KeNHA Highway Maintenance Works: Planned North and South Rift Road Upgrades

The Kenya National Highways Authority (KeNHA) has requested bids for its fourth-quarter financial year 2025-2026 road asset preservation cycle, focusing heavily on critical links within the Rift Valley network. Funded via the Road Maintenance Levy Fund, these interventions target long-term pavement stability.

In the North Rift region, the authority has structured performance-based contracts for the maintenance of the Nyaru to Kamwosor (B77) road and the Chesoi to Kilangata (B15) road. Both projects require National Construction Authority (NCA) registration categories 4, 5, or 6.

Mandatory site visits begin at Nyaru Market Centre on July 1, 2026, followed by the Chesoi route later that afternoon. Concurrently, separate framework emergency handling contracts have been issued for the lower and middle sub-regions to manage sudden carriage failures.

A mandatory pre-bid conference for these North Rift emergency frameworks is scheduled for June 30, 2026, at the regional boardroom in Eldoret. Contractors tracking these packages must deploy a technical representative holding a minimum of a diploma in civil or highway engineering.

South Rift infrastructure deployments target routine maintenance and spot improvements on the Ngata to Njoro via Ndeffo (B18) road and the adjoining Ndeffo to Mau Narok section. The former project is open, while the latter is reserved for Persons with Disabilities (PWD).

Site briefs for the B18 corridor kick off on June 30, 2026, sequentially moving from the Njoro Interchange to Ndeffo town. Contractors must ensure their site representatives possess certified academic papers and current registration certificates with local engineering regulatory bodies.

Further South Rift packages include performance-based maintenance for the Londiani to Fort Tenan (B132) route and the KCC Sotik to Ndanai via Gorgor (B133) road. These projects require NCA registration categories 5, 6, or 7, targeting women and youth respectively.

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 automated disqualification.

Furthermore, directors with active, ongoing construction projects as of the opening date are locked out. 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 the downloaded files will not be accepted as a valid form of serialization, demanding completely fresh sequential numbering instead.

Bidders must submit an original introductory letter bearing the official company letterhead and a stamp authorizing their representative. All academic certificates and national identity documents presented during the mandatory pre-tender site activities must be formally certified by a commissioner of oaths.

Final physical submissions for the North Rift tenders close at the Eldoret regional office, while South Rift proposals must be securely locked into the Nakuru office tender box by July 16, 2026, at 11:00 AM.
