The detail of the method of attaching the top of the concrete ‘skin’ to the existing concrete wall has been revised to reduce working at height and Hand-Arm Vibration Syndrome.
The original designed detail was to break out the existing wall to create a key for the tie in to make it water tight. The site team developed an alternative method which involved not breaking out any of the existing pier but to use a hydrophilic material which swells once in contact with concrete to create the water tight seal to the existing structure.
This reduces time working at height, removes the risk of operating equipment that could cause Hand-Arm Vibration Syndrome and saves time.
