What quantity of iron will deck a 200sqm building?

Exactly 197sqm the following:

16mm = 1.5 tonnes
12mm = 3 tonnes
10mm = 1 ton
Binding Wire = 50kg

Note: Some (not much) 16mm and 12mm iron were left and used for columns (pillars) and lintels.
Full cost about N2.7m started in Dec 2015 and casted in Jan 2016 before all the crazy price hikes.
Done by a reputable Builder here on Nairaland.

For full details and other materials send me your personal email.

Note: This is not in Lekki o. (Na who born monkey ).

I have been having a bungalow + penthouse idea since Nigerian's won't tag u rich until u build one story building

They might decide not to GIVE u baale post because your house na bungalow and Mr taju house na Duplex.

I just gave you an idea of what 200sqm building looks like. It's almost the footprint of 2 executive 3 bedroom bungalows so the slab will cost more than when you want to put just room pent on a bungalow.

200sqm is a lot. I doubt we have up to 10 of such duplexes (standalone) here on Nairaland. The max you'll see is 180sqm.

1. I'm putting this into action from tomorrow when we take on our first flat roof project on here. All the water collection points have been linked up in-wall and under the floor to connect to a central water tank for compound and outdoor usage.

2. Again, I'm putting this into play with my ongoing project where bathroom Windows are largely sized for improved lighting and ventilation. I always opt for projected windows or casement in the bathroom and I keep the slightly opened for constant airflow.

3. I really don't think it's about the cost. One thing I've found out is that we always love to find excuse to why an unusual approach may not work. Someone on here said he's considering using Aluminium sheet to clad his walls without the usual plastering and painting hullabaloos and everyone is looking at him like "what a strange man" but in reality this things are practicable and could save us a couple of bucks. I've seen them used in real world.

I knew how hard I tried to convince my client on the advantages of using lightweight steel roof over timber roofing. But luckily, it was a listening client I had this with. I knew some who would have acted differently.

Central water heater to me would seem to work like the overhead tanks we place on our structures. So it shouldn't be a big deal for a creative mind.

As per electricity, the same light that powers small heaters will power the big ones. They're just like the ACs.

Nice stuff!

@Bolded paragraph:

Brabus, talk to me about this light steel roof!

My understanding is that Steel is denser and therefore heavier than wood.
Now, if you have found a way to do the Roof Structure using Steel of some types.... and it is considerably lighter in weight, compared to using Wood, l will be happy if you can oblige me the information.

Type of steel, what makes it comparatively lighter, cost implications compared to using wood and other advantages you have deduced.

Thanks!

My top three wasteful build/design concept in rental properties in Nigeria:

3. Wall lamps

2. "Parapet"

1. Mortar use during block setting

Parapet and mortar use have been debated a lot here so can I ask why in Nigeria do we install all round wall lamps? It's not uncommon to see in Nigeria an average living room with 8 lamp points: three wall lamp points in the parlour and one lamp point at the middle of the ceiling, three lamp points in the dinning area and one lamp point in the middle. In the rooms; five lamp points each. Just one lamp point at the middle is enough. One can use reading lamp or bed lamp if so desired. All round wall lamps don't add any rental income whatsoever.

This practice is very wasteful as one can save easily about 70% in pipping and wiring cost if just one lamp/bulb point is adopted in the middle of the room as is the standard practice here in the UK. See pic below, no wall lamps but still well presented living area.

What's your top three wasteful practice anyone?

1.Block setting mortar for sure.

2. Roman columns.

I'm going to have daisy chained multi-wall outlets. I utterly detest seeing extension cables.

Steel goes a long span than timber and as such requires less trusses than wood. And the spacing from truss to truss is wider than wood

Because steel goes a longer span, it does not require joints unlike woods which requires joining of woods to make up the length which is additional weight on itself. Steel can span 40ft. Hardly can we see wood of 18ft or 6m.

In my ongoing project, I have a span on over 11m which cannot be acheived without joining lengths of timbers. Now this joints and braces add up to the overall weight of timbers.

i have been wondering if the measurement was right mere seeing the pic u attached and oga mufu's building that was uploaded weeks ago.

I will confirm the size properly later. It's just a little sitting room and 2bed penthouse plus balcony where u can view and relax

#3 - Agreed, why installed pointed lights? I don't get it either... what about those wall lights installed in four corners of the room?
I argued with my brothers on this too... he said that is the norm. So I agreed but never installed more than two bulbs... not four.
And we no even get light sef, more lights put heavy load on generators.

#2 - It's just good fancy for a residential building at least the precast type, low cost, but rental probably not for me at least...

#1 - This I still don't understand... if mortar is not use for setting blocks, what else can one use... please give me some alternatives and their advantages and disadvantages...

Thanks.

@Hajji M

I observed a lot of wastage of Mortar, over time, in certain builds l have done and personally supervised.
When they finished laying the Blocks and we had to pack the remnants of mortar of the floor, l was shocked because in one case, we had to use it to just fill some areas of the compound.

In my own opinion, apart from the craftsmanship of the Bricklayer themselves, there are two reasons l noticed

1.) The type of HOLLOW blocks we use in setting walls: Compared to flat blocks, hollow blocks tend to waste mortar a lot, some fall inside the holes, others get pressed out of position on the block below and the "rubbing process" scrapes off the rest, onto the floor

2.) Badly shaped hollow blocks: Having blocks of irregular sizes (abnormal shape, abnormal size, either to thin or sloping, e.t.c) all contribute to mortar wastage as you have to use the mortar to "make-up" for the irregularity, in other to get a straight wall.

If you observe the way Red Bricks are set in foreign lands, you will see that they dont waste Mortar and it is always very neat and straight..... due to the shape and type of Bricks used

The distance between two intermediate support in lightweight steel roof construction is over 8m. You can never try that with timbers which means less trusses for the steel.

The most interesting part is that lightweight steel are self supporting and the weight is not imposed on the structure but on the beams. This explains why you can see a steel roof built without resting on partitions. Timbers (ordinary) cannot achieve the same feat without supports except it is engineered.

I have a good idea of the riveting, welding and use of aluminium screws to tie down stuffs to it so, that is not important to me.

Ijebu man! Na money side you see

It's almost the cost of timber roof + 50%. The bulk extra goes into installations, consumables and workmanship.

Material difference is almost negligible. If you consider it in long term, it's truly worth the extra cost.

I'll be expecting your PM and I believe one day Nairaland Properties will be recognized in Nigeria as a force to reckon with on innovative ideas.

We all need to work together to make Naija great again.

A lot of thing (especially Rebuilding NextHome) is taking a toll on me cos I run a one-man show now hence the reason people don't always meet me at the office couple with the fact that banks and multinationals are retrenching so "who born my monkey" to dey show himself at this moment.

But trust me baba, I'm up for this creative thoughts and I have a very good platform to put them into practice.

Do you still remember the Parapet Steel Mould I shared some years ago? You can just produce parapet without the usual headaches and worries of carpentary work. No woods. No carpentary work. These are the kind of things I love.

Next time you're at Lowes or Home Depot saunter through their construction area.

Hajji M.

There are no alternatives to the Mortar, which are economical, that l know of (use of GUM is one but it is not economical, especially with our present state of doing things).

We then have to take a second look at the Hollow blocks themselves.

* Can we make them more straight and to very specific sizes (length and thickness)
* l also mentioned in one of my previous posts on this thread that with a tool like the "Bricky tool", with a little more tweaking, l can device a means of adapting it to Hollow blocks such that the Mortar is prevented from dropping into the holes.

That will finally nail it and makes the job faster, easier and cheaper
