Snagging lists are a critical tool in construction project management, yet they're often misunderstood or poorly executed. This guide explains what snagging lists are, why they matter, and how to use them effectively.

What Is a Snagging List?

A snagging list (also called a punch list or defects list) is a document that identifies defects, incomplete items, or quality issues that need to be addressed before final handover of a construction project.

Purpose of Snagging Lists

Snagging lists serve several important purposes:

  1. Quality Assurance: Ensures work meets agreed standards
  2. Documentation: Creates a clear record of outstanding items
  3. Communication: Provides clear instructions to contractors
  4. Accountability: Tracks responsibility for rectification
  5. Handover Preparation: Ensures space is ready for occupation

When Are Snagging Lists Created?

Snagging typically occurs at specific project stages:

Practical Completion Stage

The main snagging inspection usually happens when works are substantially complete but before final handover. This is the most critical snagging stage.

Interim Inspections

Some projects have interim snagging inspections at key milestones to catch issues early.

Post-Occupation Snagging

Defects may be identified after occupation, particularly those only visible in use (e.g., heating performance, drainage issues).

What Should a Snagging List Include?

An effective snagging list contains specific, actionable information:

Essential Information

Each snagging item should include:

  • Location: Specific room and position
  • Description: Clear description of the defect
  • Trade: Which trade is responsible
  • Priority: Critical, important, or minor
  • Photograph: Visual evidence where helpful
  • Reference: Drawing or specification reference if applicable

Example Entries

Good snagging entry: "Bedroom 2, north wall: Paint scuff 1.2m from door frame, 1.5m from floor. Requires touch-up. (Photo ref: IMG_123)"

Poor snagging entry: "Paint touch-up needed"

The first entry is specific and actionable. The second is vague and unhelpful.

Common Snagging Items

Typical snagging issues include:

Decorating

  • Paint scuffs, marks, or poor coverage
  • Uneven paint lines at edges
  • Visible filler or preparation marks
  • Splashes on adjacent surfaces

Carpentry

  • Door alignment and operation
  • Gaps in architrave or skirting
  • Rough or unfinished edges
  • Ironmongery loose or misaligned

Flooring

  • Scratches or damage
  • Gaps at edges or transitions
  • Uneven surfaces
  • Transition strips missing or poorly fitted

Plumbing

  • Leaks or drips
  • Poor silicone sealing
  • Fixtures loose or misaligned
  • Water pressure issues

Electrical

  • Faceplates crooked or damaged
  • Switches or sockets not working
  • Light fittings loose or incomplete
  • Visible cables or poor finishing

General

  • Cleaning required
  • Debris or waste not removed
  • Protective coverings not removed
  • Damage to completed works

Who Creates the Snagging List?

Different parties may be involved:

Client or Client Representative

Often creates the primary snagging list, representing the client's quality expectations.

Project Manager or Clerk of Works

May conduct snagging inspections on behalf of the client.

Main Contractor

Often conducts pre-snagging to identify and rectify issues before client inspection.

Independent Snagging Surveyor

Some clients engage specialist snagging surveyors for thorough independent inspection.

How to Conduct an Effective Snagging Inspection

Follow a systematic approach:

Preparation

  • Schedule inspection at appropriate stage
  • Ensure good lighting available
  • Bring camera, notepad, and measuring tools
  • Have drawings and specifications to hand
  • Allow sufficient time (don't rush)

Systematic Approach

  • Work room by room
  • Follow a consistent pattern (e.g., clockwise from door)
  • Check walls, ceilings, floors, fixtures
  • Test all operable items (doors, windows, switches)
  • Look from multiple angles and distances

Documentation

  • Photograph all defects
  • Note exact locations
  • Be specific in descriptions
  • Number items for easy reference
  • Categorise by trade or priority

Managing the Snagging Process

Once the list is created, effective management is essential:

Distribution

  • Share list promptly with contractor
  • Ensure all relevant parties have copies
  • Clarify any ambiguous items
  • Agree rectification programme

Tracking

  • Monitor progress on rectification
  • Update list as items completed
  • Conduct re-inspection
  • Document completion with photographs

Re-Snagging

  • Inspect rectified items
  • Identify any new issues caused during rectification
  • Ensure quality of repairs matches original work
  • Sign off completed items

Common Snagging Challenges

Be aware of typical issues:

Disagreement on Standards

What one party considers a defect, another may see as acceptable. Reference specifications and industry standards to resolve disputes.

Incomplete Rectification

Items marked as complete may not meet standards. Always re-inspect before sign-off.

New Damage During Rectification

Trades returning to rectify items may cause new damage. Protect completed works and inspect after rectification.

Time Pressure

Pressure to handover can lead to incomplete snagging. Maintain quality standards despite time constraints.

Snagging in Different Project Types

Approaches vary by project type:

New Build Residential

Typically comprehensive snagging at practical completion, with defects period for post-occupation issues.

Refurbishment

May have phased snagging as areas complete, particularly in occupied buildings.

Commercial Fit-Out

Often tight handover deadlines require efficient snagging process and rapid rectification.

Best Practices

Follow these principles for effective snagging:

  1. Be Thorough: Better to over-document than miss items
  2. Be Specific: Vague descriptions lead to disputes
  3. Be Fair: Distinguish between defects and design choices
  4. Be Timely: Conduct snagging at the right stage
  5. Be Systematic: Follow a consistent approach
  6. Be Professional: Focus on facts, not opinions

Conclusion

Snagging lists are essential for ensuring construction projects meet quality standards before handover. An effective snagging process requires systematic inspection, clear documentation, and professional management of rectification.

Whether you're a client, contractor, or project manager, understanding and implementing proper snagging procedures ensures better outcomes and smoother handovers.
