Abstract [en]

Mitigating emissions of carbon dioxide and other greenhouse gases is critical if we are to meet the increasing threats posed by global warming. Previous studies have shown conclusively that a substantial part of all carbon dioxide emissions comes from transportation, and that Eco-Driving principles based upon strategic, tactical, and operational decisions have the potential to reduce these emissions. However, these well-established principles have been neglected within the construction industry despite the large number of transport-related activities that attend most construction projects. This paper therefore aims to increase awareness and understanding within the industry of the potential reductions of both carbon dioxide emissions and the costs of earthmoving activities that could be achieved through the use of Eco-Driving principles. A new concept labeled ‘Eco-Hauling’, which extends the Eco-Driving concept to earthmoving, is proposed. A case study of a road project has been conducted and used to demonstrate the new concept. Discrete-event simulation is used to support the data analysis as it enables modeling of the dynamic interactions between equipment and activities of multiple different construction scenarios. The presented findings show that a combination of decisions taken from the proposed Eco-Hauling concept can enable earthmoving contractors to substantially reduce carbon dioxide emissions and costs while maintaining productivity. This study has implications for the general advancement of Eco-Driving theory, as well as for project management as it sets out a viable approach for reducing greenhouse gas emissions in construction projects.

Abstract [en]

The construction of maritime infrastructure, such as waterways and seaports, often require large-scale dredging processes. These processes are often both energy-intensive, using various fuels and emit considerable amounts of greenhouse gases such as CO2. Studies on road infrastructure have introduced and successfully implemented a number of sophisticated approaches for assessing and reducing energy use and associated CO2 emissions at a project level. However, research on maritime infrastructure construction has primarily focused on dredging at an equipment level despite the promising opportunities of assessing and reducing the climate impact at a project level. This study proposes a workflow for assessing the energy use and associated CO2 emissions of maritime infrastructure projects and demonstrates its use in a case study. The case study shows that these types of assessments are possible to conduct which also implies that alternative scenarios, such as different material uses, equipment or design choices can be compared. In practical terms project managers can benefit from such assessments and comparisons to lower the overall climate impact of their maritime infrastructure projects.

Abstract [en]

Despite many studies focusing on assessing energy use and carbon dioxide emissions in road projects, limited attention has been given to practical methods for mitigating environmental impacts at the project planning stage. Our study addresses this issue by proposing a model incorporating a step-by-step guide for calculating carbon dioxide emissions in the project. This model is practically applied to a road construction project where two major supply chain alternatives are evaluated and compared. The findings suggest that major reductions of carbon dioxide emissions can be achieved by (1) identifying and comparing a set of realistic project alternatives, and (2) conducting this at an early stage of the project planning process so that favorable alternatives can be implemented during construction.

Abstract [en]

Road projects generally begin with broad investigations and progressively advance towards more detailed and immediate issues. Road corridors, which represent rough locations of alternative road alignments, are usually identified, evaluated and compared in early planning stages. Commonly at this stage, costs estimates of the identified road alignment are made whereas their environmental impacts, such as greenhouse gas (GHG) emissions, often are insufficiently accounted for. GHG emissions caused by the construction process are frequently ignored altogether. Despite indications that benefits of decisions and measures can be considerably higher if implemented in early planning stages, much emphasis is put on later stages. Our study presents an approach for estimating project-based GHG emissions of alternative alignments in early planning stages. The findings indicate that if adopted in the planning process, the approach can support projects in reducing their GHG emissions.

Abstract [en]

On- and off-site construction activities during transport infrastructure projectsare major contributors to greenhouse gas (GHG) emissions. The SwedishTransport Administration (STA) has stated the goal of gradually reducing itsemissions from transport infrastructure projects to zero by 2050. However,current life cycle assessment (LCA)-based approaches for estimating GHGemissions are static and location-independent, and thus do not account for thedynamics of construction. Some project-based methods have been proposed,but there is little guidance and insight available to facilitate theirimplementation in real projects during project planning.This thesis aims to explore how CO2 emissions can be reduced during differentstages of the planning process for transport infrastructure. The analysis focuseson emissions during project execution, i.e. on- and off-site constructionactivities including material production, and transportation. An exploratoryresearch approach is used to develop practical CO2 reduction methods thatcould be implemented during the feasibility studies, the design stage, and theprocurement stage of the planning process. These methods and models aredeveloped and demonstrated in case studies. This is a similar to the prototypingmethod in which early drafts of a new system are developed and tested toenable further development into a finalized system. The findings show thatconsiderable CO2 reductions can be achieved if project alternatives areevaluated systematically during the planning process. Although most majordecisions are made during the early stages of the planning process, later stagesshould not be ignored because these offer opportunities to include moredefinitive project data and thereby improve the certainty of the assessments.Future research in this area should look at the entire planning process up to thestart of construction.

Abstract

In road construction, large quantities of raw materials are extracted and transported duringseveral stages of its life cycle. Consequently, processing and preparation of raw materials fordifferent purposes inevitably result in considerable amount of energy use and emissions of airpollutants. The Swedish Transportation Administration has an ambition to minimizeenvironmental impacts from transport infrastructure projects by, for instance, reducing the energyuse and emissions of greenhouse gases. This can be achieved by implementing specific strategiesand techniques during various stages throughout the life cycle of the project. In this paper aframework is proposed to manage the energy use and greenhouse gases emissions from rawmaterials extraction processes in road construction projects. A prototype is developed based onthe framework and demonstrated in a small case study.

Abstract [en]

Product and process platforms have been promoted as possible enablers of increased productivity in civil engineering. However, such platforms are traditionally applied in mass manufacturing industries where production assets are employed in continuous production of uniform products, which strongly facilitates continuous improvement. The discontinuous nature of project-based production in civil engineering restricts such possibilities. Thus, if platforms are implemented there is a need for methods capable of evaluating the performance of integrated product and production process configurations in specific projects. A possibility, explored in this paper, is to use database-driven simulation. As a case study, a configurable simulation model, based on standardized process patterns and values stored in a platform, has been developed of the production for a bridge concept. The presented results provide evidence that database-driven simulation can support efficient platform evaluation and development by integrating product and process information, even in discontinuous, project-based industrial sectors. The results specifically demonstrate that this approach can be used to evaluate effects of different configurations of construction methods on working time requirements without time-consuming updates of models.

Abstract [en]

Complex road projects, particularly near sensitive locations, often have substantial effects on humans and theenvironment caused by construction, production processes and the use phase. Before a road alignment isdetermined, several road corridors are identified and evaluated during early planning stages. Oftentimes thisevaluation focuses on impacts of the finished road whereas construction and production processes frequently areignored, risking viable corridors to be discarded before having been sufficiently evaluated. Existing IT-systemsenables modeling of relevant aspects such as road corridors, noise, pollution, production and construction, butthere is often a lack of interoperability between these systems. Interoperability problems can be faced withExtract Transform Load (ETL) tools but this has not been adequately examined regarding infrastructure projects.Our study presents a novel method for evaluating road corridors that includes production aspects, which arevisualized and analyzed in 3D. By using ETL technology to handle interoperability problems, existing tools forroad corridor planning, production planning and 3D visualization are used to demonstrate the method. Thefindings indicate that large scale production aspects related to road corridors can be modeled, analyzed andvisualized in 3D, which can benefit stakeholders in making decisions.
