  • Funding Agency: Ministry of Land, Infrastructure, and Transport
  • Amount: about $2,200,000 (for 4 years) 
  • The purpose of this study is to develop human resource for overseas construction and engineering. The curriculum for the department of construction has been developed. Students in the department get financial support from this project (tuition and internship opportunity).

08/2014 - 08/2015

  • Role: PI
  • Funding Agency: Ministry of Land, Infrastructure, and Transport
  • Amount: about $164,000 
  • The purpose of this study is to develop a training program for construction management (CM). The program, customized for Cambodia, was applied by educating  20 people working in the Cambodian construction industry for two weeks in Seoul, Korea.

01/2013 - 12/2013

  • Role: PI
  • Funding Agency: Construction Industry Institute
  • Amount: $16,000/year
  • The purpose of this study is to reinvigorate the benchmarking efforts for Construction Industry Institute (CII). This will form the point of departure for the next phase benchmarking research in the CII Performance Assessment.

  • Role: PI (Subcontract through Chung-Ang University)
  • Funding Agency: Korea Institute of Construction and Transportation Technology Evaluation and Planning
  • Amount: \6,000,000 (about $55,500)
  • The purpose of this study is to compare CO2 emission for various construction processes in the airport pavement construction.

01/2012 - 08/2013 

  • Role: Co-PI (PI: Dr. Emre Bayraktar)
  • Funding Agency: Florida Department of Transportation
  • Amount: $149,959
  • The purpose of this study is to determine vibration limits for structures and buried utilities, determine anticipated vibration levels generated by foundation and pavement construction equipment and prediction methodologies, and evaluate mitigation techniques.

04/2008 - 07/2011

  • Role: Graduate Research Assistant (Supervisor: Dr. William O’Brien)
  • Funding Agency: Construction Industry Institute (CII)
  • This study provides a systematic assessment of integration-technology adoption. Two tools developed by the research help organizations assess their processes and evaluate integration opportunities in consideration of market/legal, organizational and process, and people-related issues. By applying the tools to practical cases, the study identifies major benefits and hindrances of information integration implementation in the construction industry. As a graduate research assistant, I developed one tool in Microsoft Excel, and collected and validated cases through interviews. I was also involved in publishing CII reports.
