Tbh, your engineer will have serious issues with your approach to construction.

The information you shared above is incomplete and it seems to me you just want to prove the engineer is insincere at all cost.

If you don’t trust him, get someone else and build your house and stop acting construction police.

So far so good, the guy has not done anything wrong. He has stated his term of engagement and it’s you who can’t meet up.

At this point, I wan off mic.

12k for DPC?

Abi I’m dreaming ni? 100mm thick or just 25mm? Regardless the size of the building I have NEVER budget anything less than 50k for DPC. (Read this part slowly)

Below is what DPC look like even in the government affordable housing scheme. You’re not allowed to manually mix concrete. I do minimum of 8 concreters for a 100sqm footprint.

Machine Operator - 1
Cement - 1
Water - 1
Granite - 1
Sand - 1
Loader/Carrier - 3
Bricklayer (leveling) - 1

Where will you get casting crew that’ll accept N1,500.

@segzyfunmi this is reason why you need to share your building plan. Even if it’s a sketch.

diordaves:
Without the plan, the figures here are just ballpark figures but this will give you an insight into how this is done:

#Digging the foundation of 3 bedrooms aim for 50k.
(In Abeokuta, this might be tricky as the town can be rocky and difficult to dig but then again, because of the terrain you may not need a very deep foundation to get to stable soil).

Blinding aim from 35k

The setting of foundation block: I don't know how big is you flat, but let's guess 1300 blocks with a high foundation. To lay one block is N50.
so 50x1300 = N65k

Iron Bender to tie the basket and columns: aim from N35k

Carpenter formwork aim from: 10k

The casting of the Columns: For three bedrooms, depending on your design, your total columns should be around 16 columns. To cast one column aim from 1k per column.
So 1x16 = N16,000

Foundation and back filling aim for: 15K


Wetting of foundation (compacting) - 1k

Casting of German floor aim from: 10k

Total Labour: N237k

These figures are highly debatable but hopefully, you should now have an idea on the direction of travel.

Amastermovic:
BLINDING COST 35K y is casting of german floor now 10k pls guide me .

segzyfunmi:
Sub structure only to DP. Engineer's job is to supervise the Carpenter, Mason, iron bender etc to DPC level.

My question remains the same pls.

Is 700k not too much for labour and supervision??

PrimeQuay:
Happy Sunday,
This point you raised is the bomb. Engineer's deliberately inflate the cost to increase their percentage due to them



I totally agree with this point of view i.e engaging a QS who is independent of the project.

However in my limited experience, bill of material and labor does vary from QS to QS. how does one eliminate inconsistencies.

Ive also noticed that engineers might markup labor costs (especially) in order to increase the total, resulting to a higher figure if they are working on %.

You saidbthe ground is hard and also you van be on ground to supervise it also. So no one is cheating here. But the engineer fee is it just foundation or to take it to DPC. You have to know his deal first. Cosy of materials is on the high side and also that amount can take you to decking if spend well. Me am in benin city. You can text for more inform

QSFemi:
Happy Sunday.

As regards the situation, I have said it times without number that it's advisable for clients, project sponsor or home owners to hire independent professional to assess the construction cost of their projects especially in a relatively high end construction.

To have a contractor to submit his quotation for a project to a client, to be assessed, who has no knowledge of construction processes will not be fair to the clients at all. Even if the clients insist on buying all the materials as quoted and subsequently monitor the usage of such, there's still no way for the client to know the fair cost of required labour for such project. Hence, the client is still very likely to lose a good amount of money to labour cost.

That's why professional Quantity Surveyors are trained to be an independent cost assessor of construction enterprises which ranges from building to roads, bridges to railway, and what have you.

In your case, the best bet is to let us have the drawings and advise on the cost consequently.

As regards 5% supervisory fee, it's subject to review. However, in a standard contract with reputable and registered construction firms, 15 to 35% or even higher (case in point: Julius Berger) is normally charged to the actual cost of construction for overheads and profit.


Thanks for your input. The drawings are with my uncle at the moment. Is there no way I can get an approximate value for the labour cost? Pls read my first post for the description of the job to be done.

diordaves:
Taking another look in regards to your response, I can now infer that the BOQ states the foundation cost is 3 million. So 5% of 3 million is 150k. I got this wrong then. But the focal elements of my take are in order:

# BOQ should be prepared independently of the resident engineer/builder.

#Circa 100k is a decent fee for the supervision.

# It is advisable to get further quotes.

Chekitaut:
Am in Abeokuta will guide you accordingly. You will surely need an engineer.

I will supply you best quantity & quality materials.

Even the state government didn’t offer registered state contractors N2.5m as upfront for a semi-detached unit.

He won’t exhaust the 2.5m to finish the job in Abeokuta so make him an offer he can’t refuse.

“Take it or leave it.”

If he says no, there are hundred of competent engineers who are ready to kickoff on Monday morning in Abeokuta. If you can’t find, just go to the Ministry. I’ll give you contact of a director in the ministry of housing to work with.

Don’t let us ask you to share the plan and use scissors to cut down the cost
