Abdomox:
Hi Sadyfact,

I have 1,500 blocks more to lay to reach lintel level.

What do you think the workmanship should be?

Or how much should laying of blocks cost?

Thank you.

I can know how many blocks would be enough unless i have your proposed design (preferably in AutoCad format).

On workmanship, if you're supervising it directly then pay 55-60 naira per blocks but if you have a supervisor on site (you would pay more)

I'll advice you have a supervisor and pay more - (IN THE END, YOU PAY LESS) if you can decode....

Thank you.

Oga Saydfact, abeg you have contact of anyone that does tank stand in Lagos?, if yes, I will appreciate if you share with me, Thanks in advance.

There is none I can personally stand for.... thanks for following my thread

Happy new month to all our esteemed clients, more finances to your bank account this month and COMPLIMENTS OF THE SEASON.

welldone @saydfact .. i enjoyed every bits of ur posts, more grace to u. but i was hoping u would talk about ceiling and the prices and the best to use for low income earners,

@saydfact compliment of the season.

Please I notice some german floor have some plumbing works been done before the DPC is done, is there a reason for this?

Some you see bare casting alone, does it mean having to break german floor to bury all those sewage and water pipes?

Does all those water pipe been done in conduit in walls away from sight have any implications? I see more modern buildings now without those big pipes hanging over the walls ?

Afternoon and thanks for checking out my post.

In more standard designs where there are a lot of piping (conduit system) - you can run the pipes before german floor OR later by cutting into the german floor (offcourse at extra cost)

But in residential designs (especially the private ones) - designs are done in a way to minimize this, or pipes are run in the ceiling to reduce cost of cutting...


IF CONDUIT HAVE IMPLICATIONS ? YES but that's only if you don't use quality and appropriate pipes plus workmen...If in doubt, you can use both system or lay the 4'' toilets pipe on surface and electrical and water pipes conduit.

Regards

And again oga Saydfact comes to my rescue.

If I read you clearly, a good plumber can study the plan and mark and lay out all the required pipes even before the German floor and all these comes with precision.

I know those wall pipes shouldn't be a challenge to bury in the walls really.

Once again thank you for not getting tired of my questions

YES, a good plumber can do the job with little supervision..... see attached pics showing conduit

the big pipes were buried to create a void and avoid cutting as shown in pics 1...

YOU CAN EITHER LAY THE PIPES OR CREATE A VOID AND LAY THEM AFTER - (as shown in pics 3) where AC Pipe and WHB pipe were paid before casting, yet a void was created (using 4'' pipes) to lay more later on.

Regards

Merci beaucoup for helping to clear the air on this. I would settle for the plumbing layout then before the german floor is cast jeje

@ Saydfact Happy new year baba. Do you by chance have a contact in Arab contractors? I intend buying some fillings from them from the road constructions they are doing along Ikorodu Shagamu express road.

What is the cost of filling sand currently in ikorodu? Do you have a trusted supplier in that axis? I have the very high foundation requiring plenty fillings reason why i dont want to leave anything to chances right now on this project.

Can you also project required materials for the construction of German floor based on the attached drawings please? Are there any flaws noticed in the drawings also please?

Appreciate your selfless efforts as usual.

1. The easiest question to answer is on the design - I must say the Architect did justice to it; maybe the only person who wld have done better is myself ... lol (Just joking) - The design is kk. Dont you want that in AutoCad? It helps to have a soft copy for future references.

2. Filling Sand is 18500 - 19000 in Ikorodu right now - on supplier, I live in Ikorodu so I def shd have someone.

3. If Arab contractors sell fillings legitimately, i'm not aware of and I have no contact there

4. I'll send the projected material for german floor in the next post - I did a lot of free consultation for NL people last year - and still doing it this year, I believe in the end, God pays us all.... but I also do designs (make nna dey give me work ooh)

Which part of Ikorodu is your project?

GoodLuck

buddie:
Can you also project required materials for the construction of German floor based on the attached drawings please??

