Project Value: ZAR 8.4 Billion

King Shaka International Airport (KSIA) is the first major green field airport to be developed on the African continent for 40 years. The decision was taken to relocate airport operations from the old Durban International Airport south of Durban to a green field site north of the city with a view to providing an initial capacity of 7.5MAP, expandable up to a future ultimate capacity of 45MAP. Osmond Lange was invited by Ilembe (Pty) Ltd, a consortium of building contractors formed to bid for the design-and-build contract for KSIA, to assemble and lead a group of Architectural firms and specialised sub-consultants. The scope of work included the design of more than 70 buildings, the largest and most significant of which is the 103 000m² six level terminal building.

The terminal is divided into two main elements:

  • The processor that accommodates all the facilities to process passengers and baggage as well as the retail, administration and technical spaces.
  • The Airside Corridor that constitutes the circulation route and interface element between the Processor and the aircraft.

Structurally the building is designed with a combination of a conventional reinforced concrete frame with 15 x 15 spans and a long span steel roof. This approach allows for economy, speed of construction and the provision of large, column free spaces at the upper level public areas. It also facilitates the incorporation of roof monitors designed to bring natural light into the building.

As the IAJV leader, Osmond Lange was responsible for the management of the Joint Venture including:

  • Design leadership
  • Management and Interface with the JV member firms at design and administrative level
  • Interfaces with Client, Contractor, Local Authorities and ACSA (Airports Company South Africa)
  • Interfaces with Consultants of all disciplines involved in the project
  • Management of the Passenger Terminal building Design and Documentation team
  • Programming, Reporting and press releases
  • IAJV financial management
  • Quality Assurance
