<p>The managers of maritime port structures have to face several issues: ageing of structures, environmental risks, maintenance, adaptation to new equipments and new vessels. The assessment of structures condition is therefore a critical element to help managers to make the proper decisions to ensure a continuous exploitation and to avoid exploitation losses. This assessment is done through a diagnosis which aims to give the objective elements to make the proper choices. After a general presentation, the diagnosis issues are illustrated by the presentation of real studies on a grain dock in La Rochelle and an oil wharf in Guadeloupe Island. In each of these studies, managers’ issues are exposed, and the means and methods used to address them are presented. The conclusions of these diagnoses are then commented, with a focus on linking these specific cases to broader issues and pointing on the difficulties for the assessment and refurbishing of old structures.</p>
<p>Over the last ten years, a significant number of new underground metro infrastructures projects have been initiated worldwide. Most of these huge, strategic and costly projects are located into fast developing or dense urban areas, facing thus important challenges: interactions with existing buildings, safety risks for the population, validation of innovative construction processes, environmental issues and long-term serviceability. This paper aims to illustrate some of innovative concepts, methods and assessment devices benefit recent projects in addressing some of these important issues.</p>
