kobocity:
Not just the tank stand alone but every other steel structures too.

My steel fabricator doesn’t weld gate or burglary proofs. He only handle steel structures.

Well detailed and impressive, I kind of like your diversity on most niche of building and engineering , don't forget to add a dedicated structural section on kobocity for some of us to review structural drawing and learn ..most building cost can be strategically reduce by optimizing the structural elements rightly

bixton:
The bold is not acceptable in construction engineering in any part of the world. Any type of design that leads to wastage of resources(material, money, labour and time) is just to hide the in-experience of the individual.

Yes you are very right sir. Every build should be of value , money is not easy to come by , reason most nairaland check on this thread and double check for alternative.

Good morning All,
I need to give some observation, read carefully.
As a silent reader I notice the trend of everyone wanting a steel tank stand, and materials suggestion keeps going on kindly notice the following.

Steel section are choose from expected load (tank size) ..but the bracing are always strategically place to reduce section at times or for stiffness purpose

If a steel section works in Lagos for example doesn't mean same will work in Abuja the wind pressure in each state in Nigeria is significantly different according to the wind isopleth data, so when assume this is always dangerous..

Section like UC, UB Angle iron etc all have minor axis and major axis meaning the direction of face are of important, reason you see people using CHS (recommended sizes) u don't have to worry about any local bending its strong all through .

The base plate need to be check like wise the HDB(hold down bolt)

The foundation this is important and done with three things put into consideration (weight of the steel ,wght of water , wind reactions on the structure ,live load of access also)

Not to bore you much your tank may be over designed (waste of money at least safe sha) or under designed (total waste of money and intending disaster waiting to happen)

A tank stand is a structural elements you should never toy with it because its failure is always a serious issues.

neduboo:
I want to do foundation for my 4 Bedroom bungalow.

The engineer gave me a quote for stage 1 foundation

Profiles #10000
Pilling #85000
Basement #45000
1 trip of sand
7 bags of cement

Please isn't this too much

do u have anything underground(below ground level) in this bungalow of yours.

what's in stage 2

no coarse aggregate

for others to contribute when it comes to crucial stage of work like this u need to tell us what the soil looks like if u don't have soil test..architectural plan included . then considerable opinion can b given

Rexology:
Professionals, please make una help me profer solution to this crack.

The wall section is not sufficient to take the self weight of the beam itself now u have ur roof load wall load and self weight of ur beam on the angle not more than 225mm max..

if the lintel had come out a little beam u could have lap it well there's always a satisfactory lap for this kind of thing it can kills when there's an uplift action from wind and u tie ur roof to this particular member at the terrace

solution from my own view since the load is small u can introduce a dummy column to receive the stress ..safer this way since we can't estimate how solid ur strip is or block..

jajeri3216:
Hello house , there's a crack on the wall which is causing me corncerns.

Is this crack suggesting structural issues?

I don't know if other members already suggested a solution .let me add one or two things,

How many floors is the said structure ?
Is the crack progressive?
Years of Usage?
Residential or any other usage?
Is there a column at that particular edge and can u make a video..

If its your column there's an issue and not something you should listen to the comment of a get a PhD bricklayer, who don't understand load analysis and distribution of a structural system..

Standard Solution

Share your structural drawing
The building will be re analyze to see where the problem is coming from

Structural assessment and integrity test
On all or selected members
Etc..

Kobo kobo solution( Assumed solution)
A UC or UB will be use to support the column and the previous one will be repaired. Assumed selected section..

Note all this if its ur structural element that's is mis behaving

All said above are based on the picture I see solution may changes ..

Be guided professional builder's dear not alter a structural element without approval from the designer not to talk of expert mason

EgunMogaji2:
Engineering wonder. Not sure if it’s photoshop or even Nigeria.

If an Architect here can come out with a likely scheme for this we may check what design requirements will be OK for this..For everyone to know how achievable this is

Callmeboss:
At ODY FOODS we deliver all food stuff to you directly from the farmers

Red oil at #10,000 per 25littes.

