Objectives

The primary objective is to engage a qualified service provider to repair, replace, and calibrate the hospital's steam pipeline infrastructure. The project aims to restore safe, efficient steam distribution across multiple clinical and support departments while ensuring full compliance with provincial health, safety, and procurement regulations.

Scope of Work

The contractor will execute targeted repairs, component replacements, and pressure calibrations across designated hospital zones, including:

• PRV stations, laundry facilities, kitchens, greenhouses, administrative offices, theatre areas, ward blocks, calorifiers, and boiler houses.
• Replacement of specified steam fittings (isolating valves, steam traps, sight glass fittings, barrel nipples, unions, and strainers in various diameters).
• Precision calibration of Pressure Reducing Valves (PRVs) to mandated outlet pressures (200 kPa and 600 kPa), followed by issuance of official pressure test certificates.
• X-ray inspection and thorough cleaning of all welding seams to verify joint integrity.
• Pre-contract coordination requiring a two-working-day advance appointment with the maintenance supervisor to notify affected staff and schedule shutdowns.
• A mandatory minimum six-month warranty covering both labour and all supplied spare parts.

Technical Requirements

• Contractor Grading: Must hold a valid CIDB registration of grade 1ME or higher.
• Material Standards: All steam fittings and components must carry SABS/SANS approval for steam-rated applications.
• Welding Verification: Every welded joint must undergo X-ray testing and subsequent cleaning before commissioning.
• Documentation: Submission of SA-certified trade test records for personnel performing argon welding/mechanical filtering, plus verifiable completion certificates for at least one similar executed project.
• Compliance & Evaluation: Valid tax clearance, Central Supplier Database (CSD) registration, BBBEE documentation, and strict adherence to standard government contract conditions. Evaluation follows an 80/20 preferential procurement model (80 points for price, 20 points for promoting enterprises manufacturing in KwaZulu-Natal).

Skills Requirements

• Nationally certified proficiency in argon-based welding and mechanical filtration systems tailored for high-integrity steam environments.
• Hands-on expertise in steam pipeline diagnostics, component replacement, and precision pressure calibration.
• Ability to interpret technical schematics, coordinate non-destructive testing (X-ray), and generate compliant pressure test reports.
• Experience operating within live healthcare facilities, including proactive scheduling with facility management to minimise clinical service disruption.

Notes on Unusual or Complicated Terms

• CIDB 1ME: A Construction Industry Development Board classification designating contractors qualified for low-to-medium complexity mechanical engineering works, specifically covering plumbing, steam piping, and related mechanical installations.
• Argon Welding Trade Test: A formal certification verifying competency in Tungsten Inert Gas (TIG) welding, which utilises argon shielding gas to produce high-purity, leak-proof joints essential for pressurised steam infrastructure.
• PRV (Pressure Reducing Valve): A critical safety and control device that steps down incoming steam pressure to a regulated, usable level; incorrect calibration can lead to equipment failure, energy waste, or hazardous leaks.
• SABS/SANS Approval: Mandatory South African National Standards certifications confirming that materials can safely withstand steam temperatures, pressures, and thermal cycling without degradation.
• 80/20 Preference System: A public procurement scoring framework where 80% of the evaluation weight is allocated to price competitiveness, while 20% rewards specific socio-economic goals, here focused on supporting locally manufactured goods and KwaZulu-Natal-based enterprises.
