THANKS BOSS.... Appreciate

You’re an elder

not really - just early interest

n3xt:
You don’t mean it. Most of the CAD generation don’t even know what it is.

It seems you’re in the line.

Perspective and Elevation Drawings just came to mind now. Before 3D, there’s freehand perspective drawing

My 1st 3ds using the projection method was in 97/98...... the method stock like 1+1

n3xt:
Yep for light. What about ventilation?

How about eliminating the walls in the blue area to throw in light and ventilation into the area? That’s is turn the private lounge into a dining and extending the kitchen towards the red area.
A small terrace can also be introduced in the laundry area to throw in natural light and air into the building.

You can never take away the importance of natural lighting in a 21st century house.

Dear,,,,

I must commend you -

In Architect, EVEN IF and i repeat EVEN IF the president of NIA designs a flat (as small as that is) - a year 2 student of Architect would fault it and be justified..... THERE IS NO 1 SOLUTION; just a client brief and a design that best suits that....

However, your comments are constructive because you have attempted to solve any client concern that arises....

WHY WOULD YOU THROW AWAY SOMEONE'S STRESS BECAUSE OF COMMENTS FROM ANOTHER? I'M SURE YOU AGREE THE INITAIL ARCHITECT HAS INVESTED TIME AND MONEY TO GET YOU THAT....

IF YOU WANT ANOTHER DESIGN, TAKE ALL THE CONSTRUCTIVE COMMENTS TO HIM AND HE WOULD DO A GREAT JOB..

I'LL SAY THIS - THE GUY WHO CAME UP WITH THAT DESIGN KNOWS HIS ONIONS.......... but it's your decision anyway not mine... I can only advice

flekky07:
Good day every1 i hope we all had a lovely day? Since i hv posted this i can not find response to it, only from Chekitaut requesting volume required.

I also read he did something to a popular builder in the forum, where are all the suppliers in the forum or his he the only one here?

Brabus, Rotech77, Great Hajji, Egunmojaji(my baba oko) segcymore, Aventure, saydfact, diordaves, abdulwastecx, mrsteel etc. We are not seeing any recommendations, only 1 person talking on building materials.

Jesusson2020 pls send me a mail let communicate or give me your number via mail.

Dear Flakky - I'm not a supplier... sorry I didn't say that earier.
Thanks

Ibk2020:
Good day,
Please advise needed for this floor plan, I am planning building soon, so the architect sent me the floor plan.
I didn't asked him to include private lounge, so I will ask him to remove that, also please let me know if the room size and main living room size is standard enough. I want the master bedroom toilet to accommodate a jacuzzi.
The land is 450sqm

THANKS Abolarin91 for tagging me....

IBK - I'm a conservationist Architect (whatever that means ) but I mean is I DON'T BELIEVE IN WASTING SPACE OR MONEY (this is different from compromising quality thou)

My Verdict: THERE IS ABSOLUTELY NOTHING WRONG WITH THE DESIGN OR IT'S FUNCTIONALITY - my only concern is

1. You'll need to use a lot of land space
2. Would be more costly for many obvious reason

IF THE ABOVE ISN'T A CONCERN - Then he shd remove the private lounge (you didn't ask for) and BINGO.

Congrats and Goodluck

HI ALL..

Is anyone starting a foundation soon on a sandfill, waterlogged soil (that requires RAFT foundation).

Mayor78:
SayDFact has helped with how to estimate perimeter wall. Go to the thread and acquaint yourself with the measurement of blocks and calculations to estimate your own walls, and thank him for his efforts thereafter.

Thanks Mayor - appreciate;

@Rerin - oya pick ur calculator and you're good to go

Fromwater:
Money don finish be dat.
Well my priority doors are main entrance door (iron), exit door (iron) and the masters bedroom door(wood).other doors can wait.
So any review?

Its OK -
BUT complete the windows and burglary

God's strength

Rerin:
Kindly assist with this request. how many blocks to use for four units of two bedroom flats with 43ft long and 35.5ft breadth, number of cements, bricklayer construction fee, no of tons of sand, please only to construct. Is it advisable to use ordinary sharp sand without using the yellow sharp sand

Na plan fit do am oooh

kopell:
Hahaha no problem. I can tell you am one of the first 2,000 people on this platform with different name then. No need for all these Lang stories. Have nice day.

no prob ..... na play we dey play..
appreciate

mufutau55:
Thank you. Real difference. Next time I must use the 8cm. Please may be you can tell us about the mix ratio too.

