Site visitation: We visited the site December, 2016 to have a first hand information about the nature of the site before work can commence

Daboomb:
I am the only one see that the house circled in the picture below, close to this site, is already doing a "leaning Tower of isheri"
... even before completion.


BTW: When you get to like 80% completion of your project, l want to bet that those houses nearby will start developing cracks and fault lines.
Most of them are on "unstable soil" and the "pressure" yours will exert within the soil, as it settles down, will shift their base so much that they will think its a small earthquake!
i'll wait to see what happens.

This Client is really lucky to have someone as diligent, trustworthy and committed as Abdul & Podosci working for him.

These Engineering team definitely knows their onions, there is a difference between a building contractor and a trained professional, like 7up advert will say, the difference is clear, the owner of this project should go and sleep because l am certain abdulwastecx and his team will deliver, l like the way you respond to other Engineers / builders who throw questions at you, your manner of response was professional, no name calling but agreeing to disagree and vice versa, you are been watched by different people across the globe who may not even comment on this thread, keep doing what you know how best to do, l know the celestial forces of the universe will continuously crown your effort and l will not be surprised if you are engaged by anonymous guest for other projects even before the completion of this work. Kudos to your team

Please Abdul why is the 16mm qty that high almost close to 12mm?

Marilo:
Adbul/Podosci,

Let me ask these questions bothering me.

I see a whole lot of reinforcement which to my mind will cost a lot of money. so I ask:

1. Is there anything like over-reinforcement at all?

2. Can BRC reinforcement (3.5mm) be an effective alternative for DPC reinforcement.

3. Is there an alternative to the use of iron rods for reinforcement?

AngelicBeing:
From a layman's view the land is a swampy / water logged terrain, reinforcement is necessary to avoid stories that touches the heart infact l will prefer over reinforcement if this is my build than under-reinforcement, looking at the terrain from the pictures posted by the Engineer the land is more like building a house in a river terrain / bed , so l dont think there should be anything called over-reinforcement in a challenging terrain like this, the more reinforcement on the build the better, this is my opinion anyways, let the Engineer respond

Thanks bros for asking a very good question, I will try to do justice to all the question.

"I see a whole lot of reinforcement which to my mind will cost a lot of money. so I ask:" I will start by correcting this little statement. Quantity of reinforcement depend on the results of both the structural analysis and design. In a layman language it depend the structural complexity of the building, soil condition and the choice of foundation used.

I will assume the above statement relate to the quantity of reinforcement use for the raft foundation.The raft foundation was design based on the soil properties and magnitude of load acting on the foundation, the design which was carried out using a specialized structural engineering software gave a satisfactory quantity, size and spacing of reinforcement which was also confirm using manual analysis through the guild of relevant literature.

Answers to your questions

1. Is there anything like over-reinforcement at all?
Ans: There is over-reinforcement: over reinforcement is when you provide reinforcement way over the quantity and size needed for a particular job. When one over reinforced a concrete structure, design philosophy like economy is defeated and mode of failure will change. Over reinforcement is bad on the part of economy and structural integrity.

2. Can BRC reinforcement (3.5mm) be an effective alternative for DPC reinforcement.
Ans: Yes BRC reinforcement 3.5mm is an effective DPC reinforcement but here we are building a raft slab ( which also serve as the DPC level of the building), The raft slab demand a well reinforced slab capable of carry the pressure exerted by the supporting soil as a result of the magnitude of the apply load.
For other type of foundation like Isolated Pad footings, combine and continuous pad footings, strip footings etc you may use wire mesh for the DPC reinforcement ( because the reinforcement is only needed to control cracking) but for works where the DPC form part of the foundation structure like Raft foundation, the DPC/slab should be design accordingly the the resulting design reinforcement should be apply appropriately.

3. Is there an alternative to the use of iron rods for reinforcement?
Ans: There are alternative materials like bamboo but this area is beyond the scope of what this thread was created for.
As result of my love for affordable housing I am picking up alternative materials for structural members for my master thesis.
