Earthworks and Piling Mat
Halfway through the demolition works on phase 1 we were successfully awarded the groundworks package. This involved a 3 meter reduced dig and then installation of a piling mat in 200mm layers.
The area was a 3000m2 areas with a 1000mm deep piling mat.
We supplied an engineer to set out the levels to suit the client’s construction requirements.
We excavated three meters down across the area, transported and stockpiled the excavated material. Following this, on three sides, we constructed a 45 degree batter.
We then compacted the ground using a ride on roller, layered in 6f5 and geo-grid in 200mm layers up to 1m.
An independent engineer then carried out compaction tests on completion.
Econ was commissioned to demolish and clear a concrete footbridge spanning a four lane highway. Timing was critical to ensure that disruption to traffic and local residents was kept to a minimum.
