Tender Summary: Supply, Deliver, Installation & Commission Macerator Machine

Objectives

The primary objective is to procure, supply, deliver, install, and commission a commercial food waste macerator system for the kitchen department at Umgeni Hospital. The project aims to replace an outdated unit with a high-capacity, hygienic, and durable solution that complies with institutional health and safety standards while ensuring efficient organic waste management.

Scope of Work

• Supply of one (1) commercial food waste macerator unit meeting detailed technical specifications.
• Custom fabrication and installation of a stainless steel workstation, including backsplash, cleaning table, and integrated foreign object screening strainer.
• Integration of the new system with existing plumbing and drainage infrastructure within a confined workspace.
• Safe removal and transportation of the existing macerator unit to the designated workshop.
• Full installation, testing, and commissioning of the equipment.
• Provision of a comprehensive warranty and a structured long-term maintenance service plan.

Technical Requirements

• Machine Specifications: 5 HP capacity, 3-phase power supply, dual voltage operation, fan-cooled motor with ball bearings and integral overload protection. Dynamically balanced for smooth operation.
• Grinding Mechanism: Cast iron grind and exit chambers, 10-inch heavy-duty cast stainless steel turntable, three jam-resistant hardened stainless steel swivel impellers with tungsten carbide inserts, six ripper bars, and a hard cast alloy grind ring with dual-stage action.
• Construction & Materials: All fabricated components must be food-grade stainless steel (minimum 304/404 grade), corrosion-resistant, and designed for high-volume institutional use. Edges must be smooth and hygienic.
• Safety & Integration: Under-counter unit placement for stability and maintenance access. Heavy-duty removable stainless steel inlet screen to prevent cutlery, bones, and metal objects from entering the grinding chamber. Must accommodate existing shower rose water supply and drainage lines.
• Warranty: Minimum twelve (12) months comprehensive coverage covering parts, labour, call-outs, travel, and repair costs.
• Maintenance Plan: Twenty-four (24) months of scheduled service, including biannual preventative visits, electrical/component inspections, wear-part replacement, safety verification, and documented breakdown response.

Skills & Experience Requirements

• Proven experience in supplying and installing commercial food waste disposal systems in healthcare or large-scale institutional settings.
• Certified or demonstrated competency in mechanical and electrical installation of 3-phase industrial equipment.
• Skilled in custom stainless steel fabrication and spatial integration within confined or legacy kitchen layouts.
• Capability to safely dismantle, remove, and transport heavy existing machinery.
• In-house or contracted technical team capable of executing long-term preventative and corrective maintenance protocols.
• Familiarity with South African public sector procurement compliance, including CSD registration, tax clearance validation, and SBD documentation.

Notes on Unusual or Complicated Terms

• Macerator Machine / Food Waste Disposer: An industrial grinding unit that pulverizes organic kitchen waste into a fine slurry, allowing it to pass safely through standard drainage pipes. It significantly reduces solid waste volume and improves kitchen sanitation.
• Custom Stainless Steel Fabrication: Bespoke countertop and screening station engineering required to adapt the macerator to the hospital’s existing confined space and plumbing configuration while maintaining strict hygiene and splash-containment standards.
• 80/20 Preference Point System: A South African public procurement evaluation model where 80 points are awarded based on competitive pricing and 20 points are allocated for socio-economic goals, specifically full ownership by Black Africans.
• SBD Forms & CSD Registration: Mandatory South African government bidding compliance tools. SBD (Standard Bidding Document) forms declare legal, tax, and conflict-of-interest status, while CSD (Central Suppliers Database) registration verifies supplier legitimacy and tax compliance.
