New week and a new month.
May we all achieve all our aims and objective for the month of August. AMEN.

Bosun Shoyoye, 10k due this week current balance is 90K.

Mavverick why not text bosun to get your balance than posting it here . This is just money n not anyone's life . Take it easy bro !!

They just won't listen. They have no regard for rules. Nonsense.

Nice our able mathematical engineer.

What's the cost and structural implication for a bungalow with all external walls made of sandcrete blocks and all internal wall made of polystyrene? Is there any significant cost/efficiency savings? Will this accommodate conduit wiring and mechanical pipping? If the walls are not to be rendered, how do you fill the gap/chink between two polystyrene board?

Further if one adopts all internal polystyrene walls, what's will be the lintel method? How do you tie the roof to the structure?

The Structural implication is you will have to have a structural frame for such a house, a frame consisting of columns, beam and pad footings. The frame cam be made of steel, concrete or wood depending on which of the materials is more readily available at a considerable cost.

It save some cost, neater, faster and cost much less in maintained in the long run. It also constitute lesser load on the foundation, making it possible to save some cubic meters of concrete and steel on the foundation. You also have more flexible of functionality with polystyrene internal partitions since you can remove some partitions and repositioned them as you like.

For polystyrene internal partitions Ulloa don't need to do the conventional lintel on most sancrete blocks, the lintel are cut in place in the factory... More like prefabricated houses.

You plumbing and electrical piping work can easily be fixed into the wall without any problem.

House built with polystyrene partitions comes with a structural frames to carries the roof rendering the wall to be non load do bearing partition wals

My observation from the section of the report posted.
* Your location is within the basement complex of Nigeria i.e bedrock terrain.
* Overburden means formations overlaying the bedrock.
* The more overburden of a porous and permeable formation, the more the likelihood of getting appreciable ground water source. In your report, It is just 6ft (2m) or thereabout and you might still have some layer of laterite or clay which are porous but not permeable.
* If there is no aquifer zone found within the overburden then then next target should be weathered formation or fractured zone within the basement. Do you have any stated in your report? You can confirm from the person that carried out the geophysical survey, if not stated in the report.
* Depth recommended to drill is 240ft - 270ft is much (Stand to be corrected) except there is a fractured zone of interest or the weathered zone depth is much. Note, The deeper you drill the fresher(Harder) the hard rock become.

* Check for history of drilled boreholes and wells around your site.

Happy Sunday to all.

The report is over 20 pages so I can't post it all. The report says there is an overburden depth of 0-2m.

Hello Sirs.

Please help here. A project I'm involved in, an irrigation project somewhere in the North. We have a large fabricated steel tank ( Dia - 11m, height - 6m) is to rest on the ground.

Now we thought we could place them in a ground slab (say 150mm thickness, BRC mesh reinforced) on well compacted Hardcore.

Bit others (professionals too) are arguing that the slab will collapse. If it collapse? Does it mean the tank will sink into the ground?

Ground bearing capacity is over 200

One person was even saying we will need a heavily reinforced slab with downstand beams on pad?

@spyder880

@egunm
@all please input is needed.

From a structural point of view I will like to have more information like the location of the soil strata with that bearing capacity you quoted above.

From experience, I know that the soil with such bearing capacity may be located at some depth below the natural ground level.

From a simple can calculation, I estimate that the tank will exact about 60.02KN/square meters, which is quite high.

Just the guy you need.
abdulwastecx, with this kind of pressure on the ground, what does it mean in terms of constructing what will carry the tanks.

The solution will depend on the location of the bearing capacity that will be able to carry the water tank.

Assuming the adequate bearing capacity is located at a depth of less than 1m.

Assuming bearing capacity is 200KN/m2 ( as stated by my oga above).
Using a factor of safety of 2.5
We will have =200/2.5 = 80KN/m
Hence, floor loading intensity is less than permissible bearing capacity.

The foundation footprint, area can be 10square meters.

The Platform can be any of the three.

Type one.

Excavate up to 1m below the ground and found the raft foundation/slab to carry the tank but this method may affect your hydrostatic property like the head required.

Type two.

Introduce a frame of 9m columns spaced @ 4m center to center across x - x and y-y axis with three column each across each of the axis. On top of these columns you can have a flat slab design for bending to carry the water tank. Or have a solid slab beam system to carry the tank.

Type three is to excavate all the entire building footprint up to the required depth with the bearing capacity 200. Filled the excavation with hard core of regular sharp upto the surface and then hard a layer of reinforced concrete of a minimum of 200mm thick

Thank you boss. That is a very good, simple explanation. I hope we're all learning.

Is this the section you're referring to?

Wow. Detailed analysis sir.

The location is specifically in Jigawa state

But I used to think the unit weight of steel is 78.5kn/cum. You kind of used 10 to multiply 570.2cum to arrive at 5702kn.

Also sir, I do not understand how you got 60kn/m2.

Please can you expatiate more on the analysis?

Then how do this heavy load translate in the slab design sir?

1. Go a size down for the earthing ( i.e. earth 2.5 with 1.5, earth 4mm with 2.5mm and so on)

2. Estimate the total lighting and power cables for a flat and multiply by 6

3. Optimally locate your meter points ( d/board is obviously already fixed in location ) to minimize the distance between your meter and D/board , it'll help save on load cables

To estimate the lighting and power cables:
-How many sockets .....per b/ room and living room?
-How many wall lighting points as per above
-Do you intend to have pop ceilings and hence pop lighting?

If the rooms are large, and you intend to have pop lighting, the below is an "approximate" quantity , i don't see it requiring more than the below though.

The load cable is listed already.... That's the 10mm

25mm, is that copper or aluminum for servicing?

***Edit, 2.5mm should be 48 not 32 sorry
