Akinci TITLE: The Need For Prompt Schedule Update By Utilizing Reality Capture Technologies: A Case Study ABSTRACT: Updating of construction schedules involves prompt and accurate capture of facts from a construction site for progress assessment and for learning from the assessment of site related facts to improve scheduling of upcoming activities. This paper discusses a case study being conducted on a highway construction project to understand the need for and the current practice of capturing, transferring and storing site related factual data for assessing the status of a project and of how this information is used in scheduling of upcoming activities. It highlights the challenges and opportunities for improvements observed in data collection and situation assessment processes. The case study findings are used as a basis for a discussion on possible ways of improving the current process by utilizing automated data capture technologies. 2004 NSF Design, Service and Manufacturing Grantees and Research Conference Dallas-Texas, January 5-8 2004 AUTHORS: M.K. Pekericli, B. Akinci, I. Karaesmen TITLE: Engineering the Incorporation of Information Technologies into Construction Service Networks ABSTRACT: In project network organizations, information is critical for streamlining operations. Collection, analysis and communication of project information and coordination of information exchanges between different project participants are essential for a project's success. Information technology (IT) systems can greatly influence the effectiveness of management of information not only within a project team, but also between the project team and other project-related organizations. IT systems have been rapidly growing over the last decade providing a diverse suite of systems to be utilized within project organizations. A better understanding of IT choices and a formalized decision making about selection of a set of them for a given project are of utmost importance. Currently, the decisions on selecting a set of systems to incorporate on a given project are done in an ad-hoc and trial-and-error basis. In this paper, we provide a review of the research on use of IT in construction management. We present a case study in construction to show how IT (or lack of IT) enables (or hampers) effective operations, and discuss the need for a framework for selecting IT in construction projects.

Karaesmen TITLE: A Look at Overlooking Problems for Networks ABSTRACT: Building on our earlier work on overbooking with substitutable resources, we show how centralized and de-centralized planning affect the system performance. Structural results and numerical examples are presented. 4th Joint Symposium on IT in Civil Engineering, Nashville-Tennessee, November 12-15, 2003 AUTHORS: M.K. Pekericli, B. Akinci, I. Karaesmen TITLE: Modeling Information Dependencies in Construction Project Network Organizations ABSTRACT: This ongoing study intends to explore and formalize the information dependency patterns in network forms of organizations in construction project management. In construction projects, information is critical for seamless and cost-effective operations. Communication of project information and coordination of information exchanges between different project participants are essential for a project's success. On the other hand, a better understanding of information dependencies between participants is of utmost importance for strategic choices on information technology (IT) applications since decisions on IT investments greatly influence the effectiveness of not only internal communications within a project team, but also the interactions of the project team with other project-related organizations. In this paper, we provide a case study to highlight the characteristics of information exchanges and dependencies in construction project organizations. We introduce approaches that are well-accepted by organization theorists in analyzing network organizations and assess their strengths and limitations in modeling information dependencies in construction projects. We focus specifically on dependency structure matrix, social network analysis and computational organization theory since these methodologies have been applied to construction project organizations. These methods, alone, have limitations in supporting decisions on investments regarding IT applications. We conclude with a research roadmap that highlights the research needs for modeling information dependencies within construction project organizations to enable effective IT investments.
