So The standard ground floor slab would not require steel mesh reinforcement.The standard slab is a floating slab.This means that the weight of the slab is borne by the compacted hardcore/filling sand underneath the floor insulation & the dpm.so the slab is completely independent of the main structure.The slab thickness is normally 150mm and should not be less than 100mm. You would normally only need steel mesh reinforcement if the floor is suspended
I thought before casting of the DPC, there's need for HARD-CORE stones before casting the DPC? Please explain why you did not use Hard-core stones before casting
Thank you for your comment… so basically we built according to the recommendations of the structural engineer. However despite the fact that laying of hardcore is a good practice, a valid reason not to use hardcore before the damp proof course (DPC) of a duplex in Nigeria includes the following concerns… Poor Soil Conditions: If the soil on the construction site has poor drainage properties or is prone to significant swelling and shrinkage, using hardcore might exacerbate these issues. This can lead to uneven settling or shifting of the foundation, compromising the structural integrity of the duplex. Drainage Issues: In areas where there is a high water table or poor natural drainage, using hardcore can create pathways for water to accumulate under the structure. This can increase the risk of moisture rising through the structure, potentially breaching the DPC and causing damp issues within the building. Cost and Availability: Hardcore materials might not be readily available or could be cost-prohibitive in certain areas of Nigeria. Alternatives such as well-compacted soil or sand might be more feasible and provide adequate support for the DPC without the additional expense and logistics of sourcing hardcore. Construction Practices: Local construction practices and standards might favor other methods of preparing the ground before laying the DPC. For instance, in some regions, builders might prefer to use concrete blinding or other methods that provide a smooth and stable surface for the DPC without the potential drawbacks of hardcore. Structural Design: The design of the duplex and the foundation type specified by the structural engineer might not require the use of hardcore. For example, if a raft foundation or a similar type of foundation is being used, hardcore may not be necessary.
❤Amazing . great job
Thank you
Thanks bro for sharing and this is very encouraging. Please do you mind to share what is your concrete ratio thanks
The ratio we used is 1:3:6
nice job
Thank you…
Pls dont forget to tell us the cost of this project when its completed, thank you
Noted
Great work sir. Detailed explanation but 180 bags for this foundation?
Yes, we had a foundation beam after the first blinding because the place has high water level and low bearing capacity soil…
Nice work sir, i noticed you didn't you didn't use mesh for the ground floor before casting, i thought that's needed 🤔

Thanks for clarifying sir@@UmekRealestate
Nice job. Please, how many square metres is the building itself
It was mentioned in the Vidoe sir

Great technical explanation laced with sound construction experience.
Awesome Design. How may I get this design
