Teaching construction project management with BIM support: Experience and lessons learned

This paper presents experiences and lessons learned during the introduction of Building Information Models (BIM) in construction engineering project management courses. We illustratively show that the introduction of BIM-based project management tools helped the teachers of two courses to develop more realistic project-based class assignments that supported students with learning how to apply different formal project management methods to real-world project management problems. In particular, we show that the introduction of BIM allows educators to design a class project that allowed the use of more realistic cases that better simulate real-world project conditions, helped students to learn how different project management methods integrate with each other, integrate change management tasks in a class assignment, and learn how to optimize project plans.

Power plants as megaprojects: Using empirics to shape policy,planning, and construction management

Megaprojects are historically associated with poor delivery, both in terms of schedule and cost performance. Empirical research is required to determine which characteristics of megaprojects affect schedule and cost performance. Capital-intensive power plants can be understood as megaprojects and time delays and cost escalation during the construction phase can undermine their overall economic viability. This paper presents a systematic, empirically based methodology that employs the Fisher Exact test to identify the characteristics of power plant megaprojects (PPMs) that correlate with schedule and cost performance. We present the results of applying this methodology to a dataset of 12 PPMs using nuclear, coal, and renewable resources as case studies. The results highlight the importance of modular technologies, project governance, and external stakeholder involvement. Key findings both support and contradict the literature. The paper provides two major original contributions. First, we present and apply a systematic, empirical and statistical approach to understanding PPMs planning and construction. Second, we show how this approach can be used to inform public policy and project management with regard to PPMs.

Why and how do project management offices change? A structural analysis approach

The growing popularity of Project Management Offices (PMOs) as organizational structures is grounded in the assumption they support more efficient and effective project management for better strategy implementation. However, research emphasizes they fail to deliver expected value: their unstable nature precludes the delivery of long-term benefits. This is compounded by the absence of a theory of PMO change and adaptation. Recent research, taking a co-evolution lens rooted in evolutionary theory, suggests that PMOs should be studied in relation to the broader organizational context, in order to better capture the dynamic interplay and fit between them. In this study, taking a routine perspective as micro-foundation and unit of analysis, we focus on the co-evolution between PMO and Project Portfolio Management (PfM) as organizational capability for six case studies. A structural analysis of the relational routines' system between PMO, PfM and the Organizational context allow us to unveil dynamics at stake, i.e. why and how changes occur, as well as eigen behaviors and the changing states of various routines elements (influential, mediating, dependent or not-influential). This study makes five contributions. We show that: 1) PMO and PfM can be conceptualized as collections of routines, 2) PMO and PfM co-evolve over time to adapt to organizational context influence, 3) the co-evolution of a routines' system, abstracted as a non-trivial machine, exhibits an eigen behavior, 4) applying a structural analysis approach allows to simulate the dynamics of a routines' system and to unveil the role of key routine elements and 5) eigen values of routines' systems allow to characterize their eigen behavior.     

下荆江熊家洲至城陵矶弯曲型河段河床调整规律

三峡水库运用后, 坝下游水沙过程发生了较大调整, 对下荆江熊家洲至城陵矶弯曲型河段河床冲淤演变造成较大影响, 从而对本河段河势稳定、防洪、航运等可能造成不利的影响, 基于此, 根据最新实测资料分析水沙条件变 化及其对本河段河床调整规律的影响。研究成果显示: 三峡水库运用后, 水流含沙量大幅减小, 且水库调蓄导致熊 家洲至城陵矶河段在枯水期径流量明显增加, 使弯道主流长期偏向于凸岸, 引起凸岸边滩大幅冲刷, 这是近期该河段发生“撇弯切滩”的主要原因之一; 随着三峡上游干支流水库群陆续建成运用, 坝下游河道将会长期遭受清水冲 刷, 河床仍将呈单向冲刷下切的趋势, 弯顶段主流平面摆动仍将较大, 弯道顶冲点也将相应下移, 导致主流贴岸距离 进一步下延, 引起河道岸线的崩退, 未来一段时期内典型弯曲型河道的局部河势变化仍将明显。     

Team formation instruments to enhance learner interactions in open learning environments

Open learning environments, such as Massive Open Online Courses (MOOCs), often lack adequate learner collaboration opportunities; they are also plagued by high levels of drop-out. Introducing project-based learning (PBL) can enhance learner collaboration and motivation, but PBL does not easily scale up into MOOCS. To support definition and staffing of projects, team formation principles and algorithms are introduced to form productive, creative, or learning teams. These use data on the project and on learner knowledge, personality and preferences. A study was carried out to validate the principles and the algorithms. Students (n = 168) and educational practitioners (n = 56) provided the data. The principles for learning teams and productive teams were accepted, while the principle for creative teams could not. The algorithms were validated using team classifying tasks and team ranking tasks. The practitioners classify and rank small productive, creative and learning teams in accordance with the algorithms, thereby validating the algorithms outcomes. When team size grows, for practitioners, forming teams quickly becomes complex, as demonstrated by the increased divergence in ranking and classifying accuracy. Discussion of the results, conclusions, and directions for future research are provided.
