Este trabalho aborda a avaliação de impactos ambientais de empreendimentos rodoviários, no âmbito do licenciamento ambiental. As obras rodoviárias geram numerosos impactos ambientais e atualmente ainda existem falhas na gestão ambiental destes projetos, desde a pequena dimensão dada aos aspectos ambientais ainda na fase de planejamento da obra, perpassando por falhas nos estudos ambientais, dificuldades na previsão dos impactos e dimensionamento das medidas preventivas e mitigadoras, pelas rotinas controversas dos processos de licenciamento até o acompanhamento ambiental deficiente. Neste contexto, o presente trabalho visa propor diretrizes e procedimentos para o licenciamento ambiental de rodovias, tendo como base a análise de diferentes projetos rodoviários em licenciamento ambiental federal, localizados no Sul do país. Foram analisados os empreendimentos rodoviários BR 285 (Timbé do Sul/SC – São José dos Ausentes/RS) e BR 386 (Tabaí/RS – Estrela/RS), por meio de pesquisa qualitativa, com revisão teórica e documental. Ao final da análise foram apresentadas propostas de medidas preventivas e mitigadoras sistematizadas às etapas de instalação e operação de empreendimentos rodoviários, além dos estudos ambientais necessários ao licenciamento ambiental, de acordo com as tipologias pavimentação, implantação e duplicação de rodovias. Foram elaborados roteiros orientativos para o licenciamento de obras de apoio e para a escolha dos Programas Ambientais mais adequados às diferentes fases do projeto e diferentes tipologias de obras rodoviárias. Concluiu-se o trabalho com diretrizes básicas para os processos de licenciamento ambiental e de avaliação de impactos ambientais de rodovias. Para o processo de licenciamento: tramitação eletrônica do processo de licenciamento; licenciamento trifásico com possibilidade de fusão em duas ou uma etapa; criação de padrões para o estabelecimento de condicionantes para as licenças; participação popular em outros momentos do processo, além das audiências públicas; divulgação de impactos positivos e boas práticas adotadas; consulta aos órgãos intervenientes na fase de planejamento; exigência de manutenção de equipe de supervisão ambiental durante toda a fase de obras. Para a avaliação de impactos ambientais: criação de banco de dados nacional compartilhado com informações ambientais de empreendimentos já licenciados; elaboração de um manual de avaliação de impacto ambiental, com regras claras para a elaboração dos estudos ambientais; elaboração de manuais técnicos para temas relacionados ao licenciamento, passíveis de padronização de técnicas e metodologias; criação de roteiro metodológico com critérios para avaliação dos estudos pelos analistas ambientais; limitação do diagnóstico às variáveis ambientais com possibilidade de interagirem com o empreendimento e obrigatoriedade de um Programa de Controle Ambiental para execução durante a paralisação de obras. / This study discusses the environmental impact assessment of highways projects in the context of project licensing. Constructing highways create many environmental impacts and, nowadays, there are still flaws in environmental management of these projects, including the little importance given to environmental aspects in project planning, low quality of environmental impact statements, difficulties in impact prediction and mitigation design, common shortfalls in the project licensing process and, lastly, deficient environmental monitoring. In this context, this study aims to propose guidelines and procedures to improve the project licensing process, based on the analysis of different highways projects under government permitting process, located in southern Brazil. The following highways projects were selected: BR 285 (Timbé do Sul/SC – São José dos Ausentes/RS) and BR 386 (Tabaí/RS – Estrela/RS). The study was based on qualitative research with theoretical and documentary review. At the end of analysis, the proposals were focused on preventive and mitigating measures, considering installation and operation stages of highways projects, in addition to the main issues and statements to be considered in the licensing process, according to the different types of highways projects: paving, implementation and duplication. Some guidelines for the support project licensing were presented, as well as guidelines for the most appropriate environmental programs to be applied along different stages of the projects and to different types of highways projects. The study was completed with basic guidelines for environmental impact assessment and for project licensing of highways projects. Suggestions for project licensing: electronic processing, licensing processes in three phases with possibility of fusing into two or one, creation of standards for constraints imposed in the environmental permit, popular participation in all stages of the process, dissemination of positive impacts and best practices adopted, discussion with government agencies in highway planning moment, mandatory requirement of environmental supervision team throughout the construction phase. Suggestions for environmental impact assessment: creation of a national and shared database with environmental information from already licensed projects, development of environmental impact assessment guideline, with clear rules for the preparation of environmental impact statements, preparation of manuals on issues related to licensing with the possibility of standardization of methodologies and techniques, creation of methodological script with criteria for evaluation of studies by staff members at government agencies in charge of the licensing process, scoping on issues associated with the project (that truly matter), and mandatory requirement of a control program to run during the stoppage of works.

