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.
Our Client is extremely pleased at the way we, supported by Econ, have dealt with the situation. From the moment you confirmed that notifiable asbestos was present, a focused, concerted effort has been made by Econ to deal with the problem. The client was impressed at the speed in which Econ tabled a strategic proposal to the HSE to remove the asbestos, working 24/7 non-stop, to expedite the removal. The fact that the proposal, including approval by the HSE, was achieved in such a short timescale is credit to Econ. The proactive approach, while being flexible and accommodating to allow key ECR staff to work in a safe, isolated contained area, has really impressed the Network Rail team.
