NCR and SOR

Difference Between NCR and SOR in Construction Projects

In construction projects, maintaining quality and compliance is key. Two important tools to achieve this are NCR (Non-Conformance Report) and SOR (Site Observation Report). While both address site-related issues, they differ in purpose and approach:

1. NCR (Non-Conformance Report)

• Purpose: Issued when work or materials fail to meet project specifications, standards, or approved designs.

• Focus: Reacts to non-compliance issues that require corrective action.

• Impact: Aims to rectify errors and prevent delays or rework.

• Examples:

• Incorrect materials used.

• Work deviating from approved drawings.

2. SOR (Site Observation Report)

• Purpose: Documents observations of potential risks or areas for improvement on-site.

• Focus: Proactive tool to highlight minor issues before they escalate.

• Impact: Promotes safety, efficiency, and quality awareness.

• Examples:

• Minor safety hazards.

• Early signs of defects.

Key Difference:

• NCR is corrective, addressing non-conformities after they occur.

• SOR is preventive, aiming to identify and resolve issues early.

Both are critical in ensuring quality control and continuous improvement in construction projects.
