Special Issue Information

Dear Colleagues,

The concepts of sustainable development and circular economy will lead the evolution in various aspects of Civil Engineering. To perform construction activities with wise use of resources and energy, and avoid bringing any harmful effect on the environment is the core. In this special issue, research articles related to sustainable development in the whole life cycle of civil infrastructures, such as planning, design, construction, maintenance, and demolition of Civil Infrastructure, are all welcome. The topics of particular interest in this special issue include (but are not limited to):

  • Sustainable material, low-carbon and resuable concrete, green material;
  • Sustanable structural design;
  • Sustanbale construction;
  • Sustanble maintenance; 
  • Management in sustainability projects,
  • Reusable conponents and structres;
  • Sustanable civil infrastructure: Bridges, railways, buldings, dams, etc.
  • Mechanics of sustanable structures and materials;
  • Sustainability assessment

Infrastructure megaprojects are increasing in size and number worldwide. Widespread shortcomings such as cost overruns, delays, litigious threats, and community opposition are now so pervasive there is a clear mandate to rethink the way we plan, deliver, and operate our infrastructure. In this context, we situate this research to understand how megaprojects can be set up for success. Data were collected from responses to a questionnaire survey, interviews, and case studies. The questionnaire was fielded by multiple agencies involved in infrastructure projects, such as engineers, construction organizations, and government delivery agencies. For qualitative insights, we conducted 30 interviews with participants from these agencies and studied cases that successfully implemented the themes identified. The results highlight the three themes with the highest impact in delivering projects successfully: (1) Improved integrated planning, business cases, and front-end engineering design; (2) efficient use of contracts; and (3) strengthening government and political engagement. This research contrasts the literature on megaproject success with data collected from questionnaires, case studies, and interviews. Collecting solutions that have solved issues effectively is an innovative aspect of our methodology, with these findings holding considerable value for ecosystem practitioners. Thus, we contribute by highlighting eight cost-effective, relevant, and efficient ways for reimagining infrastructure megaproject delivery. Full article

This study proposes a defect detection framework to improve the performance of deep learning-based detection models for ultra-high resolution (UHR) images generated by tunnel inspection systems. Most of the scanning technologies used in tunnel inspection systems generate UHR images. Defects in real-world images, on the other hand, are noticeably smaller than the image. These characteristics make simple preprocessing applications, such as downscaling, difficult due to information loss. Additionally, when a deep learning model is trained by the UHR images under the limited computational resource for training, problems may occur, including a reduction in object detection rate, unstable training, etc. To address these problems, we propose a framework that includes preprocessing and postprocessing of UHR images related to image patches rather than focusing on deep learning models. Furthermore, it includes a method for supplementing problems according to the format of the data annotation in the preprocessing process. When the proposed framework was applied to the UHR images of a tunnel, the performance of the deep learning-based defect detection model was improved by approximately 77.19 percentage points (pp). Because the proposed framework is for general UHR images, it can effectively recognize damage to general structures other than tunnels. Thus, it is necessary to verify the applicability of the defect detection framework under various conditions in future works. Full article

Due to their nature and location, ports and other maritime projects are particularly sensitive to climate change actions. Thus, when designing these types of projects, it is important to follow a methodology that incorporates climate change adaptation measures throughout the design process. This paper aims to identify the most relevant work developed in this field, along with the main knowledge gaps, through a systematic literature review process. Through a careful selection and analysis of relevant articles associated with “climate change adaptation”, “ports” and “design”, it was possible to conclude that these focused on existing infrastructures and specific case studies, on individual design aspects, on policies and economic or legal frameworks, on the perceptions around climate change or on stakeholder management. The literature review process described in this paper is part of a larger project, dedicated to the development of a practical and robust framework focused on the implementation of climate change mitigation measures in the design of new ports and other maritime projects.
