“…For infrastructure projects, the bigger the amplitude and intensity on performance evaluation, the greater the chances of success (Flyvbjerg, 2007). However, one should consider that these ventures are also sources of risks, because they involve many stakeholders (Antoniou et al, 2013), contracts and contractors (Ghosh & Jintanapakanont, 2004). The goal of identify risks and categorize them into risk factors, is to prevent negative events with large impacts on the results of the projects (Redmill, 2002;Jordão et al, 2015).…”

“…Discover the degree of complexity of the projects is part of a management model, whose purpose is to obtain the best results (Pich et al, 2002;Cooke-Davies et al, 2008;Giezen, 2012;Ahern et al, 2013;Antoniou et al, 2013).…”

“…PRO-3 states that depending of the complexity, greater effort is involved to the identification of risks (Kwak & Stoddard, 2004) and that this complexity is translated in a series of negative reflexes in the achievement of the objectives of the projects (Antoniou et al, 2013). It is also state that risk management is more intense in projects with higher levels of complexity (Barki et al, 2001;Shenhar & Dvir, 2007), the presence of risk factors grows with increasing complexity (Shenhar et al, 2005;Giezen, 2012;) and that performance tends to be better in projects with less complexity (Pich et al, 2002;Cooke-Davies et al, 2008;Antoniou et al, 2013).…”

ISSN 0104-530X (Print) ISSN 1806-9649 (Online) Resumo: Este estudo tem por objetivo compreender como se caracteriza a gestão dos fatores de risco no desempenho de projetos de infraestrutura. Para tal, utilizou-se o referencial teórico associado tanto à literatura voltada para o gerenciamento de riscos quanto sobre complexidade e desempenho de projetos. A estratégia de pesquisa utilizada baseou-se no método de estudo de casos múltiplos, compreendendo a análise de cinco empreendimentos em dois segmentos econômicos distintos. As evidências empíricas sugerem que o impacto dos fatores de risco no desempenho dos projetos depende da intensidade da gestão dos riscos e das habilidades dos gerentes de risco, mas não varia com a complexidade dos projetos. O estudo também indica que a intensidade do desempenho nas dimensões analisadas varia de acordo com a influência dos fatores considerados. Palavras-chave: Projeto de infraestrutura; Desempenho; Gerenciamento de risco; Fator de risco; Complexidade.Abstract: This study aims to understand how risk factor management is characterized in the performance of infrastructure projects. The multiple-case study methodology was used, including the analysis of five projects in two different economic sectors. Empirical evidence suggests that the impact of risk factors in the performance of projects depends on risk management intensity and on the skills of risk managers, but it does not vary with project complexity. Furthermore, the intensity of the analyzed performance dimensions may vary according to the influence of the factors considered.

“…2012); moreover, Michigan Department of Transportation (MDOT) did not witness a significant duration reduction in some of its I/D projects; albeit with an increase in cost (El-Gafy 2014). These mixed results further complicate the SHAs' already complex and essential task of selecting the appropriate type of ACM for their pavement rehabilitation projects and ensure the success of their implementation (Antoniou et al 2012); hence, the need for models to help in this task.…”

Analyzing Decision Making in Alternative Contracting for Highway Pavement Rehabilitation Projects

The negative impacts associated with highway pavement rehabilitation projects drove state highway agencies (SHAs) towards increased adoption of alternative contracting methods (ACMs) to accelerate the construction of such projects; hence, reducing these impacts on the travelling public. However, the application of such methods showed mixed results due to the lack of specific guidelines addressing the adoption of such methods and the selection of the best ACM for each project. This lack of guidelines stems from the lack of research studies examining the impact of each of these methods on the time/cost trade-off relationship in highway rehabilitation projects. Existing literature includes several studies aimed at developing generic and subjective guidelines based on past experiences that do not take into consideration the unique nature of each of these methods.Hence, this research study aimed at analyzing the SHAs' decision making process regarding two of the most-widely used ACMs: Incentive/Disincentive (I/D) and Cost + Time (A+B) contracting methods, in order to support decision makers in choosing the vi most-suitable method for their projects. To this end, two models were developed in this dissertation to examine the time/cost trade-off for each method using simulation and regression analysis. Each model was validated against real-life projects and used to assign appropriate ID and "B" values based on the SHA's desired duration reduction and available budget. Furthermore, a risk analysis module was developed to determine the most-likely duration reduction that the contractor can achieve for each project under each method.The developed models should help improve the decision making process regarding the selection and implementation of these methods in highway rehabilitation projects. For example, the models can help SHAs identify the minimum ID level that can be offered for each project and the expected duration that the contractors can bid on under the A+B contracting method. Finally, the models were contrasted and applied to real-life projects with different characteristics to verify existing guidelines and establish the candidate ACM for each project category. The findings of this study will benefit the society, SHAs, and the economy in general by optimizing the use of available time and money resources.
