Investigating Students’ Perception Using Construction Management Simulations, Saeed Rokooei, James D. Goedert, Asregedew Woldesenbet

Department of Construction Engineering and Management: Faculty Publications

Today, construction programs are incorporating a wide variety of active learning methods in their curricula to improve student learning outcomes and induce a more knowledge retention rate. Simulations and educational games are one of the fast growing and effective active learning methods that have been implemented in many programs. However, there are few instances of such learning methods applied in construction programs and a limited number of research projects have been conducted to investigate short-term and long-term outcomes of these methods and applications. This paper presents construction students’ perceptions of tested simulations with regards to the features, knowledge gained, level …

A System-Of-Systems Framework For Assessment Of Resilience In Complex Construction Projects, Jin Zhu

FIU Electronic Theses and Dissertations

Uncertainty is a major reason of low efficiency in construction projects. Traditional approaches in dealing with uncertainty in projects focus on risk identification, mitigation, and transfer. These risk-based approaches may protect projects from identified risks. However, they cannot ensure the success of projects in environments with deep uncertainty. Hence, there is a need for a paradigm shift from risk-based to resilience-based approaches. A resilience-based approach focuses on enhancing project resilience as a capability to cope with known and unknown uncertainty. The objective of this research is to fill the knowledge gap and create the theory of resilience in the context …

Estimation Of Optimal Productivity In Labor-Intensive Construction Operations, Krishna Prasad Kisi

Department of Construction Engineering and Management: Dissertations, Theses, and Student Research

In an attempt to evaluate the efficiency of labor-intensive construction operations, project managers typically compare actual with historical productivity for equivalent operations. However, this approach toward examining productivity only provides a relative benchmark for efficiency and may lead to the characterization of operations as objectively efficient when in reality such operations might simply be comparably efficient.

Optimal productivity is the highest sustainable productivity achievable under good management and typical field conditions. Optimal productivity is useful in the determination of the absolute efficiency of construction operations because an accurate estimate of optimal labor productivity allows for the comparison of actual vs. …

Assessment Of Policies For Innovative Financing In Infrastructure Systems, Ali Mostafavi, Dulcy Abraham, Charlene Sullivan

Infrastructure System-of-Systems (I-SoS ) Research Group

Infrastructure systems are drivers of the economy in the nation. A dollar spent on infrastructure development yields roughly double the initial spending in ultimate economic output in the short term; and over a twenty-year period, and generalized ‘public investment’ produces an aggregated $3.21 of economic activity per $1.00 spent [1]. Thus, formulation of policies pertaining to infrastructure investment and development is of significance affecting the social and economic wellbeing of the nation. The aim of this policy brief is to evaluate innovative financing in infrastructure systems from two different perspectives: (1) through consideration of the current condition of infrastructure in …

The Impact Of Various Steel Stud Wall Frame Components On Energy Efficiency Analysis – Case Study, Aiyin Jiang

Construction Management Faculty Research and Scholarship

Steel stud framing is an excellent alternative to wood stud framing in residential construction. Steel framing is structurally sound, sustainable, and resistant to mold and insect infestation. However, the use of steel framing in the residential market remains low, due in large part to concerns on the thermal performance of steel. Over the past several years, engineers and constructors have increased the thermal resistance of steel stud walls through various wall assembly improvements, the impact of these components on energy efficiency is unclear. This study applies computer software to simulate the performance of various steel stud wall system assemblies. This …

ECT Fact Sheets

The Dynamic Construction Visualizer (DCV) is general-purpose 3D visualization system that allows simulation model developers to animate modeled operations with chronological and spatial accuracy in 3D virtual space. The system is independent of any particular simulation-modeling program or CAD modeling software.

Stroboscope, Purdue Ect Team

ECT Fact Sheets

STROBOSCOPE is an acronym for STate and Resource Based Simulation of COnstructionProcEsses. It is a general-purpose simulation programming language that has been designed for the simulation of very complex construction processes that involve many different types of resources. STROBOSCOPE models are based on a network of interconnected modeling elements and on a series of programming statements that give the elements unique behavior and control the simulation.

Prosidyc: Simulation Program For Construction Operations, Purdue Ect Team

ECT Fact Sheets

PROSIDYC is a system for simulating construction operations jointly developed by the Planning and Methods Unit of Dragados y Construcciones, Madrid, Spain and the Division of Construction Engineering & Management at Purdue University. PROject SImulation Dragados Y Construcciones (PROSIDYC) is a computer based system for analyzing construction job site production processes. It is used to improve productivity in the field by studying resource utilization and cycle times and identifying opportunities for production improvement. PROSIDYC uses the CYCLic Operations NEtwork (CYCLONE) modeling format originally developed by Daniel W. Halpin

Virtualstep: 4d Simulation, Purdue Ect Team

ECT Fact Sheets

The main value from 4D is derived from using it proactively to visualize the construction sequence. Another benefit is the ability to run what-if scenarios to determine optimum scheduling and resource management. Also, by linking 3D drawings to a project schedule, all project stakeholders, from the owner to the tiling subcontractor, can see how the project is supposed to progress. VirtualSTEP Products include 4D Project Navigator, Conflict Coordinator, Project Reporter, and Project Analyzer. All these products are web-based.
