The project involved the construction of a concrete arch over a live rail network which provided some unique challenges and additional safety considerations. Significant planning and effort was required to safely complete the project while accommodating regular interruptions of FMG trains. Full credit is awarded to the entire team and their ability to consider, plan and deliver the project safely. The project was delivered through the COVID-19 lockdown, a significant component of the design was delivered by our team in their home offices. The increased communication between FMG, Centrals and BGER was beneficial to the design process and has been adopted by BGER moving beyond the project.
