The
Department of Defence is proposing to dispose of its former naval stores
depot at Ermington. The site is to be developed for residential use
as a high quality precinct yielding up to 700 dwellings and parkland.
Works to progress this plan are to stabilise the underlying soft fill
materials and raise the level of the site above the 1:100 year flood
requirements.
The contract was for the supply, installation and maintenance of ground
monitoring equipment to enable engineering analysis to determine whether
the Construction Works are achieving the designed site filling and stabilisation
objectives.
The instrumentation layout consisted of five individual sites each containing
three double piezometer boreholes and three extensometer boreholes.
These instruments were connected via trenched cable to five monitoring
stations. Each station consists of a VW Logger and an Extensometer Logger
housed in a steel enclosure and powered by a solar panel.
Geotechnical Systems were responsible for the instrument manufacture
and supply, site supervision, control of drilling and trenching subcontractors,
client and main contractor liaison and commissioning.
The
contract was completed successfully on time and on budget with the minimum
of interference with the main contract. The monitoring system is now
operational. |