Estimated Materials:

Granite = 30 tonnes

Sharp Sand = '2 double tippers'

Floor Thickness Used = 100mm (4 inches)

Approx Cement = 75 - 90 bags (75 from experience, while 90 from calculations)

Labour = 65k - 70k (depending on the cost of renting concrete mixer) - I'll advice you use a concrete mixer cos its a BIG floor you doing

1 by 12 wood = 11 pcs BUT sliced into 2 to give 22 pcs (i.e buy 11 pcs of 300 by 3600 {1by12} Somi, slice it into 150 by 3600 {0.5by12} each)
you would need about 3 pcs of 2by4 for the bracing and 3 inches nail of about 1k worth, plus binding wire of about 2k worth.

Carpenter Workmanship = Daily pay (about 3.5k - 5k)

Budget some cash for the people who would do the 'RAMMER', i.e wetting and compacting of the filling.

Water =

I don try....

Goodluck

@Saydfact what can I do without you

You just killed it once again. And thanks for all this free consultation you have been providing to me as a person on this project to this date, God is the only person that can reward you baba.

The project is close to Ogijo area. The cost of the filling sand is scary oh considering the quantity required.

See the funny quote I got, I'm sure he just picked figures from his head cos have been worrying him to send the German floor estimates since 2weeks.

35 loads of filling sand.
30 tonnes of granite.
4 loads of sharp sand.
120 bags of cement.
25 planks of 1*12*12.
5 pounds of 3 inches nail.

What is the cost range for concrete mixer rental and transport in this our area?

Is it not economical to deploy plenty cheaper manpower instead of renting mixer?

See the funny quote I got, I'm sure he just picked figures from his head cos have been worrying him to send the German floor estimates since 2weeks.

THE QUOTE ABOVE IS NOT EXCESSIVE IF THE PERSON WAS BUDGETING FOR A 150mm SLAB - WHICH IS STANDARD; If you look at my estimate, I left the clause that I used 100mm (4inches) - if I used 150mm (6inches) it would run into something close to what you were given.

BUT if you adopt 4inches (which is OK) - see my advise below.

35 loads of filling sand. ---- ONLY SM1 ON SITE CAN VERIFY, YOU CAN BUY IN BITS eg 1st buy 5, then 5, then 5 etc

30 tonnes of granite. ---- YES,

4 loads of sharp sand. ---- I'LL ADVICE YOU BUY 3, WHATEVER IS LEFT WLD BE USED ELSEWHERE

120 bags of cement. ---- THATS MORE THAN YOU WLD USE IF ITS 100mm THICK SLAB BUT IF ITS 150mm THICK SLAB, THEN YOU NEED BETWEEN 115 - 140 (experience - calculation)

25 planks of 1*12*12. - YES, HE'S CORRECT - I ONLY GAVE YOU A MONEY SAVING HINT BY DIVIDING INTO 2 (this can only be done if thickness is 100mm [4inches], if ts 150mm [6inches] then you have to buy 24 planks....)

5 pounds of 3 inches nail. - thats about N250 * 5 = N1,250 so its OK.

What is the cost range for concrete mixer rental and transport in this our area? - 20K OR 25K (includes operator's fee)

Is it not economical to deploy plenty cheaper manpower instead of renting mixer? - MORE EXPENSIVE, AND MIGHT RUN INTO DAY 2.

Good day oga Saydfact,
Having factored the huge cost of this German floor, it has been agreed that we simply fill all the hollow blocks holes with weak concrete of about 4 inch thick and continue straight to the blockwork stage. The room by room filling would be done and cemented.

Hope this cost containment wouldn't have any adverse effects now or in the future?

Lastly, can the 1x12 planks sliced into 2 for this DPC purpose still be useful for the lintel work? Is there a standard height for lintel casting?

Thank you!

Evening... If you slice the wood, you can only use for lintels of areas with 6 inches block.. So don't slice since you're using 9 inches.

On German Floor - you can proceed with your plan... I understand the huge cost associated with German Floor....

