Sir Triangular style u meant @bold?

It was triangular HR had initially written

mufutau55:


Go for the regular squared iron lintel with Y12, you won't save much on the iron with triangular style..

Hajji M.

Rubbiish:

U can use 10mm for the Red, blue, black & green colours as suggested by one of the professionals here to save cost. & use 12mm for only the four reinforcement at the block level for d parapet.

On the average, please have you got any idea of the length of why blue colour iron rod is.

Sorry for my questions o

Thank you so much.

Rubbiish:

Rubbiish:

All colours are 12mm for concrete fascia

Rubbiish:

Your rod sizes and arrangements are ok for d lintel. But try to do square instead of triangle if u can. People do triangle, but i don't think it is standard practice.

Thanks so much bro. I appreciate your feedback.
God bless.

Hi All,
Please anyone to assist with the sizes of iron in the picture below as it relates to the arrow colours. Also what is correct spacing between them.

I want to do a rough estimate of what I may likely require for concrete parapet.

Many thanks.

Hello People,
Please assist with the sizes of iron rods as per the attached as it relates to their colours.

I appreciate.

mufutau55:


For me personally, the savings does not justify it. Simple.

Hajji M.

Boss,
Please what's your advise and what do I do.

Hi Good People,
Please for a bungalow, does using a triangle lintel iron have any effect on the building?

the rings will be 8mm while the internal rods will be 12mm with a 10inches spacing.

Hi Oga Segzy,

Please for a bungalow, does using a triangle lintel iron have any effect on the building?

Hi Good People,

How do you sell per sqm

There is no difference in quality with respect to Gerard brand of roof tiles. Preference for a particular Gerard design is a fall out of individual choices. Moreover just that the Classic and Heritage (Bond) designs happens to be cheaper than other designs hence the preference but they are all same quality with 50years manufacturer warranty from AHI roofing of New Zealand that produces Gerard.

Thanks for the clarification.

Please can we have this prices of these Gerrards and Accecories

Boss,
Please could you assist with concrete parapet quotation for a 19.8m by 13.0m Building.

Assist with your contact details for WhatsApp .

Will really appreciate it.

Casting done

Boss,
Could you assist with details or materials used for this particular job or better still, is it possible you give materials for a parapet of a building that is 19.8m by 13m in terms of
1. Iron rods
2. Planks and wood related
3. Cement and other materials.

Will really appreciate it.
Thanks

Please does classic or bond Gerard roofing sheets have any advantage over the other types of design. I have noticed that, people mostly use the classic design.
Please educate us

segzy14:


I have sent this information to you via WhatsApp before now.

Boss,
I have been chatting with you on WhatsApp but no response

Dear Good people,

Please assist with materials for concrete parapet that is moderate for a building dimension of 19.8m by 13m

I would also appreciate if you can give the number of parapet curves in a 1 by 12 plank.

Thank you as I await feedback.

Many thanks for the feedback.

i am actually banking on wealth of experience and knowledge to assist on this below.

kindly assist with what you know based on your experience.

1. find out the area of plywood purchased ie L x B of plywood
2. find out the area of 1 curve to be gotten; note: its L x B meaning there wld be waste - most parapets wld be 450mm by 450mm
3. find out how many curves you would get from 1 plywood
4. The total number of curves you need for that parapet perimeter is = 109 numbers (@600mm c/c)
5. Find out how many plywoods would give you the required number.

i actually dont want to do pre-cast parapet as those i have seen for me is not encouraging.

saydfact:


Thanks for the compliments; well appreciated.

To your question on the parapet curve; the principle is:

1. find out the area of plywood purchased ie L x B of plywood
2. find out the area of 1 curve to be gotten; note: its L x B meaning there wld be waste - most parapets wld be 450mm by 450mm
3. find out how many curves you would get from 1 plywood
4. The total number of curves you need for that parapet perimeter is = 109 numbers (@600mm c/c)
5. Find out how many plywoods would give you the required number.


1by12 somi/white wood = You'll need about 50 numbers sliced accordingly.

You should need some 2x2 planks and Bamboo to support too -

The above does not include all the plants you need for scaffold ie for workers to stand on etc.


I prefer using precast parapets or polystyrene parapets majorly. (more affordable and lighter in weight)

curved type of parapet.

or better still could you assist based on your experience with the planks and iron rods to be used for a curved concrete for a building of a dimension of 19.8m by 13.0m

segzy14:



What type of parapet do you want to do?
Step, curve type?

Dr. Segzy,
Please how many parapet planks can be found in 1 by 12 plank

Baba,

You are Simply the best

Please can you do a rough estimate of number of planks that will be required for a concrete parapet of building with an external dimension of 19.8m x 13.0m.

Please how many parapet curves can be gotten from a 1 by 12 plank.