Hajji M.

6cm is for walkway while 8cm is for drive way.....

kopell:
you don’t have respond or apply if is not okay with you. I know what am talking about okay, if we tell the story of some of these guys behind the screen you be suppressed. So if you don’t know please stay away, no one is playing God here.

Ironically - I've been here b4 you - so it's me who's telling the story...


I LIKE YOUR REPLY THOU - YOU WERE ANGERED BUT DON'T LET THAT MAKE YOU PASS AGGRESSION ...... OYA, i change my mind - I wan apply

kopell:
thanks. I want to hear from all those sand and granite supplier making those noise about size of trucks quantities of materials. This is opportunity to proof yourself to supply 8 or more trailer if you all mean business. Post your prices here like I said before, with your reference of previous supplies without any drama attached. I will get in touch with you. Location Ajah.

Sir....

The fact you're giving out a job dont mean you shd sound like god..

1. all those sand and granite supplier
2. making NOISE about trucks quantities of materials
3. opportunity to proof yourself .. if you mean business
4 without any drama attached

LOL no way I'm applying if I was one

Fromwater:
10 windows
8 doors

You'll need to spend about 400k to fix all doors, windows and bulgary (on low budget)... security is keyy.

You have 600k to plaster the living, dining, kitchen and 1 bedroom

there would be a little left to tile the living room at least.

Goodluck

Fromwater:
People are living there already and some structures are being raised there too.
Will the 1m be enough to fix just the masters bdrm, living room, dining and the veranda, excluding the other 2 rooms?

YES

How many doors and windows are there in total ? thats the major cost

[quote author=Fromwater post=93670470][/quote]1st question is; are there people living around there already - maybe the way you took the pics made it look so

2ndly - 1m wont do much, I wld have advice you pay 1 year rent and do everything to raise about 2m to get it habitable in 365 days.

Goodluck

Fromwater:
Good morning everyone.
I've been following this thread for a while now and it has been helpful.
I need advice on what to do in this situation.
My landlord has increased my house rent and I have a 3bdrm bungalow at hand which I have roofed.
Now I have 1 million naira at hand. I want to ask the experienced ones here, is there a way to manage this money do I can move into the house. Thanks

share a picture of the house in question...
Goodluck

Mayor78:
Very well detailed. Rogue contractors may not like your effort, but keep it up. Real people will appreciate you.

THANKS BOSS - who go make am go make am, no be by duping

Hargbo:
Well done sir

Thanks

rajput4real93:
Thanks for your selflessness. May the lord bless your efforts

Amen boss.. Appreciate

Johntemmy:
@saydfact I wish you good luck bro..

Amen Boss....

Teewhy2:
very detailed, this should help a lot of house owners during estimation. want to ask can't the bamboo be placed at 600 x 750mm C-C or 750 x 750 mm, will it have a negative effect on the bending moment of the slab.

The challenge of increasing beyond 600mm is the quality of work done - at 600mm you're assured if any bamboo isn't well placed, the 2 beside it can cover for it - going beyond that might be a risk.

saydfact:
UPDATE:
10 likes is enough to do this....

So, I edited the Plan I once shared on NL - to include a staircase; This (attached) is what we'll use for the tutorial... (on a different thread; link soon)

wish me Goodluck -

THANKS TO EVERYONE WHO LIKED MY POST TO DO THIS - IT TOOK ALMOST A YEAR BECAUSE I ABANDONED IT; BUT GOT THE ZEAL TO SEE IT THROUGH FROM HERE.

How To Practically Calculate The Quantity (m2) Of Roofing Sheet Required >> https://www.nairaland.com/4778694/how-practically-calculate-quantity-m2

Good day all,

So, I got a few 'likes' in the property sections to do this; designed for site supervisors, carpenters and welder/iron benders, contractors and DIY aspiring home owners. A lot of people have lost job opportunity because they 'over quoted' and others have fallen victim to under-quoting resulting in them running-away or abandoning the projects.

We would practically calculate all the materials need for the below 3 bedroom apartment (plan attached) - at the end of this tutorial, I expect that your estimation of beams and slab (decking) should be better or closer to reality.