Good luck

I. Presume you've NOT seen my post on saving money on lintel? Your workmen won't like it but it wld save you 200k... Search for it here on NL ..... I'm not sharing the link lol

Using same method on this project (pics attached)

Standard height for lintels is 2.1m equivalent of 9 blocks high.

Good luck

Meeee? Is there anything you have written on this properties forum that I haven't read sha? Below is the link to the lintel recommendation. So I can apply this style across the entire openings in the building?


https://www.nairaland.com/4133188/construction-6self-contain-hostel-frm-start

I'm certainly going to recommend this to my bricklayer, casting of all the windows and doors can be done in one day since I have this plenty planks from the improvised German floor and then arrange for the fittings over time, plenty aboki with excess strength full area.. Lolz

My external walls are all in 9inch while all internal wall is in 6inch so the sliced planks still come handy.

HAHAHAHAHAHAHAHAHAHA OK I LOSE THANKS SIR,,

So I can apply this style across the entire openings in the building? DOORS AND WINDOWS ONLY - USE NORMAL CASTING FOR ENTRANCE TERRACE.

I've replied your mail...

Thanks boss. The typical composition for the pre-cast lintel should be the listed if I'm right?

Cement
Granite
Sharp sand
Stone dust (is it required?)
Iron rods (what size?)

saydfact:
Based on the many questions asked the last time out (see: https://www.nairaland.com/3502464/how-build-comfortable-house-earning ) we would go more into details, best working practice, cost implications and questions & answer using the attached plan as our case studies.... i.e we would arrive at an approximate cost of building the house attached.

(We would not be considering government determined processes e.g approval - it is practically impossible to get that info here - visit your local authorities for help)


No1: Preliminaries:
Under Preliminaries we refer to those activities that should be done, considered or made ready before the actual construction process begins. Most times we ignore this process forgetting how important it is. On a couple of occasion, I've visited people's site to help with foundation works only to discover there is a big tree or root where the building is located..

Other times, there is no access to drop materials or there is no provision for water (both for work and for workers to have their bath)

Now what are the important preliminaries we would be considering?

* Clear the bushes, cut the trees & uproot, except trees fall about 3m from building location.
* Buy a small tank for water storage or rent one for the time being (we would safe cash on this later).
* Ensure the tipper delivering materials can get to your site i.e all materials are dropped on your site.
* Ensure you negotiate with the Omo-onile on how much you're expected to pay before the day of foundation - but preferably, don't give them the money until the day of actual foundation works. Most times there is a fraction, and the fraction that didnt get the money would still disturb you. Giving while work is ongoing is perfect because both fraction would have representatives present.

COST IMPLICATION:
* Clearing and uprooting of trees (N5,000-7N,000 would clear your site while N10,000 would clear and uproot all trees)
* Water (find out how much a small tank goes for but it cost about N3,000 to rent & fill a tank of water)
* Workmen usually charge you extra if the material is not dropped on your site, because they also have to pay workers to move the material to the site. This sometimes is a lot we're talking about.
* Omo-onile could charge as much as N50k to 100k depending on your location.

>> Labour Cost: 10k

SUMMARY: The cost in this section are dependent on so many factors; its almost impossible to put a figure to it; my advice would be to safe about N100k for this section; most of that being fees paid to Omo-onile.


No2: Works Below Ground
Works in this sections include (but not limited to)
a. Setting Out
b. Digging
c. Foundation
d. Block-works to foundation
e. Filling
f. German floor

A. Setting Out: The bricklayers claim we waste money by using profiles (setting out using wood and ropes) but they often create problems with their method of setting out using blocks. Since this thread is not about anybody but professional practices, we'll consider setting out with profiles.

Materials Needed: (Based on the attached design)
1x12 plank = 4pcs, each sliced into 4 each.
Pegs = 32 pcs approx 3 dozen
Nails = 2" and 3" - buy about N1000 worth
Ropes = 4 bundles each at about N200

Workmen Needed:
One carpenter or anyone that can handle the hammer = Daily pay
One experienced Supervisor = If its an experienced bricklayer Zero Naira except he's not also doing the actual work, if you're getting a supervisor for this price would be around N10k.
The diggers or at least one of them = Cost wld be analyzed below.


