Hamburg’s U5 Subway Line: Tendering and Award Criteria for Sustainability Requirements

The decarbonisation of major infrastructure projects is a key factor in achieving climate targets in the transport sector. Public clients can contribute to this by incorporating sustainability criteria into their tendering and award conditions. Such measures can create incentives to use lower-emission building materials and construction methods, whilst also improving transparency in supply chains. Using the example of Hamburg’s U5 subway line, this article shows how sustainability can be integrated into procurement processes step by step, in compliance with public procurement law. The focus is on criteria for reducing greenhouse gas emissions (GHG emissions) and for addressing environmental and social risks, particularly within steel and concrete supply chains.

From Spoil to Construction Material: Turning Soil and Rock Into a Sustainable Cement Substitute

Every year, millions of tonnes of excavated material are generated during tunnelling and underground construction projects. To date, most of this material has been disposed of in landfill sites without further use. The interdisciplinary research project Geo-BAB is investigating how such clay mineral-rich materials can be transformed into a low-CO 2 alternative to conventional cement through thermal treatment and chemical activation.
