@opalu,
I sincerely hope this thread hasn't gone cold because I have a huge interest in building construction and I'll have loads of questions to ask. let me start with these based on the few comments above:
* Does a bungalow require a German floor?
* Is a German floor the same as a raft foundation?
* If a bungalow doesn't require a German floor then how is damping prevented in a bungalow?

still on structure
* how do you determine the weight of a house so as to know how to distribute that weight along the columns going down? for example, if a house weighs say 100 tons and the soil has a strength of about 1ton/msq then I know I need about 10pillars with footing 1msq each (rough estimate I know). but how do you determine the weight of a house?

and then this question I am having a hard time getting satisfactory answer to:
# what exactly is a duplex? what's the difference between a duplex and a storey building? are they exclusive or interrelated?
thanks in advance

The answer is long. Call me with my number at my signature.

THE 6 MAJOR REASONS WHY BUILDINGS COLLAPSE :-
1. Lack of Experienced Professionals:- Most buildings being constructed or already built in Nigerian Cities especially Lagos and Abuja didn't have Experienced Professionals overseeing them. I went to rescue one Estate Project of several mansions that was built without a COREN Structural Engineer. So I had to redesign and reconstruct a good number of column points to make it stand. The Buildings were already at Decking level!!! One of the Mansions is sold for hundreds of millions yet a professional couldn't be engaged till there was problems.
2. Using of inferior materials:- Some clients deliberately tell workers to use low quality materials. While others want good quality materials but they want to buy by themselves. And when they go to the markets, the sellers will know they are JJCS and sell them inferiors at higher prices. The Site workers would accept and then use without complaining. After being in this field for a long time, I would simply reject such materials because many people will die in the next 5 to 10 years from that day.
3. Faulty or No Structural Design:- 80% of clients only know about Architectural design but don't understand the role of Structural design. The effect is that they want to be "begged" before paying for what will make their building to stand. they It is the Structural that design that shows the Position and sizes of Columns (pillars), it shows they type and depth of Foundation, it reveals the details of all structural members of your structure.
4. PRIDE- Many clients are proud. They feel they know construction more than the Professionals when that is not their line. They read some few things from Google and they feel that they know more than someone that spent 12 years in Tertiary institutions and15years in the field.
5. Other Professionals taking the role of Structural Engineers. A Surveyor or Architect or Geologist or Mechanical Engineer or Electrical Engineer etc CANNOT take a place of Structural Engineer. The Structural Elements are the Skeleton & Muscle of the Building. If the Bones have problems no matter how much Makeup you do or how nice your dressing it won't solve the bone problem. You need an expert in that field to solve it.
6. There are Some Bad Eggs in our profession who though experienced They charge very high prices and they know Packaging. They know that Clients like Efizy and they give them swags. How do you know such people? They try to confuse you with excess technical terminologies. Some tell you the weight of the equipment they will bring to your site, you give them the work, they give you below what is required and shortly after that, buildings start cracking within 3 years. Clients who don't value Truth always hook up with these people.

WHY MOST COLLAPSES TAKE PLACE:-
1. Lack of Experienced Professionals:- Most buildings they construct in Nigerian Cities especially Lagos and Abuja don't have Experienced Professionals in it. I went to rescue an Estate Project of 30 Mansions that was built without a COREN Structural Engineer. It was only a Corp member Civil Engr that I met on ground. So I had to redesign and reconstruct a good number of column points to make it stand. The Buildings were already at Decking level!!! One of the Mansions is sold for hundreds of millions yet a professional couldn't be engaged till there was problems.
2. Excess management of money to buy inferior materials:- Some clients deliberately tell workers to use low quality materials. While others want good quality materials but they want to buy by themselves. And when they go to the markets, the sellers will know they are JJCS and sell them inferiors at higher prices. The Site workers would accept and then use without complaining.

5. There are Some Bad Eggs in our profession who though experienced, they are also Experienced crooks. They are after quick profits and they don't care about your project. They charge very high prices and they know Packaging. They know that Clients like Efizy and they give them swags. How do you know such people? They try to confuse you with excess technical terminologies. Some tell you the weight of the equipment they will bring to your site, you give them the work, they give you below what is required.
