He has received PhD in risk management in International Construction Projects as an external part-time researcher with Vels University Chennai, India, on March-2017 and received civil engineering degree from Kamraj University Madurai-India on April 2000. He has received MBA in Project Management from Sikkim Manipal University-India in 2012. His professional interests focus on Construction/Project Management, Structural Management and Risk Management in the construction projects and his current projects include Kuwait International Airport Project, College of Engineering and Petroleum, College of Science and College of Business for women in the Sabah Al Salim Al Sabah University City, Shadadiya–Kuwait and he has published 50 papers in International and National Journals and Given many keynote speeches about Skyscrapers, Risk management and constructability’s considerations in the international conferences
The most popular system for supporting long-span roofs is steel truss in commercial buildings, such as warehouses and aircraft hangars. There are numerous advantages of steel trusses, such as lightweight, ease of handling and erection, and geometric flexibility. However, there are some drawbacks, in terms of the material selection during the design time and material availability during the construction phase, maintenance cost, and low fire resistance. Hence In this presentation, Precast Prestress and Post-Tensioning Concrete and steel built-up box girders would be presented as an alternative to steel trusses for spans up to 40 to 50 m without intermediate supports. The design behavior and constructability perspective by illustrating by the help of CONCISE V 4.47h model. This proposed design is easy to produce, fabricate and erect and has lower construction and maintenance costs than steel trusses. the proposed design. A finite element analysis of the specimen is conducted to investigate stresses at long span precast prestress and post-tensioning and steel built-up girders. Further, the complicated transportation and erection sequence would be illustrated with practical examples to erect the heavy, long span beams.

My presentation/ lecture is also perfect platform for opining up some questions on a major problem surrounding innovation in steel structures; construction, design and performance that has arouse the interest of contactors, designers, architectural engineers and researchers for some time. The questions confront us because, i) no obviously satisfactory answer is readily apparent, ii) the problem itself is not yet apparent to many people and after completing my lecture/presentation the audience will be brought to the questions at least and thus If we can get that far, our time will be very well spent. The questions we should address are; Why Innovation, How Innovation is different from science, engineering and inventions, what are the factors/characteristics for nurturing innovation culture in steel industries. I will cast a concise lights on the above and prove that by adapting; One-Strong leadership committed to innovation, Two- Minimal hierarchy in decision making, Three- Commitment to deliverables and implementation, Four-Values disparate talents & entrepreneurship, Five- Value the creative and unconventional ideas, Six- Moves quickly and adapts readily and Seven- willingness to accept failures, the culture of innovation in steel construction industry can be nurtured. The presentation will be concluded by showing a video displaying the results of a full-scale research case study on lateral impact response of steel end plate beam to column connections and compared with finite elements modling. Coloured photos showing the behaviour of the tested elements will be displayed too

Dr. Saeed Karshenas is a professor of civil engineering at Marquette University in Milwaukee, Wisconsin, USA. He has published over 60 papers in refereed journals and conferences. His current research is focused on building information modeling and semantic representation of building data.
Building projects use a variety of software tools and information sources to support design, construction, maintenance, and operation activities. Each specialty area in the building industry uses software tools specifically designed for its functions and store data in proprietary formats that cannot be easily integrated with data generated in other areas. However, there are natural connections among various building processes that require data integration across various specialty areas and software applications. Efficient execution of various building processes requires seamless and fluid communication of data among applications used in the project lifecycle.
In recent years, the Semantic Web technology has emerged as a viable approach for structuring, interrelating, and publishing information. In the Semantic Web approach, a common vocabulary is defined for the information in a domain. The common vocabulary includes machine-interpretable definitions of various concepts in the domain and the relations among them. Creating an explicit common vocabulary for a domain provides a common understanding of the structure of the domain information for users of the information.
The paper discusses a modular approach for developing vocabularies for various building domain data and discusses custom vocabularies developed for design, cost, and schedule domains in building construction. The paper presents a case study that demonstrates the application of the Semantic Web technology for aggregating design, cost, and schedule information to answer queries or as input data to other applications.
