Tender Summary: Servicing of Water Storage Tanks

Objectives

To procure a qualified contractor for the thorough cleaning, maintenance, and repair of existing water storage infrastructure at the Church of Scotland Hospital and affiliated Primary Health Care (PHC) facilities. The objective is to restore hygienic water storage capacity, ensure regulatory compliance, and maintain uninterrupted healthcare operations.

Scope of Work

The contract encompasses the servicing of six distinct tank categories across institutional and PHC sites:

• Concrete Main Tank (1 ML): Seal leaks, extract bottom sludge, verify gate/ball valve functionality, and repair the level gauge.
• Concrete Secondary Tank (300 kL): Remove sludge, seal perimeter leaks, ensure secure lid closure, service the ball valve, and install a new system gauge.
• Plastic Tanks (10 kL × 17 units): Full internal/external cleaning, sludge removal, replacement of missing lids, and ball valve servicing across hospital and clinic locations.
• Plastic Tank (5 kL × 1 unit): Internal/external cleaning, sludge removal, and lid replacement.
• Steel Ground-Place Tank (60 kL): Extract and dispose of mud/sludge off-site, seal panel leaks, inspect and replace inlet valve handles.
• PHC Galvanized Elevated Tank (5 kL): Sludge extraction and off-site disposal, panel leak sealing, valve handle inspection/replacement, site cleanup, commissioning, and submission of a comprehensive service report with invoice.

The contract duration is strictly one week from site handover, followed by a minimum twelve-week guarantee period. A daily penalty of 0.4% applies for delayed completion.

Technical Requirements

• Full compliance with SABS codes of practice, National Building Regulations, KZNPA Standard Preambles, KZNPA General Specifications, and the Occupational Health and Safety Act.
• All extracted sludge and mud must be transported and disposed of outside the facility premises.
• Complete cleaning of all adjacent work areas is mandatory upon completion.
• Work execution must prioritize minimal disruption, as the hospital remains fully operational throughout the contract.
• Submission of a detailed technical report covering services rendered, maintenance recommendations, and a formal invoice.
• Bidders must conduct a pre-tender site inspection to assess access, logistics, and existing conditions; failure to account for site realities will not excuse performance deficiencies.
• Mandatory returnable documents include a valid CIDB Grade S01 certificate, proof of prior similar water tank servicing experience (signed/stamped by a previous client), updated CIPC registration, B-BBEE verification/affidavit, and SARS tax compliance clearance.

Skills and Competency Requirements

• Proven practical experience in industrial water tank desludging, leak sealing, and structural maintenance.
• Technical competence in servicing plumbing and mechanical components, including ball valves, gate valves, inlet handles, and liquid level gauges.
• Knowledge of safe biological waste handling and compliant off-site disposal protocols.
• Project management capability to execute multi-tank maintenance within a strict one-week window while adhering to health and safety standards.
• Proficiency in generating detailed commissioning reports, technical recommendations, and public-sector-aligned financial documentation.
• Familiarity with South African public procurement compliance frameworks and supply chain management protocols.
