Objectives

The primary objective is to safely eliminate health hazards associated with asbestos-containing building materials by executing controlled demolition and removal, followed by the installation of compliant, non-asbestos alternatives across multiple Randwater depot and pump station facilities.

Scope of Work

The project spans numerous operational sites including Benoni, Esselen Park, Bloemendal, Brakpan, Forest Hill, Germiston, Krugersdorp, Libanon, Waterval, Wildebeesfontein, Meyerton, and Amanzimtoti. Core deliverables include:

• Demolition and safe removal of asbestos cement walls, barge boards, fascia boards, corrugated roof sheetings, ceiling panels, and pillar/column shells.
• Replacement with specified non-asbestos materials, including IBR roofing sheets, cement-based boards, and structural concrete elements.
• Establishment and ongoing maintenance of a site camp throughout the construction period, encompassing offices, meeting rooms, sanitation, water, and electricity.
• Provision of site security, project supervision, environmental management, quality control, and community liaison services.
• Full adherence to the Occupational Health and Safety (OH&S) Act and Construction Regulations, including all required insurances and statutory contributions.

Technical Requirements

Bidders must demonstrate proven capability to manage high-risk asbestos abatement alongside concurrent construction activities. Required technical competencies include:

• Execution of engineered asbestos removal methodologies to prevent airborne fibre dispersion, incorporating wet suppression techniques, sealed containment zones, and certified hazardous waste packaging.
• Proficiency in installing alternative building systems, specifically profiled metal roofing, cement fibre cladding, and casting structural concrete into existing pillar forms.
• Multi-site logistical planning covering temporary infrastructure deployment, utility integration, material staging, and secure perimeter control.
• Comprehensive environmental management plans addressing dust suppression, spill prevention, tracked waste transport, and disposal at licensed facilities.
• Documented quality assurance procedures with mandatory hold points for demolition clearance, replacement installations, and concrete strength verification.

Skills Requirements

The appointed contractor must mobilise a certified, multidisciplinary workforce capable of delivering complex abatement and construction works simultaneously. Essential personnel and qualifications include:

• Licensed asbestos removal operatives trained in South African OH&S standards and hazardous material handling.
• Certified project manager and site supervisor with demonstrated experience in distributed infrastructure programmes.
• Qualified environmental officer to oversee compliance monitoring, waste chain-of-custody documentation, and mitigation implementation.
• Dedicated quality controller responsible for material inspections, installation verification, and record-keeping.
• Community liaison officer to facilitate stakeholder communication and resolve local interface issues.
• Skilled tradespersons including carpenters, roofers, concreters, and general builders for replacement and finishing works.

Notes on Unusual or Complicated Terms

• Asbestos Cement Materials: Building products containing chrysotile asbestos fibres bound in cement matrix. Require specialised containment, respiratory protection, and regulated disposal due to severe carcinogenic risks when disturbed.
• IBR Roofing Sheets: Acronym for Indented Box Rib, a profiled steel roofing system widely adopted as a durable, lightweight, and non-asbestos alternative to traditional corrugated sheets.
• Cast 25 MPa Concrete: Structural concrete specified to achieve a minimum compressive strength of 25 megapascals after 28 days, utilised to permanently fill and reinforce replaced pillar/column shells.
• P&G (Preliminary and General): Standard construction billing classification covering site setup, regulatory compliance, overheads, and time-related resources rather than direct physical construction items.
