The Nelson Mandela Metropolitan Municipality aims to procure a competent contractor to execute waterproofing works across municipal properties and infrastructure. The primary objective is to eliminate water ingress, preserve structural durability, extend asset lifespans, and minimize future rehabilitation expenditures.

Scope

The tender covers comprehensive waterproofing services for municipal buildings and related structures. While exact locations, quantities, and technical specifications are detailed in the official tender package, the scope typically includes substrate preparation, application of approved waterproofing systems, detailing around joints and penetrations, and compliance testing. All work must align with municipal construction standards and the specifications provided in the formal documentation.

Technical Requirements

• Contractors must hold a minimum Construction Industry Development Board (CIDB) grading of 1GB or higher.
• Bids must be prepared and submitted exclusively using the municipality's official tender documentation.
• Strict compliance with prescribed procedures for sealing, addressing, physical delivery, and submission timing is mandatory.
• Emailed and late tenders will be automatically disqualified.
• A compulsory clarification meeting is scheduled for 19 October 2026 at 11h00 at Brister House, Govan Mbeki Avenue, Gqeberha.

Skills Requirements

The mandated CIDB grading indicates that the contractor must maintain an operational capacity and workforce suitable for municipal-scale construction. Required competencies include:

• Certified project managers experienced in public sector procurement, reporting, and compliance
• Licensed site supervisors and foremen with proven track records in building envelope protection
• Skilled waterproofing technicians proficient in membrane installation, liquid-applied systems, and joint sealing
• Occupational health, safety, and environmental officers to ensure workplace and regulatory compliance
• Quality assurance personnel capable of conducting material inspections, adhesion tests, and flood/water testing

Explanation of Technical Terms

CIDB Grading 1GB: The Construction Industry Development Board (CIDB) classifies South African contractors based on financial turnover, project history, and technical capability. Grade 1GB is a high-tier classification authorizing contractors to manage large, complex general building projects, typically with contract values exceeding R50 million. The "G" suffix denotes general building works, while "B" confirms the contractor has satisfied stringent performance, financial stability, and regulatory standards required for significant municipal infrastructure contracts.
