yes the tank arrangement is like you said: 1, 1 and two.

The holding capacity of the tower is for about 5500 litres x 4 Tanks, its 5500 litre tank per each three bedroom flats, 2 x One bedroom flats will use one 5500 litres and 2 x two bedroom flat will use one 5500 litres tank. it is a total of six flats.

To be honest I'm not sure of the foundation dept but it is not H-Beam but galvanized

Thanks sir

Question for you guys.

I'm not sure that I've ever seen you guys build a 2 story house without building the lower floor partitions first. Is there a reason why you do not build the pillars and then deck before building out the partitions?

Thanks.

It is advisable to use the method if you are going multiple floors so that your columns can have adequate strength for the building loads.

Why u no talk say u na engineer nau...U con dey deceive us
You are right sir, R may attain maximum strength faster than N, but i believe they will eventually attain same strength, since they are same grade.
I only see R to be suitable for projects with limited time, say one is concreting a floor to be used by vehicles next week, just maybe it will be more suitable to use R.

Greetings my Ogas in the house.

I have been following many threads here in properties section and I enjoy seeing so many constructions going on and I wish everyone both the clients, the contractors and us onlookers good luck in all our endeavors.

But, while we embark on this construction journeys, I ask for us to be aware of site safety. I have seen pictures from different sites where workers are working without shoes(ten toes), in some sites workers are wearing bathroom slippers.

Abeg, site engineers, architects, contractors please lets try and reinforce workers safety on site. It starts with simple PPE.

Thank you!!!

workmen go tell u say e dey delay work.. lol

a few big company used to enforce it..

I remembered an electrical guy who was fixing a fault without glove.. he nearly died not funny that day

gbadexy:

After being assured by the expert in the house that the cracks are superficial, then I could say you either screed the wall or apply a primer coat of thick emulsion in multiple coats.

Which would be cheaper, between screeding and multiple layers of primer Coat emulsion?

peaceland:
Thank you @Chekitaut for this post.
I had a serious fight with my bricklayer over several cracks (tiny funny lines all over the place like spider web).
My initial thought is that he did not use enough cement; he tried to prove he did and then i blamed the sand and him that with his years of experience should have known the sand is not suitable (which was the sand he advised we get anyway).
Now I am thinking I might have been a bit unfair because i know we used the R (although he still should know the nexus between R & cracking anyway)
Now his position is that this can be corrected if i screed the walls; i really do not want to screed anything (cost factor)
my questions are:
1-can screeding help?
2-what other options are available aside from screeding?
thank you

I think that type of cracks is called mapped cracking, this occurs a lot on plastered wall which may be due to the grade of the plaster sand ( very smooth plaster ) that is why we normally add stone dust to our plaster sand to minimize such cracks or due to the the temperature ( during harmattan season the plaster dry quickly due to loss of moisture ).

Such cracks can easily be corrected by screeding the wall after the wall had dried completely.
You don't have to worry about such

Even bungalows can be built using system of frame structure.
The standard way to build any building with suspended floor is through reinforced concrete framing where the columns, beams and the slab are built before the partition walls are added to the construction later. This method of construction enable the structural members to be properly cured, have adequate dimension ( especially beams) and enable the end conditions ( joint between beams and columns to be achieved but it has the advantage of lack of proper bonding between the columns and the adjoining walls but such shortcomings can corrected using a binder

CharlesAA:
Hi Superstars,

we are doing the ironworks for a foundation, its about 2m in height, being that its a waterlogged area of magboro, lagos ibadan road.

now the panel supplier is charging 1k/sqm, calculation for sqm for the framing is about 355sqm.

is this a fair price?

where else can I get a panel for use, so i can do a comparison of the prices.

Are you building a raft foundation? if yes, such price represent a better value for money than other alternative available

Daboomb:

The primer would be cheaper. A drum of N4500 can cover 20 sqm and if made the exact color with the finish paint, the actual paint quantity required would reduce.
A painter would finish a room in an hour technically. Although he would have to wait to apply the second coat, but then he would have covered more areas with the first coat.

Oga Gbadexy,
Thanks for your response.
Who makes the primer; the painter or the paint company?. If it is the company, do you tell them what color you want. Or is primer a particular product you buy differently from the paint or mix with paint color?. How does this work when you have different paint colors in mind for each room.
Pls enlighten us.

Framed structures are faster to build, with few advantages over the block+frame structures, but the cost of materials like wood will increase, many clients looks to reduce building cost so might not agree to it.

Well said sir. carpentry labour could be a bit higher. You need a very good carpenter that is technically inclined. It also require more supervision effort.

Pls enlighten us.

Paint manufacturers make them. Some paint companies have primers as a separate product while some painters just use white emulsion paint as primer.
The primer I mean is not to consolidate weak substrate before final painting, but rather a high solid content paint with sufficient film thickness to cover hairline cracks.
The painters know some low quality brands that are thick on application but doesn't spread far. You could use those or get a ready mixed putty basecoat or flex coat and thin slightly with water then apply with short nap roller, both of which are thick paste like plasters usually applied with trowel.
After application, the painter would need a very smooth sandpaper to smoothen the surface slightly to level the roller mark before painting.
There may be some difficulty in having it on similar color for building with many different colors.
While the ready mixed putty comes in white, flex coat and some brand of paints come in colors.
Basically what you need is a thick paint that can fill cracks and if your painter can handle it, he could mix the powder putty filler or cement with emulsion paint to form a thick paste and use their scraper to apply it to fill the cracks, then scrape off the excess to leave a level surface.
The problem with the latter is that the cracks may be numerous and in places hands can't reach and may take much time to complete.

Adventures and Spyder880, why would the cost be higher? Frame structure approach is building the columns first before block setting right? Is it not the same number of columns with frame approach and block setting approach? Or is the number of columns more with frame approach?

For example if the architectural drawings are 24 columns, would you necessary increase the columns due to frame approach? Then the cost should be same as you still would construct 24 columns or even cheaper as you could save on wood with build and transfer.

Do you think I'm not getting the nitty gritty of it all? If yes, please educate because frame approach is a very beautiful and practical method for budget control and phased building.

You are more than very correct , I could remember back then one of my lecturer asked this question. Frame structure safe cost and if you organize your project very well it will safe time

sir, in frame structure you will need four planks to form each column with a lot more bracing, compare to the other method where you will need two or even one , you will need planks for the soffit of beam but in the other way you don't. Also the concrete is more compacted and you can even vibrate it well. The difference is minimal any way.

I think Aventures has done it before on here. Mainly used for multi-storey buildings. I don't think framed structures actually costs more. Maybe just a little more. It's actually very good. You can finish all your concrete jobs at once.

True. When you're going multi-storey, you can use the planks almost immediately which means you don't have to buy planks all over again compared to when you build together with partitions which may reduce the difference in cost.

I've seen that thread now. Not sure how I forget about it as I was a participant on it.

I think the higher cost is due to the plank used on the side that a brick wall would have been.

I do agree that the Carpenter must be on point and measurements must me fastidiously performed. I like it personally.
