Objectives

The primary objective is to perform comprehensive maintenance, refurbishment, and operational optimization of the existing fresh water purification plant at Greytown Hospital. The contract ensures the facility delivers safe, compliant drinking water while the hospital remains fully operational, adhering to provincial health, safety, and quality standards.

Scope of Work

The successful contractor must complete all maintenance activities within a strict four-week period from site handover. Core deliverables include:

• Supplying and filling the master filter tank with new clean filter sand.
• Draining and refilling the carbon filter tank with fresh activated carbon.
• Inspecting, servicing, and reprogramming the automated backwash system timer.
• Disassembling, cleaning, and flushing the backup filter with potable water.
• Removing and installing new filter cartridges and membrane units.
• Replacing faulty air relief valves and 1-inch gate valves on the master tank.
• Calibrating all pressure gauges, verifying inlet/outlet pressures, and clearly labeling water flow directions.
• Supplying chlorine-based Aqua tabs for post-service water disinfection.

All activities must be executed without obstructing hospital access, patient care, or ambulance routes. The site must be securely cordoned off and maintained in a clean, orderly state throughout the project.

Technical Requirements

Bidders must demonstrate full compliance with the following technical and regulatory frameworks:

• Adherence to South African Bureau of Standards (SABS/SANS) specifications and the Occupational Health and Safety Act (Regulation 85/1993).
• Compliance with the KwaZulu-Natal Provincial Administration (KZNPA) Standard Preambles and General Specifications for public sector maintenance contracts.
• Exclusive use of SABS-approved or Department of Health-endorsed materials; substitution with inferior products will trigger immediate contract cancellation.
• Provision of statutory warranty periods: three months for structural and material components, and twelve months for electrical and mechanical installations.
• Full responsibility for incidental masonry, repair of any accidental damage to hospital infrastructure, and restoration of all affected areas to their original condition at the contractor's expense.
• Submission of documented proof of prior experience executing similar water purification plant projects.

Skills and Qualifications Requirements

Contractors must possess the following competencies, certifications, and operational capabilities:

• Construction Industry Development Board (CIDB) Engineering and Building Grading 1ME/1EB for mechanical and electrical works.
• Technical proficiency in water treatment systems, including multi-stage filtration, carbon adsorption, backwashing cycles, valve replacement, and hydraulic pressure testing.
• Ability to program, troubleshoot, and maintain automated control timers for filtration and backwash sequences.
• Competence in safely handling and applying chemical water purification agents in accordance with municipal health guidelines.
• Strong project coordination skills to deliver all scope items within the four-week deadline while minimizing disruption to ongoing hospital operations.

Notes on Unusual or Complicated Terms

Grading 1ME/1EB: Refers to the CIDB grading system for Mechanical and Electrical engineering works. Level 1 denotes an entry-tier contractor authorized to execute small-scale infrastructure and maintenance projects, which is mandatory for this quotation.

Aqua Tabs: Slow-dissolving chlorine tablets used for supplementary water disinfection to eliminate pathogens and ensure microbiological safety immediately after plant maintenance.

Backwash System: An automated filtration process that temporarily reverses water flow through the filter media to dislodge accumulated sediments, restoring filtration capacity and extending media life.

KZNPA Standard Preambles: Official provincial construction contract documentation outlining standardized clauses, risk allocations, procedural workflows, and compliance requirements for all public sector building and maintenance contracts in KwaZulu-Natal.

80/20 Preference Point System: A government procurement evaluation model where 80% of the total score is awarded for competitive pricing, and 20% is allocated to specific socio-economic goals, primarily favoring verified South African-owned enterprises.
