We are doing great

Soak away excavation continues alongside sun-structure block work

Lets handle your piling works

Shore fence line piling works ongoing

We are excavating already for soak away pit so we can use the sand for filling
Our size of soak is 3m x 3.6m x 3m

Sub-structure block work continues

Not necessarily around owerri but outside owerri Town like naze, emakuku.
Thanks anyway.

Welcome bro

What’s that structure that needs deep foundation in this our terrain?
A multi-storey building?
A simple duplex?
A Telecom tower?
Let the professionals handle your pile foundation

@ malkomx first I must congratulate you for the good work you are doing but I must also say to you that you don't just post pictures to us on this forum without taking us on various steps which you carry out to get we you are secondly the need to state cost of materials with this we the members on this forum will be able to know the Cost of various building materials within the location which you are doing the project and sure others who wish to start sure building projects will be able to know whst is head of them thanks

Thanks for the feed back
Going forward I will indicate as applicable
Thanks again

Which particular town in owerri.

I want to buy a land at an outskirt of owerri, just like 15 minute drive into the city and my budget is 2m. Do you think it will be possible?

We are working inside my client’s community
With 2M you can’t get a plot in an area ready to be developed around Owerri (to the best of my knowledge though)

Let’s do your deep foundation in south-south / south-eastern states

We have commenced sub-structure block work

We have proceeded to install starter bars and cast foundation footing

You can view our thread on 6 Nos 2-bedroom flats construction in Portharcourt on the link below https://www.nairaland.com/2634234/developing-two-storey-building-6nos-2-bedroom

Excavation of the foundation trench follows immediately
While iron benders are busy preparing rebars for sub structure

Site has been successfully cleared and setting out done

Hello NLanders
We are here in the outskirts of Owerri
Proposed building: four bedroom duplex
Client: NLander
Ground floor:
Ante room with visitors WC
Main Lounge
Dining
Kitchen
Laundry
Guest bedroom (en-suite)

First Floor:
Family lounge (with front balcony)
Master bedroom (with outside balcony)
Madam’s bedroom (en-suite with outside balcony)
Children bedroom (en-suite)
Budget: 17M
Scope: building carcass with stone-coated roof tiles, plastering (+ Aluminium Casement windows + Turkey security doors and Chinese internal doors)
Design and construction: EMX Buildworks Ltd

Here we go,
4th milestone complete.
Congratulations to the EMX Buildworks team

And here we are with the roof works
Carcass first

Next stage is concrete fascia works
Progress!

Getting there

After the break, we are here to resume work on this structure
2nd Deck block work commences immediately

A structural defect in a building is an actual physical damage to the designated load-bearing elements of the building. Caused by their failure which affects their load bearing functions to the extent that the home becomes unsafe, unsanitary or otherwise unlivable. Causing damage to persons, property and usually resulting in financial harm.

Building elements are either structural or non structural.

Defects to the non structural aren't that life threatening but could lead to some level of discomfort and the include: defects in brickwork,
Dampness in building,
Defects in plaster and tilework, etc

On the other hand, structural defects include cracks in foundation,
Cracks in floors and slabs,
Cracks in walls.
These are all serious signs that load bearing elements of the building have failed and if not checked could lead to total or partial collapse

All efforts are essential to prevent structural failure

There are several causes of this failure and there is a requirement for a proper analysis of all these factors before construction

Reasons why structures fail

One reason: defective construction !!!
Factors that lead to defective construction:

1) Defective design:
Where proposed loads have not been properly calculated and thus ACTUAL loading conditions of the structural elements have not been determined

Proper geotechnical analyses not done to ascertain soil bearing capacity and appropriate foundation
2) inferior construction materials:
Because loads are calculated for materials of specific characteristics, even a properly designed structure may fail if the materials are unable to withstand the load.

3) poor workmanship:
Even with satisfactory design, quality materials; actions and inactions of the building team ( skilled and unskilled) can result in failure

We have seen that improper design, inferior materials and bad workmanship are the factors that lead to defective construction.

It is therefore key that owners, designers and builders be adequately knowledgeable about these factors and undertake all preventive measures to avert them.

And here is a way:
Design:
Correct structural design, even a mistake or error is not acceptable!
Structural engineers are therefore required to be exceptionally careful and methodical when calculating for loads in all load bearing members of the structure.
All failure modes need to be examined using modern software on the subject

Proper soil investigation must be carried out and a detailed report presented to be relied on in designing the type of foundation

Finally, since the designer cannot be wholly confident about the design, an appropriate factor of safety is incorporated into the design calculations.

Thankfully our engineers apart from being overly playful in such forum as ours, are pretty good with what they do and are doing greatly with designs of structure and usually, building collapses recorded in this country are rarely their fault.

Inferior materials:
Materials for structural elements in buildings include steel reinforcement bars, sand, cement chippings, and water.
They are rarely inferior

This pushes the blame for structural defects in building construction to poor workmanship!

Poor workmanship:
Workmanship here spans everybody that is a part of the building team. From the consultant structural engineer to the artisan and the site help

The engineer who interprets the drawings on the site must be adequately trained and upto date with realities on the site.

Steel reinforcement bars of appropriate sizes must be properly tied and placed to achieve the desired strength in concrete members (all lappings must be to specified lengths)

Concrete being the chief material for structural members must be properly batched (according to specified ratio),
Properly mixed wether manually or mechanically with mixers (it is advised to mix large amounts of concrete mechanically to achieve uniform mix) with adequate water for specified slump.

Concrete must be properly placed and vibrated wether manually or mechanically with poker vibrators to expel trapped air from the mix and avoid "honeycombs"

Shutters must be properly fabricated, positioned and braced to receive concrete

Adequate concrete cover must be given for the reinforcement bars to avoid exposure to air and consequent corrosion.

Proper time must be given for concrete to cure before shutters are removed.

Gravity will help keep your building stable if all its vertical members are "vertical" else same gravity will pull the same building down if vertical members are not truly vertical.
So walls and columns must be made 100%vertical using spirit levels. Same with horizontal members except where slopes are required like in bathroom floors.

All these and other activities in the building site are made possible by good workmanship.
Here in Nigeria a mason with 10-15yrs experience automatically qualifies as an engineer!
A helper who sees the difference in pay between himself and his master resumes tomorrow with tools and parades himself as a skilled personel

It is therefore advised that building construction activities be left for professionals

Hand over your building project to a professional, pay his fees and leave him/her in charge...
And we can have a society devoid of the hazards of structural defects in buildings.

A collapsed building is an avoidable disaster!

As work continues on the first floor

Oops! Sorry my peeps for the long break. My client wanted it as a result of financial issues.
While I moved deep into the hinterlands of Imo state to do some small developmental projects.
Give or take.... we are back and this job continues.
Sorry for the inconveniences caused my audience and thanks for the understanding
