I think a better way to render the bolded is

“Build your slab on fill so it doesn’t act like a suspended slab. “

When suspended slabs are designed, one of the main thing we design and check for is Deflection.

Owing that your ground slab is sitting on a well compacted fill material plus hardcor, we are not supposed to experience any form of deflection.

Hence it shouldn’t act as a suspended slab, and as such should not be reinforced as one.

Solid or penny wise, pound foolish?

We carried out Pile integrity test on our pilling work...

Aforxzy raised a valid concern yesterday but like she always do. She went awol without getting the perspective of the other side.

Have a look at the picture below.

The point where I had the caution tapes was where we were supposed to have a column in our proposed structural drawings.

While carrying out our preliminary site survey, I raised a concern that we cannot have a column at that point (not for aesthetics but safety concern).

So we redesigned the structure to have a cantilevered beam and we move to site.

During construction, I’ve personally witnessed cars hitting the scaffold at that point and we had to put caution tapes on it to alert people driving around the site premises.

As a good manager, you don’t have to wait for it to happen to understand how to prevent occurrences in your sites.


One of the thing that has helped me so far in construction is the way we learnt project management and the person who taught me.

The only things we discuss in meetings are dependencies, deliverables and challenges and we are always ready to learn from others.

I had the column removed in my build in order to optimize the ground floor parking space design from the aspects of column network layout.

For me, it’s a case of choosing functionality over form (aesthetics).

Not having a well structured column layout can/will affect a car’s turning radius in a multi dwelling apartment.

Reeefe:
How are dey supported?

Reeefe:
How is is able to suspend as long as it is?

Are u sure those engineers that construct event center know these? If yes why do dey keep putting columns that become an obstruction in d space?

Hello chief . When doing German floor after the foundation has been filled with filling sand and allowed to settle for 6months, would it still be necessary to rammer it b4 settle the level for the German floor n pouring concrete?

Ps: in this scenario the bungalow has been raised up to the leveling n even roofed.

If it is not done on site or in situ, can we call the prestressed slab, precast?

rotecch77:
Let me quickly give simple explanation about PRESTRESSED CONC,as I said yesterday.

prestressed concrete involves the stressing of wires or cables ( aka Tendon) by anchoring them at the end of a metal form, which may be up to 120 m in length. Hydraulic jacks stress the wire as required,

This method doesn’t used regular iron rod, the tendon arrangement also is totally different to normal reinforced concrete.
We have 2 method of prestressed conc
1 Pre-tension method
2. Post-tension method

PRE on prestressed conc doesn’t mean PRECAST conc,
All precast conc doesn’t mean they go under prestressed method of conc formation.

See attached pics of prestressed concrete system

azizola:
Good day! Pls can someone explain this to me?

Tochex101:
Did anyone see the video that trended early this week of someone using bamboo in place of steel rods in Anambra state?
I could have attached the video but don't know how to....
Our pros here, what are your thoughts...

toluxa1:
Please is there anything that can be done about these greenish stuff on the interlock at the back of the house? To eliminate or reduce it. It makes the backyard really slippery and messy to walk on. Strangely, it's only at the back and not at the front (2nd pix)

I welcome my TWIN'S last Tuesday but yet it's hasn't reached front page

n3xt:
True! That’s why you’re Aforzy 🙏

We have 8.5m clear span supported at both ends.

Even the 16.1m beam in the existing structure had some very interesting diagonal (transfer) beams.

Thanks for sharing!

You matter 💯

Preparing our third 8.5m unsupported beam 🌚

Isn’t God the greatest?

It’s non slip tiles for outdoor areas… stronger than indoor tiles

Stamped floors are beautiful but when it comes to durability, I'd go with interlocking

QSFemi:
Good morning People.

Attached are pictures of POP Ceiling that fell down recently.

It's a common phenomenon to have POP Ceilings falling down from their place after some reasonable length of time. This can cause serious injury to users of such space.

I think it's time structural engineers supervise the construction of POP Ceilings. Most POP Ceilings are done by tradesmen who don't understand the stability of structures .

The roof is overwhelming on the building more block wall should have been added to increase the headroom.

FEGEITOK:
I use this ratio as my minimum ratio and every time I do the workers marvel at how much granite I am using. They complain that they are not used to that much granite being used.

I have used both 1/2-inch granite and 3/4-inch granite.

In fact, I was once called Julius Berger for my insistence on the quality of concrete mix.

Once when someone had cause to break a portion of the concrete the workman shouted, do you want to build an everlasting house? This concrete is too strong!

I wash the granite that I use to create a 4'/6"water barrier, but I have never washed the granite that I use for the concrete mixtures.

Going forward, I will.

I even use reinforcement (TMT) for the concrete floors which the laborers said is a very rare event.
