PRINCIPAL EXPERIENCE

- Nondestructive Evaluation (NDE) for structural integrity of reinforced

concrete structures, condition assessment and as-built survey using a

wide variety of techniques, including Ground Penetrating Radar (GPR),

Infrared Thermography, and stress wave methods such as Impulse

Response, Impact Echo, Ultrasonic Pulse Velocity, Ultrasonic Pulse

Echo, etc

- Nondestructive Evaluation (NDE) for structural integrity of reinforced

concrete structures, condition assessment and as-built survey using a

wide variety of techniques, including Ground Penetrating Radar (GPR),

Infrared Thermography, and stress wave methods such as Impulse

- Response, Impact Echo, Ultrasonic Pulse Velocity, Ultrasonic Pulse

Echo, etc.

- Use of Video Borescope for post-tensioning bridge duct for void

Evaluation

- Conventional Nondestructive and Semi-destructive methods for in-situ

concrete Strength and durability evaluation, including Corrosion

assessment, Maturity profile

- Quality Control and inspection during construction phase of concrete

structures

- Involvement in general building structural element repair

- Knowledge of principal ASTM, ACI and ASSHTO Standards for concrete and

soil testing

- Structural evaluation and conditional survey of reinforced concrete

structures with performance issues.

- Documentation of structural distress and investigation into cause of

failure.

- Concrete Materials mix design and Strength performance related works

My experiences with civil nondestructive Evaluation (NDE) practice also

include:

- Evaluation of pile integrity

- Acoustic Emission Technique for Concrete structure Monitoring

- Evaluation of bridge structure, such as detection of void and

corrosion in grouted post tensioned tendon ducts in box girder bridges

and bridge deck delamination survey.

- Integrity evaluation of historical structure for conservation.

- Evaluation of masonry wall structure for reinforcement and grouting.

- Underground utility mapping for site clearance.

- Evaluation of large-scale foundation, dam, tunnel and Coker structure

for consolidation issue.

- Evaluation of fire damaged structures.

- Ultrasonic flaw examination for steel bridge pins.

- Involved in developing new technique. One new Technique is under

review for patent application or standardization (New Technique to

monitoring Fresh Concrete Time of Set by Pulse Velocity

- Quality Control during construction using NDT techniques