Let's get to business - attached below is the slab (S1,S2,S3, etc) and beam (1,2,3, etc) design.

www.nairaland.com/attachments/12273401_nltutorialsmodel001_png5195f931dfd586ad0972d2352ff6e271

Let’s get to business; below is a list of items we would be calculating.
1. Bamboo
2. 2by3 wood
3. 1x12 plank
4. 8/10mm rings in Beam
5. 16mm bars in Beam
6. 12mm bars in slab
7. Granite, Sand and Cement in beam & slab
8. Estimates for others (binding wires, nails etc)

To get a more accurate result, I have divided the slab into sections (S1, S2, S3 etc) - it is possible to take all the slabs as 1 unit for more experienced persons. (the method we would use is give detailed calculation for 2 or 3 sections and state the answer for other (to safe thread space).

NOTE: All dimensions are in Millimetre *

1. BAMBO
Bamboo are placed at 600mm c/c (center-to-center), and are placed in orderly manner vertically and horizontally - hence all we need calculate is number along the X axis and along the Y axis and multiple for numbers. . . . lets go practical now.

SLAB S1 = 1350 by 3300.
Number of Bamboo along any axis = (Distance / 600) + 1
hence: (1350 / 600 ) + 1 = 3 and (3300 / 600) + 1 = 6
number of Bamboos needed for Slab S1 = 3 X 6 = 18 nos

SLAB S2 = 3300 by 3300.
>> (3300 / 600 ) +1 and (3300 / 600) + 1
>> 6 x 6 = 36 nos

SLAB S3 = 2400 by 3300.
>> (2400 / 600 )+1 and (3300 / 600)+1
>> 5 x 6 = 30 nos

Now; calculate for SLAB S4 to S12
S4 = 21 nos; S5 = 36 nos; S6 = 18 nos; S7 = 48 nos; S8 = 15 nos; S9 = 9 nos; S10 = 56 nos; S11 = 21 nos and S12 = 36 nos

Total nos = 344 nos (BUT this is not the total number of Bamboo to buy EXCEPT you're buying used bamboos)

Because New bamboos come in about 10m up; divide the answer by 2 = 344 / 2 = 172 pieces (the off-cuts would take care of minor bracing)

Bamboo for temporal (mallam) staircase used for casting = approx number = 10 pieces.

TOTAL BAMBOO TO BUY = 172 + 10 = 185 PIECES (Approx to nearest /5)


2. 2by3 WOOD
2x3 woods are placed directly on the bamboo and under the 1by12 planks, to transmit the load across and hold all the plank in place. It is also placed at 600mm c/c and has almost same method of calculation as the bamboo. (for ease, we would also calculate it in sections)

Lets calculate the quantity of 2x3 needed for S1 (pick any side to align the wood with; I'll pick the 1350mm side - hence its the 3300 that i'll divide with 600)
>> (3300 / 600 )+1 >> 7. (THIS MEANS, I need 7 number of 1350mm wood) >> 1350 x 7 = 9450mm (I need total length of 9450mm wood & each wood is going to be probably 3000mm long >> this means I need 9450 / 3000 >> 3 length of 2x3 wood for slab S1.

Lets calculate S1 again picking 3300 as our alignment - hence we divide (1350/600) + 1 = 3
>> 3300 x 3 = 9900mm (total length of wood needed)
if wood is 3000mm long, then we need 9900 / 3000 >> 3 length of 2x3 wood for slab S1.
1 x 3 = 3 lengths needed.

ALWAYS APPROXIMATE TO THE NEAREST WHOLE NUMBER.

LETS calculate S2 by quicker now.
3300 by 3300, we align to the first 3300 and divide the second 3300mm by 600mm spacing.
>> (3300 / 600) +1 = 7
>> 3300 x 7 (the 2nd 3300 was used) = 23100mm of wood needed
>> 23100 / 3000 = 8 lenght of 2x3 wood for slab S2.

SLAB S3
>> (3300 / 600) +1 = 7
>> 2400 x 7 = 16800mm of wood needed
>> 16800 / 3000 = 6 length of 2x3 wood for slab S3.

