Objectives

The primary objective is to repair and restore two hot water storage tanks in the nursery section to full operational capacity while ensuring strict compliance with health, safety, and quality standards mandated by the provincial health department.

Scope of Work

• Bypass the second tank to isolate and perform repairs on the first tank only.
• Drain all water using a submersible pump if a drain valve is unavailable.
• Carefully dismantle the tank to record its configuration, then reconstruct it to match the original design.
• Replace corner framing with specified stainless steel angle iron and fabricate a welded frame without bolt-and-nut joints.
• Install new insulation panels, reposition checker plates, and reuse existing tank lids.
• Fabricate and install internal piping assemblies and heat exchange coils matching existing dimensions.
• Repair all identified leaks, replace valves, and commission the tank back into service.
• Expected project duration: one calendar month (20 working days).

Technical Requirements

• Materials: Must include 316 stainless steel angle iron (100mm × 10mm), 80mm thick freezer panels, 316 stainless steel ball valves with Teflon seals, and custom-manufactured 316 stainless steel heat exchange coils.
• Welding Standards: Frame joints must be fully welded with smooth finishes; mechanical fasteners are prohibited for structural assembly.
• Guarantees: New components carry a 12-month guarantee, repairs carry a 6-month guarantee, and overall workmanship/materials carry a 2-year warranty.
• Documentation: Submission of a completed three-page Bill of Quantity, signed tender forms, trade test certificates for the lead welder/boilermaker, and proof of IME, ISO, or CIDB registration.
• Safety Compliance: A comprehensive safety file must be submitted prior to mobilization, including risk assessments, organograms, legal safety appointments, PPE registers, valid medical surveillance certificates, and site-specific cordoning protocols.
• Invoicing Model: Payments operate on a cost-proven basis, requiring daily job cards, supplier invoices, and formal credit notes for any unused quoted funds.

Skills Requirements

• Lead Technician: A coded welder or boilermaker with a valid trade test certificate must oversee execution.
• Personnel Credentials: All workers must hold documented competency accreditation, valid fitness certificates, and appropriate identification or work permits.
• Project Management: A designated company project leader must coordinate daily operations, attend safety inductions, and maintain daily job cards and work plans.
• Electrical Exclusion: Contractors are strictly prohibited from touching electrical components; all electrical removal/replacement must be coordinated separately with the hospital’s electrical foreman.
• Labor Mix: Appropriate deployment of skilled artisans, apprentices, semi-skilled, and unskilled labor as outlined in the tariff schedule.

Notable Terms and Conditions

Canfis: Local industry terminology referring to internal distribution baffles or piping assemblies within the hot water tank that require precise custom fabrication and secure flange connections.

Sprague Coils: Specialized copper or stainless steel heat exchange tubes used to transfer thermal energy within the storage tank; must be manufactured to exact diameter and coil pitch specifications.

Cost-Proven Basis: A reimbursement model where payment is tied to verified actual expenditures rather than a fixed lump sum, necessitating rigorous daily documentation and supplier invoice verification.

Preference Points System: An 80/20 evaluation framework allocating 20 points exclusively to enterprises registered and operating within the eThekweni district.

Compulsory Site Briefing: Attendance at a mandatory on-site meeting is a strict pre-qualification requirement; failure to attend results in immediate disqualification.
