Tender Summary: Construction of Murangoni Bridge (Low Level Bridge)

Objectives

The primary objective of this tender is to appoint a qualified contractor for the construction of the Murangoni Bridge, specifically a low-level bridge. The project aims to provide a safe and reliable river crossing, likely for rural access, improving connectivity and resilience against seasonal flooding. The bridge must be delivered to the specifications of Thulamela Local Municipality, ensuring structural integrity and compliance with local engineering standards.

Scope of Work

The scope encompasses the full construction of a low-level bridge at the Murangoni site. This includes all civil engineering works necessary for a bridge of this type, such as substructure (foundations, piers/abutments), superstructure (deck, beams), approach roads, drainage, and any associated earthworks. The contractor is expected to manage all aspects of site establishment, materials supply, labour, plant, and quality control. The project is to be completed within the timeframe specified in the tender documents, with a compulsory site meeting to clarify expectations.

Technical Requirements

• Low-Level Bridge Design: A low-level bridge is designed to be overtopped during high water flows. This means the deck is set at a low elevation relative to the riverbank, allowing water to flow over the bridge during floods. The design must incorporate scour protection, debris resistance, and appropriate drainage to prevent structural damage during submersion.
• Construction Standards: All works must comply with the South African standard specifications for civil engineering (e.g., SANS 1200 series or equivalent) and the municipality's specific requirements. The bridge must be built to withstand hydraulic loads, vehicle loads, and environmental conditions.
• Compulsory Clarification Meeting: A mandatory site meeting is scheduled at the Murangoni Bridge location. Attendance is compulsory for all tenderers to understand site conditions, access constraints, and any local issues. Failure to attend will result in disqualification.
• Tender Documentation: Tenders must be submitted on the official documentation provided. A non-refundable deposit (R1,148.00 cash) is required to obtain the documents, and there is an additional charge of R4 per page for any extra copies. This ensures only serious bidders participate.
• Sealing and Delivery: Tenders must be sealed, addressed, and delivered as per the Tender Data. Late submissions will not be accepted under any circumstances.

Skills and Qualification Requirements

• cidb Contractor Grading: Tenderers must hold a valid contractor grading designation of 5CE or higher from the Construction Industry Development Board (cidb). This grading indicates the contractor has the financial, technical, and experience capacity to undertake civil engineering works of a certain magnitude. A 5CE grading typically allows for projects valued between R6.5 million and R13 million, reflecting the expected scale of this bridge.
• Experience: The contractor must demonstrate prior experience in similar bridge or heavy civil construction projects, particularly involving river crossings or hydraulic structures. This is implied by the cidb grading but may be further assessed through references.
• Compliance: The successful tenderer must comply with all relevant South African legislation, including the Occupational Health and Safety Act, and must have the necessary insurance and registration with the Compensation Fund.
• Preference: Preference points will be awarded to tenderers who meet the 5CE or higher grading, as per the municipality's procurement policy. This is not a separate requirement but a scoring criterion.

Additional Notes

The tender process is strictly governed by the municipality's supply chain management regulations. The compulsory meeting ensures all bidders have equal knowledge of the site. The non-refundable deposit covers administrative costs and discourages frivolous bids. The project is expected to be funded through municipal capital budgets, and the contractor must be prepared for potential phased payments based on progress milestones. The low-level bridge design is a cost-effective solution for areas with seasonal flooding, but it requires specialised engineering knowledge to ensure safety and durability.
