Objectives

The primary objective of this tender is to secure a qualified contractor to supply, deliver, and commission laboratory extraction fan systems for Johannesburg Water. The initiative aims to establish reliable, high-performance ventilation infrastructure that meets strict laboratory environmental, safety, and operational standards.

Scope

• Supply: Provision of complete laboratory extraction fan systems, including motors, housings, controls, ductwork interfaces, and all ancillary components required for full functionality.
• Delivery: Secure transportation of equipment to specified sites, including handling, storage, and coordination with site logistics.
• Commissioning: On-site testing, performance verification, airflow balancing, and integration support to ensure systems operate within specified parameters before formal handover.
• Compliance & Documentation: Strict adherence to official tender documentation, submission protocols, sealing/addressing requirements, and participation in scheduled clarification sessions.

Technical Requirements

• Laboratory Extraction Fan Systems: Industrial-grade ventilation equipment specifically engineered to safely remove hazardous fumes, particulates, heat, and moisture from controlled laboratory environments. These systems must maintain consistent negative pressure, comply with acoustic limits, and integrate with existing building management or exhaust networks.
• Commissioning Process: A structured procedure involving pre-start inspections, motor rotation checks, vibration analysis, airflow measurement, filter/load testing, and performance certification against design specifications.
• CIDB Grading 1SO or Higher: The Construction Industry Development Board (CIDB) grading system certifies contractor capability. A 1SO designation indicates verified competency in specialized mechanical and electrical installations, particularly for complex ventilation, environmental control, and utility infrastructure projects.
• Regulatory Compliance: All equipment and installation activities must align with South African National Standards (SANS), occupational health and safety legislation, and municipal electrical/mechanical regulations.

Skills Requirements

• Proven track record in procuring, installing, and commissioning laboratory or industrial ventilation systems.
• Access to certified mechanical and electrical technicians capable of system alignment, airflow balancing, fault diagnostics, and preventive maintenance planning.
• Project management expertise to coordinate delivery schedules, site access, stakeholder communication, and commissioning timelines.
• Ability to interpret technical specifications, respond to clarification queries, and deliver comprehensive as-built drawings, operation manuals, and staff training upon completion.
• Financial and operational capacity to sustain project execution without delays, supported by appropriate insurance, warranties, and after-sales service commitments.
