Lane Closure Taper Setup Verification Checklist Dubai
The taper is the transition zone where drivers move from the closing lane into the open lane. A well-installed taper should match the approved traffic-management arrangement and provide a clear, continuous path for approaching traffic.
HMJ Contracting supports lane closure safety in Dubai with signs, TMA vehicles, barriers and work-zone equipment.
1. Confirm the Approved Layout
Use the latest traffic-management drawing before installation.
2. Mark the Taper Start and End
Confirm the physical limits before placing cones or delineators.
3. Check Cone or Delineator Alignment
The taper should form a clear and continuous line without sudden gaps or irregular offsets.
4. Review Spacing
Confirm spacing matches the approved arrangement or project requirements.
5. Verify Merge Direction
Drivers should clearly understand which lane remains open.
6. Check Arrow Board Position
Where used, the arrow board should reinforce the correct merge direction and remain visible on approach.
7. Review Advance Warning Signs
The taper should not be treated as ready until the upstream warning sequence is complete.
8. Check TMA and Protection Position
Where TMA protection is required, confirm its location relative to the work area and taper.
9. Inspect at Night
For night work, confirm cone reflectivity, warning lights and arrow-board visibility.
10. Complete a Final Drive-Through
Review the closure from the road-user perspective before opening the work zone.
A structured taper check reduces confusion and helps the site team identify setup errors before traffic reaches the closure.
