2. Contextualization:
Under MOTRACO’s request in 2023, LES prepared the scope and carried out work on the 400 kV Arnot-Maputo Line at Tower 520, located in a small village called KwaMhlushwa, just outside Mbombela (Nelspruit). The scope included reinforcing the tower foundations and constructing a gabion wall to protect the tower against erosion, which was compromising both tower and line integrity.
After the intervention, the area experienced flash floods, and soil erosion was observed along the edges of the gabion wall. As a result, this project is being initiated to repair the issues that have emerged.
3. Scope of work:
The scope of the project entails backfilling and sloping of the soil on the edges of the existing gabion wall and planting of vegetation using hydroseeding to retain the soil from erosion and to protect against scouring along the gabion wall.
3.1 Bill of material (BOM):
| Description | Quantity | Unit |
|---|---|---|
| Surface Preparation of topsoil (80 x 45 m) – 150 mm deep | 3600 | m² |
| Imported G7 backfill material | 450 | m³ |
| Grass of Hydro Mulch Seeds | 120 | kg |
| Fertilizer | 60 | kg |
