Fungurume Electrification Project

Werkman DRC, the appointed main contractor, awarded the specialist soil-resistivity testing subcontract to Mshezi Projects. The project scope covered a major HV/MV/LV electrification programme in the DRC, including substations, 11 kV feeders and kiosk substations. Mshezi’s role was the testing work package, not the overall project design or construction.

Engineering purpose

The testing work package supported the wider electrification scoping programme. Project-wide design outcomes and acceptance results are not claimed in this summary.

Appointment and delivery boundary

The assignment was a specialist testing subcontract. Overall electrification design, construction and project delivery are outside the scope described here.

Sturrock Dry Dock: soil-resistivity test record

Mshezi Projects completed soil-resistivity testing for the Sturrock Drydock Electrical project. The retained test sheet identifies an ETCR 3000B instrument and records 23 readings.

Electrode spacing recorded

1 m

Electrode depth recorded

150 mm

Temperature recorded

29 °C

Reported effective soil resistivity

555.19 Ω·m

What the record demonstrates

A documented field-testing assignment with instrument identification, test geometry and recorded results. The reported value is reproduced from the historical sheet; it is not a new design recommendation or an installed earth-resistance acceptance result.

Using the information

Any new design assessment must review the original readings, measurement geometry and site conditions. This single-spacing sheet does not establish a multi-layer soil model.

Smart Schools: fixed-spacing field records

Four school sites were tested in April 2024: Birch Acres, Mayfield, Dulcie September and Mpumelelo. The retained workbooks contain 29, 29, 71 and 89 readings respectively.

The project owner confirmed on 7 October 2026 that electrode spacing and the tester spacing setting were 1 m for all readings. The recorded values are apparent resistivity in Ω·m; test numbers are measurement identifiers, not increasing spacings.

These records document variation at a fixed spacing. They do not establish a two-layer soil model or layer thickness. Earlier model interpretations based on test numbers as spacings have been superseded. Differences between some exported readings and the workbooks remain under reconciliation.

New Burgersfort Landfill: 49 readings at 1 m spacing

The field workbook dated 25 March 2024 contains 49 apparent-resistivity readings. The owner’s clarification confirms 1 m electrode spacing and a 1 m tester setting, replacing the older spacing entry in the sheet.

Recorded range

47.75–321.60 Ω·m

Arithmetic mean

162.18 Ω·m

Median

158.30 Ω·m

The statistics describe the recorded samples; the mean is not a selected design resistivity. A depth-dependent soil model and any earthing design outcome require a separately reviewed investigation and analysis.
