Nice job, well written.

Hajji M.

THANKS Hajji boss

Poshriel:
Can you help with prices

Tiles prices differ, depending on quality, size, makers and location etc....

More Of This @Op

thanks sir

bonnyhope:
educative.... how do i save interesting topic on my laptop/phone for reference

click on follow post or save links in evernote (phone app)

mcgaius:
No provision for tile spacing in your calculations.Besides you can access tile calculators on Google and key in the figures.

Spacing is not considered in calculating tiles - not all tile works have spacing too.

On you claim about google, someone took his/her time to program that formula on google - if he didn't, there would be nothing to key into.

if you appreciate google for that, then you should appreciate my effort in this too...

nextstep:
You don't have to have exact numbers, but I think it's always good to have a bit more info... as in they may over quote the number of tiles needed, or even the labour. Trust your engineer, but verify.

OP great work here on educating us. I also really like this plan - it's very well laid out.

Thanks - On the plan, if you need the working drawings; my contacts are in my signature - well appreciated sir

Nice Job OP.. I commend you for your efforts. I couldn't go through the entire write up.. My observations; which remains the fact concerning tiles and tiles business..
400*400 has 12pcs in a carton and its 0.4*0.4*12 is 1.92sqm its floor tiles and can be used for rooms floor, toilet/,bathroom floors,etc.. Price range is between N1100 to N1800 per square metre.
600*600 contains 4pcs for floor(sitting room) and any other rooms of choice.. 0.60*0.60*4 is 1.44sqm per carton..

300*600 floor is 8pcs
20*30(outdated) wall
25*40 wall 15pcs.. (Nigeria and China) 1100 to 1200
20*60 10pcs or 12pcs Spanish N2500 to N2700
1200*600 and other sizes..

Also marble /granite tiles for floor in different sizes.. Even for staircase and kitchen cabinet.. You can actually use N28,000 to buy marble for kitchen cabinet..

For further enquires contact us..Reachout Marble Nigeria Limited.. 08030901894 WhatsApp/call.. We are in Lagos.. Just beside Union bank Coker branch, Lagos badagry road, Orile.. Try the company name on google map and your a stone away from getting the right tiles and at cheaper prices.. My name is Donald..

Thanks for your help, well appreciated - hope market dey move..

famouscargo4u:
Thank you so much OP. This is what i need at the moment.

uwc boss

thedio:
God bless u. This is what av been trying to calculate for days now

Amen, if you have difficulties, u can always DM me

dasoul:
Thanks for sharing bro. It was really informative. We need more of this on nairaland.

Thanks, you can read more of my articles - see my signature

metroid:
Thanks OP

dejonathan:
This trend is not suppose to be on front page...How do you expect we wey dey do the work to dey see extra small small change from tiles

what is yours - wld never leave you..

deal with it sir...

makavelli80:
So it must always be a white man when it comes to advert

apologies, I just used the 1st pics that google gave out...

ditto: pics credit to google

ornicus:
What about screeding.shouldnt you calculate that as well since it forms part of the cost of tiles? And your metal wetin call for the corners and edges? And your white or black cement?

To avoid variation matter

Well done

my style has always been to break down my lectures to a particular item or topic - if we put all the elements in one piece - WAOH.

People are already complaining this is TOO LONG - imagine if it was all-inclusive.

I'll create another lecture on that, just follow

Puregold3:
Awesome info..
how do I also calculate the amount of cement needed to complete a building?

I've put up so many lectures that can help with that; check my profile for links to all my post here on NL or on my blog (see signature) - you cld contact me also, if you prefer we do it for you.

Thanks

Amuatulu:
Amazing calculations.
How many pcs of tiles do we need for the whole nairaland website.

thanks for the compliment, to your question Seun wld have to tell us how big the Nairaland floor is... then; Bingo

holina:
op . u taking food from quantity surveyors mouth

Then we shd close down google, youtube so every1 would still have a job....

GoodDay and its good to be back.

Let's go practical (as we always do) - calculating the number of tiles needed to tile various spaces within the building (floor and wall tiling).

We would make reference to our 3 bedroom plan, designed specifically for Nairaland lectures and calculate the tiles needed in the living room, one of the bedrooms and the master's toilet's floor and wall tiles.

www.nairaland.com/attachments/4619535_3bedrmsketch_jpeg4f34cd145ab26509501bebe01065e196

SELECTING TILES

1. Tiles come in various sizes, the common ones being 150x150, 200x200, 300x300, 150x300, 200x400, 300x600, 400x400 and 600x600; the first thing to do is pick a tile (based on clients choice or use) for each floor and wall. There is no rule stopping you from using any particular tile size for floor or wall, as long as it has the perfect surface finish for that use.

e.g, a glazed (slippery) tile is not appropriate in the bathroom, so if I find any non-slippery tile, irrespective of the size, I can use it for my wet floors. Wet floors include Bathroom, Swimming pool, Laundry, etc. (We've had buildings where 600x600 tiles were used on the wall and 150x150 tiles used on the floor) - in summary, the tile finish NOT the tile size determines where it is used.

