Good Evening all, My name is Anthony. I am very new to nairaland as a matter of fact today is my first day on naira land and i must say, i am really impressed with what i have been reading so far and the pictures that have been coming in. I am a geologist and also an architect. my love for construction drove me to obtain a second degree in architecture.

I really look forward to learning a lot from this tread.

Fly ash(Quarry Dust) is the best option for replacing sand added to precast concrete.

Though you have to be really careful when you make purchases of flash ash. Its not just dust from quarry's, There is also a process in producing flash ash. You should really take consideration in the class of fly ash being used. If not well produced it might be hazardous both to human health(though Over a period of time) and also to concrete mixtures.

Fly ash can indeed be used for so many building applications like Soil Stabilization, As a replacement for cement in concrete mixtures(Be very careful though if the wrong class is used it can cause the precast mixture to loose its resistance to water and think of the many hazards u possibly can think of) even in damp proofing...(wait till you see my damp proofing solutions). If the Right class is used it increases the strength of concrete mixtures,block mixtures...and even improves the curing time.

If you want to build a house today much care and attention should be given to strength of materials used. one might have the proper Rebar construction for your beams,columns,roof slabs etc.... but with the wrong materials and mixtures, The story of a project might be like that of SOLOMON GRUNDI.

Aventures I am so loving the material used for your deck form work. Thats quality work and material prevents air spaces in your mixture good choice.

Have a blessed week Nairalanders.

now making sense

kkonsults:
Welldone sir.. nice work..

EgunMogaji:
Sorry Oga, I'm trying to be a good student.
I am confused because if you still ended up doing a floor then where is the money savings? Or the owner just wanted to come back to tackle the expense of the floor?
Thanks of taking the time to answer, I appreciate it.

Culled from one of the great Aventures' classes.
Pix 1. Damp roof admixture (sycallyte) being added to the capping concrete mix.
Pix 2. Capping concrete in place to prevent dampness, used to perfect our floor level yet to come and to be used as reference point for measuring out our lintel level and other measuremnts
Pix 3. View of the capped area.
Pix 4. More view of the capped Area.
Let's discuss this with regards to it's advantages over German floor and how effective it is to prevent dampness.

brabus:
Could it be the wonder working "cellular raft" foundation? A lot of residential projects in Lekki can actual survive harsh soil condition using this method without pilling. Even worse terrain in Ori-Oke, Ogudu area (but definitely not Akoka o) survived using this foundation.

Patiently waiting for the unveiling of the new type of foundation.

Respect Oga!

does the above cost include the cost for the parapet. if so which type pre cast or otherwise.
also does the below cost still stand to date.

@Donswampo, @all

Structural engineers work their whole careers designing a non-breathtaking and normal structure but yet the everyday structures on which we all travel and in which we all live and work.

Unfortunately, when a new house is built or considered by a homeowner, designer, builder or developer; little thought is given to the loading or load resistance of the structural elements supporting the house.

The primary focus of majority homeowners, is always on the floor plan (at least I can say that with authority on this platform), landscaping, and finesse. So, the structural elements that supports the house always receives little or no structural engineering input.

I'm lucky to have worked with big engineering guys and I can say it with authority that structural engineering is fun if you can be attentive.

Take a look at this simple scenario of how we build here on Nairaland:

Mr A wanted a residential building. First, he start to look at the area he'll like to live. Next, he start thinking about the house itself. How big, how many rooms, and the shapes. He gave very little or no thought to the structural elements which supports the house. He called his designer and they came up with a fantastic house with interesting features like the helical spiral staircase, unsupported beams spanning over 6m, wraparound terrace on 1.5m cantilever and many more. The next thing, he came online to ask for quotation to build the modern edifice exactly as the 3D presentation. Got a builder and construction began.

At what point did he require structural engineers input? Point of construction (just as you came and ask how a staircase which is an integral part of the building will be constructed)? Or while the idea is still on paper? That's how we roll and what leads to 99.9% of structural failure we see today.

Now, let's look at the following variables:

A floor plan is a floor plan. But two parcel of land are never the same. One land may be sloped, or adjacent to a river, while the soils of the other may have low bearing capacities or have a high water table. What about bad weather during construction? The construction practices to be adopted on Site A and B always differs, so also the skills and technical requirements.

So my questions are, why aren't Structural Engineers more involved in our designs at the conception? Why are we more particular about the cost, the materials and the esthetics?
Why aren't topics like the strength, stability and durability of structures, interpretation of building codes, calculation of stress, discussed until there's a major need?

Why aren't SE's more involved in our projects? Anybody can design, we have thousands of DIY homeowners but how many can design a structure considering the different variable and conditions of a given land?Oga Brabus you make a nice point, but I disagree with you that the structural engineers are the ones not up and doing. Most architectural designs that comes to us are nominal and common residential designs and so what do we do. In cases where we have challenging site soil condition some architect (the first contact of the client) often do not do enough to orientate clients. The reason is not far fetched, instead of organizing a meeting that will involve all the stakeholders (client, architect, structural engineer, soil engineer) most architect will not do this because they prefer to keep all other professionals hidden and then charged the client on behalf of all other professionals, thereafter the architect will come and claim that the client pay token so we should just manage 40k whereas he has collected like 120k on your behalf even after delivering the job he wont pay you up claiming that the client is owing him and that goes forever. Now tell me how do you expect such structural engineer to do a good job.

Structural engineer can not face any challenging design except (1) there is a superb architectural design that differs from everyday design and the client is also ready to pay the price (2) Also there is no major challenge when the site soil formation is firm or rocky. I wish to refer all of us to the video clip of the design and construction of Alburj hotel in Dubai (the Architect and the SE are young brilliant chaps in their mid 30's from Britain) The location and several features of the project poses an unprecedented challenges and they face it headlong and they were successful.

And many atimes the client will shout you down and tell you to do it the way baba biliki did their grandfather's house, as for me I do walk away from such project but some SE will concur. For instance I met a client recently unlike the baba biliki followership the man put me on my toes and we now have a brand new foundation type that can help reduce the depth of piling, reduced the number of piles up to 60% less ' more reliable foundation. Both myself and the client worked really hard and thank God we are done and we ll soon unfold the details.

I noticed that the reinforcement for the pillars on the ground floor has 6Y12. Is it because the building is 3 floors.
Will there be reduction in the number at higher floors?
Thanks
