    A TOOL FOR QUANTIFYING THE CARBON FOOTPRINT OF CONSTRUCTION PROJECTS IN THE TRANSPORTATION SECTOR
    (2010) Melanta, Suvish; Hooks, Elise M; Civil Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    The U.S. construction industry ranks third in the nation in its production of carbon dioxide emissions. Increasing global pressure towards developing emissions reduction strategies is bound to affect the construction industry. The objective of this thesis was to develop a tool to estimate the carbon footprint of construction projects associated with transportation infrastructure. The tool determines emissions from an inventory of equipment, construction processes, and credits efforts to reduce emissions, while incorporating recent and future greenhouse gas (GHG) policies on quantifying emissions. This tool will enable construction companies to identify sources and reduce emissions, while also allowing state agencies to monitor these companies in accordance with GHG laws. The tool was applied to data associated with the construction of the Intercounty Connector, a new roadway that will connect counties in Maryland. Application of the tool to this case study showed its utility and highlighted the need for reduction strategies.

    Construction Project Organizational Structuring
    (2005-04-20) Salgado, Carlos; Baecher, Gregory B; Civil Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    This dissertation presents an extended research study of project organizational structuring design, using Mintzberg's design parameters of organization and Lucas' IT-enabled variables on construction building project organizations. To the design parameters of unit grouping, unit size, liaison devices, planning and control systems, decision-making system and design of positions, this dissertation study simultaneously considers virtual components, technological leveling, technological matrixing, electronic linking and communications. This study used Yin's multiple case holistic design approach for this extended research study with data from major successful building construction projects to illustrate the use of this extended view and compare its findings. Based on this extended research study, this dissertation develops a practical methodology for construction project organizational structuring design. Furthermore, this dissertation applied Robbins' measures of organization structure (complexity, formalization and centralization) for corroboration.
