Objectives

The primary objective is to procure, deliver, install, test, and commission new commercial-grade air conditioning units at the Church of Scotland Hospital. The project aims to restore and maintain optimal climate control in designated clinical and administrative areas while ensuring zero disruption to active healthcare services.

Scope of Work

• Supply, deliver, and install two 60,000 BTU units in the Male Medical Ward and one 36,000 BTU unit in the Audiology department.
• Safe removal and environmentally compliant disposal of existing air conditioning equipment.
• Complete installation of indoor and outdoor units, including supply of mounting brackets, accessories, and structural supports.
• Execution of all refrigeration piping, insulation, condensate drainage, and containment systems.
• Electrical integration into a dedicated three-phase distribution board, including pressure testing, vacuum evacuation, system commissioning, and formal handover.
• Necessary builders' work, including core drilling, structural patching, and painting touch-ups to restore premises to original condition.

Technical Requirements

• Unit Type: Three-phase (380V) under-ceiling commercial models.
• Cooling Capacity: 36,000 BTU and 60,000 BTU units.
• Heating Capacity: 15kW heat pump functionality.
• Refrigerant: R32 preferred; R410A acceptable if R32 is unavailable.
• Indoor Unit Specifications: Dimensions 1600mm × 650mm depth, operating noise below 45dB, mounted via M8 threaded rods.
• Outdoor Unit Specifications: Twin rotary inverter compressor with anti-corrosive coil.
• Piping: Insulated copper flare connections (liquid 3/8" plus gas 5/8" or ¾").
• Controls: Wall-mounted or wireless remote controllers with 24-hour timer and dry contact interface.
• Compliance: All equipment must be brand new, unused, carry a minimum six-month validity post-delivery, and comply with SANS/SABS standards, National Building Regulations, and Occupational Health and Safety Act requirements.

Skills and Qualification Requirements

• Statutory Registration: Valid CIDB Grading Category 1ME certification, authorizing execution of minor electrical and HVAC works up to R2 million.
• Proven Experience: Submission of a completed purchase order and certificate of satisfactory performance for a similar HVAC installation in a public or private healthcare facility.
• Corporate Documentation: Updated CIPC registration documents, valid B-BBEE verification certificate or sworn affidavit, and proof of tax clearance/Central Supplier Database (CSD) registration.
• Technical Personnel: Deployment of certified refrigeration technicians, licensed electricians, and skilled installers capable of performing precision pipework, electrical tie-ins, and ceiling mounting in sensitive environments.

Notable Terms and Services

CIDB 1ME Grading: A South African Construction Industry Development Board classification for minor electrical and mechanical projects. It ensures contractors meet national competency, financial, and technical thresholds for safe HVAC and electrical installations.

Three-Phase Commercial HVAC: Unlike residential systems, these units require balanced three-phase power distribution, specialized load calculations, and industrial-grade mounting hardware to handle continuous clinical loads.

Refrigerant Handling (R32/R410A): R32 is mildly flammable and requires certified handling and leak-detection protocols. R410A operates at significantly higher pressures, mandating precise evacuation and pressure-testing procedures to prevent system failure.

Occupied Healthcare Environment: All work must adhere to strict infection prevention, noise limitation, and safety protocols. Contractors must schedule disruptive activities strategically to avoid interfering with patient care and hospital operations.

Delay Penalty Clause: A contractual penalty of 0.4% per calendar day applies for late completion or failure to meet agreed milestones, deducted directly from the contract value.

Preferential Procurement System: Evaluation follows an 80/20 point allocation model (80 points for competitive pricing, 20 points for socio-economic goals specifically favoring enterprises registered within the uMsinga Municipality).
