Why It Matters

Poor Road Infrastructure Costs Kenya Billions Annually

Inadequate transportation infrastructure limits economic growth, raises logistics costs, and puts communities at risk. Choosing the wrong engineering consultant compounds these problems — through poor designs, failed pavements, and cost overruns. Strasan Group exists to solve these problems at every stage of the project lifecycle.

Substandard Designs

Poorly conceived road alignments and inadequate pavement structures fail prematurely, requiring costly rehabilitation within years of construction — wasting public and private investment.

Environmental & Regulatory Non-Compliance

Roads built without proper ESIA documentation expose clients to regulatory penalties, project shutdowns, and reputational damage with government and community stakeholders.

Inadequate Construction Oversight

Without qualified resident engineers on site, contractors cut corners on materials and workmanship — resulting in defective roads that fail quality and safety standards.

FAQ

Common Questions About Our Transportation Engineering Services

Answers to the questions we hear most from clients planning road and highway projects in Kenya and East Africa.

Is an Environmental & Social Impact Assessment required for all road projects in Kenya?

Yes. Under the Environmental Management and Co-ordination Act (EMCA) and NEMA regulations, any project with potential significant environmental or social impacts — including road construction — requires an ESIA licence before works commence. Strasan Group's NEMA-licensed Lead EIA/EA Expert manages this process, from scoping through public participation to final NEMA approval, ensuring full statutory compliance and protecting your project from regulatory delays.

How long does a feasibility study and engineering design take for a typical access road?

For a typical access road project (up to 5 km), the complete design process — including topographic survey, geotechnical investigation, drainage design, pavement design, drawings, BoQs, and tender documentation — typically takes 8–12 weeks. Timelines vary with project complexity, terrain, and regulatory processes. We provide a detailed programme at the outset of every assignment.

Can Strasan Group handle road projects outside Kenya?

Absolutely. We have successfully delivered transportation engineering projects in South Sudan, Somalia, and Ethiopia, and we actively pursue assignments across East and Central Africa. Our team is experienced in working with bilateral and multilateral development partners, national road authorities, and private clients in the region.

Do you handle road projects for private residential and commercial developers?

Yes — a significant portion of our portfolio consists of private estate developers and real estate investment companies. We have designed and supervised internal road networks, access roads, and drainage systems for estates in Kiambu, Nairobi, Nyeri, Meru, and other counties. We also prepare traffic impact assessments required for development approval.

What is included in your construction supervision service?

Our supervision service covers resident engineer assignment, daily site inspections, materials testing and approval, measurement of works, interim payment certificate preparation, variation order management, quality assurance and non-conformance reporting, monthly progress reports, and project close-out documentation including as-built drawings and defects liability oversight.
