Tender Summary: BID 22.2026 Debris Removal

Objectives

The primary objective is to restore and maintain the hydrological function and ecological integrity of the Breëde River course by systematically removing accumulated debris, sediment, and invasive vegetation across multiple farm properties in the Cape Winelands region.

Scope

The project encompasses works distributed across various farm locations within the specified river course and is structured into two distinct work packages:

• Part A – Mechanised Earth Moving: Extraction and relocation of large volumes of sand, rock, and general debris from the riverbed and adjacent areas.
• Part B – Specialised Alien Clearing: Targeted removal of non-native invasive plant species that obstruct water flow and degrade local biodiversity.

All activities must align with mandatory site inspections and adhere to strict submission deadlines.

Technical Requirements

• Deployment of heavy machinery capable of safely operating in riverine environments while managing high-volume sediment and rock extraction.
• Implementation of environmentally sensitive clearing methodologies to prevent soil erosion, protect native flora, and minimise downstream sediment runoff.
• Mandatory attendance at two compulsory site meetings scheduled for 16 November 2026 at designated project locations.
• Strict compliance with all documentation, terms and conditions, supply chain management policies, and annual declaration forms referenced in the full tender package.
• Bid submission must occur strictly by 12:00 PM on 3 December 2026.

Skills Requirements

While explicit qualifications are not detailed in the available information, successful execution requires demonstrated expertise in:

• Heavy equipment operation, site logistics, and safety management in sensitive aquatic and riparian zones.
• Ecological restoration and invasive species control, including botanical identification, sustainable clearing techniques, and post-clearance monitoring.
• Project coordination, environmental compliance, and adherence to municipal or provincial land rehabilitation standards.

Contractors should provide evidence of prior experience in similar river rehabilitation, debris clearance, or land remediation projects.

Clarification of Specialised Terms

Specialised Alien Clearing: Refers to the controlled eradication of invasive plant species that outcompete indigenous vegetation, disrupt natural water flow, and increase fire risk. This process typically requires precise botanical identification, mechanical or approved chemical treatment, and follow-up monitoring to ensure long-term ecological recovery without damaging surrounding habitats.

Mechanised Earth Moving: Denotes the use of excavators, loaders, and haulage vehicles to reposition substantial quantities of riverbed material. In sensitive aquatic environments, this requires careful planning and engineered controls to minimise bank destabilisation, prevent excessive turbidity, and comply with environmental protection standards.
