Tender Summary: Repair, Replace and Calibrate Steam Pipeline

Objectives

The primary objective is to secure a qualified service provider to restore, upgrade, and optimize the hospital’s steam distribution network. The project aims to ensure a reliable, safe, and efficient steam supply to critical clinical and support departments while adhering to provincial health infrastructure and safety standards.

Scope of Work

• Comprehensive repair, replacement, and calibration of steam pipelines across designated hospital zones, including the Kitchen (PRV station), Laundry, Greenhouse, Finance Department, Theatre/Ward 7, Calorifier/Vacuum Pump area, Boiler House, and Theater.
• Supply and installation of specific steam fittings (isolating valves, steam traps, sight glasses, barrel nipples, unions, strainers, and couplers) manufactured from approved steam-grade materials.
• Conduct X-ray inspections and thorough cleaning of all welding stitches to verify structural integrity.
• Calibrate Pressure Reducing Valves (PRVs) to exactly 200 kPa and issue official pressure test certificates upon completion.
• Schedule a mandatory appointment two working days prior to the commencement of work.
• Provide a documented minimum six-month warranty for all executed work.
• Contract duration is once-off.

Technical Requirements

• Company must hold a valid CIDB Grade 1ME registration or higher.
• All supplied materials must comply with SABS, SANS, or CKS standards for pressurized steam applications.
• Submit certified copies of trade test qualifications for the specific personnel who will perform the welding and mechanical fitting work.
• Provide one verifiable reference certificate confirming successful execution and payment for a similar steam pipeline project.
• Maintain valid tax clearance, Central Supplier Database (CSD) registration, and comply with standard General and Special Conditions of Contract.
• Adhere to the 80/20 preferential procurement evaluation framework.

Skills Requirements

• Personnel must possess SAQA-accredited trade test certifications in Argon welding and/or mechanical fitting.
• Demonstrated hands-on experience in hospital or industrial steam system maintenance, repair, and calibration.
• Proficiency in pressure testing, valve calibration, and coordination with non-destructive testing (NDT/X-ray) inspectors.
• Strong understanding of occupational health and safety protocols within active healthcare facilities.

Explanation of Unusual or Complicated Terms

• CIDB Grade 1ME: A construction industry grading specifically for Mechanical Engineering works, indicating the contractor’s financial and operational capacity to handle complex mechanical installations.
• PRV (Pressure Reducing Valve): A critical safety component that regulates high-pressure steam from the boiler down to a controlled, safe operating level (specified here as 200 kPa) to prevent equipment damage or hazards.
• SABS/SANS/CKS: South African national standards and chief inspector certifications that guarantee materials meet rigorous safety, durability, and performance benchmarks for pressurized steam systems.
• 80/20 Preference Point System: A procurement evaluation model where 80% of scoring is based on price competitiveness and 20% on specific socio-economic goals (in this case, prioritizing enterprises manufacturing within KwaZulu-Natal).
• Compulsory Site Inspection: A mandatory briefing session where bidders must attend to review project specifics, access points, and site conditions. Failure to attend results in automatic disqualification.
