Abstract

Two of the most commonly offered construction programs are Construction Management (CM) and Construction Engineering (ConE). While "engineering" and "management" are supposedly two distinct streams of education, the differences between ConE and CM becomes blurred in real life situations. The objectives of the research presented in this paper was to shed light on the curricular differences between CONE and CM programs and define the state-of-the-art CONE and CM curriculums. To achieve these objectives, we first created a theoretical framework of six categories of skill sets required of construction professionals in life cycle of a project. Then, we collected the curriculums of all CONE and CM programs accredited by Accrediting Board for Engineering and Technology (ABET). Finally, using a structured data-driven approach, we compared the curriculums of the programs based on the number of credit hours of coursework related to different categories of skills and developed typical CONE and CM curriculums. The results of this study will help higher education institutions to develop new or modify existing construction programs based on the required skills of their graduates and the state-of-the-art curriculums of CONE and CM programs. In particular, the results will help cross-listing common CONE and CM courses in colleges and universities that offer both programs. [ABSTRACT FROM AUTHOR]

Abstract

Civil infrastructure systems transform over the long-term due to complex interactions among socio-environmental stressors, degradation of physical networks, and decision-making processes of infrastructure agencies. To incorporate such complex transformation mechanisms into infrastructure cost management, this study integrates simulation modeling and life-cycle cost analysis (LCCA) to create a framework for dynamic network-level LCCA in infrastructure systems. The proposed framework was implemented using a multi-agent simulation model in a numerical case study related to a road network affected by sea-level rise, population growth, and uncertain maintenance funding. The results include identification of several state transition, and tipping point behaviors at which small changes in service demand, maintenance budget, and adaptation investment may result in significant improvement in network cost and performance conditions. The results show the capability of the proposed framework in modeling the long-term trajectories of life-cycle costs at the network level under different stressors and decision scenarios.

15. Exploratory Assessment of Roadway Infrastructure Adaptation to the Impacts of Sea-Level Rise

Author

Batouli, Mostafa and Batouli, Mostafa

Abstract

Transportation agencies in coastal urban areas face a significant challenge to enhance the long-term resilience of their networks to flooding and storm surge events exacerbated by sea level rise. The problem of sea-level rise adaptation is characterized by deep uncertainty that makes it complex to assess the value of adaptation investments. To enable informed adaptation decisions, the present study created a dynamic stochastic modeling framework based on the theoretical underpinnings of complex adaptive systems that integrates: (i) stochastic simulation of sea-level rise stressors based on the data obtained from downscaled climate studies pertaining to future projections of sea-level and precipitation; (ii) dynamic modeling of roadway conditions by considering regular decay of roadways, as well as structural damages caused by storm surge events; and (iii) a decision-theoretic modeling of agency infrastructure management and adaptation processes based on cognitive psychology, bounded rationality, and regret theories. In this framework, resilience is examined based on trend changes in the network performance measures (e.g., life cycle costs and performance). The created framework and model were tested in a case study related to the road network of the city of Miami-Beach, which global assessments rank first iv among the world's urban areas most exposed to sea-level rise risks. The results indicated that: (i) SLR Adaptation investment and life cycle costs of roadway infrastructure are negatively correlated. In addition, it was shown that the sensitivity of network’s life cycle cost to actual sea-level rise scenario decreases when adaptation investment increases. These finding emphasize the importance of proactive improvement of the network resilience to alleviate the long-term costs of sea-level rise. (ii) When funding is sufficient for all required adaptation actions, mid-term adaptation planning yields lower life cycle cost. When funding is insufficient, aggregated i

17. A review of the current knowledge and practice related to project progress and performance assessment

Abstract

Assessment of true project progress and performance is of critical importance in the successful delivery of construction projects. Major challenges related to measuring project progress and performance are the lack of consistent, reliable, and objective metrics and indicators and the lack of appropriate interpretation of these data for establishing suitable corrective action plans. The objective of this paper is to provide a review of existing applied knowledge and practices pertaining to methods, metrics and indicators for progress measurement, performance assessment and forecasting, as well as performance influencing factors, evaluating the shortcomings of the current approaches, and providing recommendations for improvement. The findings of this paper are primarily based on a comprehensive literature review and limited discussions with industry experts in the following areas: (1) methods and metrics used for progress measurement, (2) metrics and indicators used for performance assessment and forecasting, and (3) other metrics that can influence project progress and performance (e.g., risk, safety, and quality). Several industry and academic publications are reviewed including the reports from the Construction Industry Institute (CII), guidelines developed by professional organizations (e.g. Project Management Institute, Association for the Advancement of Cost Engineering International), and scholarly publications. Industry experts serving on the CII research team (RT-322) also provide their insights. Based on the extensive review of the relevant literature, this paper identifies limitations of various measures, metrics and indicators across different project control levels. A framework depicting the current project control process is provided along with a gap analysis related to the problems associated with this approach.

18. Assessment of network-level environmental sustainability in infrastructure systems using service and performance adjusted life cycle analysis

Author

Batouli, Mostafa and Mostafavi, Ali

Abstract

Managing environmental impacts of civil infrastructure systems is critical for fostering sustainable development. However, despite the growing body of literature, an integrated methodology that captures the specific traits of infrastructure systems for a network-level environmental impact assessment is still missing. The objective of this paper is to propose a novel methodology [called Service and Performance Adjusted Life Cycle Assessment (SPA-LCA)] for addressing the limitations of the traditional LCA in environmental assessment of infrastructure networks. The SPA-LCA methodology adopts a service-based accounting approach to enable aggregation of the impacts pertaining to assets with different functions and service life expectancies at the network level. In the proposed SPA-LCA methodology, first, through conducting traditional asset-level LCA, life cycle inventories for the assets are determined. Second, the life cycle inventories are disaggregated to performance-sensitive and none-sensitive impacts. Then, using a hybrid mathematical/agent-based simulation model, the levels of service and performance are simulated for different assets in the network across the analysis horizon. Finally, the environmental impacts are determined for each year based on the levels of service and performance. The application of the proposed SPA-LCA method is demonstrated in environmental assessment of a road network. The results highlight the capabilities of SPA-LCA in providing better insight regarding environmental performance of infrastructure networks
