Please i need a piece of advice on lintel in storey building, some are saying it is better to do lintel all round while others are saying that doesn't make siginificant impact since there will be beams to support the structure lintel should be fir openings only. Please i want to hear your views

Pesonally and economical to me... wasteless.
The decking beam should tie everything together at the top. But for bungalow, I must have it.
Just my unqualified opinion, since I am not a COREN certified yet.

Having a lintel all round a bungalow is uneconomical and not necessary. One could have some variations at times might decide to use it for different reasons though....anything is possible depending on the individual conditions...
Nb..I have been following your posts and they are very intelligent Sir... Weldone Sir.. ..I am.not coren certified yet also.lol

thanks for your professional advice

From experience as a Practicing Engineer, Lintel is called "In-built beams" wish are normally constructed on windows, doors and other open partitions..
To the issue at hand,,,

Your choice of doing lintel round or not depend on the Structural Design Calculation prepared by the Structural Engineer in charge of the project (Storey building)..
You must have experience some completed buildings having cracks at some portion of the building.... what is the cause of this?

1, Poor workmanship
2, Differential settlement..

Poor workmanship can be taken care off with adequate supervision..
but Differential settlement has to be handled by the Structural Engineer when designing at the initial stage especially if it is a water logged area... in-built beams calculation will specify if there is need for it to go round or not.. taking account the Soil bearing Capacity of the build..

To cut the long story short.. Dont want to go into Technical details.. cos i know how boring it is for other proffession

There is a rule of thumb i gave my pupil engineers or my bricklayers as the case may be,,

At interval of block wall not more than 6 meters, in built beams /lintel/ ring beams of standing column must be constructed to serve as link or chain to the block wall..

ask your self... can crack due to little differential settlement penetrate through lintel? No..

because reinforced Concrete resist Shear more than ordinary block wall.. this is to hold the block wall tight in place in case of any deferential settlement or poor workmanship on the foundation...

Oga Mufftau have always been lucky with his structural designers...
he avoids water logged lands and have taste for good workmanship..
but still ... experience structural engineers are needed in a building Construction..

The building collapsing today are building built many years back... The failure keep accumulating till it eventually give way..
i have been called to come remedial more than 1000 structural corrections on buildings, i just smile at the level of ignorant of the owners saying... "Mr A and Mr B did it like this, that is why me Mr C did it too.."

the money they use for correction will now triple what they would use to hire an experienced Structural Engineers..

IT IS WELL..

Please, what's foundation watering?

micgray100:


Foundation Watering is an interesting topic. Geotect Engineers do more research on this topic. Though I am a structural engineer, I will try to explain a little I know.
We all are aware that generally soil behave like sponge. It shrinks in dry season and swells in wet season. This shrinking and swelling of soil around foundation causes movement of structure to and fro. This movement most times are very insignificant but often causes little stress on structures and return to it original state if no damage done.
In view of the above, Foundation watering is a way of keeping the moisture content of soil surrounding a foundation within reseanable limit.. I mean almost constant. This can be done by inserting horses a little closer to the foundation walls or concrete as the case maybe.
It is to be noted that the above should be controlled as much as possible.. As to much water may reduce the carrying capacity of the soil which may pose another challenge. Depending on the distance where water is place and the foundation wall.. And any absorbing water elements like trees around your structure.. Expert advice is always needed in foundation watering..

johnson232:

Sir is it necessary to do lintel in storey buildings or not, since there will be a beam before d slab
Pls help with a simple reply...yes or no?
Your first reply seems too technical & not hitting the nail on the head

johnson232:

U're bless sir,I'm grateful... I have decided to settle for a mix ratio of 1:4:4 for all the concrete works, both for columns and lintels. Hope that is okay?

To whom it may concern please i need advice I'm about to erect water tank stand i would like to know how deep it can go and what size of h beam to be used about 5000 liters capacity thanks in advance.

HajjiM Thanks the house is a bungalow and i contacted one person he was saying he will use 6x3 and the height should be 30ft . But i was not convinced that's why i decided to make enquires.

Lenght .step. basket.casting.crossing. i need further clarifications " I'm new on naira land and the project is on now as I'm typing now. Secondly i need information about interlocking i want to do it .joforndu@gmail.com

Please..I will appreciate it if nairaland can answer my question for the 1st time..My Engineer did a deck and 3 days later it is cracking.see pictures. What is the cause and remedy?? He patch it upbefore we could see it

shileowo:
i need advice on my property please. Drainage is channel to the back of the house due to level of floor.the road infrastructure is higher in the front so any attempt reverse this would mean a discharge pipe will be lower in the gutter which will be dagerouse in the rainny season cause water will flow back into the house due to high level of water in the main gutter. What are my options. thanks
