Transport

South Africa has a modern and well-developed transport infrastructure. The road and rail networks are the longest on the continent, and the country’s ports provide a natural stopover for shipping from around the world. The transport sector has been highlighted by the government as a key contributor to South Africa’s competitiveness in global markets and is regarded as a crucial engine for economic growth and social development. JG Afrika is committed to being part of this drive to connect people and goods, and has extensive service experience of roads, railways, traffic and transportation, and pavement management.

Our transport and traffic engineers have vast experience of involvement with transport studies for renewables energy projects (wind energy, solar PV, CSP, biogas, waste-to-energy). Transport studies are an integral part of the application process of any renewable energy project, as they include the investigation of feasible routing from port of entry to site, feasible haulage vehicles, accessibility to the project site, correspondence with the authorities and the project team, input into internal access roads, impact on external roads and assessment of risks along the transport routes. Our transport engineers offer comprehensive and experienced input into the implementation of a renewable energy project.

Traffic and Transportation

Transport Risk Assessments, including logistics aspects, route limitations, permitting.
Transport Impact Studies as part of an Environmental Impact and/or Basic Impact Assessment process.
Input into site internal access road layouts and laydown areas
Investigation of suitable access points from a transport planning perspective
Correspondence with relevant Authorities for approvals.

Pavement management systems apply a set of systematic procedures to assess alternatives and by predicting future performance they enable clients to make better investment decisions for pavement maintenance, preservation, rehabilitation and replacement. Such systems employ a mix of historical construction/material data, ongoing on-site road testing and specialised software to generate useful, reality-based information for decision makers.
