Objectives

The primary objective is to construct a dedicated water storage stand and install a complete water supply system at Umzimkhulu Psychiatric Hospital. This maintenance project aims to ensure reliable water availability by erecting a secure structural foundation, installing a 10,000-litre storage tank, and integrating an inline booster pump to maintain consistent water pressure throughout the facility.

Scope of Work

The contract covers a full turnkey construction and installation project to be completed within six weeks from site handover, followed by a three-month guarantee period for all structural work and materials. The scope includes:

• Site Preparation & Earthworks: Vegetation clearance, trench and foundation excavation, backfilling, soil compaction, and chemical termite protection treatment.
• Structural Construction: Casting of reinforced and unreinforced concrete foundations and slabs, formwork installation and stripping, and brickwork wall construction to support the tank stand.
• Steel & Security Installation: Supply and assembly of a galvanized steel cage with expanded metal sheeting cladding, a lockable top lid, and heavy-duty padlocks.
• Plumbing Systems: Dismantling of existing toilet cisterns and pans, installation of the 10,000-litre vertical tank, copper piping networks, non-return valves, stop cocks, float valves, and integration with the main hospital water supply.
• Electrical & Mechanical Works: Routing of continuous armoured cabling, installation of circuit breakers and IP65 isolator switches, testing and commissioning, plus mounting and connecting an inline booster pump with its control panel.

Technical Requirements

All deliverables must comply with South African National Standards (SANS) and South African Bureau of Standards (SABS) regulations. Key technical mandates include:

• Material Specifications: Concrete must meet SANS 1200G; cement SANS 471/831; aggregates SANS 1083; reinforcement SANS 82; brickwork SANS 227; copper piping SANS 460; and galvanizing SABS 763. All electrical accessories require SABS approval.
• Health & Safety Protocols: A site-specific Health and Safety Plan with a detailed risk assessment is mandatory. Due to the psychiatric hospital environment, strict measures must prevent patient access to work zones, secure all materials against misuse, and minimize disruption to hospital operations.
• Testing & Quality Assurance: Independent testing authorities must validate concrete cube tests, mortar compressive strength, and electrical Certificate of Compliance (CoC). All supplied goods must be new, unused, and valid for a minimum of six months upon delivery.
• Regulatory Compliance: Full adherence to the Occupational Health and Safety Act, proper waste disposal, and compliance with municipal and provincial building codes are compulsory.

Skills & Qualification Requirements

Bidders must prove technical competence, financial readiness, and regulatory standing through the following criteria:

• CIDB Registration: Valid registration under General Building Work with a minimum grading of 1 GB.
• Financial Capability: Official proof of available capital or a bank credit limit letter covering at least 50% of the quoted contract value.
• Trade Certifications: Legal and current certificates for qualified electricians and plumbers. These qualifications must belong to a shareholder, director, or the designated executing artisan.
• Proven Experience: Submission of at least one verifiable past project reference and completion certificate demonstrating similar construction or mechanical installation experience.
• Evaluation Threshold: A minimum score of 70 out of 100 points is required across financial capability, trade qualifications, and past experience.
• Post-Award Compliance: Successful contractors must submit a site-specific H&S file, comply with Expanded Public Works Programme (EPWP) labour targets, provide a detailed execution schedule, and ensure all personnel wear identifiable workwear.
