    extensive research studies conducted to examine the seismic response of and develop design requirements for multi-tiered concentrically braced frames, there is limited research on the seismic performance of steel MT-EBFs. Furthermore, there exist no special design requirements for MT-EBFs given that there

    are several concerns associated with the stability response of their unbraced intermediate links and columns. Due to the lack of background research, the current edition of the Canadian steel design standard, CSA S16-19, does not recognize MT-EBFs as ductile EBF. This Ph.D. research project aims to

    design standard, CSA S16-19. Special design requirements were introduced for MT-BRBFs in the 2016 edition of AISC Seismic Provisions in the U.S. to improve column stability response and control tier drift demands. However, very limited supporting research data is available to verify these requirements

    potential improvements, and develop an enhanced design method in the framework of CSA S16. This M.Sc. research project aims to evaluate the seismic response of steel MT-BRBFs designed to the Canadian and U.S. provisions and propose enhanced analysis and design methods to better represent MT-BRBF seismic

    Fabrication operations produce made-to-order structural components (such steel elements or precast concrete) for multiple construction projects, which require crews to repeat their work at a number of workstations or locations in a special manufacturing facility. Scheduling these interdependent

    techniques have been developed to facilitate modelling and analysis. However, these existing scheduling approaches fail to address the extensive resource links among projects, thereby negatively impacting the stability and feasibility of resultant project schedules and increasing management difficulties in

    different stages of the project. Hence, the workface operation realities often deviate away from the actual planning bringing down the overall productivity. Unless the changes and variations (e.g., material logistics) during operations can be sufficiently and cost-effectively reflected in the planning, the

    -term prediction serves for the design stage of a project, such as the pre-excavation of a tunnel or the pre-mining of a workface, which can be regarded as an integral assessment for the rock burst potential for the engineering field. By contrast, rock burst pre-warning serves the project construction

    and the discriminative model, and we draw a conclusion that the discriminative model is more suitable for rock burst prediction task. The fifth chapter presents a special situation when we can not trust the training labels because of various reasons. In the chapter six we talk about the essential role

    The fast-paced progress associated with offsite construction projects necessitates special attention toward project design, estimation, and planning. Traditionally, the relationship between project design and cost lacks clarity during the early design stages of a project. While design efforts aim

    to improve the project performance, compromises are made in order to meet a desired targeted cost. Target cost modelling (TCMd) provides an ideal environment to explore the available alternatives and reveal the associated financial and environmental impact on the project. Structural design, building

    envelope, heating and cooling systems, delivery of modular units, and onsite assembly are analyzed and standardized through a set of construction, costing, and energy factors in order to illustrate their indirect/direct effect on the project design, cost, and energy efficiency. This research presents a

This dissertation aims to identify and address the shortcomings that exist in current pullback determination methods during pipe installation by HDD. Throughout the study, special attention is

    Technologies (CETT) at the University of Alberta, and collected on different project sites for crossings executed in Alberta, Canada. The new proposed models have been able to simulate the recorded pullback forces, while the PRCI method failed to do so. It has been observed that the fluidic drag changes

Previous research efforts either focused on the material delivery process or the module assembly process alone, while the

    integration of both for evaluating the impact of logistics performances upon modular construction planning has yet to be addressed. Thus, a special logistics simulation template is developed based on the Simphony platform to facilitate the simulation modeling of module fabrication, transportation, assembly

    ) promote application of simulation in site layout planning of tunnelling projects by developing a special-purpose simulation tool, (4) simultaneously optimize site layout variables and construction planning variables by developing an integrated GA-simulation framework, and (5) optimize site layout planning

    Site layout planning, which involves identifying sizes and locations of temporary facilities, can have significant impacts on the safety, cost, time, and productivity of projects. Despite considerable research undertaken to improve efficiency of planning construction site layouts, most models

    developed for this purpose have overlooked the impact of facility size on project cost and cannot thoroughly model the dual impact of site layout variables (i.e., facility size and location) and construction plan variables (e.g., production rate, resources, and material delivery). In this research, given

    The Construction Industry Institute (CII) has a best practice under the heading “Front End Planning” (1995) that is meant to ensure that projects are as complete, as optimized, and as certain as possible throughout the project life cycle. In order to demonstrate this, the Project Definition Rating

    Index (PDRI) was optimized to suit underground drainage tunnel construction. The rating index has been successfully used for 2 of 3 key area workshops to demonstrate the usefulness of this tool to both the case study and the construction industry. A special purpose simulation template was created for

    use in the simulation environment Simphony, specifically for underground drainage tunnel construction. This proved to be extremely helpful in the front end planning of the case construction project to confirm alternate construction alignments, construction methods, and what type of shifts and crews

    In the current construction industry, simulation is an effective technology that can assist engineers’ decision making on project planning and estimation. The key contribution of simulation is to model uncertainty and risk occurrence during the construction process; however, this method still lacks

    a quantitative method to determine how much risk the decision maker is willing to accept. This thesis aims to develop an approach that can assist decision making on what percentile from a cumulative distribution function (CDF) of project cost reflects the organization’s risk appetite and overall

    acceptance of risk. In order to enhance this quantitative risk analysis, a special purpose template was re-developed in Simphony.Net, based on program evaluation and review technique (PERT). This template provides an integrated cost/schedule model, and transforms the model to simulation-based planning, in
