Tender Summary

Objectives

The primary objective is to perform scheduled maintenance and servicing on backup generators across multiple water infrastructure sites in Richards Bay. The goal is to ensure uninterrupted electricity supply during grid outages, thereby maintaining pump operations and preventing community water shortages. Regular servicing aims to mitigate unexpected engine failures and extend equipment lifespan.

Scope of Work

The contract encompasses comprehensive maintenance of seven generator installations located at various pump stations and reservoirs within the City of uMhlathuze. Core deliverables include:

• Annual servicing aligned with manufacturer guidelines.
• Replacement of lubricating oil, fuel filters, coolant filters, air filters, and coolant.
• Inspection and replacement of the air intake system, intercooler, and cooling fan.
• Testing of battery systems, supply and installation of two specific battery models, and inspection/replacement of battery chargers.
• Post-service unit cleaning and provision of specified diesel volumes where applicable.
• Issuance of official service certificates for municipal maintenance records.
• Submission of a completion report detailing routine maintenance recommendations.

Technical Requirements

All maintenance activities must strictly adhere to original equipment manufacturer specifications. Technicians are required to disconnect all power sources prior to commencing work and must obtain explicit supervisor authorization before interrupting or isolating any plant operations. Upon completion, the contractor must verify that each generator operates efficiently and sign a site-specific permit to work. Strict occupational health and safety protocols apply, mandating the use of personal protective equipment (reflective vests, safety goggles, dust masks, and ear protection) and maintaining environmental housekeeping standards throughout the project.

Skills and Qualification Requirements

Bidders must deploy accredited technicians with specialized knowledge of generator engines. Mandatory qualifications and documentation include:

• CIDB grading certificates (1EP and 1ME or higher). CIDB refers to the Construction Industry Development Board, which regulates construction-related contractors in South Africa.
• Professional certification for electrical/mechanical technicians or diesel mechanics.
• A mechanical or electrical Letter of Good Standing.
• Four traceable purchase orders and completion letters proving prior experience servicing generators of at least 100 kVA.
• Two completed generator service checklists bearing company letterheads and official stamps from previous engagements.
• A detailed method statement outlining execution procedures.

Attendance at the compulsory site meeting is strictly enforced; quotations submitted by absent representatives will be automatically disqualified.

Key Terms and Conditions

Several municipal procurement rules govern this tender. Suppliers must be registered with the Central Supplier Database (CSD), a national repository used by government entities to verify supplier legitimacy and compliance. The evaluation utilizes an 80:20 preferential procurement system, allocating 80% of points on price and 20% on designated transformation goals, including ownership by women, youth, persons with disabilities, and residents of rural areas or townships. Any price amendments must be manually signed by the bidder; unsigned alterations will invalidate the submission. Quotations must be completed in black ink, and failure to provide compulsory compliance documents (tax clearance, compensation fund standing, and safety health environment files) results in immediate disqualification. ATS refers to Automatic Transfer Switches, devices that automatically switch power supply from the main grid to the backup generator during outages.
