Objectives

The primary objective is to secure professional major servicing and maintenance for eleven ultra-low temperature (-40°C) refrigeration units distributed across clinical, pharmacy, and administrative departments at Mosvold Hospital. The service aims to ensure reliable equipment performance, maintain precise temperature stability for critical medical and biological storage, extend asset lifespan, and comply with provincial health department operational and safety standards.

Scope of Work

The contractor will execute comprehensive annual major servicing on all specified units. Core activities include:

• Internal inspection and cleaning using approved hospital-grade disinfectants, including removal of ice build-up, shelving, baskets, and thorough gasket cleaning.
• Condenser and evaporator coil cleaning, fan motor inspection, and verification of unrestricted airflow.
• Full refrigeration system assessment covering compressors, refrigerant pressure and levels, capillary tubes, expansion systems, and pipe insulation integrity.
• Electrical control panel inspection, wiring checks, terminal tightening, and circuit protection testing.
• Precision temperature controller calibration and verification using calibrated data loggers to ensure accurate -40°C operation and rapid recovery after door openings.
• Testing of integrated alarm and monitoring systems (high/low temperature, power failure, and door-open alarms).
• Door hinge, handle, and rubber gasket inspection with replacement of degraded seals to guarantee airtight closure.
• Functional performance testing to confirm target temperature achievement, compressor cut-in/cut-out cycles, and multi-hour stability monitoring.

All work must be performed within designated hospital operating hours (07:00–16:00), ensuring zero disruption to patient care or staff operations. Contractors are responsible for safe waste disposal at authorized sites and must adhere strictly to occupational health and safety regulations.

Technical Requirements

Bidders must submit a fully compliant quotation meeting the following mandatory criteria:

• Valid CIDB registration specifically classified for refrigeration works.
• Certified proof of qualification as a refrigerator technician (issued within the last six months).
• Documentation verifying approval as an authorized agent for Minus 40°C freezer servicing.
• Public liability insurance coverage of at least R5,000,000.
• Valid gas handling certificate.
• Current SARS tax clearance certificate and active Central Suppliers Database (CSD) registration.
• Letter of good standing and three copies of completion certificates for comparable services.
• Signed acknowledgment on pages one to six of the official specification document.

Post-service deliverables must include per-unit service reports, stamped schedules, maintenance officer sign-offs, temperature calibration reports, service certificates, and documented before-and-after temperature readings. Pricing must remain firm for ninety days, inclusive of VAT where applicable, and must cover all materials, labour, travel, and transport costs.

Skills Requirements

The successful bidder must demonstrate:

• Technicians holding current certification as qualified refrigerator mechanics.
• Proven experience and official authorization to service ultra-low temperature medical/freezer equipment.
• Competency in HVAC/R systems, electrical diagnostics, precision temperature calibration, and alarm system troubleshooting.
• Ability to deploy appropriately skilled personnel (artisans, apprentices, semi-skilled, and unskilled workers) as detailed in the labour scheduling framework.
• Strict adherence to occupational health and safety protocols, hospital infection control standards, and environmental compliance for refrigerant handling and disposal.

Explanation of Unusual or Complicated Terms

Minus 40 Fridge: Refers to ultra-low temperature freezers engineered to maintain environments at approximately -40°C. These units are essential in healthcare for preserving temperature-sensitive pharmaceuticals, vaccines, blood products, and biological specimens. Their complex dual-stage compression systems, stringent digital calibration demands, and strict environmental safety protocols require specialized technical expertise beyond standard commercial refrigeration.

80/20 Preference Point System: A South African preferential procurement framework where 80 points are allocated based on competitive pricing and 20 points are awarded for socio-economic transformation goals. This tender reserves full points for enterprises that are at least 51% black-owned.

SBD Forms: Standard Bidding Documents mandated by National Treasury. SBD 4 requires formal disclosure of any conflicts of interest or relationships with state employees, while SBD 6.1 is used to claim preference points for specific transformation goals. Failure to submit these correctly renders a bid non-responsive.
