Task Group 6.6
Carbon Footprint of Bridge and Infrastructure Construction Projects Mission Statement/Objectives The construction of bridges, tunnels, rail and roads inherently produces a carbon footprint due to the production of materials and site related activities. Moreover, most construction projects directly impact traffic flow, as many countries prioritize widening infrastructure or replacing bridges while traffic continues. This component of construction related emissions can often surpass the embodied carbon value. We aim to better understand the overall carbon footprint of bridge and infrastructure construction to provide accurate data during the optioneering stage and ultimately select the best (i.e. most cost effective and sustainable) option in the future. Scope & Limitation TG 6.6 shall first gather available workflows, tools and databases from around the globe, evaluating their practical value, identifying possible contradictions and gaps, and providing recommendations. This includes analyzing initiatives such as “Net Zero Bridges” and other construction impact frameworks. The members of the task group will apply the various recommended workflows, tools and datasets to real projects and discuss their findings. The application of BIM will play an important role in accurately connecting material volumes with unit CO2 values and automating the process during the option selection phase. Based on these findings, the task group will develop recommendations on how to evaluate the carbon footprint of bridge construction incl. the impact of traffic interference. From the results of the cases studies, the task group will further recommend specific materials and construction techniques that positively impact the carbon footprint. Expected Project Output