2. Select tiles for each space. (Let's select ours too).
I'll go with the popular opinion; Living Room (600x600), Bedroom (400x400), Bathroom Floor (300x300) and Bathroom Wall (200x400).

Note:
* Glazed tiles cannot be used on wet floors - it's very slippery if the floor is wet and dangerous
* Un-Glazed, Matte, Rough tiles can be used on any surface (wet or dry)

3. Calculate the area of the spaces (floor and wall) separately - This uses the simple LxB (area of a rectangle principle) - and write it out.

Note:
* Remember to deduct door and window openings where applicable (e.g Area of wall = 10m2; area of window = 0.5m2 therefore area to be tiled = 10m2 - 0.5m2 = 9.5m2)
* After getting your area to be tiled, ADD 10% of quantity for waste & broken tiles. (e.g 9.5m2 + 10% of 9.5m2 >> 9.5 + 0.95 >> 10.45m2)

4. Calculate the Total area of Tiles you're picking; this varies from one manufacturer to the other and from one product size to the other. >> this means that while 400x400 tiles from SaydFact Ceramics contain 11 pcs, those of Teewhy2 Tiles Ltd might contain 13 pcs - It is, therefore, important to know how much pieces each pack of tiles you're buying contain.

5. Ascertain the total area of one pack of tiles (either by calculating or checking on the pack), use this figure to divide the total square area of the room to be tiled and the result gives you quantities needed - in simple terms >> (AREA OF LIVING ROOM / area of 1 pack of tiles) = Quantity of Tiles needed (remember to add 10% for waste).

LETS NOW GO PRACTICAL BY CALCULATING USING THE ATTACHED DRAWING (see pics below) and information in No2 above.

A. Master's Bedroom:

* From the diamond below; total floor area of Master's Rm is 13.20m2
* Lets agree that our 400x400 tiles contain 11 pieces; hence area of 1 pack in meters >> 0.4m x 0.4m x 11 pcs (400mm is same as 0.4m and area of 1 tile is 0.4 x 0.4, while the area of 1 pack is (Area of 1 tile x number of tiles in 1 pack)

1 PACK = 0.4 x 0.4 x 11 = 1.76m2

Number of tiles needed to complete Master's Rm floor = 13.20 (divided by) 1.76m2 = 13.20 / 1.76 = 7.5 packs

before we add for waste; let's calculate skirting for the Bedroom using 120mm as skirting height.

* The 1st question is how many skirting can we get from 1 tile?
Ans: Lenght of tiles / Height of skirting = 400 / 120 = 3 skirting from 1 tiles.

* What is the perimeter of the space needing skirting?
Ans: From the diagram, bedroom is 4150 by 3150 hence perimeter of room = 4150 + 4150 + 3150 + 3150 = 14600mm

* Deduct openings from the perimeter ie 2 doors (toilet and bedroom doors) where there won't be need for skirting >> 750+900 = 1650mm

* Length requiring skirting = 14600mm - 1650mm = 12950mm

* Numbers of Skirting needed = 12950 / 400 (lenght of 1 tile) = 33 pcs (approximate to the next whole nos)

* Number of Tiles needed to make requirement = 33 pcs / 3 (number of skirting gotten from 1 tile) = 11 pcs (11 tiles are needed for skirting)

* Number of packs needed for skirting = 11 pcs / 11 pcs (number in 1 pack) = 1 pack is needed.

TOTAL TILES NEEDED FOR MASTER'S BEDROOM:
7.5 PACKS (FLOOR) + 1 PACK (SKIRTING) = 8.5 PACKS.

ADD 10% FOR WASTE >> 8.5 Packs + 10% of 8.5 = 8.5+ 0.85 = 9.35 packs needed

HENCE BUY 10 PACKS (approximated to the next whole number because you can't buy half tiles)


B. Living Room: (Straight to Biz)

We're using 600x600 tiles and each pack contains 4 pcs; hence Area of 1 pack = 0.6x0.6x4 = 1.44m2
Area of Living Room (see diagram) = 22.02m2

* Number of Packs needed for Floor >> 22.02 / 1.44 = 15.2 packs

Skirting >> Perimeter of Living Room - (All Openings) = 12.2m or 12200mm

* Number of Skirting in 1 tiles >> 600 / 120 = 5 pcs (from 1 tiles)

* Number of skirting needed for Living Room = 12200 / 600 = 21 pcs

* Number of Tiles needed to meet requirements = 21 / 5 = 5 tiles

* Number of packs needed for skirting = 5 tiles / 4 pcs (number in 1 pack) = 1.25 pack is needed.

TOTAL TILES NEEDED FOR LIVING ROOM:
15.2 PACKS (FLOOR) + 1.25 PACK (SKIRTING) = 17 PACKS.

