Abstract
Slipform construction technique offers unrivalled performance in terms of speed and accuracy of construction and the safe construction of high rise reinforced concrete structures, Nevertheless, effective management of Slipforming operations is critical due to operation’s linearity that is considered a major source of planning and proper project management complications. Accordingly, this thesis aims to develop a comprehensive decision making tool for feasibility studies of Slipform projects concerning four major project management domains, namely, Time, Cost, Quality and safety domains by utilizing Building Information Modeling as the most emerging technology in the Architectural, Engineering and Construction industry for design and facility management of construction projects, and reinforced by Discrete Event Simulation as scenario analysis method for achieving the thesis aim and goals. Consequently, this thesis proposes an integrated framework and software using a C sharp language and a graphical user interface, named Schedule Cost Quality and Safety module (SCQS) to assess and compute the aforementioned project management domains of Slipforming projects by a two stage methodology; First: Develop an integrated Building Information Modeling and Discrete Event Simulation framework for the purpose of automating the generation of time schedules (4D), cost estimates (5D), this software is reinforced by both Building Information Modeling and Discrete Event Simulation capabilities. Enhanced by Building Information Modeling’s extracted information, the quantities are used to generate Discrete Event Simulation input data in order to calculate the execution times for construction processes and exchange data between various software platforms; and Second: Linking the aforementioned 4D model with quality specifications and safety procedures to assess quality of project defined elements in study by developing a Product Organization Process model that integrates the specifications, procedures, quality inspection plan process and checklists with the 4D model to present a decision whether to accept and proceed or to reject and issue a nonconformance report (6D), in addition to safety visualization of slip-forming construction site for assessing in visualizing safety procedures conducted through Slipform projects for the following aspects; Site layout plans and crane reach visualization related to a crane collapse, Modelling of safety railings for falling protection and Site safety communication (7D). Findings of research development is expected to transform the operation of traditionally managing and coordinating Slipform projects manually from design till project closing, moreover increase the dependence on Discrete Event Simulation after overcoming Data Input Management source, and in addition to increase the awareness of utilizing new technologies as Building Information Modeling in the Egyptian construction market. Moreover, The software was tested using various case studies to assess validation and verification of the software, validation is assessed qualitatively and verification is assessed quantitatively, showing valid software actions transaction and verified results robust of (98±4%) for the overall accuracy of the software. Eventually, while it is clear that the findings will serve practitioners and researchers involved in Slipforming operations as a practical decision tool for selection and adoption of Slipform system in construction industry, this thesis recommends increasing the capability of the proposed software by further integration with multiple domains and construction types, in addition to establishing governmental rules to help spreading new technologies through Egyptian construction industry.
