Southern Link

What Southern Link does

Southern Link Limited is a privately-owned Tanzanian construction and engineering firm established in 1988 and headquartered in Dar es Salaam. It holds Class 1 contractor certification in both civil and building works — the highest tier under Tanzanian regulator ERB — qualifying it to bid on the largest government infrastructure tenders. Its client base is anchored by Tanzanian government agencies, including TARURA (rural/urban roads), TANROADS (national roads, including bridge projects such as Lukuledi Bridge I and II), multiple municipal councils (Mtwara Mikindani, Iringa), Muhimbili University College of Health Science, and the National Audit Office, with a smaller private-sector engagement through Twiga Cement.

The company is vertically integrated across five operating lines: civil and building construction (roads, bridges, drainage, public utilities, and internal building systems), mining and aggregate sales from company-owned quarries (crushed stones and gypsum), building materials manufacturing (solid blocks, paving blocks, culverts, guardrails, gabion mattresses, cement), construction equipment rental, and logistics/truck hiring. This structure is intended to control supply chain costs and ensure material availability across project delivery. The company has completed over 30 projects across Tanzanian regions including Dar es Salaam, Mtwara, Iringa, Lindi, Mbeya, and Pwani.

Revenue is generated predominantly through project-based construction contracts won via competitive bidding on government tenders (one-time, milestone-based payment terms), supplemented by transactional sales of building materials and aggregates, usage-based equipment rental, and logistics services. The company is founder-owned, with no disclosed venture capital or private equity backing, and has operated continuously under the same ownership since 1988.

• Aveng Group: Aveng is a major South African construction and engineering group with diversified infrastructure capabilities across Africa. Comparable as a broader African construction incumbent, though operating at significantly larger scale and including mining, engineering, and concessions beyond Southern Link's scope.
• H Young & Co (East Africa): H Young & Co is one of East Africa's longest-established contractors (founded 1920s), delivering civil, building, and road infrastructure across Kenya, Uganda, Tanzania, and beyond.

Direct peers

Comparable as an adjacent participant in Tanzania's construction materials supply chain rather than a direct competitor, providing context on vertical-integration and supplier-buyer dynamics in the local market.
