Objectives

The primary objective is to procure and deliver high-reliability industrial contactors specifically engineered for public street lighting infrastructure. The procurement aims to secure equipment that ensures uninterrupted, safe, and durable operation in harsh outdoor environments, thereby maintaining municipal service levels and road safety.

Scope

The scope covers the supply and direct delivery of two specific contactor models to designated City Power storage facilities. Bidders must quote on the following items:

• Item 5218: Street light contactor, 400V, 3-pole DIN rail mount, 80A per pole, AC3 duty class, 230V coil.
• Item 5219: Street light contactor, 400V, 3-pole DIN rail mount, 40A per pole, AC3 duty class, 230V coil.

Pricing must be fixed, firm, and inclusive of VAT. Quotations must include a fully completed Bill of Quantity; incomplete submissions will be deemed non-responsive. Delivery is strictly limited to City Power stores.

Technical Requirements

All supplied contactors must strictly comply with the referenced technical specification (CP_TSSPEC_016 Rev 2) and applicable national/international standards. Key technical mandates include:

• Regulatory Compliance: Conformance to SANS 60947-4-3, SANS 60947-1, SANS 60947-2, SANS 60947-4-1, IEC 61000-4 series, and VC 8036.
• Environmental Resilience: Operational temperature range of -10°C to +65°C, with a minimum IP rating of 2X to resist dust and electrical storm conditions.
• Testing & Validation: Mandatory type testing conducted by an independent accredited laboratory per SANS 60947-4-3, supported by comprehensive type test reports. Routine factory testing must also align with the same standard.
• Quality Assurance: Valid ISO 9001:2015 certification from the manufacturer or authorized distributor is compulsory.
• Documentation & Schedules: Complete submission of the prescribed technical schedules (Schedule A & B) without placeholder marks. Any deviations require written justification proving superior cost-effectiveness.
• Performance Lifespan: Equipment must guarantee a minimum operational lifespan of 20 years, with explicit declaration of rated electrical and mechanical operation cycles.

Skills & Compliance Requirements

While trade-specific skills are not explicitly listed, bidders must demonstrate strong organizational, regulatory, and procurement compliance capabilities:

• Municipal Compliance: Submission of a valid SARS PIN, active Central Supplier Database (CSD) registration, certified B-BBEE documentation, completed Municipal Bid Documents (MBD 4, 6.1, 8, 9), proof of municipal rates/tax clearance (≤90 days arrears), valid CIPC incorporation documents, and certified director/shareholder identification.
• Evaluation Framework: A minimum 80% score on the first-stage compliance assessment is required to advance. Evaluation utilizes an 80/20 preference point system (80 points for price, 20 points for socio-economic goals).
