Descriptions
The new and improved Geosense In-place Inclinometer has a 20% smaller diameter sensor, is 38% lighter with the same trusted performance.
The Sensor is combined with the rod and with integrated connectors for speedy tool-free install.
It consists of a series of wheeled sensors of varying lengths, connected together and set at the required depths within the inclinometer casing.
This rigid rod system (IPI-RR) has specially designed connections which link the sensors, allowing them to move independently to each other without influencing those above or below. This provides a profile of displacement over the complete length of the installation. The sensor gauge lengths can be varied to suit individual requirements. For example, more sensors can be concentrated in areas where movement is expected.
The wire rope system (IPI-WR) is designed for use where only specific zones are of interest rather than the profile of the entire borehole. In this system, sensors are linked with a wire rope rather than rods.
In both systems, a digital BUS runs the length of the chain of connected sensors eliminating the need for a separate cable for each sensor. A specially designed signal cable connection not only eliminates the need for external cables and connectors but ensures highly watertight joints and full EMC screening.
In-place inclinometers are typically used for safety critical applications where ‘real time’ monitoring and early warning is required in order to protect life and valuable assets. They are easy to automate using data acquisition systems and GeoAxiom Vista software.

Merseyside Dock
Isle of Man Ferry Terminal, Merseyside Dock
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.

Manjung Iron Ore Handling Plant
Vale Malaysia Minerals Sdn Bhd a subsidiary of Brazilian metals and mining giant VALE S.A the world’s largest iron ore exporter is developing a
$5.6 billion iron ore distribution centre in Manjung, Perak, Malaysia. The project includes a deep water jetty and onshore stockyard.
The centre in Manjung will receive iron ore from Brazil for blending purposes and later be shipped to customers throughout the Asia Pacific region.
Construction of the facility will be in three phases. The first phase is to start with operations in June 2014 and will have a throughput capacity of 60 million dry weight tonnes per year (mty).
As part of the construction work, Vale awarded a STG30 million (RM148.5 million) contract for piling and groundworks to Keller Sdn Bhd, a Malaysian subsidiary of UK’s Keller Group plc. The instrumentation and monitoring during construction is being carried out by Getec, Keller’s specialist instrumentation division.

Tel Aviv Metro Red Line – Arlozorov Station
Arlosorov Station is the fifth in a series of ten underground stations on the 23km Red Line, Tel Aviv’s new light-rail system.
An underground building of reinforced concrete, flat-slab construction, comprising of water-tight diaphragm ‘outer-box’ walls, to facilitate temporary works requirements during ground excavation, allowing for the construction of the main station inner box.
The outer box has a series of temporary inner struts and waling beams to support its walls during the construction process, requiring careful detailing and construction sequence coordination. The high water-level provide large buoyancy forces on the base of the structure, necessitating a reinforced concrete ‘plug slab’ at the base of the station, restrained by tension piles.
