Objectives

The primary objective is to appoint a qualified service provider to replace an existing thatch roof with Harvey tiles at designated areas within the National Zoological Garden in Pretoria. The project aims to deliver a durable, compliant roofing solution while ensuring strict adherence to health, safety, and environmental standards.

Scope of Work

The successful bidder will execute the complete removal of approximately 600 square metres of existing thatch roofing, install new Harvey tiles (concrete interlocking roof tiles engineered for high durability and weather resistance) supported by 38x38mm purlins, and arrange off-site disposal of all demolition waste. The scope encompasses the supply of all labour, materials, machinery, transport, and supervision. Additional responsibilities include conducting pre-commissioning checks, full system testing, submitting commissioning reports, and providing a twelve-month guarantee on all installed components. All activities must comply with municipal regulations, SANS building codes, and the Occupational Health and Safety Act.

Technical Requirements

• CIDB Grading: Bidders must hold a Construction Industry Development Board contractor grading designation of Level 1 GB or higher, which certifies baseline competency in civil construction works.
• Re-measurement Contract: Final payments will be calculated based on actual quantities executed rather than initial estimates, requiring accurate tracking of installed materials.
• Financial Security: A performance guarantee equal to 10% of the approved contract sum is mandatory. Public liability insurance must cover a minimum of R5,000,000 per claim.
• Payment & Retention: Progress payments will be processed within 30 days. A retention amount of 10% will be withheld from invoices, capped at 5% of the contract value, reducing to 2.5% upon practical completion.
• Regulatory Compliance: Valid proof of Central Supplier Database registration, Compensation for Occupational Injuries and Diseases Act (COIDA) good standing (covering workplace injury compensation), tax clearance status, and Broad-Based Black Economic Empowerment (B-BBEE) verification are compulsory.
• Defects Liability: A twelve-month period applies post-completion for rectifying any latent defects at no additional cost.

Skills and Experience Requirements

• Project Experience: Demonstrated track record in similar roofing or construction projects completed within the last ten years, supported by appointment letters, completion certificates, and verifiable client references.
• Technical Personnel: Appointment of a dedicated full-time site technician or agent holding a recognised built environment qualification (e.g., Civil Engineering Technician) with one to four years of relevant field experience.
• Methodology: Submission of a detailed, location-specific project plan outlining execution strategies, resource allocation, quality control measures, and risk mitigation.
• Evaluation Framework: Tenders are evaluated using an 80/20 preference point system. Eighty percent of scoring is based on competitive pricing, while twenty percent is allocated to preferential procurement goals targeting historically disadvantaged groups based on verified black and female ownership percentages.

Key Terms and Conditions

The contract imposes strict operational and financial conditions. Contractors bear full risk for damage or destruction of works during construction and must implement a comprehensive Health and Safety Plan aligned with national construction regulations. Delay penalties are fixed at R400 per day. Price adjustments for material cost fluctuations are not permitted, requiring bidders to factor potential inflation into their initial rates. Any disputes arising from the agreement will be resolved through binding arbitration rather than litigation.
