Research Ambitions

Digital models are becoming the basis for design, analysis, simulation, construction planning, construction execution, operation and maintenance. As various tools and technology for virtual design and construction mature, it is important to integrate them with existing processes and work flows in the industry. There is a need for addressing seamless data exchange between users and systems, in what is called interoperability. With the goal of an open-BIM framework catering to the entire lifecycle of building and infrastructure projects in mind, I envision a three-tiered approach, namely fundamental, applied and socio-economic, towards conducting my research.

At one end of the spectrum, I plan to direct future research in resolving this interoperability problem in design, engineering and construction at a fundamental level by specifying new methods and standards. An example for such fundamental research is an automated information exchange protocol using Industry Foundation Classes (IFC). In terms of applied research, I plan to focus on developing and integrating new technologies and solutions for virtual design and construction. Automated rapid prototyping of a rich and detailed information model from spatial data, for as-built control and facility management are examples of applied research I intend to pursue in the future. Improvements in interoperability research and better work flows in industry will lead to savings in the form of reduced wastage of resources and rework.

I envision an overall improvement in the quality of products for construction community with the help of new computer aided design tools, new special purpose applications, and innovative processes, which will transfer to new lines of education. The open-BIM framework, which is my long term interest, will lead to disseminating the benefits of research to the entire industry, for example, developing an integrated dashboard for building performance monitoring to achieve a better LEED rating, thereby, improving the socio-economic fabric of society leading to sustainable development.

Research Ambitions

The mission of the Economics of the Sustainable Built Environment (ESBE) Lab, which I funded at Georgia Tech in fall 2009, is to develop the state-of-the-art financial models for enhancing efficient and effective investments in built environment assets. Avoiding under- or over-investment contributes directly to the objective of sustainable development, which aims to maximize future benefits considering the resources used. Examples of Research Initiatives are:

• Energy-efficient green buildings: Flexible Technologies and Systems for Green-Convertible Buildings. This project is a timely effort to extensively identify, model, and analyze flexibility in sustainable building design. Development of a flexibility identification framework will provide a novel approach for building designers and retrofitters to enhance the future utilization of renewable energy technologies, such as PV Systems, and facilitate the conversion of existing buildings to energy-efficient buildings.
• Transportation systems: Economic Analysis of Public-Private Partnership (PPP) Highway Projects under Traffic Uncertainty. Public-Private Partnerships (PPPs) have often failed primary due to the lack of proper financial analysis and inappropriate risk sharing mechanisms between public and private sectors. In this research program, we use the real option theory to evaluate the financial performance of PPPs under evolving tolled-road revenue uncertainty.
• Healthcare planning and design: Enhancing the Value of Healthcare Facilities by Flexible Design and Planning. Uncertainty about healthcare environment is considerably important for healthcare infrastructure planners and hospital designers. Incorporating appropriate flexible features in planning and design of healthcare facilities is an effective strategy to manage uncertainty about the healthcare environment.

Daniel Baerlecken is Visiting Assistant Professor at Georgia Institute of Technology. He teaches digital design and fabrication. His research focuses on the exploration of the algorithmic potential of computing and of the resulting innovative architectural forms.

Kevin Shankwiler is an Assistant Professor in the School of Industrial Design. His research focuses on the use of parametric modeling and design with a particular interest in product customization. He holds a Bachelor of Science and Master of Industrial Design from Georgia Tech.

Professor Brian Bowen was appointed the College of Architecture’s first Professor of Practice in 2007. Prior to this since 2000, he supported the College’s Continuing Education Program with specific focus on courses in Managing A & E Practices and Contracting Companies. He retired in 2000 as President of Hanscomb Inc., an international construction consulting company active worldwide in managing construction projects and programs. He was trained in England as a Quantity Surveyor joining Hanscomb in 1960 in London, moving to Montreal in 1961 and then Atlanta in 1982.

Current research is directed in three main quarters:
1.    Knowing how the American construction industry evolved from colonial times for the purpose of understanding its current structures, organization, processes and methods used to deliver its projects.
2.    Studying the current industry in order to devise improvements in productivity and in value delivered to its clients.
3.    Examining methods used in other countries construction practices and processes as a potential source of ideas for improvements in the US.
