RFQ Summary: Galvanised Flange Welding

Objectives

The primary objective of this Request for Quotation (RFQ) is to procure a qualified service provider to perform specialised welding services for the City of uMhlathuze. Specifically, the work involves the welding of flanged pipes with 20mm spool pieces to connect level dex control valves at various reservoirs. The project also includes the activation of Bermad valves at the Primary reservoir and Reservoir 12.

Scope of Services

The scope of work is defined as follows:

• Welding Services: Welding of flanged pipes with 20mm spool pieces to connect level dex control valves.
• Locations: Work is to be performed at Reservoirs 1, 2, 3, 4, 5, and 13.
• Valve Activation: Activation of Bermad valves at the Primary reservoir and Reservoir 12.
• Site Meeting: A compulsory site meeting is scheduled for 25 August 2026 at 09h00 at the Plumbers Depot, A 1227, Sundu Road. Attendance is mandatory.
• Closing Date: Quotations must be submitted by 28 August 2026 at 12h00.

Technical Requirements

Bidders must meet the following technical and compliance requirements:

• CIDB Grading: The bidder must have a valid Construction Industry Development Board (CIDB) grading of 1CE/PE or higher. This grading is for civil engineering (CE) and general building (PE) works.
• Central Supplier Database (CSD): The supplier must be registered on the Central Supplier Database (CSD). The CSD number must be provided. Suppliers not registered will not be considered.
• Letter of Good Standing: A valid Letter of Good Standing from the Compensation Fund (for the Principal Contractor and any Sub-Contractors) must be provided.

Skills and Experience Requirements

The required skills and experience are implied by the technical specifications:

• Welding Expertise: Proven experience and capability in specialised pipe welding, specifically galvanised flanged pipes.
• Qualified Personnel: The work must be performed by qualified and competent welders.
• CIDB Accreditation: The required CIDB grading (1CE/PE) serves as a formal recognition of the company's capability, experience, and financial standing for projects of this nature.

Important Notes on Unusual Terms

• Galvanised Flange Welding: This refers to welding on pipes that have a protective zinc coating (galvanised) and have flanged ends (a rim or collar for connecting to other equipment). Welding on galvanised steel requires specific procedures to manage the toxic fumes produced by the zinc coating.
• Bermad Valves: These are hydraulic control valves, often used in water distribution systems for pressure reduction, flow control, or level control. "Activation" likely refers to commissioning or setting up these valves to operate correctly.
• Spool Piece: A short length of pipe used to connect two other components, in this case, a 20mm spool piece to connect the level dex control valves.
