Valid tax compliance status (SARS tax pin) required.

Contract Quality Plan (Rev 0) must be submitted with the bid.

Hendrina Power Station is situated in Mpumalanga Province, approximately 30 km from both Hendrina

Township and Middelburg.

The Seven Year Dam is an unlined earth embankment constructed to collect runoff originating from the

eastern side of the power station and the adjacent coal stockyard.

Stormwater and station effluent are collected by a subsurface drainage system located east of the

chimneys and precipitator plant and are conveyed through a 1050 mm concrete pipe into an

underground culvert discharging into the dam.

Additional runoff from the stockpile area is directed via two channels into a concrete settling sump, with

overflow from the sump also feeding into the same 1050 mm pipeline.

Furthermore, a concrete pre-settling channel positioned along the security fence conveys runoff from the

southeastern section of the station to the dam inlet culvert.

The Seven Year Dam is designed to accommodate a 1:50-year flood event and has a maximum storage

capacity of approximately 18,000 m3, with a dam wall height of 3.6 m.

The structure comprises a sandy-clayey core embankment and incorporates a concrete-lined spillway,

approximately 2 m long and 300 mm high, to manage overflow during periods of high rainfall.

The spillway has an estimated maximum discharge capacity of 18,588 m3.

Mandatory: Bidders must be registered with CIDB Grade 6CE and provide a certified ECSA Professional Registration certificate for a Civil Engineer to certify as-built drawings.

Qualitative evaluation (100 points total):

• Company experience in civil construction in live operational environments (e.g., power stations, mining): 10 points. Scoring: >5 years = 10, 3-5 years = 8, 1-3 years = 4, <1 year = 0.
• Completed similar projects (dam lining, HDPE works): 30 points. Scoring: ≥6 projects = 30, 4 = 24, 2 = 12, 0 = 0. Provide letters of appointment and completion certificates.
• Construction Manager experience: 15 points. Must hold certified Bachelor's degree in Civil Engineering, Construction Management, Project Management, or related. Scoring: >5 years = 15, 3-5 = 12, 1-3 = 6, <1 = 0.

Unacceptable technical risks (zero score): Inadequate subgrade preparation, liner installation on wet/unstable surface, failed/untested weld seams, absence of anchor trenches, uncontrolled water flow, lack of geotextile protection, non-compliance with environmental regulations, inadequate quality control/documentation, use of incorrect/substandard materials.

Acceptable technical risks (score 4): Controlled residual moisture, minor differential settlement, controlled seaming variability, temporary water ingress, surface imperfections within tolerance, environmental disturbance during de-silting.
