Installation Procedure

Making the Site Ready for Installation Works

Prior to any installation works taking place, operatives would make the site ready to receive the proposed shore elements of the project. This would entail setting out the position of the bridge head and shore frame.This would entail setting out the position., work can begin on access for piling and lifting plant.Plant access to the river bank directly to the work site. All removed articles will be reinstated once all installation works have been completed.

Installation of the Pontoon Facility

The pontoon units will be delivered to site, fully assembled, by articulated lorry. This method minimises the time on site and impact on local operations. Delivery of the pontoons and the required lifting operations will be coordinated by the site supervisor. The pontoon units will be installed under the supervision of experienced site supervisor. The pontoons will be lifted into the water from the proposed lifting location, via an onsite crane.

Once in the water, the units will be moved into position allowing the piling contractor to use the pile guides attached to the pontoon frames as locating guides for the pile locations. Once piling operations have been complete and the pontoons are securely moored, the access gangway will be lifted from the worksite and positioned between the shore frame and bridge landing pontoon. With this in position, it will be secured at the shore end while ensuring it is tracking correctly on the pontoon.
