NORWEST HOLST Soil Engineering has started work on the ground investigation for the new Commonwealth Games Stadium in Manchester. The XVII Games will be held in the city in 2002.
Planned and supervised by geotechnical consultant Ove Arup & Partners, the 0.5M investigation for Manchester City Council will comprise a detailed evaluation of the site for the main stadium, a regional sports institute, a Metrolink extension linking the site with the city centre and a related commercial area.
The 60ha brownfield site has a history of mining and industrial use. One of the main thrusts of the work is to determine the condition and extent of shallow mine workings and to locate around 14 abandoned mine shafts under the site.
The phased investigation will include surface geophysics, rotary core drilling down to 85m with downhole camera surveys and geophysical logging, deep trial trenches and rotary probe drilling. Conventional cable percussion boring, static cone testing, plate bearing tests and insitu pressuremeter testing will also be carried out.
Geotechnical testing is being carried out at Norwest's laboratory in Leeds and contaminated testing at its ECoS environmental laboratory in Halifax.
Following the games, the track level will be lowered and the new stadium will become home to Manchester City football club, providing a fully covered, 50,000 capacity, all seater ground.
