Tender Summary: Hire of Excavator for the Dredging of 5 Tidal Pools

Objectives

The primary objective is to engage a qualified service provider to hire and operate an excavator for the dredging and sand removal from five designated tidal pools within the Umdoni Municipality jurisdiction. The municipality seeks to restore pool hydrology, enhance recreational safety, and preserve coastal ecosystems through controlled mechanical excavation.

Scope of Work

The successful bidder will supply one excavator and execute sand extraction across five specific locations: Umthwalume, Ifafa, Pennington, Preston, and Park Rynie. The contractor must remove sand down to the underlying concrete base of each pool. Extracted sand must be relocated 10 to 20 metres away from each pool, positioned on the left-hand side when facing seawards, and mechanically flattened to prevent stockpiling. The service provider assumes full responsibility for site safety, security, immediate waste disposal, and post-completion rehabilitation of all disturbed areas. Works must be executed within mutually agreed commencement and completion dates.

Technical Requirements

• Provision of one suitable, well-maintained excavator operated by competent personnel.
• Execution of dredging exclusively during low spring tide windows to ensure safe access and effective sediment removal.
• Precise excavation depth control until the concrete foundation is exposed.
• Strict adherence to mandated sand placement protocols regarding distance, orientation, and flattening.
• Implementation of protective measures to prevent damage to existing coastal infrastructure and sensitive sand dune vegetation.
• Full rehabilitation of affected zones upon project completion at the contractor's sole expense.
• Compliance with the General Conditions of Contract (GCC), including performance security, insurance, delay penalties, and termination clauses.
• Submission of mandatory returnable documents, including tax compliance PINs, Central Supplier Database (CSD) registration proof, BBBEE documentation, and a signed quotation valid for 30 days.

Skills and Experience Requirements

• Proven track record in coastal maintenance, dredging, or heavy machinery operations within environmentally sensitive zones.
• Demonstrated capability to plan and execute tidal-dependent construction activities safely and efficiently.
• Strong project management competencies to coordinate machinery deployment, specify realistic timelines, and manage site rehabilitation.
• Working knowledge of occupational health and safety standards, particularly concerning coastal works and heavy equipment operation near public infrastructure.
• Administrative proficiency to compile mandatory bidding documents, comply with preferential procurement scoring frameworks, and adhere to public sector supply chain management regulations.

Unusual or Complicated Terms and Services

• Low Spring Tide Operations: Dredging must be scheduled to coincide with exceptionally low tidal levels. This requires precise meteorological and oceanographic planning, as contractors must possess expertise in timing marine-adjacent works to avoid weather disruptions and ensure safe machinery access.
• SABS Material Requirement: Any supplementary materials used for site rehabilitation or structural repairs must carry South African Bureau of Standards certification, guaranteeing compliance with national quality, durability, and safety benchmarks.
• Preferential Procurement Scoring (80/20 or 90/10 System): A standard South African public procurement evaluation framework where bids are scored primarily on price (80 or 90 points) with the remainder allocated for socio-economic goals such as black ownership percentages and local enterprise location. Points must be substantiated with sworn affidavits or official verification certificates.
• General Conditions of Contract (GCC): Comprehensive national treasury guidelines governing public sector contracts. These detail binding obligations including payment terms, interest-based delay penalties, termination rights, dispute resolution pathways, anti-collusion mandates, and liability limitations. Bidders must thoroughly review these clauses prior to submission.
