refined and launched as part of company’s major projects range.
The MP500 is the flagship of our fleet,” says Mr Whitmore. “We are
seeing a growing demand for these large struts as a cost-effective solution for
all types of major excavation.”
The hydraulically extendible strut uses modular tube sections to obtain
the required length and has a hydraulic adjustment of +/- 0.5m. The strut is
assembled in-situ, fixed to the corbels and extended and pressurised between
supports before being mechanically locked off with twin load-bearing screws.
Besides providing a clear working space within the excavation, the struts
save time thanks to the speed with which they are installed. Even the massive
struts took less than half a day to fix in place.
During the excavation phase, loads on the support structure will be
constantly monitored in real time using Groundforce’s own remote load
monitoring system. This uses load pins in the strut connectors to measure
loads and send readings via secure SMS or wireless internet links to
authorised recipients.
Each 47 m long prop was installed in less than half a day, which is far
quicker than a traditional fabricated solution. The system does not require
any mid-span support and has the added benefit of incorporating a load
monitoring system.
Merchant Square, a development by European Land and Property, is due for completion in summer 2014.

Construction begins
at Plymouth EfW
Main construction has begun at the energy from waste
incinerator plant in Devonport Dockyard, Plymouth.
GHA Livigunn were appointed by Kier Construction Ltd
as Lead Construction Designers for the Plymouth EfW
facility for client South West Devon Waste Partnership /
MVV Environment Devonport Ltd.
The start up of construction follows the completion
of pre-construction works for German energy specialist,
MVV Umwelt, and the securing of planning permission
and the Environment Permit for the plant.
The plant is designed to handle 250,000 tonnes of
waste a year, and will divert 97% of the South West
Devon Waste Partnerships residual waste from landfill,
saving around 70,000 tonnes of CO2 annually.
The main building is approximately 187 m long with a height up to 45 m. The main building and plant foundations are
piled through made ground of 25 m depth with pile loads to 4,000 kN.
The construction programme is expected to achieve a plant operational date of late 2014.
