Where is the starter bar for the stair?

see attached pics.... (I have to be ready for your questions now sir.... lol) - thanks for following.

Rubbiish:

This is how far @ Dembuk2009 's project has come.


MORE PICS (During and After Casting)

cc: Rubbiish, asids55,

The project so far...... There's been a change in plan, from that bungalow to a storey tall.

Stage of works so far.

German Floor.... and filling the compound to a level to prevent rain water staying on site.

HI, (My reply in bold)

megacontrol:
Hello man, i want to start sand filling a land in preparation for building soon and will like to ask;
1. how much of the top soil (depth) has to be excavated before sand filling to avoid soil movements in future
Not much, just ensure you remove all the bad soil i.e soil that has green growing on it, debris and rubbish dumped on the site, wood and all material that can decay, plastic etc - if you're not sure just remove about 100cm of top.

2. how long should the sand fill be left before the foundation commences
About a year is perfect but if you don't have that much time, fill about 450mm high and compact mechanically (rammer) until you reach the required height ie (wet and rammer in layers)

3. any other tips to achieve solid foundation
Get qualified men on the job, ensure adequate rebar spacing, use appropriate rebar (iron) and seek professional advice etc

recommended foundation type - raft
location - swampy/waterlogged
planned build - duplex (ground & first floors)

thanks

GoodLuck

LFC Isn't relying on him alone onlike when we had Suarez..

And I thought you all said Coutinho was the messiah.

That goes to proof LFC is a complete system working so well.

Firmino has over 24goals already and Mane 14..

Please read up on PUNCH Through. Foundation Engineering requires Matting to spread both Live Load and Dead load that will result from your German Floor, deck , roof etc.

I had to take a long walk to get network to type this reply I'm on a site in a poor network zone.

Let me say this.. He's NOT an engineer for 2 reasons.

1. No Engr wld use pad foundation ie mat on waterlogged soil

2. Mat and pad foundation is for this type of soil.

Can sm1 help with pics to guide our man here..

It's better to correct it now... Or u might spend millions later.

This reply is for asids55

akpamfet:
FTC?

wake up - you're dreaming

asids55:
how can I reach out to you,I sent you an email but no response

Sorry I was sympathizing with Chelsea Fans.. Thanks for the call..

mufutau55:
Can you explain further on this? What kind of maintenance does parapet requires? Thanks.

Hajji M.

Parapets are walls above roof (i'm not referring to concrete facial which are popularly referred to as parapet but technically aren't)

On the maintenance i was referring to = WATERPROOFING (FELTING SYSTEM), FLASHING AND CAPPING - in simple terms the point where the roof materials meet the block walls etc.. see pics attached.

asids55:
what kind of cost can one run into in the long run?

let me put it in simple words = parapet roof are more expensive to maintain

asids55:
hello house,what do you guys think of having two stair cases in a duplex built on half plot of land,and pls which roofing style is better

I'll go with the first (black - Hip) roof - less maintenance cost on the long run........

2 staircases ? - well, what we have are standards or minimum requirements - the minimum requirement is obviously 1 stairs but by choice and for other reasons (including security, functionality, choice) you can have 2, 3, or 4.....

GoodLuck

WHAT ABOUT LOOTERS? by Nuclear Bomb i believe

Except the definition of SME in Nigeria = Average Billionaire's business

wasted fund

adeyanwale5:
saydfact, what about the numbers of the reinforcement needed for lintel of our 3 bedroom?

Pls check the links I sent to you. I have answered all questions on the plan there except painting.

Thanks

Hi, saydfact.
I have a sketch for a generator house, can you kindly look at it and give the required quantities of blocks, cement and all required to complete it? You can reach me on WhatsApp at 07036383449 and by email at lexezra@gmail.com. I've sent you mail to your advertised in mail and also a p.m here on the forum.

I hope to speak with you soon on certain other projects that will require your expertise. Its for a 2bedroom bungalow.

Thanks a lot.

Foundation = 4.5 bags of cement
Columns = 3 bags of cement
175mm thick German floor = 14 bags of cement
150mm thick concrete roofing = 10 bags of cement
150mm or 225mm Blocks = 370 pcs
(L x B) Screen block = 14.76m2 / (L x B) = pcs of screen block needed i.e when you decide on the screen block to use, multiple its LxB and apply in the formula above eg if its 150mm x 150mm then = 14.76 / (0.15x0.15) = 14.76 / 0.0225 = 656 pcs. (for both screen wall and screen windows)

Granite, Sand, Plaster sand etc are minimal - Buy the least you can afford eg 10 tonnes of each.

Reinforcement Bars = Use 12mm all round.... or 16mm in columns if you can afford to...

Goodluck.
Good luck.....

can you get the size of the perforated blocks you intend to use? L x B x thickness (optional) eg standard block is 225 x 450 x (150 or 225 thick)

I sent you my Whatsapp nos by mail.

spyder880:
1. What's the likely cost of fitting a small elevator (say 1.2 metres sq) in a house with 5 floors in Nigeria?

2. Which are the leading companies in elevator installation and maintenance in Nigeria?

I just want to understand why the use of elevators is not widespread in the country.

constant electricity is a major reason.

if you cant keep the gen on for 24hrs, you don't consider using a lift - that is an outrageous cost in a public residential / low cost apartment.

abdulwastecx - the dimension you gave above on the 3 bedroom for adeyanwale5 wld NOT work for them, I know this because its a design I did..

except you have plans to modify it....... also the drawings are in meters/milimeters not feet....


cc: Rubbiish

adeyanwale5:
this is the plan and measurement of my propose building

pls i want to know the total number of blocks, cements, sand and gravel required


strip foundation is what i have chosen

pls i really need the estimate.

THANKS

@adeyanwale5

why ask EgunMogaji for the quote when this was a free design I did for people on NL - offcourse you're free to use it, but respect my works enough to ask me for more details if u need it.... most NL wld confirm i've offered such services for free.

BTW: You dont need an estimate, just read the post where you got the design from, i broke down major cost there.

@Rubbiish, thanks man - you're a great guy..

bomsilaga:
the model of the raft you showed and the raft you posted in practice are they the same?

YES

4gunners:
The depth of the excavation for pad foundation will be determined by the structural engineer designing the foundation. The depth depends on so many factors such as the bearing capacity of the soil, size of the column, load the column is carrying etc.

I guess this is a more technical answer... Thanks

calculation:
Please, I need to ask question concerning pad foundation. In pad foundation how do we determine the depth of excavation from natural ground level?
Is it when the excavation get to hard soil level or there is factor that determine it. Thanks for your write up as it really help me to understand some stuff on building and design.

Pad foundations are used on hard soil... (remember I said stabilization is needed if the soil is soft, at the end of stabilization, the soil becomes hard)

Depth of pad foundation is usually between 900mm - 1500mm

What matters most is the size of the pad I.e. Length and Breath and the reinforcement in it.

Thanks

@EgunMogaji and Calculation

Thanks for the note....

calculation:
OP, Pls attend to the quote statement of EgunMogaji. paragraph is bolded below

Recommendation: If you're building a warehouse, workshop or structures that have limited of no wall partition, then this is the foundation to use - It can be used on strong and weak soil. One weak soil, the soil has to be stabilized and left to settle / rammed mechanically before the pad can be used. The size of the pad foundation and columns are determined by

One weak soil, the soil has to be stabilized and left to settle / rammed mechanically before the pad can be used. The size of the pad foundation and columns are determined by THE LOAD TO BE TRANSMITTED AND TYPE OF SOIL, YOUR STRUCTURAL ENGINEER IS THE BEST PERSON TO ADVICE ON THIS.
