Isle of Man Ferry Terminal

Get in touch

Project Details

Work has started on the construction of the Isle of Man Ferry Terminal at Prince’s Half-Tide Dock, Liverpool, within the Maritime Mercantile City World Heritage Site and the Stanley Dock Conservation Area. It will sit within Peel L&P’s Liverpool Waters, the £5bn regeneration scheme which is transforming 148 acres of the city’s north docks. The site clearance operation took place before Christmas 2019, with contractor John Sisk and Sons planning completion by the summer of 2021. It is predicted that the development will generate £3.2m for the economy. A link road is also under construction, with the £7m cost being funded by Liverpool City Council as part of its £500m Better Roads programme.

People

Murphy Geospatial have been appointed by Sisk to complete environmental monitoring at Liverpool Dock during site demolition, excavation, and construction work of the New Isle of Man Ferry Terminal.

A 3D monitoring station has been installed to monitor the displacement of the quay walls using prisms securely fixed to the top of the walls.

VW Piezometers have been used to monitor the pore water pressure to make sure the pressures stay within design guidelines due to the tidal effect at site.

IPIs have been used to monitor underground displacement due to works being carried out at a very close proximity to the quay’s walls which need to remain in place during and after the works.

Tilt beams have been used on the south quay wall to monitor displacement due to line of site issues which meant we could not monitor this section with 3D set up.

Process

Engage

Early engagement was key to understand exactly what the client required. A detailed discussion and a full review of the specification was critical.

Plan

Careful planning was required to execute the site works. Access was arranged to the site for the staged installation of all the monitoring equipment.

Execute

The works were executed within the allotted time frame with an agreed staged installation of the monitoring

The following was delivered to the client:

(1) The installation of the 3D automated monitoring of the quay walls.

(2) The installation of the automated Pour Pressure Piezometers.

(3) The installation of the automated In place Inclinometers (IPI).

(4) The installation of the automated Tilt Beam Monitoring.

Review

Expectations were met and the client could proceed with the demolition stage of the project.

Early engagement was key to understand exactly what the client required. A site visit before, following with a detailed discussion and a full review of the specification were critical.
