The reasons the company gives
The company's own explanation, not something inferred from the numbers.They were selected because they can address hard ground, existing revetments, nearby buildings, confined construction conditions and the need for early restoration, while eliminating or reducing the removal of existing revetments and the need for a temporary work platform over the river, thereby reducing vibration and noise and shortening the construction period.
