Road Safety Audit Expert for design of Kericho-Kenegut border road and design of associated civil works for Fibre Optic Cable for design build project delivery (110 km)

CONSULTANCY SERVICES FOR FEASIBILITY STUDIES AND PRELIMINARY ENGINEERING DESIGN OF KERICHO-AINAMOI-POIYWEK-CHEPKOIYO-KOISEGEM-FORT TERNAN-GILIMORI-KENEGUT BORDER ROAD AND ENGINEERING DESIGN OF ASSOCIATED CIVIL WORKS FOR FIBRE OPTIC CABLE FOR DESIGN BUILD PROJECT DELIVERY (110 KM)

 

Project Description

The project corridor, known as the Great Highlands Connectivity Corridor (GH-CC), connects some of Kenya’s most productive agricultural zones and key rural service centres across Kericho, Kisumu, and Nandi Counties. The specific road sections under this assignment (approx. 110 km) are detailed below:

 

Roads for Rural Economic Development Project (RREDP), Great Highlands Connectivity Corridor: Kericho – Kenegut road section
S/No.	Road Section	Length (Km)	Counties Traversed
1.	Kericho Township – Ainamoi – Chepkoiyo – Koisegen	37.4	Kericho, Kisumu, Nandi
2.	Fort Ternan – Gilimoro – Kenegut Border	38.6
3.	Associated Spur roads	34.0
Total		110 Km

The existing corridor consists of low-standard earth and gravel sections, interspersed with short paved stretches. The route serves intensive agricultural areas, specifically tea estates, dairy belts, and grain zones, but its deteriorated condition limits reliable access to processing facilities and markets. In Kericho and Nandi Counties, the existing road geometry and drainage are inadequate for the steep gradients and high rainfall, leading to erosion, surface rutting, and shoulder loss.

The project aims to upgrade these roads to appropriate bitumen standards to enhance rural mobility, economic inclusion, and traffic flow. Additionally, the project will integrate the design of associated civil works for Fibre Optic Infrastructure to enhance digital connectivity in the region.

 

 

1          OBJECTIVES OF THE ASSIGNMENT

1.1        Main objectives

The primary objective of this consulting assignment is to develop comprehensive preliminary engineering design and draft bidding documents for the Kericho – Koisegem – Fort Ternan-Kenegut Border Road corridor. The assignment delivers design work to support Kenya National Highways Authority. The specific objectives are organized into five complementary areas addressing technical design, economic evaluation, procurement preparation, decision support, and stakeholder coordination.

1.2        Specific objectives

In particular, the study will include (but not be limited to) the specific objectives listed below:

1.        Fibre Optic Mapping: Inspect and map out the location of existing fibre optic cables (if any) and utility corridors along the road alignment in consultation with the ICT Authority and relevant Service Providers to determine the optimal route for new infrastructure.

2.        Traffic and Economic Modelling: Conduct comprehensive traffic surveys (motorized and non-motorized) and rigorous economic modelling to determine if the project's Economic Internal Rate of Return (EIRR) and Net Present Value (NPV).

3.        Alignment and Scope Optimization: Identify the optimum road alignment and fibre optic route that maximizes Economic Internal Rate of Return (EIRR) while minimizing Land Acquisition as well as Social and Environmental impacts, with decision gate at Month 4 through Preliminary Concept Design Report presenting three evaluated alternatives enabling Kenya National Highways Authority to select preferred design approach.

4.        Preliminary Engineering Design: Develop a Preliminary Engineering Design defining the horizontal/vertical alignment, typical cross-sections, and pavement structure sufficient to freeze the Right of Way (RoW) and define the Employer's Requirements and functional specifications for a future FIDIC Plant & Design-Build (Yellow Book) contract.

5.        Project Risk Structuring: Formulate a comprehensive Project Risk Matrix and Project Risk Management Framework (Technical, Financial, Environmental and Social) to guide the risk allocation between the Employer and the Contractor in the future Design-Build contract.

6.        Cost Estimation: Prepare a confidential, highly accurate Engineer's Cost Estimate and Unit Rate Analysis.

7.        Procurement Documentation: Prepare comprehensive Employer's Requirements and draft bidding documents incorporating all environmental and social safeguards findings available during Phase 1, with documents structured for Kenya National Highways Authority.

8.        Stakeholder Engagement Support: Support the Client in technical coordination and stakeholder engagement activities (public consultations, county government meetings) required for project appraisal.

9.        Training and Capacity Building: Provide structured on-the-job training and capacity building for nominated KeNHA, KURA or KERRA staff in highway design, project development, and Design-Build procurement through active participation in assignment activities.

2         SCOPE OF SERVICES

2.1  Feasibility Studies & Preliminary Engineering Design Tasks

Estimated Duration: 8 Months

The Consultant shall:

•      Review existing data, maps, and studies to identify critical gaps and validate the project concept.

•      Conduct a physical inspection and mapping of existing fibre optic cables and utility corridors along the road alignment in consultation with the ICT Authority to prevent conflict and determine the optimal route for new infrastructure.

•      Carry out detailed field investigations (Traffic, Topographical, Geotechnical, Hydrological) and Economic Analysis to determine the optimum intervention that balances economic viability (EIRR/NPV) with social and environmental sustainability.

•      Develop the Preliminary Engineering Design (horizontal/vertical alignment, typical cross sections, pavement structure, drainage, and fibre duct locations).

•      Formulate a Project Risk Framework and Risk Matrix identifying technical, geological, and financial risks to be allocated between the Employer and Contractor in the future FIDIC Yellow Book contract.

•      Prepare a confidential Engineer’s Cost Estimate (separated into Road Works and Fibre Optic Civil Works).

•      Prepare Employer's Requirements, Initial Selection Document and Request for Proposals translating the Preliminary Engineering Design into performance-based specifications and procurement documentation suitable for Design-Build contractor selection.

•      Conduct a Road Safety Audit of the Preliminary Engineering Design using internationally recognized approaches and standards, with findings shared with the Director (Highway Design and Survey, KeNHA) and the National Transport and Safety Authority, and recommendations incorporated into the final Preliminary Design Report.

•      Provide structured on-the-job training and capacity building for Kenya National Highways Authority, Kenya Rural Roads Authority, and Kenya Urban Roads Authority counterpart staff through active participation in assignment activities, covering survey operations, traffic analysis, pavement design, economic evaluation using HDM-4, environmental considerations, Design-Build procurement, and technical report preparation.
