Road Construction Rates Per Km In Kenya 2021

Share with friends

After publishing a comprehensive report on Kenya’s construction costs, we’ve been receiving inquiries regarding the corresponding road construction costs in Kenya. As such, we had to take the time to research extensively and prepare a guide that conclusively reveals the actual road construction rates in Kenya. 

Now, for the sake of accuracy, we didn’t limit ourselves to the road projects that Integrum has been involved in as the project managers (usually on the side of the contractor). We also pulled data from the Kenya National Bureau of Statistics (KNBS), Kenya Roads Board (KRB), Kenya National Highways Authority (KeNHA), Kenya Urban Roads Authority (KURA), and Kenya Rural Roads Authority (KeRRA). 

Here’s what we ultimately established…

How Much Does It Cost To Build Tarmac Road Per Km? 

Ok, sorry to say, but there are no standard road construction costs in Kenya. Rather, the cost of constructing 1 km of tarmac road ranges from Kshs 26.12 million in some projects to as much as Kshs 903.37 million per km in other projects. 

Yeah, we know – that’s a pretty huge variation. You see, when it comes to road construction, the precise project costs depend on multiple factors – such as the type of construction materials used, terrain and soil conditions, road class, road design, drainage,  etc. 

Superhighways (S) and International Trunk Roads (A), for instance, typically attract the highest road construction rates per km because they’re designed to withstand heavy traffic and loads. National Trunk Roads (B) on the other hand, are usually cheaper – while Primary Roads (C) and Seconds (D) generally have the lowest road construction rates in Kenya. 

We figure it can be hectic keeping up with all these rates. So, to simplify everything for you, we’ve broken down the costs of recent road construction projects into their respective rates per km. This should help you get a good idea of how much it’ll cost to build a specific type of road in 2021. 

Otherwise, here’s even an additional guide on how much the project engineers earn in Kenya.

If you’re a road contractor, though, you can get in touch with us for an accurate analysis of the tendering rates, based on all your project parameters.

Overall, to accurately estimate the cost of your road construction project, you have to take the following into consideration: 

  • Surveying costs. 
  • Land acquisition costs. 
  • Setting out costs – including road staking, felling, forming, and clearing. 
  • Rock blasting costs. 
  • The costs of the earthworks – including gravelling, grading, and compacting. 
  • Gravel crushing costs. 
  • Paving costs. 
  • Surfacing costs. 
  • The costs of environment protection works – including soil stabilization, retaining structures, and bridges. 
  • Miscellaneous costs – such as the transport and delivery of items. 
  • Machine costs. 
  • Project servicing costs. 

That said, feel free to raise any questions you might have regarding your road construction project, and we’ll be glad to help. Integrum’s engineers are extensively experienced in managing road construction projects on behalf of contractors.

This is an excellent summary of the major costs in a road construction, which usually varies from project to project depending on natural, physical, climatic, environmental, social, financial and other constraints that must be overcome for the project to be successfully delivered.

You could also talk about some of the road projects in Kenya that have had cost overrun during construction.