ADD 10% FOR WASTE >> 17 Packs + 10% of 17 = 17+ 1.7 = 18.7 packs needed

HENCE BUY 19 PACKS (approximated to the next whole number because you can't buy half tiles)


C. Bathroom Floor: (using 300mm by 300mm Tiles)

Area of Floor / Area of 1 pack of Tiles >> 3.26 / 1.35 (assuming nos in 1 pack = 15nos) = 2.4 packs

There's no skirting in Bathroom because we have wall tiles.

TOTAL TILES NEEDED FOR BATHROOM FLOOR = 2.4 + 10% of 2.4 = 3 PACKS


D. Bathroom Wall:

We're using 200x400 tiles and each pack contains 17 pcs; hence Area of 1 pack = 0.2x0.4x17 = 1.36m2

Let's also assume that we're tiling up-to 2.1m only i.e Window level (the alternative is to tile up-to 3m; i.e ceiling level)

* What is the perimeter of the space needing wall tiles?
Ans: From the diagram, bathroom is 2100 by 1500 hence perimeter of room = 2100 + 2100 + 1500 + 1500 = 7200mm = 7.2m

* Find total area to be tiled >> Perimeter x Height used >> 7.2m x 2.1m = 15.12m2

* Deduct Area of openings from the Area above i.e 1 door (2.1m x 0.75m) and 1 window (0.6m x 0.6m) >> (1.6m2 + 0.36m2) = 1.96m2

* Hence; Area to be tiled = 15.12m2 - 1.96m2 = 13.16m2

Now we revert to our earlier formulas i.e AREAS TO BE TILED / AREA OF 1 PACK = NUMBERS OF PACKS NEEDED

* 13.16m2 / 1.36m2 (area of 1 pack) = 9.7 packs = 10 packs (approximate to next whole number)

TOTAL TILES NEEDED FOR TOILET WALL: 10 PACKS

ADD 10% FOR WASTE >> 10 Packs + 10% of 10 = 10 + 1 = 11 packs needed

HENCE BUY 11 PACKS


Do the above for all space in the building; You can even prepare an excel file with the formulas so you won't need calculations each time; just input the area of floor and area of tiles and bingo.

Thanks for Following...

345m is a mini-stadium - that's BIG

jp130:
Thank you so much boss, I really appreciate this.
May God bless you this day in Jesus name, amen.
Please the reenforcement bars, u mean i wud need:
2nos of 8mm or 8 nos of 9" 12mm ready made rings and 16 nos of 16mm rods? Plz clearify dis items for me, tnx

Morning..

buy:

2 lengths of 8mm OR just buy 3 dozen of ready-made 9'' rings

8 lengths of 12mm

16 lengths of 16mm

Goodluck

jp130:
Nop, it is not water logged. Solid ground sir, tnx

Morn Boss;
Here is your material schedule up-to german floor level (OR the concrete beam over blockwork as you requested)

MATERIALS:

Cement in Ground Beam ie Fondation Footing = 35 bags (using 150mm as thickness) OR 45 bags (using 200mm as thickness)
Cement for Block Setting = 16 bags
Cement for Concrete on blocks at DPC level = 12 bags (using thickness as 100mm ie 4inches) OR 55 bags for German Floor)

Block in Foundation = 990 nos (using 4 courses as the basis)

8mm Rebar in Starter Column = 2 nos OR purchase 3 dozens of ready-made 9'' rings
12mm Rebar in Starter Column = 8 nos (using 12 columns for calculation - ie just the pent floor area)
16mm Rebar in Starter Column = 16 nos (that's the exact nos needed buy 1 more incase of waste)

Granite = I always advice 30 tonnes BUT 15 tonnes would be enough for the Foundation works (without a full german floor)

Sharp Sand = 40 tonnes OR 2 nos of 10 tyre Tipper

Add N20,000:00k for setting out (if done the right way with profiles, pegs etc)

Budget 5 Tanks of Water @ N2,500 each for the project if there no free water source around


WORKMANSHIP:

Negotiate and ask for advice later.

Goodluck

NOTE: We design and build also

Muyi002:
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.

If i had the info here, I wld have done the calculations - unfortunately I dont - thats why I narrated the principle. I'm not a fan of In-situ concrete parapet so I have less info on the material use ready.

Alternatively, ask the workmen for material schedule and share.....

we both can learn 1 or 2 things from them.
thanks

Muyi002:
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

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)

jp130:
Tnx sir, here it is.

I'm assuming the soil is a good one and I'll use strip foundation and send soon - if its a waterlogged soil, let me know soon.

Goodluck

when we say donate - was it done with his personal money?
na question oooh

Nice compilation but there are even some more - didnt capture all but well appreciated

na wa ooohhh

9ja is gradually collapsing

Muyi002:
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

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.

jidobaba:
Please i need a little clarification. For a bungalow already has pillars at the sides. Are you saying that chain lintel must be done for parapets? Or we can do the normal spaced lintel? Or what do you mean by beam?

Do the normally spaced lintels...

If you want to do a concrete parapet - the workmen/specialist would advise you accordingly

FOR NOW; DO THE SPACED LINTEL irrespective
