Overall Objectives

Replace ageing fire protection infrastructure at the Witbank Depot and across Transnet Pipelines facilities with a modern, fully compliant system. The project prioritises zero OHS incidents, uninterrupted 24/7 operations, and strict compliance with South African regulations. It establishes a standardised, risk-based framework ensuring life safety, asset protection, and reliable mitigation of credible fire events while integrating seamlessly with existing operational controls.

Scope of Work

Deliver a complete Engineering, Procurement, and Construction (EPC) package encompassing detailed design, supply, installation, testing, commissioning, and handover. Core components include water and foam concentrate storage tanks, duty/standby diesel and electric pump-sets, jockey pumps, balanced-pressure foam proportioning systems, expanding plug and non-return valves, tank cooling rings, fire department interfaces, extensive stainless/carbon steel and HDPE piping networks, low-voltage switchgear, control panels, cabling, racking, trenching, and earthing infrastructure. The scope also covers demolition and relocation of obsolete systems, stormwater upgrades, geotechnical investigations, civil/structural works, pipeline bedding practices, and operator training. All activities must occur within a live, hazardous fuel-handling environment with minimal operational disruption.

Technical Requirements

• Design & Standards: Compliance with SANS, ASME B31.3, API 650/653, NFPA, FM Global, ISO 9001:2015, and ISO 12944. Hydraulic modelling must utilise AFT Fathom 13. Designs must meet or exceed the Employer’s conceptual baseline.
• Geotechnical & Civil: Mini-pile foundations to weathered rock are mandatory due to shallow groundwater and loose soils. Earthworks require Modified AASHTO compaction using G-class granular materials, with pipeline padding restricted to fine, non-cohesive sand to prevent coating damage. Structural steel must be S355JR with 85-micron hot-dip galvanizing per ISO 1461.
• Electrical & Instrumentation: Field equipment in hazardous zones (0/1/2) must be Intrinsically Safe (IA) certified per SANS 10086-1 and SANS 60079-14. Control architecture relies exclusively on hardwired relay logic controllers (FCPs); PLCs are explicitly prohibited for pump sequencing. FCP-ECP interfaces use potential-free contacts.
• System Performance & Testing: Fire water and foam systems must sustain minimum 60-minute continuous operation plus a 10% contingency. Mandatory Factory Acceptance Tests (FAT), Site Acceptance Tests (SAT), 6-hour endurance runs, laser alignment certificates, and hydrostatic testing at 1.5× design pressure are required. Wetted components must resist foam concentrate compatibility, with corrosion protection guaranteed for 15–20 years.
• HSE & Operations: Strict breathalyser testing, flame-retardant PPE, hot-work permits, wind limits (<30 km/h), and off-site pre-fabrication to eliminate hot work above product tanks. Vibration monitoring during pile driving is compulsory. Documentation must follow centralized EDMS platforms with strict naming conventions and revision tracking.
• Contract Framework: Governed by NEC3 Engineering and Construction Contract (Option A), utilising an activity schedule for milestone-based payments.

Skills & Qualification Requirements

• Company Grading: Minimum CIDB 9ME contractor designation.
• Project Manager: SACPCMP PrCPM or PMI PMP certification, NQF Level 6 qualification, and 14+ years managing multi-disciplinary petrochemical projects (minimum one valued at R200 million).
• Lead Engineers: ECSA Pr. Eng (Mechanical & Electrical) with 10+ years post-registration experience in fire-protection design, hydraulic analysis, and hazardous area installations.
• Construction Manager: NQF Level 6 qualification and 10+ years multi-disciplinary construction management experience.
• Quality Control Manager: SAIW Level 2 certification, ISO 9001:2015 QMS auditing qualification, and 15+ years in petrochemical projects, skilled in NDT interpretation and Dry Film Thickness (DFT) measurement.
• Health & Safety Manager: SACPCMP CHSM registration or NEBOSH International Diploma/BTech in Safety Management, and 10+ years implementing HSE systems.
• Lead Planner: Microsoft Projects Advanced certificate and 10+ years scheduling multi-disciplinary projects (minimum one valued at R100 million).
• Specialists: Certified welders (ASME IX/SANS HDPE), licensed electricians/instrument technicians, commissioning engineers, trained demolition crews, and document controllers experienced in EDMS administration.

Key Technical & Contractual Terms

NEC3 ECC Option A: A priced contract model where payment is released only upon verified completion of predefined lump-sum activities listed in an activity schedule.
MHI (Major Hazard Installation): A South African regulatory classification for facilities storing large volumes of flammable substances, triggering stringent safety and emergency response controls.
HAZOP: Hazard and Operability Study, a structured risk assessment methodology used to identify potential failures in process designs.
ALARP: As Low As Reasonably Practicable, a risk principle requiring hazards to be reduced until further mitigation costs grossly outweigh safety benefits.
Fail-Safe Operation: System design where loss of power or control automatically defaults components to a predetermined safe position.
Run-to-Destruction: An operational protocol where engines override normal safety shutdowns during active fire events to maintain pressure until manually halted.
B-BBEE: Broad-Based Black Economic Empowerment, a procurement scoring framework awarding preference points based on ownership, skills development, and local supplier participation.
