Geometric design


Authorities are increasingly shifting their emphasis from road alignment safety and economic designs to requiring environmental impacts, socio-economic impacts and proof that roads will be constructed using labour intensive construction methods, in line with the Expanded Public Works Program (EPWP). SSI’s geometric designers are committed to adhering to the requirements of these authorities and we have introduced a specialist service to assist clients in the field of geometric design of roads and railway. 

The services we offer in this arena can be combined into a comprehensive project, or implemented on a menu basis — or individually — to suit clients’ needs. Our offering includes: Route determination for roads and railway

  • Design of freeways and urban roads
  • Design of rural roads
  • Vehicle terminals (taxi ranks, bus ranks, traffic control centres etc)
  • Design of internal and external township roads
  • Road stormwater drainage management
  • Design of railway lines
  • Design of airport runways, taxiways including  rapid exit taxiways (RETs) and holding bays, using ICAO Annexure 14
  • Drawings
  • Project cost estimating
  • Contract documents and materials specifications
