May Gurney has spent part of one of the harshest winters on record carrying out investigation work across a site in Eastlands, Manchester using a variety of techniques.
The site is part of the Sportcity complex, and is close to Manchester City’s football stadium.
“It is quite a varied project,” says May Gurney site investigation manager Ben Armstrong, “We’ve used most techniques across the site.”
These include the use of trial pits, cable percussion bored holes and rotary drilled holes.
In a site investigation regime designed by the client’s consultant Arup, the May Gurney team used its plant fleet to install 30 holes. Ten holes were bored using cable rigs drilling to depths of between 12m and 18m. The remaining 20 were taken on to a greater depth by the rotary rigs.
“The site itself is currently car parking and is split into three main areas,” explains Armstrong. “One of the biggest issues we had was the fact that we had to get mobilised and on site quickly. We were given very little notice to get the three cable percussion and four rotary drilling rigs, as well as the assorted excavators and smaller pieces of plant, to site.”
The team used a series of trial pits to locate and investigate the backfilling of buildings and that of the branch of an infilled canal that crossed it.
