AP2362: RFQ: RE-ADVERTISEMENT: CK & GR ELECTRICITY PROJECT 2023: BOTRIVIER: RESTORATION AND REHABILITATION: PROFESSIONAL CIVIL ENGINEER – SPECIALISING IN HYDROLOGICAL AND HYDRAULIC ENGINEERING 

The September 2023 flood caused the river to flow wider resulted the riverbanks to erode in which caused soil erosion and damage to farms during the flood. 

OBJECTIVES

1. To produce a temporary short-term solution
2. To reduce sediment loss for the catchment
3. Reduce erosion of the riverbanks in the catchment.
4. To alleviate sedimentation problems at the N2 bridge. 

GENERAL REQUIREMENTS

The works is to provide advice and plans to the farming community on what to do with the sediment and other obstacles that was displaced during the 2023 flood events and how to do rehabilitation on the riverbanks. The river systems will also need to be analyzed to provide solutions.

Botriver is approximately 27km to the bridge (34.219175°S 19.208596°E). The engineer will probably need to go past the bridges Location of this project:

• Conduct a hydrological study is an investigation and analysis of the distribution, movement, and properties of water and involves examining various aspects of water resources, such as changes to rainfall patterns, runoff and streamflow influenced by global warming (or at least considers the consequences of changing weather patterns).
• Communicate and arrange entrance with affected farmers and local WCDOA.
• Evaluate the findings and proactive steps to the WCDoA and farmers.
• Determine any possible high-risk areas.
• A river survey (using an RTK GPS or instrument to give similar accuracy in elevation data) should be done, with a proper catchment analysis and possible solutions to prevent further damaged and or sedimentation. Plans to remove sediment and to place the stream as close as possible to its original position before the flooding.
• Write a design report, with possible/practical solutions, including a costing for the implementation of this rehabilitation solution.
• Supply aerial photos of the river system.
• The sediment blockage under the bridge at the N2 should also be evaluated

The quoted amount will be a lump sum bid and must include labor and machinery to conduct the above studies.

The successful bidder must have the capacity to start the works within 7 (seven) days of appointment and complete the work within 60 (Sixty) calendar days.

In accordance with Casidra’s Preferential Procurement Policy, this bid is subject to a functionality compliance test. B-BBEE certified bids will receive preferential scores.
