Excavation and trench support
- What it covers
- Plan size and levels, with ground at more than one level across the section; the method on each side, whether benching, battering or shoring, with ground improvement where needed; top down excavation for soil nailing and rock bolting, lift by lift; hardstand and working platform construction to reach the top of a face; ground layers and groundwater; services and adjacent structures; plant and surcharges; staging and hold points.
- In the brief
- A cross section, long section and plan view drawn to scale from your data, with stage sketches that show each lift cut and the platform taken down with it; the ground and groundwater basis, the loads, the constraints, the categories and what the designer must return.
Ground parameters: you fill your own parameter table from your own licensed copies of the standards. Where a value is not entered, the brief directs it to the designer or to the geotechnical report.
