Tender Summary: Ndondwane Pump Station Mechanical & Electrical Installation

Objectives

The primary objective is to urgently refurbish and secure the vandalised Ndondwane Pump Station to restore a reliable, sustainable treated water supply to the community in Ward 32. The project aims to eliminate the current dependency on emergency water tankers and re-establish gravity-fed distribution through the existing municipal reticulation network.

Scope of Work

The contract encompasses all mechanical and electrical installation works required to rehabilitate the pump station. The successful supplier must provide all materials, consumables, labour, and equipment, except for the pumps, which are supplied free of charge by the municipality. Key deliverables include:

• Supply and installation of two 22kW control panels
• Reinstatement of 16mm² x 4 Core Armoured Supply Cable and 10mm² x 4 Core Trailing Cable
• Installation of pressure sensors, pressure gauge, and hot-dip galvanized mild steel cable trunking
• Installation of internal and external lighting
• Fabrication and installation of an access door with burglar guards
• Fabrication and installation of pipework including all fittings
• Commissioning, handover, and provision of a Certificate of Compliance (COC)

Attendance at a compulsory site meeting is mandatory; quotations from absent bidders will be automatically disqualified. No price variations or alterations will be accepted unless explicitly signed by the bidder.

Technical Requirements

Bidders must comply with stringent technical, safety, and administrative standards:

• Safety & Site Compliance: Contractors must submit a comprehensive safety file, wear appropriate PPE (including reflective vests), obtain signed permits to work, and maintain strict environmental and housekeeping standards. Plant operations cannot be isolated without supervisor authorisation.
• Administrative Documentation: Suppliers must be registered on the Central Suppliers Database (CSD) and the Municipal Council Database. Required submissions include a Tax Compliance Certificate, Letter of Good Standing with the Compensation Fund, proof of business premises, and standard municipal bidding forms (MBD 4, 8, and 9).
• Experience Verification: Bidders must attach three traceable, signed completion letters for previous electrical panel installations and three for fabrication/pipework projects. These form part of the technical evaluation.
• Quotation Rules: All forms must be completed in black ink. Any price changes require manual signature confirmation. Incomplete or unsigned submissions will result in disqualification.

Skills Requirements

The project requires highly skilled trades personnel with verified credentials:

• Trade Certifications: Valid trade test certificates are mandatory for electricians, boilermakers, welders, and fitters.
• Accreditation: Personnel must hold relevant industry accreditation where applicable (e.g., SITA training).
• Site Induction: All workers must complete municipal safety inductions and adhere to risk management protocols.
• Proven Track Record: Demonstrated experience through the required completion letters ensures competency in similar mechanical and electrical rehabilitation projects.

Explanation of Unusual or Complicated Terms

• Free Issue Equipment: The municipality supplies the two pumps directly. The contractor is solely responsible for their physical installation, wiring, and commissioning, not procurement or cost.
• CSD Registration: The Central Suppliers Database is a mandatory national portal for all public sector procurement. Non-registration automatically disqualifies a bidder.
• CIBD Certificate: Issued by the Construction Industry Development Board, this certifies the contractor’s grading and financial/technical capacity to execute construction-related works. Grading 1ME and 1EP or higher is required.
• Preferential Procurement (80:20 System): A scoring model where 80 points are awarded for price competitiveness and 20 points for socio-economic development goals (e.g., black ownership, female/youth/disabled management, rural/township residence). Claimants must submit certified proof.
• MBD Forms: Standardised municipal bidding documents covering declarations of interest, past supply chain misconduct, and independent bid determination to ensure transparency, prevent collusion, and enforce ethical procurement practices.
