ell the best experience i have seen is to let somebody organize everything for you . there are people who know how to do just that and you will have stress free building experience. definitely you need an expert in building coz you aren't that which you will pay your contractor might be less that the loss you might cause by your shoddy contracting .yes i understand you need to do cost saving but at what cost ? weigh the two option sand see hireign acontactor is the bestw ay

Assuming you have the land, approved plans and money to start this is how its done. 1.Get one good hardware,not exactly the one everybody is going,be a friend you wil know why later. 2. Don't contract anybody even the head fundi,let all be casuals,payed every sat. 3.Head fundi is 1000/day, fundi is 800/day, mtu ya mkono 400/day. 4.One site guy cum storeman alias wachie 24 hrs 6500/month 5.Never carry more than 2K with you pay using mpesa,unless after site u plan to go for a drink @ matasia Forget the 1/2 A million he is asking.

I agree with @Ngong above. During Koroga(Foundation and slab), the fellows might ask for 100 shillings more which is fine. Be careful with trench digging coz they also overcharge though it also depends on how deep they have to dig to reach murram.Roofing, plumbing and electrical wiring is better contracted but do not engage a broker, just contract the guy doing it with his watu ya mkono. If digging septic, get a reliable guy coz many disappear when they reach hard rock.

Thanks Captain! I did not know that there are brokers for electricians/plumbers/roofers! Thanks for the warning.

whats your construction cost per square metre ?
