Here is the big picture

More on block settings

Let us raise our walls

Oversite concrete pouring

Mechanical compaction

Back filling with Laterite soil

Using laterite soil (clay )as back filling material should be done well and carefully

Introduce water to allow for proper settlement

Compact effectively to remove voids to avoid future differential settlement

In our case we watered for couple of days and compacted with a mechanical compacting machine

This things takes time to come out clean and crisp like this.

Weldone sir.
Mind giving me one of the apple?

QSFemi:
I agree on the need of structural design for this structure especially with its Kilimanjaro roof skyrocketing towards the sky. Can this roof withstand wind impact?

Yes.
Provided an engineer is involved and some necessary factor of safety are implemented in design.

More so, wind load on a building is highly affected by its surrounding, which may be the shape of nearby buildings, height of buildings or distance of surrounding buildings from the principal building

twinskenny:
Happy Sunday everyone

I am more concerned that the building is tilting

I might be wrong tho, might be from the camera position.

In most cases, bungalows are built without structural design, but this right here needs one (A profound one).

EgunMogaji2:
I’ve said this before and I’ve been heckled down.

The architect owns the project and everybody else subs under him. On a serious project. At least in the USA.

Architects are actually Oga everybody

I cringed when I saw this on one of the site close to mine.

This however is a honest appeal to all M and E guys, this is all shade of wrong and it will affect the structural integrity of the building.

When in doubt, reach out to fellow professionals on the project. On every project site, communication needs to be in sync.

walexProjects:
This one is normal.
I was working on a Project on Friday.On the site Plan the distance between the External wall and the main building at the back is 1.03mm.In order to erect your water tank alone,
For a 2000l water tank,the Internal diameter is 1.45mm.i was like how will that work?
That's not all, I noticed more than 5 others mistakes on one drawing alone.

Most Architects considers Aesthetics and not functionality of a building.
Both should always be considered and when you raise the RFI for it ,you will have to go through a lot of hassle for it to be change.

This gap has been bridged by BIM (building information modeling).

BIM allows for multidisciplinary collaboration in real-time. All parties have access to all the information relating to a project in its current phase and are able to communicate with all other parties simultaneously via the building information model. The advantages of this process are centered around improved communication and coordination and include early detection or reduced risk of mistakes or discrepancies resulting in less rework, reduced costs and improved quality.

Any architect, structural / mechanical or electrical engineer that has not embraced bim and the numerous advantage it brings is not ready for industry standard practice.

Lunarrz:
The iron bender that did the decking are to be blamed here. I think they didn't put internal beam across before reinforcement and you supervisor must be crappy for not speaking out

Hidden beam on floor slabs are just imaginary strength enhancement concept.
The use of hidden beam are not beneficial to the behavior of slab. The principle that deflection of solid slab obeys still remains constant. ( Depth)

The longer the slab span, the deeper the slab should be, some persons have wrongly adopted the 150mm (6’’ ) thickness. Well it’s not a one fix all thing.

It is also worthy of note that slabs are majorly designed for deflection rather than strength, and as such there’s a permissible value for it. His engineer should investigate that and advise him further.

To the OP
Cracking your slab and recasting will create a line of weakness in the crack zone, so therefore you need to be careful.

Possible solution
Your Engr might want to consider composite steel beam and then conceal with some creative Pop finishes

BigFrog:
My shop decking is cracking as a result of the ceiling fun hanging rod they put up there. It's not firm. It wobles with the ceiling fan and I now notice cracking allover it decking.

Another thing is I plan to uninstall the ceiling fan. The decking is a new deck ans there is plan to put another shop on top. I was worried if all this will affect the structure and it looks like the deck is not strong.

I need advice from experience personal from this house to advise.

The truth is, while preparing structural design/analysis all of the bolded concerns are usually addressed (cracks/creeps | live and dead load). That infact helps the engineer to arrive at an informed decision on the grade of concrete and diameter of steel to be used for a structural member. (It is now a case of, was a structural design used or was there proper supervision?)

Solution
Since theres plan to add another floor, please get an engineer to perform a nondestructive test(NDT test) on the structure. This test will give detailed information about the slab and further advise will be given.

obinnanwozuzu:
Please which is cheaper? This roofing or the other common type of roofing?

And also which is better?

This have proven to be cheaper at construction stage (if done well, you won’t have issues)

But if not handled by folks with experience or professionals, maintenance overtime makes it more expensive

I will share some of my personal considerations when planning/constructing hidden roof later.

—————

Here are other cheap common type if you don’t want pitch or gable roof.

rmx:
Akala . We have come thus far

I like what I see here
Clean straight lines

What’s the beam (pillar to pillar) span?

amosblisz:
Hello so to avoid cracks, one has to fix up this chicken net on the walls in and out then plaster, is that what you mean?

Introduction of chicken net is more of a reactive than proactive method of preventing crack on walls

The proactive method involves

1)A good workmanship / supervision

2)Using the right kind of sand

3)Ensuring to remove impurities in sand

4)Getting the right plaster mix

5)Doing a proper foundation to prevent movement / settlement

6)Curing (to replenish excess water evaporation)

——

The only point when introducing chicken net becomes proactive ( is when you introduce it between the joint between your column and wall).

Happy sunday

Amastermovic:
fail to cast the btm reinforcement..

A serious structural defect.

debeey87:
It might likely be 2 & 3 one you said. I have attached the pictures. Foundation was done well and we found more places sef

Just like most contributors have said
This looks more like cosmetic than structural

In addition to what every other persons have rightly said, inpurities in plastering constituent (sand | cement | water) can also cause thinline cracks like this.

princenomics:
Please can you share a clearer picture of the chicken net. The one you uploaded is a bit blurry.
Regards

Sorry it just a random photo to drive done my point

Attached is the chicken net mesh.

debeey87:
Opino please: What can cause walls to have crack after plastering. I noticed the crack on a portion close to the decking but it was just that section. Every other part of the building doesn't have any crack.

Thank you

A picture of the said crack will help give a more accurate answer

But here’s what I shared awhile ago on similar case

Possible Causes:
1) Foundation
"is the foundation done properly or better still if the right foundation type was used."

2) Ineffective bonding between the blocks and mortar

3) Plastering mix ratio

Remedy

Get a structural engineer to help you determine if the crack is a major or minor one.
If the latter is the case, before plastering, he should re add mortar to those crack lines in other to create a better bond between the mortar and block wall

Then nail chicken nets to that area before plastering as shown in the attached picture

Sir I don’t know what you are doing
But going through your posts I see a pattern.

Everyone should do their due diligence. Thank you

Nice one good review we need to see on this thread

Patiently waiting for the roofing stage
Edakun

No problem sir

This is now looking like a charade
Everyone should do their due deligence biko

Wow

A lot of water has passed under the bridge.

Meanwhile, thanks to mountmoriah for supplying the reinforcement for our build
