create a checklist of columns inspection according to SBC

Preparation

Review the SBC guidelines and specific project specifications for column inspections.

Assemble all necessary tools: measuring tape, calipers, inspection camera, etc.

Ensure personal protective equipment (PPE) is worn by all personnel involved in the inspection.

Visual Inspection

Examine the column for visible surface defects: cracks, chips, or spalling.

Inspect for signs of rust or corrosion on exposed reinforcement.

Verify that the column is plumb and properly aligned according to design.

Steel Reinforcement Inspection

Confirm the size and grade of main steel bars

Check bar diameter: _____ (specify size)

Verify bar grade: _____ (specify grade)

Inspect the spacing and placement of stirrups

Measure stirrup size: _____ (specify size)

Confirm spacing between stirrups: _____ (specify spacing)

Check for dowels and their placement

Verify dowel size and length: _____ (specify size)

Confirm dowel embedment depth: _____ (specify depth)

Inspect any splices in the reinforcement

Check splice length: _____ (specify length)

Ensure proper overlap and bonding of spliced bars.

Certainly! Here’s an expanded checklist for the Steel Reinforcement Inspection section, incorporating additional steps for thoroughness

### Steel Reinforcement Inspection

Confirm the size and grade of main steel bars

Check bar diameter: _____ (specify size)

Verify bar grade: _____ (specify grade)

Inspect the spacing and placement of stirrups

Measure stirrup size: _____ (specify size)

Confirm spacing between stirrups: _____ (specify spacing)

Check for dowels and their placement

Verify dowel size and length: _____ (specify size)

Confirm dowel embedment depth: _____ (specify depth)

Inspect any splices in the reinforcement

Check splice length: _____ (specify length)

Ensure proper overlap and bonding of spliced bars

- Confirm the use of proper tying methods for reinforcement bars

- Inspect for corrosion or damage on steel bars

- Verify that all bars are clean and free from contaminants (e.g., oil, dirt)

- Check for compliance with the specified minimum cover requirements

- Ensure that all bars are securely tied and positioned according to the design drawings

- Confirm that all additional reinforcement (e.g., links, ties) is in place as per specifications

- Inspect the placement of any additional reinforcement for openings or penetrations

- Ensure that reinforcement is not displaced during concrete placement

- Verify that any required protective coatings on reinforcement are applied

- Document any discrepancies or issues found during the inspection for follow-up

This comprehensive checklist will help ensure that all aspects of the steel reinforcement are thoroughly inspected and documented

Formwork Inspection

Verify formwork integrity and stability before concrete placement.

Ensure formwork dimensions match design specifications.

Check for proper sealing to prevent leakage of concrete.

Concrete Quality Check

Documentation

Follow-Up Actions

Schedule any necessary repairs or re-inspections.

Discuss results with the construction team and modify plans if needed.
