Objectives

The primary objective of this Request for Quotation (RFQ) is to procure professional roofing maintenance and repair services for Traffic Services facilities under the Buffalo City Metropolitan Municipality. The project aims to restore roof integrity through specialized rubberizing treatments, mitigate asbestos-related health hazards, execute minor structural repairs, and ensure long-term weatherproofing while complying with municipal procurement and occupational health standards.

Scope of Work

The successful bidder will execute the following deliverables:

• Remove loose rusted screws and replace them with cap-on roof screws.
• Gently clean asbestos roofs to treat moss and lichen using an antifungal biocide wash, strictly avoiding high-pressure methods to prevent toxic dust release.
• Clean gutters of all debris and arrange for off-site removal.
• Implement safe containment and disposal procedures for hazardous asbestos residue.
• Seal gable walls and asbestos surfaces with a specified sealant prior to rubberizing.
• Apply one coat of SABS-approved bonding primer/sealer to roof surfaces.
• Seal roof ridges with bitumen before coating.
• Apply two coats of SABS-approved rubberizing paint to asbestos roofs.
• Repair damaged gutters using matching heavy-duty galvanized zinc.
• Internally rubberize all gutters with two coats and externally paint them with SABS-approved terracotta PVA paint (two coats).
• Manage a R50,000 contingency allowance and provide a Certificate of Completion (C.O.C.) upon finishing all works.
• Leave the site neat and tidy, remove all debris, and submit a comprehensive safety plan before mobilization.

Technical Requirements

Bidders must demonstrate technical capability to execute the scope while adhering to strict material and procedural standards:

• All paints, primers, and sealants must hold valid SABS approval for use on asbestos and rubberized roofing systems.
• Strict adherence to Occupational Health and Safety (OHS) regulations regarding asbestos handling, including controlled cleaning pressures and certified waste disposal pathways.
• Submission of a detailed site-specific safety plan prior to commencement of works.
• Provision of a formal Certificate of Completion (C.O.C.) verifying that all works meet municipal quality standards.
• Compliance with a 10% retention payment clause, where funds are withheld until the first heavy rain event confirms the roof’s watertight integrity.
• Pricing must be fixed for the contract duration, inclusive of VAT where applicable, and submitted electronically via the municipality’s designated vendor portal.

Skills & Experience Requirements

To qualify for evaluation, bidders must meet the following mandatory criteria:

• Maintain a Broad-Based Black Economic Empowerment (B-BBEE) status of Level GB1 or higher.
• Demonstrate proven experience in roof rubberizing or comparable roofing restoration projects, supported by official works orders or reference letters accompanied by completion certificates.
• Hold active registration on the Central Supplier Database (CSD) and the Buffalo City Metropolitan Municipality Supplier Database.
• Ensure all tax matters are in order and verified through government databases.
• Provide a duly authorized signatory letter and complete all statutory municipal bidding declarations, including conflict of interest and past supply chain management practice disclosures.
• Capable of managing hazardous material handling, site safety compliance, and warranty/retention verification processes.

Notes on Unusual or Complicated Terms

Asbestos Handling Protocols: The scope involves working on asbestos roofs, which requires specialized low-pressure cleaning techniques to prevent airborne toxic fibers. Bidders must implement engineered controls and certified disposal methods to comply with national OHS legislation.

Retention Clause: A 10% payment retention is applied, released only after the first significant rainfall. This ensures the contractor guarantees waterproofing performance before final settlement.

SABS Approval: All chemical coatings and construction materials must carry South African Bureau of Standards certification, ensuring they meet national durability and safety benchmarks for roofing applications.

80/20 Preference Scoring: Evaluation uses a standard municipal procurement model allocating 80 points to price competitiveness and 20 points to specific socio-economic goals (B-BBEE level and geographic locality within the Eastern Cape).
