    Leed Certification: a Comparison of Contractors' Perspectives
    (Research Publishing Services, 2013) Doğan, Sevgi Zeynep; Günhan, Suat; Gerçek, Bilge; Arditi, David
    The Leadership in Energy and Environmental Design (LEED) certification system for green buildings has been used extensively in the US and has gained increased attention in developing countries as well. The related literature focuses extensively on the perspectives of owners and designers, whereas constructors' role receives less attention. One significant research is based on a survey administered to 22 contractors, who built LEED certified green building projects in the US. The survey inquired about earned LEED credits and best practices in LEED certification process regarding past experiences. The same survey was administered to seven Turkish contractors, who also built LEED certified green buildings in Turkey. The similarities and differences between US and Turkish constructors' perspectives were studied. Both groups stated that the LEED process was slightly difficult or was just straightforward. US contractors needed a lot of additional time for the LEED documentation; Turkish contractors required no extra time. LEED certification system incurred a little additional cost for US contractors; however Turkish contractors mentioned about up to 10% additional project costs. The achieved LEED credits from materials and resources, and indoor environmental quality by the two groups of contractors were highly correlated. Both groups emphasized the inclusion of LEED documentation and specifications in coordination meetings and in subcontracts to streamline the process; and emphasized the early collaboration of the entire project team for earning LEED credits.

    Evaluating the Project Coordination Performance Using Information Centrality
    (American Society of Civil Engineers, 2014) Timurcan, Pelin İpek; Doğan, Sevgi Zeynep
    Evaluation of coordination performance in a project network requires reliable measures and monitoring methods for effective management. Recent literature includes studies addressing the relationship between coordinative activity and the configuration of communication networks. In these works, the role of network centrality is investigated through the basic standard centrality measures of degree, betweenness, and closeness. Current social network analysis research emphasizes new formulations of centrality measures for robust structural analysis of project networks. This paper presents a novel approach for measuring network centrality using the concept of information centrality. It is based on the idea that all paths carry information. The significance of information centrality values for the actors in a directional signage project at Istanbul Sabiha Gokcen International Airport is investigated. A centrality index is defined for each firm based on the average of the four measures of centrality. Findings suggest the existence of a high correlation between coordination scores and the centrality indexes. A centrality index augmented by an information centrality measure has potential for assessing the coordination performance in construction management research, and it is promising for the structural analysis of project communication networks. © 2014 American Society of Civil Engineers.

    Coordination Process and Network Centrality in Isgi Airport's Wayfinding Project
    (American Society of Civil Engineers, 2012) Doğan, Sevgi Zeynep; Günhan, Suat; Erbasaranoglu, Bengi
    Coordination is integral to operational efficiency of construction projects. Coordination process relies on managing dependent activities and the structural centrality in social networks is strategic to project actor's management activity. This study aims to explore the effects of network centrality on coordination performance. Network centrality concepts and coordination theory are examined via Email communication data of Istanbul Sabiha Gökçen International Airport's (ISGIA) New Terminal Building Wayfinding and Signage Design Project (WSDP) actors. E-mail data mining for identifying different coordination dependencies is derived from the constructs of Malone's (1988) coordination theory and used to measure the actors' coordination scores. Social network matrix of information exchange network is constructed to calculate degree, betweenness and closeness centrality measures. ISGIA data analysis suggests a significant relationship between out-degree, outcloseness centrality and coordination. Findings highlight that out- network centralities support the ability of an actor to coordinate the dependent actions of other project actors; and the design and construction practices rely on the central position in a network in mapping effective coordination processes. © 2012 ASCE.

    Non-Verbal Cues: Improving Communication in Construction Projects
    (American Society for Engineering Education, 2012) Günhan, Suat; Şenol, Gülşen; Doğan, Sevgi Zeynep
    Construction industry is a dynamic, project based industry in where many problems occur due to communication issues. As it is proven that effective communication and conflict resolution abilities have a strong correlation between them, communication in the construction industry should constantly be improved. Unfortunately, the existing construction curricula do not offer enough courses which would help students to communicate effectively. Embedding technical communication into curricula and introducing courses such as Construction Communication aiming on producing construction management (CM) graduates with good writing and speaking skills are necessary. However, written and verbal languages are not the sole means by which individuals exchange information. Non-verbal cues play a significant role in communication. Therefore it is necessary for CM graduates to master the skills of using and reading body language. The literature study for the subject of communication in the education shows that body language and non-verbal communication were not taken into consideration yet. They are primarily the subject areas of anthropologists, linguists, and social psychologists. This paper aims reviewing the role of non-verbal communication skills in construction business and highlights the importance of bringing the topic into classroom. © 2012 American Society for Engineering Education.
