Tender Summary: Supply and Install Air Conditioners to Jack Metz 3rd Floor, Braamfontein

Objectives

The primary objective is to procure, deliver, and professionally install a specified quantity of commercial air conditioning units within the third floor of the Jack Metz building, operated by the National Health Laboratory Service (NHLS). The project aims to enhance climate control in a sensitive healthcare environment while ensuring full compliance with public procurement regulations, safety standards, and operational continuity requirements.

Scope of Work

• Equipment Supply: Provision of 15 twin duct console-type inverter air conditioners (Unicorn-MP 40, DC), one 12,000 BTU midwall split unit, and two 36,000 BTU midwall split units. All units must support both heating and cooling functions.
• Installation & Integration: Complete installation including ducting, foam sealing for wall penetrations, drilling, and subsequent plastering/painting restoration. Piping and cabling must be routed through PVC trunking/ducting.
• Electrical Works: Installation of eighteen 30-amp single-phase isolators wired from the distribution board, complete with 25-amp circuit breakers, trunking, bends, and end caps.
• Operational Constraints: Work must be executed in phased stages, potentially during evenings or weekends, to avoid disrupting active laboratory operations, sensitive electronic equipment, and nearby operating theatres. Coordination with hospital management is mandatory.
• Documentation & Handover: Provision of a Certificate of Compliance (COC) upon completion, along with a 12-month guarantee/maintenance period and a 5% retention hold for three months post-acceptance.

Technical Requirements

• Unit Specifications: All air conditioners must be inverter-type, utilizing R32 or R410A refrigerants. Approved manufacturers include Maclaren, Carrier, Daikin, Samsung, LG, or York.
• Compliance Standards: All materials and installations must be SABS approved and adhere to SANS 10142 electrical installation rules. (Note: SANS 10142 is the South African national standard governing low-voltage electrical installations in buildings.)
• Wiring & Isolation: Each unit requires separate wiring from the distribution board via a dedicated isolator and circuit breaker. A double-pole (D/P) isolator must be installed internally adjacent to each unit.
• Site Management: A qualified project supervisor must remain on-site throughout the execution to maintain NHLS standards. Contractors must account for vibration restrictions near sensitive lab equipment and theatre areas.
• Contractual Terms: Quotations must be all-inclusive (excluding VAT), fixed in ZAR, and valid for 90 days. Delay penalties apply at 1% of the total contract value per day. The evaluation follows an 80/20 preference point system. (Note: This system allocates 80 points based on price competitiveness and 20 points based on socio-economic development goals, such as B-BBEE status and enterprise size.)

Skills and Qualification Requirements

• Licenses & Certifications: Submission of valid Air Conditioning Trade Test Certificate, Electrical Wireman’s License, and Plumbing Trade Test Certificate (if applicable). CIDB registration confirmation with a minimum Grading Level 2 ME is mandatory. (Note: CIDB refers to the Construction Industry Development Board; Level 2 ME indicates a contractor capable of executing medium-complexity mechanical engineering projects up to a specific financial threshold.)
• Personnel: A detailed CV and certification for the appointed Project Manager must be provided. Only registered electricians and plumbers may perform respective trades.
• Experience & References: Bidders must submit signed completion certificates or reference letters for similar projects completed within the last five years, scaled according to the contract value brackets outlined in the tender.
• Regulatory Compliance: Valid Tax Clearance PIN or SARS Tax Compliance Status certificate, Central Supplier Database (CSD) registration, and a sworn affidavit or verified BBBEE certificate to claim preference points under the Specific Goals framework.
• Attendance: Mandatory participation in the compulsory site meeting to assess working conditions and logistical constraints before submission.
