Minus the cost of steel and cost of formwork and minus the size of slab since ground floor slab is usually 100mm thick compared to suspended slabs which are 150mm thick.

Thanks, gives me a rough idea of what to expect cost wise.

@vky, thanks.

In construction, the process is same the world over . You start by
1. appointing architect
2.appointing qs
3.appointing structural engineer
4.appointing services/electrical engineer
5. appointing contractor
6. all the above work together in supervising and constructing the building till completion.

You dont start to deal with an electrician before you have the desings in place which are to be done by the electrical engineer in colaboration with the rest of the consultants.

Bodies that regulate construction begin with the consultants. i.e the electrician can not be professionally liable if the client has not appointed a registered electrical engineer of building services for supervision.
If you follow the above process, everything will work perfectly.
Inbox me for contacts of an electrical engineer/services engineer. Once he is in place, he should be able to advice/source/supervise the electrician to perfection.

@a4architect, great stuff going on in here, now i am about to proceed with a project where i am putting up a three storey building with eight two bedroom units, i have everything else sorted but would like to hear your take on dealing with electricians in terms of contracts, costs and may be a reference to a good electrician. lastly are there bodies that regulate electricians or electrical companies


You have in mind what I am thinking. What is your estimated costs?

Perfect, calculation was around 55 bags, used up around the same amount.

this is one thread which will be useful to me in August 2013 God willing. my 10ftby 10 ftby 10ft septic tank is underway.digging expected to cost 12k.
I will complete the septic tank so that the soil doesn't fill up back.hopefully by May.a budget of 40k should suffice for the complete septic tank.next will be excavating the site black cotton soil layer of about 2ft deep to the rocky layer where the house foundation will begin. 30k should be enough for the excavation.
drawings to be done by June though I have conceptualized what I need .my Fundi has been of much help but will involve the experts when I'm ready .just preparing the ground as a motivation to keep focused.

I have seen that I will never have the hundred of thousands that are mentioned in this thread in my pockets so I decided to go bit by bit in the construction as I build up my saving on the other side.
I already have a friends drawings which I intend to replicate and get approved by the county council.already have contacts there who advised me to start breaking the ground and accumulating the materials.



Hi there ,

please note the slab for 10 by 10 will be more expensive ( and trickier) than a 6* 8 . Given that it will cost you 12k , i guess the cost of excavating deeper might be cheaper than the broader slab for covering the septic tank. Agin 10 feet depth might not be suitable for letting the fluids soak to the ground as it will be too near the surface. just my two cents


My Fundi had advised a septic tank of a lesser width for the same reason you've stated but I decided to do similar size to my neighbors. makosa imefanyika.
but the rock underneath is hard and of good quality for the foundation according to the Fundi. these can be excavated and used for the main house foundation.I will dig deeper and get this gold to mitigate on the higher cost of the septic tank slab.
where can I get quality metal bars for the slab at the best price in town?

hope i am not replying too late . got caught up in work and hustling on the side. You need to consult a structural engineer on the reinforcement bars . As for the material coming out of the septic tank excavation, you are more likely going to use it as hardcore rather than foundation stone ..

Bwana architect ,both slabs are usually designed to be 150mm in depth though in practice, the fundi tends to advise the client " ii unaweza weka 4 inches tuu"

a shallower, wider soak pit is better than a deeper one since soak pits work by soaking the waste into the upper part of the soil that is spongy and evaporating the rest into the atmosphere. A deep soak pit might get bogged hence blockage to the septic tank outlet.