Now; calculate for SLAB S4 to S12
S4 = 3nos, S5 = 8 nos, S6 = 3 nos, S7 = 8 nos, S8 = 3 nos, S9 = 2, S10 = 10, S11 = 4, S12 = 8 (Total = 49 nos)

OTHERS (2x3 wood)

There are additional usage for 2x3 wood, in the mallam steps = 10 (approx)
and cut into sizes of 225mm (used to hold the beam in place) = 10 (approx)
in Staircase = 5 (approx)

TOTAL 2 x 3 WOOD TO BUY = 91 nos >>> BUY 95 PIECES

3. 1 by 12 PLANK
A. FOR BEAM:
Estimating for beams isn't that difficult, all we need to do is get the TOTAL LINEAR LENGTH of the beams (additions of all the lengths of beam 1 to beam 16) AND divide by the length of 1 plank (3000mm).

So; Beam1 = 9000, Beam2 = 3300, Beam3 = 3900, B4 = 9600, B5 = 3300, B6 = 9600, B7 = 9000, B8 = 12900, B9 = 12900, B10 = 4875, B11 = 3300, B12 = 1500, B13 = 4050, B14 = 5100, B15 = 3525, B16 = 4275.

TOTAL LINEAR LENGTH OF BEAM = 100125mm (saved this length, we would use it again soon)
Number of planks needed to cover 1 side of the beam >> 100125/3000 (length of 1 plank) >> 33 planks (BUT THERE ARE 2 SIDES TO A BEAM)
Hence; 1x12 planks needed for beam = 66 nos (we would add for waste later)


B. FOR SLAB:
The fastest way to calculate for slab is to find the area of the slab and divide by the area of 1 plank OR you can calculate for each Slab 1 to 12). I'LL SO AN EXAMPLE OF THE SLAB1 -12, then use the TOTAL AREA option.

E.G Area of 1 Plank = 3000 x 300 (LxB) = 900,000mm
Area of Slab S1 = 3300 x 1350 = 4,455,000
Number of 1x12 plank = 4,455,000 / 900,000
= 5 Planks

Slab S2 (another Example)
Area of Slab S2 = 3300 x 3300 = 10,890,000mm
Area of plank = 900,000mm
Number of 1x12 planks = 10,890,000/900,000
= 12 Planks

I'm going to save time and disregard the two examples above for a shorter method (DISREGARD S1 and S2 ABOVE)

PLANKS NEEDED FOR SLAB:
TOTAL AREA OF SLAB / AREA OF 1 PLANK
Total area of slab = (12900 x 9000 ) + (600 x 4275) >> 116,100,000 + 2,565,000 = 118,665,000
Hence >> 118,665,000 / 900000 = 132 planks (we would add for waste later)


C. FOR EDGES OF SLAB:
In the case of side to slab (150mm thick except otherwise stated in the structural drawings). The plank is sawed (cut) to size at the sawmill; this helps the bricklayers when casting the floor and acts as a level. You could also use as it is BUT you would be required to use a nail to mark out the 150mm level.

Since the plank is used along the PERIMETER of the slab, all we need do is add all the sides of the slab to get the perimeter.

from our plan; Perimeter = 12900 + 9000 + 3525 + 600 + 4275 + 600 + 5100 + 9000 = 45000mm
i.e how many planks of 3000mm long would be required to fill the above length ?
>> 45000 / 3000 = 15 nos. Its advisable to add 1 to it because its sliced to size and better than repeating the process.
Total planks needed = 16 planks (waste added for already)

D. FOR STAIRS AND TEMPORAL (MALLAM) STAIRS:
Lets assume our stairs is 900mm wide (thats the size of 3 planks - note that if its 1200 wide. its 4 planks side by side)

The average staircase measures about 6000mm long (minus landing) hence:
>>> 3 planks side by side and 2 planks long = 6 planks + about 4 planks for landing and side, should do the job.
Hence = 10 planks

for Mallam stairs, the difference is much EXCEPT thats would be wider than 900mm, minimum is 1200mm, hence:
>> 4 planks side by side and 3 planks long = 12 planks + about 2 for landing should do
Hence = 14 planks

TOTAL PLANKS NEEDED ON THIS PROJECT = 66 + 132 + 16 + 10 + 14 = 238 nos
Don't be an Ijebu-Man like me; CONSIDER WASTE and BUY >> 250 PIECES

4. 8mm OR 10mm IN RINGS
From the design our beam is 450mm x 225mm HENCE our ring would be 450-50mm x 225-50mm (where 50 is gotten from the concrete cover of 25mm on all the four sides of the ring. (OUR RING = 400mm by 175mm).

