Objectives

The primary objective is to execute comprehensive after-service repairs and preventative maintenance on three standby generators (No. 1, 2, and 3) at the Natalia Building. This ensures continuous operational readiness, particularly during power failures, while maintaining strict adherence to occupational health, safety, and provincial health department standards.

Scope of Work

The contractor will perform targeted mechanical repairs and servicing on the specified generators. The scope encompasses:

• Conducting oil sampling and industrial wear-check analysis through an ISO-registered laboratory.
• Replacing two oil filters and clearly marking service dates.
• Repairing two leaking injector pumps.
• Repairing or replacing two rear main crankshaft seals.
• Replacing three water jacket heaters.
• Removing all obsolete spare parts and formally handing them over to the Artisan Foreman, with submission documented alongside invoices.
• Preparing and submitting a comprehensive project safety file.

All activities must comply with the Occupational Health and Safety Act 85/1993 and Department of Health standard preambles. The work area requires daily clearance of rubble. A one-week lead time for material procurement commences only upon issuance of a Site Handover Certificate. The contract is structured as a once-off engagement.

Technical Requirements

• CIDB Grading: Minimum 1ME (Mechanical Engineering) certification.
• Regulatory Compliance: Valid registration with the Department of Labour (Letter of Good Standing), active Central Supplier Database (CSD) registration, and SARS tax clearance.
• Qualifications: Certified copy of a Trade Test Certificate for Diesel Mechanics.
• Experience: Documentary proof of successfully completing at least one similar generator repair or maintenance project (Award Letter and Completion Certificate).
• Materials & Standards: All components must be SABS-approved or carry equivalent BS/DIN marks. Pre-installation approval from the maintenance supervisor is mandatory. Oil analysis reports must originate from an ISO-registered entity.
• Warranty: Three-calendar-month guarantee against defective materials, equipment, and workmanship from the servicing completion date.
• Documentation: Fully priced Bills of Quantities, completed Standard Bidding Document (SBD) compliance forms, and clear identification of subcontractors or accredited local spare parts agents.

Skills Requirements

• All repair and maintenance activities must be executed by a Trade Tested Diesel Mechanic.
• Bidders must demonstrate sufficient staffing capacity to complete the scope within the stipulated timeframe following site handover.
• Proven technical expertise in diesel generator systems and mechanical plant maintenance is mandatory.

Notes on Unusual or Complicated Terms

• After Service Repairs: Refers to corrective and preventative maintenance performed post-installation or post-commissioning to restore optimal functionality, address wear-related faults, and extend equipment lifespan.
• CIDB 1ME Grading: A Construction Industry Development Board classification indicating minimum competency in mechanical engineering works, ensuring contractors possess the technical capability for specialized plant, equipment, and generator repairs.
• 80/20 Preference Point System: A South African public procurement evaluation model where 80% of scoring is allocated to competitive pricing and 20% to transformation goals (specifically, full ownership by historically disadvantaged persons).
• Site Handover Certificate: An official administrative document issued by the employer that formally transfers site access, confirms readiness for work, and triggers the contractor's procurement lead time.
