Properties › Re: Cost Of laying a bungalow Foundation by abdulwastecx(m): 1:40pm On Feb 23, 2015

ceejay80s:
2 bedroom flat and it will be 3 flats on that foundation, not too spacious room. 10x12 room size, don't want to spend too much money on it cos I am renting it out, what I need now is how much it will cost me to lay the foundation

assuming the following:
depth of foundation 600mm ( 3 courses of 6" block)
assuming a toilet of 6' x 4' ( 1.8m x 1.2m) and two toilwt per flat
assuming a living room of 14'x14' (4.2 x 4.2m)
assuming a kitchen of 8' x 8' (2.4 x 2.4m)
assuming a dinning of 8' x 8' (2.4 x 2.4m)

setting out should cost like N30,000

perimeter each of the room 3 x 3.6m ( 10 x 12) = ( (2x3)+(2x3.6)) = 13.2m x 2 x 3 = 79.2m
perimeter of living room/ dining for the three flats = (4.2 x 4)+(2.4 x 4) = 26.4m x 3 =79.2m
perimeter of kitchen/toilets = (2.4 x 4 ) +((1.2x2) + (1.8x2)) x 2) = 13.92m = 41.76m
total perimeter of the house = 200.16m

allowing 15% for circulation and veranda = 1.15 x 200.16 = 230.184m

depth of foundation = 600mm (2')
rate of excavation N300/m = N69,000(can be lower depending on location of building)

foundation strip footing depth and width of footing = 100mm (4''), 450mm(18'')
volume of concrete = 0.1 x 0.45 x 230 = 10.35m3
cement required using mix ratio of 1:3:6 = 1/10x10.35x1506/50 = 47bags of cement @ N200 per bag = N94,000
sand required = 3/10 x 10.35 x 1.6 = 5 tonnes of sand @ N1,600/tonnes = N8,000
gravel required = 6/10 x 10.35 x2.4 = 15 tonnes @ N8,000/tonnes = N120,000
workmanship = N40,000

foundation block = 230 x 0.6 x 10 =1380blocks @ N120/block = N165,600
cement for molter = 25bags @ N2000/bags = N50,000
sand = 5 tonnes = N8,000
workmanship = N70,000

filling and compaction to DPC level: depending on site conditions

DPM = N8,000
DPC of 75mm thick = 185 x 0.075 = 13.875m3
cement = 40bags = N80,000
sand = 15 tonnes = N24,000
gravel = 5 tonnes = N40,000
workmanship = N40,000

formwork for the DPC = N20,000

SUM = N850,000 ( MINUS CONTINGENCY)

Sir,
what if u are building in a water log area, can one do soak away first and use the sand to fill foundation?

Thank you.

fill your foundation with laterite soil, since the cut away from a water lodge area contain mostly of clay soil which expand and contract at different temperature and season.

idris4r83:
of what use is quantity without quality? Try nailing a wall that is built with hand moulded blocks and then compare it with machine compressed block made wall, experienced biilders will know what am talking about.

it is really a misconception from different people, it i not a rule that the so called machine made blocks in Nigeria are better in strength than the manually made blocks.

hollow sancrete block is required to have a strength of about 3.5N/mm2 but most block produced in Nigeria has lower strength of between 0.5 to 1.0N/mm2 due to the practice of not using right mix ratio of say 1:6, mixing sharp sand with plaster sand in other to make molding easy, poor curing etc.

for economic reason while building a house support the building with concrete column, make you block manually since you can regulate the strength considerably.

Have you taken time to read my original post?

I don't think you did because if you did you'll see where I stated my use of specific areas for an engineer.

I never once said I wouldn't employ engineers but I see no use for that level of their involvement on a daily basis even for a complex project.

You don't know my skill set.

I don't need an engineer to hold my hand once they've submitted their deliverables for a project.

We just make things overly complicated in Nigeria for no good reason.

No I won't and I don't buy into Nigerians scare tactics either

Now if you go back and read my post again you'll see that I did write that I'll use engineers when and where necessary.

I just think having an engineer onsite daily during the build is a waste of resources.

