Roads and Bridges
Roads are arguably the most dominant form of transport globally and even more so within Africa. From feasibility studies, route planning and design, to rehabilitation solutions, we have you covered.
We have undertaken road projects for government authorities and private clients – from a feasibility study for a new 100km toll route in Senegal, to the detail design of a municipal road network servicing a new 60,000 unit housing development in Gauteng. We have also successfully designed various mine haul roads as part of our mine infrastructure project appointments globally. Our heavy structures’ capability handles all forms of bridge designs, including road bridges and grade separated interchanges, pedestrian bridges and elevated service crossings.
Roads and Bridges Services include but are not limited to:
- PAVEMENT DESIGN – Surfaced and unsurfaced roads.
- GEOMETRIC DESIGN – 3D Modelling.
- STRUCTURAL ENGINEERING – Bridges; Bridge foundations; Culverts.
- ELECTRICAL – Street lighting.
- STORMWATER DRAINAGE – Drainage; Floodline analysis; Run-off calculations.
- GEOTECHNICAL INVESTIGATIONS – Pavement investigations; Soil testing; Profiling and core logging; Founding conditions.

Tema Afloa Phase 1 – Ghana
Project:
Detail Design - $220M Expressway between Accra and Tema, Ghana
The Government of Ghana urgently requires rehabilitation and upgrading of the Tema-Aflao Road. The British Government, through its
Export Credit Guarantees Department (UK Export Finance), is actively financing projects undertaken by British contractors. BHM
Construction International (UK) Ltd. applied for and obtained financing to design and construct these works using the UKEF Direct
Lending Facility, and Nurizon International was appointed for the engineering design of the project.
Scope of works on the project included:
o 17km three (3) lane per direction dual carriageway expressway and two (2) lane one-way service roads on either side;
o Four (4) interchanges / bridges;
o Bus-bays and Pedestrian bridge;
o Stormwater Drainage;
o Lighting; and
o Roadside furniture, signage, traffic control devices at interchanges and road markings.
Nimba Iron Ore, Guinea and Liberia
Project:
Preliminary Mine Haul Road Design and Geotechnical Investigation
Sable Mining Africa Ltd. obtained an iron ore mining concession in the Mount Nimba region of the Republic of Guinea, with Phase 1 of the project comprising the extraction of 3Mtpa DSO (Direct Shipping Ore) from the concession area.
Iron ore product was to be transported from the mine site to the Port of Buchanan, from where it was then to be exported.
Syferfontein Megacity Development, Gauteng
Project:
Roads and Stormwater Design: Preliminary Stage
The Gauteng Department of Human Settlements (GDHS) (Gauteng Provincial Government) released a ‘radical’ human settlements ‘mega projects’ strategy in April 2015 to cover housing development in the province over the 2014/15 – 2018/19 (5 year) period. The plan seeks to transform urban planning and coordinate housing development through the delivery of self-contained economies of no fewer than 15,000 units and up to 60,000 units (low to high income residential units), compared to previously sporadic, small and isolated developments. This is also hoped to ease housing backlog pressures.