Performance goals for a highway system are an indication of the desired system condition, and the level of service to be provided to its users. Setting the appropriate performance goals has a significant impact on the way highway agencies conduct business. With growing needs and limited resources, the consequences of setting different levels of performance goals should be examined and compared to optimize the highway infrastructure needs at the network level. Three interacting sets of costs are typically considered for a complete economic appraisal of highway projects: construction, maintenance and road use costs. Due to the shift in focus from design-and-build mode to the repair-and-maintain mode, this study focuses on maintenance related costs and the road user cost aspects only. Maintenance and rehabilitation activities on pavement infrastructure are ongoing processes that are required for the entire road network. This suggests that for long planning horizons and geographically extensive networks, their application usually results in significant financial needs. Typically, highway agencies have based their policy decisions such as the target condition levels for the system on the budget needs for maintenance and rehabilitation actions. Since in most cases, the funding needs exceed the available budget, the required preventive and routine maintenance activities suffer or are overlooked completely. Failure to timely apply these maintenance actions cause the pavements to deteriorate more rapidly into condition states that require for more expensive rehabilitation actions during the life cycle of the pavement. Over time, a vicious cycle is instigated in which the maintenance and rehabilitation needs of the network keep increasing each year. Although most highway administrators acknowledge the fact that pavement preservation is perhaps the most effective way of using the limited budgets available, the costs associated with deferring maintenance actions is oftentimes overlooked when establishing performance goals for the system. Road user costs in the form of costs for vehicle operation have been recognized as another large component of the total transportation related costs. These costs are then arguably the most important to consider for a complete economic appraisal. Ironically, they are also often disregarded while making important policy decisions. Other road user costs such as those related to the impact of traffic congestion and detours caused by construction and maintenance activities are difficult to quantify and were not accounted for in this study. Although it is widely accepted that establishing suitable performance goal is critical for system maintenance and preservation, a framework that considers the inter-relationship between conflicting objectives of minimum maintenance and rehabilitation costs, deferred maintenance costs, and vehicle operating costs to the users does not exist. This thesis proposes a methodological framework that is aimed at assisting highway agencies with the problem of objectively analyzing policy decisions in terms of the performance goals for their highway networks that would minimize the total transport costs to the society. In a case study of the proposed framework, the highway network managed by the Texas Department of Transportation was examined for different performance goals. The results from the case study indicate that setting lower performance goals lead to savings in the M&R needs, but at the same time, they also significantly increase the exogenous costs such as deferred maintenance costs and the vehicle operating costs. / text

Highway projects are delivered in a complex environment that involves participation of diverse stakeholders with different objectives. Technological advancements have provided better tools and techniques that if incorporated can lead to effective project delivery complying with the multitude of objectives. Often the projects are cost-driven, schedule-driven, or both. Presence of ongoing traffic poses an additional challenge for the developers as it impacts the safety and comfort of both the commuters and the construction workers. A wide variety of tools, techniques and work processes are adopted across many projects depending on the project and agency requirements to make the process of project management efficient across its life-cycle. Civil Integrated Management (CIM) is a terminology that encompasses all such tools and technologies that can facilitate the process of digital project delivery and asset management. This study examines the current state of practice for CIM through surveys conducted at agency and project level. The results of these surveys are summarized to provide an understanding of the organizational and contractual issues related to CIM implementation and comprehend the process of technologies implementation and associated performance benefits at the project-level. Significant factors impacting successful life-cycle CIM utilization are elicited through the surveys and follow-up interviews and are investigated further under four main categories – Technology Implementation Planning, Model-based workflow and processes, design for construction automation and Information Management. Specific examples have been provided for each of these factors to demonstrate their utility on projects. The findings of this study will provide practitioners a list of key issues to be considered for profitable and effective implementation of the CIM technologies across a project’s life-cycle. / text
