Workshops
Below you will find the selection of interactive workshops that will take place during the symposium. Each of the three sessions will feature four workshops running in parallel, such as case studies or technical challenges. These workshops offer the opportunity to connect with leading companies, test your expertise, and learn and collaborate with others.

Circular Ambition vs. Engineering Certainty: A Public Client’s Dilemma
In this interactive, debate-driven workshop, you will take a position, discuss options with peers, and make strategic choices. Turn sustainability goals into concrete strategies and contract decisions that can shape the future of provincial projects.
Key Topics: Circular infrastructure, Client decision-making, System transition

From Demolition to Design: Unlocking the Value of Reusable Materials
In this workshop, you will explore how reclaimed building materials can be used in new design projects. Working in small groups, you will identify the key information designers need to reuse materials, from structural performance to logistics, and map how this data can be collected during demolition. Using real project examples, you will connect your ideas to current practices such as material inventories, digital reuse platforms, and circular material chains.
Key Topics: Creative design, Data mapping, Circularity tools
Reuse
Practical methods for enabling structural reuse
In this workshop, you will work hands-on with real methods for assessing the reusability of structural components. Go with us on a live inspection of a practical case on your campus, where you will explore how we investigate existing structures, and translate findings into safe and feasible reuse applications.
Key Topics: Structural Engineering, Circular Design, Field Trip

Reuse of structural steel in practice
This workshop lets you experience what it is like to engineer and design with re-used structural steel elements. First you create a harvest map of the elements you intend to reuse from a donor structure and resolve how to demount them. Then you define an investigation plan based on realistic parameters such as the consequence class and archive information to assess the material properties. Finally you create a design using the harvested materials. Justify the choices made. You will be working in groups of 2 or 3.
Key Topics: Re-use, Structural Design, Steel

Harvesting existing structures and designing them circularly in new buildings
In this workshop, you will participate in the analysis process to determine which existing materials from a case study building can be harvested and how it’s tested, and you will design how these materials can be reused in a circular manner in a new building.
Key Topics: Structural Engineering, Steel, Dismountable construction

Circular Runway at Schiphol
In this workshop, we will guide you through our maintenance project at the Buitenveldertbaan at Schiphol Airport. Together, we will explore how projects like this can become more circular in the future. Using the Lansink Ladder, you will analyse different asset choices within the project and identify opportunities to improve circularity and sustainability in future runway projects.
Key Topics: Sustainability, Asset Management, Circular Construction
Redesign
Integral decision making for circular possibilities in redesign projects

During this workshop, you will take on the role of a contractor and explore a redesign case study, where circular possibilities ask for integral design decisions.
Key Topics: Practical, Integral, Decision Making
From traditional to circular structural design using residual materials and creativity
In this interactive workshop, you will work on a hands‑on design challenge that puts your creativity and structural thinking to the test. Unlike traditional projects, where materials are produced to fit your design, circular structural design asks you to rethink the process, starting from what is already available. You will explore how to design smart structural solutions using residual materials, requiring a shift in mindset, creativity, and technical insight. Together, we will search for clever, circular strategies to solve a real structural challenge—showing how rethinking design can open entirely new possibilities. We will learn from each other’s creativity and challenge the boundaries of what is considered a “good” design.
Key Topics: Existing materials, Creative design, Minimize waste

Circular redesign in dense urban areas
In this workshop you will design a vertical expansion of an existing building to increase residential space in dense urban areas, guided by the IMd-team.
Key Topics: Vertical expansion , Circular redesign methods, Structural engineering.
Measuring circularity
We have develped a tool enabling to measure and compare the circularity of constructions and designs unambiguously and objectively.
In this workshop, you will use our Circulator and learn how it provides insight into the circularity score of a design, allows you to objectively compare different variants, and indicates potential improvement of your circular design at a glance.
Key Topics: Structural engineers, Advisors existing structures and contract management
