Good mornin family, I need your help for my roofing project. My engineer is one guy that I don’t understand. Can you please help me with this quotation for the roofing of this small project? I have attached the house plan for easy assessment. I will be happy to hear from everyone soon. The house is on 30/120 and the size of the house is 21/70. Thank you all

Go this way.
Ask him to buy real 2x2 (50mmx50mm) not the so called (“solo” size in the mkt) it’s not good for roofing work. Although the price is btw 300-320.

More so cost of logistic is much if you are buying the wood from itamaga area their in Ikorodu. (Bargain btw 18-22k max)

Workmanship around 120-140k max”

Estimated Figures (Note: I didn't add for waste - it is important to add a little for waste)

Wall Plate (3by4) = 20 pcs
Tie-beam (2by6) = 50 pcs
Kingpost (2by6) = 30 pcs
Rafter (2by4) = 90 pcs
Struct (2by4) = 280 pcs
Purlins (2by3) = 420 pcs (because of the roof covering intended for use)
Ceiling Hangers (2by2) = 220 pcs
Facial Board 1by12 = 0 (because it shows concrete facial)

SUMMARY:

3 by 4 = 20 pcs

2by 6 = 80 pcs

2by4 = 370 pcs

2by3 = 420 pcs

2by2 = 220 pcs

Nail = 1 bag 4 inches, 1 bag 3 inches, 1 bag 2 inches (I DIDNT CALCULATE, I'M JUST SUGGESTING )

Oja Agba = 3 - 4 dozens

FINAL NOTE: This are my quick estimates, might not be exact numbers needed because I didn't consider wastage..

GOODLUCK

The pictures looks OK to me, soil is a rock AND THE COLUMN POINTS have extra depth..

rotecch77:
Foundation trench standard width is 675mm

Foundation depth varies according to your site topography ( but btw 450mm-500mm).

Column pit depth from NGL also depends on your site but standard is 1meter.

Column width also depend on the design from your structural details ( columns are varies)

twinskenny:
never heard of it

topsy23:
NWC is good but can't compare it with Coleman, Nigerchin and Kabelmetal

Denki wire and cable saw it once but I don't think it's the class with what I lusted above..

ganie:
Please what is the usual cost of labour for plumbing works.
The work to be done is the laying of pipes from 2 toilets to the soak away and channeling of the necessary pipes for water.
I hope a plumber can contact me.

Dubemcapital1:
So sorry I didn't respond promptly, I was so much engaged.

Well, a lintel that is well chained all over is more than just a lintel, it's a binder and a support system to the entire structure.

Nevertheless, if your house dose not have a concrete fascia or parapet, slab on the roof, metal roof frame, or the house is not very massive, there will be no need for roof beam you can use a well chained lintel (lintel iron bar locked up to the columns iron bar)

Meanwhile you can use a wall plate (hard cord 6*4*12 wood as the roof beam, well placed on the leveled courses (final block before the roof) and form your roof framework on it.

Hope this will be helpful? Apologise for late response.

Thanks so much sir
Just wanted to know which is best btw terminating the columns at lintel level or taking it to roofing level, since I won't be doing roof beam, as I have got so many contradictory response on it

saydfact:
Take it to the roof level....

Dennis3D:
Yes. Depends on the shape and size of the plot.
Let me show you a big Duplex on Half plot

davodyguy:
Hello guys

Can I get an estimate for this from substructure to superstructure?

Land are is 9.25m *37m
Foot print of building is 29m*7m x 2 floors(Ground Floor and Upper floor)
Land is located in water logged area in Lagos, hence foundation needs to be solid and as high as 1 metre after the Natural Ground Level

Thanks

Omonjoe:
Thank you bro. The builder is actually a family friend and he was trying to cut cost in whatever area possible.
I might just do it then. So with the german flooring, I will have to go straight to tiling after building?