To me having them on-site on daily basis may amount to waste of resources when the building is not that complex but when the structure is complex, you need them to supervise the structural work.

people do so many things as regards to buulding and got away with them because of lack of complexity in our structures.
I think the following is very important when planning or building a house.

1. if the building is more than a bungalow, do a soil test. soil test don't cost that much. soil test afford the freedom not to be too conservative in your foundation design because you will be working with the right parameters like bearing capacity, settlement rate, surcharge level, soil classificatioins etc.

2. Do a detail survey of the plot to get the actual dimensions of the plot before you do architectural dessigns. you alsa get to know the relative level of your site through leveling, this allows for drainage control.

3. prepared your architectural drawings

4. Do your structural drawings

5. prepared your servicing drawings ( mechanical and electrical)

6. get a good builder ( he may be an engineer, experience brick layer, architect, building technologies). try to get someone that will be on ground and understand structural details very well, that also understand building work.

7. get a good team of carpenters, mason, iron benders, plumbers and concreters ( man walker)

8. you can now be the chief contractor and also the stock keaper

I am building a bungalow so I was curious as to what you wrote about the floor. In fact this is what I intended to do but I always like to hear others opinions.

please put an oversite concrete ( german floor). imagine spending millions on a house without a dpc that 200k could have done.

you are wrong, people actually need oversite concrete popularly known as German floor.
it performed the following functions
1. help to tie together all the foundation wall
2. help to prevent moisture fromm rising from the soil beneath into the room which most time destroy floor finishes and wall paint
3. it help to create uniform level at the floor which also allow floor rendering to be minimal.

Though, a dpc of 6" with a very good mix may amounts to waste of materials/resources but a dpc of 3" with a week mix of say 1:5: 7 for a bungalow will do wonder.

Regarding professionlas.

OP, the best way to save money is to be your own General Contractor and simply employ "professionals" as sub contractors. This requires work and time on your part but you'll be saving money. This requires you to be on the ground and to come up to speed on the building process. It's not really hard. Just read back in the archives and see first time builder who went into become builders in short time on here.

Good luck.

Honestly that is the best way to save money
in summary
1. get your survey plan by consulting a surveyor/ engineer yourself
2 get the architectural design yourself
3 get somebody to do the bill for you based on your taste and budget don't allow ur mason to give you quotations
4. get a professional engineer/builder pay him based on supervision and always negotiate with ur workers ( mason, carpenter, iron benders etc) based on bill prepared. always start negotiation with a much lower amount than the one specified
5. don't allow suppliers to supply you material, try so many suppliers and get best deal and always be around when materials are delivered to site.

Always be around

Let me give you accurate amount...
firstly foundation should be around..1.300 blocks of 130naira each
Hausa to dig the foundation 30k,
you will pay 3 expert brick layer 2500 naira each to do the setting out,(dont use engineer they are as-hole) just promise those bricklayer you will give them the job,
they should be able to finish the digging in a day
mind you,you will buy peg 2 pack of 2000naira each,then nail 500naira and tie rod,like 50 pieces thats 100naira each
soon as the digging is completed,you will negociate with one bricklayer to collect 100k for foundation will fillings,you will tell him you will dig soak away and he will help you to use it to fill it
then you will pay him 40k upfront,you will buy 2 loads of stone sand for the foundation and 2 loads of normal sand,you will need about 25bags of cement for the foundation floor and another 20 to construct the foundation itself ,soon as the foundation is completed,you will pay 60.000 naira for someone to dig soak away for you,2 bigs one and 2 small ones because its 2 flats,then the bricklayer will use the sand they dig out,to fill the foundation
please dont do german floor at this stage since its bongalow

it is wrong to assume that engineers are " ass-hole".
though u don't need engineers/builder/architects to set out or build your house but never underestimates the power of professionalism.

build a house that can stand the test of time, get a surveyor or an engineer to do your setting out aat reasonable amount.

profile board setting out requires peg spaced at 2m center to center.
material includes
1.pegs
2. 2 x 2" soft wood

pegs required = perimeter of ur building/2m
= 64/2 = 31 pegs

2 x 2 required = 64/3.3 = 20pieces

Please rewrite this in plain English for the students in class

I mean for a bungalow with load bearing partition walls whose wall is supported on a strip footing, column are not necessary. you only introduce column at the junction of the house, where wall span more than four meter without any perpendicular wall etc.

if need arises for column, the column should be limited to the edges of the building.
most cases the column dimension should be 9" x 9" and the pad foundation supporting the column can be 2' × 2'.

