This re-advertised contract forms part of a larger water infrastructure project near the Loskop Dam area. The works include construction of approximately 5.4km of 22kV Hare line and 14km of 22kV Mink line running alongside the existing Dennilton line, which will be replaced once Eskom has transferred customers to the new route. Scope items include excavation and planting of poles to Eskom and Spanplan drawings, assembly of MV structures and stays, conductor stringing, installation of transformers, surge arresters, labelling, earthing systems, LV cable laying and terminations, recloser and CT/VT metering units at both pump stations, pre-commissioning and equipment testing, and dismantling of the redundant Dennilton line. Completion is handed over to Eskom, which must issue a completion certificate.
The contract is a re-measurement arrangement governed by the GCC 2015 (3rd Edition) and SANS 1200 standards, with a 180-calendar-day practical completion period, a 365-day defects liability period, a 5% fixed performance guarantee plus 10% retention, and a penalty of R20,000 per day for delay. Tenderers must be accredited Eskom service providers and registered on the Eskom DT Web site, hold a valid CIDB grading of 7EP or higher, and have a minimum of R10 million professional indemnity and public liability insurance. Evaluation follows an 80/20 price and preference system, with functionality thresholds of 66 out of 100 points covering organising and staffing, plant and equipment (including a truck-mounted crane, rock drill truck, TLB and bakkies), and experience in comparable MV/LV reticulation projects. Key personnel must hold ECSA registration, SACPCMP health and safety officer status, and Eskom MV/LV training certificates where applicable. Tender documents are downloadable free of charge from eTenders, a non-compulsory briefing takes place on 22 October 2026, and submissions close at 12:00 on 2 November 2026 at the Nkangala DM tender box in Middelburg. Tenders remain valid for 120 days.
For contractors, this opportunity offers a substantial bulk electrical contract in a rural water infrastructure programme with a well-defined scope, detailed Eskom drawings and standard specifications. It is especially relevant for firms with established MV overhead line experience, Eskom accreditation and an existing plant fleet. Local enterprises within Nkangala District, and businesses meeting the specific goal criteria (black, women, youth, disability-owned or military veteran enterprises), can benefit from preference points. Bidders should prepare CSD reports, a valid SARS tax compliance PIN, bank confirmation, municipal account statements, and proof of professional indemnity cover.
Eskom-accredited electrical contractors with proven MV overhead line experience, CIDB grading 7EP or higher, and a valid tax clearance and CSD registration. Suitable firms include those with cranes, rock drilling trucks, TLBs and trained line crews, as well as joint ventures combining civil and electrical capacity. Local Nkangala District businesses and enterprises owned by black, women, youth, disabled or military veteran entrepreneurs may also benefit from preference points. Smaller electrical firms should consider subcontracting or joint venture arrangements, given the scale and R10 million insurance requirements.
