Thank you for the recommendations.
I have decided to go with Gabropka001 because I love some designs he posted.

If anyone has worked with him in the past and was not satisfied please let me know. I love transparency and don't want issues with anyone because I am also a professional.

folmus:
Since he has refunded you, there is no big issue. He is a nice guy here.He might be very busy

Check with these guys if you still need one:

@Biztech05
@Uncleeth
@Nifemiayoade

in no particular order. Do your due diligence.

Yes that's already done

folmus:
Did you build the other two beds and BQ?

You are missing the point.

I am not an architect but this is not my first project. Final delivery duration is two weeks. A sketch must be sent before then to make corrections.

The issue is not the two weeks but I had to constantly ask for the sketch and he didn'tcommunicate unless I did. When he eventually sent it, he didn't take into consideration any of the things I specifically wanted and didn't want. For example, No ante room, round shape balcony.

I was convinced that he sent something he already had before. Even the floor plan had no measurements.

FYI: I have worked with another vendor on nairaland and never complained. I am not saying Mr. Raymond is not good ooo but communication is key.

I only posted on Nairaland because he sent me a voicenote which I found disrespectful. "He is the special advisor to Rivers governor, Gov is his uncle so he is busy and does things besides architecture. people in diaspora blah blah" he is not an hungry man.

Like wetin we carry?

Kingdemu:
But from Sep 9th to now is not 2wks na

Yes, he refunded because he hasn't done the work. I am a legal professional so I know.

Moreover, not everyone wants a refund. Some people want their job done as agreed.

You've done well by refunding her.[/quote]

Raymondfirstborn

He immediately refunded the money but that's not the issue. I paid him on Sep 9, he said the entire duration was 2 weeks but would send the sketch in few days. I asked him some questions on Sep 10 and didn't contact him until Sep 15. He promised to send it on September 17. I didn't hear from him and sent him a message. He sent me a rough plan different from what I specifically requested. I knew it was a rush job. He sent me a 3d design that I have already seen online without including the specific balcony design I wanted. I hate to harass anyone but then sending me a message about "me harrasing you and how busy you are blah blah is not professional". As a professional, you must be able to balance work and task. Most importantly, communication is very important.




Floor plan should take 3 to 5 days. I am the one who constantly send a message to this man. I understand that "he is busy." I don't like harrasing people but I

Please, mention name. You will be supporting and abetting bad behaviour if you are making it cryptic. Shebi you don pay?[/quote]

I am very disappointed with a specific architect on this platform. I saw a design he posted in 2020 and have been communicating with him since then.
I decided to give him a chance to desgin my project and I have to be the one constantly chasing him down for a sketch after almost two weeks. Professionals need to do better. If you are busy, do not take a job. No one wants a rush job because by doing that you're creating an insecurity in your client.

I bought a plot of land in 2020. I have almost completed the building, Is a C of O required?

Does anyone have a picture of a straight parapet vs curved parapet? What is the difference? Is the extra cost for a curved one worth it?

Great job. Are you a quantity surveyor?

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

GOODLUCK.

No, the Engineer I used started to inflate prices and materials so I couldn't trust him again.

bixton:
I think it's best you bargain with him slightly. Except you have doubts about his capacity and capability.

There's always someone to take a less amount but the output is what matters. Some buildings form work/walls are so unsightly that it's only at the plastering stage that the non-sense work is hidden if at all it can be hidden.


Is the engineer not the same person who used for the substructure(foundation level)?

Happy New Year!

Please, how much is the average fee for Engineer's SITE SUPERVISION ONLY?

Construction stage - ground floor blockwork to lintel only
Duration- two weeks
Location- Ikorodu
Project- 4 bedroom Duplex + 2 bedroom flat AND BQ

An engineer quoted me 500k, I believe that is too high.

I only included the Duplex in the plan and was approved. Never had any issues since then.

amakaDD:
How did this go eventually, would love to know. Kindly share.

Please where are you located? I need some cements at Ikorodu

n3xt:
Its now N3,050 per bag at my end. Information from a reliable source said this might extend till February 2021.

It’s already taking a hit on us here as our block makers now manage to get 400 bags per week.