Note for a poorer soil with low bearing capacity and settlement rate ( consult a geotechnical lab)
a structural engineer should be consulted to design the foundation and supporting columns. people hardly do structural design for bungalow though.

Thank you for the analysis. I tried to ask the mason how he will do the DPC with 30 bags of cement. He said the dpc will be 4 inch thick and will use 4 trips of 5 ton sand (20 tons) and 2 trips of 5 ton gravel/granite (10 tons). Assuming 30 bags, how many trips of sand and granite will i need for dpc?
For casting of foundation, if 20 bags..how many trips of sand and granite is needed?
For 8 pillars, beams, baskets, lintels, how many trips of sand and granite is needed?
For setting 5500 blocks, how many trips of sand and granite is needed?

Thank you

using mix 1:3:6, for every 1bag of cement, you need 0.17tonnes of sand and 0.48tonnes of gravel.

for 20bags for the foundation:
sand = 20 × 0.17 = 3.4tonnes
gravel = 20 × 0.48 = 9.6tonnes

I'm of the opinion that compromise shouldn't be made here since the foundation is very important structurally.

I'm also of the opinion that a minimum of mix 1:3:6 should be use

you actually need
97bags of cement
15tonnes of sand
46tonnes of gravel

using 30bags of cement will render the concrete very poor in strength.

my advice is to use a thinner dpc of say 75mm (3" wink

40bags of cement
30tonnes of sand
15tonnes of gravel ( since gravel is more expensive and dpc is not that structural relevant )

you don't necessarily need column in a bungalow. you only introduce columns when soil bearing capacity is very poor or when the building is very long.

Hello everyone,
I will need your help in helping to analyse what quantity of materials I will need to build a twins flat of 3 bedrooms of the size in the file below in terms of quantity of blocks, cement, sand, rods (12mm), rings, binding wire, granite I will need to do my foundation about 3-4 coaches, german floor 4 inch thickness, and the superstructure from german floor to level (2 blocks after). The structure will have 15 pillars. what about labor for welder, carpenter, and mason? The site is in Ibadan, soil strong and land, table flat. Thank you for helping with your expertise. I will post a quote I got soon.

Note the following:
you need to placed an expansion joint between the two flat. you can do that by building two wall at the boundary between the two flat an give 50mm allowance.

for a bungalow you don't necessarily need that much columns ( pillars)

=Abdulwastecx: Yes ! I like drawings as well,but you did not include bill of qqs to enable me have a clue of the likely cost implications,pls do dat also without forgetting that I emphasize on minimal cost available without compromising qualities.
Thanks for all of you for ur response and kindness.

To build one of the 2-bedrrom flat, here is the summary of bill of quantity

1. excavation/setting out = 30k
2. strip foundation/ workmanship = 50k
3. sub-structural work of foundation depth of 600mm (3 course ) ,500 blocks @ N220/block including cost of material = 100k
4. DPC using mix 1:3:6 and thickness of 75mm ( 3" wink

plus workmanship = 150k
5. super structure using 15mm block, 3m headroom, 2000 blocks @ N250/block = 500k
6. lintel/ front arc, head course and other concrete work = 120k
7. roof truss/noggin material/workmanship = 250k
8. roofing sheet using long span affordable roofing sheet @ N1100/m2 for 130m2 plus workmanship = 170
9. doors finishes according to taste
10. windows finishes according to taste but will get you a good deal within port Harcourt
11.floor tiles finishes according to taste
12. painting both material and workmanship = N80k
13. ceiling using pvc plus workmanship = 80k
14. plastering inside and outside = N150k

= N1.68 million ( minus windows, doors, floor finishes)
Note:
1. roofing sheet price can be reduce if other cheaper alternative is used
2. roof truss amount can be reduce if gable/flat roof is used instead of the conventional roof

check out the 3 D below, an example a cheap flat roof yet maintaining aesthetic

thanks
