I seek a detailed structural analysis report for a grade II listed building to evaluate the protective capabilities of an existing wall protection bollard. Specifically, the report should determine whether the current bollard better safeguards the building's integrity compared to having no fortification installed. It must also address the impact of collisions at varying speeds, detailing if impacts up to 20 mph could occur without additional harm. The analysis needs to model impacts at this threshold and above, exposing what damages may ensue. Written for non-technical readers, the document needs to clearly communicate its engineering findings regarding the barrier's function. It should consider the age and design of the structure to make scientifically-informed judgements about the fortification's role in preserving the historic building in various traffic scenarios. Professionally presented recommendations would aid planning work to sustain this listed building for generations to come. Adhering to all applicable standards, this specialized report will provide crucial insight into appropriately protecting architectural heritage.
