Abstract: Last few years the hindrance, accidents, pollution and other negative side effects of construction projects and namely construction transport have become an issue particularly in urban areas across Europe such as in London, and in the Netherlands as well, including the cities of Utrecht, Rotterdam and Amsterdam. Municipalities have issued new legislation and stricter conditions for vehicles to be able to access cities and city centres in particular and accessibility of older and polluting vehicles. Considerate clients, public as well private, have started developing tender policies to encourage contractors to reduce the environmental impact of construction projects. Contractors and third party logistics providers have started applying consolidation centres. These developments have shown considerable reductions of number of vehicles needed to deliver goods and to transport workers to site. In addition these developments have led to increased transport efficiency, labour productivity and cost reductions on site as well as down the supply chain. Besides these developments have led to increased innovations in the field of logistics planning software, use of ICT , and handling hardware and equipment. This paper gives an overview of current developments and applications in the field of construction logistics in the Netherlands, and in a few project cases in particular. Those cases are underway as part of an ongoing applied research project and studied by using an ethnographic participative action research approach. The case findings and project results show initial advantages how the projects, the firms involved and the environment can profit from the advancement of logistics management leading to reduced environmental impact and increased efficiencies of construction transport.
Construction and Demolition Waste (CDW) is the main driver of resource consumption and waste generation in Europe. Although most European countries achieved 70% recovery rate of CDW, the majority is used for backfilling. Therefore, opportunities for Circular Economy (CE) practices in CDW management are underexploited. This research identifies the innovative practices, barriers, and enablers for developing tailored-made designs of Urban Resource Centre (URC) for managing CDWs in four European cities namely Riga, Tartu, Kavala, and Barcelona. Qualitative methods using multiple case studies were used to draw generalizations from cases. Data was collected from reports and interviews with different stakeholders, and a validation workshop for designing URC of each city. Current innovative practices include recycling and upcycling of CDWs; use of green points, exchange platforms, and waste management apps; repair cafés; selective demolition; and (pilot) initiatives on resource centers that function as material exchange point, recycling center, workstation for repair and creative ideas, and prototyping hub, among others. The identified barriers and enablers can be categorized as governmental, market, and individual factors. First, local governments (municipalities) play a key role for facilitating CDW management via both support such as provision of subsidies, green procurement, and mandatory waste sorting, and through strict regulatory requirements. Second, URCs must be locally rooted with inclusion of citizens, grass roots initiatives, and schools/universities to increase community acceptance, awareness, and education on CDW management. Third, partnerships with local stakeholders, such as repair cafes, waste management companies, and local NGOs, is needed to operate the URCs both in short- and long-terms. And fourth, the creation of niche markets such as linking localism (e.g. locally crafted CE stores) and supplying to businesses in need of CDWs, can support the operation of URCs. The identified barriers and enablers can help further improve the design of URCs for each city.

The Dutch Environmental Vision and Mobility Vision 2050 promote climate-neutral urban growth around public transport stations, envisioning them as vibrant hubs for mobility, community, and economy. However, redevelopment often increases construction, a major CO₂ contributor. Dutch practice-led projects like 'Carbon Based Urbanism', 'MooiNL - Practical guide to urban node development', and 'Paris Proof Stations' explore integrating spatial and environmental requirements through design. Design Professionals seek collaborative methods and tools to better understand how can carbon knowledge and skills be effectively integrated into station area development projects, in architecture and urban design approaches. Redeveloping mobility hubs requires multi-stakeholder negotiations involving city planners, developers, and railway managers. Designers act as facilitators of the process, enabling urban and decarbonization transitions. CARB-HUB explores how co-creation methods can help spatial design processes balance mobility, attractiveness, and carbon neutrality across multiple stakeholders. The key outputs are: 1- Serious Game for Co-Creation, which introduces an assessment method for evaluating the potential of station locations, referred to as the 4P value framework. 2-Design Toolkit for Decarbonization, featuring a set of Key Performance Indicators (KPIs) to guide sustainable development. 3- Research Bid for the DUT–Driving Urban Transitions Program, focusing on the 15-minute City Transition Pathway. 4- Collaborative Network dedicated to promoting a low-carbon design approach. The 4P value framework offers a comprehensive method for assessing the redevelopment potential of station areas, focusing on four key dimensions: People, which considers user experience and accessibility; Position, which examines the station's role within the broader transport network; Place-making, which looks at how well the station integrates into its surrounding urban environment; and Planet, which addresses decarbonization and climate adaptation. CARB-HUB uses real cases of Dutch stations in transition as testbeds. By translating abstract environmental goals into tangible spatial solutions, CARB-HUB enables scenario-based planning, engaging designers, policymakers, infrastructure managers, and environmental advocates.
