The Sumbawanga–Matai–Kasanga Port Road (150km) project is a complex highways project in Tanzania funded by the World Bank with an overall value of €75m.

Very extensive contract commercial strategy and advice was provided by Nicholas O’Dwyer for the overall project, including technical assistance and training for the employer. Our involvement comprised extensive procurement advice by way of workshops to consider the appropriate delivery model and contract form.

The main construction constituents of the road include;

  • double surface dressing treatment (20mm and 10mm chips),
  • 150mm thick crushed rock base course,
  • 200mm Class C1 stabilized sub-base natural gravel,
  • 150mm thick G:15 natural gravel sub-grade layer, and,
  • various new bridges, box culverts and pipe culverts.

Supervision of Matai Town roads urban construction included, pavement, relocation of utilities, town drainage, footpaths. It was considered that due to the extensive geographic scale of the project, and the technical challenges associated therein, that from a cost and risk management perspective that the project should be delivered by way of two separate lots with separate commercial and supervision teams provided by Nicholas O’Dwyer.

Upon preparation of a contract and procurement strategy report it was ultimately recommended and decided that two separate contractors be procured by way of the FIDIC Silver Book (Conditions of Contract for EPC/Turnkey Projects).
