Objectives

The primary objective is to engage a qualified contractor to perform comprehensive maintenance, servicing, testing, and compliance verification of the medical vacuum plant room and its associated distribution network at Gamalakhe Community Health Centre. The service ensures uninterrupted, safe, and clinically compliant vacuum supply for hospital operations while meeting provincial health department engineering standards.

Scope of Work

The contract requires complete servicing of the existing vacuum infrastructure within a strict fourteen-day completion window. Key deliverables include:

• Execution of a twelve-month preventive maintenance schedule for central plant equipment.
• Servicing of two vacuum pumps, including oil drainage and certified disposal.
• Inspection and servicing of vacuum piping, pressure switches, receiver tanks, and gauges.
• Cleaning, checking, and replacement of anti-bacterial filter cartridges.
• KPA pressure testing and condition reporting for forty-five vacuum point connections.
• Inspection of vacuum bottle trap seals and submission of a comprehensive after-service fault report.
• Completion of mandatory leakage testing documentation and handover of all decommissioned spare parts to the facility workshop.

Technical Requirements

All works must strictly adhere to the National Building Regulations (SABS 0400), the Occupational Health and Safety Act (85 of 1993), and the Department of Health’s Standard Preambles. Core technical mandates include:

• Maintenance of two reciprocating, air-cooled, silent-running vacuum pumps linked to a standby generator, operating within a 20–50 kPa absolute range.
• Use of an all-welded receiver tank painted yellow, fitted with a 100 kPa rupture disc and resilient pipe connections.
• Exhaust gases must be piped externally, positioned at least six metres away from building air intakes.
• All materials must hold SABS/SANS approval and receive prior clearance from the maintenance supervisor.
• Strict prohibition on unauthorised use of jackhammers or cutting of electrical/network cables without Maintenance Manager approval.
• Mandatory execution of a one-hour leakage test, where system pressure increase must not exceed 10 kPa.
• Continuous site housekeeping, protection of existing furnishings, and compliance with environmental waste disposal protocols.

Skills and Qualification Requirements

Bidders must demonstrate proven capability and regulatory compliance:

• Valid Construction Industry Development Board (CIDB) grading of ME1.
• Certified proof that all pipe fitters possess documented knowledge and experience in medical gas and vacuum installations, supported by relevant competency cards.
• Appointment of a qualified electrician responsible for regular inspection of electrical equipment and monthly testing of earth leakage units.
• Demonstrated capacity to manage skilled labour, enforce occupational health and safety plans, and assume full legal responsibility as an employer under the Compensation for Occupational Injuries and Diseases Act.
• Submission of valid tax clearance, Central Supplier Database (CSD) registration, and Broad-Based Black Economic Empowerment (B-BBEE) documentation.

Explanation of Unusual or Complicated Terms

• Permit to Work System: A formal authorisation protocol required before any technician isolates, services, or alters medical gas/vacuum infrastructure. It prevents accidental supply disruptions and ensures coordinated safety measures across clinical and engineering teams.
• SPECIFICATION MG: The provincial Department of Health’s standardized technical manual governing the design, installation, testing, and commissioning of medical gas and vacuum pipelines. It dictates precise engineering tolerances, material grades, and procedural workflows.
• Leakage Test (Form B4): A critical performance validation requiring the vacuum system to maintain stability over a one-hour isolated period. Exceeding a 10 kPa pressure variance indicates pipeline faults or seal failures, necessitating immediate rectification before clinical handover.
• Section 37(2) OHS Act Agreement: A statutory declaration transferring full health and safety liability to the contractor. It legally classifies the contractor as the principal employer on-site, mandating independent risk management, incident reporting, and worker indemnification.
