Objectives

The primary objective is to deliver comprehensive maintenance, repairs, and safety upgrades for electrical miniatures, Ring Main Units (RMUs), 11kV switchgear, and transformers across four designated municipal locations. The project must be executed within a strict four-week timeframe while ensuring operational reliability, regulatory compliance, and enhanced public safety.

Scope of Work

• Miniature/RMU Housing: Install locking mechanisms, replace faulty hardware, straighten misaligned units, remove rust, clean interiors/extiors, repaint, create a two-meter fire clearance zone, verify roof mounting bolts, and label all units using red paint according to network identifiers. Missing doors must be coordinated with municipal representatives.
• 11kV Switchgear: Tighten loose connections, replace damaged jumpers, manage oil levels and seal leaks, calibrate breaker operations, verify mechanical linkages and isolators, test interlocks, inspect cable insulation and terminations, and apply lubrication where specified.
• Transformers: Conduct visual and electrical inspections, check and top up oil levels, inspect bushings and fittings, rectify thermal faults, replace gaskets, restore earthing systems, verify metering equipment, and perform mandatory electrical tests including insulation resistance, winding resistance, and earth resistance measurements.

All activities require the deployment of a truck-mounted crane for safe lifting, transport, and handling of heavy electrical components.

Technical Requirements

• CIDB grading of EP1 or higher.
• Valid Electrical Trade Test Certificate and ORHVS certificate.
• Letter of Good Standing specifically for electrical works.
• Proof of registration with the Department of Labour as an Electrical Contractor.
• Truck-mounted crane operator certification.
• Evidence of three completed similar projects with official completion letters.
• Proof of business premises ownership or lease.
• Active registration with the Central Suppliers Database (CSD) and the Municipal Council Database.
• Current Tax Compliance Certificate.
• Completed municipal bidding declaration forms (MBD 4, MBD 8, MBD 9, and Preferential Procurement Claim Form).
• A compliant Contractor SHE (Safety, Health, and Environment) file for mandatory site induction.

Skills Requirements

• Certified expertise in medium-voltage electrical distribution systems and transformer maintenance.
• Proficiency in conducting, interpreting, and documenting high-voltage electrical and earth resistance tests.
• Operational competence with truck-mounted cranes and heavy electrical equipment handling.
• Strong knowledge of municipal safety protocols, fire clearance regulations, and earthing/bonding standards.
• Ability to accurately identify, decode, and label network infrastructure according to municipal specifications.
• Proven project management capability to deliver comparable electrical maintenance contracts within tight four-week deadlines.

Key Terminology & Clarifications

• RMU (Ring Main Unit): A compact, metal-enclosed switchgear assembly used to distribute electricity in urban and suburban power networks.
• CIDB EP1: A construction industry grading indicating foundational financial and technical capability to manage small-scale electrical installation contracts.
• ORHVS: A specialized occupational health and safety certification relevant to high-voltage electrical operations and field safety compliance.
• CSD: The national government’s Central Suppliers Database, utilized for verifying supplier legitimacy, tax compliance, and exclusion status.
• MBD Forms: Standard municipal bidding documents requiring formal declarations regarding conflicts of interest, past contractual performance, and independent bid preparation.
• SHE File: A documented safety, health, and environment management plan mandatory for contractor site induction and risk assessment.
