sign of weakness

www.engineerosaz..com is where you find latest prices of all building materials in Nigeria and lot of construction advice for your project from the contractor of first choice. Check it out

Wow! I saw similar works while abroad. I hear its a highly technical (surgical) operation on foundations. PPE on point too. This really will save the cost of demolition and reconstruction. Thumbs up Engineer, more pictures pls!

I read this and thought i should share;


USING BAMBOO IN PLACE OF IRON RODS IN CONCRETE
Engr. Osaz' Enobakhare (StrutE)
July, 2017

There are now sufficient reasons to appreciate suitable alternatives in today’s construction. Whether it’s due to cost considerations or environmental factors, exploring alternatives is highly welcomed. Being the world’s most commonly used building material, nearly all our buildings have a signature of concrete on them. Unfortunately, the cost of a cubic-metre of concrete produced in Nigeria has nearly doubled in recent times. The price of iron rods (or steel rebars) is also largely unstable; swinging here and there like a triggered pendulum. There seem to be absence of any serious price regulation mechanism and the manufacturers also have their own side to the story – exchange rate issues, increased cost of raw materials, taxation and all sorts. It is not clear whether the building industry has any special provision for the average person or the common man. Interests charged on financial loans are not encouraging. You can go on and on; but complaining is obviously not the solution. They say if life gives you lemons, make lemonades out of it. Here we are; we need to reinforce concrete to maximize its potential and we have got an option –bamboo.

Tested, tried and trusted, bamboo has appreciable tensile and compressive strengths making it suitable for use as reinforcement in concrete. With ultimate tensile strength reaching 124N/sqMM, it only takes a combination of bamboo strands to equal the 250N/sqMM ultimate tensile strength of mild steel and 460N/sqMM tensile strength of high-yield steel rebars in common use today. More so, provision for bamboo reinforcement in concrete is structurally designed in the same way as steel rebars; the mix ratios and construction processes for bamboo in concrete are not different from the norm, making it not necessarily a change in technology but a change in the material used. It’s that simple! There are around 15,000 species of bamboos around the world; the suitable variants are abundant and wasting away in our mangrove forests and elsewhere while we simply look away. There is need to put on a thinking cap and intensify research on the use of the naturally-occurring bamboo which is bio-degradable and eco-friendly than the carbonized steel rods. However just like every other construction material, bamboo has its own limitations; perhaps that is why it has not been approved for use in fully load-bearing members. Does this mean it can’t be used for concrete at all? No!

Bamboos, like several other plants when placed in water tend to absorb it and swell. As it expands in the concrete, it makes the concrete to crack. Water is needed to work concrete and there lies an issue. Researchers have provided solution to curing bamboo to be used in concrete so that it does not absorb water as much as it would normally do. This treatment can be done right on the site or through other industrial processes before taking the bamboo strands to site.

my first time of hearing this. Noted

I smell blackmail somewhere. Why not drill your supervising engineer to verify the contractor/engineer's claim of bribery? Corruption everywhere! I know People in this country can make things difficult for you when you don't wet their palms.

Doing this may help open a new can of worms, since the dude that testified in support of him above said he raised such concerns too?

I am about to engage him on a sizable project and its important that i follow up diligently on this matter since he was recommended to me by people of repute and i have actually verified some of his completed works.

I am a female Consultant QS with over 10 years of cognate working experience. I don’t handle projects as a contractor but I can recommend a few good professionals I have worked with over the years based on trust and competence if you don’t mind. I can also provide you with detailed estimates and interim valuation at a reasonable cost.

Oh that was a quick one. I'd study it carefully and revert via mail. Madam, May I know who and who you are recommending pls

Hello NLders,

I’m diversifying into commercial real estate right now with the development of luxury 12 units of 2-bedroom flats in Osapa-London on part of my 1600sqM plot and later an office complex in Finance Quarter, Abuja on an acre of land.

Starting with the Osapa site, can concerned professionals here provide me with rough estimates of what my budget should be in this particular order pls? Just figures pls. Details can come later. Need to move swiftly.

1. Cost of Designs & Approval
2. Cost of Structure (From Foundation to Roof Level)
3. Cost of Finishes (Walls, floors and Ceiling)
4. Cost of External Works
5. Any other associated cost that I may not have mentioned.

Pls note I don’t enter into deals with quacks, only competent professionals pls.

Useful Structural advice and sketches would also be appreciated.
