Objectives

The primary objective is to engage a qualified contractor to perform scheduled minor and major maintenance services on eight medical vacuum pump units across multiple clinical and utility areas at Newcastle Regional Hospital. The contract aims to ensure the reliable, safe, and regulation-compliant operation of critical medical air infrastructure through systematic preventive maintenance, component replacement, system calibration, and comprehensive documentation.

Scope of Work

The contract consists of two distinct service phases:

• Minor Service: Scheduled for August 2026
• Major Service: Scheduled for March 2027

Each phase is restricted to a one-week execution period. The scope covers inspection, cleaning, lubrication, and functional testing of specified vacuum pump models located in the POPD, Dentistry Ward block, Medical Air plant room, and Ward blocks. Core tasks include:

• Checking and replacing pump oils, filters, belts, pulleys, seals, and inline viral filters
• Verifying electrical components, motor bearings, alignment, starters, pilot lights, and safety guards
• Detecting and sealing pipe, joint, and outlet leaks
• Calibrating pressure gauges and adjusting cut-in/cut-out pressures
• Completing plant logbooks and conducting lead/lag unit cycling tests
• Cleaning plant rooms, removing rust, patching paint, and tightening electrical terminals

Contractors must develop a site-specific safety plan, comply with occupational health regulations, and submit a full service report within five working days of completion. All equipment undergoes a five-day performance test before payment is authorised.

Technical Requirements

• Full compliance with the Occupational Health and Safety Act 85 of 193, including submission of a risk assessment and PPE plan
• All materials and spare parts must be new and meet approved industry standards
• Procurement operates under a remeasurable bill of quantities; final payment reflects actual completed work, with undelivered items strictly omitted
• No variation orders will be accepted; scope is fixed
• Quoted prices must remain firm for ninety days from the closing date
• Mandatory documentation includes Central Supplier Database (CSD) registration, CIDB Grade ME certification, updated CIPC records, a valid B-BBEE status certificate or sworn affidavit, and proof of prior similar service (one executed order and a stamped completion certificate)
• A comprehensive health and safety file must be submitted to the successful bidder upon contract award
• All work must be performed exclusively during standard institutional hours (Monday to Friday, 07:30 to 16:00, excluding public holidays)

Skills and Experience Requirements

• Proven technical expertise in diagnosing, maintaining, and repairing industrial and medical vacuum pumping systems
• Hands-on experience with the specific pump models, power ratings, and pressure specifications listed in the scope
• Competence in mechanical assembly, electrical troubleshooting, pneumatic system calibration, and safety protocol implementation
• Ability to draft and enforce site-specific safety plans aligned with hospital risk assessments
• Adequate staffing and logistical capacity to execute all tasks within the strict one-week timeframe per service phase without compromising quality, safety, or hospital operations

Explanation of Unusual or Complicated Terms

• CIDB Grade ME: A Construction Industry Development Board classification that certifies a contractor’s financial turnover, technical capacity, and project management capability to undertake mechanical engineering works of varying complexity.
• Remeasurable Bill of Quantities: A pricing and payment model where the final contract value is adjusted based on the actual quantity of work completed rather than a fixed lump sum. Any tasks not delivered are financially deducted.
• No V.O.: Stands for “No Variation Orders.” This clause prohibits contractors from requesting additional payments or scope changes outside the original specification; all deviations will be rejected.
• Lead/Lag Units: An automated pump control configuration where a primary (“lead”) pump operates continuously while a secondary (“lag”) pump remains on standby. The lag unit activates automatically during peak demand or if the lead pump fails, ensuring uninterrupted service.
• Inline Viral Filters: Specialised filtration devices installed directly within vacuum or medical gas pipelines to capture airborne microorganisms, ensuring patient safety and compliance with healthcare infection-control standards.