I stay in Lagos so is transport included if no include logistic separately and what if am buying let's say 500ltrs will there b discount just as common sense or its flat rate

Mide3367:
I can help with palm oil from Akwa Ibom. 25L keg at 10500 and u buy keg at 1200 per one. DM on WhatsApp via my signature

I will buy a empty keg @1200 pls clarify

Golan007:
Northern Cross River, Ebonyi, Benue.

Thanks

hakeem4:
I believe it would be cheaper in the north compared to lagos

Thanks Engr is there a precise location in the north

Good day Everyone,
Please I need locations state or farms I can buy rice and red oil including Yam cheap ..

omanzo02:
Staslhandel Van Zijl NV, Rotterdam.
Metalhandel Christiaens, Eeklo, Belgium.
MetaalGaller also in Belgium to name a few.

They are big metal warehouse/factories where you can order base on your requirements, it will be produced and delivered to your site. They also produce for known brands.
If you need reinforcement rebar all they need is the measurements, specifications or project drawing.
I have been in these warehouse, the choices are too enormous, there you realise how advanced human technology has gone.

Thanks I appreciate .. Some of our clients needs there construction work delivered in 1and half yrs 2yrs maybe with this we may save time ... After making a cost comparison of this

omanzo02:
The welding are mostly factory done with computer assisted and precision, they also personally do the welding on site with a special spacing tools that give precise results.
I noticed it commonly used in foundations, decking, load bearing floors, light roads(on heavy load roads they uses bigger sizes) and concrete roof.

This is nice I will research more extensively on it pls provide d company name or product name.

When welding is done it may reduces the strength of steel when not properly done reason we don't advise such but on some of the project have work on we usually template on ur rebar for it. Not to move out of position

omanzo02:
Just wondering why are these type of iron rod mats not being used for decking and concrete work in Nigeria? They are readily available for installation, cost less time and work to install.

This will mostly not be recommended because we can't satisfy the welding requirements which is used to connect d bars together if it can transfer the stresses received

The general arrangements of the panel may not conforms with this template and may not satisfy anchorage , lap length from one members to the order..

Don't know if this is easy to move between floors because still is heavy during construction

The bar spacing requirements also will be an issue

This maybe suitable in composite construction of slab though , To reduce crack on a lightly loaded pedestrian crowd walkway

Badgers14:
I have always thought, with the high costs of building materials , why haven't our people dived into this thing... I know they are widely used in the U.K - Europe. I think this was a German engineering.. I could be wrong..

Now, let's bring this thing home..

What are the limitations (if any) in using this in Nigeria?

How would it work for multi story buildings say 3 or 4 decking?

Do you know of any project (specifically a multi story building) that they used this on and how has this building faired over the years??

The reason why you dont see it much here is basically economic view of it .. Explanation below

Its usually recommended in situation where you have a very bad soil and we want your building to be light as strict as possible to reduce foundation cost for you

It makes building a structure very fast because its a plug and play thing like building with steel
exp when you r doing ur foundation first floor to 5 floor will have been produce and ready just maybe 75mm topping to be cast

Quite number of project it as been used for on the island and we have a company in nigeria you send your floor plan to and they check and send back the layout of placing back to you to recheck with your design..

But is it cheaper Not really , its not cheaper as u may have taught but its left to you to choose between time (which is money Also) or going for our older methods..

This implies casting a slab and having to wait 21- 28days to achieve its strength before going to the next stage of work..

..

Nezzjnr:
What about Shimawa

It's also closer to Rccg

Land Is about choice and how close you are presently to the site or relations because you need constant visit but your first step is identify the said property make sure its check from the town planning office .

..Because some advertise their property as shimawa but u will discover u r already at shagamu ..

n3xt:
Simawa is not bad with the number of estates springing up there too. He’ll get good ROI from Simawa than Ofada if it’s a commercial build but he needs to check and check because most land in that area to Sagamu belongs to RCCG.

Yes simawa is really good but he really need to chart any landed properties around simawa well from Ogun state Town planning even any land along that axis including the ofada I suggested ..but d part ofada I am suggesting is close to mowe in 10-15mins ride also


Redeem has a lot of lands yet to be develop around isheri close to wear Obj land is both are damn big and yet to be developed..

