If you are planning to build a house, flat, shop, office, or factory, you may have heard the word PreDCR. For many people, this word feels confusing in the beginning. You may think about what PreDCR means, why it is needed, and how the approval process works. These questions are very common for anyone starting a construction project.

Today, most building approvals depend on building drawing online systems. Your drawings are checked digitally, not manually. If the drawings are not prepared correctly as per rules, approvals can get delayed or rejected. This can create stress, extra cost, and confusion, especially for first-time builders.

What Is PreDCR?

PreDCR stands for Pre-Development Control Regulations.

In simple words, PreDCR is a digital system used by government authorities to check building drawings before construction starts. The system ensures that your building plan follows all local rules and regulations.

Instead of checking drawings manually, the PreDCR software checks:

  • Plot size
  • Setbacks
  • Floor area
  • Height limits
  • Parking
  • Open spaces
  • Road width

If everything follows the rules, your plan moves forward for approval.

Why Is PreDCR Important?

PreDCR is important because it helps avoid problems later.

Here’s why PreDCR matters:

  • It reduces human errors
  • It saves time in approvals
  • It ensures your building is legal
  • It avoids rejection from authorities
  • It prevents future penalties or demolition issues

Without PreDCR approval, your building permission can get delayed or rejected.

Who Needs PreDCR Approval?

You need PreDCR approval if you are planning:

  • Residential building
  • Commercial complex
  • Industrial unit
  • Apartment or flat scheme
  • Villa or bungalow
  • Redevelopment project

Even small projects often require PreDCR drawings depending on local rules.

What Are PreDCR Drawings?

PreDCR drawings are special digital drawings prepared as per authority standards.

These drawings are not normal CAD drawings. They follow specific layers, colors, and naming rules so the PreDCR system can read them correctly.

At Kraty, we prepare drawings carefully, so they pass the PreDCR check on the first attempt.

Step-by-Step PreDCR Drawing & Approval Process

Let’s break the entire process into simple steps.

Step 1: Collect Basic Project Details

Before making any drawing, basic details are required:

  • Plot size and plot number
  • Location and city
  • Type of building (residential or commercial)
  • Number of floors
  • Client requirements

This step helps avoid mistakes later.

Step 2: Site Layout Planning

The site layout shows:

  • Plot boundaries
  • Road width
  • Building position
  • Open spaces
  • Entry and exit points

This is one of the most important parts of PreDCR drawings. Even a small mistake can cause rejection.

Step 3: Floor Plan Preparation

Floor plans are prepared for each level:

  • Ground floor
  • Upper floors
  • Basement (if any)
  • Parking floors

The plans include:

  • Room sizes
  • Wall thickness
  • Staircase
  • Lift
  • Toilets
  • Balconies

Kraty ensures every dimension follows local rules.

Step 4: Section and Elevation Drawings

These drawings show:

  • Building height
  • Floor-to-floor height
  • Total height from ground level
  • External look of the building

PreDCR software checks height limits strictly, so accuracy is very important.

Step 5: Convert Drawings to PreDCR Format

This is where many people face problems.

PreDCR drawings must follow:

  • Proper CAD layers
  • Correct naming
  • Fixed colors
  • Clean line work
  • No overlapping or broken lines

If this step is done incorrectly, the system will reject the file.

Using building drawing online services from Kraty helps avoid such technical issues.

Step 6: Upload Drawings to PreDCR Portal

Once drawings are ready, they are uploaded to the local authority portal.

The portal automatically:

  • Reads the drawings
  • Checks rules
  • Generates a report

This process usually takes a few minutes.

Step 7: PreDCR Report Generation

The PreDCR report shows:

  • Passed parameters
  • Failed parameters
  • Errors and warnings
  • Rule-wise calculations

If there are errors, drawings must be corrected and uploaded again.

Step 8: Correction and Resubmission (If Needed)

If the report shows issues:

  • Setback mismatch
  • Excess height
  • Parking shortfall

The drawings are corrected and resubmitted.

Kraty focuses on first-time approval, but corrections are part of the process in some cases.

Step 9: Final Approval by Authority

After PreDCR clearance, the file goes to:

  • Municipal corporation
  • Development authority
  • Local planning body

They review documents and grant final building permission.

Common Mistakes in PreDCR Drawings

Many approvals get delayed due to small mistakes.

Here are common errors:

  • Wrong layer naming
  • Missing dimensions
  • Incorrect setbacks
  • Height calculation errors
  • Parking misalignment
  • Non-standard CAD format

Choosing professional building drawing online services reduces these risks.

How Long Does PreDCR Approval Take?

Time depends on:

  • Project size
  • Drawing accuracy
  • Authority workload

On average:

  • Drawing preparation: 3–7 days
  • PreDCR checking: Same day
  • Final approval: 7–15 days

With correct drawings, the process is much faster.