COST IMPLICATION:
* Planks: 4 x 1200 = 4800
Cost of Slicing per line = N70 x 3lines = N210 x 4planks = N840
* Pegs: 3 dozens x 1200 = 3600
* Nails = N1000
* Ropes = N1000

>> Labour Cost - 12.5K

With a total of about N11,500 (material cost) - paying this amount to ensure your house is properly set out isn't bad investment - if your bricklayer is experienced thats good, you can however get someone to set it out for you for additional N5-N10K depending on your relationship with him or her. (Personally I do this most time for free if I designed the structure to ensure some in-experienced guys don't spoil/change my hard worked design)

B. Digging: The books recommend about 900mm depth for foundation but practically, its almost impossible to achieve this on very solid soil we're considering. If you can get your workers to achieve 450mm - 600mm depth great and a width of 675mm

If your plan like mine is to do a German floor, there is no need to dig out some wall partition - but if you have a plan to continue without German floor, then all wall partition should be dug (although I don't advice my clients to use the second method; I must be realistic that it comes with an initial cost most are not willing to spend)

ADVICE: I still recommend using experienced guys, people who are used to digging foundation (don't get the Hausa guy that cleared your site to dig because he did a good clearing work, or the Ibo / Yoruba guy because he claims he's done it before). The advantages are those doing this work are:
- Quicker
- They dig straight and ensure a level surface (makes it easy for the bricklayer)
- Saves time and material
- They charge appropriately.

The attached structure would cost you about 30K to dig; with six (6) quality hands digging, you should have it completed in a day or early hours of day 2; still in time for the foundation (concrete pouring) works.

COST IMPLICATION:
* Digging = N30,000 - N35,000
* Water for workmen = N1,000 (about 5 bags of pure water).

>> Labour cost - N35k

Note: We would give individual cost, but after each section add up to help your bargaining power - it means if all works sum up to say 30 naira, you can give all works out to the bricklayer at 25 naira - you're only asking for discount for giving him so much at once. #wink

C. Foundation: This is the first of many important works and where most people unnecessary save material and money; infact most bricklayers would even help you save here NOT BECAUSE THEY CARE but because it means less work for them at the same price of the actual work.

Normally the standard foundation thickness should be at about 150 - 175mm for bungalows (remember we're building on solid soil) yet you find some people using as little as 50mm - 75mm ie 2" - 3" - You end up using about 15 bags of cement, then claim the professional wanted to cheat you by recommending 35 bags - NO; the professionals' calculation was based on a standard 150mm thick foundation, what you did was 50mm or 75mm. Lets hope your house can withstand the weight to come.

MY ADVICE: Ensure your bricklayer starts from one corner and transfer levels across to the others - to ensure a level plain for the block works, if the foundation was dug well leveled, this should be a easy process. Every good bricklayer knows the importance of having a level plain; cheap labour is most times bad for the job. avoid picking your workmen based on cost only, especially if you're doing it yourself.

Materials Needed:
Volume of Concrete = 101.55m x 0.675m x 0.10m = 6.85m3 (based on attached design)
Cement (approx) = 27 - 30 bags
Sand: 20 tonnes (this should serve for all works minus German floor)
Granite: 30 tonnes (recommended) or 15 tonnes (being the minimum you should purchase)

* If you cant afford Granite, then buy Double tipper of gravel, however ask your supplier to ensure it doesn't have too much of sand, you could add the phrase "I'll reject it if sand is too much" - makes the supplier more alert to ensuring you get the best possible. Don't expect a miracle, gravel are mined with sand.