Nezzjnr:
I've to go to that Redemption camp area den

I heard they're within range

Redemption camp area is better but I doubt there are available plot there except you are buying from someone try ofada area Also ..land in ofada are also cool and closer and relatively cheaper there ..

Nezzjnr:
Good evening bosses

Who knows about prices Lands at Sparklight estates ojodu here??

i don't know d Price , but I know this few things sparklight is not ojodu its abt 3km to ojodu.. So its basically isheri or use Kara as the location ..the main reason I comment is if you eventually get the property make sure u raise ur ground floor level high Enough ..or ask anyone around walking and working around the water level at that particular side when Ogun river discharge its excess water to its plain ..



Make sure u build right there ..just my opinion though

Good day house.
Practically , what is the maximum distance a beam can span between two supports using 12mm rods for both support and beam.

There's nothing like practically in structural Analysis of structure's, there's a code and guideline so Theoretically

Using 12mm grade 410 rebar depends on the loads coming to the beam example I may decide to put 4 no's of 12mm road in a 3m span beam or put 8no's in same 3m span due to the load coming to it..

But for span in beam is define by how deep ur beam is , so cater for deflection..

Provide d layout and purpose of d design and I will tell you the best reinforcement to use..
But practically without adequate measure it will WORk and fail soonest..

mssiah:
Good morning all

Please I need an estimate. How much will it cost to do decking for the attached plan.

No one can really say how much will deck this plan except you want the quote for the concrete alone which the slab thickness is still needed from a structural drawing and the reinforcement and spacing is required..

Get a Structural drawing for your work first and seek people opinion

michlins:
Good morning everyone. Please I want you all to know that I'm very greatful for making my birthday an awesome experience yesterday.

In that vein,a Nairalander just paid for a single door. Anyone that needs it should kindly indicate his location so I can send it to him for him to check out my work

I need the door what are the remaining terms let me know because location is Lagos/ikorodu

Good All,
please I need block industries number around obalende to lekki or Ajah .. I don't mind having more contacts if you have them at hand ..

Leezah:
can you drop your email so as to have the link.

Send a DM on nairaland or use the WhatsApp link on my signature to msg me..

PS: its trial and error I will provide links to various group available its ur own part to always read the msg and check d one important to you..

U said PhD holder ...I did Civil Engineering and 95% of my lecturer are Phd holder in a polytechnic ..please stop posting thrash from your point of view..

Both are created for different purpose is enough point but one is not superior to each other because a polytechnic student as been taught to address issues logically and realistic reason you need them more on field..

A university student will reason theoretically and provide solution with proof and send this to the polytechnic graduate which in turns take this information and put it to work.

Please don't look down on any degree because now its what you can do and no job out there self for everyone..

Reason u see everyone learning tailoring dragging space with the people we called Artisan years ago to become like them and have steady income and become your own bozz

ChevyHeavy:
Thanks. Yes, it was designed by a structural engineer. BUT, he seems hesitant for me to do the decking first. It's a 5 bedroom semi-detarched duplex with 24 columns 230 by 350 each. Maybe he designed it such that the blocks would carry part of the weight of the decking and he doesn't want to disclose that to me. What do you think?

column dimension are 230mm*350mm each do u know what span this column are apart each (minimum dimension of the closest column) and maximum dimension of farer one..

The beam size is what also.. Asking all this to have a small idea on the said project how many floors..

I won't know the designer motive if I just dish out advice without understanding his/her scheme on your project.

Well you can pm me on my signature the plan and structural drawing to have a check if you wish or follow his advice jejely..

Structural recommendation is not what should be dish out without proper understanding of the scope except some extreme bad practice..

Do you have this said building designed by a structural Engineer?

It depends on the designer motive..
But if its a frame structure sure u can do ur structural element and later arrange ur block wall or arrange ur block and do d decking when u get to that stage..

Difficult to answer professionally , do u have a structural design of d project

yinkarh187:
good evening boss, please I'm still waiting to be added to those groups

Oh am sorry.. Will request for you asap