Calculate the perimeter of the ring = 400 + 175 + 400 + 175 = 1150 (add 100mm for overlap of rings) >> 1250mm long.
What this means is that, to produce 1 ring, I need 8mm or 10mm rod of length 1250mm. (BINGO)

The design also used ring spacing at 250mm (or as designed by the structural engineer).

REMEMBER OUR TOTAL LINEAR LENGTH OF BEAM IS = 100125mm
Hence >> 100125 mm / 250mm (spacing) gives us the total number of rings needed.
>> 401 rings are needed but ONE ring is 1250mm long
Hence: 1 lenght of Iron (12000mm) long can produce 9 rings. (i.e 12000 / 1250)

IF 1 IRON ROD PRODUCES 9 RINGS, HOW MANY RODS IS NEEDED TO PRODUCE 401 RINGS ?
Ans = 401 / 9 >> BUY 45 LENGTH OF 8mm/10mm

5. 16mm BARS IN BEAM
Also from our design (except otherwise designed), we have 4Y16 = 2 bars of 16mm top and 2 bars of 16mm bottom = 4.

LINEAR LENGTH OF BEAM = 100125mm
1 LENGTH OF 16mm ROD -= 12000mm
We need 100125 / 12000 to fill the entire length >> 9 Bars

there are 4 bars to fill, hence we need 9 x 4 = 36. BUT DEY OOOHHHH

This particular bar has a lot of overlap, so we would allow 20% for overlap = 6 bars.
TOTAL NOS OF 16mm NEEDED >> BUY 42 PIECES


6. 12mm IN SLAB
Calculating 12mm in slab, need a little technicality, you need to have an idea of how the work is done, but here is a simple task you can always do.
A. Find the width of the slab (in this case, its 9600mm), add 1000mm for return on both sides (1000 x 2 = 2000). IF THE ANSWER YOU GET IS MORE THAN 12000mm (YOU'LL NEED TO ADD ANOTHER 1200mm for overlap (i.e 600 x 2 ) where 60mm is sufficient overlap for 12mm rebars.

In our slab >> 9600 + 2000 = 11600mm (so we dont need to add for overlap because 1 LENGTH of 12mm rebar would complete 1 line.

From the design; our bars are spaced at 150mm C/C (centre to centre), Hence >> How many lines of 150mm would fill the LENGHT (12900mm) of the slab ?

>> 12900 / 150 = 86 lines of rebar is needed. We established earlier that 1 rebar would do 1 line hence: 86 x 1 = 86 rebars is needed along the width.

Rebars needed along the legth >> 12900 + 2000 + 1200 = 16100mm (i.e Length of slab + return + overlap because the 1st 2 added is more than 12000mm)
What the above means is that we need a bar of 16100 for 1 line = 16100/12000 = we need 1.5 bars per line (WE NEED ONE AND HALF LENGTH PER LINES)

Number of lines = 9600 / 150 = 64 lines >> 1.5 length x 64 lines = 96 rebars needed along the length.

TOTAL REBAR NEEDED FOR SLAB = 86 +96 = 182 LENGTHS.

Add another 10 bars for staircases and waste >> BUY 192 LENGTH OF 12mm

Note: I didn't deduct the VOID around the stair-hall because it covers for the extra double return needed at that point.

7. GRANITE, SAND AND CEMENT IN BEAM & SLAB
I have so many previous tutorial on this already, there is no need occupying space (I'm sure you all agree - if you need the details, kindly refer to this post and apply same principles >> https://www.nairaland.com/5818635/estimating-cost-fencing-6-plots

Volume of Concrete = 18 cubic meters (m3)
GRANITE = 45 tonnes
SAND = 20 tonnes (if complete, I'll advice 30 tonnes cos it wont be complete)
CEMENT IN BEAM & SLAB = 110 bags

8. OTHERS
Binding Wire BUY 1.5 BUNDLES; it should do the job
Nails - 3 bags (various sizes: 2 inches = 1.5 bag, 3 inches = 1 bag & 4 inches = 0.5 bag)
Water - Get 4 tanks on standby
