Abstract: For decades now, sustainable efforts have been researched and implemented to reduce the building industry’ s carbon footprint and environmental impact, which presently account for around 40% of energy-related carbon emissions globally. A target reduction of 20% structural embodied carbon has a potential impact to save over 200, 000 kg CO2e per year, which is significantly higher than the potential impact of many other prescribed lifestyle reductions (driving, flying, diet changes, etc). However, little thought or engineering analysis has been made to lower the environmental impact from pre-construction stages, including the design and construction of temporary works like excavation support systems, which currently account for approximately 55% of a buildings total CO2e emissions.

This study investigates the environmental impact of Ground Force ShoreCo's MegaBrace system compared to conventional shoring systems for temporary works in construction. Life Cycle Assessment (LCA) methodology and carbon emission calculators were employed to assess the environmental burdens associated with material extraction, manufacturing, transportation, construction, and end-of-life disposal (A1-A5 modules). Key findings demonstrate that the MegaBrace system offers significant environmental advantages. Its modular design and high strength-to-weight ratio minimize material usage, reducing embodied carbon emissions. Furthermore, the system's reusability and ease of transportation contribute to lower operational emissions and reduced waste. By quantifying these environmental benefits, yielding a reduction of carbon emissions by over 50%, and considering that equipment is considered carbon neutral, this study provides valuable insights for construction professionals seeking to minimize their carbon footprint and promote sustainable construction practices.
