building approval from local authorities. Even a minor error can lead to rejection, delays, or costly modifications. Whether you are an architect, a civil engineer, or an AutoCAD drafter, avoiding these common mistakes can save you time and significantly increase the likelihood of securing approval.

Let us delve into the details of the 10 most common mistakes found in submission drawings and explore practical ways to avoid them.

1. Incomplete Drawings Set

Mistake: Missing essential drawings like site plan, floor plan, elevation, or section.
Solution:
Always prepare a complete submission set including:

• Site Plan
• Floor Plans
• Elevations
• Sections
• Layout Plan

✔ Tip: Follow local authority checklist before submission.

2. Incorrect Scale Usage

Mistake: Using improper or inconsistent scales across drawings.
Solution:

• Use standard scales like 1:100, 1:50
• Maintain consistency in all drawings
• Clearly mention scale on each sheet

✔ Tip: Avoid “Not to Scale (NTS)” unless absolutely necessary.

3. Lack of Proper Dimensions

Mistake: Missing or incorrect dimensions.
Solution:

• Provide overall and internal dimensions
• Include plinth height, floor levels, and setbacks
• Use clear dimension styles

✔ Tip: Double-check dimension accuracy before plotting.

4. Ignoring Local Bye-Laws

Mistake: Not following building rules and regulations.
Solution:

• Check local development authority guidelines
• Verify setbacks, height restrictions, FAR, etc.

✔ Tip: Keep updated with the latest rules.

5. Poor Layer Management in AutoCAD

Mistake: All elements drawn in one layer.
Solution:
Use proper layer system:

• Wall
• Door/Window
• Text
• Dimension
• Electrical/Plumbing

✔ Tip: Assign colors and line weights for clarity.

6. Missing North Direction and Site Details

Mistake: Not showing north direction or site boundaries.
Solution:

• Always include north arrow
• Show plot boundaries and road access
• Mention adjacent properties

✔ Tip: Site plan should be clear and readable.

7. Improper Annotation and Text

Mistake: Small, unclear, or inconsistent text.
Solution:

• Use readable font size
• Maintain uniform text style
• Label all spaces properly

✔ Tip: Use standard abbreviations (e.g., WC, KIT, BED).

8. Inaccurate Section Drawings

Mistake: Sections not matching floor plans.
Solution:

• Ensure alignment between plan and section
• Show foundation, slab, beam, and roof details
• Include levels and heights

✔ Tip: Cross-check section line position in plan.

9. No Title Block or Project Information

Mistake: Missing essential project details.
Solution:
Include:

• Project name
• Client name
• Drawing title
• Scale
• Date
• Designer/Engineer details

✔ Tip: Use a professional title block template.

10. Poor Plotting and Presentation

Mistake: Low-quality prints or unclear line weights.
Solution:

• Use proper CTB/STB settings
• Maintain line thickness hierarchy
• Ensure clean and readable prints

✔ Tip: Always check a test print before final submission.