Thank you

saydfact:


CONCRETE = Cement + Fine Aggregate + Coarse Aggregate

Fine Aggregate = Sharp Sand or Stone dust

Coarse Aggregate = Granite, Gravel

As long as you have all 3 in the right combination; you're good to go.

Note: There are some very clean gravel (without sand content) s good as granite but it's scarce in Nigeria hence I'll advise you use Granite.

Chief Saydfact,
Please i want to inquire which combination is best for concrete making.

Cement ➕ Granite

Cement ➕ granite ➕ sharp sand

Cement ➕ granite ➕ gravel

Help rate in terms of strength

saydfact:


That's why I said the workmanship is class - I wont have done better under same circumstances.......

180k from foundation to lintel is a good deal - how where you able to achieve that?

Thanks Boss.

I had agreed this fee with the head labour before we commenced at all. I have paid 80k to this level and 100k is the balance to take the above foundation block setting.

segzy14:
@muyi002, 150mm to 1foot is too much for blinding that was why it consumed too much cement.
Labour for laterite filling is much,4K per trip is fine.4k x11=44k not 70k
By the way, did you engage an engineer or it was DIY?

Dear Segzy,
I honestly like you for what you are doing on this forum and topic.

I had engaged an engineer who advised at least 6 inches high is good for the blinding for a trench depth of 2feet (600mm).

As per the laterite, in terms of trip for you how many tonnes will be a trip as mine is 5 tonnes per trip and what i used was a big truck (Mack) which took 25 tonnes at a go.

However, does this have any adverse effect on building (i mean the blinding at that height)?

saydfact:


Afternoon and thanks for checking back..

Estimate looks OK and workmanship is class....

keep it up...

Thank you.

What would you say of the structure of work done. also the cost of labour is N180,000.00 which comprises of setting blocks to lintel plus cost of digging and blinding.

in addition

Hi Saydfact,
See below of what I have spent so far up to completion of foundation. I hope expenses is in order.

@muyi002
1. What is the thickness of your blinding?
2. Were all the materials purchased for blinding used or there were leftovers?
3. What is the size of your soakaway?
4. How many trips of laterite did you buy and what is the size of the tipper?
5. I suspect a foul play in the cement usage.
(88bags to this level?)
6. Labour is cheaper in your location, why did you spend more on this?
7. I cannot see the wire mesh and the Labour for the blinding

Many thanks Segzy,
See below answers
1. What is the thickness of your blinding? This varies due land topography. The thickness of the blinding is between 6 to 12 inches
2. Were all the materials purchased for blinding used or there were leftovers? As at now I have leftovers of granite, close to 6 tonnes and sharp sand of about 4 tonnes
3. What is the size of your soakaway? Size is 12ft by 8ft by 8ft deep - see pic attached
4. How many trips of laterite did you buy and what is the size of the tipper? 10 Mack's of 25 tonnes of laterite @ 28k each plus additional 15 tonnes
5. I suspect a foul play in the cement usage.
(88bags to this level?) I monitored the use of 30 bags for blinding and no Stealing, I partially monitors cement use at setting blocks for foundation but lost count of 6 bags at a point cement for half DPC was also monitored with no stealing.
6. Labour is cheaper in your location, why did you spend more on this? I don't understand how mean by spending more. Where was money more spent, kindly explain
7. I cannot see the wire mesh and the Labour for the blinding. The wire mesh was used for the half DPC and it's embedded. The total labour cost agreed was 180k and this covered digging, blinding and block setting to lintel level and for this purpose 80k has been paid

I Miss currently building a 4 bedroom apartment and total charges for labour is agreed at 180k but he his charging me separate for laying blocks for Soakaway (12ft by 8ft by 7ft deep) pit at 20k and filling of the foundation at 15k.
Please see image and advice.

suraaj:
I strongly believe it very high, am presently building my own,digging of foundation, blinding, laying of blocks for foundation and setting of blocks to linted level with 2500 blocks, we already used 1900 blocks to linted level, remaining 600 blocks,he charged me 180k for workmanship from foundation to level and it is 3 bedrooms bungalow all ensuite with 2 sitting rooms, to linted they spent 21 days.

Hi,
Please does this 180k includes setting of block for the soak away pit and filling of the foundation ➕ charges of lintel and pillars or it is STRICTLY for building block laying only

Amastermovic:


A bag of cement to lay 50numbers of 9inches block

for a column of 225by225 each use....

cement 16 bags
gravel 35 wheel barrow
sharp sand 17.5 wheel barrow

I estimated using wheel barrow to measure the materials needed incase u still have materials available at ur site because in tonnes its small..

though I don't know what stage of work u r presently if you r just starting adding d footing German floor etc to the estimation will increase it... if you already built and only want to insert d columns estimating the materials will give a better view of the materials like 5tonnes which can easily be got.. I hope you understand this... and my bozz koolengrtimmy will finish d rest for u via whatsapp..

Thanks a bunch to the two of you
