Objectives

The primary objective of this tender is to deliver the second phase of the Inchanga Sewer Rising Main upgrade project. The initiative aims to expand wastewater conveyance capacity, improve system reliability, reduce overflow risks, and ensure long-term compliance with Johannesburg Water’s infrastructure development and service delivery targets.

Scope

The project encompasses civil and mechanical engineering works for Package 2 of the sewer rising main upgrade. This includes excavation, pipeline installation or rehabilitation, pump station interface works, hydraulic testing, commissioning, and site restoration. All activities must strictly follow the technical specifications, drawings, bill of quantities, and contractual conditions provided in the official tender documentation issued by Johannesburg Water.

Technical Requirements

• Mandatory Pre-Qualification: Only contractors holding a CIDB grading of 8CE or higher are eligible to submit tenders.
• Documentation Compliance: Tenders must be completed using only the official forms and templates supplied by the employer; omissions or unauthorized modifications will result in disqualification.
• Quality & Safety Standards: All works must comply with South African National Standards (SANS), municipal bylaws, occupational health and safety legislation, and environmental management protocols for water infrastructure projects.
• Project Delivery Constraints: Submissions must adhere to specified sealing, addressing, and delivery procedures, with late or electronically submitted tenders explicitly rejected.

Skills Requirements

Although the tender notice does not list individual personnel qualifications, the mandatory CIDB 8CE grading inherently requires bidders to demonstrate comprehensive technical and managerial capacity. Contractors must employ qualified project managers, civil and water engineers, certified site supervisors, and skilled tradespeople proficient in heavy civil construction, pressurized pipeline joining/welding, pump and valve installation, hydraulic testing, and trenchless rehabilitation techniques. Firms must also maintain sufficient financial liquidity, equipment fleets, and risk management systems to execute large-scale municipal infrastructure projects safely and on schedule.
