Objectives

The primary objective is to restore, maintain, and optimize the hospital’s steam distribution network by repairing damaged sections, replacing faulty components, and precisely calibrating pressure-regulating equipment. This ensures uninterrupted, safe, and efficient steam supply for critical clinical, domestic, and utility departments.

Scope of Work

The contractor will execute comprehensive repairs, replacements, and calibrations across multiple hospital zones, including the kitchen, laundry, greenhouse, finance department, theatre, ward areas, boiler house, and calorifier stations. Key activities include:

• Replacing specified steam fittings such as isolating valves (15mm to 50mm), steam traps, sight glass assemblies, barrel nipples, unions, and strainers.
• Calibrating pressure-reducing valves (PRVs) to exact outlet pressures of 200 kPa and 600 kPa, followed by issuing official pressure test certificates.
• Re-plumbing broken condensate lines and installing or replacing calorifiers as indicated.
• Conducting non-destructive X-ray inspections on all welding joints, followed by thorough cleaning and quality verification.
• Coordinating with hospital maintenance supervisors two working days prior to commencement to schedule downtime and notify affected departments.

Technical Requirements

• Company must hold a minimum CIDB Grade 1ME registration.
• Valid SAQCC registration certificate must be submitted.
• All materials and fittings must be SABS/SANS/CKS approved for steam applications, with compliance certificates provided.
• Only new, unused components are acceptable; second-hand or expired products will be rejected.
• A minimum six-month warranty must cover both labour and supplied spare parts.
• Bidders must provide verifiable completion certificates for at least one previously executed and paid similar project.
• Full administrative compliance is required, including tax clearance, Central Supplier Database (CSD) registration, and completed preferential procurement claim forms.

Skills Requirements

• Lead personnel must possess an SAQA-certified trade test qualification in argon welding or mechanical fitting.
• Demonstrated expertise in high-pressure steam pipeline systems, including precise valve calibration and condensate line reconstruction.
• Proficiency in coordinating and interpreting X-ray weld inspection reports to ensure structural integrity.
• Strong project management capabilities to execute work within hospital operational constraints while maintaining strict safety and compliance standards.

Explanation of Unusual or Complicated Terms

• CIDB Grade 1ME: The highest Construction Industry Development Board classification for Mechanical Engineering works, signifying the contractor’s proven capacity to handle complex, large-scale industrial projects.
• SAQCC Registration: Mandatory licensing by the South African Qualifications Certification Committee, verifying that the company legally qualifies to perform construction and engineering services.
• Argon Welding Trade Test: A specialized welding process using inert argon gas shielding, essential for creating leak-proof, corrosion-resistant joints in stainless steel steam pipes. Requires formal national certification.
• X-Ray Weld Inspection: A non-destructive testing method used to detect internal flaws in welded seams without damaging the pipeline, ensuring compliance with high-pressure safety standards.
• PRV Calibration: The precise adjustment of pressure-reducing valves to deliver steam at exact kilopascal thresholds, preventing equipment damage and ensuring consistent thermal output across departments.
• 80/20 Preference Point System: A public procurement evaluation model allocating 80 points to competitive pricing and 20 points to socio-economic goals, specifically favouring enterprises manufacturing within KwaZulu-Natal.