COST IMPLICATION:
Material Cost:
Granite (15 tonnes) = 60k - 65k
Granite (30 tonnes) = about 110k - 125k
Gravel (Double tipper) = 35k to Ikorodu;
Sharp sand (Double tipper) = 30k in Ikorodu; 55k to Mowe/Ibafo
Cement = N2,350 / bag (including transportation)

>> Labour cost - 25k

Note: Depending on your negotiation with your bricklayer, you might have to pay for renting of tools eg shovels, wheelbarrow etc, however, this shouldn't cost too much its about N100-N200 per day for most tools.

D. Block-works to Foundation: My recommendation here is even when you intend to build with 150mm (6" blocks, ensure you use quality 225mm (9" blocks for the foundation. We can't guarantee the strongest 6" is what you've brought so; spend a little more and safe your building. (I am aware that Ghanaian however build with 6" - solid block even in storey building)

Materials Needed:
9" Block @ 4 courses = 910 pcs (including waste). 9" cost btw N150 - N180 while 6" cost about N160 each, depending on quality and location.
Cement = 15 bags should do the job (Most times, there is a few left over from the foundation - so you'll only buy the balance) - Don't forget all calculation considers waste, so the less you waste, they more you save.

Sand? No, we've got enough

>> Labour cost - 50k

Since I recommended in my previous article that we negotiate all works above at once, lets see how much labour cost we have:
Setting out = 10k
Digging = 35k
Foundation = 25k
Block setting = 50k (see previous post if you need a hint on how we arrived at 50k)

Total: 122.5k we didn't add the 10k for site clearing (Now, how well can you negotiate?) - Put that to good use.

E. Filling: I actually don't advice anyone buys filling solely for this purpose, you would dig your septic tank / soak away one day, where would you put the filling? Probably pay to get it out of your site or sell at very cheap price. SO! DIG YOUR SEPTIC TANK and use the discarded filling for this purpose.

If you don't get enough filling to level your site, you'll only need to buy a few more trucks. see No3 below for detail of material and cost implication on septic tank.

Note: If you're using this option, then ensure you have enough cash to complete the septic tank/soak away 90% - 10% being the slab cover.

F. German floor: I recommend you do this, but I most also note that it comes with some cost implication. We'll analyze the cost below, then you can weigh your pocket.

Total Floor Area: 113.63m2
Volume of Concrete: 11.34m3

We'll try and generate a rate per m3 in-case you have a different design and volume.....hmmm, that rate would be N2500. (pls note that this rate does not work for decking and doesn't work if you're using machine)

Keep 5K at hand, the omo oniles' no dey take eye see concrete...

COST IMPLICATION:
Materials Needed:
Cement: 35 - 40 bags (4" thick)
Sand: 20 tonnes
Granite: 15 tonnes (but if you brought 30 tonnes initially, you're covered)

>> Labour Cost: 30K

No3: Septic Tank & Soak Away

Lets pick a size; but depending on your site that site might vary. In the previous article, my cousin had very little setback (remember I told you the site is less than half plots (18x18) - so, we picked a narrow width and a very long length to compensate.

Let's use Septic-Tank size of 2.4m width 3.0m length x 3.0m depth and Soak-Away 1.8m x 1.8m x 1.8m

COST IMPLICATION:
Materials Needed:
Septic Tank = 280 (9" blocks) & Soak away = 110 (6" blocks)
Cement = 8 bags (including concrete footing for septic tank and plastering of the inside)
Note: only septic tank has a concrete base, as the name implies soak-away is left natural so the water can be soaked into the underworld. #wink

>> Labour Cost:
* Bricklayer = 33.5k (all inclusive plus plastering) Normally I'll pay less, the bricklayer has justed finished foundation works and he's assured of the super-structure, this is where I tell him, look - you have a lot to do together, I can only pay 25k for all works....
* Digging only = 20k-25k


GENERAL SUMMARY: (Using the highest options i.e If cost above says 30k-50k; we'll be using 50k for this section)

TOTAL MATERIAL COST: N721,590
TOTAL LABOUR COST: N331,000

I EXPECT YOU WOULD SPEND LESS, BECAUSE WE USED THE WORST CASE SCENARIO.
