Objectives

The primary objective is to appoint a qualified contractor to conduct emergency site contamination assessments across Transnet Pipelines facilities, including pipelines, depots, and pump stations. The service covers Gauteng, Mpumalanga, Free State, and North-West provinces over a three-year period on an “as and when required” basis. The goal is to rapidly identify contamination risks to human health and the environment, determine immediate or long-term remediation needs, and develop cost-effective, sustainable cleanup strategies compliant with national environmental legislation.

Scope of Work

The contractor will perform risk-based site investigations following recognized environmental frameworks. Services include preliminary and phased site assessments, field sampling (soil, groundwater, surface water, and air), supervised drilling of monitoring wells, hydraulic testing, and accredited laboratory analysis. Deliverables encompass conceptual site modelling, human health and ecological risk assessments, stakeholder engagement, and the compilation of detailed remediation plans. The contractor must utilize multi-criteria analysis to evaluate cleanup technologies based on cost, time, complexity, and sustainability. Strict response timelines apply, requiring initial site visits within 36 hours of notification and report submission within specified working days. All activities must comply with occupational health and safety regulations and Transnet’s integrated management systems.

Technical Requirements

The contract operates under an NEC3 Term Service Contract framework, utilizing a priced Option A structure with a rate-based price list. Pricing includes escalation adjustments after twelve months, indexed to consumer prices, plant and equipment costs, and diesel fuel rates. Contractors must maintain statutory insurance coverage, including occupational injury liability and motor vehicle third-party coverage with a minimum indemnity of ten million rand. Personnel accessing restricted infrastructure must undergo security clearance screening. The agreement mandates strict adherence to data protection legislation, confidentiality protocols, and anti-corruption integrity pacts. Evaluation follows an 80/20 or 90/10 preference point system prioritizing price and Broad-Based Black Economic Empowerment status. Electronic submission through a designated procurement portal is mandatory, with no paper bids accepted.

Skills and Personnel Requirements

Tenderers must demonstrate proven company experience, submitting evidence of at least three completed projects involving soil and groundwater contamination assessment and remediation planning within the past seven years. Key personnel must hold valid registration with the South African Council for Natural Scientific Professionals. The required team includes a Principal Geohydrologist, two Senior Geohydrologists, two Junior Geohydrologists, a Wetland Assessment Specialist, and an Aquatic Ecologist. Each role demands specific academic qualifications in hydrology, geology, environmental science, or biological sciences, alongside defined minimum experience thresholds ranging from one to seven years depending on seniority. Comprehensive curricula vitae detailing relevant project history, technical responsibilities, and duration of service must accompany the submission.