The total blocks and cement for the entire ground floor

Heymus:
.you mean the blockwork on this german floor?. If yes, we used 550 9inches block and 10bags of cements.

How many blocks and cement did you use for the blockwork

I totally agree with you. It's very discouraging when you decide to do something good and all people care about is ripping you off.

n3xt:
Interesting!

Ladyteeks, if I were you I’d consider engaging a QS to mange this type of project since you’re not fully on ground

If a middleman is involved, I’ll also disengage such person. They do more harm than good.

I am really grateful for your input.
Well detailed too.
God bless you

One4me:
I am just happy for you, l know its a bigger challenge when a lady is building though l expect that service providers will be less aggressive on them, with pricing.
Consider engaging QSFem for a fee, to supervise what you are doing, if you will, l believe you will get the long term benefit and l hope he also can oblige. Your project seems sizable and complete carcass is just about 40% + or - 5% of your total cost, so l wont like any cut-throat Service Provider to take you to the cleaners.


Caveat: the above is just my opinion, dont know him, never met him but l have been impressed by his conduct and service to many members here. Perhaps l am just feeling funky and a little drunk today, who knows.

I am really grateful to everyone who has helped me on this thread. May God bless you and your household.

Thanks so much for your help.
I am not an expert in building. Everything I have learnt is from nairaland.

I belive the blocks needed was overestimated, but QS femi and I are working together on it.

One4me:
Blocks might have been over-estimated! Cant you estimate the number required, by yourself?

You should not pay more than #60/per Block, never and for the fact that the number is large, in the thousands, you should negotiate and not pay more than #50, max #55.
Again, how much you pay an iron bender or Carpenter, will depend on the number of Pillars and Lintels you will be doing.
What you can do is to negotiate separately with your own, sourced Iron Bender and Carpenter.

Its going to be a tough one, if you dont have the knowledge, wont do the trench/brain work (no offense) and wont consult with a QS.

Thanks so.much. QS femi and I are in touch now.
I confirmed again from the engineer and he said the 8500 blocks is to lintel level ONLY, not the entire project.

diordaves:
I think you should consult QSFemi to have a better understanding of the process. His take so far is nearer to the true cost outlay.

Now mind you, don't get confused by it all. In your initial query, you said your engineer invoiced you 1.1m for labour to LINTEL LEVEL only for block setting. Then in another breath you said the project is about 8,400 blocks.

Now I observed you and others here are multiplying N70 by 8,400 to get a cost outlay. This is wrong as 8,400 is for the WHOLE project not to lintel level. Or is the 8400 blocks to lintel level?

Furthermore, to lintel level, you DO NOT need a carpenter or iron bender if the initial invoice of one million is for setting blocks only.

You need carpenter and iron bender when you want to cast your columns and beams AFTER block setting. So stay alert. Don't mix it all up.

So sit down with QSFemi to break it all down for you and come back here if you think you are still being bamboozled.

Break it down:
#Labour cost for block setting to lintel level.

#How many blocks to lintel level.

#Labour cost of casting the columns, beams and lintel. (at this point you will need carpenter and iron bender).

#Esterblish from QSFemi the number of columns (pillars) there is. The number of pillars will determine the casting cost just as the number of blocks determines the block setting cost.

It is possible someone is trying to befuddle the whole process to confuse you. And with property, once the homeowner is confused, there is only one outcome.

Sent you a text...

QSFemi:
Please send me a text message on 09012800750 and I'll reply with my whatsapp number.

Please send me your whatsapp number

QSFemi:
Yeah. I saw the attached drawings - the main building and BQ.

Does the ground level include the two bedroom flat as well? I am confused where he got his numbers from. Please note that there are two units in the BQ and the main building is a 4 bedroom Duplex plus two units of two bedroom flat.

Pls send me your whatsapp number

QSFemi:
I checked where I did the calculations again, the total blocks you need to the lintel level for the main building ground floor is 2731 blocks for 9-inch block while you need 914 blocks (9-inch) for the BQ and also 262 blocks (6-inch), also for the BQ.

In summary, the total blocks needed for the ground floor is 3907 blocks to the lintel level.
