KeNHA Highway Maintenance Works: Planned Nairobi and Central Region Road Upgrades

The Kenya National Highways Authority (KeNHA) has requested bids for its fourth-quarter financial year 2025-2026 road asset preservation cycle, targeting critical links within the Nairobi and Central region networks. Funded via the Road Maintenance Levy Fund, these interventions target long-term pavement stability.

In the Nairobi region, the authority has structured performance-based contracts for the maintenance of the Bomas to Kiserian (B19) road and the Kiambu to Ngewa (B30) road. The former requires National Construction Authority (NCA) registration categories 2, 3, or 4, while the latter requires categories 3, 4, or 5.

A further Nairobi package covers performance-based maintenance of the Naivasha junction to Njabini (B109) road, reserved for youth contractors holding NCA categories 5, 6, or 7. A separate contract targets road lighting maintenance on the Kikuyu-Ndenderu-Ruaka Western Bypass (B115/B33), requiring NCA categories 1 or 2 for electrical works alongside a valid Energy and Petroleum Regulatory Authority (EPRA) Class A or B licence.

Mandatory pre-tender site visits for the Nairobi packages run from June 30 to July 3, 2026, with venues ranging from near Galleria Mall on B19 to the Gitaru Interchange on the Western Bypass. All site visits are coordinated through the KeNHA Nairobi Regional Office on Machakos Road, Industrial Area.

In the Central region, performance-based maintenance works are tendered for the Muranga to Sagana (B25) road, reserved for youth contractors, and the Ol'Kalou to Nyahururu (A4) road, which includes a safety enhancement footbridge across the Ngare Naro river and is reserved for women. Both require NCA registration categories 5, 6, or 7.

Pre-tender site visits for the Central packages take place on July 2 and 3, 2026. The Ngare Naro bridge site visit begins at the bridge along the Ol'Kalou to Nyahururu road, while the Muranga to Sagana visit starts at the B114/B25 junction in Murang'a. Central region submissions are managed through the KeNHA Central Region offices along Classic-Kiandu-Othaya Road in Nyeri.

Across both regions, bidders must navigate a strict market equity rule where companies can contest up to two tenders but can only walk away with one contract award. Bidding across multiple firms or exceeding the two-tender limit triggers automatic disqualification.

Directors with active, ongoing construction projects as of the tender closing date are not eligible to bid. Financial proposals must align strictly with prevailing market rates to pass the initial evaluation stages before final selection.

Prospective firms are required to sequentially serialize all pages of their tender documents. The authority emphasizes that standard pagination from downloaded files will not be accepted as a valid form of serialization, demanding completely fresh sequential numbering instead.

Every site visit representative must carry an original introductory letter on official company letterhead bearing an authorizing stamp. All academic certificates and national identity documents must be formally certified by a commissioner of oaths before the mandatory pre-tender site activities.

Final physical submissions close at the respective KeNHA Nairobi and Central regional offices on July 16, 2026, at 11:00 AM.
